Frequently Asked Questions

Which timecode inputs are supported?

Section titled “Which timecode inputs are supported?”
  • You can use any MIDI device which is recognized by your operating system. You may need to restart the application before a newly connected device is available.
  • For ArtNet, just ensure that no firewall is blocking the traffic.
  • For testing purposes, you can also use a Realtime Clock timecode source.

How can I use SMPTE/LTC audio input?

Section titled “How can I use SMPTE/LTC audio input?”

In the initial stages of app development, integrating LTC/SMPTE timecode input via an audio interface is complex, largely due to factors such as driver compatibility, signal variability, hardware differences, and resource allocation. However, there are numerous effective (and often affordable) LTC-to-USB interfaces available, as well as software converters that can transform LTC from your audio input into a (virtual) MIDI device.

For production use, hardware converters are recommended, such as Rosendahl MIF-4, Visual Productions TimeCore, or DOREMiDi MTC-20. The MTC-20 works particularly well as an input device for a very reasonable price.

To use your computer’s audio input, TXL20 Timecode Expert 2 is highly effective:

  1. Create a Receiver and switch to SMPTE
    Ensure your settings at Options > Preferences > Audio are configured for your correct audio input.
  2. Create a Sender and switch to ArtNet
    Set the IP to 127.0.0.1 and ensure no firewall is blocking the connection.
  3. Connect the Receiver to the Sender by dragging a line from circle to circle

A free tool for converting Audio-In LTC to local MTC on macOS is Figure53 Lockstep.

For Windows, you can try GSi SMPTE Tool in combination with loopMIDI.

How to convert Excel time to timecode?

Section titled “How to convert Excel time to timecode?”

Assuming your range offset is set in cell B2 to “01:00:00:00” and your Excel time is in column A (starting from A2), you can use this formula to calculate a timecode string in B2:

=TEXT(TIME(VALUE(LEFT(**B$1**,2)),VALUE(MID(**B$1**,4,2)),VALUE(MID(**B$1**,7,2)))+(**A2**/60), "hh:mm:ss:")&"00"

When creating callsheets in Excel, time entries like “01:20” represent 1 hour and 20 minutes. The formula converts these values by calculating hours into minutes and minutes into seconds.

The formula serves as a template that you can adapt to match your specific callsheet format.

Does it work over the internet?

Section titled “Does it work over the internet?”

Technically, yes.

However, this is not recommended, as CueCollab currently lacks authentication mechanisms. Additionally, internet connections introduce latency, which is problematic when timecode accuracy is critical.

For secure remote access, Tailscale (a VPN that enables computer sharing similar to file sharing on Dropbox) has proven effective for sharing the server machine with team members.

Remote access may be used experimentally, but only at your own risk.

Do not publish the server to the internet without additional security measures.

How can I use PWA, NoSleep, … features via HTTP?

Section titled “How can I use PWA, NoSleep, … features via HTTP?”

Certain web app features are only available in a secure (HTTPS) context.

To use these features in a local HTTP environment, you can configure Chrome to treat specific unsecured connections as secure.

Chrome settings: chrome://flags/#unsafely-treat-insecure-origin-as-secure

How can I uninstall the app?

Section titled “How can I uninstall the app?”

Delete the application CueCollab.app from your /Applications folder.

Application data can be removed by deleting the folder ~/Library/Application Support/CueCollab/.
