I have missspelt som wordz in thise libe.

I have misspelled some words in this line.

Looks like it works.

How many pixels in a 35 mm frame?

There is a lot to understand about image resolution.

If there are 3000 pixels per inch on film, that is equivalent to 118 pixels per mm. (I have heard the film can go to 4000 pixels per inch which is 157.48 pixels per mm.) I will use 3000 dpi for now.

An interesting link

19.4 mm x 29.1 mm = 7.860.655 pixels per frame. (13.9M pixels with the 4K figure)

Now the HDTV display standards call for 720×1280 ( .9M px/F) or 1080×1920 (2.1M px/F) the main difference being that the 720 rate can display a frame every 60th of a second and the 1080 rate only displays a frame every 30th of a second. There are progressive and interlaced display differences as well.

So, if a movie frame has 8 M pixels, then HDTV can display a quarter of the resolution, at best. a movie projector that is going to display a 2.33:1 picture. I need to work this out. Using a 35 mm frame, a movie director want to project a 2.33:1 ratio so that the width is over twice the height. I know I have seen a page somewhere that define how much of a frame is used for the different aspect ratios in a 35 mm frame.

I found one place that scans in 5200×3500 pixels so that is 18.2M pixels per frame. That is 1.5 ratio. for a 2.65:1 aspect ratio we would have 5200×1962 pixels or 10.2 M pixels per frame.

So lets assume that a movie needs to project 10M pixels at 5200×1962 ratio so they need to come up with some advanced projectors and not try to replicate the HDTV displays. And they will want to project at least 24 frames per second, shuttered to repeat the frame twice for an apparent 48 frames a second (this avoids a flickering effect). Although, digital projection can give the director the option of displaying more the 24 frames a second to get different effects. A 72-frame-per-second image looks different than a 24-frame-per-second image, especially if there is motion involved.

To get a 5200×1962 display, you can take an array of DLP chips (currently 1280×720) and synchronize them into a coherent display. 5 chips x 3 chips gives you a potential display of 6400×2160 ( 2.96:1 13.8 Mpx). Turn the chip sideways and an 8×2 matrix gives a 5760×2560 pixel display (2.25:1 14.7 Mpx).

Now I’ve got the “Bladerunner” theme playing with Brakhage. Incredible. The Brakhage piece is titled “Love Song”

It doesn’t work with Glenn Miller.

Elaine suggested I try other movie themes to see if they synch up since Brakhage is painting every frame separately and they are being displyed at 24 frames a second. I can see why this causes some people headaches.

Didn’t seem to work with the Strausses. Seems to work with Schuman.Deinitely works with “Aufschwang” (used in “Heat and Dust”)

Now the “Clockwork Orange” music. Beethoven’s 9th Choral works. The “William Tell Overture is not starting out well. But we haven’t got to the Lone Ranger part. It start to mesh when the storm arrives. Rossini is so derivitive. The morning breaks and the birds and flowers joyfully greet the sun? But still keeping synch. The Lone Ranger has arrived, nine minutes into the overture? It works.

Elgar’s “Pomp and Circumstance March #1” works right from the start. The familiar processional doerns’t snap to as muxh as the rest of the piece, but it works as a whole.

Next we have Canon in D from Pachelbel, used in “Ordinary People”. I am familiar with this piece as a bit of meditative music, but laying it over “Love Song” I think it works. A little more drawn out than the others, but in synch. More like four frames per beat instead of one or two frames per beat.

Now we come to “The Ride of the Valkeries” This will never work… I wonder if Brakhage was listening to Wagner when he composed “Love Song?

One thing I learned tonight. If you want to know if a piece of music will work as a movie soundtrack, run it against some of Brakhage’s films.

I am watching some Stan Brakhage movies, which are silents, with “Tusk” playing in the background and it amazing how “A Study in Black and White” synched up with. Actually the random selection of songs playing synch up very well with these short films.

This is an attempt to put another table in the blog. This time, I saved the page directly from Excel to HTML. then I will copy the source info on the table into the WordPress. Let’s see how it works.

Crikey, Bob! I think it worked. No it didn’t! I’ve been bit…

This is a little table listing the NFL Teams, how many times they have been to the Superbowl, how many wins. Well it might be a little table if I can get it to work. Interesting to explore how to make open standards work with a Microsoft Product, or vice versa.

Nope, Can’t get it to work. I think the MS formulation is too wordy. Maybe I will just put a link to the table. If I can figure out how to save a file back to the server. I’m sure that knowledge is rattling around somewhere.

One thing I found interesting, that in 39 SB, only four times have both teams been SB newbies. 1967 (the first one), 1969, 1982 and 1986.

This WP article, Spammers’ New Strategy (washingtonpost.com) Talks about how some ISPs are letting their machines spew spam.

When I first started reading it, I thought they meant that spammers had taken over the ISP machines and the spam was being generated from Zombies. Easy solution for that, let the rest of the internet block traffic from that ISP unitl they get control of their machines back.

But, as I read it, they appear to be talking about customers of the ISP spewwing spam and not the ISP machines. Since most ISPs have anti-spamming rules, if one of their customers is IDed as a spammer the customer is usually removed from the ISP. That’s been SOP for years, where is the news?

Then it goes back to the ISP machines being used as zombies, using a software product distributed by a customer of MCI, hosted on a machine leased from MCI. So the antispammers want MCI to shut down the source of the software and not the spam itself. Not a good idea.

We can’t have ISPs turning off a customer site just because people disagree with what they have on their site. The ISP is not a content cop, judge, jury or executioner. The ISP should be blocking all spam that is originating through its site. Such spam is identified as email content that gets the ISP domain addressess blocked at a majority of receiving sites such that the ISPs non-spam customers can’t use email effectively.

Mail that is being sent with spoofed address/header information is spam.

I suppport blocking the source of spam, the so-called ‘blacklist’ approach, and it should be blocked as close to the source as possible. If that means blocking an entire ISP that doesn’t have control of its machines, so be it. Let them fix it or lose their customers.
