Mastering Cyber-D’s Image Sequence Viewer: Tips & Shortcuts
Overview
Cyber-D’s Image Sequence Viewer is a tool for loading, reviewing, and annotating ordered image frames (e.g., time-lapse, rendered sequences, or frame-by-frame VFX). This guide focuses on practical tips and shortcuts to speed navigation, improve inspection accuracy, and streamline export/annotation workflows.
Navigation & Playback
- Keyboard play/pause: Use the spacebar to toggle playback — faster than clicking UI buttons.
- Frame step: Left/Right arrows move one frame; Shift + Left/Right jumps 10 frames (useful for long sequences).
- Looping: Enable loop mode for continuous review; pair with a short play speed to inspect motion artifacts.
- Playback speed control: Reduce speed to 0.5x or 0.25x when checking subtle changes between frames.
Loading & File Handling
- Sequential import: Drag the folder containing numerically named frames to auto-load as a sequence.
- Frame padding recognition: Ensure filenames use consistent padding (e.g., 0001, 0002) — viewer detects sequence ranges automatically.
- Proxy usage for high-res: Create and load lower-resolution proxies when working with very large images to keep playback smooth.
Inspection & Comparison
- Onion-skin / overlay mode: Use onion-skin to compare adjacent frames and detect jitter or flicker.
- Difference/blend modes: Toggle difference or blend blending to highlight pixel changes between frames.
- Split-view: Use side-by-side comparison for original vs. graded frames.
- Zoom shortcuts: Ctrl/Cmd + mouse wheel or double-click to zoom to 100% for pixel-level inspection. Use fit-to-window for context.
Annotation & Notes
- Frame tagging: Tag problematic frames (e.g., “artifact”, “needs-grade”)—export tags as a list for review.
- Frame-range notes: Attach notes to ranges (e.g., frames 120–145) to record sequence-level issues.
- Hotkeys for markers: Assign hotkeys to common markers to speed up QA passes.
Color & Exposure Tools
- Temporary LUTs: Load a LUT to preview intended color grading without altering source frames.
- False-color/exposure overlay: Use false-color to spot clipped highlights or crushed shadows quickly.
- Color-sampling: Use an eyedropper and histogram overlay to track problematic exposure shifts across frames.
Export & Delivery
- Export selected frames: Export only flagged frames (or ranges) to reduce review package size.
- Create review movie: Export a compressed review file with burn-in frame numbers and markers visible.
- Embed metadata: Include frame tags and notes in sidecar files (e.g., JSON or XML) for downstream tools.
Performance Tips
- GPU acceleration: Enable GPU decoding if available for smoother playback of large formats.
- Cache frequently used sequences: Use the viewer’s cache feature for repeat passes on the same shots.
- Close unused panels: Hide side panels (scopes, annotations) when you need maximum playback performance.
Troubleshooting Quick-fixes
- Missing frames: Rename frames to consistent padding and reload the sequence.
- Playback stutter: Switch to proxies, lower playback resolution, or enable GPU decoding.
- Color inconsistency: Confirm the viewer’s color-management profile matches source color space.
Suggested Hotkeys (assumes common defaults)
- Space — Play/Pause
- Left/Right — Step frame
- Shift + Left/Right — Jump 10 frames
- I / O — Set in/out for range export
- M — Toggle marker on current frame
- Ctrl/Cmd + S — Save session or annotations
