Hi guys, did a bit of 240FPS filming and want to slow it down to play at 24FPs, so that it plays at 10% speed, for some smooth slowmo. The problem is, when I simply reduce the speed manually, I think it's cutting out frames and not utilising the 240FPS?

I've done a bit of googling and it appears I need to "conform" the footage. Anyone know how I can do this? Is iMovie going to be able to do it, or is that too basic? I have Final Cut Pro 7 aswell, but unfortunately don't have the cinema tools plugin!

Any other ideas? Spent about an hour playing around last night, but it's much more in depth and complicated than it would appear to just slow something down!

I'm sure you can do it using Cineform...just select the bit you want to be slow mo and export it at 24fps?

Here's something lifted from another forum...

The way I have been doing slow motion starting with 240fps is working out very well so far.
I begin by importing the 240fps clip/s into Cineform Studio and set the IN/OUT points first then in Advanced Settings I set the Frame Size to Source and the Frame Rate to 10fps for the slowest I can get without stuttering.Set Format to AVI and Quality to High.
Send that to the conversion list and convert.
In Step 2 make any adjustments to White Balance and Exposure,Contrast etc if I so desire.You can use key frames to zoom & pan there too but I find it quicker, easier and smoother to do this in Movie Studio(Vegas).
Then I export MP4.

good stuff glad I could help.

That cineform software is actually really good for a lot of stuff.

I'm pretty new to video editing and was importing the big raw files from the gopro into Final Cut Pro X.

Once in I was then cutting it all up to the clips I needed.

Now I just use cineform and set the in and out points and only convert whats needed.

Much easier
