Write_Gif returns errno 2

[selfcommit]

Calling write_gif

from moviepy.editor import *

clip_file = "./Import-csv.mp4"

clip = (VideoFileClip("./Import-csv.mp4", audio=False).subclip((0,0.0),(0,16.25)))

clip.write_gif("./Import_csv.gif")

returns the following error:

Ugh, I tried manipulating a number of different things, but of course resolved it AFTER posting.

clip.write_gif() needed a valid location to write to.

My apologies.

Cool. A few tips:

• your gif has by default the same fps as the original video. In your case, 30, that's a bit much. just provide fps=15 for instance in write_gif to change that.
• you can use write_gif2() instead of write_gif, it's the same in slightly faster (no temporary files, everything is done in the RAM).
• Keep in mind that GIF generation is much slower than video generation (because ImageMagick tries to compress losslessly) so outputing videofiles is better to preview clips. If you installed moviepy recently and you use the ipython notebook you can preview your clip in the notebook with ipython_display(clip, autoplay=1, loop=1).

Thanks write_gif2 is MUCH better, also saves me having to clear the directory on a failure...

Do you have some sample code on using ipython notebooks? I just grabed ipython but I'm not familiar.

Hi, thanks for the great package !
I'm having the same issue when trying to run moviepy on OSX Mavericks (example1 of "Vector animation with Python").

And being a bit of a newbie in Python (and in coding, really), I'm not sure what @selfcommit means by "clip.write_gif() needed a valid location to write to". A pointer in the right direction would me much welcome !...

Hi @nico7et8 , I don't think it is the same as @selfcommit, in your case MoviePy cannot find the program convert, which certainly means that you didn't install ImageMagick on your computer. Tell me if it works once you have installed ImageMagick.

[nico7et8]

Thanks for such a quick reply !
I have installed ImageMagik but maybe not the right way. I'll check again if I've done everything by the book and see how it works.
Thank you again.

Hi again @Zulko , sorry for the disturbance and thank you for your time.
I've re-installed everything (I'm using Python3.4 on Mavericks) :

• moviepy
• ffmpeg (successfully found by conf.py)
• ImageMagick (convert command works in the terminal, as suggested on the ImageMagick website)
  I've even tried to point IMAGEMAGICK_BINARY to the imageMagik convert file but I get the same error message :

Traceback (most recent call last):
  File "/Users/nicolas/Projects/vectoranim/test01.py", line 15, in <module>

If you have an other minute to spare, any idea or direction would be welcome. Thanks again.

[nico7et8]

Scratch that, it works !

[Zulko]

Yay ! So what made it work ?

[nico7et8]

I'm looking into it...
Yes : It must be a very beginner mistake bit :
I had changed the IMAGEMAGICK_BINARY of conf.py in the wrong folder (moviepy instead of moviepy-à.2.1.8.12.py3.4.egg). Sorry, I'm new to all this.
But thank you for your time. Animation and Image/movie processing is the reason I took up python and your package is exactly what I've been looking for. Thanks for all the work !
