Project Framerate doesn't match Comp Framerate

[AE_N00B]

As shown in the screenshot, my footage and comp are at 29.97fps, but the whole project is rendering and previewing at 50fps.

I changed this somehow a while ago when I was shooting 50fps on my camera, and I can't work out how to change it back.

I fixed this by uninstalling and reinstalling After Effects. (I can't work out any other way of doing it)

You can set the preview frame rate in the Preview panel - it's likely yours was manually set to 50 from your previous usage. 

Without seeing more of your system info (that seemingly no longer exists anyway, it's hard to diagnose beyond this. Guessing you may have also been using an export preset (one you made, perhaps?) that had the frame rate manually set at 50fps. 

If you opted to wipe the AE Preferences when doing your reinstall, I would assume that's actually what fixed this. In the future, you can reset your preferences by holding CTRL+ALT+SHIFT / CMD+OPT+SHIFT while AE is starting, and then following the prompts. Quicker than reinstalling!

Thanks so much! I knew I'd set it somewhere, but I couldn't find the panel.
