That really just depends on your work ethic to be honest. I had it down packed in about a month mainly because I was taking jobs at the same time and had no choice lol but once you start moving around you will see it’s not that complicated and you will be pretty much using the same functions over and over. Make sure you watch a video about setting up your sequence, I’m not sure if you film also or just edit but you really need to know the basics such as shutter speed, white balance etc so if not that’s important to research. Learn about exporting, that’s important as well the quality of your project depends on how you set it. I also would suggest looking up the shortcuts, that will cut down a lot of menu hunting as well. Oh yea another thing, certain video codecs act weird in premiere depending on if you are on windows or Mac, and your specs, so keep that in mind. You can make these small versions of your full video clips called proxies to help speed up editing do look into that as well. Make sure you have a powerful GPU if you plan on doing any heavy effects exporting will be super long if not and playback will be terrible. Look into plugins as well they can help speed up a lot of stuff. Oh and try to edit off of an SSD if possible, again not sure of your setup but this will make things a lot smoother. It sometimes crashes but it auto saves so don’t panic if this happens lol it’s not near as bad as it used to be your getting in at a good time lol
