+1 I go it. The brightness is on the visual effects tab, right? It didn't seem to help much, and I can't find any contrast. Any other suggestions?

@Mawg, that is correct. I do not think that it is possible to change the contrast.

@Mawg, I added another option to use the old WMM 6.0 (vista) and custom effects to change the contrast. I edited the answer above.

<p>I've used <a href="http://www.virtualdub.org/" rel="nofollow">VirtualDub</a> (one of the open source tools) with some success for just this.</p>

<p>It's not trivial to use, and I'm afraid I don't remember the exact settings, etc., but there are plenty of tutorials/explanations around the web.</p>

+1 I am trying it now, but when I try Video/Filter, it complains "couldn't locate decompressor for format Xvid" and says it requires a "VFW compatible compressor".  I D/Led from http://www.xvid.org/ and it looks good. I will check it out & get back to you. Thanks

<p>The title says it all. My video is too dark. I Learned how to avoid it next time (after the horse had bolted).</p>

<p>Is there anything I can do to lighten it up? Preferably freeware and not to complex. THe video is .AVI format</p>

<p>[update] Windows 7 pro (and I am wondering whether brightness or contrast is the way to go (ans if some magic s/w has an "auto" feature))</p>

<p>Thanks a 1,000,000 in advance</p>

I've used [VirtualDub](http://www.virtualdub.org/) (one of the open source tools) with some success for just this.

It's not trivial to use, and I'm afraid I don't remember the exact settings, etc., but there are plenty of tutorials/explanations around the web.

**Windows:**

[Free Windows Live Movie Maker](http://windows.microsoft.com/en-US/windows-live/movie-maker-get-started)

The problem with Windows Live Movie Maker is that there are limited effects and no way to create custom effects. However, Windows Movie Maker from Vista (i.e. WMM 6.0) does support custom effects, etc.

[You can download WMM 6.0 for Windows 7 here.](http://movies.blainesville.com/p/wmm-60-on-windows-7.html)

[Blaine also provides an extensive list of add on effects here.](http://movies.blainesville.com/p/movie-maker-add-ons.html) Which includes contrast effects to increase the contrast.
