Open Source Cinema
Open Source Cinema is an excellent site I found out about from the equally impressive, Shelly Terrell. This is site for editing/remixing videos. It reminded me a bit of a cross between Remix America and iMovie HD. For example, once a user uploads their video/audio/photos, they can simply remix it via drag/drop, just like in iMovie HD.
However, the one issue I had was how slow it was. This is probably due to the large file sizes of video/audio and probably a bandwidth issue on my end. That being said this was a very user friendly site and I think great way to share/collaborate on videos w/ others.
I don't think any filtering is going on, so keep that in mind if using w/ students.
Your mashup is so cool! I love that you play with these tools! When I tried it took forever that I just lost patience. I'm going back though to join one of the several fantastic projects!
Web casting, or broadcasting over the internet, is a media file (audio-video mostly) distributed over the internet using streaming media technology. Streaming implies media played as a continuous stream and received real time by the browser (end user). Streaming technology enables a single content source to be distributed to many simultaneous viewers. Streaming video bandwidth is typically calculated in gigabytes of data transferred. It is important to estimate how many viewers you can reach, for example in a live webcast, given your bandwidth constraints or conversely, if you are expecting a certain audience size, what bandwidth resources you need to deploy.
To estimate how many viewers you can reach during a webcast, consider some parlance: One viewer: 1 click of a video player button at one location logged on One viewer hour: 1 viewer connected for 1 hour 100 viewer hours: 100 viewers connected for 1 hour…
Typically webcasts will be offered at different bit rates or quality levels corresponding to different user’s internet connection speeds. Bit rate implies the rate at which bits (basic data units) are transferred. It denotes how much data is transmitted in a given amount of time. (bps / Kbps / Mbps…). Quality improves as more bits are used for each second of the playback. Video of 3000 Kbps will look better than one of say 1000Kbps. This is just like quality of a image is represented in resolution, for video (or audio) it is measured by the bit rate.
