Hey guys i shot some 60fps videos... for later preojects i want to slow them down and render them into 30fps videos.

This is how i tried it:

1. import file in PPCC 2015

2. right click on video --> Modify --> Interpret footage --> and set it to 30fps   (video is 50% slower like i want it and its 30fps)

3. export  --> choose 30fps in render settings (picture)

But now the video looks very jittery... as if frames are missing or so ...

I also tried frame blend but it still looks jittery

please help me ... and tell me your work flow and how you are doing this

Correct answer Ann Bens

It is slowed down!

this is the original Video- clip

i take this original clip ....right click on it.....Modify....Interpret footage... set it to 29.97fps

and export it and choose 29.97fps in render settings

it slows it down by half but its really jittery ...


I downloaded the original but its shot too fast and quite shaky.

I think that is why you are seeing what you are seeing: jitter.

If you set the interpret footage to its normal framerate

Use the speed option and set that to 25% and Optical flow

you will have a much better picture.

Your sequence is at 29.97.  Your export is at 30.

Correct that.

I do see the issue.

This looks like the kind of judder I get when I move the camera too fast when shooting at 24 fps.  That even slowed down to 50% the motion goes pretty quick makes me thing it's the same here.

What shutter speed was used when you shot?


here is the same video but rendered as 60fps

click here

there is no jitter and laggs .... so something is wrong when i export it into 30fps

Just reduce speed on the clip in the timeline and set it to Optical Flow.

Export to 30p and dont use preview files.
