I've run into an issue that I've never seen before, and I haven't been able to find any discussion about it either.
I shot a video recently in BRAW on my Pocket 4K, and edited it in Resolve. On day one of editing, I watched through all of the footage in a timeline and there were no issues. On day two, I discovered that two sections of one clip were corrupted, and I am 100% sure they weren't before (there are literally clips in the timeline that I put in on day one that are in a video track directly above one of the sections that I found corrupted later).
The corrupted sections flash between the footage overlaid with rows of vertical square pink dots and the occasional horizontal pink line, and the Resolve "media offline" screen. Some frames also look like an split screen between the current frame and one from later in the clip, usually also with the dots. Rebooting the program didn't fix anything and neither did installing the latest update. I thought it might be an issue with my hard drive so I copied the footage over to another one, and that didn't solve it either.
It's the third day I'm editing, and I just opened up the project to find that a third section, this time part of a different clip, is now corrupted in the same way. I'm worried that this is going to continue and I have no idea what to do.
Here's a YouTube link to an export of the first corrupted section because the file was too large to attach. I think this calls for an epilepsy warning.
Has anyone seen this before? Thanks in advance.
Edit: I submitted my clip through Treasured by Aero Quartet so they could have a professional look at it (I highly recommend this, the inspection is free and then you can hire them to repair it if possible). They said the affected parts contain "about 20 to 25% of empty data (those white blocks in the attached pic), producing those issues." I attached the image they sent for reference, though I don't know much about how to interpret it. They also said that this is typically due either a lack of speed of the card/drive used during the recording or a bug in camera's firmware (but if that was the case all files should behave the same). I have a Samsung T5 and the write speed is easily high enough to accommodate my 12:1 compression DCI footage (and I speed tested to make sure it hasn't worn down over the years), but the cord that I've been using has gotten kind of bent out of shape so it's pretty plausible that that's the problem. I'm going to replace it and run some more tests, and replace the T5 if that doesn't work. I hope this helps anyone else affected.
