[78-L] Making of the EMI centenary Wax recording - some questions

[Milan Milovanovic]

Hello members,

two days ago I watched this clip:

After carefully watching it some questions raised, so I would like to ask if anybody knows:

1) Is this, in fact, making of acetate disc recording, or I'm missing something here? It is clearly shown acetate/nitrate/lacquer disc as recording media, not wax discs. These are shown earlier in the clip, but I haven't seen them later during the final stages of making the recording.

2) (slider position 0:31) Is it really inside start disc? What can be seen here on turntable - is it vinyl translucent pressing or acetate/celluloid/vinyl foil? No lead-out groove? Is it some other recording? 

3) (slider position 1:45 - 1:50) Are they making lead-out groove with locked groove after?

4) (slider position from 2:23 - 5:02) Some strange noises occurred. Is this reproduction of acetate master through acoustical player?



Thank you,

Milan
