4-Way automated masking masks every AR perfectly. (In my system I can make as many pre-sets as I want, currently up to around 20 or so...though I can always jog the masking to fit as necessary as well).
BTW, boy that sounds like a fun and rewarding job. (Well, it would be so long as you like film, which you clearly do).
Correct it is difficult with just one movable masking system, but with two its always easier to not crop any aspect ratio. I have worked in many cinemas that employed movable top and side masking, these were usually cinemas that had the facility to screen 70MM. 70MM always looks more impressive if one has movable top masking as one really wants to project 70MM on a larger screen than scope.
I only had room for movable side masking with stops in my cinema at home, but I can jog the masking to any size if I want and screen all films in exactly the correct ratio without any cropping, why I don't is simple..... Coming from a background in the cinema, I want to do the same at home in keeping the smaller ratios like 4:3 physically smaller than 16:9, and 16:9 smaller than scope. If I was to screen say a 70MM film like Lawrence of Arabia in its true ratio, I would have to screen it smaller than my scope image, that's why I crop like cinemas do.
Many70MM cinemas that never had movable top masking cropped the sides of their 70MM films to fit their scope screen just like me, they didn't want to end up with a smaller 70MM screen by just bringing in the side masking. Its all about impact, scope and 70MM films should look as they were designed, larger than 4:3 and 16:9. In a cinema one was showing many different formats within the one programme, following those rules works when you are aiming for impact.
It however can differ at home when some may just screen a feature only, no trailers, shorts etc etc....Playing a "feature only" 16:9 movie (no scope trailers, shorts) and raising ones movable top masking to make the 16:9 larger is absolutely fine, the audience is not seeing say a smaller scope in the same programme. Its all about presentation and there are absolutely no rules to follow. I'm only speaking about the rules that used to apply in top run cinemas of yesterday, supermarket screening rooms (cinemas) of today don't follow any rules, they don't know or even care, its a sad state of affairs.
I follow those old rules we once had in the cinemas at home and presentation like we once had in the cinemas I also duplicate in my cinema at home.....bring back the magic I say!
Times have changed sadly:rolleyes:
