I have no proper VCR to record and play 405 lines.
But I have found one that will record short clips of 405 lines poorly and another VCR that will play them.
A short video at this link of play back of the 405 lines and conversion to 625 lines. It is actually better than I expected.

The VCR's are fairly modern and far from ideal. The record one appears to have some form of black level clamp that goes haywire when it sees a 405 signal. As times goes by the recorded sync pulses gets shorter eventually disappearing altogether. With the result I can only record just over a minuet with sync pulses. There is also line tearing.
