mp4 file appears lighter
Posted by Ashley Kay on January 15, 2012 at 4:33 amI know mp4 h264 files have good quality, but when I use them in Sony Vegas, the color ends up lighter. What do I do to keep the color as the original file?

January 15, 2012 at 9:47 pmI’m not sure if this is what you’re describing but your problem might be a computer RGB – studio RGB problem. If you don’t have experience with the subject, you can do a forum search for “computer studio RGB”. It’s a common problem which shows up when you have a video format which uses the range 16-235 to represent the video levels and you display in the Vegas preview window which displays the range 0-255. The preview window shows less contrast than the original video. The darks don’t look so dark anymore.
You can get Vegas to convert from studio RGB to computer RGB by applying a Color Corrector filter and then using the studio to computer RGB preset. You can just apply it to the preview window if you don’t want it to affect your video.
But the subject can get more complicated because there’s the issue of whether you should edit your video in 0-255 or 16-235. I have a project which involves two cameras: one is 16-235 and the other is 0-255. That’s why I got stuck dealing with the situation.
But if you’re just doing basic edits from one camera then working in the camera format is probably easiest and you can make the preview window look better by applying the effect to the preview window rather than on your video clips (uhh – events).
