Techy details

A few technical details for anyone wanting to make their own Twelve Fives vids.

The original video was shot in PAL (720×576 pixels) but as it was shot as anamorphic widescreen, that works out to 1024×576 in square pixels. The podcasted movies are half that: 512×288 @ 25 fps.

For compression, I use and recommend QuickTime Player to compress in H.264 @ 650 kbps. Yes, you can use free tools to compress in H.264, but they look terrible compared to QuickTime, which looks great at that size. To avoid interlacing issues, I turn on Single Field in QuickTime Player’s Visual Settings before exporting. That way, there’s no vertical resampling and no double images.

Why no iPod-friendly video? Well, though there’s an easy Export to iPod with Video option, it produces large files. You can manually produce an MP4 if you play with the settings yourself, but you’ve got to downgrade to QuickTime 7.0.3 to avoid a bug, and be very careful with your settings. Even with all the care in the world, one of my movies still wasn’t coming out iPod-friendly, despite using exactly the same settings as several other movies that worked just fine. Since the audience (you! all of you!) is small and conversion is just a menu option away for those who care, I’m just sending out larger, higher quality movies for now. Let me know if you really care either way.

Audio is original, compressed down to 96kbps AAC to save a little bandwidth. To easily sync the beat changes with 5 second shots, the tempo is set to 96 BPM, which also contributes to the languid feel. Average level @ -12dB, peaks around -6dB, but this isn’t broadcast so I’m not being super strict about it.
