I use an Easy Cap capture card to record and I was using it to record. I looked at how the video came out and didn't like it. So, I wanted to redo it. I go to start recording, but no video was coming on the Virtual Dub screen. Please help me!!!

Thats not a VirtualDub bug probably, more likely a case of missing
codec or input plugin.

See here, or navigate to the List of Input Plugins thread in the Filter Development forum:
http://forums.virtualdub.org/index.php?act...=ST&f=7&t=19488

Not familiar with Easycap, but most USB-based capture devices are
marketed as being able to record from DVD, hence you are probably
needing an MPEG2 decoder which I don't think comes packaged
with Virtualdub by default. Failing that its probably H.274 mp4.

There are a variety of input plugins available for Virtualdub,
I'd suggest downloading at least a few as once you have
a few installed you can select which you want to use when
opening a file by using the drop-down box for File Type and
selecting which filter you want to use.

In my case, I added the ffmpeg input plugin, and
the Direct Show input driver, and these handle most
files, but there are specific MPEG2 and MP4 filters
as well.

Obviously, some of these may not work without
ffdshow installed, which are a compact, highly
configurable set of direct show filters that
compliment multimedia players such as WMP,
MPC-HC, etc.

While I'm at it, MediaPlayerClassic-HomeCinema,
in case you're still using MS's WMP which
gets increasingly frustrating to use with each
version:

The other thing it can be of course if you're trying to directly capture using VD
rather than just using it to edit the files from easycap, is that alot
of the USB-based devices don't show up as eligible capture
devices in Virtualdub I don't think.

You're probably best capping in the program that comes with
the device, then re-editing it to look better in Virtualdub using
the array of filters for fixing brightness, saturation, contrast,etc
that it comes with, or which can be added on.
