I always find that TikTok downloadable videos have a great size to quality ratio. With dark magic, a friend figured out what #ffmpeg options they use. Here you go:
ffmpeg -i input.mp4 \
-vf "scale=576:1024:flags=lanczos" \
-c:v libx264 -profile:v high -level 3.1 -preset slow \
-b:v 385k -maxrate 420k -bufsize 800k \
-c:a aac -b:a 37k -ac 2 -ar 44100 \
-movflags +faststart \

I did this amazing recording of a tree swaying in the wind and knocking at another tree the other day for my upcoming mini exhibition at Notam. It was recorded by sticking a Geofin in between the roots to get the sound of the wind from the perspective of the tree.
I will resynthesize this as a vibrator motor signal for the exhibition too. Pretty excited!
MTS files are a common container format for high-definition video, often used by HD camcorders, and can be played with various media players like VLC, or converted to other formats like MP4 using Handbrake or FFmpeg. Video editors like Kdenlive, Flowblade and Shortcut also support editing MTS files.
Checking my download of tonight's #Monsterdon and it is REALLY shaky. I found this blog on how to do #video stablization with #ffmpeg. I love the way it shows how to make a side-by-side comparison video. This is 10 seconds of the opening credits. original on the left, stabilized on the right.
#FFmpeg is multi-platform swiss-army knife of libraries and tools, of which only one ffmpeg command.

I'm not an expert user but over the years it has helped me to:
* convert ripped CD flacs to mp3/ogg
* re-encode video for a specific task eg friends' problematic players, and even projection at an art exhibition
* making animated maths visualisations from a sequence of images from python matplotlib eg
ouch... I did go deep to find this one:
Extracting audio with ffmpeg -ss is off by 133 ms ! this is 4 frames in 30FPS. Quite annoying when you're using the audio track for syncing purpose!

One of the car stereos I use has the strangest bug: Any #m4a file over 4:30 (4 minutes, 30 seconds) will skip for a second at 4:30, play for another 30 seconds or so, then just go onto the next track. Music from #iTunes or things from YouTube make no difference. Simply copying from .m4a to .aac with #ffmpeg avoids this issue. #digipres #aac

When you realize most of the magic that TikTok does is just ffmpeg behind the scenes
What an incredibly powerful piece of software!
MPV 0.40.0 released. This release requires FFmpeg 6.1 or newer and libplacebo 6.338.2 or newer.
If your system uses Wayland instead of Xorg, you may sometimes encounter a black screen issue when using x11grab from FFmpeg because x11grab works best with Xorg. Switching to a Xorg session should fix the problem.

Yes, FFmpeg is far from just being some plain copy or convert command. It is packed with powerful features and, in fact, sits in the background behind many fancy GUI applications, with FFmpeg during the work in the background.

Shit, I just realized there is something from #Twitter I really do miss, and that is the #FFmpeg account. Someone has to know somebody over there. Though, it would be kind of funny to act like #Microsoft and file a "High Priority" bug report on a community run, open source, project
btw here are the options you need if you want to use ffmpeg to only mux (to change metadata or stream order or w/e):
-map_metadata 0 -map_chapters 0 -map 0 -c:v copy -c:a copy -c:s copy
Maybe I should just make turning GifCities gifs into Minesweeper maps my "thing". Would be a lot less expensive than eurorack that's for sure. #creativecoding #imagemagick #ffmpeg
