Codec is truly amazing. It takes a lot of proccessing power to encode these files as well as power to decode them but here are some results along with a test file.
This file was encoded at 50% quality automatic keyframing
It started as a 1.89 gigabyte file and turned out as a 7.8mb file. Judge for yourself how good the quality is. It's amazing to me.
This is a 1080p file 30fps.
Equip:
dual 2.5 G5
Seagate 160 boot drive
Firmtek 1e4 external card in slot 4
4 raptors in a zero striped array
Tiger os with qt7 pro
Radeon x800xt Mac
Ramps up slowly to 28fps
Will play backward, random, but it slows down the performance. Every time you change files, it ramps up, same with play modes.
If this could be worked on, Hidef files in H264 would be really space saving.
This is my initial report.
h264 testfile
'ramping' up will be due to interframe compression....this will be impossible to get around, as this will be the way quicktime works.Quote:

suggest you test photojpeg at 1920x1080 at between 50% and 60% by way of a comparison.
photojpeg worked much better than pixlet last time i checked.
I use this codec to send 1080p presentations to my clients and the files when compressed tightly are only about 2mb in size and very high quality.
It's really a utilitarian bandwidth saving codec meant for very tight and high quality encoding but it's certainly not proccessor friendly and takes forever to encode.
The quality is only good when you encode the files with little compression. They still don't look as good as photo jpeg 75. I've also found that you can't do certain things with them such as frame grabs, they turn white. It is a revolutionary codec and has enabled Itunes to deliver movies, TV shows, and movie trailers. I myself own the entire lost series all encoded in H.264.
You can also encode your own movies and put them on your ipod using popcorn.
