    How to output as DVCPRO1080i60 at 23.97

    D M Vance



      I have an AE file that needs to be output to FCP, and the settings provided to me by the editor are the standard DVCPRO1080i60 but at 23.976.  This wasn't a problem until I tried to output the project and found that AE forces a 29.976 frame rate onto the outputted movie.


      I understand that CS5 has become stricter with these settings viv a vis Quicktime, but is there any way I can output the movie in 23.976?


      Thanks for any help you can give.

          No such thing as DVCPro 1080I60 at 23.976 fps... DVCPro HD is a codec. One of the acceptable frame sizes is 1280 X 1080. If it's 1080 can't be anything else. The frame rates for the codec are a little more complicated. Here's a clip from the specs from Final Cut concerning DVCPro format:

          Frame Rate


          DVCPRO HD supports both NTSC and PAL frame rates:

          • NTSC: 59.94 and 29.97 fps
          • PAL: 50 and 25 fps
          Note: The Panasonic Varicam camcorder has an option for true 60 fps recording (versus 59.94 fps), although Final Cut Pro does not support these rates when capturing via FireWire.The 1080i60 format can record 24 fps progressive footage with standard pull-down (2:3:2:3) or advanced pull-down (2:3:3:2).Camcorders capable of recording 720p60 footage can also record 720p30 and 720p24 footage. Camcorders that support 720p50 can also record 720p25 footage. Tape-based camcorders achieve these frame rates by duplicating frames and flagging them for removal during capture (or with a frame rate converter). P2 camcorders such as the Panasonic AG-HVX200 can record natively (without duplicate frames) to the 720pN30 and 720pN24 formats. The Panasonic AG-HVX200E camcorder supports 720pN25.Some DVCPRO HD camcorders support variable frame rate recording in the 720p format. In this case, the video is actually recorded at 60 or 50 fps and duplicate frames are flagged for removal during post-production. Duplicate frames can be removed using a frame rate converter.

          Scanning MethodDVCPRO HD can record either interlaced or progressive scan images, depending on the frame size and format.

          • 1080 lines: Interlaced or progressive (via advanced pull-down)
          • 720 lines: Progressive only

          I'd take some raw footage from your editor and look at it's properties. I'd guess that it's 60i with 3:2 pulldown which must be removed to turn it into 23.976 (23.97) progressive. I don't think your editor completely understands the format.


          If it were my project I'd work in a 23.976 fps full hd comp and render to something like Pro Rez 422 and use that in the edit. You'd then edit in 24P and I wouldn't render to a DVCPro codec for delivery unless that was absolutely required by the client. DVCPro HD is an acquisition codec, not a delivery codec.
