FFAStrans forum

Hello all,

I need to batch convert some video files to ffv1.mkv. I have successfully done this using a Custom FFmpeg node in FFAStrans but now need to modify the parameters of the FFV1 encoding.

I have tried entering the following in the following in the FFmpeg options in the Custom FFmpeg node:

-c:v ffv1
-level 3
-coder 1
-context 1
-g 1
-slices 24
-slicecrc 1
-c:a copy

but each time I try and convert a file, the status monitor gives an error: "Encoding: at least one output file must be specified"

Any help would be greatly appreciated!


Many thanks

James

Hey James,

welcome to the Forum and thank you for using FFAStrans!

Personally i prefer a cmd executor over custom ffmpeg processor because it limits me far too much and it is kind of hard to debug but i tried it out and didnt find any issue using your parameters:

Hello emcodem, thank you for such a quick response!

I have now tried laying out the commands all on one line as you did and I have success! It was my formatting that was wrong.

Thank you ever so much for your help.

James

Not a problem James, feel free to throw at us whatever you got
