Apple Compressor 4 creating blank or corrupted .m2t and .mpeg
on Mar 14, 2013 at 4:16:29 pm

I'm trying to create some .mpeg and .m2t files for a tv station and compressor is outputting blank files or files that seem corrupted.
The .m2t come out blank or perhaps I just can't play them and the .mpeg files have no video and when you try to play them you get a crazy scrambled audio sound.

When I create mpeg2 with adobe media encoder they seem to play back but i'd rather do these batch compressions in compressor- plus I already created like 20 presets for various tv stations.

Any thoughts?

I've updated everything, running compressor 4 and osx 10.8.2

... and this mysterious player is?
Not all players can play all formats.
I'd suggest testing in VLC 2.0.5.

VLC does play the mpeg2's but not the .m2t


I don't understand why some .mpeg's will open with quicktime and some will only open with vlc.
Both are MPEG-2 program stream. Could it have something to do with YUV 4:2:2 Color?

I just want to be able to check the videos before I send them off to tv stations.
Any ideas on how to play .m2t's since they wont open in vlc?

Yup. Quicktime can't even play H.264 if it's 4:2:2 color.

Try MPlayer. Not absolutely sure that'll work though.

FWIW, I use MPEG Streamclip to open and play mpeg transport streams and they play perfectly well – audio and video.
