Interlacing issues compressing mpeg2s
This may be a problem that has a basic solution, but I just haven’t been able to figure it out.
I am trying to encode several m2vs in compressor from master Uncompressed 8-bit quicktimes. They all came from digibeta sources; and most of them look like they were originally shot on film.
I’m getting major interlacing problems when previewing. I don’t want to use a deinterlace filter, and don’t know why I should have to. It’s every single masterfile from a digibeta source that does this. so i feel like it’s a misinterpretation on FCP or Compressor. I’m hoping it some bonehead simple adjustment on my part.
Ideas?

Are you looking at it on a computer monitor? If so, you’ll see interlacing. View it on a real video monitor.

Ben,
If they were shot on film you are likely seeing pulldown. In After Effects you can remove the pulldown and change the frame rate back to 24. I used to do this all the time at an agency I worked at which always shot film, and we did this to put the spots in Powerpoint, always worked great. Not sure if you can do this in Motion, but it’s worth a shot if you don’t have AE. Combustion will do this too, I believe.
Have a wonderful day.

Yes, I’m looking at it on a computer monitor, so you might be right. I’m working from home, so my only option is to burn each m2v to disc and look at it on a television. Sometimes they come out right, sometimes they look just as interlacey. Any real reason for this?

As Chris said, maybe it’s the pulldown if it’s from film. Maybe look into whether the fields are reversed too.
