Hello, everyone out there in Adobe land!
I've looked for posts with a problem similar to this one, and couldn't find one so I'm sorry if there's another thread out there addressing this. I've got some strange glitches coming out in my renders, and can't seem to figure out why.
In this case, the composition consists of one layer of largely chroma keyed footage laid over a static .jpg backdrop. I'm getting pixellation and strange artifacts apprearing in the footage, with accompanying audio glitches at the same spot. The audio and video do NOT appear to be out of sync on this particular clip.
Here are some screenshots:

Please let me know if there's any other information I can provide that will be of use.
Everything else in the video looks great, it's just this one bit where I'm getting these odd glitches.
This isn't a particularly huge project, I'm a bit surprised to see this stuff.
Thanks in advance!

I'll try giving that a shot, I'll do a test render with no filters as well to make sure that the original file isn't fragged at the same time.
It's F4V because we stream our videos over a flash media server, and F4V uses AAC audio (for some reason, our server seems to like this way better).
The videos are resized from 1920x1080 to 1440x1080 because that's what our web guys have demanded, why they can't post our videos as 1920x1080 is beyond me.
I think what Ann is saying (she will correct me if I am wrong) is that you match your sequence to your video for EDITING... and you then change the video size when creating your output
At least, that is what I do when editing HiDef 1920x1080 AVCHD in a matching sequence, and then I output to 720x480 AVI (widescreen PAR) to create a DVD
Edit in native format... export to anything you want

Yessir, I've been doing this, except I'm exporting to 1440x1080. I am indeed editing in native format.
The problem I'm running into now is my footage looking horrid when I render out to a lower bitrate. It's looking good at 1500 KBps, 1250 KBps and even 1000 KBps, but when I get down to 500 KBps or 250, especially 250, it's all coming out as pixel vomit, as well as motion being glitchy and stop/go. I've tried activating the anti-flicker filter on my clips in project, no dice.
Here are some examples.

Got it sorted.

Steven Blair did you de-interlace? double check it.

Dan Voluntarist Lyons I will! Thanks!
Steven Blair I never read through your whole post there. Deinterlace normally only needs to be done when you are importing mpg 1,2,4 or AVI, but I say click it anyways. It causes all kinds of problems here with people bringing me footage they say is not working. That almost always fixes it.
Steven Blair I only see stills but if the static areas look find and the people make crazy weird water like effect when there is movement... that's a deinterlace.
Steven Blair yeah it does bro, right click on the video (in the timeline). Click on "field options" and then click the radio button that says "de-interlace"
Dan Voluntarist Lyons Holy
, you are Godlike. THANK YOU!! How did I not know that?
Steven Blair I can't believe you've been editing this long without deinterlacing your clips haha, I deinterlace EVERYTHING.
Dan Voluntarist Lyons I don't know. I'm about to go flog myself as penance.
Dan Voluntarist Lyons I'll let you know the moment the render finishes! Dude. Seriously. I think this just completely changed my game.
Steven Blair you can also do a ghetto deinterlace but bumping it up to 50fps and clicking the de3interlace option in the encoder. You effectively slice your video into ... a
load of bitmaps. Then it squishes them all back together making a video that plays like an old school cartoon.
Dan Voluntarist Lyons Huh, interesting. I'll give it a shot.
Steven Blair Heh, I'm actually getting good at this.
Welp, the issue is cropping up again. I THOUGHT I had it solved, but arrrrrr, curses! It has reared its ugly head again, and this time the deinterlacing has no effect. It's like fighting the borg, it adapts to my solutions and keeps coming back.
It doesn't look so bad after being uploaded to youtube: http://www.youtube.com/watch?v=dOmReq878DU
However, when watching it in Adobe Media player locally on my computer, it looks... Suboptimal. I still see a glitchy, blocky mess much like this:

I'm also wondering if this has anything to do with my computer's video codecs, as it doesn't look that bad on youtube.
