Frequently Asked Questions

Find Quick Answers

What video formats are supported?

The tool generates videos in MP4 format with H.264 encoding, which is compatible with all major platforms and devices.

Can I use my own avatar instead of the default ones?

Currently, the tool uses pre-trained synthetic avatars. Custom avatar integration requires additional setup and is not available in the standard version.

Is there a limit to the text length?

For optimal performance, we recommend keeping scripts under 1000 characters. Longer texts may require additional processing time.

What image formats can I upload as background?

You can upload JPG or PNG images. For best results, use images with a 16:9 aspect ratio (1920x1080 recommended).
