Deckboy v0.99.419 — a guided tour; the warp editor shows the output being warped; steadier ASIO, scopes, crossfades and refresh rates

Re-released on 24 October 2026 with the guided tour. If you downloaded 0.99.419 on
23 October, please download it again: that build does not include the tour, and because the
version number is the same, its update check will not offer this one.

Learn the basics

• New: a guided tour, taught by Dr. Pixel and Professor Video. In nine steps it covers turning the
  output on, importing a clip, TAKE, lining up the next cue, a one-second crossfade, BLACK and
  saving. Each step dims the window except the control it is about, and moves on only once that
  control has really been used. SHOW ME does a step for you, SKIP passes it, and EXIT or Esc
  leaves. Leave half way and the next run starts at the same step.
• It runs in a practice show (tutorial-practice.deckboy in Deckboy's settings folder). Your own
  show is saved first and reopened at the end, with its outputs and BLACK put back as they were.
• Start it from the startup screen (LEARN THE BASICS, or L) or from MENU → LEARN THE BASICS.
• Remote control: TUTORIAL [START|SHOWME|SKIP|EXIT|STATUS], and STARTUP SHOW to bring up the
  startup screen.

Warp

• Fixed: with two window outputs showing the same playlist, warping the second one in the WARP
  editor warped only the output; the programme monitor kept showing the first output, flat, with
  the corner handles moving over it. While the editor is open, the monitor now shows the output
  being warped.

ASIO

• Fixed a rare crash on ASIO output: if the audio driver stalled for more than half a second just
  as a cue's sound left the mix, Deckboy could read memory it had already freed. A cue's sound is
  now kept until the driver has certainly finished with it.

Transitions

• Fixed: changing a playlist's volume during a transition (VOLUME 0, a volume fade, the
  playlist fader) changed only the incoming cue; the cue on its way out kept its old level until
  its fade ended, about 1.2 s after VOLUME 0 in a 2-second crossfade. It now follows straight
  away, and so do the playlist's monitor and room mutes.

Scopes

• Fixed: with a 24, 25 or 30 fps clip on a 60 Hz output, the scopes measured only about one
  picture in four, not every picture as 0.99.418 promised. They now measure each new picture:
  measured 24.6 a second for a 25 fps clip and 23.7 for 23.976 on a 60 Hz output.

Outputs

• Fixed: an output set to 30 Hz (or 24) could switch its screen to 29.97 Hz or 59.94 Hz (or
  23.976 / 47.952), which drops a frame about every 33 seconds, and gave no warning. A set rate
  now takes only a mode of the same kind: 30 takes 30 or 60, 29.97 takes 29.97 or 59.94.

Moire

• Fixed: an oscillator that had been set up and then switched off lost its settings (rate, depth,
  shape, drawn curve) when the show was saved with every oscillator off, so switching it back on
  gave a different look. This also applies to the oscillators on a cue's size, position, rotation
  and crop.
• Fixed: a Moire oscillator ran one frame behind a picture effect's oscillator set to the same
  rate, so the two did not switch together.

Swirl and Fireside

• Fixed: on a tall, narrow output (such as 480x1920 or 1080x3840) a Swirl or Fireside came out
  the wrong shape, with bars or a stretch. Their reduced drawing size now keeps the output's
  proportions.

Stream Deck	Deckboy-1.0.0.streamDeckPlugin	Double-click it.
Bitfocus Companion	Deckboy-companion-module-1.0.5.zip	Unzip it somewhere permanent, then point Companion's developer modules path at the folder containing it. INSTALL.txt inside has the three steps.

First run

Deckboy is free software and is not code-signed, so the OS does not recognise the publisher. One time only:

• macOS — if it says the app is damaged: xattr -dr com.apple.quarantine /Applications/Deckboy.app
• Windows — SmartScreen may appear: More info → Run anyway

---

Deckboy is free, open-source cue-based media playback and show control for live video — clips, slides and live sources on one cue list, out to a screen, NDI, SRT or Blackmagic SDI, with a stream and a recording running at the same time and presenter view on its own display, driven from a Stream Deck, Bitfocus Companion, OSC, MIDI or LTC timecode.
