Kdenlive, that video editor available for our Linux system is one of (in my clear opinion) the wonders of applications that we have available to use.
Years ago when I was still a Windows user I used TMPGEnc to cut videos, thus eliminating commercials or whatever I wanted. Today with Kdenlive I can cut pieces of a video, but I can also change the audio, add effects, etc, all this in a very simple and intuitive way.
Table of Contents
It has never been so simple, search your official repository for the kdenlive package and install it.
In ArchLinux it would be:
sudo pacman -S kdenlive
In Debian, Ubuntu and derivatives it would be:
sudo apt-get install kdenlive
Opening Kdenlive for the first time
When we open Kdenlive for the first time we will be shown a configuration wizard, it will check if we have everything we need installed (such as vlc and ffmpeg), it will ask us what video profile we want to use, if we have a webcam, etc. Here are several images about it:
Once open we will see something like this:
That is our workspace. Above we see the Menu (File, Edit, Project, etc.), below 3 areas that from left to right contain: Space through which multimedia files can be added to the project, the video player in use, and finally to the right, the player through which the complete project is previewed.
Further down we find the project timeline, that is, the large rectangle through which we put the videos or photos we want in the order of appearance we want. In the left part of this area we will see that it says something like "Video 1", "Video 2", "Audio 1", etc, this means that we can add several videos, several audios, not limit ourselves to just one.
Adding and cutting a video
To add a video and use it later we must click on the button with the plus symbol (+) that is in the area on the left above. Remember when I mentioned just above that there was a space through which multimedia files are added? … Well, the + is in that area, click on it and a window will open that will allow you to search for the desired video.
When they add it, a small window will appear possibly telling them that the video does not comply with the profile they selected at the beginning, it does not matter, they give Update Profile and that's it:
It will appear in that same box or area, simply drag it to the larger area below (timeline or project) and voila, the clip player will be activated (central area above), you will see the file on the line down, etc. It would look like this:
When we have added the clip it is a matter of just looking for the point, minute and second in which we want to make the cut and place the vertical line there, then we right click + cut and we will divide the video file like this:
To delete the unwanted part we click on it and press [Delete] on our keyboard. If what we want is to delete only a fragment of the video, then we will need to make two cuts, so that we have three fragments of the video, a first that corresponds to the first part of the clip, a second and smaller one that is the one that we will eliminate, and a final piece which is the normal continuation of the video. We select the one we want to delete and delete it, then join (using the mouse) both fragments. Here I show you a screenshot of what the three fragments look like after making two cuts:
By the way, if you want to change the audio and put a song or something like that, first we must silence or mute the video that we add, for this we click on the first video symbol that appears to the left of the video, an icon of a lock appears and to its right two icons of video, the Mute is the first of the latter two. Then we simply add the file from audio desired using the + button with which we add the video and then insert the sound file where it says Audio 1, here is a screenshot:
Obviously, we always recommend not to use copyrighted files and so on ... say no to copyright infringement 😉. Anyway and this is to have a better finished and more professional producer if they need it, they can help themselves in some mastering studio or improve the quality of the audio file, anyway always look for files to 256kbps.
Finally processing and extracting the video
To finish with the edition, we must now extract the video in the format we want, webm, avi, mp4, etc. To do this, click on the button Process o render which is indicated by the red circle.
A window will be shown asking us where we will put the video and the format (as well as other more advanced options that I personally rarely change). When from the left list we select the output format (I use webm) and we have established the folder where the video will finally be, we click on the option Render File, here is a screenshot:
Well nothing more to add. This is basically how to cut videos with Kdenlive and a little more, how to change the audio 😉
I hope it has been helpful to you, here I did not use filters or effects or anything, when I learn a little more public about this, even if someone wants, they are welcome to publish their experiences and tips about it.
