I just might have to start watching the Colbert Report.
Any Video Converter, when converting any video with sound, causes the resulting compressed video to play once with sound and then a second time (in the same video file) without sound. The second playthrough is identical to the first, essentially doubling the video length and file size.
The diagnostic process shows:
If Disable Audio is set to Yes, the bug does not occur. (You get a single playthrough of the video, but no sound.)
Disable Audio set to No should leave audio intact. Video playthrough should occur once per file (barring auto-repeat settings on the player.)
Disable Audio set to Yes works as expected, but Disable Audio No causes the expected video to be followed by a copy of the same video without sound (within a single compressed file.)
I did this and one of the games I’m playing right now got a 20fps improvement: It used to fluctuate between 40-60fps, but after disabling Core Parking it went to a solid 60fps.
