video enhancement software

[joecass]

what's the easiest, fastest free software to enhance brightness/sharpen a 700mb Xvid file ? years ago I tried different versions of tmpgenc, it took forever to enhance a 10-15min video. Alternatives ?

There are filters you could use with virtualdub. I can't name them since I don't use filters but I'm sure others can chime in here.

Also "years ago" doesn't mean anything unless you still have the exact same computer. Each new computer should be much faster than the previous - unless they are all low end models or all bought second hand and out of step with the current gen.

Assuming this is a standard def (720x480) xvid file it shouldn't take forever to enhance it. If it is a high def file (1280x720 or higher) video it might take longer but given the file size you post it is most likely a standard def file.

Is this just for display on the computer?
If so, use something like the VLC player software that has those functions built-in.

Use the older version I linked.

Any encoding is going to lower quality.

Good Luck

I was going to suggest doing it in the player too, but I usually use SMPlayer. I like the filters much better.

With a 700Mb file I've found, in SMplayer, it's usually best to use the add noise filter, then sharpen. I don't believe vlc can add noise ... it sounds counterintuitive, but adding picture noise makes pixelation much less visible. It's done in digital audio all the time. Another name for it is dithering.

However, if you're talking about a feature length film in 700Mb, there's only so much you can do.
