This measurement setup in this video is very WRONG, signal feeding is from a too low impedance for parallel resonance.
On MY Ferrite page you learn how-to-do-it the right way. That is feeding the generator signal to the L-C
with a very small TOP-C with a value of 1% of the parallel Cap or even less, even down to 0.1% with a good Q.
In this way the Q damping by the 50 Ohm signal source is minimal and what you measure is much more realistic.
You can even measure a reliable Q.
