I am struggling with the most streamlined way to save videos into my iPhone’s photo gallery. I have saved in iMovie but I think it changes the format away from 9:16. I posted 2 videos into TikTok and both videos do not fill up the entire screen. It prompts you to turn the phone horizontal. Can someone guide me step by step?

Hey Y’all My name is Thomas and I’ve been using OSSA Ai for faceless videos since November 2024. Thanks to Cole Gonzales and James Ward, I’ve learned many new things about OSSA and AI in general. With the exception of a couple crazy days here and there, I’ve managed to post 1 video a day for the past 60+ days with steady growth organically. I am a proud dad of a son who has autism and supporter of autism awareness, so I created this channel to post about my passion and help others at the same time. I do a lot of research in autism and use my own channel to continue to learn all that I can. So far it hasn’t been a super viral account, but I have a passionate audience that continues to grow. Here’s the video link to my best performing video to date. All feedback is welcome. https://www.tiktok.com/t/ZP8FHQk6g/
