Concurrent Submit | zhenzhen-seedance2.5-standard-low-price

ByteDance's Seedance 2.5 video model on the domestic discount site, and the most input-hungry node in this pack: thirty image slots, ten video slots, ten audio slots. That's not decoration - Seedance's whole selling point is multimodal reference, and the multi model variants will actually use a pile of reference frames plus reference clips plus reference audio in one generation. If you've ever wanted to say "make a video that looks like these shots, moves like this clip, and has this sound," this is the wrapper.

It's a video node, so it runs in the shared video pool (10 workers) and returns a COMFLY_VIDEO_FUTURE task. Collect with Concurrent Collect Videos (ComflyConcurrent_Video_Await), which waits on up to 10 tasks and gives you video_1…video_10 in order. And like the other low-price nodes, it takes an api_config from the Comfly Seedance2 Low Price Settings node rather than a bare apikey field.

The inputs

• model - six variants: seedance-2.5-standard-t2v / -i2v / -multi, plus the same three with -global-. The multi variants unlock the reference orgy; the global ones route internationally.
• prompt - the direction, multiline.
• seconds - -1 (auto) or 4–15.
• resolution - 480p, 720p, 1080p, 2k, 4k, or native1080p (the pack's favorite: native 1080p output that the changelog calls "效果炸裂").
• ratio - adaptive, 16:9, 4:3, 1:1, 3:4, 9:16, 21:9.
• image1…image30, video1…video10, audio1…audio10 - the reference buffet.
• generate_audio - on by default (Seedance generates synchronized audio); flip off to save money on silent tests.
• return_last_frame - off by default; enable to get the final frame as a usable still.
• seed - -1 (random) to 2147483647.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/T8mars/Comfyui-zhenzhen

Or ComfyUI Manager → search Comfyui-zhenzhen → restart, then build api_config with the settings node and your domestic token (api.seedance.nz).

Gotchas

• Reference counts are multiplicative, and so is the bill. The README notes that reference video seconds are counted in the price - a 5s reference clip adds to what a 5s output costs. Keep refs short.
• 4k and native1080p are the expensive lanes. "Low price" is the site's discount, not a promise of cheap 4K; the resolution/seconds choice is where the real budget lives.
• The video pool is shared with every video node in the pack. Ten concurrent jobs across all of them - a busy batch will queue. Tune COMFLY_VIDEO_CONCURRENCY if you own the box and want more.
