  • 59.97 to 23.98?

    Posted by Christoph Green on May 26, 2011 at 2:53 pm

    I’m outputting a show that was shot with a combination of 59.97 and 23.98 footage. We edited all of the footage in a 59.97 timeline which worked very well. We had no problem with the SD or Bluray output but on the digital deliverables we are getting kickback from QC.

    this is their feedback:“File presented as ProRes HQ 1280×720 at frame rate of 59.97, however, frame rate is achieved by duplicating fully progressive frames at cadence of 2:3:2:3 (two repeated frames followed by three repeated frames) suggesting the original source was 23.97 fps.”

    Should I reload my Varicam tapes (the 59.97) as 23.97?

    DVCpro framerate converter just slowed the footage down.

    Any help would be greatly appreciated.

    Thanks!

    [Dave LaRonde] “The good news is that the 3-2-3-2 cadence being reported is precisely the way a film frame rate should be spread across a video frame rate.”

    yeah I don’t get why that would be a problem.

    give them a cookie for guessing correctly.

    Thanks for the quick reply.
    Yeah, the QC folks are not happy with the explanation. Looks like I’m going to have to jump through those hoops.

    Is there a reason I shouldn’t use Advanced Format Conversion in Compressor to convert the 59.94 to 23.976? It looks like it’s working…

    Thanks!

    Did they tell you NOT to shoot 23.98? Did they want all the master footage to be shot 59.94? That seems to be what they are indicating. They said “this looks like it was shot 23.98…” Well…yeah. So? The frames are repeated properly…so what’s the problem? The problem is that they seem to have NOT wanted the footage to be shot 23.98.

    I’d ask them about that.

    What they claim is the problem is that the film has mixed frame rates at the source so that the 24p footage needs to put in frames to conform to the 59. They don’t care what the frame rate is as long as everything is native.

    It wasn’t a problem with the DVD or Bluray QC just the digital delivery (iTunes).

    Completely agree with Shane. I have no idea why they would kick back something shot 24p, mastered at 59.94 (not 59.97).

    Do they not show any films?

    Reloading Varicam footage will produce the same cadence.

    Advanced format conversion isn’t going to do what you either, not with any quality anyway. Think about what you are trying to do, make 2.5x more frames from your current frames. That’s a recipe for disaster.

    I’d get on the horn and ask what the problem is. Progressive 3:2 pulldown is totally and completely normal. Asked them if they have ever watched Mad Men, or any big TV show broadcast in 720p that was shot at 24p.

    Are they pissed because the cadence changes?

    [christoph green] “at the 24p footage needs to put in frames to conform to the 59. “

    That makes zero sense. They want the 23.98 footage to NOT repeat frames? but to be single frame by frame…some sort of frame blending? I don’t get what they want.

    I’m taking out the frames (converting the 59 to 24) will that still have quality issues? (They are perfectly happy with 24.)

    That’s going to be worse.

    I don’t understand their argument.

    This sounds completely nuts. What network is this? Can you call someone higher up? From all description you are doing everything right and what you will end up giving them will be inferior.

    By the way… I just edited a prime time special that aired on CBS this week…. being pro-active, we called the network about some marginal video we wanted to include in the show. We offered to send him a tape to make a judgement about whether it was air-worthy, as taking it out at the last minute, if it failed QC would have been a costly disaster. The guy at CBS said…

    “This is an unnecessary exercise… do YOU think its okay for broadcast?” We said “sure”. He said “That’s good enough for me.”

    This was CBS. Prime time.
