Web based image, audio and video editing has been making quiet but significant progress over the years. Web based editing means every day punters like you and I can edit directly on the website where we store our media - rather than having to carry around (or even own) a computer, or worry about running software on a computer. With nothing but a portable recorder like a phone, we are free to wonder the streets uploading pictures as we go, and then jumping into a cafe or onto a friends computer to edit the media straight through a standard web browser with broadband internet connection.
For example, I upload photos to Flickr and video to Youtube directly from my phone. I just snap a shot, or take a few seconds of video, and send the media up by a special email address that both Flickr and Youtube provide. A while back Flickr quietly added web based image editing for touch ups, basic editing or even for getting post productive. Its as simple as clicking the "edit" button above your image on Flickr and then start adjusting brightness and contrast, adding colour and text, cropping and rotating.. I've been thinking to use it to create titles to add to my videos when I get around to editing them web side as well!
Speaking of which, Kaltura - now there's a promising bit of web based video editing software. Not only does it offer reasonably stable editing, it enables collaboration as well! I primarily use Kaltura as it is on the Wikieducator web site, although there are a range of other websites using Kaltura to offer web based and collaborative video editing.
When you are looking at a Kaltura player/editor (very easy to add one to a page on Wikieducator btw), you have two options: "add to this video", and "edit this video". Pretty self explanatory hey. When you click "add to this video", you have the options to add video from Youtube, photos from Flickr, and audio from CCMixter, among others. This is pretty handy seeing as I already load footage via the phone to Youtube and Flickr - not to mention the possibility of creating fancy titles and image effects on Flickr as well.. Its nice to be able to continue loading and storing on other sites, and then feed them into Kaltura when needed. (There's quite a lot of possibility in this approach to multi media, not to mention just a little bit more security in backup). When the "clips" are all feed over to your Kaltura editor/player, you're ready to get to work editing on its basic (but not too basic) editor. Other's can come in on your edits too, making Kaltura a web based video editor with collaborative potential as well.. I don't play too well with others, so I can't say much about that - always open to the chance to co-edit though :)
There's one downside to Kaltura sadly. We're still waiting for the obvious feature that enables downloading a finished video for playing offline. Unfortunately this is not offered yet so we're left with online viewing only.
