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 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. So let us see if I continue using kdenlive in future.I am no longer using Kdenlive for my video work. I believe it took 17m to render the 5m video which is not super fast but acceptable. I edited these videos that I recorded from my DSLR on full HD 50 fps and used Arch Linux running on my beloved ThinkPad x220. For my editing needs I don't really need too much honestly. I think I will stick to kdenlive for a while. I tend to get too involved in it because I think I want to create a good video but at the same time I don't like spending too much time editing videos and that is why I use OBS to record 99% of my videos. Although I have love and hate relationship with editing videos. I do have lot of experience editing video so I guess that's why I was able to pick up quite easily. So overall I think I spent 20m to do all that. I learnt how to fade in, fade out and dissolve both audio and video.I learnt how to change the audio level of a clip.I learnt how to export or render the clip.You can remove one space or all the spaces. Remove spaces: There is an option in the timeline.Cut the clip: Use Shift + R where you have the timeline.How to import video clips from local drive? There is an option to import. How to use proxy videos? It is a simple setting in the configuration.In this videos I did the following things or you can say I learned the following. So I just edited this video using #kdenlive and it didn't take me long to figure out basic things.
