I've had some experience with gtk-recordMyDesktop, but after I switched from a 32-bits desktop pc to a 64-bits laptop (Ubuntu 10.10), RMD started performing badly: The last part of the captured video does not show up in the final ogv video
I tried ffmpeg using this and many other guides, without the expected/promised result. You're claiming a zero-quality loss, although I experience the opposite: see attachment.
The upper part of the screenshot shows the original sample, the bottom part shows the result after capturing: A very perceivable result. The colors are different, and some particles are faded.
How can I capture a part of my screen
without any loss in quality? I want to edit the captured screen using Kdenlive, then upload it to YouTube (using h.264).
I used the following code:
Code:
ffmpeg -f x11grab -r 15 -s 768x512 -i :0.0+810,55 -vcodec libx264 -vpre lossless_ultrafast -threads 0 /tmp/ffmpeg-tests/out.mkv
I tried all possible vpre options and over twenty file extensions, yet no satisfying result. Could anyone help me with solving this extremely annoying issue?
