I completed the animation and I took screenshots of it and shared it to myself in Google Drive from where I was able to complete the script, record the voiceover and edit the video and audio in 2 hours at home.Now, that I know how to do the work, I think I can do all of it in a few days.
I also had to research a lot for the facts and the components of organelles since I had to find some interesting facts. I would say the easiest part would be the voiceover, which took me about 8 minutes per paragraph because of mistakes but during the end I was able to say everything in one go. For the editing, I just had to extend or reduce the video and cut the mistakes from the voiceover and then export to my drive.
