After I have captured a video and begin previewing it to remove commercials, etc. I use the slider to run through it. I am afraid that my moving of the slider smoothly enough, with the mouse, to catch all the glitches, leaves something to be desired, especially the ones that are only a few seconds long. I often use the direction keys to move the slider when editing out such things, but find they move too slow for previewing the entire video. Is there a way to speed this slider 2 or 3 times faster than normal speed. I tried pressing other keys in conjunction with these keys, but to no avail. I would appreciate your thoughts on this.

I can only confirm that by using the slider bar there is always a risk to jump over fragments that are only a few seconds long, especially when the recorded file is large in length. When using Preview - available in some filters - it looks like the slidebar in these previews seems to work more smoothly than the one in VirtualDub itself. Myself, I do not have an explanation for this.

Something that you can do - and test if it can serve you - is, via Options > Preferences > Scene:
- first take note on which position both sliders are
- put these sliders to zero
- confirm by clicking OK (do not click on Save, if you should do then these settings will become permanent).

After that, click on the Scene forward button beneath VirtualDub's sliderbar. VirtualDub should then 'run fast' through the frames.
The speed will depend a little bit of the inputvideo itself (resolution and kind of codec).
Click on Stop button to 'hold' it.

Do not forget to set the Scene sliderbars to their original position, before Save to AVI...

Thanks for your response. I tried out your suggestion and it works very well. Hope someone can look into this in a future version. Thanks again.
