My grandmother and I have making YouTube videos for about 2 years now. Here's an 8-hour long unedited video. It contains our first 100 videos. I would have tried to edit some of the parts, but since it is almost 8-hour long video, I was't sure if it was going to render it. In fact it only rendered on my fourth try. 1 render took about 10-20 hours. The video is around 120 GB. My first mistake was to render it as bigger than 128 GB file which YouTube doesn't allow.
❗❗❗ IMPORTANT! Do not forget to turn on the subtitles.
