ValueError: I/O operation on closed file

There is no mention of it in documentation. I will add an exception before trying to convert.

Thanks for the report ! Apparently there were a few broken things. It's fixed now, just update MoviePy and tell me if it works.
Remarks:

• you don't neep loop=1, it's the default.
• preserve_luminosity doesn't do anything in this case.
• You may want to decrease the fps in write_gif() to have a lighter GIF.

So did it work ?

[mekza]

Yes it did. Sorry for my late reply.

[Zulko]

No probs. Cheers.
