Q: The app keeps crashing! What can I do?

A: Below are some steps you can try.

 1. Close all other apps by double tapping the home button and swiping them up (if you cannot close all other apps, then at the very least close all other Teradek apps).

 2. Close Live:Air by double tapping the home button and swiping it up. Reopen the app.

 3. Make sure all your input streams are good quality. There should not be constant dropped frames or decoder errors. The frame rate should be 30 fps or less. The Input panel displays information about source quality.

 4. Try reducing the number of video clips and overlays in your project.

 5. You can do a full reset by going to the iPad Settings and navigating down to the Live:Air settings.  Enable the option ‘Reset Database on Next App Open’.  Close the Live:Air app by double click on the Home button and swiping up on the app to close.  Now reopen the app.


Q: The input stream is stuttering and skipping frames. What’s wrong?

A: Follow the same tips above for avoiding crashes. Also, try the following:

  1. Make sure all wireless connections between the devices and iPad are robust and have adequate bandwidth. We recommend using newer, high quality wireless access points and configuring networks to use the 5GHz WiFi band.

  2. Lower the resolution and/or bitrate of incoming stream.

  3. Ensure Teradek device firmware is up to date.

  4. Check that your iPad has adequate CPU resource to handle your streams. CPU information is visible on the Input page. If the CPU load is high, reduce the number of streams or their resolution.

A: Go to the Audio panel and check if the audio levels are too low. If the audio source is set to On If Live, it must be selected for audio to be present in the stream.
