I’ve been try to combine a watermark overlay with a command that uses yadif. I am just co-writing a Python script which uses subprocess calls to run an FFmpeg command. > This is a bit of a basic question I fear, but searching online hasn’t helped.

Thanks Moritz for the reminder that I must take better notice of the failed approaches I’ve tried already. I need to test this more broadly when I get some more video samples, or generate some with FFmpeg. I was having issues with the ‘ and “ options, but it functions perfectly this way: I see it has an auto mode, but will it differentiate between upper and lower if sensed also? The "yadif=0:-1:1 overlay” suggestion seems to have worked.

Gyan, I am pleased to read yadif only works if interlacing is sensed. Instead of keeping two sets of mezzanine files per digitised file - viewing and production supply - we’re looking to generate a script so that anyone can produce an mp4 on demand from one higher level mezzanine. Our archives have progressive and interlaced (upper and lower) mezzanine files reserved for supply to production houses etc, which aren’t appropriate to issue as viewing copies. The script is designed to take a mezzanine file of ProRes or H264 mov origin and allow trimming, deinterlacing (of just the mov, not the watermark), overlay of watermark png, and make copyright metadata additions for supply to clients as viewing copies for computer review etc. Next message (by thread): Resolving -filter_complex overlay / -vf yadif conflicts in subprocess call Python script.Previous message (by thread): Resolving -filter_complex overlay / -vf yadif conflicts in subprocess call Python script.Resolving -filter_complex overlay / -vf yadif conflicts in subprocess call Python script pittschick at me.com pittschick at me.com Resolving -filter_complex overlay / -vf yadif conflicts in subprocess call Python script
