I wanna learn adobe premier pro

all of the above are true and great responses.

You have be really motivated personally cause it does take a ton of time to get the basics down pat ( how to match source, project setttings, and export settings ). And tell story.

The good thing is that when you first do your first edit to tell the story ( it's like working with a microscope and editing frame by frame etc... kinda tedious ) and then you play it back ( with sound ) a magic thing happens..... you see your work and it's really smooth and fluid and you don't see the cuts you made but you see the story unfold.... and it's really beautiful !  Then you'll be hooked.

how much time it may will take me

At least a couple of years: Its not just how to use the program its also all about how to edit the footage: making it into a good story.

Been using Premiere for 20 years now and still figuring things out. Especially with new features.

I recommend a solid subscription service like LinkedInLearning.com, used to be Lynda.com. They have vetted, solid, and accurate complete tutorial series on editing with Premiere Pro. A couple months subscription and diligent work on your part would move you a lot further forward than anything else but working with an experienced editor.

Phillip is right. There's a steep initial learning curve to a full pro NLE like Premiere. Just remember ... after the initial period, it only get's steeper. Sigh. But you're already doing a lot of work by then.

Been editing for close to 15 years. Plenty of people here that have been doing it longer than that. You never stop learning 😉
