It wont. H.264 video stores the aspect in a NAL attached to each video frame. We do not have the ability to edit NALs in VideoReDo. So when you save an H.264 file with the aspect changed the aspect is only applied to the NALs if you do a full recode. For MP4 we do set the MP4 header to the selected aspect, which is what you're seeing in MediaInfo. The video header "original aspect" is still 4:3, but the container has been set to 16:9. If you were to save to a container that doesn't support aspect at all, like TS, then it would not change at all. You could set to 16:9 and the output would still be 4:3 unless you did a full recode.And what the bug described in posts #16 and #17. Will be fixed?
- When I fully reencode pure 16:9 mpg file to mp4 file and in profile is additionally set Aspect ratio: 16:9 then in player MPC-HC is in properties showed "Video: MPEG4 Video (H264) 720x576 (71:40) 25fps 2519kbps [Video]". Why is not 16.9? 16/9 = 1.777777... but 71/40 = 1.775.
