Solution to Youtube video buffer loss and restart on fullscreen

Almost every one might have experienced this when watching YouTube videos that when we go from normal to full screen, the buffer is lost and the buffering restarts. This is really annoying. Especially when your internet is slow and you have waited to let it buffer so you can watch the entire video at a time.

I have been experiencing this for some time but never really bother to find the solution. Sometimes it does not happen when I pause the video and then go full screen. But not always. I looked up on the internet and found various different explanations….Some forums have weird suggestions like installing add-ons, scripts etc…
But don’t worry..All you need to do is:

  1. Log on to youtube
  2. Go to ACCOUNT under your user name displayed on the top right corner.
  3. Click PLAYBACK SETUP on the left hand side
  4. Change VIDEO PLAYBACK QUALITY to
    CheckI have a slow connection. Never play higher-quality video.

That’s it. Now enjoy your videos without restart.

On one site it was mentioned  that this happens because when you go full screen YouTube video resolution changes from 320p to 480p. And I found it is the cause. The resolution was 360p and then it changed to 480p on full screen.

NORMAL SCREEN
FULLSCREEN
The screen shot is different but it’s the same video : )

But when I tried on various other videos, it’s not always the case. Some videos play at 480p on normal as well as full screen. Some play at 360p on both. So that I think depends on the resolution of the video available.

So far from the videos I experimented, I realize that if the setting discussed above is not applied, then Youtube switches from 360p to 480p if a high resolution video playback is available; and so during this switch the reset happens.
No matter what the resolution, after doing the change in PLAYBACK SETUP, the butter restart never happened (as far as I tried). So cheers!
