Is it possible to use the Vapoursynth Editor with ffmpeg instead of x264 or x265 during encoding?

Yes ;

You just change the executable path to your ffmpeg.exe in the encode dialog box settings , and enter your ffmpeg commandline (without calling ffmpeg) . Y4M header setting is easier because it passes all the script info parameters to ffmpeg , but not all pixel formats are supported by Y4M

I seem to have trouble getting it work, I tried this:

-y
-i -
-c:v prores
-profile:v 3
"{sd}/test.mov"


Or added
-f yuv4mpegpipe

with and without Y4M

Could you make a small example command?


The bit-depth of the video stream is 10

Was there an error message ?

Yes that works for me on Windows ; I tested with a YUV422P10 source.

But I used one line (with Y4M header setting) . It might have something to do with line breaks or escapes for you


-i - -c:v prores -profile:v 3 -an "PATH\test.mov"

Oops, I found the problem, my FFmpeg path was incorrect.
:stupid:

Sorry and thanks for helping out!

-y
-nostats
-i -
-c:v ffv1
"{sd}/{sn}.ffv1.mkv"
This is my FFV1 encoding preset for ffmpeg.
Used with Y4M header.
Note -nostats. It's important to keep encoding run smoothly!
