Hello everybody out there doing desktop recordings,
On my old notebook with an Intel Mobile processor with 1.5 GHz and 1 GB RAM, producing a screencast is a pain.
I am using a framerate of 15 fps and a value of 2000M for the rtbufsize option.
There is a nice help page by the ffmpeg developers recommending to do encoding after recording, but this does not seem to make a lot of difference in my case (avi encoder).
This page by the company developing the commonly used screencast software Camtasia is indicating that CPU performance might be the most critical bottleneck for recording performance.
I would like to know which hardware would be best to use, but the statements from the two different websites seem contradictory to me: If I switch off encoding in ffmpeg, CPU performance should no longer be the bottleneck for screen capture.
Thanks in advance for your help!

What are you recording with? What is your recorded video format? Is this a ffmpeg question at all? What is your OS? If on gnome have you tried the gnome screen recorder? If on windows have you tried camstudio? I refer only to free options here- but of course if you used camtasia you would not have these questions most likely. – Rajib – 2013-10-23T16:52:52.943
