Hi
Nice to get downloaded files that is not GB in size. 🙂
The original downloaded image...DDDA 1920 x 1080 jpg

Exported mp4 image 1920 x 1080 default quality in VLC........

I don't expect the resolution to equal the original image but this is OK as a video..
The other thing to mention is that your zoom seems to have a lot of unnecessary key frames......

This makes it a bit jerky (although it IS very short.🙂
Just use two.. 1) Start over on the right outlining the bit needed and then 2) Full frame. ... at 00:1.53......

Takes no time to set up and is smoother. VP will sort out all the intermediate frames.
