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?
- Avidemux (From PPA) - http://avidemux.sourceforge.net/
- OpenShot (From PPA) - https://launchpad.net/openshot/ http://www.openshot.org/ppa/
- Pitivi (From PPA) - http://www.pitivi.org/?go=download
I was going to mention commands like ffmpeg or avconv (The new one) which can OBVIOUSLY split files into groups. For example:
ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.avi ffmpeg -i input.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.avi ffmpeg -i input.avi -vcodec copy -acodec copy -ss 01:00:00 -t 00:30:00 output3.avi
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 -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
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/
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.
Please refer to ffmpeg documentation for more informations
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:
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
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.
Just set the video and audio encoding to Copy and choose the container format you want, within reason.
sudo apt-get install avidemux
For cutting, merging, scaling etc one can use … Blender (yes, this 3D editor, but it has also video editing part). You need workout some 20-min tutorial to survive the interface, but then it appears to be unexpectedly pleasant to use.
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
There is also WinFF that is avconv graphic interface. It works great. I installed it from Ubuntu Software Center.
I use Kdenlive, but I wouldn't be surprised if you could even slice video this way in PiTiVi:
- Create a new project with your full lecture.
- Set your start and end points for the first "manageable chunk" in the clip monitor.
- Drag from the video in the clip monitor down to your timeline. It will be just the chunk you chose.
- Set new start and end points in the clip monitor and repeat as needed.
In PiTiVi 0.13.5 (Ubuntu 10.10) I was able to simply select a clip and go to Timeline > Split (or just press "S").
For quickly cutting I have used MythTV. I recorded some show, let it automatically search for the commercial breaks and fine-tuned the found markers. After this I started the Myth archiving function and burned all to DVD, without the commercials.
I have to admit, it worked gread from about 2006 or such. Somewhere in 2008 or 2009 some update ruined it all, my markers where somehow shifted.
Right now, I'm in the progress of re-installing this myth stuff, just to see if I can get the trimmer/editor and archiver working.
vidcutter is a very useful tool for cutting, trimming and merging videos in ubuntu:
sudo add-apt-repository ppa:ozmartian/apps sudo apt update sudo apt install vidcutter
works in ubuntu 17.10
Yesterday I just found that I can do it online, With a youtube account:) If you are in a hurry, and do not have enough time to try which ubuntu software works for you, then do it online.
Go to youtube account, upload your video, then select Video Manager, there is a Enhancement option, at the bottom right corner there lies Trim option
If you want a GUI application you can use dmMediaConverter, a ffmpeg frontend, which has a split function, without reencoding, fast. Just add the split points and press Run. Also, it can do a lot of other stuff. http://dmsimpleapps.blogspot.ro/2014/04/dmmediaconverter.html
Pitivi too complex? Well... I suggest you learn how to use the mouse then lol
Anyway, I always use Kdenlive. Just import the video, drag it onto the timeline, click on the spot where you want to split it, right-click it, and choose cut. Then remove the part you don't need.
I've struggled with this same issue, having a large video file that I want to cut and save as separate scenes. After trying to do this in the usual suspects all listed by others here I ended up using Kino.
You will have to import the file as Kino needs it in dv format (whatever that is) and you can then specify start and end point for each clip on the Edit tab, then export each clip individually on the Export tab. Works great and is fast, the slowest part is the initial import of the video file. You can even add effects like titles to each clip.
I found that it is hard to find the exact spot to cut the scene in Kino and when I play the vid in the built in player there is no sound (there is when exported) and it plays too fast so I play the video in avidemux, find the time or frame number where I want to cut it, then use this info in Kino.
I do find it crashes a fair bit (I use Ubuntu 15.04 Kino v1.3.4) but it will recover where you were upon restart.
Update on the Kino webpage:
Kino is a dead project
( 05.08.2013 14:15 )
Kino has not been actively maintained since 2009. We encourage you to try other Linux video editors such as Shotcut, Kdenlive, Flowblade, OpenShot, PiTiVi, LiVES, and LightWorks.
