Rendering Mpeg2

I am going crazy trying to render a project to mpeg2. No matter what I do, I keep getting artifacts and blips all over the place. Has anyone had this problem, and perhaps found a solution for it?

Is the problems you are having mainly in dark scenes, during transitions, or during fast motion scenes?? If so, it is completely normal, lots of DVD encoeders have problems with low lighted scenes, fast motion, and during transitions, you get the king of square pixelated stuff going on. The best way to encode stuff like this is with a 2-pass variable bitrate, keeping your target rate around 5-6mbps. That should solve your problem, I don't think Vegas offers the 2-pass option when encoding, but someone can feel free to correct me if I'm wrong. Normally we will use the Canopus ProCoder for this, or our Sonic Fusion system.

CCE Basic at $58 offers 2 pass VBR, but you'll also need something like TMPGEnc to mux the elementary stream produced into a program stream that can be used by DVDA.

My project is a slide show of mostly black and white pictures. The transitions are mostly fades, but there are a few panning and zooming shots thrown in here and there. I must have tried to render this thing a dozen times. No success.

Try using a high constant bitrate of 8000.

I was getting a similar problem (in studio 8...ugh, glad I left that) but
using higher bitrates diminished the problem.

Then I moved to Vegas and use it's constant bitrates. No problems.
