Forums Adobe Premiere Pro NTSC Interlaced to 60p in Premiere

  • NTSC Interlaced to 60p in Premiere

    I am experimenting with converting NTSC interlaced to 60p, rather than “deinterlacing.” To my surprise, dropping an NTSC clip into a 60p timeline in Premiere appears to do a Bob and Weave “deinterlace” converting fields to frames 1 for 1.

    Can anyone confirm this? I’m working with degraded archival and it’s tough to confirm with 100% confidence.

    Premiere may be reversing field dominance in my test, but that should be easily fixed by changing the clip settings.

    Cheers,

    I assume you mean 29.97 interlaced? me and a friend did a bunch of quality control tests by comparing against after effects. if you make an image sequence with effect large counting number in a AE comp 60fps timeline, then render fields out, then each frame becomes a field.

    and you can step through fields. I would then import into premiere. but if you are doing 59.94 fields instead of 60 fields/sec, you’re gonna have a duplicate frame in there somewhere because its not 1:1. premiere does a lot of whole frames converting when you have certain supporting sequence like 23.976/ 29.97 pulldown, and double fields/frames.

    Having to press the arrow keys twice to advance frames is a sign that
    you’re working at i30. Also, make sure the Sequence Settings dialog box is progressive and not interlaced. but you’ll want to set your footage as interlaced.
