I don’t know if that reply was telling me it would cause my problem or wouldn’t. Entertaining nonetheless. That kind of stuff is beyond my knowledge.

To be honest I sort of gave up and attributed it to some sort of user error in my recording process. Since this issue is common with rendering an MP4 in vegas but not widespread it has to be something I’ve done wrong outside of vegas.

Either that or most people don’t notice the minor color shift. Which I doubt.

My video editing knowledge is too limited to correct the colors inside vegas, that would take entirely too much trial and error for me. There isn’t much more I can try on my own.

So does anyone know if recording in RGB colorspace then rendering an MP4 as YUV could cause this color shift?

I believe I made some improvements by using a new recording codec that records YUV420 instead of RGB.

It still isn’t exact color though. Im running out of ideas here.

Edit: Scratch that. Recording with anything other than RGB produces cloudy video that looks nothing like the original.

Would it help to upload higher quality screenshots that haven’t been modified by imgur?

Alright so the video preview for the original footage in Sony Vegas looks exactly the same as the original footage. Perfect color. No darkness. Exact copy.

As for previewing in another player, I’m not sure how that would help, both videos are being viewed in the same player, so unless VLC displays video differently for each codec (one for raw video and one for mp4 compressed) then it wouldn’t make a difference.

Edit: I tried previewing both videos in another player just in case, the rendered video was darker there too. So it isn’t the player causing the problem.

Second edit: Here is a picture of the scope for my rendered video for comparison to the first one i posted of the original video.

Also, I dragged my rendered video into the timeline to compare it to the original in the vegas preview, it appears darker there too.

So my original footage has the wrong levels? I’m confused here. The scope I uploaded was from my raw video before rendering.

Don’t forget that I’m barely above amateur at this video editing stuff. All those numbers are like a foreign language to me.

I’ve applied both RGB filters and they didn’t fix it, they just changed it to a different color.

I’ll check into the preview differences after this rawcap finishes compiling, its slowing my hard drive down too much to mess with vegas.

Here is the scope thing for the first frame of my original video. Wasn’t sure how to upload so it looks like I screwed up.

As for your treatment, it is really hard to tell with small screenshots. Even with 5 MB fullscreen screenshots it can be difficult to see the difference between the original video and the rendered video. But it is there.

If you want to tell me what you actually did, I can try applying it to a render and see if it produces the color quality that I would like.

I’m not exactly a vegas pro, so I’ll be surprised if I can do what you want on my first try.

I’m not sure how I’m supposed to show you what I want to achieve, because I’m unable to get vegas to do what I want. The most I can do is give you scopes of the original video, if that will help.

Scopes are new to me, can you describe what you need me to do with a little more detail.

I’ve tried rendering with each of those settings changed. 8 bit, both 32 bit options and both compositing gamma options.

The end result is always different than my original video file. When I say original, I mean the original file that I recorded, not the preview window.

To be honest I don’t think there is anything more I can try. I’ve tried changing every setting and rendering again. I’ve rendered 20+ different files, not a single one of them had identical color.
