View Full Version : How To Make An Avi Brighter?

Hope this is in the right place. I've had a look around and I can't find a better seeming place, considering I am such a newbie and all.

I have an avi file I want to burn to dvd but it is too dark for my liking.

I've searched the web for clues on how to lighten it up and haven't got any help that has really enabled me to do it.

Directed to different software packages that would enable this I either discovered I couldn't find how or they enabled it only for playing and not for keeps - so's I could then burn it.

directed to an avs script for virtual dub I found virtual dub gave me an 'import filter error (unknown) (80040154)' and when I searched on that I found a thread (elsewhere) that suggested downloading 'gordian knot' (a codec bundle) would fix it.

That thread was from 2004 and the gordianknot I found to download was also a 2004 version and that all worried me a bit but I went ahead anyway, sticking all sorts of things on my computer that I don't know that I want really (xVid, etc...).

And in the end.... it didn't make any difference.

I should make clear that import filter error came from the .avs load and the .avs I was trying to use is like this:

# file: amga1.avs
AVISource("amga1.avi")
Tweak (bright=50)
LanczosResize(720,480,0,0,576,320)

and I got it from my web searches.

When I load the avi directly into VirtualDubMod not using the avs) I got an error "nothing to output bframe decoder lag" which seems to be a triviality but I just thought I'd mention it.

I'd say by now doing this would be a lot easier than it was in 2004. Could someone please tell me what's the easiest way to d o it?

And - if you think I've done any harm by installing that 2004 codec (and other stuff) bundle please clue me in about that, too.

regards,

ab :)

You're definitely using a lot of outdated software with that bundle. You should still be able to do things, just don't report bugs unless you update the tools individually, especially avisynth. The only other things you need are ffdshow and haali's anyway, along with the DVD tools (quenc/hc and muxman).

More useful help, try using DirectShowSource instead. You won't get the b-frame lag, but it won't be quite as stable either. Or use mpeg4modifier to convert it to a packed bitstream and use avisource.
