[HELP] Aspect ratio for DVD PAL 16:9 not preserved
#4
Mediainfo reports:
Width                                    : 720
Width                                    : 720 pixels
Height                                   : 576
Height                                   : 576 pixels
Sampled_Width                            : 720
Sampled_Height                           : 576
Pixel aspect ratio                       : 1.896
Display aspect ratio                     : 2.370
Display aspect ratio                     : 2.40:1
About the source, Hybrid uses the 'Pixel aspect ratio' info of 1.896 and converts it to a fractional (256/135).
FFmpeg on the other hand reports:
Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k
Since Handbrake like uses libav it will also detect the same as FFmpeg.
No clue whether it's a bug in MediaInfo or FFmpeg always overwrites the PAR in some cases.
You would have to ask the MediaInfo developer about the discrepancy.

Hybrid does use MediaInfo and ffmpeg for the source analysis, but it normally relies on MediaInfo for the aspect ratio.

Dev versions are in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.
