PROMPT GUIDE

Sora vs Veo (Prompts, Audio and Where You Can Use Them)

Sora and Veo are often compared as video generation AI from major companies. Both can make short videos from text prompts, but they differ in which apps you can use them in, how they handle audio and the best way to write prompts. Without asserting specs, this guide covers how to choose and how to compare them.

The short answer

Sora is OpenAI's video generation AI and Veo is Google's. Both can make videos from text, and some versions are described as generating audio along with the video. Where they are available, clip length and pricing change, so check the official sites, and compare by trying the same prompt on both.

What is the difference between Sora and Veo?

They come from different companies and are available in different places, and they also differ in how they make audio and respond to prompts.

Sora is OpenAI's video generation AI, used from ChatGPT, its own app and elsewhere. Veo is Google's, used from Gemini and other Google services. Newer versions of both are sometimes described as making dialogue and sound effects together with the video, but availability varies by region, plan and version.

Rinka's tips

  • Country and age requirements and per-plan limits can change. Check the official help before use
  • Making videos of real people requires their consent. Always follow the service's rules too

Does prompt writing differ between Sora and Veo?

The basics are the same: write who, where, what they do, how the camera moves and what sounds are heard, in that order.

In versions that can make audio, you write dialogue in quotes and describe the sounds you want to hear, such as rain or waves. How faithfully this is reflected depends on the service and version, so start with short sentences and add what is missing a little at a time.

Prompt example for comparing: A girl with long light hair and a red ribbon stands by a window on a rainy evening. She looks outside, then turns to the camera and says softly, "It is still raining." The sound of rain on the glass. The camera stays still.
What it asks for: a girl by a rainy window looks outside, turns to the camera and softly says one short line, rain sounds on the glass, and a camera that does not move.

How do you compare Sora and Veo?

Steps to compare the two with the same content

  1. Decide on one scene, with one motion and one short line of dialogue
  2. Prepare the same English prompt and use the same aspect ratio
  3. Make one clip each in Sora and Veo (check where they are available and your plan first)
  4. Compare whether the face stays the same, the motion looks natural and the audio is in sync
  5. Change just one thing you noticed and make one more clip with each

Matching conditions is key when comparing. If you use a longer prompt or a different image for only one of them, you won't know which one actually suits you.

What are common mistakes and how do you fix them?
