No Video only Sound with Resolve newer than 18.6 SOLVED

I have got no Video at all in Resolve with any version newer than 18.6 with my MBP 16 I7 5600m GPU. Any Ideas? Choose dedicated gpu in preferences and switch between metal and openCL - all tested no video success. Any ideas? Any routine or log to check whats the matter? thanks folks

No idea?

Studio or Free etc?

Of Course, thanks for your reply. 20 Studio Version, MAC 16" 32GB 2019 Sequoia 15.3.2, Premiere is running with the card without problems, but I prefer Resolve....

What videos and video codecs have you tried?

Does these two work? https://we.tl/t-RQBZPlATJg

Yes no Video only black. Is there an user mistake? Some checkbox not activated? 18.6 is running without problems, 19 not 20 not.

Three things: 1) The "npasse" is german for "fit", correct?

2) Do the image work in Fusion?

3) Otherwise I think we are back to needing logs (see FAQ for how to create them).

But I'll be honest, I have no idea there the image is sent to. Any declink? external devices? Clean feed out?

Ohhhh it was really the bug that Resolve 19 / 20 don´t like or can´t choose diskret or intel gpu. Now it´s working. Thanks for your help! Rare monday morning success
