Oddball tripod thread

[black*max]

Bought a no-name video camcorder, weird thread for tripod mount, not 1/4-20, anyone know what it is?

I have 3 different types and all are 1/4-20 but had to get an adapter for my larger reflector telescope, it was a small threaded slug that converted 1/4-20 to 3/8-16.

Thanks but it's not 3/8, it must be a manufacturer error, so kind of metric.
