Footage is 60fps but FCP says it's 58p Hello, i downloaded software on Appstore called "MediaInfo" for me to get some information about the footage i was about to edit. It say it's 60fps at FullHD, but for some reason, if i inspect the video in FCP, it shows only 59.94p. If i try to render the video in 60fps, i would get choppy output (it looks like it's around 30fps). So the only solution i yet found was to render in 59.94p, but still, i can see that some frames are missing (there is like 1sec of "stutter" around every 15 seconds). Project codec is set to: Apple ProRes 4444 Media Inspector inside FCP: Media inspector trough MediaInfo: My render settings: Anyone know what could be the problem and solution? I can provide more information if needed. It's strange for me that there is big stutter when trying to export at 60fps and i am forced to 59.94p, where the stutter is also present (only a little, but still). Thanks for respond in advance! EDIT: i also found more info in FCP about the media, here it says that the footage have 58,82 frames. Strange, because everywhere else it says that the footage is 60fps (also in quicktime inspector). I am running blind here. Origin of the footage is from twitch VOD, downloaded by software called "Twitch Leecher" and it should be at 60fps.

Choppy video playback on videos shot on iPhone X I have a 2012 Macbook Pro. I noticed that with any video shot on my iPhone X, the playback is very choppy in the "Photos" app. At first I thought it was because they were shot in 4K, but I have videos shot in 4K from my old iPhone 6s and they play back fine. Any idea why this happens or if it's possible to fix? I know this is an old machine but it's still pretty powerful.. has 2.7 GHz Intel Core i7 and 16 GB of RAM. Full system specs below.

Why are my iPhone 13 mini camera's Cinematic video, Photo and Portrait modes lagging/stuttering? While using my camera's Cinematic video, Photo and Portrait modes, in the application itself (before taking any videos/photos), the screen lags/stutters a lot. On the other hand, the normal Video mode is smooth as butter (very big difference)! This lagging/stuttering happens in the video itself after I shoot it using the mentioned problematic camera mode - Cinematic mode. I have tried to upload and open such lagging/stuttering video on my computer and it has this issue there as well. It seems the mentioned camera modes just don't work as expected. And also, no, I don't have opened apps in the background... Is this even normal? What could be the problem?
