NEED HELP ASAP FCP Time Mapping

[ansb]

Hey everyone!

So I have a problem. I am editing a music video that was shot on a Red camera. The video was shot using a bunch of different frame rates (24, 30, 60 and 90). I log and captured all the footage into FCP and am now attempting to edit through it.

In the browser it says all the video rates at at 23.98 (which makes sense as to what its being played back at). However during the shoot, they were playing back the music faster during the takes to match the frame rate. (Think something like Coldplay Yellow video) So now that I'm in the editing process I need to change the frame rates of the 60 fps, 90fps, etc. clips so that it looks like she's singing at a normal speed

I think this might be a simple fix and I'm just being stupid, but please help! Im on a time crunch and need to figure this out.

(i played with cinema tools, but it seems that just conforms it to 23.98, when they are already saying they're at 23.98 in the browser)

command j

60 is 250% slower than 24 for example.

ya see i tried that and the footage than plays back choppy and its way too fast

i think they screwed up the play back of the audio during the shoot

If I am not mistaken, music video playback is faster than real time.

ya. I was on set and they had her singing super fast to match the higher frame rate.....

so i would think i wouldn't have to change anything?? i don't think they screwed up the playback. I just think I'm not doing something right in FCP

right... so the frame rate of the camera speed (say 48 fps) needs to have a track that is speed up twice as fast as normal. Then when you bring in the footage, it's project frame rate of 24fps, looking slow mo, should play in sync with a normal speed track.

If they shot at 36 fps... you would need a track that is speed up by that factor x1.5, 96 fps you need a playback track that is sped up x2.5, etc...

If you only used one playback track on set, say a 2x speed track, only the stuff shot at 28 fps will be in sync.

right. i got that. so on set they did have a bunch of different tracks to match the frame rate of the camera (so when the camera was 60fps, the audio track played back 2.5 times as fast). so I figured once it was all brought in, it would should all sync up already. am i wrong?

nope... it should already be in sync. Was this shot on RED? Is the project frame rate of that camera, and therefore your proxies/transcodes not 23.98 fps?

 

[ansb]

ya i thought it should be synced already.

it was shot on RED. and the frame rate of the camera matches the project, because the clips that were shot at normal speed during the shoot at 23.98fps matches with the actual song in the project

how off are the over cranked shots from the track? Does it drift the further into the take you go or is it uniformly off?

 

[ansb]

it seems to be uniformly off. i synced the first words she sings with the music and then it seems to just seems to keep continously going faster than the music

 

[Brandon Kraemer]

here is what I would look at:

import the tracks they used at the different speeds on location... compare their durrations and get some math on that... how much faster are they actually from the real track?

Compare these results with the frame rates they were shooting at and see if the math jives. You will at least know if the tracks were sped up properly.

Since you can't verify the over cranked speed in the meta-data you are at the mercy of what they tell you it was shot at... but you can look at the shutter speed, which would give you a clue what the frame rate was, but that depends on other factors too. You need to deconstruct what was done on set, even in error to know how to solve the issue at hand.

Ask for camera logs and sound reports. All this should be documented. I don't suppose any one was slating with this info?

You realize you will not modify any picture tracks? You should have all the audio tracks they used.

Worst case, have the director tell you which tracks were shot at what frame rate.
