How to properly import trim video and export finished video?

Question

Adobe Premiere

In the premiere for the first time, I want to make a small video presentation, I made several video captures with movavi recorder, overtook mkv to mp4, looked at their quality, started cutting, I already noticed that the pieces that I insert are of poorer quality, and when I did the final export, it turned out to be a video quality ala 144p with 2 min 35 sec 560mb ... Tell me

in these questions - how to import without losing quality and how to get the finished video in good quality?

And then I did everything as I planned, but the quality is complete ... r, although the sources are of normal quality ...

Yes, I also noticed that if you press play in the editor, the quality is bad, but when I press pause anywhere, the frame becomes of good quality, maybe it remains only to configure the export correctly?

Answer 1

The default preview is in reduced quality, so that it works on the "calculator"
When exporting, select the normal image parameters, it will render
What export parameters do you set?
