HD to SD

Evidently not. For me, Compressor by default sets it to Upper. I’m guessing that may be why. I’ll keep you informed when the conversion completes.
Thanks

I still see some horizontal lines – is this normal for the conversion. I set the fields to Lower and it seems I’m getting the same results.

Not sure what to tell you. As long as you have not altered the HDV 1080i timeline in any way or altered the Quicktime you sent to Compressor, you should get a good SD conversion. We do this all the time here from 1080i sources.

Ok, for all I know something may have been altered. As you said, its can and has been done before. I’ll just have to do a clean recording and edit and see what happens next time.

[walter biscardi] “NTSC Standard Def is lower field first.”
not always. Digibeta and BetaSP both NTSC Standard Def and are upper field first.
HDV is upper field, so compressor needs it to be set for upper field otherwise out of order field jitter occurs.
Every pro deck I’ve come across is upper field, where consumer gear and cameras are typically lower field.

Ok, maybe that was why Compressor had that field as a default, not sure. what i do know is that I could tell it was definitely interlaced viewing it on my monitor, haven’t tried it on a TV yet. My timeline may have been altered, as Walter mentioned. I just know that the quality I saw was not even at the caliber of Standard Definition.
More tweaking I guess.

Ryan,
There are now seventeen posts in this thread, mine makes number eighteen, and in the whole time you’ve spent discussing interlace issues you never looked at your stuff on a TV or a real video monitor?
Computer monitors are not capable of displaying interlaced material properly without revealing the interlace. The better the monitor, the more your will see the interlace.

compressor in the presets I think defaults to “automatic” for field order interpretation. This is normally ok for compressing exports from final cut as self contained movies or directly from the timeline.
there is a bug in compressor though, where CAPTURED footage going straight to DVD will actually have incorrect field order jitter.
I have a special mpeg 2 dvd preset just for beta sp or digibeta captured only footage which forces upper field first or else I have problems.

What? In FCP/Apple quicktime codecs, 601 NTSC is lower.

Yep, here in California too… I guess maybe the standards, like the people, are a little different up in the Pacific Northwest where Chris lives.
