Before we begin converting your videos, let’s briefly discuss the kinds of videos that your new iPod can play. iPod video specifications from Apple’s website: H.264 video: up to 768 Kbps, 320 x 240, 30 frames per sec., Baseline Profile up to Level 1.3 with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file formats MPEG-4 video: up to 2.5 mbps, 480 x 480, 30 frames per sec., Simple Profile with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file formats That’s a little confusing, but there’s only a few numbers you’ll need to remember for each format. The highest video bitrate with the H.264 codec is 768 kilobits per second. The biggest picture size for your H.264 movie is 320 pixels wide by 240 pixels high, the exact dimensions of your iPod’s screen. Your iPod can play H.264 video at framerates up to 30 frames per second. Every one of the applications that we’ll be using encodes with the Baseline Profile. Your audio needs to be encoded as AAC audio up to 160 Kbps, 48 kHz, and it can be in either stereo or mono. As long as you follow all the guidelines, your movie can be a QuickTime movie or an MPEG-4 movie file. Your other option, MPEG-4 video, supports a much higher bitrate than H.264 video - 2,500 kilobits per second. Using higher bitrates will also create larger files. The result: you’ll have less space for additional songs and movies. The biggest picture size for your MPEG-4 video is 480 pixels wide by 480 pixels high - three times as many pixels than your iPod’s screen is capable of displaying. Your iPod will shrink the picture proportionally so that everything fits on the screen. Again, the iPod can play videos up to 30 frames per second and our audio and file format options are the same as H.264 video. Sponsored link: That’s a tough question. H.264 is arguably better because it offers high quality and a much smaller file size when compared to MPEG-4. However, both formats look quite good when you encode your video at the higher supported video settings. One thing that most people will agree on is that H.264 video takes longer to encode than standard MPEG-4. This means that converting a two hour movie to iPod video can take considerably longer using the H.264 codec (especially with QuickTime Pro’s pokey Export: Movie to iPod video option). Still, I prefer the H.264 codec in most instances.
