Does CalmClip upload my video to a server?

No. CalmClip processes everything entirely inside your browser using WebAssembly. Zero bytes of your video are ever sent to any server. Your files stay on your device at all times.

Is CalmClip free to use?

Yes. CalmClip is completely free. No account, no subscription, no hidden fees. Open the site and start editing immediately.

What video formats does CalmClip support?

CalmClip supports MP4, MOV, WebM, and MKV files. All editing and export happen locally in your browser using FFmpeg compiled to WebAssembly.

How does AI transcription work without uploading my video?

CalmClip runs the Whisper speech recognition model locally in your browser via WebAssembly. The AI model downloads once and runs entirely on your device, so your audio never leaves your machine.

Can CalmClip handle large video files?

Yes. Because CalmClip processes files locally using FFmpeg compiled to WebAssembly, it handles large files (1 GB and above) without upload delays. Editing starts immediately after you select the file.

Does CalmClip require an account or login?

No. CalmClip requires no account, no login, and no registration. Open the site, drop your video, and start editing.

What ratios does batch export produce?

16:9 (YouTube, landscape), 9:16 (TikTok, Reels, Shorts), 1:1 (Instagram feed), and 4:5 (portrait feed).

Does batch export require Pro?

Yes. Batch export is a Pro feature.

Do all ratios get the same edits?

Yes. Trim points, silence removal, captions, and audio normalization all apply to every format in the batch.

How long does a batch export take?

It depends on your CPU and the length of the video. Each format is exported sequentially in your browser.

Will the crop be different for each ratio?

Yes. Each ratio has its own crop, which CalmClip sets automatically or lets you adjust manually.

Can I export to only some of the ratios?

Yes. Choose which ratios you want before starting the batch.
