VLC Media Player has been a popular choice for several years now.
VLC offers you the most comprehensive set of features out there.
Being a free and simple-to-use program, you definitely cannot beat that!
It allows you to synchronize your subtitles, has multiple video and audio features and even plays DVDs!
Doing so is super simple.
In the next window to open, findInput/Codecsabout halfway down the menu on the left side and press it.
Choose your preferred controls from there.
Be sure to clickSavewhen you make any changes.
What makes it awesome is the fact that YouTube itself doesNOTallow you to do this natively.
If you want, you could speed the video up like 1.2 times.
I have been using VLC Video Player for several years now, and absolutely love it.
Have you tried it?
