I was filming an event, about an hour long. But when I was backing up the files only the first ten minutes had been recorded. The record indicator was on all the time and the time code was also running.

Initially I thought that I had accidently stopped the camera but I had a Gopro taking BTS footage and can clearly see that the camera was in record mode and running the whole time. I don't think the file is corrupted as it's just 2gb and seems to be fine. And I had it set to stop if there's a drop frame.

I was using a BMPCC 4K and a T5 SSD.

Has this happened to anyone else or have an idea what the issue was?

Cheers

If the GoPro shows that the camera monitor displays Timecode in red and running, it seems the camera was recording. But the single small file says the data is missing.

What codec and frame rate were you recording?

My suspicion is that the T5 drive failed. Can’t be sure, but we hear of so many problems with that relatively inexpensive drive, I wish everyone would stop ‘saving’ money and use more reliable media. CFast2 is considerably more expensive, but if you need to save money, be satisfied with a Wise Portable SSD or equivalent Angelbird drive.

If you are on firmware 7.9 make sure to update to 7.9.1 which fixed a problem with USB-C drives.

Don't care about 7.9.2 - there's nothing new for your camera model.

Just a thing: When a user comes to this forum posting about a problem with his recording then in 10 out of 10 cases it's about using a Samsung T5/T7 drive. I know there are some users here using them without any problem for a long time. But the T-series is a consumer drive meant for using it with a computer.

When doing unattended recordings at an event - better invest in quality CFast2.0 cards from Wise or Angelbird. They are more expensive but in the long run will give you much less headaches and less points of failure.
