stop frame ghosting

[Filip Vandueren]

The ghosting is probably FCP using Frame Blending when you time-stretch the layer, you can disable it, check the FCP manual.

In After Effects, you can import the pict-sequence, then ‘interpret footage’ and tell after effects to treat it as a 6.25 FPS sequence, now when you render to a quicktime@25fps the frame doubling will be done for you, but that’s probably just redundant info wasting disk-space. You can make a 6.25 comp and render to a 6.25 fps quicktime and FCP should handle that correctly.

there are a few ways to do this, here are the 2 easiest that i can think of…

using interpret footage settings:

select you image sequence in the project window then choose file>interpret footage>main. set the ‘conform to frame rate’ to 25/4 (that’s just he working frame rate divided by the number of frames that you want each frame to last).

now drag that image sequence into a new comp with a 25fps frame rate (if you already have it in a 25fps comp, you can use that, but you’ll need to lengthen the duration). step through the comp (page-down) each frame should now last 4 frames.

using time stretch:

select the image sequence that is in your 25fps comp. choose layer>time>time stretch and enter 400% and make sure that frame blending is not on for that layer. step through the comp and you should see each frame last for 4 frames.

thanks for the speedy response.it dosent have to be 4 fps. I was just trying that out.
how do I set an imported sequense to 5 fps?

i’d try what filip suggests… a 6.25 fps comp and see how fcp handles it… i don’t have enough fcp experience to know how it will handle frame rate, but it seems like it should work.

I think this is working and I found another problem.
my comp is 25 fps but the imported clips where imported at 30fps. how can set this up so it inports stuff at 25fps?

thanks for the info

[stewart charles] “my comp is 25 fps but the imported clips where imported at 30fps. how can set this up so it inports stuff at 25fps?”

in the preferences>import setting in ae. just set 30fps to 25.

if you new you were importing bunch of sequences that you wanted to all be a different frame rate, you could also use this setting prior to importing to create 5 fps sequences, for example…

but you can also use the interpret footage method conform one sequence, then apply that interpretation to all other sequences in your project using file>interpret footage>remember interpretation and file>interpret footage>apply interpretation.

thanks for all the info! I think its all sorted now!

Here’s how to set frames to be shown per time. It starts at 50% so just do it twice like the video says. It uses strobe and timewarp whole frames so there’s no blur or ghosting. Great tut that can be used for stop motion.

Hey Dave,

I think computers have no problem with 6.25 FPS, it might seem strange to us,
but I’ve had no problems with fractional framerates

thanks for the link Ill be checkign it out later today
