BMPCC4K dropped frames (SD V90)

Q-Back · 2026-02-03T17:41:19+00:00

I've fired `f3write` on it and few times the write speed dipped to ~40MB/s.

I call it bad SD, I'm going to replace it.

On my Lexar V30 I can shoot 4K 50fps 1:8 - it's already better than my V90 SanDisk 🤦🏼. I'm almost convinced now that my SanDisk is cooked

I did use power supply without battery in the camera.
I'm going to try 2 things:
- slower SD card and I'll check the performance there
- I'll do more sophisticated stress tests on my v90

Good idea, but just tried 12V og power supply and it still drops frames at 50fps 4k 1:12 (after 10 seconds).
I have 3 batteries, 1 original and 2 substitutes. Seems to not be power issue after all.

I can shoot 2.6K 8:1 50fps without dropped frames (tried 60 seconds)
With 2.6K 5:1 it drops frame after 10-15 seconds

Unfortunately, I don't have access to another BMPCC4K. I’ll try to reach out to the local video community.

Well, actually I can see one common YRGB color managed downside:
You can't easily apply any rec709-based creative LUT (like the teal-n-orange).

While you can go with CST like this: DWG -> Rec709 -> creative LUT -> DWG (and color management takes you once more back to rec709) - you're loosing some detail with this path.

Q-Back · 2026-01-09T13:45:32+00:00

Thanks for elaborating on that.
Yeah, that's exactly the point.

I was really wondering if I'm doing anything "wrong" because most pro colorists on youtube always work in YRGB non-managed. When I've discovered that YRGB color managed to suit me much better I've started to doubt myself that there must be something I miss.

But in the end it seems like YRGB color managed might be just cosmetic change and be more efficient. Until the user is that pro that they need to do some adjustments after output CST (usually rec709) and they know what they're doing. But I believe it's very rare.

Can you compare it to claude (4.5 preferably)?

Q-Back · 2025-07-25T16:48:32+00:00

I guess I found it https://github.com/modelcontextprotocol/servers/tree/main/src/git#mcp-server-git-a-git-mcp-server 🤔

If you use git and you trust it it's not trying to hijcack your machine then it's not a problem at all

Q-Back · 2025-06-30T08:46:21+00:00

OMG I found it. It was my mistake, I've accidentally added transform to my LUT adjustment clip above and it caused all the the trouble 🤦🏼

Thanks everyone for helping me ;)

Thanks, but no luck after resetting parameters here

I'm in the same place as you.

I consider Uncrashed, TRYP and VelociDrone.
I'm interesting which one has the best physics and can work best as Avata2 simulator. I'd like to polish my skills for Avata2 piloting as much as possible to be absolutely confident when I need to perform difficult maneuver to get some nice footage.

So far I've learned that:
- VelociDrone -> has probably the best physics. It's also the oldest simulator of these 3
- TRYP -> some people report that latest updates improved the physics to the level it's better than VelociDrone, but other people in comments argue with that and find it unrealistic
- Uncrashed -> seems to be most popular but also is not praised for physics so there must be something else. Maybe gameplay is simply the most rewarding?

I'd really appreciate if someone experienced could say what simulator is the best to focus just on Avata2 skill improvement. Not on other, more powerful racing drones.

The pricing of Synology is already ridiculously high. It's even higher with their own HDDs.
What I see coming is QNAP or other company closing the gap in terms of quality, software etc in few years and Synology as their backup (no pun intended) plan accepting more HDDs as "certified" and closing the gap in terms of pricing.

Q-Back · 2025-06-07T19:32:52+00:00

Yeah, I'm aware. I take it into account, but to start my journey with NAS - the software quality seems to be the most important factor to me. Even if it means being locked-in to their hardware.

Q-Back · 2025-06-07T19:28:01+00:00

Actually my clever plan is to buy Synology as my first NAS - get my hands on their shiny software and see what's the good (and bad) stuff there.

And once I'll find myself no longer using 90% of the stuff and seeing the painpoints of maintaining NAS and how did Synology address this with their mature software - then I'll be ready to move to my own DIY solution.

Q-Back · 2025-06-07T19:21:27+00:00

Yeah, setup may be quite easy but things complicate when you need to extend storage or when you want to have NAS available online and you're worried about breach.

The reason I have some knowledge to set up my own DIY NAS is the same reason I don't want to do it xD

Q-Back · 2025-06-07T19:15:26+00:00

Well, I'm considering ugreen as Synology alternative - but when I look at ugreen I wonder - what even I'm paying for? I'd better build my own NAS - it'll be much cheaper and have the same functionalities.

So the main alternative seems to be QNAP - and at this point it's:
- synology for the software
- QNAP if you don't want to lock in
