Mini Lab Photo Processing
Christin Baus
Not sure if anyone can answer that question right now, but I would think it's a little light for video work, especially if more demanding software is used. I have been using a 2009 iMac for light video work in iMovie, but any longer projects are moved to a recent 15" MBP, and I don't have any 4K files yet, which we know is in our future, even if you don't need 4K quality, the downsized 1080 files are better than native 1080 files, according to reviews.
As for RAM, I went from 4gigs on my iMac to 16 on the MBP (which also has discrete graphics) so I can't give any comparison of 8 to 16 differences, and I haven't checked the Apple site yet to check out pricing or the RAM non-upgradable issue mentioned by others.

8GB RAM is OK, but 16GB is better for a couple reasons. One if you want to run multiple RAM heavy apps at once, like Photoshop and your video editor for instance. Two, I am hearing that the new Mac mini (announced yesterday) is like the laptops in that the RAM is permanent and you won't be able to upgrade it later. If that is true you want to max it out now if you want it to be more future proof.
The old Mac mini has Intel HD Graphics 4000, which is good enough for Final Cut Pro. If your video editor is Adobe Premiere Pro, you want the new Mac mini announced yesterday because the 2.6GHz model has Intel Iris Graphics which will allow GPU acceleration in Premiere.
the downgrade to dual from quad CPU's doesn't look good. also taking it up to 16 gb of RAM is a must and really mandatory as it seems that its no longer user upgradable. if you think 8 gigs is enough now i guarantee in a year or two it won't because software is always wanting more power and resources. 8 gigs is a joke right now even though it will run but its like putting a 4 cylinder in a cadillac. my son used to use an 2009 i7 quad iMac and with 8 gigs of RAM he got lots of spinning beach balls with FCPX when using a moderate amount of plugins. going to 16 gigs of RAM made a huge difference.
if you would have only bought the quad i5 on the older ones then you don't get the "hyper threading" that only comes with the i7's. netting you 4 cores only. if you would get the quad i7 then you get "hyper threading" which nets you 8 cores...even though its not really equal to actual 8 cores but in many apps the extra virtual cores are used nicely to various processes.
so if you do buy a new one you really need to do the upgrade from the i5 to the i7 which has "hyper threading" that will net you 4 cores. if you only get the i5 then you really only have "2 cores" which is pathetic imo and would not be good for video.
i did notice that the new processors have "turbo boost". someone correct me if I'm wrong but i think the prior mac minis do not have turbo boost. if thats the case then the higher clock speed and turbo boost will add to a bit more performance with these lame dual core mac minis. anyway you stack it i can't see one of these new ones beating out the old one on apps that actually use CPU's a lot.

With respect to upgrading RAM, I saw that the manuals for the 2014 Mini were up, so I took a look. Neither the 2012 Quick Start Guide nor the 2014 Quick Start Guide explicitly say that RAM is upgradable or describe how to get at it. However, both have a photo showing the bottom of the Mini, complete with a round black panel.
In the 2012 Quick Start Guide, the panel has two finger-grip holes, and there is a caption saying "Removable panel". In the 2014 Quick Start Guide, the panel has no finger grips and there is no "Removable panel" caption.
For photo it will work, although I'd rather have an SSD than a good old spinning hard drive; for video it could work in a pinch but it might take some time, for instance I've used the Handbreak app on my old Mac Mini and it worked fine, but I'm sure newer PCs would go faster... Serious video editing probably requires a bit of a monster PC - Mac Pro and such.

A minilab is a small photographic developing and printing system or machine, as opposed to large centralized photo developing labs. Many retail stores use film or digital minilabs to provide on-site photo finishing services.
With the increase in popularity of digital photography, the demand for film development has decreased. This means that the larger labs capable of processing 30,000-40,000 films a day are going out of business, and more retailers are installing minilabs.
In Kodak and Agfa minilabs, films are processed using C41b chemistry and the paper is processed using RA-4. With these chemical processes, films can be ready for collection in as little as 20 minutes, depending on the machine capabilities and the operator.
A typical minilab consists of two machines, a film processor and a paper printer/processor. In some installations, these two components are integrated into a single machine. In addition, some digital minilabs are also equipped with photo-ordering kiosks.
Despite their small size, minilab machines may use chemical processing just like larger dedicated photo processing labs, using processes such as CP-49E or RA-4 for photographic paper processing, and C-41 for film processing. All necessary processing chemicals may arrive in a box (replenishment cartridge) containing enough bleach, developer and fixing agents to be mixed automatically for an estimated amount of paper, eliminating the need to manually handle and mix chemicals.[1][2] Minilab machines were used in stores to perform film processing and printing in a short period of time, usually less than one hour from start of film development to the end of printing, partly because it eliminated the need to send rolls of film and printed photos to and from a large central photo processing lab.
35 mm films are pulled, this means all of the film is extracted from its roll. This can be done manually or by using a small machine that essentially uses tape to pull the film leader and all of the film out of the cassette. This small machine may be integrated into the film processor. If so, rolls are inserted inside a chamber, slot side towards the inside of the machine pointing downwards at an angle of 45, the chamber is closed and the film inside the rolls is pulled into the processing mechanism. In cases when the end of the film cannot be removed or if the film is damaged, the film can be removed using a dark bag or a dark box. Before processing, a twin check number (a pair of stickers with a unique number) is manually put onto the film and the matching number onto the film processing envelope, so that after processing this film can be easily identified to the customers envelope. Films are spliced on the leader cards one or two at a time, to do this the end of the film is cut square, special chemical-resistant tape is used to attach the film to the leader card. The leader cards are then inserted into the film processor mechanism and are fed through the machine using sprockets in the card. The film goes through a developer, bleach, fix and stabilizer, then through a dryer. After the film is processed it is cut from the leader card and reunited with the processing envelope containing the customer details, and then from here the film goes forward for printing. Alternatively the film may be used immediately to expose silver halide photographic paper, shining a bright light through the film and into the paper using lenses for optical enlarging, which is then processed like film in a separate mechanism. Or the film may be digitally scanned using a CCD image sensor, corrected using software, and sent to a digital silver halide printer.
A minilab is typically a Roller Transport processor, where the film follows a serpentine path over many rollers. Each chemical processing step is done using a chemical immersion tank with replenishment to keep the chemicals fresh. Film advances down into the tank and then turns and rises up and out, then advances down into the next tank, and so forth. Chemical exposure timing is a combination of film advance speed and the physical length of the serpentine film path immersed in the fluid. The fluid in the tanks is usually agitated, filtered and warmed to 100 F (necessary for the C-41 process), and the fluid also needs periodic replacement. The Film processor also has a dryer, just like wet silver halide printers.[3]
A single minilab can be built to allow many different film widths in one device, from APS films to professional wide format films, using a flexible leader to pull the film through the mechanism. The leader is as wide as the widest possible format, and films attached to it are supported by guide rollers only. The leader may be gripped on each side between toothed drive belts following the same path as the film through the mechanism.
