- How do you generate a video?
- How do you edit, download, or share the generated video?
- How do you customize voice, language, and speaking rate?
- What are best practices for video generation?
- Are there any limitations to the video generation feature?
📌 You can generate videos alongside other content types in a single request to Sparky.
How do you generate a video?
-
Navigate to the Flint home screen and start a new chat or activity with Sparky by clicking on "My chats" or "My activities".
-
Ask Sparky to create a video by using the chat box
(e.g. "Generate a video on the American Revolution for my 6th grade class")
-
Optionally include a document or link for additional context using the plus icon. Click on the paper clip icon to attach files from your computer, Google Drive, or Microsoft One Drive.
-
Let Sparky create the video
It may take a minute or two for Sparky to generate the video. Do not exit out of your window while Sparky is generating!
How do you edit or download the generated video?
You can make modifications to the video by simply asking Sparky. In this example, I've asked Sparky in the chat box to make my video on the American Revolution focus more on key events in a timeline format.
To download the video, click the download icon that appears above the generated video.
How do you customize voice, language, and speaking rate?
Generated videos also support custom voice, language, and speaking rate settings. There are two ways to customize these:
When generating videos within an activity, Sparky automatically uses the activity's configured voice, language, and speaking rate. To change these defaults:
-
Open your "Activity settings"
-
Click "Build Manually"
-
Click "Language"
-
Configure your preferred voice, language, and speaking rate
There are currently 9 available voice options, each with their own tone and style.
-
Click "Update activity"
Any videos generated in that activity will now use these settings.
You can also request specific voice, language, or speaking rate settings directly in your message to Sparky, which can occur both in chats and in "Build with Sparky" for activities.
For example:
- "Generate a video in Spanish about photosynthesis"
- "Create a video with a slower speaking rate for my ELL students"
- "Make a video using the Blake voice"
Both the narration and any on-screen text will render in your selected language.
What are best practices for video generation?
We suggest that you...
Be specific about the audience, including things like grade level, background knowledge, and learning objectives. You can also provide context such as:
- Pasting notes or curriculum text
- Attaching documents, like a syllabus or slides
- Including links to readings or resources
Additionally, you can ask Sparky to include examples, analogies, or step-by-step explanations in the video.
When you want Sparky to make a video, make sure to use language like:
- "Create a video on..."
- "Generate a video about..."
- "Make a video that explains..."
The clearer you are about what format you want, the more helpful Sparky will be!
You can request videos along with other materials in a single message:
- "Create a video on photosynthesis and slides that go into more detail on each step"
- "Generate a video introducing the topic and a quiz for students to complete afterward"
Are there any limitations to the video generation feature?
Currently, there are a few limitations to the video generation feature:
- Videos are approximately 90 seconds long
- Currently, videos do not have the watermark feature
- Output format is MP4
- Video resolution is 1236 x 1024 pixels
