<p>I have never had success in saving file with same quality after editing. Either it was much bigger, or quality was worse (square blocks etc). 
I thought MediaInfo program would help, i used to check bitrate of the video, frame rate, codec and make a similar (or close to it) preset in vegas. Never worked.
What i have been using as a solution all these years: save video with high quality, then upload to YouTube and then download from there. 
What are the key characteristics of the source video file i have to check in order to save my editing with the same quality? Maybe there are some good info sources in the internet.</p>

You need to tell us what codec you are using to save. Sounds like you are using a lossy codec, which, as the name implies, involves some loss of quality

@stib i usually use H.264. Is it not possible to detect the codec, source video was made with?

The codec the source video is made with is irrelevant. Once it's opened in the editor it has been decoded to a raster (aka the raw pixels in your video). It then gets re-encoded when you export. Encoding can be lossy for smaller file sizes, or lossless for large file sizes but original quality.

Save video with the exact quality of the source file
