DGPulldown Frame Repeats

[sambat]

If I'm understand 25 > 29.97 pulldown, it's essentially creating six frames from five by repeating fields?

Assuming the existing frames/fields are:

1T 1B
2T 2B
3T 3B
4T 4B
5T 5B

Which fields (Top/Bottom)are being used from which frames to do this.

Yes, it repeats fields in a 3:2:3:2:2 pattern. I don't know exactly where in the sequence it starts. But assuming it's as I listed it:

1t 1b 1t 2b 2t 3b 3t 3b 4t 4b 5t 5b

Every now and then it has to make up for the difference between 60 fields per second and 59.94 fields per second. So it drops a field every 500 frames.

Thank you, that's the sequence I was trying for.

Sorry.
