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

amigos eu nao queria saber do google chrome so porque ficava travando en vidios 4k mesmo carrego mas agora com esta estensao roda lisinho sen travar nota 10
mi old asus can take full power of nvidia 425M thank you soooo much for this mod
Dell D420 on W7 starter, transformat in "Razbunatorul" pe acest addon.Bravo baieti :)
CPU usage dramatically cut down. Fan noise no longer an issue.
this is very important tool for youtube video, because default youtube video format vp9 eats almost all CPU power during video watching process, especially in 4k videos, but H264ify changes vp9 into mp4, which is making CPU usage about 20-25 % instead of 90-100%: Thank you very much!
Шикарно
e o unico q faz rodar em 1080
Life saver! Perfect for an old quad core
Awesome for my aging laptop... As my laptop screen does not support more than 768p and has an i3 4th gen processor vp9 format had no added benefits and was just making life worse: 1. High CPU usage 2. Video stuttering Now it's awesome...
Very good extension, before that my Skylake-U laptop was overheating on YouTube, now it's fine.
