How can I convert an mlv file not to mov format?

[Alex3000]

I convert using the MLV app. There is only an option to convert to mov. But my mov doesn't open in Premiere pro. I found how to fix it, I need to convert to h.264+mp4.
The question is how to initially convert to the desired format?

? MOV is a container format, not a codec.

Yes, I have already found it.
Tell me, and in what format is it better to translate for editing in Premiere pro on Windows? In H.264, the video size is reduced by 8 times. This is probably not the best option
