If you observe the video at 0:04 and after 0:05, you can see that it magically sharpens a certain part of the video as shown here: 

 

I want to know what is happening here? Can you guys help? Why this is weird switch in sharpness happening after 0:04 mark? This video was rendered using Media Encoder (h264, 1440p, tried using 16-25-45 bitrate, but this 'switch' keeps on happening).

Nature of the codec: it became sharp because that's when the displayed frame was an I(ntra)-frame or B-frame. It was blurry due to lower resolution/bitrate from YouTube & the "drawing" images were P(redictive)-frames.It still happens on the 1080p version, but you don't notice it because it's higher resolution & allowed a higher qulaity bitrate.

Looks fine to me. You need to give YT time to complete the encoding.

It was uploaded quite a while ago. If you set it at 480p, you can notice the difference - the blurry part becomes sharp after 0:004 mark.

Hi Jon - Thanks for your very technical answer. This sheds light on what has been vexing me since quite a while.

Is there any way around this? Like, trying to minimize this effect of switching between B-frame and P-frame? I have seen other write-on type videos (for eg minute physics etc), where in this 'switch' doesn't happen that noticeably or doesn't happen at all.

 

While rendering, will using a higher bitrate somehow lessen this effect? Or any other way around?

This is Youtube: you have no control over their encoding.
