✂️ Video Editor
Built-in video editing tool — two modes in one page: 🎬 Video Edit (trim/merge clips) and 🎞️ Image Slideshow - Match SRT (build an image slideshow timed to subtitles). Access via the Video Editor button on the sidebar.
Video Editor uses bundled FFmpeg (no extra install). It auto-selects GPU encoding (NVENC/QSV/AMF) when available, otherwise CPU (libx264).
Both export actions (Export Video and generate Slideshow) require the MAX plan. You can import/trim/arrange/preview freely on any plan — the Max-required popup only appears when you click export.
6.1 Interface & Two Modes
At the top of the page is a mode bar with two buttons (the page always opens in Video Edit):
| Mode | Purpose |
|---|---|
| 🎬 Video Edit | Trim, split, arrange and merge multiple clips into one video |
| 🎞️ Image Slideshow - Match SRT | Build a slideshow video from images, auto-timed to an SRT subtitle file + background music |
The mode decides which toolbar, timeline rows, and bottom panel are shown. Overall layout, top to bottom:
| Area | Description |
|---|---|
| Mode bar | Video Edit / Image Slideshow buttons |
| Toolbar | Import, Split, Delete, Clear, Export, Undo/Redo, save folder 📁, help ❓, zoom slider (20–500%) |
| Timeline (multi-track) | Video Edit: Video row only. Slideshow: 3 rows — Images / Subtitle (SRT) / Audio |
| Bottom panel — left | Video Edit: Media Pool. Slideshow: Slideshow Options + Image Pool |
| Bottom panel — right | Preview — player + transport controls |
| Status bar | Clip count, total duration, playhead position |
6.2 Video Edit Workflow
- Import videos: Click 📥 Import Video or drag & drop files into the Media Pool / Timeline
- Add to Timeline: Select clips in the Media Pool → click ➕ or drag them onto the Video row
- Arrange: Drag a clip body to reorder (orange drop indicator)
- Trim: Drag the left/right edges of a clip to trim the start/end

Untrimmed clips are merged by stream-copy (very fast, lossless). Trimmed clips are re-encoded (libx264 CRF 18, AAC 192k audio). The Video timeline has no transitions or subtitle/audio overlay (subtitles + music live in Slideshow mode).

6.6 Slideshow Mode — Match SRT 🎞️ ⭐
Build a slideshow video from a set of images, auto-timing each image to a subtitle line in an SRT file, with optional background music.
Workflow
- Switch to 🎞️ Image Slideshow - Match SRT
- Images (required, ≥1): drag onto the Images row or click 📥 Add Images. Images are ordered by natural filename order (img2 before img10) → name them numerically to match subtitle order
- Subtitle SRT (optional, one file only): 📥 Pick SRT. Importing a new one replaces it
- Audio (optional, multiple): 📥 Add Audio
- Set options in the Slideshow Export Options panel (below)
- Click 🎞️ Export Video → choose output (a .mp4 file for "Full video", or a folder for "Separate clips")
Slideshow options
| Group | Option | Details |
|---|---|---|
| Export mode | Full video (merge all) / Separate clips (one file per image) | Default: Full video → one MP4. Separate clips → one MP4 per image into a chosen folder |
| Duration per image (when NO SRT) | Fixed / Random / Fit to audio | Fixed: 1–60s (default 8s). Random: min–max (default 4–8s). Fit to audio: splits the music length evenly across images |
| Motion effects (Ken Burns) | Pan left / right / up / down, Zoom in, Zoom out | 6 checkboxes. Each scene picks a random effect from those enabled (no two adjacent scenes repeat). Leave empty = static images |
With an SRT file: each image is timed to a subtitle line; the first image also covers the lead-in (0 → the start of the first subtitle line). Fewer images than lines → the last image is reused (looped). If audio is longer than the SRT → the last image holds to the end of audio (no black tail). The "Duration per image" options are then ignored.
Output
- MP4 (H.264), 30 FPS. Resolution is taken from the first image (put a correctly-sized image first) — there is no separate FPS/aspect option
- No effects + Full mode → fast concat (images letterboxed to fit). Any effect or Separate clips → per-scene render with Ken Burns (images fill the frame)
- Filenames: Full →
slideshow_YYYYMMDD_HHMMSS.mp4. Separate → aslideshow_<timestamp>/folder ofNN_<image name>.mp4files
Slideshow formats: Images .png .jpg .jpeg .webp .bmp · Audio .mp3 .wav .m4a .aac .ogg .flac · Subtitle .srt
6.7 Export (Video Edit)
- Merges all Video-row clips into a single MP4 file
- Choose the output folder via the 📁 field on the toolbar (remembered across sessions)
- Progress bar shows % (Trim clips → Merge → Done)
- Default filename:
merged_YYYYMMDD_HHMMSS.mp4
