(Note: Always use two-pass encoding for gameplay footage. Single-pass VBR will choke during the boss fights with massive sprite scaling effects.)
My goal was to achieve a transparent encode at a reasonable bitrate. Here is the command I started with:
Have you encountered issues encoding retro game footage? Do you prefer SVT-AV1 or x265 for your emulation archives? Drop a comment below! sonic the hedgehog 3 libvpx
The result? A disaster.
Use FFmpeg to encode the video with libvpx. Here's a sample command: (Note: Always use two-pass encoding for gameplay footage
If you clarify your goal (e.g., "I want to re-encode a Sonic 3 longplay to VP9" or "I found libvpx mentioned in a Sonic 3 disassembly"), I can give a precise, step-by-step answer.
– Could you have meant:
ffmpeg -i source.mp4 \ -c:v libvpx-vp9 \ -b:v 0 -crf 20 \ -pass 1 -an -f null /dev/null && \ ffmpeg -i source.mp4 \ -c:v libvpx-vp9 \ -b:v 0 -crf 20 \ -pass 2 \ -speed 1 \ -row-mt 1 \ -tile-columns 2 \ -lag-in-frames 25 \ -pix_fmt yuv420p \ -c:a libopus -b:a 128k \ output.webm
– A popular PC fan remaster. If you're modding Sonic 3 AIR and want to replace video assets (like the intro), that engine might accept VP9 via libvpx if the devs added it (unlikely; usually uses MP4/h.264). Do you prefer SVT-AV1 or x265 for your emulation archives
In a way, and Sonic the Hedgehog 3 are a perfect pairing. Both represent the pinnacle of their respective eras: one pushing the Motorola 68000 processor to its thermal limits, and the other pushing the limits of efficient, patent-free web streaming.
