Codec for Dxtory and sony movie studio platinum 13?

[MarkSkoog]

So I use the lagarith lossless right now and the color comes out really dark when I render in movie studio and I have try ed everything but change the codec. I recorded with the original dxtory codec before it worked but now it's not. So do you have any other recommendations I heard the Sony yuv codec is good but can't find download link

Thanks,
Mark
