really? how do we submit a bug report? theres no obvious way on blackmagics website.

The “get a tower” snobs on here are getting old.

How about “real answer” some of us have towers, but we also want to set grades while still on set using a macbook pro and thunderbolt array, an ultrastudio minimonitor and a 2nd connection to the directors broadcast monitor. Then we copy the setups to a tower to finish the job.

So you can make Resolve faster for laptop use. Go into project settings, set your sequence resolution to 720p instead of 1080p, set scaling to “bilinear” instead of “smooth”, if you’re working with R3D then set debayer to 1/4 resolution.

Turn off render cache while setting grades interactively, then turn it on to let it render the timeline to dpx to see a preview., then off again when you tweak grades. Having render cache on introduces a huge lag while trying to adjust grades if it’s also rendering in the background.

resolve can be much faster on a laptop using these steps.

versions doesn’t work for me, I made my look node as 3rd node. add a new version, modify the colors, then when you change back to a previous version it only changes that clip, not all the clips in the group.

the only way I’ve found that works is adding multiple parallel nodes of the look node then toggling them on and off to show the different versions of my look grade.

That works but seems a little convoluted.

ok sorry I missed this post before I posted again.

so how do you recommend setting up things to be able to show clients multiple versions of a look when working with groups?

lets say I have 3 nodes, base grade, vignette then a look grade all my clips in groups. I want to have 3 looks setup and be able to change between them and have them update to all clips in that group only for the look node?

no one seeing this as well?

the same thing seems to happen with any undo when you have groups. If I add a new serial node, then undo that I also lose all the grade settings in my primary node (all get set to values from first clip in group).

using versions with groups doesn’t work either, when you change the grade to a new version it doesn’t change the corresponding node in the rest of the clips in a group.

The only way I’ve found of having multiple grade setups to show the client using groups is using memory/store/restore, that seems to work correctly and doesn’t messup all my primary balance grades.

what? Smoke and Premiere Pro both use CUDA and/or OpenCL. Not it’s not totally different.

You want to collapse all the color operations to a single 3D lut and apply it in realtime using the GPU. People have been doing that in realtime on 2K footage since the very first version of Lustre in 2001 LONG before OpenCL or CUDA existed.

A modern laptop has the graphics grunt to do it, if you write the code for that specific chipset. For whatever reason Davinci hasn’t chosen to do that.

Yes, except the same laptop can do realtime playback and decent interactive performance with smoke and plenty of realtime effects in FCP X and Premiere Pro on HD 1080p footage. if its weak then its weak because Davinci haven’t optimized the code as well as Autodesk, Adobe and Apple have.

Thanks peter, 720p helped a little but its still lagging. I’m a little disappointed since this system with pegasus array is pretty fast for smoke. realtime uncompressed 2K playback is not a problem in Smoke and the GUI updates smoothly.

I can’t seem to even get realtime playback of h264 files on the timeline with no color grading applied. Is there any way in Resolve to pre-render the timeline to a format that it likes to work with to speed up future processing?

In smoke I can conform a mixed codec timeline, hit process on the whole timeline, go have a coffee, then the entire timeline gets rendered to smokes native DPX format and from that point on it plays fast and is fast to work with interactively.

Anything similar in Resolve?

thanks very much, ok will try that workflow of spitting out DNxHD directly from Redcine. sounds simpler

I did try using prores lt 720p proxies from Redcine into Avid… no luck, avid was changing the timecodes when converting the quicktime files into media composer and resolve spat out “timecode extents does not match” on every single clip when I exported an AAF.

we need prores proxies for other uses anyway, wish avid could work from those, but it seems its not to be so I need to batch both a prores 720p lt and an MXF from each R3D file.

Ok solved… in my case think it was some specific dodgy R3D clips that caused the problem. I was creating a test edit in avid using R3D files I downloaded off the net. 3 files always get “time code extents does not match”, the rest of the files seem to work ok.

they’re all 23.976 fps, but might be some issue with Red camera firmware etc…
