hi list! since i like big proposals, i come here with another one :P some time ago someone wrote on the forums about a project, gvfx.blogspot.com, which is actually a python script to embed images and videos in blender animation i had a talk with one of the two guys behind this, and i'd like to discuss this feature with you all
1. how does it work? here's the script: http://gvfx.blogspot.com/2008/01/script-gfvx-firts- version.html with the new coming version of the script (i would contribute to it, it's quite easy), you would have to supply one or two video files, select the frame range for the clip(s) (the duration of the effect/transition), and choose export parameters as well as the effect/transition you want 2. how to implement? here's what i think: we could add a "3d transition" in the transition dialog (and list available effects in their list - the way to detect them should be defined - but i'll focus on transitions now) and list (like in the luma transition) all available 3d transitions (we could have the big "official" .blend file and lots of user contributed small files) blender does take a long time to render, but it's about 5-10 seconds with a 80x60 animation, so we could show a preview (maybe with just A and B images) of that size (only in the dialog, not in the timeline!) those transitions should then be saved as kdenlive special ones; when rendering, we should: 1. warn the user about the long long time it could take 2. render all the timeline with melt alone (there will be rough cuts where 3d transitions are) 3. render the 3d transitions (think about slowmotion clips, or effects... blender needs a plain video) 4. join the clips (with melt, i guess) 3. pros and cons pros: - i can't think of any other way to implement 3d in kdenlive (maybe you can) - it would be easy to contribute custom transitions (i'd start making lots of them!). and effects, of course. you can have a look at some of them on that website (testing them is quite funny) - blender can also apply complex color filters and/or uv distortions (they're working on this), or... titles? cons: - it depends on blender (we already depend on other software like recordmydesktop or dvdauthor, but blender is big...) - it takes a lot of time to render (they're talking about using the game engine to make it faster, but i guess it wouldn't work with every animation) - you have to render the project 2-3 times - the worst one, i think: you're limited to blender video export capabilities. unless we export to png and then join every single image to match the project profile (they say it should be faster then rendering to video), there's only avi and mp4 i think (dan could put light on this maybe) well, that's it, to begin if you are interested, i can write a patch to test it (for the list eyes only) regards -- Alberto Villa <[email protected]> ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Kdenlive-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/kdenlive-devel
