VPR

The Vidding Photosensitivity Relay is meant to serve as a consistent system for denoting photosenstivy triggers in fan-made videos. This is designed to be a community-based collaboration.

Adaptations for Events

Adaptations for Events

It is important that the relays are video-specific. Photosensitive people are well aware of general risks for video watching, and a boilerplate advisory for the entire show does not help these viewers.

  • Award ceremonies, contests, convention viewings, etc., can help accommodate photosensitive individuals in an audience by using the relays on title cards.
  • Photosensitive risks can be displayed alongside other content warnings, or delineated with a header such as VPR or Potential photosensitive risks
  • Short VPR may be used when listing all risks is not possible
  • During on-demand showings or in contexts where the identity of people with photosensitivities are known, digital or physical handouts with the VPRs for all videos may be given ahead of the showing(s).
 


VPR Examples

While it is not required, it is recommended to give the short VPR variant directly followed by the standard/full VPR.

Super Happy Fluffy Jumping Times

VPR: Motion Entirely comprised of characters jumping rope. Motions and patterns related to that are in every scene. Some zoom transitions.

0:10 double wipe transition
0:31 - 0:33 textured movement/distortion

An Eggcellent Adventure

VPR: motion, peripheral, minor red

Mixed media, but primarily 3D/CG animation. Transitions are cuts and some slow quick zooms with rare fades. Focuses on an uncooked egg, so most scenes include clear liquid motion and yellow yolk motion. Some soft light effects that for the most part should be predictable. Occasional peripheral effects, such as speedlines.

Stand outs:
Starts with dark blue scene
0:13 spotlight
0:31 bright + peripheral
0:53 - 0:56 fast moving grid bg
1:14 - 1:15 red + moving peripheral
1:19 - 1:27 white dip; black vignettes; animation change; lower framerate; 2d to 3d rain transition

Worth

VPR: Peripheral, overlays, minor motion, minor quick cuts, minor black cuts
CW: child abuse? blood

Video is letterboxed. Generally slow video with natural peripheral framing and soft but prominent light rays throughout, but mostly concentrated in the beginning. There is one part with quick cuts and a few rare parts with black cuts. Isolated incidents with heavy light leaks, one section with natural particles (falling flower petals, etc). Rare isolated incidents of tunnel motion. Times of note:
0:00 - 0:08 Video begins with tunnel motion
0:38 white tunnel motion
1:03 circles + tunnel motion
1:35 - 1:36 circular pattern
1:38 - 1:57 most particles
1:58 - 1:59 moving peripheral bottom right corner
2:14 circles

Purrgatory

VPR: All Semi-frequent flashing from lightning/lighting randomly throughout. First half of video uses a blurred vignette with color field offset. There are some sections of video with lower framerate than others. Some natural peripheral framing throughout, rare but isolated peripheral effects. Two isolated sections of red scenes. Transitions vary between cuts, blurs, and black dips.

0:05 video starts with characters near a mirror with a distinct frame
0:14 - 0:27 blur, peripheral, color offset, some twinkling and light flashing
0:47 - 0:49 peripheral + moving silhouette
1:06 - 1:24 low framerate
1:11 - 1:12 quick cuts
2:06 - 2:07 peripheral bidirectional moving black bars
2:19 - 2:26 red
2:33 - 2:38 red

Cyberpunk Resurrections

VPR: Major Strobes, major flashing & flickering, major peripheral, neon green, red/pink, blue, motion, minor red

Video has several glitch effects, hard lighting, flashing, quick cuts, flickering particles & patterns, and peripheral moving text/glitches. Neon green, red/pink, and blue are dominant throughout. Several natural strobes (e.g. trains) and some light strobes.

2:35 - end INTENSE LIGHT STROBES, COLORS, & PERIPHERAL

 


Introduction to Writing VPRs

TL;DR:
Briefly describe what visually happens in the video. Use timestamps if risk factors are isolated to one section.
Make this visible somewhere before the video starts playing.

A VPR is a balance between describing what happens visually in the video with timestamps while also not being too detailed. Generally one paragraph is all that is needed. If a video is overflowing with risk factors, there is no need to list timestamps for them all unless they are isolated to one section of the video.

The relay should be visible or easily found before the video begins to play. Always put the VPR in the title, filename, description, and/or hyperlink text to the video. If putting the VPR inside these is not possible, place them directly next to those elements.

When possible, identify what the exact risk factors of the video are (not just the categories). In the case of Youtube, this is most easily done by placing it in the video’s description area. If a text VPR is impossible, or an additional VPR notice is desired, place the VPR inside the video itself as a title card or overlay before any risk factors play.

If you include the VPR as part of the video, it should:

  • be at the beginning
  • on screen for at least 2 seconds
  • not contain any moving elements

The most common method of making a video-based VPR is white text on a black background.

Order of Elements

When summarizing a video’s risk factors, they should be ordered from most likely to harm to least.

While this can vary in the context of your particular audience, most often this means the risks which happen the most frequently and/or with the most intensity come first, and are listed in this order until the last element, which has the least intensity and/or frequency.

When listing timestamps, the times should be listed chronologically.

 


Use of the Words Major and Minor

Intensity

These words are optional in the standard/full VPR. When used, “Major” refers to above-average intensity of risk factors and “minor” refers to below average intensity.

As an example, if the video has blurs throughout, but they are all no stronger than a radius of ~2, this could be called “minor blur” as they are weak compared to most blurs we normally see in fan vids.

If the vid has blurs and all of them have a radius of 100 or greater, that is much stronger than we’re used to seeing in videos, and could be referred to as “major blur” if desired.

Frequency

In shorter VPR variants, “major” and “minor” almost always refer to how often the risks occur.

For example, if a fan vid has no risk factors except for blurs from 0:25 to 0:30, shorter relays which do not use timestamps would instead use “minor blurs” since the blurs are only present in a small section of the video.

 


Videos Without Any Risks

There will always be some risk associated with watching videos for photosensitive individuals. If you believe a video does not have any risk factors, you can use VPR: No Known.

It is important to still use VPR in these cases to show that photosensitivities were considered. Otherwise, it may come across as a normal (possibly risky) link to a photosensitive individual.

 


VPR Variants

Please use the full VPR whenever practical. However, we realize this is not always possible. Therefore, a few variants have been developed.

Short VPR

  • Only lists categories instead of specific risks and rarely gives timestamps.
  • Typically used before the full relay as a summary.
  • If there is a risk factor that only occurs in one part of the video (e.g. blurs only from 0:25 to 0:30):
    • With timestamps:
      VPR: blurs 0:25 - 0:30
    • Without timestamps:
      VPR: blurs 0:25 - 0:30 becomes VPR: minor blurs
      The singular risk is “minor” because it is only a minor part of the video.

Tiny VPR

This version of the relay uses letters and symbols and was constructed specifically for filenames.
If space is an issue, please use the short VPR in public-facing relays if at all possible.

The tiny variant starts with V_ (uppercase “V” followed by an underscore) and uses the letters corresponding to each risk category to form the relay.

Average risks are indicated by uppercase letters and minor risks use lowercase. Major risks have a + (plus sign) prefix before the letter.
If increased legibility between the letters is desired, they may be separated by an _ (underscore).
Example:

Short VPR: major flashing, major strobes, high contrast, minor peripheral
in Tiny VPR, would become:
V_+F+SCp or V_+F_+S_C_p
