Thanks, Bob. I tried what you suggested, using Compressor. Every 4th frame is still duplicated. The original checks out at 23.98 and the conversion at 29.97. I’m looking at everything on a video monitor as well as the computer monitor; so I’m pretty sure I’m seeing both fields.

Bob,
The video house did a short test for me at 23.98P using AIC at 1920X1080. This is OK but when I drop it into an HDV 29.97 1080i sequence (as I’ll have to sooner or later in order to get a tape output), the motion is unacceptably jerky because FCP deals with the time-base difference by simply duplicating every 4th frame, even though the playback is set for 2:3:2:3 pulldown. I don’t see an obvious way around this. I may have to settle for a 29.97 transfer and fix the cuts that look bad one at a time.

Many thanks for your helpful suggestion.
I may have figured this one out. I had been bussing the firewire signal through my M-Audio box to the deck for years without any problem. But I disconnected the box and plugged the deck directly into the computer and got a clean output of the whole program.

Yes, a firewire 800 connection.

Thanks for the suggestion. My experience is that dual-layer DVDs sometimes produce a hesitation on playback when the player switches layers. Our project is a gallery installation involving 5 HD DVDs playing back in synchronization. Exact synchronization of the players currently on the market evidently isn’t possible; so we’ve had to settle for starting the machines together using an infrared relay. We find that holds to within a fraction of a second even after several hours of repeating. I don’t want to introduce more possibilities of synchronization or playback error than I have to.

Many thanks. Unfortunately at 25 Mbps I can’t fit 30 minutes onto the 4.7GB DVD. In cases where I’ve had a shorter tape, I’ve put the file onto the HD DVD in its native form, as you suggest, with very good results. But in a test, I wasn’t able to see any obvious difference between the native 25Mbps and the same material compressed further to 19Mbps.

4.5 won’t do HDV.

My experience is that (in NTSC anyway) there is nearly always skipping on the computer monitor and this doesn’t mean anything. The only valid test is playing the clip out from the computer to a video monitor (via video card).

Do you see the skipping on the computer monitor or the video monitor?

I meant capturing to a FW800 drive and playing back from it. Sorry for the confusing wording.
