Description

Just using transmageddon to rotate some videos (damn smart phones are not so smart sometimes), when using the original format for my videos (MPEG4 audio:AAC video:H264) the last couple of seconds of the video freezes (sound is fine) but when converting to OGG (vorbis/theora) the video comes out perfectly. Tried a few tests all on my same computer, all came out the same results.
