My New Movie Server

13 January 2009
PowerMac G5

I’m lovin’ my new movie server. The PowerMac G5 is still a good machine for recording and playing back video. Principal advantages are its two drive bays for RAID-striping up to 2Tb and built-in 5.1 audio support over TOSLINK optical audio. Finally mine is doing more than just EyeTV recording and transcoding to MPEG 4 for Apple TV.

For years I had been plotting to use my G5 in this capacity but the problem was the video connection. I tried an adapter to go from DVI to component, as my TV’s best input is component (too old for HDMI), but despite reported compatibility with my video card, I could only get 800 x 600 resolution. Then my friend pointed out the obvious: stop striving for the pinnacle of video quality in favour of something that actually works, and get Apple’s own DVI to Video adapter. Instant solution. Now I’m living the dream.

It hasn’t replaced my Apple TV, which is still the keystone of my entertainment system. I have found that it is notoriously difficult to get good results in converting DVD to MPEG 4, so I’ve limited this process to TV only, for which the benefits of fully tagged separate episodes outweigh any slight loss of quality. Considering that a movie can be stored on a hard drive in the exact same format, and thus with no loss of quality, it is worth keeping movies in this way. I use Front Row, part of Mac OS X 10.5 “Leopard”, as my interface to the movies.

To save space, and as the movie itself is the main thing you will want to play, I extract the movie itself from the DVD and discard the rest. I have used MacTheRipper to rip as “main movie only”, but it produces lousy results (often crashes after ripping and the movies crash DVD Player if fast-forwarded), so I have started to use a Windows app, DVDFab Decrypter, exclusively. This app is stable and produces error-free rips. Most impressively, it also overcomes a lot of copy protection that MacTheRipper can’t cope with. Examples: Garth Marenghi’s Darkplace (ARccOS copy protection), The Dark Knight (Warner deliberately “damaged” the disc to prevent copying). The result is a separate folder for each movie containing a VIDEO_TS folder and sometimes an AUDIO_TS folder as well. In this movie folder, put artwork for the movie from your own scans or the internet. impawards.com is one of the best sources. The image file must be called Preview.jpg (case sensitive). Front Row uses this file as artwork to illustrate the movie. It interprets a movie folder as a discrete unit, as if it were a single file with embedded artwork.

I store the movies in the following subfolders in the Movies folder in my local account:

  • Movies: For movie-only movies.
  • Music Videos: Even though I rip all music videos for iPod so that I can take them with me, some DVDs warrant the respect they deserve in terms of video and audio quality, like concerts. This folder houses the more quality-critical DVDs for home viewing. The folder structure for this folder is Artist/Title. The Title folder is the DVD folder itself, e.g. ~/Movies/Music Videos/Flaming Lips, The/UFOs at the Zoo.
  • Short Films: Some DVDs consist of a number of short films, like Wallace and Gromit. I rip the films separately and put them here.
  • Special Features: When I buy a DVD, I rip the whole of a bonus DVD for convenient access. I delete the DVD folder when I’m finished with it to free up space.
  • _Spillover Video: This is actually an alias. I have 2 x 320Gb drives in the G5 but this is not enough. As a temporary measure, I am using some space on an external FireWire drive on my other desktop. Simply mount the drive as a share, then create an alias to the spillover movie folder in the Movies folder in your local account. The share will be mounted whenever you boot. Of course, the other desktop must be online to be able to access that content. When 1Tb drives drop in price, I will buy two and replace the two 320Gb drives currently in the machine.

There is a caveat with Front Row: If you put a series of movies into a subfolder, such as Dirty Harry, the folder will appear at the bottom of the list. There is no good reason for this, but you might not think to look at the bottom for a movie series. An alternative approach is to rename the movie folders with a prefix, such as Dirty Harry 1 | Dirty Harry, Dirty Harry 2 | Magnum Force, Dirty Harry 3 | The Enforcer, etc. I use a pipe character | instead of a colon as the colon is a reserved character in Mac OS X.

Also, any folder starting with The, A or An will of course be incorrectly alphabetised. I put the article at the end, e.g. Golden Compass, The.

