Effects to Premiere Rendering clarification

Question

Guys. I did a premiere pro cs5 project import into AE CS5. THat project had a few avi clips with no effects on them. Now, I applied one simple effect in after effects, to reduce the video noise. Then I rendered the clip by saving it as an avi clip. I then imported that "denoised" clip back into Premiere, and it's messed up. There are black Boxes flickering every few seconds halfway across the screen when I try to play it back in Premiere. Also the render bar in Premiere is now yellow for that denoised clip? Also when I play the avi clip in a media player or vlc pplayer, it plays fine.
What is the best way for me to import a few video clips into After Effects from Premiere, apply an effect or to in AE, then export it back to premiere for further project work? It's just that If I do all my effects in Premiere first, then import whole completed project into AFter Effects, none of my Premiere PLugins work in After Effects. Isn't the whole point of these programs to smoothly transition projects between themselves? I also have encore and usually i would export just to encore. But this messes up my flow of things. What are some of your methodologies for creating a project that has plugins applied from both premeire and AE as well as the final output going to Encore? Thanks

Confusion, confusion! You need to get a few things straight first.
AVI just like MOV is a container format and can contain anything from legacy Windows CoDecs to AVCHD.
You cannot render to some of these formats from AE, since internally they use specific video processing that AE can't provide.
There are no "simple effects" - going AE always results in the footage being fully decoded, transformed to uncompressed RGB color and then the effect is applied.
Re-encoding afterwards happens based on the full RGB data, not the original source.
Hence, all of what you see is probably normal, with the exception of the random black blips. If your Premiere project is set to AVCHD, since there is no way to redner it directly from AE, you will always end up with an intermediary file in anotehr CoDec that requires a second conform in Premiere. It may play realtime, regardless, but then again it may not. Therefore the line is yellow, not green to inform you. The evil blips of black you see are probably due to unsuitable compression settings when outputing from AE. This in turn may lead Premiere to mess up. On the other hand, they could already appear in AE, but you never so them because you didn't run RAM previews or your footage interpretation was wrong, so fields were suppressed. Impossible to tell from your little info.
Isn't the whole point of these programs to smoothly transition projects between themselves?
It is not. Compositing and editing are different workflows. Some of what I said above applies here - different processing pipelines for different priorities and workflows. That doesn't preclude going back and forth, but it's not really the point. Your problem is that you seem to have no masterplan (no offense) and need to adapt your workflow. you need to decide on what to do where and when. Based on your comments, you are doing too much, going too far ahead in Premiere and going to AE too late in the process, so any project conversion can only be a lossy process. There are basically only 2 "good" workflows for removing your noise:
a) Apply all corrective effects before even beginning to edit, import corrected clips as fianls in Premiere. Downsides:
You may process footage that you never will use later
Duplicate footage = lots of drivespace required
You lose native acceleration in Premiere
b) Do a proper rough cut - edit the clips, but without transitions and effects, only defining the timing. Allow overlap for adding fades and effects later, open the sequence in AE, do effects, transfer rendered files back to Prmiere, replacing the original unprocessed soursce. finish the whoile piece. Downsides:
Last minute changes will require jumping back to AE
You may miss footage pieces
Overall composition hard to judge without transitions and audio in AE
So take a pick which to you is the two of the lesser evils. how you get your files across is anotehr matter, but since you didn't provide any details about your current process, I'll settle for a generic "anything from Dynamic Link to Quicktiem fiels wizth lossless compression (Animation, PNG). Feel free to post your follow-up questions on that one.
