    Quick video editing app?

    Should it take a couple of hours and use virtually all my resources just to edit a 2 hour video into a half hour clip ? I appreciate video editing does take a lot of processing power, but I would have thought just extracting a clip from a video would be relatively simple as nothing extra has to be rendered, just 75% of the video not rendered, so I would have thought it would effectively copy and paste the section of the video I wanted and take a lot longer.

    Am I doing something wrong ? Is there an app that does it quicker ?

    edit - sorry, forgot to put in a title, can a mod please edit ?

    Ffmpeg is your friend,,and will only take a few minutes to cut a part out of your video....
    Code:
    ffmpeg -ss 00:00:12.00 -i input.foo -acodec copy -vcodec copy -t 120 output.foo
    I open a terminal in the folder the video is in....Then i use this ffmpeg code to cut and copy part of the video....
    The 12 is how many seconds in to start grabbing the video....The 120 is how many seconds in to stop grabbing video....
    Cheers....

    Re: Should

    Ok, thanks. you mean that I modify the code depending on where I want it to start and where I want it to stop ?

    Looks like it also copies the exact format the original video is in as well from the "acodec copy" and "vcodec copy" bits, thats great as all the apps I ve tried give you loads of options, but none for keeping things the same as in the orignal file

    Re: Should

    Yes....
    You tell it how far into the video to start....And how far into the video to stop....(hours,,minutes,,and seconds in to start)
    Code:
    00:00:12.00
    (how many seconds in to stop)
    Code:
    -t 120
    I usually open the video in vlc and watch the timer to see how many seconds into the video to start grabbing....

    You also have to change to your video name your grabbing from....
    Code:
    input.foo
    And to the name you want the video saved as....
    Code:
    output.foo
    Remember to open terminal in the folder the video is in....
    This will simply copy the section of video you want ....

    Re: Should

    Great, thanks, I ll give it a go !

    Cant use VLC cos it stopped working ages ago - now if I click on "open with VLC" nothing happens, I ve tried uninstalling and re-installing it but still the same, so I ll have to use buggy old UMplayer or buggy old SMplayer !

    Then you perhaps didn't use AviDemux. It offers the option to simply "Copy" both audio and video streams, no transcoding or demuxing/remuxing is done. I use the GTK+ version and works great here.

    The same thing can also be done with MKVToolnix (MKVmerge GUI > Global > Enable Splitting), but it doesn't offer a video play/preview, needs the timings to be manually typed (in correct format, for example, 01:24 is correct, 1:24 is not) and the output can only be .mkv (input maybe anything). MKV is just a container, so changing the extension (if the input is other than mkv) doesn't mean it'll be transcoded. It is simply packed into the mkv 'container'.
