Frequently Asked Questions

Does lowering video resolution reduce file size?

Yes. Downscaling video dimensions (for example, from 1080p to 720p or 480p) reduces the total number of pixels per frame, which substantially lowers the resulting video file size.

Can I change video resolution without stretching or distortion?

Yes. Select "Fit to Resolution (Maintain Aspect Ratio)" or a percentage scaling option to preserve your original aspect ratio without distortion.

Are my video files uploaded to any server?

No. All processing happens 100% locally in your web browser using HTML5 Canvas and MediaRecorder. Your video never leaves your computer.
