Frequently asked questions
- Are the videos sized for YouTube Shorts?
- Yes. CineMix defaults to a 9:16 vertical frame built for the Shorts player. You can also generate 16:9 if you want a clip that doubles as a long-form intro.
- How long is each clip?
- Each generation is a focused 4–5 second scene — ideal as a Shorts hook or a complete short. Build longer pieces by generating several and stitching them in your editor.
- Can I monetize Shorts made with CineMix?
- Pro and Studio plans are watermark-free and include a commercial license, so your clips are ready for a monetized channel.
