DaVinci Resolve 16 -- feedback


Anyone using DaVinci Resolve 16 (free or Studio) on Slackware 14.2 or -current? Any major problems, issues to report?

I have an 8-core AMD processor and I can use either a mid-level AMD GPU or a mid-level Nvidia GPU. Sound card is external USB.

I've been using Resolve 15 on an iMac for a while. It relies heavily on NVidias CUDA drivers to achieve a reasonable level of performance, which is unfortunate as Apple and NVidia seem to have fallen out! CUDA drivers on a Mac are a pain in the posterior to get right, and without them, Resolve slows to a crawl! This isn't helped by the fact that, despite the price, Macs are seriously under-resourced! The only good thing about them is the monitor, which is superb!

Resolve can work with OpenCl, but CUDA performance is much better - even on low to mid-range NVidia graphics cards, such as those in the Mac. I would therefore recommend going the NVidia route, even if its a lower spec card! (And I'm not normally a fan of NVidia!) Just make sure to install the proprietary drivers and CUDA!

I haven't tried it on Slackware, as my main machine uses Intel graphics, and for most stuff I find Kdenlive quite adequate (comes with AlienBob's Plasma 5 installation). Resolve is definitely much better than Kdenlive when it comes to importing and handling still graphics and for handling speed changes (select "optical flow"!), but otherwise, there's not much in it. Kdenlive is much less resource intense. I would recommend plenty of RAM (16GB or so - the Mac struggles with 4GB!)

I believe the Linux version of Resolve is missing some functionality - at least the website says it is - but I'm not sure how much this would impact on non-professional use. (I'm a retired broadcast video editor). Also, Resolve 15 (haven't checked 16) is aimed squarely at CentOS and seems to require some ugly hacks to get it to work on other systems. However, someone has written a script to create a deb install for 'buntu's ( https://www.linuxuprising.com/2018/0...lve-15-in.html ) which could perhaps then be converted with deb2tgz to simplify a Slackware install.

I'd love to know how you get on with this, as its something I've been thinking about for a while. However, I've decided to put it off until Slackware 15 is finally released - hopefully with Plasma 5 included.

Please keep us informed!

Cheers,

Well, thank you Pete. An informative and somewhat disappointing insight. I'm just a casual user of video editing software, but on Linux they all seem to have a flaw - instability or lack of features or slow rendering or something - which makes even casual use frustrating. It seemed Resolve might finally be the answer but, as always on Linux, complications! Then again, I'm very surprised to read that the Mac is no better. So back to one of the others then - Blender (quite good but slow rendering), Shotcut, Cinelerra or Flowblade. I've had too many quarrels with KDE/Plasma now to consider Kdenlive for long-term use.

Gerard, I wouldn't be too despondent! By far the easiest route is to 1) upgrade to Slackware-current and 2) apply AlienBob's Plasma 5. It might seem a bit of a faff, but 14.2 is well past its sell-by date and the above combination is rock-solid!

Kdenlive in Plasma 5 is very stable - I've yet to have it crash. You will probably have to install libx264 and libx265, and rebuild ffmpeg with these enabled (both trivial to do), as I'm not sure whether the Plasma 5 comes with these enabled in kdenlive. Probably not due to copyright issues. I already had them on my system before I upgraded, so I can't comment on what you will get without them. Then its just a case of removing kde4 completely, and installing AlienBob's Plasma 5 packages. This is easiest done using SlackpkgPlus, and Eric has a very good "idiot's guide" on his website: https://alien.slackbook.org/blog/

Here's a little piece I put together a couple of years ago on kdenlive. Nothing spectacular, but it proves it works!

Well, that had me in stitches! Very funny! Model aircraft is a hobby that brings me right back to the 80s myself, although I never had engines in my models, and indeed I turned to building medium- and shortwave radios instead, not long afterwards. The things we used to get up to with just one channel on TV, no computers and no internet!

I don't have problems with stability regarding Plasma 5 on -current. Just annoying issues with regard to the panel, which has long been a bone of contention for me. But I can - and might - use kdenlive in icewm instead. Having said that, I've a soft spot for Cinelerra, ugly interface notwithstanding. Or perhaps all I need is Shotcut? The only thing I am sure of is that I am gradually coming to terms with the idea that audio-visual is the best way to get ideas across to young people, whose concentration span is about 5 minutes. Exciting in some ways, disappointing in others, if pen and paper have always been your tools.

I don't need professional tools to produce the videos I have in mind, but in 2019, going on 2020, it's sad to think Linux still hasn't quite delivered on its promise after all these decades.

Thank you Pete. I'll keep you posted.

There's a thread here https://forum.blackmagicdesign.com/v...ada&start=1500 that started in 2017 and catalogs the 1,000 sorrows of Linux users trying to get Resolve working. The only supported distro is Centos, although I think Ubuntu and Debian installs are well documented by users. I personally have performed a successful Centos Davinci install (it's not difficult), but an attempt on Arch Linux become a rabbit hole of pointless suffering.

In my case, getting Davinci working was only part of the battle. I had trouble getting my audio hardware to work in Centos and of course Windows plugins that I needed would have required additional workarounds or substitutions.
