Video Editing Stuff

(...if you don't speak penguin or overgrown-cat (OSX), then go read elsewhere)

This is the beginning of a section on video. I learned some things I know I'll forget, so here we go:

There are notes on:

Axel Olmos, at AVS Forum, has put together a very useful piece of software for those of us who use Sony camcorders. However, he wrote his software for an earlier Sony camcorder. I'm using the SR-10, which is an HD camcorder that films in 1080i. The problem here is that the SR-10's files have a higher resolution (1920x1080 vs 1440x1080, apparently). Axel's script assumes the resolution to be 1440x1080 (probable he has no documented/reliable way to pull it from the m2ts file), and as a result, higher-res camcorders just show this nasty shifting green screen in place of the expected video. I seemed to recall that my camera films in 1920x1080, so I tried plugging that number into Axel's script in place of 1440x1080, and it worked perfectly.

mencoder $videofifo -demuxer rawvideo -rawvideo w=1440:h=1080 -aspect 16:9 -ofps 29.97

should be changed to:

mencoder $videofifo -demuxer rawvideo -rawvideo w=1920:h=1080 -aspect 16:9 -ofps 29.97

Given that the SR-10 has 2.3 effective megapixels, but the SR-11 and SR-12 are both at 5.6, it's possible that owners of this camera may still have to adjust their resolution settings.
