I use some Mac-based desktop tools to compress videos for my iPod Touch and my Mac’s at home (Mac Mini to HDTV). I’ve found that a little compression never hurts, and some tools need to be doubled-up to get the job just right.For example, below are two screen shots of the movie Oldboy. I converted the DVD* (I own) to MP4 format using HandBrake. using the iPod Touch/iPhone preset in HandBrake, I was delivered a 944.3MB video file. Not too bad, but I think I can do better. Next, I fired up VisualHub, and also using an iPod Touch/iPhone preset, I further compressed the video, resulting in a 498.8MB video file, which if viewed on the iPod, won’t show much noticeable difference in quality.While the desktop quality can be seen in the screenshots (guess which one is half the file-size?), the iPod’s smaller native screen make the smaller-sized video ideal. I get the filesize I want, and the video plays like a dream.Here’s the spec’s for the two compressed videos:HandBrake:File Size: 940.8 MBDimensions: 480 x 208FPS: 29.97Data Rate: 1083.8 kbits /sFormat: H.264 Decoder, Millions, AAC Stereo @ 48.000 kHzVisualHub:File Size: 485.56 MBDimensions: 480 x 208FPS: 29.97Data Rate: 559.37 kbits / sFormat: Apple MPEG4 Decompressor, Millions, AAC Stereo @ 48.000 kHz* Please do not use the tools I mention above to pirate DVD’s or any other content. You are harming the music and video and entertainment industry of profits that - beyond the private planes and bullshit executives can afford - put food on the table of thousands of grunts (writers, grips, makeup artists, developers, designers, interns…) just like you and me. I’ve always been a staunch believer that personal use is fair use, but distributing pirated materials really hurts - and it’s illegal. I wouldn’t put the link to United Hollywood on my blog if I didn’t believe that people deserve a fare share. You won’t get copies of my iPod videos, so please don’t ask. Torrents count, too, people.
