  • Footage from DVX shot 24pa, appears to still be interlaced when edited.

    I shot all of my footage 24pa, and I’m editing it in premiere pro 1.5 in a standard Panasonic timeline. From what I understood about 24pa from the DVX book, when put in a 24p timeline, premiere would discard all interlaced frames, leaving a true progressive image, but when I scrub thru my timeline while watching the footage on my external monitor, about every 4th frame is interlaced, and on the computer monitor, there are still interlace artifacts on straight lines. What is the problem!

    Premiere Pro detects the “cadence” to remove the extra frames. If by stopping and starting during the recording process this can throw off the “pattern” of original and inserted frames. Does all the captured footage exibit the same problem? Or is it just on certain parts? I would suggest re-capruring a small protion of the problem area (with no “cuts” in it) and see if the problem persists.

    Anyone else have any ideas?

    by “stopping and starting during the recording process” are you referring to batch capturing logged footage? I definitely did do that. I didn’t capture each tape as a one shot session, but logged by shot and take.

    Sorry for the vaugeness. I was thinking that you might have captured everything in one pass. After this responce I am thinking that there might be an issue with the batch capture process. I don’t normally do shoots that require it. Mostly single shots for an hour or so.

    Definitly try capturing a small sample of a problem area manually and see if it still gives you problems.

    So, premiere tries to recognize a “cadence” to remove the 3:2 pulldown? Does all other software with a 24p timeline do this? I have 9 tapes worth of footage already logged, captured, and edited, and i’m definitely NOT going to recapture it, but there’s something I just thought of. After effects, under the interpret footage dialogue, has an option to detect 24pa pulldown and remove it…I need to bring my edited footage into after effects anyway to color grade with color finesse, if I remove the 24pa pulldown with after effects, is this a sort of “forced removal” that does that the same that premiere would do. If I use after effects to remove the 3:2, am I still ok with getting progressive footage without recapturing. Also, what do i need to render out of after effects to create a 16:9 anamorphic, 24 frame progressive DVD.
