Common setup and operation answers for P-MIX Studio, collected for real-world event use.
Video: MP4, MOV, M4V, MKV
Images: PNG, JPG, JPEG, WEBP, BMP (single images are auto-compressed to cache if over ~10MB)
Audio: MP3, WAV, AAC, FLAC, M4A
Documents: PDF (treated as PPT layer with page flip; one PDF per scene)
PPT/PPTX are not supported and require a separate plugin.
Click the 「+」/ Add Scene button in the scene list panel. A new scene is appended with a default name like "Scene N".
Use the Reorder Scenes dialog: open it from the scene list area (menu or button), assign each scene a unique position 1 through N, then confirm. You can also use Left/Right arrow keys to change the selected scene (sent to Preview).
Edit: Right‑click a scene card → "Rename Scene", or click the scene name to edit in place.
Delete: Select the scene and click 「−」/ Remove Scene, or right‑click the card → "Remove Scene".
Click the scene name on the card to edit, or right‑click the scene → "Rename Scene" and enter the new name in the dialog.
Use the W (width) and H (height) sliders at the bottom of the main window in the scene area. W range is about 120–360, H about 50–280.
Press 1–9 to cut the corresponding scene to Program. Select a scene and press Enter or C to perform Cut. Use Left/Right arrows to change the selected scene (send to Preview). All shortcuts can be customized in Edit → Hotkey Editor.
Play/Pause: Space
Stop: S
Program window reflects playback; use Space in Preview after selecting a scene to preview that scene.
CUT: Hard cut, no transition. Shortcuts Enter or C.
MIX (AUTO): Auto transition (cross‑dissolve). Click MIX or press A/M to select the mode, then Enter to execute (default ~1 s). If the Transition panel is visible, set type to FADE and adjust Duration (ms) (about 100–5000 ms) for the mix length.
FTB (Fade to Black): Fade to black. B or F toggles FTB on/off.
Global default: In Settings, under "Playback Defaults", enable "All Video Fade Out On" and "All Audio Fade Out On" so that in the last ~1 second of playback all scenes get video fade‑out and audio fade.
Per‑scene override: Right‑click a scene card and enable "Video Fade Out Off" or "Audio Fade Out Off" to disable fade for that scene only.
Loop: Right‑click scene card → "Loop", or in the Layer panel right‑click a layer → "Enable Loop". Playback restarts from the beginning when it ends.
End‑to‑scene: Scene right‑click → "Auto To 1", "Auto To 2", etc. When playback ends, the specified scene is cut to and played. Mutually exclusive with Loop; enabling Loop clears End To.
Auto Next: When enabled, after playback ends the next scene is cut to automatically. Mutually exclusive with Loop and End To.
Within each scene, layers are ordered by the list: list order = draw order (top of list = top layer, drawn last). Typically put video on lower layers and images/PDF on upper layers. In the Layer panel you can drag or use Move Up / Move Down to reorder; lower layers are drawn first, upper layers on top.
Save with media: Cmd+S or File → "Save with file" — saves the project as .pmix (JSON) and copies referenced media into an _media folder next to the project file, using relative paths so the project is portable.
Save project only (PJ only): File → "Save PJ only" — saves only project data (scenes, settings); media paths are written as relative if they are already under the project directory.
Note: When moving to another machine, use "Save with file" and copy the whole project folder including _media. If media is missing on open, ensure paths are valid or replace files manually.
Default shortcuts (all editable in Edit → Hotkey Editor):
Left: Media browser — drag or select video/image/audio/PDF to add as layers to the current scene.
Center‑left: Scene list — select a card to send to Preview; double‑click or Enter to cut to Program.
Center: Preview and Program windows; below them, CUT / MIX / FTB and playback controls.
Right: Layer panel (order, visibility, loop per layer), Mixer, transition duration, etc. Bottom sliders adjust scene card W and H.
Menus: File (New/Open/Save), Edit (Hotkey Editor), View (Mixer, etc.), Settings, Help.
