Compare usable results, not demo galleries
A polished example gives you a starting point. For an AI video generator, check whether the result holds its character and scene together through the whole clip. For an image tool, compare how much control you have over revisions.
- Compare the same input mode across tools: image-to-video and text-to-video solve different problems.
- Check the downloaded file, not just its preview. Look for resolution limits and watermarks.
- Count retries when judging cost; a low generation price can still lead to an expensive usable result.
- For chat, try one ordinary fictional scenario and watch whether the character follows your corrections.
