One of my friend showed me that the shadow of the small moon is jerky-jumping kinda in the Youtube video.
I thought it was because of the time change that blended the frames a bit and-or the compression Youtube uses.
The original i uploaded was 52 mb, the compressed Youtube file is 10 MB.
But when i played the compressed Youtube file i downloaded from Youtube
on my computer there was not such a big jerkiness of the small moving shadow.
looks like it is related to the way it plays from Youtube only.
You can see the difference by downloading the file or watching it on Vimeo here:
https://vimeo.com/180710509Vimeo is better from a quality aspect mostly anyway as it looks.
I saw stuttering with Youtube in the past but that was related to other problems mostly on the hardware-software side of the users.
But this is directly related to Youtube as it looks.
Not sure if everyone does have the same problem with Youtube but just be aware it might not be related to Sony Vegas, Hitfilm etc. for example if you see such a problem.
