Possible to use sRGB as mp4 colorspace? I have an mp4 using h264 that i'm using in the background of a website. It has to blend in with the background image. I've already created ogv and webm videos for firefox and chrome and these work fine but the mp4 for safari doesn't blend properly. The only difference i see in the files is that the ogv, webm and original mov are all in sRGB color space, but the mp4 is in SDTV NTSC Y'CbCr. I've tried lots of different exporters but the mp4 is always in this colorspace. How do i get the mp4 in sRGB colorspace?

You are currently probably using the Rec. 601 color space for SD video. Encode your source footage in the Rec. 709 color space.  It's the color space specified for HDTV and comes sRGB quite close.
If you need higher color accuracy you can use the Rec. 2020 color space which exceeds the sRGB color space by far. Though compatibility may not be given everywhere with this color space.
