Serious bug, DR makes source footage corrupt

Dit you made this screenshot? The glitch is on another place than at my system. Thats strange.

yes, macpro 5,1 big sur radeonVII and BRAW player 2.1beta 3

but i dit not search for other glitches

and also a angelbird CFast2.0 card can be defective!

Hi,

Here is an update. The disk drive is OK. I tried it with a new card, new card reader, new SSD drive. Unplugged all other devices. The problem is still there. So Blackmagic, please let me know how to fix this problem.

BR, Robert

Just brainstorming but check if you have not set any intermediate/proxy/render cache etc destinations to the same destination as the source clips.
That is in my eye the only way to accidentaly damage source files by Resolve while editing/grading.

A second red flag to check out would be that you mentioned a drive connected via thuderbolt. Anyther minefield of potential problems resulting in corruot files on write. Cables, multiple TB masters conflic, connectors, other crazy devices in the TB chain messing with your drive.

I checked everything. It is not DaVinci Resolve. Also the BRAW player makes the files corrupt. Also have this on the main disk.

i think you have a drive problem
the player does nothing exept playback > no safe

I would throw my entire system in the trashcan if multiple software corrupts multiple files on multiple drives.
Corrupt hardware , maybe memory , but could be so many things by now, or worsr case a virus that corrupts every file you touch.
No logic in what you experience anymore other than your entire system can'r be trusted at all anymore.

Start with formatting and reinstall your OS from scratch. You need to make large steps and systematic analysis to find what is going on at this stage. For sure its 100 % your system and not resolve or raw player or anything like that.

I've only once seen such glitches and that was with a bad reader. But from what you describe, we can exclude that.
So, I tend to second the radical solution Glenn suggested.

Just did a fresh install with OSX bigSur. Now I I installed Resolve Studio and when I want to open the program I get this message: You are not allowed to access the DaVinci Resolve app.


Why?

I can open the program now. Now I get an error when insert the activation key... Argggg.

I have a fresh install, still got the same problem. Blackmagic ? Where is the support?

Blackmagic ? Where is the support?

There's no reason to think it's their problem rather than your hardware.

It's BigSur related. Are you installing Resolve which is compatible with it?
Follow all on screen prompts and give permission when required.

Shotput pro will generate checksums. That's one of the reasons to use it. You can change how it works, but I think by default it runs a checksum on both the source and destination, and makes sure they match. It will write the report either inside the destination (which will change the checksum of the result), or write the report somewhere else so you always have a record of the card's checksum in its original state, before any other software has touched it.

At least now you know , with a fresh install confirming its not some crazy software bug or corruption, its 100% somewhere in your hardware.
With gazilions of users and zero comparable issues ever, nor any logical software component that would ever even get close touching source files, exluding the mentioned option of you setting the cache/proxy/reder or any other target location to the location of your source files, its not Resolve so not BM to help you here.
The absolute confirmation of that was the fact that you mentioned the BRRaw player corruption your files.
Only a virus or a broken OS (hence my suggestion to wipe and reinstall OS) could make a player corrupt your files via software.

It is also the problem of Blackmagic, this mac is one year old and was recommended by Blackmagic.

1. Every other codec = zero problems editing
2. Only BRAW footage is unstable.

So just blame it on the hardware? What do you think Apple is saying to me? They Will scan the iMac and tell me there are no problems. It is the software that is faulty.

I was a big Blackmagic fan, but this BRAW codec is so unstable, so when a system has any “hardware problems”, the footage will get corrupt. It is a big shame that Blackmagic won’t help me. I was one of the first users that shot a feauture film with it. If Blackmagic is serious about their business and if they want to level up in the film industry than they should help me with this. If not? Then the BRAW codec is in my opinion a Mickey Mouse codec. BRAW is great if it works, but if you have any problem with it, don’t contact Blackmagic, we only sell camera’s and take money. Just figure it out by yourself. Blackmagic is not the problem, but your other hardware is. I’m sick how they treath their customers like they are pets.

So if someone is planning to get in the BRAW eco-system, I don’t recommend to do. It maybe looks like a good deal for such a cheap camera. But in the end, you pay the bill. Better spending a bit more and get a real pro level camera.

My opinion about BRAW codec:
If you are a professional filmmaker? Look further for other camera brands like Canon/Sony/RED. Simply because BRAW is a codec you can’t trust. And in filmmaking world there is nothing more important that you can trust your gear.

I have worked a lot with professional Sony camera’s for years, never had corrupt footage. And if their was a problem, they fix it as soon as possible. So we can continue shooting because that’s our business where we earn money. When I have a problem with Blackmagic, no one hears me. This forum is great because of all the good people that want to help me which I’m very thankfull. But I think this problem is a lot deeper. I contacted blackmagic also directly, they never told me what the real problem is. They have all the crash reports that they asked for but I think they can’t even read them or they are lazy to do.

I just pulled the trigger and invested in a new Apple system. Just because I have to finish my projects. When they are done I’m selling all my Blackmagic camera’s and getting out of the BRAW system. Simply because this is not a workflow that I trust anymore.

I want to thank all the nice people here at this forum that helped me.

I can understand your frustration, but there is definitely something wrong with your configuration or hardware. We have three BM cameras at a film academy, next to Arris, Reds, Sonys.
Students shoot BRAW and grade in Resolve and I've never seen such an issue (apart from the one bad reader I mentioned).

Sad to see you go, you may be missing the good stuff this ecosystem has to offer.

Stop whining and blaming others for your failure to diagnose basic hardware issues.

You can always mount your footage read only to exclude any possibility of anything changing it.

This is basic computer knowledge. If you can't do it, pay someone to help you and move on with your business.

You can have your opinion.
Problem is that 1000s of other BM camera users simply won’t agree with you as your case is an isolated incident which proves nothing ( based on your descriptions and taken actions).
It’s same as saying - I got flat tire, so I think my new car is rubbish and useless. I will never buy it again.

You can always mount your footage read only to exclude any possibility of anything changing it.

Did that, again corrupt footage.

Thats the point where you loose any further help from anyone serious here as you just proved yourself that it is NOT blackmagics software at fault as a read only mounted storage can not be touched by software. So it helps if you can undersand and interpret the results of your own testing at least.
We are typicaly super helpfull bunch but we have to assume some basic and reasonable troubleshooting skills. And based on all we get back from you sofar there is no serious helpfull way anymore to help. Sorry.

Which is 100% proof that it has nothing to do with any software (not just BM), but some system/hardware issue.

I did a last test. Clean install with Catalina 10.15.7, Davinci 16.2.8.005

Testing it for 4 hours now and I've got zero glitches and no corrupt footage.

Cool, that is progress. Still hope you figure it all out eventualy.
If it works, dont change anything !

Not specific for this tests

Had something like OPs initially described problem this week. Even Blackmagic player showed digital artefacts in .braw files at the same timestamp as in Davinci Resolve. Copying "damaged" files to another computer brought the "damage" over as well.

Check connectivity, e.g. always connect external disks or HDD docks straight to motherboard ports, check if HDDs are inserted properly, and check cable integrity!

In my case, HDD docking stations were connected to a Mac Mini via Thunderbolt to USB hub. The problem was solved on the spot after reconnecting straight to USB-A ports.
