I created this fast opener from a template from Envato Elements. It took me a day to do (but would have likely taken me 3 days if doing everything from scratch) and involved branding everything in company colours, uploading 25 videos and adjusting 37 titles and resizing. Quite the job!
I also adjusted the colours and the opacity of tints and overlays, imported the audio and edited the clip so it lined up with the video movement.
It took several renderings and adjustments after all the media was added to get the project just right so was time consuming but pleased with the result.
