Pixelating after render
I have ran into a problem that I have never had yet and it kinda has me baffled. A client brought me some MiniDV tapes to edit and dump to DVD. I rendered each tape as a seperate project and one of them has a pretty noticable pixelating problem for 10-15 seconds in the middle of the project (these were standard 1 hr tapes). At first I thought I probably just had a bad disk so I burned another one…same problem in the same spot. So I zoomed in on the AVI file on the timeline where the problem is and stepped through it frame by frame and saw no apparent problem with the AVI file. I rendered these files to MPEG2 at variable bit rate (8000, 6000, 2000) with render quality set to best (audio seperate ac3). I ended up deleting the MPEG2 file and re-rendering it two more times, the last time using 2 pass render. Got the same pixelating problem in the same spot each time. When I showed it to the client he said that it wasn’t bad enough to really matter to him and was pleased with the finished products, but I’m pretty picky with the quality of the work I let go out of my studio. And I can’t for the life of me figure out why this is happening when the original AVI shows no problem in the spot at all. Any ideas what might cause this? This only happened on one out of four tapes of the project. I just defragged shortly before I started this project.

Just curious. How did you capture them? Any done differently? Were the tapes the same brand? Age?

Captured via firewire from a small digital camcorder. I do not play anyone else’s tapes in my VX2100 so I used their camera to capture from. All four tapes were recorded the same day but on different recorders. The tapes were shot from cameras mounted inside an airplane cockpit. It’s just strange to me that the problem does not show up at all on the timeline…only after rendered.
