I've made some progress. I can do decent quality stuff with Wan 2.2 now at reasonable speed *although I miss the Wan 2.6 features I'd grown to like).

I've tried to work with other T2V models, but keep running into issues with them.

For instance, I'm trying to use a workflow template I downloaded for Hunyuan T2V, but the prompts I feed it are being completely ignored, resulting in lovely videos with, say, a woman quietly sipping a cup of coffee -- no matter what I'm actually asking for. Perhaps I can figure out enough about how these workflows work to fix that.

I tried a workflow for LTX 2, and but I kept getting some error message about audio metadata I couldn't solve. I tried to delete everything in the workflow related to video, hoping at least to get a video-only workflow going, but my attempts just made the workflow more broken.

One annoying thing I ran into (even with the Wan 2.2 workflow that works now) is that for some reason SwarmUI demands that the ComfyUI video workflows you use provide a still image output as well as a video output. That wasn't hard to solve for the Wan 2.2 workflow. There was already an image output inside that workflow which could be used to feed another pair of nodes, ImageFromBatch and PreviewImage, to satisfy that requirement.

I've looked at other workflows that only expose a video output, however, no image output, and have yet to find a tool that will pluck a single frame from a video stream so that this annoying (and senseless, as far as I'm concerned) need for an image output can be sated.

As for LoRAs...

I've found a whole bunch which I think will be fun and useful... but putting them to work is going to be a pain. It's hard to know with LoRAs which work with which image and video models. I tried using a futanari LoRA, for instance, and just got abstract splotches of color as a result.

And the LoRAs aren't easy to employ. I'd hoped I could simply have a list of available LoRAs and check off which ones I wanted to use for any given rendering task. Nope! You've got to build specific workflows and wire in each and every LoRA for each particular mix of LoRAs you might want to use together.

Apparently I can use some commercial services like Wan 2.6 from within SwarmUI/ComfyUI, but not by running them locally, but as paid services that run remotely. The cost looks to be a lot cheaper than using such things on a commercial web site, but I'll have to figure out some plan for anonymous payment if I'm going to use these things.

And I might have a tough time solving that stupid image output requirement too.
