Ideal price for 16mm films?

What would be an ideal price for 16mm films that have a running time for more than 20 minutes. Also, how long is 100ft of film in time for 16mm. Thanks in advanced!

 

reel size metre feet .........approximate recording time
7cm(3inch) 23m 50ft ..........3～5min
13cm(5inch） 90m 200ft .........20min
16cm(6inch） 120m 300ft ..........30min
18cm(7inch） 180m 400ft......... 40min

I believe this is correct

 

Your main concern when buying needs to be condition. Old film degrades. Always check for a vinegar smell. If any, avoid. Subject matter is secondary to condition. Most old film is on its way to self destruction.

 

I don't think that's correct to be honest.

 

?

Can you be more specific? looks like komokwa gave very specific information - can you explain what is wrong with it?

 

try this then.....

• 122 m (400 feet) = about 11 minutes at 24 frame/s

plus...be aware of..........

Over time, the cyan, magenta and yellow dyes that form the image in color 16 mm film inevitably fade. The rate of deterioration depends on storage conditions and the film type. In the case of Kodachrome amateur and documentary films and Technicolor IB (imbibition process) color prints, the dyes are so stable and the deterioration so slow that even prints now over 70 years old typically show no obvious problems.

Unfortunately, dyes in the far more common Eastmancolor print film and similar products from other manufacturers are notoriously unstable. Prior to the introduction of a longer-lasting "low fade" type in 1979, Eastmancolor prints routinely suffered from easily seen color shift and fading within ten years. The dyes degrade at different rates, with magenta being the longest-lasting, eventually resulting in a pale reddish image with little if any other color discernible.[9]

 

I may have used the times for 8mm by mistake..........
but thanks for having my back !!!

 

A 16mm frame is about half an inch high. 25 frams per second is about 1 foot of film per second. It would seem to me you'd need 600ft of film to run 10 minutes.

 

Well I'm no film buff...or math wiz.....but this guy seems to have it down....

The difference lies in frames per second...

 

You ask about price, and the condition issue has been covered. The subject matter would count too, obviously. A lot of 16mm has been converted to digital and uploaded to you-tube, so check title by searching you-tube. I'd think the demand for films already on you-tube, Vimeo, etc. would be very low, but I have no experience there.

 

Ok thank you all! Does anyone know where I would find a bunch of films besides eBay?

 

Depends on what films you want. If you just want the plastic strips for an art project, is easier. My brother has loads of that stuff in CA depending on your needs.

 

I'm looking for films I can watch. Preferably longer films.
