Image Sequence to Timelapse Builder

Image Sequence to Timelapse Builder is a desktop timelapse and stop-motion video assembly
studio for Linux photographers, animators, and creators.
An independent Linux alternative to Corel VideoStudio timelapse and stop-motion workflows,
it organizes sequential still photographs (.jpg, .png, .webp) by natural filename or EXIF
capture timestamp and encodes smooth 1080p and 4K videos via FFmpeg.

Key Features:
- Natural Filename & EXIF Timestamp Ordering: Loads folders of JPEG, PNG, and WebP photos,
reads EXIF DateTimeOriginal capture timestamps and per-frame luminance metrics, and
supports custom frame-hold multipliers for stop-motion animation.
- Temporal Deflicker & Luminance Curve: Plots measured frame-by-frame exposure luminance
alongside a smoothed moving-window curve and applies FFmpeg temporal deflicker filtering
to reduce intervalometer exposure flicker.
- 1080p & 4K H.264 / VP9 Encoding: Renders from 1 to 60 FPS via the FFmpeg concat demuxer
into 1080p Full HD, 1440p QHD, 4K UHD, or vertical 9:16 formats with automatic aspect
letterbox/pillarbox padding or center-crop scaling.
- Optional Audio Track Mux & Built-In Preview: Muxes external WAV, MP3, FLAC, OGG, or AAC
soundtracks with automatic duration trim and fade-out, complete with integrated playback.
