I would max. Invest 1200 euro.
Why laptop?
Is that really necessary?

Then 200 euro for monitor.
If you are looking for mobility, then orient yourself to "gaming notebooks", which have not the power as high-end gaming PCs (in terms of graphics processing) but still, in particular for video editing even better than the "normal"
What does he want with a gaming computer? There's clearly music production. Investing money in an unnecessary graphics card and, for example, on the desktop only a Ryzen 5 2600 makes in this application for 1000 euro but no sense.
So video editing is a completely different house number than making music.
It does not have to be an expensive calculator, as has been said here, when it comes to music.
An Intel i5 processor should be enough, if music is the thing, Fruity Loops runs on a Duron 800 single core ;-).
Video Editing: Fast multithreading capabilities, lots of RAM, fast HDD, best SSD - then you can quickly get to the budget limit. Would then synonymous for video editing synonymous rather recommend a normal PC / tower, because you kansnt better and can also cool better. This is hardly possible with a laptop.
A lot of people who cut videos use APLLE devices, but that's where you get to the budget line quite quickly.
"There's clear for music production."
Which laptop is best for producing and music
Video edited suitable? "
Of course that is there. But there's more. Maybe a video card for video editing is not so unnecessary.
