pulldown removal in Adobe CC

[John Heiser]

I have some spots that were shot/edited at 23.98 and send to me at 29.97 for slating and delivery though Adstream to networks. I've been happily doing that since February, and today got a QC notice from Adstream (for some re-tagged spots) that the pulldown cadence in the spots is 4:1. Stepping through the frames, I can see that. I was able to sweet talk Adstream in to accepting them.

Then, with time on my hands, I set about investigating. If Adstream had said, hey remove the pulldown and deliver 23.98p (which they accept), how could I do that? DS did it in one mouse click (sigh) but I'll be moving to Adobe CC soon and the process there is clunky.

ADDING pulldown is easy enough (23.98 into a 59.94 Premiere sequence results in 3:2; 23.98 into a 29.97 sequence results in 4:1). But I'm having trouble removing the 4:1. I haven't stumbled on the right combination of sequence settings and footage interpretation. 

And then there's AfterEffects.

So clunky. DS does this instantly. Any suggestions?

I don't think Premiere does or ever has provided any method of removing
or adding proper pulldown. You can mix framerates, but it's essentially
a timewarp from one rate to the other and I don't think consistent
cadence is guaranteed.. it's certainly not controllable.

In After Effects it'd be a matter of right-clicking your footage, doing
Interpret Footage, and selecting the correct sequence under Remove
Pulldown (one of the 24p Advanced methods at the bottom of the list.)

I suppose you could do that, then create a composition for each piece of
footage (you can do it in batch) and then link those comps into Premiere
for editing... but they won't quite be realtime.

We have searched high and low for a tool to remove the dreaded 4:1 "pulldown".  Does not seem to be one.

There is a trick where you varispeed your shot at 120% (if I remember correctly) with the most basic of vari speeds (frame dropping only for speed ups) and keep padding the beginning of the shot until the cadence of the varispeed frame dropping matches the cadence of your 4:1 pull down.  A bit cludgey but it does work.

I'll try that more deliberately today. Three good things: 1) these are finished spots, so there's not a "batch" requirement; 2) I'm still running my DS, so in this particular instance, I could have done it there; and 3) Adstream bought the 4:1 when I told them I didn't edit the spots, just slated and uploaded, so the problem went away.

To resolve 4:1 back to 24p you throw out every frozen frame. You'd have to link each spot in DS in a 23.98 sequence, split the spots into shots, cut out all the frozen frames, put the entire sequence into a container and add 3:2 pulldown. You'd then export the sequence to sequential files and link them this time from a 59.94i project. And that's that. Since your 4:1 phase is probably different in each shot there is no simple way to automate the removal of freeze frames. If  they were placed at regular intervals there are several things in DS that you could use to remove the freezes.

I believe what John is asking/what he has are spots that were done by
someone else originally at 23.98, but were rendered/exported out at
29.97 with 'advanced' style pulldown (whether it's interlaced or
repeated progressive) and he wants to turn them back into native 23.98.
Which, doing a 3:2 Advanced remove (which is really 2:3:3:2 rather that
regular 2:3) should do -- assuming the cadence is consistent. Which it
sounds like he's already done this in DS, and it is. But he really
wants to do it in Premiere, which can't (besides manually cutting out
every 5th frame.)

Our Alchemist XF does a great job of this.  You can even enter custom cadence pulldown to be removed.
