Call me crazy. but I felt Monkey Business, Horse Feathers and Duck Soup all looked rather soft on Blu-ray. Ironically, The Cocoanuts and Animal Crackers look the best of the bunch since they both looked like real 4K scans. The last three movies, on the other hand, don't have that nice fine look. I do feel it was limited to the source and not due to the way it was transferred. I know there was a recently found unedited print of Animal Crackers, which is why this one looked the best. Albeit some bad footages, The Cocoanuts did have the same nice fine look and the scenes that were badly beaten up have undergone an incredible restoration job. Though I don't know why the last three movies don't have the same fine look as the first two. Maybe they couldn't get better sources?
I just discovered that the Paramount Marx films are on Amazon Prime -- no additional cost with a Prime subscription. I watched almost half of ANIMAL CRACKERS last night. The contrast was way off at first, then seemed to get a bit better -- but jut a bit. I assume this was HD -- it kinda looked it, but as I said in another thread DVDs still look great to me.
During "Hooray for Capt. Spaulding", the "I think I'll try and make her" line was still cut out. Weird because when they found the uncensored print you could see that whole scene uncensored on youtube!
I need to view my DVD of that film, but from memory I don't remember the contrast being as bad as what they have on Prime.
Regarding COCOANUTS, I'll have to check the Prime version vs. my DVD. The beat up parts on the old DVD were taken from a beat up 16mm dupe. If they restored these scenes, all they did was find better film elements -- no digital trickery can make a dupe look like an original.
My Marx Holy Grail is an uncensored HORSEFEATHERS and A NIGHT AT THE OPERA.
Regarding The Three Stooges or anything else in HD, blu-ray,1080, 4k, 8k, etc, I think it really depends upon the size of your HD TV screen. Mine is only 1080, and offhand I don't know its size. To me, unless you have one of those giant 10 foot wide screens, or an HD projector to blow it up to that size, I still feel the upgrade from a DVD is a placebo, particularly for B&W films.
For streaming, I'm still not sure that 1080 is equivalent to a blu-ray -- is the bit rate the same? I've seen calcs where you can compress the bit rate and supposedly not see much of a difference. I've read that about 1.5 to 3 gig is enough per for HD. But the size on blu-rays is much more. Again, perhaps the size of your TV matters?
The caveat to all my comments is that I've never seen a blu-ray -- but have seen many films and TV shows in 1080 via cable and streaming -- so it could be apples vs oranges.
