Agreed about the author being somewhat long winded. He claims that film (not digital film but the exposure type film for movies) actually has burred frames. Am I correct to assume hat he is wrong? His assertion is that the blurring is actually necessary for us to see it smoother than the flip page child frame by frame type collection of still photos.
In a sequence of 24 (or 30) frames, it is possible, even likely, that some of the fames will be blurred due to motion. THis would be a function of the shutter speed of the camera. While the film camera is recording 24 fps, the video camera is recording 30 fps, the shutter speed (which along with lens aperture controls the amount of light reaching the focal plane) can be faster or slower. You wouldn't stop much action at 1/30 second. Sometimes when you ramp up shutter speeds you get some odd staccato-like strobing effects-- think of race video, typically shot at high shutter speeds.

I saw some of those early stop image animations with puppet soldiers made in the 1940s (out there on u-tube someplace). They take a photo, then move all the puppets and animal figures a tiny bit and then take another picture and so on and so forth. It looks jerky no matter how small the movement.

You're talking about stop action animation there, where a series of stills is played together, flip book style to create the illusion of movement.

Doesn't this mean that blur is needed or does it mean we just have to jack up the frame rate to 220/sec? I have been piloting an aircraft when a blur goes by of another aircraft I wasn't focused on. Maybe the blur is just a function of focusing more than speed but it's interesting to think about it.

/
I do have a tendency to believe we "stream" rather than shoot a series of still photographs we translate into motion in our brains because: 

1. I remember those strobe lights in the discos several decades ago where each flash shows you a picture of reality but NOBODY, even though they are dancing and jumping around, looks like they are moving!

2. When I look at a physical object versus what is on the screen of a computer or television, the resolution simply does not compare. Reality seems to be a lot more nuanced, pixelated or whatever than a frame by frame series of pictures.

3. Looking through a window is still far better in detail than looking into a digital screen at a movie of looking out a window. Something is still missing (besides 3D).   

Part of what you are talking about is resolution. HD image sizes are much larger than SD (standard definition) sizes. At the standard data rate for HD (19.4MB/sec. according to memory) you can fit five SD channels into the space occupied by one HD stream. And no, I am not a video engineer, but my job has required I pick up a certain amount of this arcana.

Now the equipment manufacturers are pushing new data-rich lines of image acquisition, 4K and 8K, which besides requiring escalating amounts of memory and computer processing power to handle and manipulate, seem to be nothing so much as a solution shopping for a problem. I hope to be well retired before having to transition another production facility to one of these data monsters. 4K appears to be the developing standard for feature filmmakers using digital acquisition.

For comparison, a chart--

Welcome anti-republocrat!   ;D Feel free to post on any subject you wish. Stimulating discussion is encouraged. Our job is extract Homo sapiens from the miasma of stupidity and tyranny that we have been visited with by allowing our psychopathic predator humans to run ragged over the planet and its resources.

ALL major industrial high thermal heat, beat and treat processes ALREADY use electrical furnaces because those are the most efficient for processing and manufacturing metals and their alloys. So ALL of heavy industry, except for back up generators than can run on ethanol, can be powered by ELECTRICITY.
I think that is a real "killer app" for kickstarting demand, making ethanol-powered ICE electrical generators.  It's something that can be done today by someone with good engineering skills (or enough money they can hire someone with such skills).  Alas, I have neither the skills nor the money.  But one thing that makes ethanol ideal for back-up generators is that the fuel can be stored indefinitely without special processing; even with additives gasoline can only last a couple years in storage.  (Propane itself does not degrade with storage, but the seals do, so you can find your tanks empty even though you never used them.)

I suspect that Brazil my have some generator models that run exclusively on ethanol. They already require their filling stations to have at  last one E100 (100% ethanol - illegal in the USA - LOL!) pump. So if they have a large percentage of cars running on it, it's not a big step to rig up a car engine to run on ethanol.

I'll check around when I get some time. To me, the ultimate poison pill  ;D for the fossil fuel industry in the USA would be a legal internal combustion engine made with alloys that cannot handle high temperatures (i.e. VERY cheap to manufacture due to less tempering required and also because it requires 30% LESS metal -  weighing at least 30% less). Any gasoline use would warp the block and/or the heads. So, they would have to be placarded with the "ETHANOL (E!00) ONLY" warning stating that any use of gasoline voids the warrantee.

The same thing applies to natural gas or LPG. LPG and Methane burn cleaner than gasoline but the waste heat problem, while not being as bad, still requires high heat handling alloys and over engineering we have in ALL our fossil fuel powered internal combustion engines today.

Of course the USA will be the last to allow such an ethanol only engine  across the border. The feds will arrest you for carrying "non-fuel grade" fuel (i.e. if you can drink your fuel, Lord Lucifer and the Fossil Fuel Government will frown on you with extreme prejudice    ).

The fossil fuelers will never admit that the waste heat of fossil fuels, so necessary for them to claim they have a "higher energy density" than ethanol, is useless for obtaining mechanical WORK from an engine AND SUBTRACTS from engine power BECAUSE some of the engine energy must be used to COOL the engine.

