As you probably know already, you can upload any video to coub as long as it’s no longer than ten minutes and no larger than 200 megabytes. But, again, as you probably know, a lot of the best coubs come from films that are more than an hour long. Of course you can just stick to making coubs from youtube or vimeo clips, but your channel will lack the range that gives the more popular channels their edge.
If you’re wondering how to go about making your own custom clips, don’t worry, it’s not difficult at all.
All you need to do is open the film you want to take a clip from in VLC Media Player, and hit the record button at the start of the section you’d like to record (circled in the picture below).
Just hit the record button again to stop recording. The recorded file usually ends up in your videos folder.
Of course there are more advanced forms of trimming that this doesn’t cover. For example, what if you want to remove a section from the middle of the clip you want to upload? Or maybe you want to join two clips from different movies, like this:
A great tool for accomplishing both of these things is Avidemux. Avidemux has become a favourite tool for accomplishing the glitch effect known as datamoshing, but it can be used for much simpler things like converting, splitting and joining videos, as well as applying some basic filters (adjusting colours and brightness for example). There’s a very useful wiki on how to do these things here.
As you’ve probably guessed, the possibilities here are endless. Whether you want to achieve similar effects to those of old innovators of montage like Sergei Eisenstein, or just want to create a simple but compelling juxtaposition, you have everything you need in avidemux.
