Export all logged takes as a PDF production report or CSV file for sharing, archiving, and post-production reference. PRIVACY Pro Slate does not require an account. Production information is stored locally on your device and is exported only when you choose to share it. IMPORTANT Pro Slate generates display timecode using the device. Unless connected to and verified with supported external equipment, it should not be treated as a certified master clock or a replacement for dedicated hardware synchronization.