To control Front Row, I use Leopard’s screen-sharing feature with my laptop, then navigate using the arrow keys. This makes the laptop hot as it’s constantly refreshing the sharing window, so I tend to quit Screen Sharing once I’ve got the movie going. I’ll have to get a remote for playback. You can’t totally give up a keyboard and mouse as you need to be able to do operations like copying files, trimming the length of EyeTV recordings, etc. Sharing the screen is perfect because you don’t have to supply a keyboard and mouse for the machine.

In addition to running Front Row, I still use the machine to record TV with EyeTV, but I no longer have to transcode for Apple TV. It’s a revelation to simply play a recording. Sometimes I start watching it before it’s finished recording. Sometimes I even watch live TV!

There’s a lot to be said for the movie server. An older machine with plenty of storage makes a great complement to Apple TV, which can concentrate on movie rentals, TV shows, music and podcasts.

Anamorphic Video on iPod

26 November 2008

I’ve been experimenting with anamorphic video. I read after the the 2007 models came out that they supported anamorphic video, so the maximum matrix of 640 x 480 pixels can be used to squash a widescreen video with an anamorphic flag, so the iPod, iTunes and Apple TV would interpret it as roughly 855 x 480 pixels. Obviously the iPod would have to shrink this to 320 x 160 or so for its built-in screen.

Problem is, the results are disappointing. These two screenshots are from the same content and the exact same frame, Lemon Jelly’s ‘64-’95 DVD:

'64-'95 DVD (720 x 400)

Lemon Jelly: '64-'95 DVD (720 x 400) (Click to enlarge)

'64-'95 DVD (854 x 480)

Lemon Jelly: '64-'95 DVD (854 x 480 anamorphic) (Click to enlarge)

Lots of ugly artefacts in the anamorphic version. There are also frequent failures to resolve detail, with the effect that spots of the video suddenly go out of focus for a few frames. Movement has the occasional judder or skip. These are all present in non-anamorphic iPod rips, but far less frequent or noticeable.

I also did test rips of Sigur Ros’ Heima. What’s most disturbing about the results is the fact that the source in both cases is pristine, some of the highest bitrate, cleanest, most perfect DVD I’ve ever seen. If I ripped trash as anamorphic, the effect could only be more pronounced.

So I don’t think anamorphic is for me, despite the unassailable coolness this brings, especially as the increased resolution makes it more attractive for both iPod and computer/Apple TV use, perhaps leading to one version, not two.

Subtle Changes to iTunes 7.7

12 July 2008

In my usual function of pointing out things that other, swifter sites may have missed, here is a 7.7 subtlety round-up.

Firstly, a bad one: With AAC files ripped under 7.7, Lostify is broken. It doesn’t recognise the files as valid MPEG 4 files, so you can’t edit the extended tags such as File Kind, Release Date and Copyright.

Album Art in iTunes 7.7
(Click to enlarge)

Album art in iTunes is magnified to fill the screen, regardless of original resolution. All my 400 x 400s now look huge and blocky. I don’t know if I like this beyond it being a prompt to upgrade my artwork. If the art is oddly sized and low-res, like for this podcast, it’s a little unsightly at full screen. This is from a 1920 x 1200 monitor.

Artwork at maximum size used to go below the dock, but now it doesn’t, which is a nice enhancement for artwork enthusiasts.

Remote

You’ll hear a lot about Remote for iPhone/iPod Touch, but I just wanted to register that it is jaw-droppingly well done. No other company could produce a remote so tightly integrated with iTunes and the Apple TV. The response time between interacting with the screen and playback is instantaneous. If you’ve set up AirTunes with an Airport Express or Apple TV, you can select which speakers you want to use, just like you can in iTunes.

I was playing a video on Apple TV, then paused it, changed control to iTunes on the computer and started playing an audio track, with the output going to the Apple TV using the AirTunes feature. Instead of the Apple TV choking, it simply displayed the album art and track information in the lower-left of the screen, then changed to the audio Now Playing screen. This is very impressive.

So, apart from support for the major features of iPhone/iPod Touch, some small tweaks. I’m not expecting any more, but will post if I do.

Ripping Video Tape

27 May 2008

Great Southern Land
(Click to enlarge)

This is a video tape. Great Southern Land by Icehouse, never released on DVD. What’s a collector to do? It wasn’t that hard to rip, as long as you’ve got the tools.

