Camtasia comes to mind-but not sure if open source...might be worth a look though.
Have you tried Youtube's video editor? https://www.youtube.com/editor
Video editors installed on your computer generally require a powerful 64-bit computer with at least 4GB memory (but more is recommended). And if you try to do a lot of video editing on a laptop, you'll eventually "burn out" the graphics card, which usually costs more to replace than a new laptop, and/or the DDR memory cards (cheap and easy to replace yourself).
If you don't have sufficient hardware, an online option if definitely a good idea.
I hope this helps!
All video editors should upload online. Do you mean edit as on download an editing software to your desktop? Then you can upload to anywhere you want to. That's what I would personally prefer.Theres a few links below that are open source.
If you really do mean editing online, a google search is flooded with them. To me they simply appear to be wannabe family social networks like facebook, which is not to my taste. I'd rather direct my contacts and my videos to my own site, and not somebody elses.
thanks for your suggestions. I think my description was not clear enough.
The videos are from university lessons. They arre using two camera soften and they have to edit this raw material to an attractive new video. This means some scenes have to cut out, To make it more interesting it should move from one camera perspective to they other and sometimes it will be required to show the perspective 1 (lecturer) as a small area into the main perspective (presentation slide view) - picture in picture mode.
The editing process is team work. The team members are working from different location. That means that the raw material has to be upoaded to a web portal and the team members get access to it for working on the same project.
The raw material and the final result is not for public. Only students will get access to the video in a Moodle plattform.
Hope you can understand better what is required.
If I understood correctly, you want something like GoogleDrive--which allows people to work simultaneously in a document--but for video. I don't think there is something like this. Video is definitely more complex that regular documents (be them, word, excel, etc.) and editing requires more resources (e.g. memory, processor speed).
As I see it, the team should use a cloud service like dropbox, sugarsync or related ones, so the video can be shared to everyone, eventhough only a group could work on it at a time. Then, they could use skype or a similar service so while one group is actually editing, the screen is shared to the whole team and so everyone can suggest about the edits to be done.
If two groups were to open and try to edit a particular video at the same time, the cloud service would create two different physical versions, just as it happens with regular documents. GoogleDrive is a similar but different concept, and that's why GD allows simultaneous editing, but not for video, at least not yet.
Not exacly what you need, but it may cover part of your requirement (i.e. just the editing part, not the collaborative one):
When I went to research Video Editor, I found a number of different products called "video editor". Which one are you specifically referring too?
