So we need to split in two files
Removing alpha, can be useful when graphic artist, output file with alpha, but alpha can be "replace" by blending mode (so we can reduce size, GPU bandwith need (specially when using several high resolution layer)) Only keeping alpha : An use, can be to output an HAPQA using Quicktime official plugin (who doesn't support HAP Alpha Only), and keep only the Alpha part. In other words, it's a way to create HAP Alpha Only file Martin _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