Firstly, a friend of mine (because his VHS deck was stereo, and mine is mono), ripped it for me by connecting the deck to his EyeTV. He then recorded in real time, producing an EyeTV file that was 720 x 576 (PAL). I then used EyeTV to rip to iPod (640 x 480, 1500kbps H.264/128kbps AAC). This gave me one long iPod file. I used QuickTime Player Pro to cut out the separate videos, tagged each with Lostify and dragged them into iTunes.

The result? Pretty crappy video on Apple TV and the computer. Looks okay on iPod. I’m not overly concerned about the quality because there’s nothing you can do about it. The good thing is that I can now enjoy this content again without endangering my tape through wear and tear.

This process took me back to the ’80s and the positively archaic video technology of the time. DVD truly is a quantum leap forward in quality and usability. Luckily, that’s the only tape I needed to rip. The only other VHS I own is the original Star Wars Special Edition widescreen set from 1997, and there’s no way I’ll ever play it again. It’s purely a collector’s item now.

Don’t Underestimate the Mac Mini

21 April 2008

Last year I upgraded my G5 to improve iTunes performance. As noted in that post, I achieved only moderate performance gains. The G5 was always pretty good at encoding with Handbrake, but now that I have added a number of tweaks to get better quality output, it was taking a very long time to encode video (about 18 hours for a 22-minute TV episode). That’s a little non-viable.

I was impressed that my MacBook Air was ripping video slightly faster than the G5. It’s Apple’s slowest machine, at 1.6GHz. I started to think that a Mac Mini would give me modest improvements on that, and because I appeared to have some hardware issues on the G5 with USB ports going offline, system lock-ups, etc., I decided to replace it now with a Mac Mini rather than wait for the next update to the line.

Given that I have plenty of external storage and an external DVD drive, I decided to save a little money and bought the entry-level 1.83GHz model, with 80Gb hard drive and combo optical. This is the slowest desktop Apple currently produces, so I wasn’t expecting it to be much better than the G5. It turns out that with most operations (opening windows, navigating through iTunes, etc.) it isn’t much different. I was starting to get a little buyer’s remorse when I ripped a TV episode to test it.

I had to check very carefully that it had produced a playable file of the entire episode because it ripped it about 5 times as fast as the G5! I was astonished at the difference, so impressed in fact that I considered buying another one just to rip video. It turns out that the MacBook Air was turning off one of its cores under the load of ripping, thus accounting for the lacklustre performance compared to the only slightly faster Mini.

Of course it comes five years of development time after the G5, so that dampens the surprise a little, but I think this proves that the Mac Mini is a pretty good performer despite its position in the product hierarchy, and you should consider it.

QuickTime Player 7.4 & MPEG1 Video

25 February 2008

Here’s a quick tip that I was pleased to discover. QuickTime Player has, for as long as I can remember, never been able to export the audio from an MPEG1 video file. It can play it fine but if you convert to something else such as iPod, you got a video without audio.

I used to have to use MPEG Streamclip to rip MPEG1 to iPod as it handled the audio properly. Last night, for the hell of it, I tried it with the latest QuickTime Player (7.4.1) and lo and behold, Apple has finally fixed it and I have my video + audio iPod track! Very nice, even though it’s taken many years to come to this.

iTunes 7.6 Subtleties

7 February 2008

Focussed on movie rentals as it may be, 7.6 introduces some subtle bug fixes and welcome behavioural changes, some of which we’ve been asking for for some time.

Bug Fixes

As long as I can remember, iTunes by default used the constant bitrate (CBR) method of encoding, resulting in neat bitrate values such as 128 and 256. The last version of QuickTime was updated to include further bitrate encoding methods. iTunes then dropped the ball and users noticed that their rips now all had varying bitrates, plus or minus the value specified. Apparently iTunes wasn’t told to continue using CBR and started using one of the newer methods. This has now been fixed. Rerip your CDs and your bitrates will be neat again.

