New Poll: Downloadable File Size Limits

Help us understand what you consider to be acceptable download sizes by answering our quick poll question. It's in the sidebar to the right.

100 to 200 MB seems to be Ok.

The size is related to the length and quality of the video. Quality should not be compromised at all.
It defeats the whole purpose.

Length of the video is determined by the time needed to explain the content. At the same time length can be controlled by focusing each tutorial on a very specific subject and if needed by slicng them into 'part_1', 'part_2' etc.

Thanks for the tutorials. They are very useful.

I suggest you use h.264, much more efficient at comparable quality.

Yeah, I do like the quality of the h.264 files but, the compression times are just too long. I had a 15 min. video that took almost 6 hours to compress!! I just don't have that kind of time. Maybe the settings weren't optimised (I used the default settings).

Great quality, too slow. I'll give it another try after I uprade my computer (whenever that happens).

Would it be possible to write a .py script for tutorial animation? the script would record mouse movements and .blend file changes along with audio (.ogg?). No need to record and compress entire screen images. i imagine you'd have a .py script, an initial .blend file and a .tute file. the .tute would contain the mouse movememnt info, time based changes to the original .blend file, and the compressed audio. the .py script would be installed on the author's/audience's machine to create/interperet the .tute. Seems like tutorial could be made ALOT smaller this way.

To some degree, that is possible. I'm developing something right now that can record/playback mouse movements. Sometimes the playback of the mouse movements gets off a little and the whole thing falls apart (click in the wrong spot, etc.). When it works, it's perfect! I think the problem is with the resolution of the timer used when recording the data. It's in progress...

I also will soon be experimenting with using the Game Engine to simulate the Blender environment. That way a tutorial could be a .blend file (with audio or text balloons similar to a Flash video).

AND, I've read that Ton & Company have plans to create some sort of macro playback capability. This could possibly be used as well.

So, to some degree or another that sort of thing is in the future. The only problem is that you wouldn't be able to follow along with the tutorial unless you opened another instance of Blender. And that may present some performance issues. I think it will be good for very short technique demonstrations but, it won't replace video tutorials.
