And if another option is set that'd require a newer version.
Like "-slicecrc 1" will (of course) switch to FFV1.3 (even if resolution 
is SD).

Would it make sense (and be doable) to show FFV1's version somewhere here?
And/or to show a message if something triggered a different version 
(than default)?

Similar to:
"[ffv1 @ 0x5591491a1e40] bits_per_raw_sample > 8, forcing range coder"

FFmpeg is usually very proper in letting one know when certain decisions 
were made automatically.
Would seem consistent IMO.



btw:
I'm also using MediaInfo to check which version of FFV1 is encoded, but 
this information does not seem visible in ffmpeg/ffprobe. At least not 
in the default output.


For example:
========================
Input #0, matroska,webm, from 'delme.mkv':
   Metadata:
     ENCODER         : Lavf58.29.100
   Duration: 00:00:00.04, start: 0.000000, bitrate: 2814 kb/s
   Stream #0:0: Video: ffv1 (FFV1 / 0x31564646), bgr0, 720x576, SAR 1:1 
DAR 5:4, 25 fps, 25 tbr, 1k tbn (default)
     Metadata:
       ENCODER         : Lavc58.54.100 ffv1
       DURATION        : 00:00:00.040000000
