Don't understand what is happening. .mov and .mp4 changes file type to "FileTypeGroup447". Totally insane.This happens both in FCPX and in finder. Not all files. And a file can show file type .mp4 in finder but shows "FileTypeGroup447". when imported to FCPX.
Mac Studio (2023)
Sorry files shown in screenshot was from Envato but I have checked it is the same phenomena from Envato, Pond5, and Storyblocks. here is a screenshot from finder that also is in the screenshot from fcxp
Sorry but forget about the iphone all files you can see in screenshots are from Envato but the same happens to videofiles from Pond5 and from Storyblocks. Yes i can open the files in FCPX and Quicktime player. This screenshot from finder shows the same.
Please pst screenshots of what you're seeing where.
Can you give more information about the media aside from the file type? Where did it come from? What generated it? Are these original files or have they been converted?
Do the files open and work in the QuickTime Player and in FCP?
Have you renamed these files in FCP because they don't look like iPhone files. Normally iPhone media is imported directly from the phone onto the Mac or AirDropped to the Mac. Is this from your Photos library or somewhere else on your iCloud or is it shared content?
As Tom said, if the file is working in FCP and this is a curiosity question, I wouldn't worry about it.
.mp4 and .mov are file extensions associated with certain "containers", which are organizational methods and metadata schemes used within video files. E.g, Quicktime is a container type. The file extension, container and codec are different things. There are several good tutorials on Youtube which explain codecs and containers. Just search on that term in Youtube.
When using the FCP Event Browser in list view, if you add the column "file type," it displays the container type. MP4 can be confusing because it is both a file extension and a container type, but as used by the FCP Event Browser in list view, it means the container type.
Likewise, the .mov file extension is normally associated with the Quicktime container type.
If you want to know more about your specific files showing the "FileTypeGroup447" as the file type, we would need to see the full metadata readout from that file as presented by MediaInfo. You can Google that to obtain and use it.
Screenshot from FCPX browser. Iphone videos downloaded from icloud. Anyhow I have never seen this before.
See that it is avc1 codec files that changes file type in FCPX to "FileTypeGroup447"
when "reveal in finder" it shows .mp4.
Those files I can see it on just now are preview files from Pond5. Earlier today i hade the same situation in finder with video files from my iphone 15pro.
Please pst screenshots of what you're seeing where.
How did you get the iPhone video from the phone to the Mac?
What Oversion OS is this?

I don't know your process, but if they work in the QT player and FCP I wouldn't worry about it, though probably some metadata is incorrect or has been altered.
