OK, it looks like this is directly related to having Motion Blur turned on per-comp in AE.
I just shut of all Motion Blur for the comps over in AE, and now playback seems normal. And now that I think about it, the problem spots occurred with comps that had Motion Blur.
The next question is whether there's a way to get that Motion Blur back into my final renders via dynamic link...or will I have to go to AE and render out my comps from there?
OK gang, that didn't solve all my problems like I thought. I still had an instance of the flashing going on.
So I disabled my disk cache in After Effects, and Purged everything. I get the sense that this might be related to cached frames...and there are just too many building up so the program (PrPro) gets confused?
If you're having a problem with a dynamically linked segment, it can be better to just render out an intermediate file and use that. Dynamic Link is good for a lot of things, but it can also break down in cases of complex, render-intensive items.
Quick question Alex , are your dynamically linked comps all in one AE project? Or have you created several AE projects that have a comp in each?
Just a couple of words to what Todd has already said.
Irrespective of the Dynamically Linked comps complexity, whether they are just simple colour correction or 3D scenes with a load of lights, PrPro always tries to play them on the fly and displays them yellow in the timeline until you render them by choosing 'Render Entire Work Area'. So your guess 'too many building up' may sounds correct.
Rendering too complex dynamically linked AE comps within PrPro may take ages (literally up to several days in some cases), whereas rendering them to lossless intermediate out of AE takes tenfold less.
So, you have two options to experiment and optimise your workflow:
1. Do not rely on PrPro ability of playing dynamically linked comps on the fly and Render Entire Work Area.
2. Render intermediate out of AE if rendering within PrPro takes more than several minutes.
Hope, it helps.
Since my comps are basically just glorified PowerPoint slides (CEO Update Message, anyone?), there's nothing complex going on. The interesting (and frustrating thing) is that PrPro was playing my dynamic links very very smoothly all week long. But then at some point yesterday, things just got funky.
What's more problematic, is that it's hard to determine where the problem would arise. I thought I had narrowed down the problem comps, and I replaced those with renders from AE, but lo and behold, when I exported from PrPro, the stuttering showed up in other spots throughout the video.
There are 30 comps in all, ranging from about 5 seconds in length to a max of 30 seconds in length.
Oh well. Dynamic Link was really handy for planning and doing the initial edit and working out timing...so I'm very pleased with that aspect.
I wonder if you are still able to get back to the point where playing the timeline was smooth as silk?
And second, what is your bit rate on exporting out of PrPro?
Some sections play well, but not everywhere, especially where there are some camera moves.
I'm just exporting a 1200kbps 640x360 wmv right now.
Well, in that case I'd turn my attention to something outside of the Suite at all...
Alex you never answered my questions and I might be able to help you if you do.. to repeat..
,are your dynamically linked comps all in one AE project? Or have you created several AE projects that have a comp in each?
Very sorry. All comps live in one single AE project.
Thanks Alex. Thats the right way to do it. Sorry, that eliminates my possible solution.
Do not overestimate your personal perception of 'the right way to do' - it doesn't match what things actually are.
Do not rush to post after Todd.
Dont be so quick to tell others what to do....dont insult others intelligence...dont be so adversarial...
> Do not rush to post after Todd.
That's an odd thing to tell someone.
I think that Tom has at least as much to offer on this subject as I do. I may have access to the code, but I'd bet that Tom has more hours of actually using it.