Enhancements

Podcasts Option Menu

Something that hasn’t made sense for a long time has now been addressed. Until now you could not sync a number of “least recent new” added podcasts, only “most recent”. This has now been added and it makes things a lot easier. For example, if I download a lot of podcast episodes at once (as is common when I discover a podcast), they would rapidly fill my 4Gb Nano, which is my main podcast iPod. The solution was to uncheck a number of episodes. With “Only sync checked songs” and “Sync unplayed episodes” set, this made it manageable. It adds work, however, as you have remember to check newer episodes as older played episodes come off the iPod. Now I can leave them all checked and by syncing only the 3 episodes least recently added, I avoid filling my iPod prematurely and don’t have to think about it. This is a very welcome change.

You have both the option for “unplayed” and “new”, which seems a little redundant. “Unplayed” means that whether or not a podcast has been started, it does not have a play count higher than 0. “New” means that a podcast has never been started. I guess if you only wanted podcasts that you’ve never played, not including unfinished ones, this would be a usable distinction.

TV Shows Option Menu

Similarly, TV shows now have a new “least recent unwatched” option which finally resolves the stupidity of buying a whole season of a TV show but only being able to sync a certain number of “most recent unwatched” episodes. The focus here is still very much on the basis of only watching an episode once. If you are happy with that, then this solves it right here for you, but if you like to cycle through your episodes, you should resort to my TV Rotation Technique.

Blackadder Series

TV Shows in Album view are now subdivided into seasons, each marked by the album art for the first episode in a season. If you scan the box art for individual DVD sets like myself, this feature vindicates this approach. Looks nicer.

You can now manually manage iPhones and iPod Touches, if you wish. Still not available as drives on the desktop, however.

To Be Addressed

Apple TV does not support these new sync options but it is reasonable to expect that the imminent update will address this.

Unfortunately, you still can’t make a smart playlist select items by Show, as covered in this post. Hopefully this will come. The inclusion of the elusive “least recent new” feature above, at least for podcasts, is very heartening.

I wasn’t expecting anything more than rental support (by the way, this Australian is gnashing his teeth at this being US-only, although it’s not a surprise), so I’m happy that Apple squeezed in some further refinements.

New Music Video Standard

26 November 2007

Yes, I’ve changed again. I follow Apple’s lead. They believe in H.264, so I do too.

The main reason I was using MPEG4 instead of H.264 was an incorrect assumption that 720 x 400 (16:9) was only iPod compatible if the file was MPEG4. I believe I would have tested this resolution with H.264 in the past–I always test–and would have found it incompatible, so I went with MPEG4 instead. Well, I’ve just done another test with four videos and lo and behold, it worked. This means that they upgraded the standard or that my earlier testing was poor. Either possibility is reasonable.

So what does this boil down to? Music videos are now specified as follows:

  • H.264 @ 1500kbps, 640 x 480 (4:3), 720 x 400 (16:9)
  • AAC @ 128kbps

If the source is a video file from an enhanced CD or the web, I don’t get fancy: I open in QuickTime Player and export to iPod. If it’s letterboxed (bane of the video collector’s life), I use MPEG Streamclip to achieve the same result, only I also crop the margins off (QuickTime Player can’t easily do this).

If the source is DVD, Handbrake is of course employed. I start with the iPod High Rez setting, then add 2-pass and greyscale (if appropriate). For audio, you can actually convert 5.1 to Dolby ProLogic II and the iPod will support it. Of course, you’ll only hear the stereo on an iPod, but this is good for using on both iPod and Apple TV, which might be connected to equipment that can support it. It does make a difference and is quite nice to listen to.

Handbrake 0.9.1’s new enhanced chaptering facility, where you can now name the chapters, is a great excuse to rerip video, and I especially like to rip long-form video such as concerts, Enigma’s A Posteriori DVD, Lemon Jelly’s ‘64-’95 DVD, Bowie’s Ziggy Stardust and the Spiders from Mars: The Motion Picture, etc. with the proper chapter markers. Strangely, the Touch, where I play music video the most, does not display the chapter names. If you tap the screen while a video is playing, it will say Chapter X of X, but doesn’t display the name. Apple has been notified.

Don’t muck with the advanced settings. They’re very good for tweaking video intended for the Apple TV or computer, as these devices are tolerant, but I’ve found that changing the slightest setting will prevent the video from transferring to an iPod (see my earlier post on this matter). You have to stick with stock-standard iPod settings to guarantee compatibility.

