Resolume Arena troubleshooting

Common Resolume Arena errors & problems

What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.

• Custom font not appearing/rendering in Text Animator source

  Likely cause: Resolume's text renderer only picks up fonts registered system-wide and doesn't reliably support variable-weight font files.

• MIDI controller stopped working / behaves wrongly in Resolume after a Windows 11 update (MIDI 2.0)

  Likely cause: Swapping to the USBMidi2-ACX driver restores class-compliant behaviour for the controller under the new Windows MIDI stack.

• Black output / no signal on a laptop (NVIDIA Optimus)

  Likely cause: Optimus laptops route the external display through a different GPU path; a wrong driver profile matched to Arena.exe drops FPS, and a mis-assigned GPU can collapse the output surface.

• Short random flashes with blocky artifacts on output (NVIDIA graphics card)

  Likely cause: The custom driver profile Resolume installs can interact badly with some cards/drivers; maximum-performance power mode and triple buffering stabilise frame delivery.

• Third-party/custom FFGL effects missing after moving to an Apple Silicon Mac (or built-in effects missing on a fresh Windows PC, v6.1.3 era)

  Likely cause: FFGL plugins are native binaries; architecture must match the host app, and Rosetta runs Resolume as Intel so Intel plugins load.

• Live-stream the Arena output (to OBS / online)

  Likely cause: Offloading encoding to OBS keeps Arena free for real-time mixing; NDI carries the program feed between apps/machines with minimal latency.

  Step-by-step fixGet the fix →

• OUT OF MEMORY error / very high VRAM on a simple composition

  Likely cause: Every loaded texture consumes VRAM; oversized comps, H.264 decode buffers, and a leaking OSC loop exhaust the GPU and Arena aborts.

• Sync Arena playback to house SMPTE timecode

  Likely cause: Locking clips to LTC makes Arena a slave to the master show timeline, so video hits stay frame-aligned with lighting/audio across the whole run.

  Step-by-step fixGet the fix →

• DXV clip alpha/transparency not showing (renders opaque)

  Likely cause: DXV stores alpha only when rendered at full bit depth with the alpha-enabled codec variant; a reduced-depth export bakes a black background instead.

  Step-by-step fixGet the fix →

• Blend two or more overlapping projectors into one seamless image

  Likely cause: Overlapping projectors double the brightness in the seam; the progressive fade (soft edge) cross-dissolves the overlap so total light stays even and the join disappears.

  Step-by-step fixGet the fix →

• Clips show a red X / media is missing after moving files

  Likely cause: The composition stores file paths, not the media itself.

  Step-by-step fixGet the fix →

• Control Arena from a lighting console (DMX/Art-Net)

  Likely cause: Exposing Arena parameters as DMX fixtures lets the LD run video from the same desk as lighting, fader-for-fader, without a separate operator.
