  • 59.94FPS to 23.98 Question

    Posted by Dustin Parsons on December 29, 2007 at 1:34 am

    I’ve moved a few 59.94FPS clips into a 23.98 sequence and most of them look fine. One of the clips, however, looks very jittery/flickery, almost like slow motion. I uploaded the clip to my website so you can get a better idea of what I’m talking about. The first shot is 23.98, the next is the jittery 59.94, and the next shot is another 59.94 that looks fine.

    This is the only clip that I’ve had problems with. Any help or suggestions is greatly appreciated. Thanks.

    First of all, I must admit to NOT being an expert whatsoever. Having said that, here are my thoughts/observations.

    I stepped through the jittery clip, frame by frame, and what I’m seeing is that every frame is repeated (i.e. 50% speed change with no frame blending). You might want to try to open a copy of that particular clip in Cinema Tools and conform it to 23.98 to see what it looks like then.

    Good luck!

    This happened to me with the 1st Varicam project I did. 95% of my footage worked fine but some of the shots came in stuttering like this.

    I don’t remember how I fixed it, but I did. Try the DVCPro framerate converter tool. Or re-capture those shots as 23.98.

    Thanks for the reply. I just tried going through Cinema Tools and I was able to conform the 59.94 to 24 (I didn’t have an option for 23.97) but it did not drop any frames, resulting in slow motion.

    DVCPRO Frame Rate Converter seems to work for me because apparently the Panasonic HVX flagged frames for a 23.98 pulldown so instead of giving me slow motion it conformed the 59.94 footage to 23.98 without changing the speed.

    Thanks!
