HEVC and AVC not honouring SAR setting
« on: December 31, 2017, 08:02:10 AM »
When processing a PAL SD Widescreen video,
Avidemux ignores the SAR setting in the Output1 tab of configuraion,
regardless of whether the predefined PAL SD WS setting is used,
or whether the SAR is manually entered as 64:45.

Here is a sample input file:

The problem has been around a long time.
I have tried the latest nightly but the behaviour is still there.

Regards,
RJ

From a quick glance at the x265 plugin code the sar_width and sar_height parameters are set. Are you aware of the ability to set pixel aspect ratio at the container level in the configuration of the MP4 (only in the nightly) and MKV (in the release as well) muxers?

That looks good - I'll use that instead.
Thank you.
