1How the two differ

Open-Sora 2.0's docs say nothing about camera moves, while Pika reads “Words in the prompt” on camera moves. Open-Sora 2.0 reads “First frame only” on start and end frames, while Pika reads “First and last frame” on start and end frames. Only Open-Sora 2.0 documents a motion setting. Open-Sora 2.0's docs use 1 of the site's camera words and Pika's use 4, with none in common.

2The differing points, in the docs' words

How a camera move is asked for

Open-Sora 2.0: the docs read do not cover this.

Include sexy keywords in your prompt, like bullet time, vertigo, timelapse or dolly down.

Pika, FAQ

Shot sizes and angles in the docs

The camera angle provides a bird's eye view of the waterfall.

Pika: the docs read do not cover this.

Start and end frames

Given a prompt and a reference image, you can generate a video with the following command

HPC-AI Tech, Open-Sora repository

Pikaframes is a stunning image-to-video feature that allows you to upload the first and the last frame as still images

Pika, FAQ

A setting for how much the picture moves

During inference, you can use the following command to generate videos with motion score (the default score is 4)
