It just seems like Ubuntu is not your best option if you want to edit video, which is unfortunate. Not only have I experienced this firsthand, but I’ve read too many accounts of others within the community also having this same problem to just write it off as something gone wrong on my end. Regardless of whether I’m using Openshot, Kdenline, or anything else, the application never fails to freeze up my entire system shortly after launching, forcing me to do a hard reset. Ultimately I hope this functionality will land in Kdenlive itself at some point.I don’t understand the technical reasons why - whether it be bad drivers, incompatible hardware, or whatever else - but for some reason the Ubuntu OS just doesn’t seem to play nice with video. That's not a problem, they will be overwritten if you re-run the script. the script will leave all temporary files in place after it's done, so you'll have all your partial renders and scripts that made them still there. I made it, becasue I needed it and I wanted to share it with the world, becasue others might want it too.

This is a quick-and dirty script, if you want to use it or improve it - feel free to do so, but don't blame me if it doens't work or it destroys your data. kdenlive-multirender.sh jampack_001.sh jampack_breakpoints.txt 4 Final words Then simply replace the parts number (the second argument) by the name of the file where you put the list of breakpoints.Įxample: bash.
Simply create a txt file with a list of frames where the video can be cut, 1 per line, dont put the frame 0 and the last frame, just the frame numbers where the video can be cut. The breakpoints mode allows you to tell the script where to cut the video. For this reason I have added the breakpoints mode to the script. When trying out this script for music videos I have found that while it is a wonderful time saver, the action of splitting in multiple small videos and sticking togheter after will create audible cuts in the music. Also note that disk I/O might become a bottleneck at some point, because each thread reads different data and writes different data to disk. YMMV - do not try using a ridiculous amount of threads unless you have a ridiculous amount of RAM, or you can fill your RAM and SWAP and just kill your system. On my Rymachine with 16 GB of RAM, a complex 45-minute video saturates my CPU at 6 threads. The first parameter is the script filename, the second one is the amount of parts to split the job into, and the third parameter is the amount of threads you want to process in parallel. Then it will use ffmpeg to concatenate the partial files into single video file. The script will use the original Kdenlive rendering script to create multiple other scripts and run few of them in parallel. kdenlive-multirender.sh Kdenlive-render-script.sh 16 4
#Using kdenlive how to
How to use this toolĬopy kdenlive-multirender.sh into the same directory It's not the most memory or disk-efficient way, but it gets the job done faster, especially if you have lots of RAM and dozens of CPU cores to throw at the problem, and you don't want to wait 12 hours for your hourl-long FullHD video to render. The solutionĪ solution to this is to render out multiplechunks of the project at once and concatenate them later. Blender has scripts like Pulverize to handle this, but I couldn't find anythng for Kdenlive - so I programmed it myself. Rendering videos from Kdenlive doesn't saturate 100% of my CPU power. kdenlive-multirenderĪ Bash script enabling multi-threaded video rendering for Kdenlive. My advice - don't hurt yourself with Kdenlive and use Olive instead. If anyone wants to take it over - let me know.
If you wonder why I decided to switch, watch this video: īecasue of that I am no longer insterested in developing this script. I am no longer using Kdenlive for my video work.