So I’m going to start ripping my music video again. The amount of work this entails is made palatable by remembering that I’ve got a number that don’t work with the new iPods and of course, my favourite, the chaptering excuse!

I Discover Ringtones

6 October 2007

I’m not a “phone guy” and can’t buy an iPhone here in Australia, so I’ve let all the developments and hoo-hah regarding ringtones wash over me. I did notice an interesting item in Lostify that I’ve just had a chance to try out.

It’s probably been covered before and may not work with the 1.1.1 update, but I thought I’d mention a technique for creating ringtones that I’ve discovered. I should note that it’s a Mac-only solution.

Ringtones Library

As you can see above, I have a number of ringtones that didn’t come from the iTunes Store. I’ve never been interested in using music for ringtones. These are all comedy items, one from the Adult Swim website relating to The Venture Bros., and the others are from the popular Australian national daily radio show Get This with Tony Martin and Ed Kavalee. Here’s the technique:

You must use AAC (.m4a) files, so if your source is MP3, as all these were, use iTunes to convert them first. These all happened to be 128kbps mono, so I matched the bitrate but converted them to stereo in case there are any future incompatibility problems with mono. Here are the settings I used in Preferences > Advanced > Importing:

Ringtones Conversion Settings

Then delete the files from iTunes and take them out of the trash and put them in a temporary folder. I found that if I Lostified from within iTunes, iTunes didn’t refile them as ringtones, so you have to do the tagging outside. Drag all these files to Lostify 0.7. You can change all the tags you like, but this is the important one, File Kind:

Lostify 0.7: Set Ringtone File Kind

Apply this change to all your files (use the padlock next to the field so you don’t have to select it each time), then drag the files into iTunes. iTunes now sees them as ringtones and they will appear in the separate Ringtones library (you may need to turn on visibility in Preferences > General).

The Ringtones library behaves a little differently to the other libraries:

  1. You can’t drag these into a playlist.
  2. You can’t play all sequentially. If you play one, it will stop after finishing rather than starting the next in the list.
  3. You can’t use Album or Cover Flow views. You can tag ringtones with artwork, however.

So there’s a solution to create ringtones. Whether it works with an iPhone is questionable. I’d like to know if anyone using this technique finds success. For myself, it’s all a bit useless because I don’t have anything to use these with, but I enjoyed the opportunity to organise my ringtones into a separate library. Prior to this, these were in my music library, and of course, they aren’t music. It’s like when audiobooks were separated out into their own library. Much better organisation.

Update 15 Nov: With the advent of 1.1.2 iPhone and iPod Touch, it seems that you can easily add ringtones 30 seconds or less in length by renaming a .m4a file as .m4r and dragging into iTunes. I didn’t know that ringtones had a different extension. I still think it’s a good idea to Lostify them for completeness.

Video for the New iPods: Compatibility or Quality?

5 October 2007

The type of content I’ve most enjoyed on the Touch so far is music video. I’ve filled mine about 75% with music video which I watch at work. As I have 414 separate videos, I’ve been rotating them through and one thing has become clear: compatibility is more important than quality, especially if the prime target for viewing this content is an iPod. I’ve just had a batch of MPEG4-encoded videos, all of which played on my 5th-Gen, fail to display video on playback on both the Touch and Classic. Audio is fine, just no video. I think this is because I used to push the envelope, encoding at 1500kbps MPEG4, which is the highest MPEG4 video bitrate the iPod can support, and also because I made 16:9 videos 720 x 400 pixels instead of the iPod standard of 640 x 360. Result is incompatibility or, at best, borderline compatibility.

So I’ve made the decision to make every music video iPod-compatible. It will result in lower-resolution 16:9 videos but honestly, I can’t be bothered trying to push the envelope any more. I’ve got too much on and I’ve been enjoying the iPod quality. QuickTime Player or iTunes will convert a non-DVD video between 320 and 640 pixels wide into a H.264 video with the same resolution. Handbrake 0.9’s new GUI access to the command-line parameters gives much better results. The new chaptering feature adds another reason to redo your long-form video.

So that’s my advice to you. This of course applies to any content targeted at an iPod. I still rip DVD movies and TV Shows at a much higher quality because they are aimed at Apple TV.
