In my continued quest to seek out new formats and new codecs, I thought I’d have a go at making some mp4 files. I still can’t seem to produce sensible small Quicktime movies (although I think I’m getting closer). However, MP4 is supposed to be the new “standard” – the video lingua franca and equivalent of MP3 in the audio world. Most importantly it’s the format of choice for the new PlayStation Portable (PSP).
Luckily I found a neat piece of free software called PSP Video 9 which has a good stab at taking any old video file and encoding it into a PSP-compatible MP4.
My first try with the software ws reminiscent of my QT efforts – a file that was over three times bigger than the equivalent WMV. After a bit of tinkering with frame sizes and rates, and limiting the bit rate, I got an MP4 that’s only a shade bigger than the WMV, and roughly similar quality.
Now I just need to work out how to:
- script the software as part of my videoblog “workflow”
- get two RSS feeds on my site with the same posts but different enclosures
