Screencap subtypes

If we had subtypes for iTunes, Broadcast, DVD and HD captures, that would allow us to keep track of image quality and upgrade screencaps as better soure material becomes available. --Peter Farago 11:30, 14 April 2006 (CDT)

Agreed. Will implement. -- Joe Beaudoin ^{So say we all - Donate} 11:36, 14 April 2006 (CDT)

I don't think that {{HD-screencap}} is adequate for both HDTV and DVD sources. I'd suggest the following Hierarchy (vertical resolution in parentheses):

iTunes (176 lines, widescreen)
NTSC Broadcast (480 lines, letterboxed to 360 lines)
PAL Broadcast (576 lines, letterboxed to 432 lines)
NTSC DVD (480 lines, anamorphic)
PAL DVD (576 lines, anamorphic)
HDTV Broadcast

720 lines, widescreen
1080 lines, widescreen

HD DVD/Blu-Ray

1080 lines, widescreen

I'll go ahead and implement this with your approval. --Peter Farago 16:18, 14 April 2006 (CDT)

Frack! --Talos 16:18, 14 April 2006 (CDT)

More thoughts before we get underway:

We need a field to specify whether the image has been cropped from its original dimensions (as most of the one's I've uploaded have been). This shouldn't be too hard.
Timestamps would also be good, so that later users can upload higher-rez versions more efficiently. Obviously it would be too onerous to go back and do this for every image in the database, but it should be available and encouraged for future uploads.
It would be very nice if we could mark the episode source of each image and provide release dates for higher quality versions (scheduled HDTV airtimes, NTSC and PAL DVD release dates). We could do this by using the template to mark the episode of each image as a new category (something like [[Category:33 (Images)]]. We could then keep the Category page updated with availability information, perhaps synchronizing DVD release dates for half-seasons using a template. --Peter Farago 16:29, 14 April 2006 (CDT)

Template Prototype

A complete image tag should look something like this:

	This is a NTSC DVD screen capture from the episode "33".
	NTSC DVD screen captures are in anamorphic widescreen, with a native resolution of 480 x 720.
	The horizontal dimension of this image has been scaled to 834 pixels for aspect ratio purposes.
	The timestamp of this capture is MM:SS.FF
	This image has been cropped from its original dimensions.
	Higher quality versions of this image will be available on the following dates: PAL DVD: [release date] HD Broadcast: [broadcast date] HD-DVD: [release date]

Notes:

The message: "The horizontal dimension of this image has been scaled to 834 pixels for aspect ratio purposes." is relevant for current-generation DVD sources, and should be specified by a boolean field. If the field is left blank in the template, the above message shove be replaced with "The horizontal dimension of this image must be scaled to 834 pixels for aspect ratio purposes."
- For PAL DVD, that would naturally be 1024 pixels instead.
- If the field is left blank, the image should be added to a category, something like "Category:Images with incorrect aspect ratio".
The message "This image has been cropped from its original dimensions." should also be specified by a boolean, and naturally should be omitted if the image has not been cropped.
Release dates for higher-resolution images can be kept in sync via a series of templates, so these templates need only refer to {{ {{{episode}}}_PAL_release_date }}, for example.
Images should be tagged with the following categories:
1. Category:Screenshot
2. Category:33 (Screenshots)
3. Category:33 (NTSC DVD Screenshots)
Each of these should be a subcategory of the one listed above, to aid in sorting.

I know almost enough to implement this by myself, but I'll need some help with the aspect ratio if/then/else bit. I'm confidant that this can be a reasonably automated and efficient system. It doubt it will be as hard as it looks. --Peter Farago 17:00, 14 April 2006 (CDT)

I don't think that the clever CSS hack used to implement hiddenstructures will work the other way around. I remember we eliminated the if_defined templates a while ago, and were glad to be rid of them, but do you think it would be justified to import Wikipedia:Template:Unless defined for the aspect ratio business? --Peter Farago 18:18, 14 April 2006 (CDT)

Wiki code has a bad "if" time. They are working on a policy to fix this problem. On another note, I think your ideas are sound. --Shane ^{(T - C - E)} 22:03, 14 April 2006 (CDT)

How about Template:Qif? -- Joe Beaudoin ^{So say we all - Donate} 22:28, 14 April 2006 (CDT)

How does it work? --Peter Farago 02:41, 15 April 2006 (CDT)

Nevermind, I found it on Wikipedia. --Peter Farago 02:12, 16 April 2006 (CDT)

Well, mostly done. I've created five new tags:

And a series of broadcast/release date templates to help keep track of quality updates. I'll clean up the rest of this tomorrow - fill the category tags, create some miniseries release templates, and the NTSC broadcast templates so that we can round everything out with a new iTunes tag. --Peter Farago 05:12, 16 April 2006 (CDT)

I think things are good to go. --Peter Farago 15:23, 16 April 2006 (CDT)
