Most of these tools aren't really substitutes for each other. These pages explain what each one is built for, including the cases where a competitor is the better pick.
InVideo is an editor with AI in it, built for control over how each video looks. ShortFast is a pipeline, built to produce and publish without you opening an editor at all.

Learn moreShort-form video tools split into roughly three groups, and most head-to-head comparisons you read online confuse them. Clippers take long footage you already recorded and cut it into shorts. They're excellent if you run a podcast or stream, and useless if you have no footage.
Editors give you a timeline, templates and control over how every frame looks. They're the right answer when a video is a deliverable someone signs off on, and the wrong answer when editing is the thing stopping you from posting.
Pipelines like ShortFast originate the video from a topic and publish it on a schedule. The trade is control for consistency, which is worth it if your problem is that you didn't post for three weeks, and not worth it if your problem is that videos don't match a brand guideline.
Work out which group your problem belongs to first. It narrows the decision faster than any feature table.
