[Alt text: GIF from the music video for “Love Shack” by the B-52s. The video depicts people dancing in a convertible, multiple people in suits and dresses dancing (visible from the waist down), martinis, a duck shaking its tail, and two men playing saxophones. The subtitles read:

The Crowdstrike is a kernel-space app that

has no testing process

Crowdstrike! Baby Crowdstrike!

GIF is really terrible as a video format. You can upload actual video with sound on Lemmy (most instances use a 20MB, 900-frame limit, also server-side ffmpeg often times out) or Pixelfed (15MB, unknown frame limit).

Yes, I know you didn't bother to use an AI or commission an artist to sing the new lyrics but you could mux in an instrumental version (or heck, even just leave the original) for me and others who may remember the melody from the radio but don't associate it with the music video.

True as that may be, I know how to add subtitles to a GIF from YouTube in 10 minutes or less. I don’t know how to do that to a video.

GIF from YouTube

YouTube doesn't provide GIFs. It provides videos. Conversion to GIF is an unnecessary step. Use yt-dlp, Aegisub and ffmpeg for a FOSS way of downloading a video, trimming it and burning subtitles into it.

The correct way to get someone to move to FOSS is to show them how to do it, not tell them it exists. OP already said they can do the YouTube -> captioned gif in 10min so you need to provide a simple tutorial that identifies the tools to use, how to set them up, and how to create a workflow to achieve the goal of some format with captions in under 10min.

Notice how I explained what was wrong and how to do it? That’s what’s missing from most “you need to use FOSS” posts, including yours.

I thought the average !programminghumor@lemmy.world user is already FOSSpilled. Of course you don't have to use the FOSS tools but they are convenient enough to be able to make this in 10 minutes.

Anyway, the relevant commands are

yt-dlp -f "bv*[height<=480]+ba" --no-mtime --convert-subs srt --write-sub https://www.youtube.com/watch?v=9SOryJvTAGs
# aegisub needs srt; we don't need above 480p

aegisub "The B-52's - Love Shack (Official Music Video) [9SOryJvTAGs].en.srt"
# now go rewrite appropriate lines in gui, apply style and save as "LoveShack.ass"

ffmpeg -i "The B-52's - Love Shack (Official Music Video) [9SOryJvTAGs].mp4" -filter_complex "[0:v]subtitles=LoveShack.ass[s];[s]crop=w=640[f]" -map [f] -map 0:a -ss 49 -t 21 -acodec aac -vcodec libx265 -crf 20 crowdstrike.mp4
# crf 20 for generously high quality because file size is small anyway

# or for Lemmy upload (no sound, WebM to prevent encoding...
# ...and subsequent ffmpeg timeout errors; my instance limits uploads to 10 MiB)
ffmpeg -i "The B-52's - Love Shack (Official Music Video) [9SOryJvTAGs].mp4" -filter_complex "[0:v]subtitles=LoveShack.ass[s];[s]crop=w=ih/3*4[f]" -map [f] -ss 49.5 -t 21 -vcodec vp9 crowdstrike.webm
# note that Lemmy instances limit videos to 900 frames (usually 30 s) by default

I didn't bother recreating your subtitle and cut timing but I did crop the video to 4:3. The frame rate is doubled and so is the apparent resolution, while the file size is 6x smaller; the Lemmy version is also about 6x smaller but I went for low-bitrate 720p:
