A single breaking of the aspect ratio of 16:9 to 0.707 #239

The source video has an aspect ratio of 16:9, after interpolation the aspect ratio becomes 0.707 and the picture is stretched. Not critically, in player can manually select 16:9 or SAR aspect ratio. I use RIFE 4.6 NCNN/VS with a factor of x2.5, since the video has exactly 24 fps, saving in the h265 NVENC codec, fix scene is disabled. There is an option that it's actually not 16:9, but 1.37:1 aspect ratio, I don't know https://drive.google.com/file/d/1IUsRxRcLbHTso894JXT3uyh9kgpwFpfA/view?usp=sharing, https://drive.google.com/file/d/1nRTVd2hosvhR9Cl6iTvX-cyS6uCF28lq/view?usp=sharing image

Same problem here, from 16:9 to 0.672 Flowframes 1.40.0 H265 / 10bits image

Using this one, I'm able to have a correct aspect ratio ffmpeg -i input.mkv -c copy -aspect 16/9 output.mkv
