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.

Steps to replicate:

  1. Fraps video (AVI)
  2. Combine multiple segments into a single segment using Windows MovieMaker 7, add a sound track, save resulting video (WMV)
  3. Compress video (WMV) in preparation for upload to Youtube, set “Disable Audio” to No to include soundtrack from WMV into resulting MP4. Convert.
  4. Upload MP4 to Youtube.

The diagnostic process shows:

  • The AVI is segmented, each segment only plays once. Sound is recorded in the Fraps video if Fraps is configured to have sound.
  • WMV plays only once. Sound plays in WMV if the AVI had sound included, or if sound was added with Windows MovieMaker.
  • MP4 plays twice when “Disable Audio” is set to No. Second play-through has no audio.
  • Youtube video duplicates MP4 experience, no surprise there.


  • Output Profile: Video => Customized MP4 Movie
  • Item Name: Auto
  • Output Duration (Group): All left at Default
  • Video Options (Group)
    • Video codec: x264
    • Frame size: original
    • Video bitrate: 10000
    • Video framerate: 30
    • Encode pass: 1
  • Audio Options (Group)
    • Audio codec: AAC
    • Audio bitrate: 128
    • Sample rate: 44100
    • Audio channel: 2
    • Disable audio: No
    • A/V sync: Basic

If Disable Audio is set to Yes, the bug does not occur. (You get a single playthrough of the video, but no sound.)

Expected behavior:

Disable Audio set to No should leave audio intact. Video playthrough should occur once per file (barring auto-repeat settings on the player.)

Actual Behavior:

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.)

UltimateComputers.net Forum – View topic – Disable Core Parking Windows 7 Tweak may improve performance.

In short:

  • Go to Regedit
  • Find this key:- ” 0cc5b647-c1df-4637-891a-dec35c318583 “
  • Within this key, there is a value called: ” ValueMax “
  • This value represents the % number of cores the system will park – the default 100% ie: all Cores are potentially park-able
  • Change the value from 64 (hex; which is 100 in decimal) to 0 so the ” ValueMin ” and ” ValueMax ” are both zero
  • You will have to find the key a few times and repeat the process for each time it is found – the number of instances will depend on the number of power profiles in your system
  • Do a full shutdown and power-off and cold-re-start

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.
