when I upload to YouTube the video doesn't upload in full 1080p quality. I filmed my content on a GoPro Hero 9 in 1080p resolution, I use my iPhone to get the videos off my GoPro using the GoPro app, these videos were then saved to my iPhone photo library. I then used my MacBook Air and the iMovie app to make the video. I added music to the video, the video was 3:07 mins long. once I'd made the video I saved it from iMovie to my document files. The first time I saved I saved in the best quality possible, the video was 3.29GB big for some reason. I tried uploading this video but the quality wasn't good, so I thought it could be the size of the video. I managed to size the video down to 429.8MB which showed the same good quality as the original, this was done by saving the video when having it open in QuickTime player( I exported it in 1080p). I tried uploading this video next and got the same results. so any help on why my video isn't full quality, the vid is pixelated, its as if the video is set down to 720p even though its selceted in 1080p. Any advice on YouTubing, editing, uploading etc would be helpful as I'm new to all this.
Cheers in advance
