I was trying to encode red one r3d-files (4k, 24p) as mpeg2 1920x1080p24 (default settings). However, the mpeg-video was jumping (looked like repeated frames, but why? it is the same frame rate. The audio was messed up to). When I rendered the clip as quicktime-video, everything went well. When I encoded this quicktime-video (photojpg, 1920x1080p24) as mpeg2, the mpeg2-video was messed up in the same way. Are there any known issues with mpeg2-encoding with adobe media encoder/premiere cs5? Or what am I doing wrong?
