Hello,
I'm getting an error when I'm trying to export my movie to a file. It gives me a frame reference for the error, so I'm trying to figure out which frame it is, but I don't know how to show frame numbers. I've looked in past discussions (which are all several years old), but the responses refer parts of the UI that seem to have been changed.
Thanks in advance for your help.

Hi, chschen,
iMovie doesn't display frames or frame rates.
However, here is a link to a frame to time converter so you can precisely locate the specific corrupt frame:
https://www.zapstudio.net/framecalc/
You will need the frame rate of your project to enter into the converter in order for it to make the calculation. Then you enter the frame number given in the error message. The frame rate of your project will be the frame rate of the very first video clip (not photo) that you placed into the newly created project. The converter will give you the time point in the timeline at which the corrupt frame is located. That's the area that you want to scroll around to see if you can find any black frames, white flashes, artifacts, fuzziness, or other corruption that you can remove.

Here's a link to Apple's help menu discussion about frame rates:

Technically, the frame rate of the project will be set at the frame rate of the first video clip added, unless you have "Apply Slow Motion Automatically" checked in the iMovie preferences box. In that case, a 60fps clip that is inserted into a 30fps project will be played in slow motion (30 fps) to conform to the 30 fps project. According to Apple's help discussion, to preserve the original pitch of the audio, select the Preserve Pitch checkbox above the viewer.
I have found that iMovie will reduce a 4k 60 fps clip to 4k 30 fps when added to a project, so in that case the project would be 30 fps if the 4k 60 fps clip were the first added clip.
As an experiment, I created a new project and added a 25 fps clip as the first clip, then followed by a 30 fps clip and a 16 fps clip. All of the clips then were played at 25 fps in the project. Also, the project shared out at 25 fps.
After a project's frame rate is set you can manually vary the speed of specific clips with the speed adjustment tool.
EDIT: For best results it has been recommended to use clips that are all of the same frame rate in a project.

Thanks for your helpful response, Rich!
I used a lot of different clips taken from different devices. Perhaps they all use the same frame rate, but, out of curiosity, if they don't, then does iMovie convert everything to use the same frame rate as the first clip?
Sorry if the answer is obvious. I'm a complete newbie at film editing.
How do I go to a specific frame in iMovie?
