I gave you an exact command to try, but you added "-preset ultrafast -qp
0" which are libx264 options.

What is important is if it works fine in Kdenlive if you're planning
on editing. Some players or older machines may have trouble decoding
1280x720 huffyuv at realtime.

If you simply want to capture the screen and then upload to YouTube,
then:

1. Capture lossless using huffyuv or libx264 lossless mode using the
   examples I gave you in earlier replies.

2. Re-encode this output as shown in "How to Encode Videos for YouTube
   and other Video Sharing Sites":

If your machine can handle it you can skip the lossless encoding and
adapt the settings as shown in the "How to ... YouTube" link to record
the screen.
