Rendering with MainConcept AVC format

I was having serious difficulty rendering a project back into .MOV format so after some research I read that Main Concept AVC format is probably the best setting to use when rendering with Vegas (although some of you may disagree).

Anyhow, I rendered my project using MainConcept and it rendered fine into an mp4 file. However, when I watch the playback on Quicktime, I noticed that there is like a line flickering when there is a lot of movement in the picture. For example, if a subject is sitting still in a chair, the footage is fine, but when they stand up or make a large movement, a line flicker appears across the screen where the movement is. I am assuming that I am doing something wrong somewhere in the render settings. The footage was shot on a Panasonic GH1 in .MOV format (1280x720) at 30fps. Playback on the timeline in Vegas itself is fine but when it's when I render it out onto my hard drive and watch the playback, that when I see this flickering effect during movement in the picture.

Just to clarify, my plan is to render this footage out and then re-import it back into a new project in Vegas so I can cut and edit clips from it to make a trailer for the main project.

Am I using the wrong render settings for this purpose? Can anyone help me out here?
 
Have you tried watching in VLC mediaplayer, I think Quicktime can sometimes do funny things.
 
Hi wjauch,
Just downloaded VLC media player and the playback of the project on it was perfect. Thanks so much for that. Now, I.m hoping the quality of this rendered file will not be affected when I re-import it back into Vegas for the purpose of cutting and editing it into a trailer? In other words, can a file lose quality if it is rendered over and over again (rendered out, imported back into Vegas and rendered out again)?
 
A file will lose quality with each re-rendering to a compressed format such as MP4, for a trailer destined for youtube I think you'll be fine. For your real project I'd suggest sticking to lossless format, I believe AVI is one, the price is much larger file sizes.
