available from repo or as a "flatpak" from pitivi.org
if the install fails with "Error resolving 'sdk.gnome.org': Name or service not known", try to backup the file /etc/resolv.conf and then edit that file so that "nameserver" equals 8.8.8.8
to enable mp4 decoding/encoding, you need some gstreamer codecs that are not dependencies..
If you're not too concerned about getting the latest codecs, you can use this install line - and if you run Debian testing then kdenlive should be quite up to date.
Note: since Debian 8 (Jessie), kdenlive depends on libav-tools - no longer ffmpeg.
For the latest release, see my kdenlive page for info on installing the Appimage or from source.
VLMC
from videolan.org (but it looks way difficult to install as vlc is needed first from git source with masses of libs that don't want to install!!)

Blender
a 3D animation tool that ships with a built-in video sequencer, and with professional looks and features...
available in the Debian repo or downloaded from blender.org/..
one of its major flaws (presently) is it can't render utilising full CPU power, it renders single-thread, split between cpu cores.
See my Blender page for my tips and links to tutorials

Cinelerra GG
A video editor for Linux that is perhaps without rival. The maintained community version is GG.
Cinelerra is no longer maintained for the debian repo, but it is available from the elive repo as a .deb archive.
However, the recommended version to run is the AppImage. The deb version actually crashed with me during renders. (2022)
The AppImage is easy to run, especialy if you rename it to "Cinelerra.AppImage" and make an OB menu entry.
Make it executable first, then launch it with ./Cinelerra.AppImage
Bashburn is straight forward, it uses cdparanoia to rip wav files, converts ogg or mp3 (although adding track info might be tedious). Abcde is much simpler to use (just hit the command `abcde` after you've made a conf file for the type of rip you want to do - see this guide).
GUI ripping: there's K3b, which is big and clumsy, sound juicer (need gvfs-backends) or asunder, which rip and convert on the fly, without first making error-reduced wav files.
Others: rubyripper, ripperx, and grip which you have to build from source (download sourceforge.net)
lame is needed for mp3 encoding.
for movie DVD
with the deb-multimedia repo, you can..
otherwise you need to look for packages elsewhere.
k9copy and dvdrip are both graphical, and you can select which title to rip (but again, there's KDE libraries to install).
dvdbackup is command-line, and it rips the DVD to hdd in its entirety.
With libdvdcss2 installed you can play and possibly rip a DVD encrypted with CSS (Content Scramble System), e.g. it enables Handbrake to rip encrypted dvd titles to mp4, but there is still other encrypion it can't deal with.
To rip with dvdbackup, cd to the dir to store the dvd and run dvdbackup -i /dev/dvd -M -o movie
furiusisomount and acetoneiso are two other useful apps.
