A huge number of multimedia == Applications ==   There are several fully professional "Non-Linear Video Editing" applications are available in the Free Software world of Linuxfree software realm. See [[wp:Non-linear editing system]]s I've only briefly toyed with them so I can't tell you from personal experience how easy it might be to do a quick project. But Blender, OpenShot and [[wp:Comparison of video editing KDENLiVE are amazing free software]]applications.  

Get familiar with these These are some of the free editing tools.

Lots of tutorials on YouTube (see right for example) ; [http://www.openshot.org/features/ OpenShot]: {{#ev:youtube|https://www.youtube.com/watch?v=_0nEHxtTjk4|300|right|OpenShot 2.0 reaches beta|frame}}: is another Linux only NLVE, and might be more 'beginner friendly' ; [http://ffmpeg.org/ FFmpeg] [[wp:FFmpeg]] : One of, if not ''the'' most useful tool in the land of multimedia is FFMPEG.; [http://www.transcoding.org/cgi-bin/transcode Transcode] [[wp:Transcode_(software)]] : tool is built using the libavcodec library of FFmpeg.; [http://www.avidemux.org/ Avidemux] [[wp:Avidemux]] ([http://www.avidemux.org/admWiki/index.php?title=Main_Page wiki]) : Available in three user interfaces (GTK+, QT4 and cli) for all major operating systems. : Avidemux is a free video editor designed for simple cutting, filtering and encoding tasks. It's graphical user interface looks pretty similar to VirtualDub and most features known from VirtualDub are available too. : Avidemux natively supports a great number of file types, such as AVI, MPEG, VOB, TS, MP4, ASF, OGM, MKV and FLV. At the same time Avidemux natively supports a wide range of Video/Audio formats, including MPEG-1, MPEG-2, MPEG-4 ASP, H.264/AVC, DV, HuffYUV, MP3, AAC, AC-3 and Vorbis. Tasks can be automated using projects, job queue and powerful scripting capabilities. Video-DVD or (S)VCD compliant streams can be created with easy-to-use "Auto" wizards. Multi-threading is supported!

It does this by writing specific "Group of Pictures" (GOP) sections to a new video file.

It's both a NLVE and a compositing application. There is a friendly fork called the Community Version (CV) as compared to the original Heroine Warrior (HW) version. === Video Slideshows ===; [http://ffdiaporama.tuxfamily.org/ ffDiaporama] : for making a slideshow video, and it's not bad. However, it simply refused to render my project with a 'encode error'. It is also outdated (last release in 2014) and doesn't install properly on newer Ubuntu. The project itself is a fork of the even less maintained Diaporama; [http://imagination.sourceforge.net/ Imagination] : is a simple tool. Last released in 2011, there is at least a note in 2017 that contributions are welcome. The results weren't bad either. But, I still like the power of OpenShot.

; [http://www.mplayerhq.hu/design7/info.html MPlayer] [[wp:MPlayer]] : is one of the most essential players in the Free Software world. The project works in tandem with FFmpeg. MPlayer software includes the '''Mencoder''' commandline tool; VLC : vlc is cross-platform and wonderful. It even works on your phone.  === Transcoding ===http://programmer-art.org/projects/arista-transcoder == Mencoder and ffmpeg examples == If you only want a 5-minute clip, the first thing to do would probablybe to throw away the other 55 minutes of video. That should make allyour files load much faster. :) You can extract the part you want with mplayer like this:<source lang="bash">$ mencoder -ovc copy -oac copy infile -ss 00:10:09.5 -endpos 00:05:00 -o outfile</source>"-ovc" means "output video codec", "-oac" means "output audio codec",the "-ss" argument skips ahead to 10 minutes 9.5 seconds into thevideo, and "-endpos" tells mencoder to transcode exactly 5 minutes."copy" is a special codec name that tells mplayer to just streamcopythe audio and video streams to output... essentially cutting out the5-minute segment that you want. This can also be done with ffmpeg:<source lang="bash">$ ffmpeg -acodec copy -vcodec copy -itsoffset -00:10:09.5 -i infile -ss 00:10:09.5 -t 00:05:00 outfile</source>Note that the "-itsoffset" option must be specified to make sure thatA/V timestamps synchronize, and that its value must be the negative ofthe "-ss" argument. Note that, for BOTH mencoder and ffmpeg, the order of command-lineoptions and arguments is not just significant, it's HIGHLY significant. To transcode the video, specify the output codecs as the "vcodec" and"acodec" sub-options to the libavcodec option (-lavcopts):<source lang="bash">$ mencoder -ovc lavc -oac lavc -lavcopts vcodec=mpeg4:acodec=ac3 infile -o outfile</source>Here, "lavc" means to use one of the libavcodec codecs, specified bythe "vcodec" and "acodec" suboptions to the "-lavcopts" option (whichspecifies options for libavcodec). mencoder has about a bazillion^2command line options, sub options, sub sub options, and can get quiteconfusing. ffmpeg can also transcode audio and video streams from onecodec to another. If you want to change the framerate of the video, you can usesomething like this:<source lang="bash">$ mencoder -ofps 25 -oac copy -ovc copy -o outfile infile</source>Note that, whenever you use "copy" as the codec, mplayer will copy thecorresponding stream to the output unmodified. That means it will ignoreany filters set up to modify the copied stream. This is a BIG gotcha. For example:<source lang="bash">$ mencoder -oac copy -ovc copy -af volume=10 -o outfile infile</source>WILL NOT DO what you probably want, because with "-oac copy" the"volume" audio filters (specified with "-af") will be ignored, and theaudio in outfile will be at the SAME volume as the audio in infile. When capturing video in the US, you may also run into problems withvideo interlacing. Fortunately, mencoder has deinterlacing videofilters, for example "-vf pp=lb".
