The files are 1440×1080 m2ts, avc format and I am exporting to format: MPEG-2-DVD / 16:9 / 720×480 / 29.97 m2v and wav audio file
Sequence settings I have tried matching the source and exporting to MPEG-2-DVD as well as having the sequence settings be 720×480 16:9, scaling to frame size rendering then exporting. They both yielded the same results, computer crashed.
