Dark Video

PDD · 2007-07-25 18:54:22

Hi Folks, I was wondering if anyone knew how I could brighten up a video? I have a very funny video of a mate of mine doing some classic air-guitar but the video is very dark and its hard to make him out. I know that there is very little I can do and even less if I wish to keep a half decent quality video. I was hoping…

Hi Folks,

I was wondering if anyone knew how I could brighten up a video? I have a very funny video of a mate of mine doing some classic air-guitar but the video is very dark and its hard to make him out. I know that there is very little I can do and even less if I wish to keep a half decent quality video. I was hoping someone here had prevous experience with this issue.

Regards,

Dave

you can brighten it up but it will add noise (grain) as the signal isn't that strong to begin with.

If you don't have (access to) specialist software there is a brightness adjustment option in Microsoft's Windows Movie Maker. Which is free with XP.
Bear in mind that it only exports wmv files which can looks a bit blurry due to heavy compression so be careful setting the quality settings when you export.

Also you should ask in the Video forum:

or perhaps out glorious Mod can move this thread for you.

It can be difficult to deal with video that's underexposed as the more you brighten it the more video noise becomes evident. You will also need a half decent video editing programme such as Final Cut Pro, Avid, or Premier Pro, something which gives you control over your highs mids and lows. First you need to expand your contrast. Switch your video from colour to black and white. Lower your blacks to where they just about touch 0% luminance. This will make any mids you may have appear brighter. Raise your mids as far as you can go without introducing too much video noise. Then increase your highs (if any). Finally to reduce video noise you could add a very very slight blur filter or effect to soften the noise. Finally switch back to colour by increasing or decreasing saturation until it looks alright. This is just a few basic ideas which should make things better, but not ideal.

perhaps the OP could post a link to the video for someone to have a bash at.
