Difficulty Rendering Video

So, I’m making a short live action clip. I have composited the CG and live action elements, and rendered it all out as frames. There are about 1000 of them.

My issue is this: when I put my frames into the sequencer, along with the audio, the resulting video comes out bright red, unless I set the output type to Quicktime. However, if I set the output type to Quicktime, the audio doesn’t come out in the render.

If anyone knows how to fix the coloration issue, that would be very helpful.

Also, despite looking, I couldn’t find which video formats support rendering with sound. If anyone could tell me, that would also be nice.

Thanks in advance!
