[HELP] Aspect ratio for DVD PAL 16:9 not preserved

[4i4oVi40]

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.

Cu Selur

Thanks for the explanation. So it's a discrepancy between MediaInfo and ffmpeg.

Also, thanks for Hybrid. I have used HandBrake, VidCoder, Shutter, StaxRip, myFFmpeg, etc. However, it seems Hybrid will become my new favorite. It's very comprehensive, yet its default behavior delivers great results. Also, the hover over tool tips (CTRL+F10) are very helpful.
