Full Render - When is this required	Can't Post

So when is Full Render required? It's my understanding that if you are sending something to compressor it doesn't have to be rendered anyway because all of that is done with the encode. Am I on the right train here?

Do you mean export using compressor? If so I don't know the answer to that as my work flow is different for exporting. I always "export to "quicktime movie" and select "recompress all frames" and "self contained movie". Recompressing all frames is like a final render due to my setting for the sequnce being at draft and fastest while editing. Be sure your setting are all correct for your sequence when doing a final render as well...

Okay, well my workflow has actually changed as of late too. I actually export the sequence to a Quick Time Move, and then I use that movie as my source file to encode the M2V and AC3 files using Episode. I've always insured I was exporting it from FCP as a self contained movie, but I don't believe I've been selecting "recompress all frames" I thought I was rendering the timeline by selecting Command R, but just recently realized that I didn't have "Full Render" selected from the sequence menu. So, If I understand you right, if I DON'T render everything from the timeline using "Full Render" Then I need to make sure I have selected "recompress all frames" when I export my movie, right?

I'm pretty sure that a full render will be done at the time you export your Quick Time movie. We use compressor in our studio, but sometimes output quicktime movies for other purposes, and I've never needed to do a full render prior to the export. It would make sense that you'd need to select "recompress all frames" but I don't remember if I've specified that in the past - I'll have to double-check the next time I need to.

Ron you only need to render if you want to see the results of a filter right then and there. I use several filters that take a honkin' long time to render, so I just put marks on these clips where I want to use these filters and I watch the clip all the way through by just imagining these filters in place. I know what they look like, I don't need them rendered.

So then at the end of the project I add the filters and send it over to compressor. The Compressor application does not access render files when outputting.

So in short, you don't have to render before sending to Compressor.

Okay, well that makes sense that compressor doesn't access the "render files" I remember Todd Gillespie talking about that in his Video 07 seminar. Stating that you only need to render if you want to see them because Compressor renders them anyway.

So, I suppose Episode does the same thing.

This is incorrect. How your movie exports is totally dependant on the sequence settings...

Sequnce settings/ video processing tab/ motion filtering should be set to best.

sequence settings/ render control tab
-frame rate 100%
-resolution 100%
codec - same as sequence for SD, or proress for HDV
master templates - best

These are the things I set to draft and fastest to enable the best performance while editing a sequence. When I'm done, I change them to the best settings for final output.

If I've rendered the sequence because I wanted to see it in it's completed state prior to export, then I do not need to check recompress all frames when I do actually export it.

Thanks Scott, I appreciate that explanation. Now I'm a little concerned that I didn't fully render some sequences before I exported them to a movie and encoded them to M2V However I don't see any noticeable difference in picture quality on the finished DVD's.

But you can be sure I'll make sure I've got a Blue line from now on before I export a final movie.

Just to make sure there is no misunderstanding... You don't need a blue line if you check recompress all frames...
