I am operating a few TikTok (Douyin) accounts and I think these features of AI Video Generators are important for me as content creators. 1. Video Editing Ability: Edit part of regions of the AI generated videos. For example, when the hands of the humans looks strange or quirky users should be able to edit or modify part of the video instead of generating a new one. 2. Automatic Voice: Automatic Voice is a useful feature which allows the video generation tools to generate voice and subtitles, which should be relevant to the contents of the generated videos. 3. Longer Video Length Restriction: Right now most popular AI Video Generators support video generation from a few seconds to about 10 seconds of high quality videos. None of the tools can promise that it can generate high quality videos up to a few minutes or even hours. So I think longer video length will be extremely helpful.
