Just a few questions about Correct Frame Rate Conversions in Post, Monitor Playback & 3:2 Pull-Down during post that I hope some of you can help answer.
CORRECT FRAME RATE CONVERSION
- When working with footage with different frame rates (24, 23.976, 30fps etc), what's the best timeline settings? If I have the most 24fps footage, should I set my timeline to 24fps and import the other footage into that timeline?
- What happens to the 23.98fps footage when imported to a 29.97fps/29.976fps timeline? Does, e.g. Premiere Pro/Davinci Resolve make an automatic 3:2 pull-down?
- What happens to the 25fps footage when imported to a 23.98fps timeline?
- When does optical flow, frame blending and motion interpolation come into play when conforming from one fps to another fps?
- I know that in most NLE's you can "interpret" the footage and change the native frame rate to something else but when would I want to do that? Maybe some examples would help me understand a bit better.
- When does reverse 3:2 pull-down come into play in post-prouduction?
- What's the difference between 29.97 and 29.976, and when are they used?
- What's the difference between 23.976 and 23.98?
- When you have 24fps footage that you intend to show on television in NTSC (60Hz), do I need to make a 3:2 pull-down? Which then makes it into a i60 footage (which is interlaced for broadcast), correct?
- When playing back 24fps/25fps/23.98/23.976 fps footage on an external grading monitor, should I set my monitor to 50Hz to avoid judder? And for footage with a higher fps, should I set it to 60Hz?
