I'm using ffmpeg as a standalone at work where many people call the same script to record their desktops. When we started 1280X1024 was the favorite among all users. I'd like to set preferences so that we all capture, edit, and render at the same resolution. The output will be streamed internally in our own video player.

Here's the capture script:
ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -r 24 -s 1280X1024 -i :0.0 -vcodec flashsv -threads 0 /tmp/desktop_recording/${USER}_recording_$datestamp.flv


Is it possible to:
A. Set the record monitor's screen grab function to call the same script?
B. Set the project to the same resolution?

I see profiles here:
/usr/share/mlt/profiles/ > ls
...
hdv_1080_25p
hdv_1080_30p
hdv_1080_50i
hdv_1080_60i
hdv_720_25p
...

I just don't know if I need to create a custom profile in addition to other preferences. Again, I'd want to capture, edit, and render at 1280X1024.

Thanks!

Use the Settings menu. You can make project profiles and adjust capture settings in there.

Thanks! Works for setting project, still not able to capture at the resolution from within kdenlive. I can still use my ffmpeg script for that, though.
