You do what you can with you have.
If you can make that have a glimpse of a quality product, you have it made. Scalability is a big deal, but in the end I have seen 480i DV footage launch people off in the right direction.
Just be happy filming your personal project and doing your best to make them unique.
Cause it is that drive and commitment is what producers want.
Even Spielberg was happy at one point filming plays in his backyard.
It all depends on what you are shooting and what you need.
You can always get away with cropped sensors and small dlsr bodies.
But if you needed mounts, sync audio, xlr, to put the monitor off camera, better native iso, extra resolution for down sampling.
At $8,000 and about 3 pounds that is insane.
Sure the URSA has raw, but I personally would want the lighter camera with better resolution that will be more sharp when needed.
Would it even matter?
I am sorry, but any time I hear about the oppressive use of cultural appropriation I cannot take it seriously.
While I totally understand why people feel that way, Art is freaking Art and people are totally free to use any influences they want to create it.
To limit Art like that is completely an silly perspective as even regardless of what aspects are taken your audience will always bring more to the table.
I would just contact your local acting agency, what type of talent on set for very reasonable rates
Typically I go for a good type casting when I comes to new actors.
That way they won't have to anything terribly complex, So they don't have to make complex stretches that lead to bad acting.
It's important to spend time with your actors, new actors to spend even more time getting to know them as a person and see how they act and react with in life.
