What to use to quickly cut Audio/Video

  • 772

If just need to crop Audio/Video from a longer track, what can I use? I tried OpenShot, but I find the export video slow, perhaps its compling all the "layers" into a new movie? Perhaps I just need a simple "crop" tool for audio/video will surfice?

    I was going to mention commands like ffmpeg or avconv (The new one) which can OBVIOUSLY split files into groups. For example:

    FFMPEG

    ffmpeg -ss 00:00:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output1.avi
ffmpeg -ss 00:30:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output2.avi  
ffmpeg -ss 01:00:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output3.avi

    Or

    ffmpeg -ss 0 -t 100 -i source.m4v -vcodec copy -acodec copy part1.m4v
ffmpeg -ss 100 -t 100 -i source.m4v -vcodec copy -acodec copy part2.m4v  
ffmpeg -ss 200 -t 100 -i source.m4v -vcodec copy -acodec copy part3.m4v  
ffmpeg -ss 300 -t 100 -i source.m4v -vcodec copy -acodec copy part4.m4v

    AVCONV

    avconv -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi
avconv -i input.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi  
avconv -i input.avi -vcodec copy -acodec copy -ss 01:00:00 -t 00:30:00 output3.avi

    Or

    avconv -ss 0 -i source.m4v -t 100 -vcodec copy -acodec copy part1.m4v
avconv -ss 100 -i source.m4v -t 100 -vcodec copy -acodec copy part2.m4v
avconv -ss 200 -i source.m4v -t 100 -vcodec copy -acodec copy part3.m4v  
avconv -ss 300 -i source.m4v -t 100 -vcodec copy -acodec copy part4.m4v

    Or do some script like here: http://icephoenix.us/notes-for-myself/auto-splitting-video-file-in-equal-chunks-with-ffmpeg-and-python/

  2. With new version from ubuntu avconv

    avconv -i srcFileName -c:a copy -c:v copy -ss 00:03:40 -t 00:01:12 targetFileName
    • First argument time is from time
    • Second argument is duration (not end time) duration may be either in seconds or in "hh:mm:ss[.xxx]" form.

    To specify end time instead, use the option -to [end time].

    Please refer to ffmpeg documentation for more informations

  3. kdenlive is (in my experience) the easiest software which will allow you to perform that task in a few steps and without problems. Even so, the OpenShot Video Editor project is also useful but it yet needs lots of hard work to get closer to the kdenlive.

    Here are a screenshot of the kdenlive and openshot respectively:

    Good luck!

  4. I like kdenlive for finishing up as well or clipping out small chunks...but if he wants to split a LARGE lecture into smaller pieces he could try: 

    ffmpeg -i input.mpg -ss 00:00:10 -t 00:00:30 out1.mpg -ss 00:00:35 -t 00:00:30 out2.mpg

    discussion of the command is here: http://ubuntuforums.org/showthread.php?t=480343

  5. LosslessCut is focused entirely on clipping/cutting, is simple to use and does not re-encode, meaning saving to disk is pretty much instant.

    enter image description here

    To ensure audio remains synced with image, use the keyframe cut option.

  6. OpenShot Video Editor looks promising. Have you checked it?. Checkout the features: http://www.openshot.org/features/

    The official installation method is via AppImage available at https://www.openshot.org/download/

    To install it just open a terminal and run the following commands:

    sudo add-apt-repository ppa:jonoomph/openshot-edge
sudo apt-get update
sudo apt-get install openshot openshot-doc

    Just give a try. alt text

  7. My preference for easy video clipping has always been avidemux. Avudemux logo

    Just set the video and audio encoding to Copy and choose the container format you want, within reason.

    Installation:

    entry at apps.ubuntu.com Install avidemux

    sudo apt-get install avidemux

  8. I'm using ffmpeg CLI interface for that. It's very easy and fast:

    • to cut video:

      ffmpeg -i InputFile -vcodec copy -acodec copy -ss 00:00:00 -t 00:01:32 OutPutFile

    • to cut audio:

      ffmpeg -i InputFile  -vn -acodec copy -ss 00:00:00 -t 00:01:32 OutPutFile

    In both of these -ss is the start point, while -t is the duration of the piece.

    You can calculate duration e.g. using LibreOffice Calc or python's dateutil package, or you can use the -to option which accepts the end time directly.

  9. Try Avidemux Install avidemux

    sudo apt-get install avidemux

    or LiVES Install lives

    sudo apt-get install lives

  10. There is also WinFF that is avconv graphic interface. It works great. I installed it from Ubuntu Software Center.
