Interlacing In 24p Project
I imported footage from Digibeta into an Avid Symphony Nitris, Avid Version 1.0, at OMF 1:1 and I’m getting interlacing. The footage looks fine when playing and the interlacing isn’t bad, but I thought progressive means no interlacing at all. I haven’t converted the files in anyway and I haven’t applied any effects, so I’m not really sure what’s going on. Did I have the wrong expectations?
I’m not deep into the project so it’s keeping me from moving forward but I don’t want this to become a problem when I get to the final cut.

When you say, “imported”. do you mean capture? Or do you really mean imported?
If captured – what were the original sources shot on? Film transfer, HD down convert, etc.” If so, make sure the timecode to pulldown cadence relationship is correctly set for the material being cpatured.
More details will help refine an snswer.

Thanks for the quick reply. It’s a Super 16mm transfer to Digibeta captured at OMF 1:1. Sorry about the sparse information, let me know if you need to know the deck model or any other info.
I didn’t know you can set the pulldown cadence in Avid like you can in FCPs Cinema Tools. I thought it was odd that I didn’t see a function for it though.

Usually for film to tape transfers, you should have received a transfer log as either ALE, FLEx, etc. that you import then batch capture. In most cases, the transfers are done with “A” frame falling on timecodes ending on 0 and 5 such as 00, 05, 10, 15, 20, and 25. If you log on those, you should be fine. Pullin is an essential part of the capture process and has been in the product since 1992…
You can also set the 00:00:00:00 to “A” frame in the Film/24 settings to automate this during capture on the fly.

I changed the Edit Play Rate from 23.976 to 24p, the cadence to Standard 2:32:3 pulldown, and the phase of timecode to A; this last one I might have to change once I bring the tapes in. Thanks a lot for the help. I’ll report back once I recapture the footage.

Let us know. If you are in a 23.976 project, I would recommend leaving the edit playback rate at 23.976.

I’d rather switch it to 24fps. What kind of problems will I encounter later on? If I just have to adjust a few frames in my sequences here and there I’m not worried; I haven’t even synced a 20th of my footage yet. But, if it might effect the video and audio locaters and mark-in points at my slates, then I’ll be worried.

PS – I really have to thank you for the prompt and informative replies.

What project type are you in? That setting doesn’t affect anything as far as timing of frames, locators, timecode, EDL’s, or lists of any kind. It only sets the playback rate of the timeline to be 24fps. If in a 23.976 project, the audio sample rate will now be 48.048kHz if dumping to a digibeta deck or other digital deck, the clocks will not match potentially causing artifacts in the high frequencies.
