Pitivi get effects, part 4

I didn't blog for almost 2 weeks now because I wanted to have something interesting to say before saying it!

So the last 2 weeks I started an experimental branch to handle effects in the timeline and of course corrected all the bugs I found during this time. Then I rethought this design with nekohayo and got this pretty cool mockup from him:

So as you can expect, I am now implementing that. I already rewrite the effect list and it looks the same as you can see in the mockup. And I am working on making effects being per clip or per track instead of being considered as clips themselves. This should actually be pushed by the end of the week.

So afterward I am going to work on this new middle section for clips properties and effect configurations. I think I will get it working in the next two weeks. I am quite in advanced on the planning I proposed for the postulation but this is a good thing because I am still at university and may have to spend more time for it in the coming weeks.

You still can grab my latest code here and play with it!

Pitivi gets effects, Part 3

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!):


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

Pitivi is getting effects, Part 2

Here is my second report about the implementation of effects in Pitivi. I am going quite well with this project, and I now have almost everything ready to be able to add effects to videos. The dragging of effects to the timeline is almost ready, but I need to work on it a bit more to be able to show you a screen-cast! I hope it can be done next week.

Sorry for this kind of useless post, but I just wanted to tell you I make good progress, and I should be able to show you more soon!

You still can have a look at my git repository

Going to GUADEC

Thanks to the Gnome foundation for sponsoring my travel to attend to this year GUADEC

I am looking forward to be there and finally see the people I am working with!

Pitivi is getting effects, Part 1

Here is the first report about my Google summer of code project. I have been working quite a lot on it for the last 2 weeks! So here is the summary of what have been done so far:

• Code reading, analyze of Pitivi architecture (Thanks to the pitivi wiki)

• Some reading about Gstreamer to understand better the way it works

• Creation of my git branch to start working on effects implementation

• Implementation of the core Pitivi modifications to be able to create effects (With unit tests)

• See how I can implement effect files as described in my Gsoc application, and discussions about it in the Pitivi community. We actually didn't take a fixed decision about this for now.

• Creation of the UI to show the list of effects detected thanks to the gstreamer registry (the list was already retrieved in Pitivi)

• Some talking to know how this UI should be done. I will need to talk more about that to the Pitivi community to take a good decision about how it should look like. For now, it looks like:

I am now working on drag'n droping effects to the timeline.

That is all for now, and I will give you frequent news about how things are going.

I have been accepted for the Google Summer of Code 2010

I haven't blog for a long time since I had other things to do. I really wanted to participate in the Google Summer of code again, and I have actually been accepted in the Gstreamer community! The project I am going to work on is called "Permit pitivi users to add effects to the videos they are editing". The main goal is to permit to add all kind of effect easily in Pitivi and implement the most important ones.

I want to thank everyone who is responsible for the Gsoc, and my participation in it! I also want to thank and say "Hello" to Edward Hervey who is going to mentor me during the project and to the whole Gstreamer and Pitivi community.

Presentation of a programing course of Python (and other Gnome related technologies) I am now teaching

I wanted to talk about a class (Taller en español) of Python I am teaching now in the University of Playa Ancha in Valparaiso (Chile).

First I want to share with you the great tool I found to make presentations which is Inskape with the JessyInk plug-in. It lets you make presentations in SVG format quite easily, and I personally find the result pretty satisfying! I am using it for all my presentations now, and obviously for the ones I am making for this lesson. Here is a good introduction to jessyInk, I also found a good video tutorial to help you starting with this plug-in. I actually didn't know anything about Inkscape before this, but with this video tutorial I learned fast and I am now able to make presentations with those tools.

The video tutorial to start with JessyInk

I also wanted to share with you the content of this class, so I created a git repository on github containing my presentations (in Spanish) and the examples which go with the course.

I didn't find anything similar so I decided to do it myself hoping it can be useful for other Spanish speakers! And you are of course encouraged to improve it, translate it and correct my mistakes.
