outputting pre-interlaced video
So we’re just getting started in FCP – we’ve used a lot of PC type video editing programs such as premiere and we’ve made the big leap to FCP. We’ve captured 10mbps uncompressed video off of our digibeta and imported it into FCP. It appears that the video source is already interlaced, but it seems that when compressing the video via compressor for use in DVDStudio Pro, the video is turning out double interlaced which, of course, makes the video look just awful. The easiest way to fix this (as we really dont want to run a deinterlacer on the video itself) is to turn off the field dominance on compression. We’ve tried to find the controls for this, but we have been unable to locate it. We have found the location where it allows us to switch from top, bottom, progressive or auto but no simple off. Can someone help?

Digibeta is interlaced, lower field dominant, and unless you somehow changed that setting by accident, you should not have to concern yourself with interlacing or deinterlacing. Are you looking at the video on your computer monitor rather a broadcast monitor? If so, then you will certainly see interlacing, especially upon movement. Ignore that, it will not be evident on a TV or broadcast monitor.

Actually – it’s on TV after being output to a DVD.
The video is visibly interlaced on the monitor — and appears to be “interlaced again” when output to a DVD and played. The result is that the video looks very shakey.
I ran a de-interlace filter on the video which fixed the problem… but instead the video looked more sluggish and not as smooth.
btw: thanks to anyone that can provide insight

In that case, somehow your field dominance has been switched. As I recall, some of the VBR encoding presets are buggy. Try changing to CBR encoding and see if that fixes things. If not, swap field order dominance of your video and try that.

Thanks! I’ve tried all the different field orders — but I’ll try CBR and see if that makes a difference.

Hmmm – didn’t work 🙁

Very very strange.

NTSC maybe, but PAL digibeta is upper.

Must be part of that stiff upper lip thing Peter.

No, just an annoyance that people think the whole world revolves round NTSC

Peter,
Of course the world revolves around NTSC, thats because the USA is at the center of the universe…
