Changing the FPS in a project

[MetroMikeNOVA]

I started a project in 60 fps, but then I realized that most movies and films run in 24 fps. This was a dumb mistake, but I was wondering if there is a way to change the fps from 60 to 24 in the middle of a project.

i know... goto export video options. override the framerate. then save and reload the session.

somebody else may have this element viewer trick. i never done it. dunno how this can break.

+ i'd recommend 23.97 or 30 fps tho. from my experience, straight 24 tend to stutter when playing back. it may be a software issue on my end tho. also using 30 fps avoids having to retime the shots. converting fps can introduces fractional timing redbaring the timeline and slighty messing up the sample timing on 'blade cropped' data transitions.

Can doing this corrupt the file?

the options thing can't corrupt it. the element viewer thing, if done wrong can break your file, yes.

in both cases, depending on the framerate, it may introduce the timing and sampling glitch. no way around that unfortunately.

I set it to 60 originally, that is a big jump so just to be safe, when I finish I will make two copies of the project. One being 60 and one being 24. Thanks for the info.

I personally work on sessions with them set to 60 frames per second, then export them at 30 frames per second, then close Source FilmMaker without saving the session and reboot it so the session file itself will remain set to 60 frames per second.
There's nothing stopping you from working in one framerate and just exporting at another (but of course it's not a bad idea to work in the same framerate as what you plan to export).

The arguably easiest and/or simplest and/or safest way to change the framerate of a session is what episoder suggested. Do "File" > "Export" > "Movie...", expand the advanced option, find the setting to override the framerate somewhere, set it to what framerate you want, start an export, and then quickly stop the export again.

Like episoder, I also don't remember how to change it in the Element Viewer... but again, it's arguably easier/simpler/safer to do in the way I explained above.

Note that what was 1 frame at 60 frames per second is 2.5 frames at 24 frames per second, meaning any odd-numbered frame at 60 frames per second will become a fractional amount of frames at 24 frames per second, and any shots starting/ending at a fractional amount of frames will appear red in the Clip Editor to show you something is wrong, so if you have any shots starting/ending at an odd-numbered frame before going from 60 to 24 frames per second, you may want to adjust the timings of some shots a little.
