Screenshot minimum size
The recommended screenshot size is still given as 320x200, but given the number of releases that include the border either to show border effects or just to give the central area the same context as other releases, the few remaining new productions that use 320x200 now convey quite a misleading impression.
Could we bump the recommended (& minimum upload?) size to 384x272, and perhaps set a minimum size for the IMG element on the summary view so that old uploads are padded browser-side? |

Quote: Quoting hedningHow hard would it be to implement correct aspect NTSC screenshots when making screenshots in Vice? About as hard as implementing screenshots with PAL filter. =)
So they just didn't implement it, then, because reasons, I guess. Sad. |

The screenshot function in VICE is from ancient times, its a seperate render function, it doesnt know about "aspect ratio" or "CRT emulation" at all.
And of course PAL screenshots do not have correct aspect ratio either - only the error is less. And limiting the size to an exact pixel size is silly at best - the dimensions VICE uses are not set in stone, and someone using "full border" gets an equally valid - but different - output too.
edit: rewriting the screenshot feature is on the list of things todo after 3.5 release. at this point various new dimensions of screenshots will emerge. |

To clarify, my comments above were regarding CSDB's limitation on screenshot sizes - I uploaded several that were (I'm assuming) culled by the system and they were directly from VICE. Since VICE is the de-facto standard for emulation, it doesn't seem unreasonable to me to have the site accept whatever it generates. |

Yeah, someone recently turned the "should" requirement into a "must" in his head and is on a mission. Doesn't make sense to me either.

to make that more clear: the screenshots currently use a pixel aspect ratio of 1:1. this is wrong in either case - the correct pixel ratio would be 0,75:1 for NTSC and 0,936:1 for PAL. ie a PAL screenshot should be 359 pixel wide instead of 384, NTSC should be 288 respectively. And even that is wrong, because the resulting image should be 4:3. And of course none of this would work with "no scaling" or "no filters" (you'd at least want double size or it will look terrible). |

Geez, nit pickers!
I'm already happy when there's a screenshot in the first place (although most releases have them by now).
I'd rather have people use a proper pallet, instead of those bleeding eyes causing harsh neon-ish colours. |

Indeed :) It would also make a lot of sense to relax that rule to "must include full screen including borders" - as the actual pixel size doesnt really matter at all. |

It's even worse for the C128 VDC releases. Exporting from VICE gives you 856x288 quadratic pixels, which means the image is 200% stretched in X.
Not that I would expect many releases for that mode though... |

Fair point about NTSC - and yes, it'd make sense to me to drop the minimum to 384x247 on that count.
I'm just (not) looking forward to the day I get around to releasing something that relies on chroma noise, and can't upload an accurate screenshot ;) |
