Hello all,
I'm working with kdenlive v19.14.3b app
My PC is not recent and I need to create a video with 2.7k rushes. So I would like to use proxy clip. By default, kdenlive creates proxy clip in mkv with 960p.
I would like to create smaller proxy clip, like 640p. In the kdenlive configuration, I changed to "-vf scale=640:-2 -vcodec libx264 -g 1 -bf 0 -vb 0 -crf 20 -preset veryfast -acodec aac -ab 128k" and clear the cache proxy.
But when I asked it to create proxy clip, it doesn't use my config and continue to use 960p.
How to change this value ?
Thank you.

Project -> project setting -> tab "proxy" -> tick "enable proxy clips" -> click icon "Manage proxy profiles" -> click the "+" to create a new profile with your desired settings.
