Davinci resolve and Sony A1 footage

Hi, I have been using Davinci resolve for my video editing with my Sony A9 II camera (4K 10Bit 100Mbps files). I recently got the A1 and shot some video that I want to process now. I shot both 8K and 4K (10bit 200Mbps). the footage plays back just fine in widows 10 but as soon as I import into Davinci I see these weird color bands. they appear at the few second start of each clip in timeline and render same in the output. re-installed Davinci few times, same issue.

appreciate any pointers

Care you share a problem clip for testing?

File is too large not sure how to share

This is Sony XVAC H type file I believe it is based on HEVC I tried converting to resolve optimal format in media pool but did not help

Simply put it on a cloud service and post the link here.

doesn't work, the forum doesn't allow my to post URL's

I tested a few cases and it seems like the color strips appear only in XAVC HS format. it is kind of random it happens for some clips and not for the rest. in all cases the playback has no problem both on Windows 10, Mac OS Big Sur or the back of the camera.

system spec's Core i9 10 core 128GB DDR4 RAM 4TB NVMe SSD 2 x GTX 1080 GB each. Tower has water cooling and never heats up above 55C.

does the paid version support these files without creating artifacts ?


looks like windows/mac cannot decode the 4:2:2 format, neither does Davinci. does anyone know what kind of codes are required for these files ?

Playing fine here in an UHD timeline on my iMac and even on my wife's MB Air M1 (with some stuttering).

I'd assume a GPU hardware or GPU driver issue.

I'm also not seeing any issues with the media in Studio 17.1.1 for Windows using an 8Gb GTX 1070 with Gaming driver 465.89.

that is strange indeed I have 461.92 studio driver, perhaps that makes a difference ?

I have the same driver, no issues here. Win 10, Nvidia 1060 6 GB, Studio 17.1.1

I would then consider a faulty GPU.

I downloaded Adobe Premier pro and was able to open and render the files with no issues, must be something corrupted in Resolve. I tried using one GPU at a time, but no difference.

What GPU's are installed?

2x GTX 1080

one thing I haven't tried is to remove one card entirely to disable SLI driver. Is anyone running Resolve with Nvidia SLI setup ?

I was able to find a half-ass workaround, if I use Sony's own catalyst browser to transcode the files to the same format it goes away also! but this program cashes after transcoding a few clips and it's useless as part of a workflow

I also tried on my MBP 16", no issue there but of course very slow to handle the 8K files... so it seems to have to do something with the graphic driver....why just the first 1-2 seconds though

Don't remove the card, but disable SLI. Resolve is not compatible with it. 99% it's the culprit.

Same problem of color bands in 8k Sony A1 clips ONLY in resolve not elsewhere on the computer. I have an Nvidia GeForce GTX 1650 Ti with driver version: 27.21.14.6647

just checking to see if there has been any solution to this problem...still having the same issue. have to use macbookpro (really slow) for processing A1 videos, with the GPU shortage and crazy prices switching to newer GPU's is not a wise choice right now...

I am considering purchasing a license for the paid version of Resolve. But I too, am having the same issues with the banding. Has there been a solution to this? I have a Window 10 PC (Dell XPS 8930, 64Gb Ram, Intel I-7, Nvidia GTX 2030). I will be sending a screenshoot and recording of this. I've recorded on the Sony A7iv with the h.265 10bit 4:2:2 codec. I even tried 50mb and 100mb and it made no difference. I still have issue.

I really hope there is a solution to the problem. It really makes no sense. I can watch the video with no issues on the standard Windows media player with no issues, but as soon as I take the footage into Resolve that is when I see the banding.

If you can post a sample, I can try it on a Mac.

From what I am gathering, Mac users do not seem to be affected by this weird phenomenon. Here is the link to files and screenshot of what I am seeing on my end.

Were you able to get any help on this? I've started a new thread because I am having the same issues that you described here.

Well, the first clip plays fine on my Mac, but the second one (window closed) has a problem. It shows "Media Offline" from TC 03:26:02:23 to 03:26:04:19. The rest is fine again.

Hey, I am new to daVinci, and I encountered the same banding issue with sony a1 footage. This also happened in Premiere elements, but not in Pinnacle Studio nor Windows media players. I updated my device drivers but didn't resolve the issue. I'm using windows version.
Thank you for your help

I also have the same issue with my Sony A1 footage on Davinci Resolve 18.1, shooting 4K 60fps 150mbs 10 bit 4.2.0 . Strange glitchy banding, not on all clips and not all the way through the clips. Nvidia GeForce GTX1060 3GB, updated driver 31.0.15.3168. Seems to primarily affect clips with detailed subjects moving rapidly, but as a wildlife photographer, that's kind of important. All of these clips play flawlessly with VLC and all other media players on my Windows 11 machine.

Wondering if anyone has figured out a workaround and/or whether paid version works with these Sony a1 clips.

Just for everyone's benefit that may be facing the same issue, I went ahead and bit the bullet yesterday and bought Davinci Resolve Studio 18.1 and can confirm that the paid version can digest and process Sony A1 10 bit 4.2.0 and 4.2.2 with no issues.

Hey, Jeffrey.
Just want to follow up with you. Has this issue been resolved with the full version? Planning to upgrade if so. Thanks.
