Video File adjust Brightness

Rensin · 25 Jul 2016 at 15:44

Hi,

Looking for some software to adjust brightness/contrast of a video file. I know adobe premier will do this but is a bit over the top just to adjust brightness.

Video files are either .ts, .mkv, .mp4

cheers.

You can't do it without reencoding the video and resultant loss of quality. Can you not just turn down brightness in the player?

Something like virtualdub will do it (though not sure you can open mkv directly in it) - but as above unless you use some kind of lossless recompression (which will make filesizes about 4x bigger than the original compressed file) the quality will be degraded - some of the cleverer codecs can recompress just a brightness/contrast change without additional loss or minimal loss of quality if setup correctly however.

yeah already know the video needs to be re-encoded.

Just looking for editing software to adjust the brightness.
