I mean, I use an animation program, and I render the animation in a .mp4 file
I put this .mp4 file in Sony Vegas for post production, and when I render it, the colors are changed sightly.
Current settings im using for rendering:
These are the settings i've been using thus far. Using 32bit and linear improved the color a lot, but it is still not the exact tone as the source video... what should I change?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Project Properties, pixel format = full range?, that may not work for your video, try to change it the other choice - video levels or 8bit

What video type inside the mp4 ?
What does "colors are changed sightly" mean ? (slightly?) but to what extent ? Can you post a before/after ? how are you determining this (how are you viewing or taking screenshots)
What other types of manipulations are you doing in vegas ?
Vegas only works in RGB. So would expect to get some minor rounding differences if working with YUV sources in many scenarios -
What program do you recommend to check the information within the mp4 files?
The colors become less vivid somehow... im determining this by looking at the source mp4 file and then the rendered mp4 file with sony vegas. I will post screenshots later.
Im not doing anything else. Just rendering it through vegas is causing the change in color.
I will try to find a program that gives me all info about the mp4 files, im not sure if the animation program renders in RGB or YUV. Its called mine imator, a minecraft animation program. -
I got this info from MediaInfo, there is a lot of options in this program so I hope this is enough:

Here is video levels 32 bit:
And here is 8bit:
And as you can see, changing from full range, video levels or 8bit makes no difference. What can I do to make it look like the source one? -
ok I remember now - it's the same as this
https://forum.videohelp.com/threads/379756-Stuttering-preview-in-Vegas-when-using-a-ce...es#post2454685
I use vegas 13 and the decoding pathway gets routed through qt7plug.dll . It's a variation of the "quicktime gamma shift bug" . It was a pretty common bug in the past.
It might be different for the newer "Magix" versions
In theory, you could just re-wrap it to AVI, and it would use another decoding pathway, but it doesn't work for your sample
The solution record in a different format (IIRC there were several options in that program), or re-encode it to something else before using vegas
You can try to manipulate with the levels filter and come close, but it's easier IMO to use a more compatible format -
In any case, what do you think about my settings here?
should i change something? for example, the variable bitrate settings are correct?
