Hi,

I have shot some 1080p footage overcranked to 50fps but want to use this footage at normal speed. I have often done this with the 720/50p and assumed the workflow would be the same but it isn't.

The problem I have ended up with is that if I drop some 1080p 50fps footage into a fcp 25 fps sequence and set the clip to be at 200% speed (so it would play normal speed) FCP does not set it to 200% precisely but at a little over 200% the amount over varies from clip to clip but its generally less than a percent over. This causes fcp to make a frame up and makes the clip look awful.

Has anyone used 1080p overcrank but edited at normal speed?

You can create a preset in Compressor. Pick an output format and your desired frame rate, then under the "frame controls" section, set "So source frames play at " ... it should show your specified frame rate. Then, all of the frames in your source file will be included in the destination file but play at exactly the new frame rate. (I hope that makes sense.)

Thanks - I will try that.

Is there no way to control how FCP reacts when a clip is dropped into the timeline? For example when you drop a clip in force FCP to use the clip frame by frame so a 50 fps clip in a 25 fps timeline would double in length or force fcp to keep the clip's length and drop alternate frames...

It is my understanding that Cinema Tools (a program that comes with Final Cut Studio) can "Conform" a clip to a different frame rate. Just open the clip with Cinema tools, click conform, select 25p, and then drop newly created/saved clip into your timeline. No rendering, just buttery smooth slow motion.
