Limitations

Clear expectations for browser support, export format, local storage, and hosted sharing before you rely on ChalkReel for important work.

Limitations

Browser recording support varies

ChalkReel uses browser media APIs for recording, camera, microphone, source audio, and final encoding, so behavior can differ by browser, device, and source file.

Chrome or Edge on a laptop or desktop is the most predictable setup for recording.
Mobile browsers and small screens are not supported for the editor.
MediaRecorder, camera, microphone, codec, and source-audio support can vary across browsers.

Limitations

Exports are produced by your browser

The finished WebM recording is produced locally by the browser, so final quality and smoothness depend on the browser encoder and device performance.

Requested quality and bitrate are encoder hints, not guaranteed final file characteristics.
Recording smoothness depends on browser performance, source footage, webcam use, annotations, and device load.
Preview the finished recording before sharing or downloading an important take.

Limitations

Source footage and recordings stay local

ChalkReel can sync editable project snapshots for signed-in users, but original source footage remains a local file that the browser cannot silently reopen later.

Clearing site data, using private browsing, switching profiles, or switching devices can remove or hide local projects and recordings.
Restored or reopened projects may ask you to relink the original source video.
Download finished recordings you want to keep outside the browser.

Limitations

Hosted sharing is intentionally narrow

Accounts support private cloud project snapshots and hosted public watch links, but they do not upload the full local media workspace.

Cloud project sync excludes source video files, local recording blobs, and device-local browser artifacts.
Hosted shares are public to anyone with the link and may include notes, tags, titles, and teaching-point context.
Free hosted sharing is limited to 3 active or pending links and 50 MB per finished WebM upload.
