Windows 10: quality of videos reduces

so im not sure why but whenever i save videos on my computer with high quality it reduces and this started happening a little while after i got this new computer i got it last year at the beginning of the year and the quality problems started during august. the videos i save are usually ones i shared from my phone where the quality is normal and good but once i download them and open them up the quality reduces dramatically

:)

 

Good way to reduce video size without compromising quality?

My camcorder records videos at 1080p however a short 4 minute video is a whopping 550MB.

What would you suggest to compress or otherwise reduce the size of the file without reducing the quality?

The format is MTS.

 

Windows 10 Photos video project export quality issue

In Windows 10 I created a video project slideshow with the photos app. I'd like to export this video for a Facebook ad. However, the photos app only gives me 3 options to export and all three significantly reduce the quality of the video versus when I
just view it in the app. Any suggestions how to export and maintain quality?

 

Trim (maybe others edit actions) video reduce quality

I try to trim a simple video i recorded by Nvidia Share with Photos App, the orginal quality is 1080p 60fps, but the trimmed video has only 30fps, and the bitrate is greatly reduced. First i just simple open it with Photos and click the trim video, the output
is only 30fps. Then i try to create a new video project in Photos app and add it to new project to trim it then export, the app show the option output is only the resolution quality, i choose 1080p but the output is still the same ( 30fps , worse bitrate).

What should i do to keep the current quality of the trim video ? Does the Photos have that features ? , if not i recommend adding it in the next update, like the old Movie Maker i used to use which have different qualities output including keeping the current
quality

Also why cant i find the Photos category ?
