How to create videos with small file size but large resolution ?
13 février 2017, par Gregory MagarshakIs there a programmatic way to create videos that capture, essentially, a powerpoint presentation, that would be not much larger than the audio + screenshots of the powerpoint itself ?
I want to make software that produces videos with the full resolution of a powerpoint on a large screen, and with a person speaking over it and wvwn doodling. Kind of like "bcontext" software. And then I want to export videos for youtube and other places to be hosted. But I want them to be SMALL. So they can be downloaded by people with slow connections eg in India.
What factors can affect video size and how can i take advantage of the relative "stillness" of most pixels at most times to make the compression preserve the full sharpness and yet take advantage of the lack of visual changes ? What software do you recommend ?

Writing animation using ffmpeg fails only with large dataset
13 mars 2017, par TomChoI am trying to save an animation as an
mp4
using matplotlib’sanimation
package. It goes well if the dataset isn’t too large, but if I increase the number of plots/frames in the animation then it fails with an error as iffmpeg
wasn’t installed :/usr/lib64/python3.4/site-packages/matplotlib/animation.py:784: UserWarning: MovieWriter ffmpeg unavailable
warnings.warn("MovieWriter %s unavailable" % writer)
Traceback (most recent call last):
File "/usr/lib64/python3.4/site-packages/matplotlib/animation.py", line 787, in save
writer = writers[writers.list()[0]](fps, codec, bitrate,
IndexError: list index out of rangeI have no idea what’s causing this, since I have
fmpeg
and it works with less frames. I don’t get why it should depend on the size of what you’re trying to create.I’m using python 3.4, matplotlib version 1.5.3 and ffmpeg version
