Having done a bit more digging for information, I think it was taken at the Odeon Cinema Llandudno in Wales on 14 August 1963.
This was in the middle of a six-night residency in the town which began on 12th August.
On 14th August they travelled to Manchester in the daytime to record video clips of Twist and Shout and She Loves You for Granada TV. They took their instruments, including Ringo's drum kit, with them.
The Twist and Shout clip is here ...
I assume they had to hurry back to Llandudno after the TV recording had finished - maybe they went by car and their instruments came in a separate van.
Having looked at the Twist and Shout video, they don't seem to have taken their guitar amps with them since they were only miming to a pre-recorded song. This explains why you can see the usual Beatles amps in the concert photo (these stayed at the theatre in Llandudno) but they don't have their usual guitars and drums.
You can see that (apart from Ringo) they are wearing the same polo-neck sweaters in the clip as in the photo from the concert later the same day. My theory is that they took their stage suits to Manchester but decided to wear polo neck sweaters for the recording. Since the Beatles normally wore suits on stage at this time I'm thinking that their suits travelled from Manchester to Llandudno with the instruments and didn't arrive back in time for the show, which is why they are wearing their "daytime" clothes on stage.
