I've been toying around with the trial version of Action, and so far I am not happy with it.
The bitrate, even on max quality recording stetings, is extremely low, jumping around less than 10 Mbps bitrate. There is significant loss of video quality as a result.
I tried MP4 (NVIDIA NVENC) and MP4. Both yielded horrible results.
Is there any way to increase the bitrate? So far Bandicam is proving to be better software.
