Hi,
Just testing Avids Jpeg 2000 codec for the first time and I get metadata back from FFMPEG like this.
Metadata:
product_name : Avid Media Composer 8.2.6
company_name : Avid Technology, Inc.
timecode : 03:43:19:20
Duration: 00:00:07.36, start: 0.000000, bitrate: 61549 kb/s
Stream #0:0: Video: jpeg2000, yuv422p10le, 1920x540, SAR 1:2 DAR 16:9, 25 tbr, 25 tbn, 25 tbc
So this must be wrong right?
Maybe not - 10bit JPEG2K file sizes are approximately HALF of 8bit 50Mbit/XDCAM MPEG2 - which would work out logical if the material is indeed 1:2 SAR with a resolution of 1920x540. Half the info was trashed.
If the Media Composer JP2K was 1920x1080 - then I would expect files at roughly the same size, as the codec is more advanced it can logically pack 10 bits of information into files at roughly the same size as 8bit XDCAM.
But these files are 1/2 the size and Media Composer reports 10bit 1920x1080 - what's going on with JPEG 2K in MC? where are the specs?
