Animation clear_temp=False reuses old frames

[goretkin]

Using MPL version 1.0.1
If I make an animation consisting of 10 frames with the clear_temp=False option and then make an animation with 5 frames in the same folder, then the resulting movie contains the 5 frames from the new animation and the 5 final frames from the old animation.

Here's an example: https://gist.github.com/2989424

Thanks for the report. The save() support on 1.0.x was really half-baked, so I don't think it's worth fixing there necessarily. git master, which will become 1.2 has substantially refactored the writing support to be more robust and support passing more options to the writers.

I've fixed this on master by passing -vframes to ffmpeg and -frames to mencoder in commit ed6a250.
