Error Code/Messages

Description

Application(s) involved

Solution Proposal/Explanation

NO SIGNAL/No signal

Shown in the Channel Viewer and in the Messages section in the Inspector. This is generally the case when there’s no input signal at all or a wrong input signal is present. When using SDI, this means that there is no incoming signal at all or a signal not matching the manually selected Video Format of the engine. For NDI based signals, it means that the incoming IP signal is either not matching the manually selected Video Mode of the engine or in the wrong format (e.g., Progressive vs. Interlaced)

Just In Mac Lite

Use Auto Mode when the Video Mode is not persistent.

WRONG FORMAT

Shown in the Channel Viewer

Just In Mac Lite

The WRONG FORMAT message is displayed when the source signal and the video do not match. Recording is disabled. Change the video mode to Auto to circumvent the error message and proceed with recording.

Dropped frames

Shown in the Messages section in the Inspector.

Just In Mac Lite

Please ensure that you are receiving a proper and stable NDI stream.

Recording stopped

Shown in the Messages section in the Inspector.

Just In Mac Lite

When configuring a channel in the Configuration panel, you can enable the option “Restart on No Signal If Not Recording” to automatically restart the channel after a signal loss.

Depending on the selected behavior—“Close container, write to new” or “Close container and stop”—the engine will either continue recording in a new file or stop the recording task entirely.
