MP4v2 Muxer - Keep or Force 16:9 PAR possible like MP4 Muxer?

[hausl]

Hello,

if i cut an MP4 and use the MP4 muxer i can use in the muxer settings to force to 16:9. This option dont seems available in the MP4v2 Muxer.  Is there any other way to do this with  video and audio set as "Copy" to cut a video loseless?

If i open the video after cutting in MPC with the MP4v2 muxer it seems squeezed but it was not before sqeezed before cutting with avidemux. If i use the MP4 muxer and "force 16:9" it is correct in MPC after cutting.

There are no differences if i open the input and output file and compare them with MediaInfo, but any difference must be, because only output after MP4v2 squeezed in MPC, neither input nore MP4 output aren't squeezed.

Thank you!

EDIT:

I want to use the MP4v2 Muxer because of this: https://avidemux.org/smif/index.php/topic,16217.msg71003.html#msg71003

The lavf based MP4 muxer is long as capable to mux AC3, so this reason is moot. Use the MP4 muxer, no enhancements for the MP4v2 muxer are planned ATM.
