Want to cut a clip out of a video and share with your friends? Try Video Trimmer, a stupid easy way for those working on Linux.

In Linux there are quite a few ways to cut clips or trim videos either in graphical or using command line tools. While video editors are heavy to do the job, FFmpeg is the most efficient choice. And Video Trimmer offers an intuitive user interface for those hate Linux commands.

It’s a free and open-source GTK app based on FFmpeg. By importing video via top-left “Open” button, you can preview the video and write down the start and end timestamps. And the top-left button turns to ‘Trim‘ for cutting the clip out.

It outputs the clip as a new video file. And the process is super fast and does not reduce the video quality, because it just cuts the data steam but never re-code.

The source code of the project is hosted on gitlab. Besides building from the source, you can install it on most Linux via the Flatpak package.

For beginners, you can open terminal from start menu and run following commands one by one in Ubuntu to get the software.

1.) Install the flatpak daemon for running the app via command:

sudo apt install flatpak

2.) Add the flathub repository which hosts the software package by running command:

After that, open it from start menu and enjoy!

The open-source video transcoder HandBrake released new 1.4.0 version with exciting new features.

HandBrake 1.4.0 adds native 10 and 12-bit encoding support. Though it has limitations that some filters (e.g., Detelecine, Chroma Smooth, and more) do not currently support higher than 8-bit. With these filters enabled, you won’t benefit from the new feature.

How to install handbrake 0.10.2 in Ubuntu:

For Ubuntu 14.04, Ubuntu 14.10, and Ubuntu 15.04, the latest release has been made into its official PPA repository.

Below is how to add the repository (to receive future updates) and install handbrake both GUI and command line tool.

1. First open terminal from the Dash/Launcher, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command:

sudo add-apt-repository ppa:stebbins/handbrake-releases

handbrake-ppa

2. After adding the PPA via above command, you can either install handbrake by running below commands one by one:

sudo apt-get update

sudo apt-get install handbrake-gtk handbrake-cli

or use Synaptic Package Manager (available in Software Center) to update and install handbrake:

3. Due to a bug related to the Unity overlay scrollbars, there’s a blank widgets issue which can be fixed by running below command to edit handbrake’s .desktop file:

gksudo gedit /usr/share/applications/ghb.desktop

Install gksu from Software Center if the command doesn’t work. When the file opens, change the value of Exec to env LIBOVERLAY_SCROLLBAR=0 ghb %f so it look likes:

disable-overlay-scrollbars

That’s it. Enjoy!
