  • 24P Recorded on Nano as 30P-Fix?

    Posted by Bill Ruth on August 20, 2013 at 10:00 pm

    Problem: 59.97 with 2-3 24fps pulldown HDSDI output of camera recorded to Nano Flash with improper settings. Video was recorded as 30P because the pull down was not removed (checked). So the video has a number of frames each second that has “jagged, interlaced” looking edges.

    Is there editing software/hardware could correct this problem, something like re-interlacing to fields, “erasing” and “duplicating” fields so the jagged edges are eliminated and it looks progressive again?

    Is it 720p/59.94 or 1080p/29.97? A progressive frame with embedded blended “fields/frames” is harder to remove in 1080p/29.97. If 1080i/59.94, open in the files in a 1080i/59.94 first, then open than bin in a 1080p/23.976 project. Form there a motion adapter will be applied when you edit the clip on the timeline removing the 2:3 pulldown. If there is a hiccup you can open the clip in Effects mode and reset the ABCD cadence to correct.

    The recorded codec is XDCAM HD422 1080p30 (50 Mb/s CBR). Is there a solution to remove the blended “field/frames”?

    Something to try… open file(s) in a 108op/29.97 project. Then open bin in a 1080i/59.94. The frame rate mix and match should turn it into a 1080i. Transcode a test clip (with lots of motion) to 1080i/59.94. Then open that clip in a 1080p/23.976 project to see if it can do a better job with the 2:3 pulldown.

    That will work fine. The editor will be using Avid. I only edit on FCP7. So to test, I opened a clip in a 1080i59.94 timeline. Rendered an Effects/VideoFilter/De-interlace and copied into a 1080p23.97 timeline. Thanks!
