My way of making videos is to record them with OBS, open them in movie maker to speed them up x14, render them out and then put them into Sony Vegas 12 to completely edit, render it out again using SV12, then reopen the file in Movie Maker to re-render, only because SV12 gives out ridiculous file sizes for .MP4's (1.5GB+) and re-rendering them with Movie Maker is very fast and the output files go down to a manageable 400MB or so (so I can upload them to youtube in a reasonable time) 

But an issue I've ran in to is every video I save with Movie Maker gets a light, but very noticeable pink tint to it, compared to the correct colours sony vegas 12 gives me, and the multiple re-rendering I have to do with Movie Maker just seems to be layering the pink tints onto each other over and over making it even worse.

I've tried using different settings to save videos, tried making custom save templates, messed around with various BPS, made sure I have no effects on the video clips (which I don't), checked MM's options, etc. etc. etc., and no it absolutely is NOT an issue with my monitor.  Nothing I do is getting rid of this hideous pink tinted colour, which is especially noticeable on greys.

Is there anything I can do about this? It's costing me a lot of time and patience and I'm just about at my wits ends with it. Thank you for any help. I only installed movie maker very recently so I can only assume I have the most recent version.
