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

Makes youtube run a bit better. Couldn't ask for more.
Расширение помогло решить проблему с воспроизведением видео в 60 fps на Chromebook.
Brilliant. From 60% usage on the chrome process, to 3% usage. Now i can play game and have a video running at the same time.
This is amazing! Using my cheapo work laptop I was afraid that I would't be able to watch 60fps videos. But you made it possible to watch 60fps videos on a Celeron processor! Love ya!
I'm running Fedora 24 64-bit, google-chrome-unstable. After doing hours of research trying to get hardware acceleration working on my lenovo 1580 edge 2, a pretty recent and pretty fast laptop, I ended up with chromium's dev team saying they aren't working on it. They will not work on it because they do not think it is necessary.... This extension instantly fixed the lag I was having running 1080p60fps. Thank you for this extension.
This worked great until 1 hour ago when every page with a youtube video will automatically go to the aww snap page. :( I really loved this extension.
Works as intended, great extension. With this finally Chrome doesn't drop frames on YouTube Thank you.
720p youtube videos running smoothly with an AMD C60!
Great extension, videos are a bit smoother with this now that all the demand iss off the CPU but I'm bummed that it doesn't allow 2K/4K playback, I have to go incognito to watch UHD videos on YT.
Good.
