Sure, if you have one. And if it’s presentable. If it’s blurry, shaky or has poor audio quality it may be rejected.
If you have produced a high-quality trailer, you will need to have a YouTube account because you will be prompted to input your video’s YouTube link in order to get it to play.
We look forward to seeing your video. Please make sure it complies with our decency rules, which are: No pornography, no murder, no racism, no bullying, no child abuse, no demonology, no rape. We’re just not interested in those things.
