GBDeflickerApp — Fix Flicker Fast for Pro Time-Lapses
GBDeflickerApp is a focused utility for removing exposure and brightness flicker from time-lapse sequences, optimized for speed and preserving detail. It targets common flicker sources like automatic exposure shifts, rolling shutter variations, and inconsistent lighting during sunrise/sunset sequences.
Key features
- Fast batch processing: Process large image sequences or video exports with minimal configuration.
- Adaptive smoothing algorithm: Detects frame-by-frame luminance jumps and applies temporal smoothing while retaining edge and texture detail.
- Per-frame diagnostics: Visualize detected flicker curves and per-frame gain adjustments.
- Multi-format support: Input sequences (JPEG, RAW, PNG) and common video containers for export.
- Presets for scenes: Dedicated presets for day, golden hour, night-to-day, and HDR time-lapses.
- GPU acceleration: Optional GPU use (CUDA/OpenCL/Metal) for significant speedups on supported hardware.
Typical workflow
- Import the image sequence or video.
- Select scene preset or use auto-detect.
- Preview the flicker curve and enable adaptive smoothing.
- Adjust strength and temporal radius sliders for detail vs. smoothness trade-off.
- Batch process and export stabilized sequence or rendered video.
Best-use tips
- Shoot with consistent white balance and fixed exposure when possible to reduce heavy correction.
- Use RAW source frames when available for better highlight and shadow recovery.
- For sunrise/sunset, increase temporal radius slightly to avoid haloing on rapid exposure transitions.
- Preview at full resolution for critical shots to check for ghosting artifacts.
Limitations
- Extremely rapid, intentional exposure changes (creative ramping) may be smoothed unless masked manually.
- Heavy noise in underexposed frames can amplify after correction; apply denoising first when needed.
