Increasing Brightness/Contrast in Video?

[Westly32]

Is there a way to increase the brightness or contrast in source video material before it's authored to dvd? I've run into a slight problem. After burning some video to disc, playing them back on a stand alone dvd player, the picture quality is decidely dark...Not so dark as to be unwatchable, but annoying to me at least. Turning up the brightness on the tv is a pain, because you then must set the brightness level back afterwards. Playback of source video is fine on the pc. Suspected it was the media I used-TDK DVD+ 8x, but other projects created are just fine.
So, is there any software preferrably free-yes, I'm cheap...that allows you to adjust the picture quality?

How did you prepare your files? In TMPGEnc you can correct the brightness,colour etc. before making the final mpeg2 file.

I use TMPG DVD Author 3 with Divx. This version, appears to not have those kinds of controls...drat.

Use an Avisynth script and feed into TMPEGEnc,

avisource("C:\path\to\file.avi")
tweak(bright=20,cont=1.1)

Where brightness is somewhere between -255 and +255, default 0, and contrast between 0 and 10, default 1.

I was referring to TMPGEnc Plus.It is better to use TMPGEnc Plus(for preparing your DVD compliant files) before authoring in TMPGEnc DVD Author.

Ok, I always get those confused when reading threads. I do have that, and will bang my skull on it this weekend...

Thanks.
