This week I have been debugging everything and I final (Thanks to my mentor Edward Hervey) got effects working!

So better show you how it works for now. It is still quite buggy, and not really ergonomic, but it is the beginning!

Here is the video (of course edited in Pitivi and using effects). The original host (people.collabora.co.uk) is gone, so the video is no longer available:

You need a modern browser to see this video (chromium, firefox, epiphnay, midori…)

You can grab the code here if you want to give it a try even if it’s not ready for production…
So next week I am going to clean up the code and of course fix the bugs I find. If I have time, I will start working on the UI part.

[Edit] I tried the only website I found that permits to upload ogv files in order to use it with the video tag, but it seems no to work well. So you can find the video here and in better quality here
