VirtualDub weirdness

PB · Post by PB » Sat Jul 11, 2009 8:01 am

I was just using VirtualDub to convert an MPG2 video to AVI, and opened
Firefox to search for PureBasic. I was amazed to see the links of Google's
search results changing color due to VirtualDub's preview window, which
was in the background. When I then minimized VirtualDub's window, the
color-changing stopped. I restored VirtualDub's window and then opened
Outlook to check my e-mails, and the text of my e-mails were changing
color too! Anyone got any idea as to why this is occurring?

Here's an AVI video of the Google results that I recorded with my camera.
I resized it to 320x240 to keep the file size down to under 1 megabyte:

Here's a still shot of the multi-color links:

maybe due to overlay?

you can check disabling overlay on Optiond, Preferences, Overlay

As already mentioned by buzzqw, you should disable hardware accelleration in the video/preview options. Cause Vitrualdub then is using GDI, which is for shure less fast BUT color accuracy safe. As you never know which YUV-RGB conversion method is used inside your graphics hardware for screen output acceleration.

Okay, I unticked "Use DirectX overlay surfaces" in VirtualDub and it's gone. Thanks!

StaxRip if better for encoding, in my opinion.

> StaxRip if better for encoding

The encoding depends on the codec used. So if I use VirtualDub with Xvid,
or StaxRip with Xvid, the quality of the encoding will be 100% the same.
