Annoying Green Line

I am not so confident we will get help on this issue, Compressor it's not a very active forum.

I have the same problem when creating a small video for the web. My large videos are fine.

I had the same problem; solved after a lengthy overseas phone call to TEXAS USA, to a top editor in Apple... Make sure the WIDTH of your film export is in a multiple of 16.

Read more about why a multiple of 16 works well here: http://discussions.apple.com/thread.jspa?threadID=1802274

Short answer. With MPEG-2 and MPEG-4 (and other DCT based codecs), compression is applied to a grid of 16x16 pixel macroblocks. With MPEG-4 Part 10 (AVC/H.264), multiple of 4 and 8 also works, but 16 is most efficient.

Same issue here
Compressor 3.0.5 on os x 10.6.6
Green horizontal line and bad quality video file (unusable) as soon as I have Frame Control on. No matter what settings.
I have another computer with 10.6.4 and there's no issue there.
I tried to reinstall compressor and q master (using the utility to clean delete the files) No luck.
I make mpeg 2 files for a PAL TV station so I can't alter the size of the anamorphic video (PAL 720*576)
Looked everywhere on the net... no luck.

Until Apple PROGRAMMERS FIND A SOLUTION! !!
here is a workaround for the corruption (half screen green) when using compressor to downscale and de-interlace
In my case the use of the "Frame Controls" Tab when compressing to mpeg2 PAL Anamorphic from HDV leads to a corrupt Mpeg file with half of the screen covered with a green band every time.

But when I compress a scaled down file, turning "Frame Controls"off, then the problem disappears.

I must add an additional compression process: I re-import my HDV master into a Final Cut Pro timeline with the following settings
Frame size 720x576 Aspect ratio CCIR 601 / DV PAL (5:4)
Pixel Aspect Ratio: PAL - CCIR 601 (720x576) Anamorphic 16:9 Clicked
Field dominance None
Edit Time BAse . 25
Compressor Appel Intermediate Codec
Quality 100%

!! Make sure NOT to change the settings to match the clip when importing your HDV file!!

I then import my HDV master into the timeline and applies the de-interlace filter.
I then export this timeline to a new Apple Intermediate Movie ("re-compress All frames" option clicked)

I can now use Compressor to export my MPEG movie.
The quality is actually higher than using compressor's "Frame Controls" : I looks like FCP resizing filters are superiors (much less aliasing in the resulting file).

With my 12 core 2.93MHz Mac Pro the entire process for a 13 minutes movie takes:
6 min for the timeline export process and 45 secs inside compressor exporting to mpeg (using Qmaster in 24 Cores Mode) thats 6:45 processing time total

I guess you need to add a little of time for the extra step involved, but at least it works and the output file is great.
I also tried using ProRes in the timeline format: it works great but takes 2 mores minutes for a 13min file and the end result is only very slightly superior or maybe not even superior.