Hess's Law of enthalpy of formation, the one Charles Hall adores and the one used for just about ALL of the assumptions on laws of thermodynamics in science today, classifies ALL heat, whether waste heat or not, as ENERGY. This is true. But if you can't use some of that energy to do work, and if that energy you can't use actually INTERFERES with you doing work (i.e. SUCKS ENERGY from the energy that is useful in order to keep the engine from over heating), then basing ERoEI on Hess's Law is thoroughly misleading.

finally, Hess's Law is not used as it should be to subtract the energy required to bio-remediate the damage that pollution products from fossil fuels cause. Externalizing those costs as if they did not require an energy input to assure a viable biosphere is an insult to the laws of thermodynamics. It's fossil fuel industry cherry picking, not science.

Welcome GCHandy!

Since I live in Vermont,   a state that was a republic for a while, I think I understand how you might feel.

Regardless of our political situation, if we don't get the 1% to accept their responsibility to fund the lion's share of a global transition to 100% Renewable Energy, we aren't going to HAVE a viable biosphere to fight over.  :(

I am interested in your take on the article below.  :)

AG, what you are doing in here is amazing, just in the couple of days it has been since I visited. You certainly know how to build an interesting forum.

Great work, and fascinating. There's just not enough time to do it all justice.

Surly,
Thanks. Yeah, I'm starting to get my act together here.  ;D  My goal is somewhat amorphous beyond the very specific and daily desire to do whatever the Boss upstairs wants me to do. There are quite a few nature articles I wrote at my DD channel that I plan to publish here in nice, easy to reference "Wonders of Nature" topic categories so that people can go and just relax and lay back with nature video or strange and wonderful info on all the critters we share the planet with and the many biomes they inhabit. I hope to have a fun, as well as informative, general nature audio/video/article library that doesn't require a degree in biology (or any other science) to enjoy. One day at a time.


As to subject matter, I am trying to find a niche that people will feel comfortable going to for interesting, stimulating, enjoyable and at times, righteous anger producing articles, video and audio.

Rummaging around the Admin settings I discovered I have a limit on word count per post. At first I though I would jack it up like RE did at his forum but now I think I'll keep it because it keeps each post from becoming over long and forces me to split posts into parts.

I think I have an advantage as an admin in that I don't dwell on one subject and, quixotic as it may seem, continually seek to provide down to earth, realistic hope for myself and the viewers of the forum even while I holler and scream about some injustice here and there.

I will make every effort to avoid a pitfall in publishing. That is, to concentrate on putting out more material on a subject that gets lots of views. I respect the views but I realize that it is entirely possible for a crowd of 'one subject' zealots to dwell in a certain area. If those just happen to be the ones passing through on a given week or month and I mistakenly assume the other subject areas lack merit, I'll unbalance the subject matter and do future viewers a disservice.

If it's okay with you, I would like to make you a moderator here. No, I'm not asking you to spend more time or do more than you do right now. I realize you have your hands full with the facebook, your channel and the weekly doom load.  I just think it's your right.  ;D

AG, I find that the "quote" function doesn't work in the same way as it does on DD. At least for me.

What is the max word count per post? I haven't posted enough to hit it yet...

Part of your distinctive voice is that you "continually seek to provide down to earth, realistic hope for myself and the viewers of the forum even while I holler and scream about some injustice here and there. " It is what makes you unique, IMO. There is a shaft of light even in the darkest of circumstances. That, plus your rigor in following evidence. (I'm a hyperbole-and-vitriol guy, myself... ;D ;D)

I am honored to be asked to be a moderator. Thanks. Will do my best and will try to match the tone of this fine place.

I'm glad to see you are running with the Forum here AB.  Given the volume of material you produce, it's a better way to catalogue all of it than the Blogs you were using.

Still, there are deficiencies with Forums in terms of how Search Engines look at them.  It is tough to get a Forum "popular" without an associated Blog, or at least a Front Page for the Forum.  You can set up such a Front Page here on Create-a-Forum, I am pretty sure.

Also, you only have 45 days of No Ads on the site.  A Banner will appear on the page pretty soon with Ads.  It's not too bad, and you can also pay a nominal fee to get rid of it, I think it is about $5/mo.

You are welcome. I'm on it!  ;D

As to the quote function, can you believe that JoeP taught me how to use it at the DD less than 2 WEEKS AGO?

Yep, just another little important detail that I hadn't figured out.  :-[

There is another thing that is different here. There is a slightly different video embedding format (it seems easier here). I just tried stuff until it worked.  ;D

http://www.   youtube.com/watch?v=C6YuBh-wAPQ&feature=player_embedded <----USE THIS FORMAT on renewable revolution forum (spaces added so you see the code after www.)

[embed=640,380]http://www.youtube.com/watch?v=C6YuBh-wAPQ#[/embed]   <----USE THIS FORMAT on DD forum

I'm sure there is a way to size the video here like monsta taught me to do at the DD but it looks okay now so I haven't given it any more thought.  8)
