Re: [GEM-dev] problem to play movies at normal speed with GEM objects

Ok, thank you for the clarifications Chris. I haven't photo-JPEG on VLC (ubuntu 9.04), i will try later with mencoder or imagemagick. ++

It really depends on the OS and API used to decode the video. Quicktime has similar performance using either Motion or Photo JPEG, and ffmpeg treats them equally well in Windows using FFDShow. I don't know if libquicktime is handling these codecs on Linux or not.

    But it is better to use Photo-JPEG for scratch video for

Use Photo-JPEG for non-interlaced sources and Motion for interlaced. Or deinterlace before converting to Photo.
