"best suggestion i have in mind is to make a dctl or lut that clamp the values at interval. So Walter since I've found a solution with the LUT I selected, I don't have a clue of what is going on, except some conceptual understanding of brightness being clamped. ".I've never used resolve but a wild guess would be that it's hinting that those pixels are overbright, above 1." This is interesting because on the Houdini forum I put forth the question of what may be happening and one person said " i bet that is a spike well above the range" So I'm not sure how to 'pick a color and measure'. I'm somewhat still focused on learning to use Houdini. Working in this field of video ( what resovle offers ) is something new to me. The DCI > sRGB to DCI XYZ finally worked for me ( in removing the 'artifact'), after trying several different ones. So I had tried a number of 'LUTS', which is something new to me. I had forgoten that I could right click on my imported media that brings up options. Other thing you can do is change exr types in houdini end experiment how each comes over in resolve. Also you can not use optimised media with multi level. Beter create a separate exr seq per light pass.Īlthough it does work nice technicaly where you can select each of the passes in a multi level exr as masks on nodes etc, nicely implemented i must say. Resolve also does not love (performance wise) multi level exr. Or on the scopes where it looks like a milion dots everywhere. In my case it is alternating lines over the whole screen, like a super fine mesh where every second scanline is white.īest seen by boosting blacklevel otherwise you may miss it. You have to manually set the video range to "full" for each sequence (and optionally set you alpha manually).Īlso if you convert to optimised media, use something like 10 bit or depending on the exr even 16 bit uncompressed (on an ssd raid as disks don't cut it) as anything lower, like not setting full, creates artifacts in current resolve version. Hi, not sure exactly if its what you have, but in all my dealing with houdini exr files (i create lots of simulations in houdini, which i grade in resolve straight from multi layered exr files), there is one thing i found to pay attention to. Help is appreciated - Thank you Attachments Resolve introduces starbursts.jpg (128.06 KiB) Viewed 1617 times I've tried working with as many tools as I can find to make adjustments that perhaps would remove this 'effect' but to know avail. I'm attaching a screen shot that shows what it looks like with the original exr source files created by Houdini rendered in MPlay on the left - and the image of what gets created by Resolve on the right ( of which is a screenshot of the edit window ) of which consequently made me realize that it has nothing to do with what file format I am rendering too but rather how Resovle is 'treating' the incoming exr files. exr files ( uncompressed format ) but this time doing it from Resolve, using Houdinis' exr as source. So then I tried creating another series of. In all cases I used the same resolution the files were create in - 1920 x 1080 HD So I tried avi YUV 422 10-Bit uncompressed and Quicktime DNxHR 444 with the same results of the starburst pattern. I thought because it was a low quality and compressed file format that this was the reason. I noticed a starburst pattern being created in the resulting video clip. I brought those frames into resolve in order to mix with audio and export in a user viewable format like quicktime H.264 I created a series of animation frames in Houdini in. I was hoping someone could tell me what is possibly happening with my resovle renderings.
