Topic: Record animation to avi


view this post on Zulip Max Köhler (Feb 22 2021 at 12:22):

What is the recommended way to record an .avi from a Plots.jl animation?
Currently I'm recording a gif and convert it with ffmpeg to avi. Is there a built in way?

When I wanted to make a movie, I basically did what you did and saved out a series of .png images, then used ffmpeg to convert them into an .mp4.

Turns out that my latex beamer presentation don't want to include my video. I tried mp4, avi, mov and gif. Why is LaTeX sometimes so annoying

don't you normally just output a pdf from beamer? it never would have occurred to me that it was even possible to include video in it

I suppose you could include a link and then just open it in your browser

It is a pdf, but the video is included, you can do it with the multimedia package which is loaded anyways by Beamer. I don't get why an old avi works but my new created ones fail. This must be related to codecs, but I have no idea about codecs :derp:

even all of my installed media players can play it, doesn't make sense at all

hm... yeah, video in pdf sounds like it's bound to be a nightmare monstrosity to me :laughing:

it is, but imho theres no way to explain it without a video given the time constraints of the presentation :frown:

maybe just include a link to the video in the pdf? I'm pretty sure it's possible to include file system links

ye, using the external media player option works, just opens the default video player. But idk, I can already see zoom failing on this while I share my screen

it just bothers me that the old avi works flawless but the new one doesn't

ok -vcodec libvpx fixed it. Wow, just wasted solid 3h on this

In my limited experience, videos not playing in a pdf is the fault of the pdf viewer, not latex. Videos tend to play fine when seen using Acrobat on Windows.

you are probably right, but there are good reasons to it why linux pdf viewers are so restrictive. Lately, I had to include javascript forms into a pdf and linux pdf viewers block the javascript by default, which is actually good (considering that our university was hacked based on excel macros)

Oh yeah, I agree with you and I don't want evince to start running javascript.
My point was just that it's not Latex's fault :smile:

ye that's correct, sorry if my desperation made the impression that LaTeX is the reason of this issue. Luckily fixed now :tada:
