How to convert MKV to MPEG or AVI with VLC

Closed

Hello,
I just discovered VLC media player to convert videos from mkv format to mpeg or avi...
The problem is that when I start recording while watching the .mkv format, it converts the video to mp4...
So I click on convert/save, then there is a message "open media": I choose my .mkv video and click on convert/save. I need to select the destination file
>>> but I don't know how to do it!!???
Then I skip and select the DIV3 / MP3 or MPEG format and start, but VLC closes the dialog box and neither plays the movie nor starts the recording...
What should I do?
Sincerely, loulou-38

    Thank you... but you are wrong!

    Reducing the size of the video decreases the file size with formatfactory

      Take online bitrate calculators that help you define the size of a video file like:
      - http://www.djengo-website.com/articles.php?lng=en&pg=114
      - https://www.videohelp.com/calc.htm

      Where do you see the parameters regarding the resolution of the video?

      But read on because it's not that obvious, and I don’t claim to know everything, but I believe what I say is valid.

      Then, if you want, try to do an encoding test on the same file that you encode with the same video bitrate but with different resolutions. If you do it right, the final size of each file will be the same even though the dimensions of the image are different. I also believed like you, so after a discussion with a participant, I did this test on the same file that showed me my mistake.

      You notice that only the Qf" (Frame Quality) changes. It's the Bits/(Pixels x Image) ratio. So in the file with larger dimensions, the visual impression makes it seem that the video file is of lower "quality" at equivalent bitrate. The opposite is also true. In short, it's better for this ratio to be high.

      But since everything isn’t so simple, I invite you to read this article if you want: https://cyrille-borne.com/?post/2008/08/03/Bitrate-et-resolution

      I don’t want to debate with you, I just want to enlighten you a bit, because I myself struggle to understand everything as well.

      Finally, I found a small software that seems quite good (but for AVI files only) because it indicates, it seems, which resolution is best suited for a given size, for a specified duration, and more: https://www.videohelp.com/software/VideoHelp-Bitrate-calculator
