I don't know how to publish videos with high quality

[Edwardstark]

I read online and tried a lot of software, because I just learned about video so I don't know which software publishes the best video of high quality.

Yeh be careful about that one

I don't know which software publishes the best video of high quality.

Well that's a little difficult to answer with such little information. It's probably more about the settings than the program.

What are you trying to do? blu-ray/dvd/video to mp4/mkv/avi? What programs did you like the 'feel' of? What was it about these programs you liked/disliked?

That's what I'm thinking. Encoding isn't simple.

Just a couple of generalities (if you intend to, say, publish to Youtube, for example):
1. Start with the highest quality original or transfer, maintaining high quality throughout (means lots of drive space consumed for high bitrate stuff).
2. Maintain high quality throughout editing/compositing/processing workflow by using lossless, or near-lossless, intermediate files.
3. Process as minimally as necessary, with fewest round-trip changes (aka do least harm)
4. Determine best quality option for upload channel and only convert to it once from D.I.'s (from #2 above). Perhaps even going higher than native rez/rate, to see how publishing channel behaves with it.
5. Test, test, test. - changing only one variable at a time.

Could give you more, but you'll need to give much more details about your intentions and your current setup & workflows.
