are you familiar with ffmpeg? it may be faster to make the subtitles with something like pysubs2, save the subtitles separately and combine them with ffmpeg instead of moviepy

split yoke
#

not fully familar with but i could learn

#

ik moviepy uses ffmpeg so i could just take out the middleman moviepy

#

is there a ffmpeg library?

vivid jacinth
#

there are a few but most/all are just subprocess command builders. I have personally used ffmpeg-python in the past

split yoke
#

do u think i should

#

like can ffmpeg

#

edit videos like moviepy

vivid jacinth
#

yes, probably, with some time and effort
what kinda edits are you thinking about?

split yoke
#

just basic like

#

adding audio

#

and like editing the duration of the clip

#

maybe cropping

vivid jacinth
#

Oh yea, ofc those can be done

split yoke
#

ok

#

alr thank u

vivid jacinth
#

and ffmpeg is one of the most used programs on the planet so there's tons of documentation and examples on how to do all that online

split yoke
#

ok

#

thank u a lot

#

ffmpeg is in C right

#

so should be miles faster

vivid jacinth
#

theres also a ton of assembly and inline asm used in ffmpeg go they're really pulling out every optimization they can

#

they consistently post about new optimizations on social media

split yoke
#

wow alr

#

thanks

#

ima look up the

#

docs

split yoke
#

quick

#

question

#

can

#

ffmpeg

#

create

#

text

vivid jacinth
#

Oop sorry I missed this

#

@split yoke in what way do you mean "create
text"?

#

like bake in subtitles into the video?

#

or add a subtitle file to a video

#

(You can in both scenarios)
