What steps will reproduce the problem?
1. Start Tony Hawk's Underground with either the D3D or OGL plugin running at 1920x1080

  1. Start a cutscene or begin skating
  2. Begin dumping frames

What is the expected output? What do you see instead?
The video is expected to play back at 60fps, the game's native framerate. Instead it plays back 4x as fast, requiring the video to be slowed down to 15fps in order to correct the speed.

Dolphin version with the problem? Other Dolphin version without the
problem? r6316

32-bit or 64-bit and any other build parameters?

OS version and versions of tools/libraries used?

Please provide any additional information below.
The effect is still present when running at 800x600, but it's not as bad. I can slow that recording down to 45fps (75% speed) to match the actual game speed. This seems to be less of a problem when running at 800x600.

Nevermind, something fixed the issue at some point or another. Please disregard.

Must be related to issue 4064, which was fixed by r7131.

Darn, upon further inspection of the cutscenes the problem still remains. Use this 100% save to get to the cutscenes I'm talking about.

Start the game and continue career mode. Pause the game and change the level to New Jersey, if you are not already there. In the pause menu select options, then view cutscenes. Strangely the cutscene that plays back at normal speed when recording is the first one in the list, "New Jersey Level Overview." The problem occurs with the second scene in the list, "Muska Demo." When not recording, the scene plays back fine. Once you start dumping frames, the issue immediately returns, as if the frame rate is increased by 4x. If you stop dumping frames before the cutscene ends, the speed returns to normal (although the audio will still be off because of the change in frame rate). Im assuming this happens in other scenes too. The actual frame rate remains at 60fps in both gameplay and the cutscenes, so no real framerate change when selecting one from the list. This issue remains in the latest build.

Anyone willing to try this? Anything I need to provide?

Here's a FIFO recording of a single frame captured when frame dumping was active.

Is this issue still valid?

I will test again with version 4.0.

A current development build would be preferable.

I was unable to determine any problems.
