Video skips in VideoRedo player

[holygamer]

I watch my videos in real time in VideoRedo marking chapter points as I go. Annoyingly at least once every 5 minutes or so the video will skip ahead a sec or so. Tried the latest Beta but it still has that problem. Is there any way to fix this?

My videos were recorded with the Elgato Game Capture HD at 1080i 25fps, 16 Mbps and they have 128 Kbps AC3 audio.

Is it the same for all your recordings? And do they play correctly in a player, such as VLC?

 

[holygamer]

Yes. Yes they play correctly anywhere else.

I have seen this on some computers where disc I/O is not keeping up with playback.

What are your system specs? OS + SP, CPU, RAM, video card, audio card, hard drive?

Are you using internal, external or network drice?

 

[holygamer]

Windows 7 64 bit SP1
Intel Core i7 2700K 4.2 Ghz
8GB Ram
Sata III Internal Hard Drive is where the videos are located.
GeForce GT 520 Graphics Card
Onboard 5.1 audio

Install and run MediaInfo, open one of the files in it, select View > Text, copy the output and paste it to a reply. It might help the experts to see if there's anything unusual with the recordings.

Here's the Mediainfo report for my MKV. If I edit TS files in VideoRedo the problem is worse. It can still skip ahead a sec or so at random but when I press the arrow key to go back 5 secs it can actually go back or forward by a minute or so!

Try to QSF the file first. See if that straightens out the playback/navigation issues.

 

[holygamer]

Didn't help. There's no dropped frames in the video or anything so there's no reason why it shouldn't play.

Try different drivers and disabling YUV acceleration in Tools>Options>Playback devices

 

[holygamer]

Thanks disabling YUV acceleration seems to have fixed it. What exactly does YUV acceleration do?

Do you have any idea if it's possible to get VidoeRedo to play in double the original framerate so I get a smooth frame rate instead of losing half the motion?

I tried disabling Deinterlace to just get the interlaced source to play interlaced however that caused lines to appear on the video. Why does it do that when Media Player Classic Home Cinema plays the video interlaced without issues?

From the help file:

Use Video Card YUV Acceleration: This option enables causes VideoReDo to request that your video card convert the MPEG signal from its native YUV format to the computer screen's RGB format. Most modern video cards support YUV hardware acceleration. Choosing this option will often result in a slightly better picture quality, and will reduce the CPU usage of VideoReDo by 5% to 15%. If you select this option, but VideoReDo is unable to take advantage of this feature, then VideoReDo will revert, temporarily, to non-accelerated mode. A message indicating this has happened is written to the log file. For slower machines CPUs (less than 1GHz), enabling YUV acceleration can have a dramatic improvement of VideoReDo's interactive response.
Note: If VideoReDo detects that you are editing HD material it will attempt to automatically enable YUV acceleration regardless of this setting. If you have multiple monitors on your system, you might want to disable the YUV acceleration mode as VideoReDo only supports YUV acceleration on the primary monitor. You will not be able to see your video picture on other monitors when using this mode.

When you display interlaced video you are are seeing both fields simultaneously which can give you the "edgecomb" effect. Do a Google search for examples and further explanation.

How do you mean it may automatically enable YUV acceleration even though I disabled it? Does it do it without ticking the option in settings?

I've watched several different episodes of the show I taped. With the option unticked they don't have any skipping problems. However a few more episodes do have the skipping problem. Seems to be somewhat random. They were all recorded with the same settings in the Elgato Game Capture HD.

I've tried alll the different drivers with and without acceleration and I still get the glitches.
