It 's graphical user interface looks pretty similar to VirtualDub and most features autosplit known from VirtualDub are available too. : Avidemux natively supports a great number of long video sequencesfile types, such as AVI, MPEG, VOB, TS, MP4, ASF, OGM,MKV and FLV. At the same time Avidemux natively supports saving the data as raw framesa wide range of Video/Audio formats, AVI type including MPEG-1, AVI type MPEG-2,Quicktime 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!

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 It is also outdated (last release in 2014) and doesn't install properly on newer Ubuntu.

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.

scan IEEE1394 (firewire=== Transcoding ===http:/i/programmer-art.link) busgscanbus is a little bus scanning, testing and topology visualizingtool for the Linux IEEE1394 subsystem, with some AVorg/projects/C support,especially for controlling Camcorders and VCRs. It is intended as adebugging tool for IEEE1394 development, but can also be used tosimply check your IEEE1394 setup on Linux.arista-transcoder

high level programming interface for IEEE1394 digital cameralibdc1394 is If you only want a library that is intended to provide a high levelprogramming interface for application developers who wish 5-minute clip, the first thing to controldo would probablyIEEE 1394 based cameras that conform be to throw away the 1394-based Digital Cameraother 55 minutes of video. That should make allSpecification (found at httpyour files load much faster. ://www.1394ta.org/).

This package contains shared librariesYou 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.

library for direct access to IEEE 1394 bus (aka FireWire)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 outfilelibraw1394 is the only supported interface to the kernel side raw1394</source>of Note that the Linux IEEE"-1394 subsystem, which provides direct access itsoffset" option must be specified to themake sure thatconnected 1394 buses to user space. Through libraw1394A/raw1394V timestamps synchronize,applications can directly send to and receive from other nodes withoutthat its value must be the negative ofrequiring a kernel driver for the protocol in question"-ss" argument.

It allows you toorder of command-lineremote control camcorders options and similar devices connected to your computervia an IEEE1394 (aka Firewire) linkarguments 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 package includes 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 libraries needed to SAME volume as the audio in infile. When capturing video in the US, you may also run executables usinginto problems withvideo interlacing. Fortunately, mencoder has deinterlacing videolibavc1394filters, for example "-vf pp=lb".  == See Also ==[[Video Editing/My Story]] [[Category:Video]][[Category:Multimedia]][[Category:Howto]][[Category:Applications]]
