LUMIX Tether Video Recording Stops Unexpectedly

This is a focused fix for one specific LUMIX Tether problem: LUMIX Tether Video Recording Stops Unexpectedly. Walk the list top-to-bottom — the first item is the most common cause in support tickets.

Root causes, in order of frequency

1. V90 card needed for 5.7K/120p
2. Disable 4K continuous limit in EU regions (older fw)
3. Thermal throttling — keep fan on, lid open

Confirm the fix

After each step, close LUMIX Tether completely, unplug USB for 5 seconds, replug and relaunch. The connection state is cached — without a full power-cycle of the link you cannot tell which fix worked.

Still stuck?

If none of the above resolved it, swap the cable for a known-good USB 3.2 Gen 2 cable (this fixes ~40% of remaining cases) and reinstall LUMIX Tether v2.12 from the how to tether. Related: main download page. streaming setup.
