Arena's Video Generation lets you compare two anonymous models in a head-to-head competition to see who can create a better video based on your prompt. After you submit your prompt you'll be shown both model's generations where you can vote on which you prefer. These votes are what power Text-to-Video and Image-to-Video leaderboards.
The Video Arena is available on Arena.
Log into, or create, your Arena account. You must be logged in to use Video Arena.

Login required. Video generation is only available to logged-in users.
Video Arena is currently limited to 3 generations per 24-hour period. This limit may change over time.
Video Arena is Battle mode only. Video Arena does not currently support Side-by-Side or Direct mode.
Generated videos are typically 5-8 seconds long.
Video Arena supports one image upload per prompt. You’re unable to specify what frame this image is used for.
Not all models support audio output. Because Battle mode randomly selects which model you’re paired with, audio output may vary from generation to generation.
