Something like ‘Adobe Creative Cloud’s Premiere Pro’ is great – it’ll cost you a pretty penny – but it’s worth it. However, remember that these are incredibly powerful professional tools and may take some getting used to. It might be better to take some baby steps with something like ‘Final Cut Pro X’ or enroll in a course.
Keep at it – keep focused and keep learning. Harness your creativity and soon you will be video editing like a pro.
