And I loved it.
I started encoding everything in VP9. Family videos. Screen recordings. A timelapse of my basil plant growing. Each one taught me something new about spatial prediction, entropy coding, the quiet beauty of a well-tuned --end-usage=q. a different man libvpx
No blocks. No smearing. Just the cat, sharp and clean, fur rendered frame by frame, motion vectors whispering like ghosts through the macroblocks. And I loved it
ffmpeg -i cat_jump.mov -c:v libvpx -b:v 1M -crf 10 -qmin 0 -qmax 50 -speed 2 -threads 4 -lag-in-frames 25 -auto-alt-ref 1 output.webm That’s not a command. That’s a personality test . Here’s the thing about libvpx: it’s slow. Not “go make coffee” slow. “Go learn a musical instrument, forget it, then come back” slow. The first time I ran a two-pass encode on a 4-minute clip, I watched the terminal like a fireplace. Percentages crept upward like molasses in winter. Screen recordings
When I see a blurry Netflix stream or a stuttering Zoom call, I don’t get angry. I get curious. What’s the bitrate? Is that adaptive? Did they forget --enable-alt-ref?
You become a different person. Someone who reads encoder changelogs for fun. Someone who dreams of rate-distortion curves. When the encode finished — hours later — I held my breath and played the WebM.
