Overview
Product summary
Review the store description, core capabilities, and common use cases.
Try h264ify if YouTube videos stutter, take up too much CPU, eat battery life, or make your laptop hot.
By default, YouTube streams VP8/VP9 encoded video. However, this can cause problems with less powerful machines because VP8/VP9 is not typically hardware accelerated.
In contrast, H.264 is commonly hardware accelerated by GPUs, which usually means smoother video playback and reduced CPU usage. h264ify makes YouTube stream H.264 videos instead of VP8/VP9 videos.
Note: 4K and 1440p videos will not be available because YouTube no longer encodes those videos in H.264

Excelente me encanta como hace que uno pueda ver youtube en 4k , deberia estar incorporado automatica en chrome por defecto , perfecta extension h264ify. Saludos
me sigue a lo mismo 95% uso de cpu
Finalmente posso rivedere i video a 1080p senza inutili lag dovuti a inutili fps troppo elevati. Funziona!
Chrome stutters terribly even on Kaby Lake decoding 4K VP9 (60-100% CPU), but with this extension, it plays 4K without a hitch (5-15% CPU).
Good but not great, This extension does indeed make youtube videos stream in H264 but in turn causes youtube videos to skip or cut out randomly.
感謝這個軟體，可以看1080P60FPS影片了。
Wow. My CPU usage while viewing youtube went from 30-40% to 5-10% on SurfaceBook. That's GREAT!
Awesome, 360° 4K works fine now, before it was choppy as hell!
2160p doesn't work at all on Youtube with this extension. doesn't appear in list of resolutions despite mp4 file is available.
This is perfect! Thanks!
