comment:5 Changed 17 months ago by ami_stuff

I installed avid dv codec again (probably some other version) and quicktime
decodes attached "aviddv_dv50_ntsc_progressive_24bpp.mov" file as 720x576,
so I belive that this file may be somewhat broken (due to bug in old avid dv encoder)?

see also "aviddv_dv50_ntsc_progressive_24bpp.png" - this is how quicktime
with avid dv codec decodes "aviddv_dv50_ntsc_progressive_24bpp.mov" file.

(I also attached new samples generated with avid dv codec)
