compare encoding with FFmpeg/SVT-AV1 v. 1.7.0 and
rendering with the current CinGG/AOM-AV1 (v.
3.1.1?), I used a medium length 1080i HDV clip (ca.
7 min duration) as input file:<br>

Format I selected "our" Preset "HDV 1080i/25".<br>
The Color model changed from RGB-8 bit to YUVA-8 bit. but I
didn't see it change of geometry parameters. <br>
Still the Canvas size was: Width:1440, Height:1080, W Ratio:1.0,
H Ratio:1.0, Aspect Ratio:16.0:9.0<br>
<br>
If the latter Aspect Ratio is equivalent to FFmpeg's DAR 16:9, <br>
shouldn't W Ratio and H Ratio be equivalent to FFmpegs pixel
aspect ratio SAR 4:3 as in the svt-av1 encoded file?<br>
<br>
Or generic: Would it be possible to automatic get the format
parameters identical to how FFmpeg (FFprobe) read the source
file?<br>
And like SVT-AV1: By default SVT-AV1 will encode 10-bit sources
to 10-bit outputs and 8-bit to 8-bit.<br>
<br>
---------------<br>
<br>
I tested also Cin-GG/aom-av1 rendering of 20081103140154.m2t hdv
file (you used above with ffmpeg.)<br>
The same result, display aspect ratio is 4:3. Actually as soon
the files are saved to disk, Gnome File manager show them
visually like the 4:3 SD icons.<br>
<br>
Could you possibly try to render the same file using CinGG
av1.webm to verify what happends ?<br>
