There should be a link to JFK in the article. I mean Zapruder's is the most famous 8mm footage ever. —The preceding unsigned comment was added by 82.131.210.162 (talk) 16:52, 19 February 2007 (UTC).[reply]

````I am requesting that all the 8mm external links please be put back. thanks in advance. ````

In regard to Zapruder, such link would be inappropriate to this article, which is about the nature and definition of the film format. In other words, Zapruder is irrelevant to this material. — Preceding unsigned comment added by PastReflections (talk • contribs) 21:14, 22 September 2019 (UTC)[reply]

8mm film into digital

How do you convert 8mm film into digital video to use on your computer to upload to a website or to make a dvd with the video? i think we should add the how to to this article as well —Preceding unsigned comment added by Pauldonald86 (talk • contribs) 06:26, 9 October 2007 (UTC)[reply]

Telecine. Girolamo Savonarola 06:40, 9 October 2007 (UTC)[reply]

I thought the same thing when I read the article. The term of transferring film to video is called "telecine." This ought to be included in the article along with a link the wiki on telecine http://en.wikipedia.org/wiki/Telecine. — Preceding unsigned comment added by 97.122.107.29 (talk) 04:30, 6 March 2010 (UTC)[reply]

Re:solution

If we think in digital terms, what is the maximum physical resolution of a high-quality Super8 color or b/w negative film frame? 320x240 pixel or maybe 512x384? I guess if you scan at too large resolution, like 2048x1536 you only get "empty" zoom, but no more details revealed. I heard 35mm ISO-100 color photo negative film stock has about 300dpi max. resolution due to limits imposed by silver-iodide grain size. 91.83.0.204 (talk) 18:06, 13 April 2008 (UTC)[reply]

double super 8

some mention of double super 8 is warranted. —Preceding unsigned comment added by 68.32.157.242 (talk) 17:03, 2 February 2011 (UTC)[reply]

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on 8 mm film. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

Article excerpt mention in Hitman 2

A cutscene from the game used an excerpt from the article, fyi. Can anyone bring this to the attention of those in the WP:VG and Film wikiprojects? I don't own the game yet, but apparently this has been copy-pasted without attribution based on what was listed on MobyGames. Thought someone might notify IOI about it to rectify things as this is a licensing violation. Blake Gripling (talk) 13:33, 4 January 2019 (UTC)[reply]

I did notify David Bateson about the issue on his Facebook fan page though. He says he'll talk with the writers about it though idk if anything has been done. Blake Gripling (talk) 02:49, 21 October 2019 (UTC)[reply]

sound to picture separation

"Sound to picture separation" & "image-sound separation" are both mentioned in this article, as well as in related articles, but it is never explained, and pasting the phrases into Google does not quickly yield an explanation. Is there an existing article or external reference which discusses it that could be linked to? If not, then it needs to be explained here. DKEdwards (talk) 05:25, 5 August 2019 (UTC)[reply]

It isn't a technical term of art; it has to be divined from the preceding context and they've left out some helpful words:

"The only part of the film wide enough to accept such a magnetic stripe was the area between the edge and the perforations. A much narrower [magnetic] stripe was sometimes added to the opposite edge so that the film piled up evenly on the spool, but was never used for sound. The sound[-stripe] to picture[-framing area] [distance-]separation was the same dimensionally as 16 mm film and as that format is 28 frames",

ie: 'The physical distance between the sound-stripe and the frame... 'stripe', if you will, was the same distance as that in 16 mm film...' JohndanR (talk) 00:56, 29 November 2020 (UTC)[reply]

Correction to description

The description incorrectly implies that standard-8 and double-8 are different. Double-8 is standard-8 is regular 8: all the same. Standard-8 begins as a 16mm-wide film, with sprocketing slightly different from 16mm. After it has been run through the camera twice to expose both sides of the roll, it is sliced lengthwise and the two ends spliced together to make a strip of 8mm film twice as long as original the camera roll. The author may have been thinking of single-8 as the alternative. The format is the same, but it went through the camera as a single 8mm-width of film. Most single-8 cameras were unsuccessful, but the very inexpensive 8mm Univex line was highly popular and accounted for the great majority of the sales of single-8 film for a number of years. Bell & Howell and Revere both produced single-8 cameras but neither sold well so both are very hard to find now. PastReflections (talk) 21:14, 22 September 2019 (UTC)[reply]

I have combined the Standard and Double 8 sections. There is more detail at Standard 8 mm film. Someone had edited that page to say these are not the same thing. We don't have many source citations, but the few we do have verify that these are the same thing. GA-RT-22 (talk) 19:56, 19 September 2020 (UTC)[reply]

projectors

As far as I know, most Super-8 projectors will also projects Standard-8. Maybe a switch to change the pull-down sprocket setting. Or is it not most? In any case, ones that do need to be able to accept both kinds of reels. Gah4 (talk) 00:19, 22 February 2022 (UTC)[reply]

It may have been true when super 8 first appeared, but super 8 only projectors quickly became the norm. Standard 8/Super 8 projectors were mechanically complicated as the gates were of different formats as well as the sprocket format. The most successful projectors were those that required a physical change of the affected parts rather than a turn of a switch. It was possible to construct a dual sprocket with the smaller super 8 sprockets mounted on top of the larger standard 8, but only because the pitch of standard 8 (80 per foot) was less than super 8 (72 per foot). However, this change of pitch did complicate the pull down mechanism. Film editors, on the other hand, were almost universally dual format only requiring a dual sprocket to rotate the prism shutter and few bothered to mask off the surplus area around the visible frame on standard 8.

Sound projectors had the added complication that the picture/sound separation of the two formats was very different (not to mention that the sound track was on opposite sides of the film). Standard 8 was 56 frames versus 18 frames for super 8 (for magnetic sound track). 81.154.179.214 (talk) 14:37, 23 February 2022 (UTC)[reply]

OK, I might be remembering the early ones, and also editors. I actually have a Super 8 projector, bought from Goodwill for a good reason, but haven't looked at it that closely. I do remember the reel mounts that would take either reel, though. Gah4 (talk) 22:00, 23 February 2022 (UTC)[reply]

color balance

Traditionally, 8mm films were Type A tungsten balanced for, I believe 3400K photofloods. In daylight, there was an orange filter to correct for daylight balance. The allowed for more sensitivity in the dimmer artificial light, though that might have been less common. Should the article mention this? Gah4 (talk) 22:04, 23 February 2022 (UTC)[reply]

It would be a good addition. When super 8 was conceived by Kodak, it was intended that only type A film would be available and a conversion filter would be included in every camera. The intention was to allow mixed filming in daylight and artificial light. It was convenient that the Kodachrome II daylight film was 25 ASA and the type A was 40 ASA. The conversion filter to allow type A to film in daylight just happened to reduce the effective ASA to 25 (also the colour rendering in daylight was better than with daylight film). The type A super 8 cartridge has a notch to indicate that type A film is loaded but most early cameras ignored it. Kodak later released type G Ektachrome film which was daylight balanced but worked reasonably well (but not perfectly) in artificial light. 81.154.179.214 (talk) 13:01, 24 February 2022 (UTC)[reply]
