FAQ

In addition to entering a prompt in the input field on the home screen, you can generate a video by using a sample or one of your own generated videos as a reference video, or from files such as documents, scripts, audio, videos, and images. For details, see: https://no-lang.com/en/tutorial/generation-methods

There are two ways to generate a video from text: "Prompt" and "Script". With a prompt, the AI generates a video based on your question or instructions. When you generate from a script, the text you enter is read aloud in the video exactly as written.

For PDF and PPTX files, you can generate a video using either "Explain every page" or "Explain key points only". Please see the samples for actual videos.

By uploading a WAV or MP3 file with audio, you can generate a transcript or a video in which an avatar speaks in sync with the uploaded audio. Please see the samples for an example of the finished video.

With Generate from video, you can upload an MP4 video file to generate a video in which an avatar speaks along with the transcription or the audio of the uploaded video. See the samples for actual examples.

A horizontal video has a 16:9 aspect ratio. A vertical video has a 9:16 aspect ratio and is a video format designed for mobile.

Yes, you can change the aspect ratio of a video from the editing screen. Go to "Edit" on the video page and change the aspect ratio at the top of the screen.

We offer a feature for uploading "Live2D avatars" and "VOICEVOX standing-portrait avatars".

Standard videos are provided under the CC-BY-SA license, and commercial use is permitted as long as you copy and clearly state the copyright shown on the video page. However, for summary videos of web pages created with the Chrome extension or similar tools, please refrain from commercial use or posting to other media, due to the rights attached to the original article.

On the video page, click the "Share" button and set the video's sharing setting to "Anyone with the link" to make it public. To make it private again, change it to "Only you can access".
If you want your videos to be public by default, turn on "Video visibility" in the "User Settings" tab on My Page.

Yes, you can upload them. When you do, however, you must include the copyright information in the description or a similar place, so please do not forget. On the video page, open the toggle labeled "Copyright" in the description, press the "Copy" button to copy the copyright information, and paste it as it is.
If the copyright information is too long, issue a share link for the video instead: see "Q. How do I make a video public?", set the video to "Anyone with the link", and paste "Copyright: <share link>".

We use images that are free of copyright issues, but if an image later turns out to have been published without authorization, we will notify you by email or another means. The same applies to background music. For text, the license and copyright depend on the PDF or the web page itself when using the Chrome extension.

On platforms such as YouTube, fraudulent groups that claim rights even to free-share and public-domain audio are widespread, so videos are sometimes falsely flagged as infringing copyright when posted.
You can file a dispute, but processing it may take some time.
For that reason, if this happens, we recommend using different background music or uploading audio that you have downloaded yourself.
