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

if you use the block 60FPS option youtube will force lower resolutions now as they are no longer converting 1080p 60FPS uploads to 30FPS H264 as they move on with AV1 and WEBM... the block 60FPS mode will drop the resolutions as there is no 30 FPS conversion made above 720p any more if the file is uploaded at 60FPS... H264 4K and 1080P 60 frame rate conversions are not being done on youtubes end any more. turn off block 60FPS and youll get 1080 uploads that were created at 60FPS...

I like this extension a lot. Unfortunately it prevents you from selecting any quality above 1080p. This is fine for my low end hardware but not so good for my other devices. Since chrome extensions are synchronised across devices if you are logged in to the browser I always need to enable/disable the extension depending on the device I'm currently using. It would be better if it doesn't block the higher qualities even if it doesn't work for them... Maybe you could just display a little "h" icon next to the supported qualities instead of blocking the unsupported ones?

I liked the extension but when I install it it blocks all Qualities above 1080 for me so it's essentially useless for me, BUT! I will for sure recommend this for low end hardware as it can be the difference between an old laptop playing 720p or 480p, and for videos that have text 480 makes it unreadable in most cases.

Works perfectly on my old Chromebook with a MediaTek MT8173c processor. 1080p 60fps YouTube playback is now possible.
