ITL Multi Video Loader Advanced

The Advanced version of ITL's Multi Video Loader takes everything the basic node does - up to 8 clips on one node, each with its own video_N and audio_N socket, decoded lazily by default - and adds a filename_N output per file.

If you've ever stared at a video workflow with four clips loaded and no idea which socket carries the close-up and which carries the wide shot, you know why filenames matter. With filename_N exposed as a string, you can wire it into a display node, a text label, or a downstream save so the graph tells you what's playing where. It's the difference between a workflow that documents itself and one that requires a memory of what you dragged in last week.

Everything it inherits

The mechanics don't change from the basic node:

• force_rate = 0 (default) keeps every clip at its native frame rate and returns video_N without decoding a single frame - the free path. Any other value retimes all clips to that rate (dropping or duplicating frames, real duration preserved) but forces a full decode, so it costs time and memory. Only set it when you genuinely need a uniform rate across mixed-fps clips.
• audio_N is decoded separately (PyAV, which ships with ComfyUI), so it's available even on the lazy video path. Clips with no decodable audio track yield None on that socket - same as an unplugged OPTIONAL input.
• output_slots - auto or pinned 1–8 to keep wires in place while swapping files.
• Row on/off toggle - keeps socket position but outputs None for video_N, audio_N, and filename_N. Safe for OPTIONAL inputs downstream, fatal for REQUIRED ones.
• count - enabled files actually emitted, not row count.

Reordering files shifts what each socket carries, and the node flags it in its status line when a wired socket is affected. Check your connections when you see that warning.

Outputs & install

Outputs: count (INT), then per file video_N (VIDEO), audio_N (AUDIO), filename_N (STRING) - 25 sockets at full load, which is why auto output slots keep the node small until you actually need it.

Install via ComfyUI Manager (search "ComfyUI-IntoTheLatent-Utils") or:

cd ComfyUI/custom_nodes
git clone https://github.com/Into-The-Latent/ComfyUI-IntoTheLatent-Utils

then restart. No extra dependencies.

Basic vs Advanced: if your pipeline needs to reference the source filenames at all - for naming output files, for logging, or just to keep the graph legible - take Advanced. If you're only routing clips to a sampler and a save node, the basic loader is leaner and there's nothing wrong with it.
