Questions about Wan I2V & Animate

I have a few questions I've been struggling with trying to learn to use Wan 2.2 Animate, and also how to improve Wan length in general.

1. First, for Wan 2.2 Animate I almost gave up on it at first because the results I was getting were awful. Then after trying multiple different tutorials and eventually trying some of their inputs for testing I found out there was a huge hidden factor that none of the online tutorials I've come across, nor online discussions in general, seem to cover and maybe it is why Animate is almost never talked about on here because people just do not know. One was that frame rate of input loaded video must, absolutely, match the frame rate chosen. For most things this seems to be 16 because inability to do long videos and clip duration. After finding this out it improved results considerably but this seems really inconvenient and limiting. Is there anything else I'm missing here?

2. On the same topic does anyone have a good resource or tutorial explaining how to do infinite length videos, like Kijai's context window stuff for infinite duration? I couldn't find any that actually covered it because they just clickbait title "Infinite length" and then, in the video, they're like here is context windows but we're going to disable and skip that for now and never actually covers it... and couldn't find any website or info on Kijai's github but maybe I'm blind and missed it. Also, does this actually let you do infinite length, like insert a 5 or 20 minute video and it keeps doing context sliding until completion? Or will I eventually OOM on my RTX 4090? Based on the sliding context my initial interpretation was it basically incremented the video in batches of X frame count so as long as I could do a single batch I would never OOM until video completed successfully as long as configured properly but I'm not sure if I'm understanding it correctly. If there is one that shows how to do this with i2v, too, (would like to use for animate and i2v workflows) and actually teaches me to properly use it I'll take it, too. I'll take a website (no video) version if there isn't a better video showing it in practice, as well, I just know that on technical stuff like this they often are neglectful and don't show intermediary steps sometimes.

3. Also, would this also mean my issue of input video fps since it could run at a higher FPS, but since it would just keep doing it until Animate has been applied to the entire clip it wouldn't matter if each segment was 2s higher fps vs 5s 16 FPS? Or would that not help, or perhaps I'm misunderstanding something? In the event this is impractical is there a node I can use to segment a video. Ex. every 80 frames and the iterates, preferably with the ability to set when it starts and ends so if I didn't want to animate an entire video but didn't want the inconvenience of having to splice it with a 3rd party app... If there is a node and workflow that helps with this please share.

4. The other issue I noticed was the results seem really unbelievably bad at lower resolutions for Animate so I couldn't process faster at lower and then upscale later, or even really do some low quality tests to confirm changes worked. The results were almost always someone else, entirely, looking nothing like the input person. Is there a trick I'm missing? Any tips about the resolution for Animate, in general, I should be aware of? Could the input resolution of my character matter, too? I'm just resizing and padding edge with resize image v2 or whatever node.

5. For i2v if I learn context and can use it to do longer videos is there a way to give iterative steps per context window? Ex. the first 1-2 get into position or perform soemthing to setup the scene, then next set of iterations for X number of runs performs whatever action with some variety via wildcards or whatever, then after I can have for iterations after X number begin performing Y number of a new task? Ex. characters getting into position and powering up, then a specific type of melee fight for several iterations in i2v, followed, then using special abilities like energy attacks, etc.

6. Is there a trick to improving how well Animate adheres to the input character's identity? I've noticed with some clips it performs quite well but not perfect, but then others no matter who I use for input it just fails. Also, it seems that the underlying character's body type needs to be extremely similar, not just somewhat similar or it just doesn't work at all?

Honestly, any tips about getting infinite length working and, in general, how to make Animate results actually good would be great. Seen many YouTube, Patreon, and Google/reddit posts about Animate workflows and stuff and they don't even cover stuff like frame rate issues, resolution, etc. properly and their results often only work well with their specific test input materials and not in general with other video clips. Really wondering if Animate is just that finnicky and genuinely not worth it or not. Even more confused, because I've seen some insanely good like 3-5 minute clips of Animate on this sub and I just don't understand how they achieved that. I've been focusing, so far, on Kijai's workflow, in case it helps, as the native comfyui workflow honestly seems to completely fail when I try it... I've been especially focusing on his v2 workflow recently, but have tried both.

Any help is appreciated.
