On import, Capture One assigns incorrect image date/time on VIDEO files
When importing images I typically use naming tokens to assign a new file name which includes the image capture date and time. Recently, I find that Capture One assigns an incorrect date/time on my VIDEO files. It does not make this date/time error on photo/image files. In my case the date/time Capture One assigns is 5 hours ahead of my local time. I'm in the North American Eastern Standard Time zone (GMT-5). It feels as if Capture One is somehow misinterpreting the offset to GMT?
I cannot find a preference setting or any way to adjust this import process to correct the error in Capture One.
I've double-checked that my computer clock is correct. I've double-checked that the original image capture files do have the correct date/time in metadata for their actual file creation date/time. Why is Capture One assigning an incorrect date/time on import? And is there a way to fix this?

No. These files were captured and are being imported all within the same time zone.
In digging further I find that Capture One is handling the file naming of image (photo) files accurately but this is happening just on my video files, from multiple different cameras/camera manufacturers. CO is consistently renaming the imported video files and assigning a date/time 5 hours in the future.

What is the time zone setting in the camera? Capture One may be honoring that time zone setting if it is set to a time zone that is 5 hours earlier than your local time zone (eg GMT vs US/Eastern).

Walter Rowe the time zone on all cameras (this is happening on video files from multiple different cameras and camera manufacturers) are all set to my local time zone, same as the computer being used for import.
Hence, the date/time reflected in the original camera capture files matches, as mentioned in the OP.

@... thank you for that information.
Thing is, I've checked the date/time for the file in the file system and it is accurate to the actual capture date/time in my time zone, while the files imported via Capture One push that time 5 hours ahead.
I just submitted my own bug report on the issue. I expect they'll tell me to update as I'm a version behind. Then that will likely be it. :(

FWIW, there is a GUI written for EXIFTOOL that can help with time and date changes in certain circumstances: https://exiftool.org/gui/
Also, in the case of videos from my Sony a1, when the embedded metadata output from exiftool does not explicitly include a GMT offset, the time is listed as GMT. For example:
Create Date : 2023:12:27 20:04:55
Modify Date : 2023:12:27 20:04:55
Track Create Date : 2023:12:27 20:04:55
Track Modify Date : 2023:12:27 20:04:55
Media Create Date : 2023:12:27 20:04:55
Media Modify Date : 2023:12:27 20:04:55
Last Update : 2023:12:27 12:04:55-08:00
Creation Date Value : 2023:12:27 12:04:55-08:00I don't know if this is part of the standard for video metadata, if one exists.

@... - Thank you. I did see your offer earlier but have been away from my office most of the day. I'm sending you an email. I'll be interested to see what you may find.

@..., oh, and also, when I said earlier I figured Capture One support would tell me to update my application and that would be it. I wasn't thinking the update would fix the issue but rather that they'd leave it at that and further support would be unlikely... cynical I guess.

Files DJI_0544.MP4 and C0001.MP4 are original, unedited files from their respective cameras, a DJI Mavic 3 and a Sony a6500.
The other two files are generated on my iMac Pro by importing the originals through Capture One Pro and using file naming tokens on import to establish the imported file names. I don't believe any of the metadata you see is changed or inaccurate from the original capture files. It's just Capture One's application of dates/times in the output filenames that are not as expected or intended. There was no editing done in Capture One, just a file import.
The import filename tokens used in Capture One Pro were:
"Image Year (yyyy)-Image Month (MM)-Image Day of Month (dd) Image Time (HH-mm-ss)"
All images were captured in the Eastern Standard Time zone (GMT-5). The iMac and both capture cameras are set to the same time zone. One error I found in double-checking is that the Sony camera had the DST setting incorrect so its clock function was one hour off at the time. The Sony capture (C0001.MP4) was set one hour ahead.
The [File:System] dates/times you see in that metadata match the time earlier today that I copied those files into the Dropbox folder where you accessed them remotely.
The DJI original video file named "DJI_0544.MP4" was captured on December 14, 2023 at 10:45PM EST
The Sony original video file named "C0001.MP4" was captured on January 1, 2024 at 12:16PM EST Remember though that this is the camera which had the DST setting incorrect so the camera recorded a capture time of day as 1:16PM EST.

All that said, it appears the "Create" and "Modify" timestamps you found in metadata are accurate to Greenwich Mean Time (GMT). The Sony camera appears to make a reference to the time zone adjustment while the DJI camera doesn't.
Capture One seems to create my filenames using the metadata and no regard for time zone adjustment from my computer or otherwise...
