⭐ Star Slideshow Maker

You've got a batch of images - a style test, a grid of variations, a storyboard - and you want them as a video with transitions, motion, and maybe music, without leaving ComfyUI. Star Slideshow Maker is a full slideshow encoder in one node: point it at image sockets or a folder, choose the aspect ratio and duration, pick transitions and pan/zoom effects, drop an audio track in, and it renders an H.264/H.265/VP9/AV1 video through FFmpeg.

How it works

The architectural nicety is that frames stream one at a time straight into FFmpeg, so a long slideshow doesn't balloon into a giant IMAGE tensor sitting in RAM. On the control side, the node separates concerns cleanly:

• Sources - connect image_1, image_2, … (they grow dynamically) or set image_folder to a folder of JPG/PNG/WebP relative to your input folder. Connected images are used first, then folder files.
• Size and fit - aspect_ratio (auto, or 16:9 / 9:16 / 1:1 / 4:3 / 3:4 / 21:9) and resolution (HD = 1280 long edge, Full HD = 1920). fit_mode of contain letterboxes with the chosen background; cover center-crops to fill.
• Timing - duration_mode of fixed uses fixed_duration; audio matches the length of the connected audio. Then timing_mode: seconds_per_image repeats the sequence at a fixed length until the total fills, or split_total_duration divides the total equally.
• Transitions and motion - 14 transitions (fade, morph, slides, wipes, zoom, pixelate, random) plus 8 motion effects (zoom/pan variants, random), with seed controlling the "random" picks so you can reproduce a given look.
• Encoding - format, preset, quality, and the same target_size_mb two-pass trick as Star Video Compressor for hitting an exact file size.

save_audio muxes the audio input into the video. Outputs are Filenames (STAR_FILENAMES) and info (STRING), plus an inline preview.

Installing

Part of StarNodes:

cd ComfyUI/custom_nodes
git clone https://github.com/Starnodes2024/ComfyUI_StarNodes
cd ComfyUI_StarNodes
pip install -r requirements.txt

Restart, search star under ⭐StarNodes/Video. ComfyUI Manager users: search "Starnodes". FFmpeg comes via the pack's imageio-ffmpeg dependency.

Gotchas

Transitions are clamped so they can't eat the whole segment, but if you set seconds_per_image to 1 with a 1-second transition you'll basically get a fade-through - keep per-image time well above transition time. For mixed-aspect inputs, cover crops (safe for a consistent fill) while contain letterboxes (safe for showing everything); pick deliberately. And the "random" transitions seed behavior is worth knowing: seed 0 re-rolls every run, any other value reproduces the same picks - perfect for locking a look you like, easy to forget if you want variety.
