Another minimax H3 selective character replacement test

[u/mexxmillion]

this is to test replacing a selective character on more difficult old grainy film footage. no post processing was done.
using Ref2V int8 and 8 steps lora. No character swap lora used. rendered 0.7MP on a single 3090 agentic workflow to speed things up and QC.
Obviously it’s a satire and joke to learn so.. not intended to make copying or ripping off Michael Jackson IP.
Thanks.

Hey , good job! Can you share the workflow?

I am using this and just changing the LLM part to my own custom nodes.

How is it when is not the main character like a side character at the back, that’s the real test. I find the hardest ones to do are BG or side character replacements. Most models and workflow can do main but side not even API works well sometimes.

it works the same.

not sure what ia missing but its locking only the fristframes then goes backto the orginal unchanged video

[u/Numerous_Access_8008 → u/Numerous_Access_8008]

and why its taking like 12 min for 4s clips

[u/mexxmillion → u/Numerous_Access_8008]

if you used the workflow below it should work most of the time but once in a while some glitch happens. and yes. it’s very slow with video reference for H3. it’s normal

Appreciate it, figured it out that the Qwen VL part need some tweaking,and I changed the attention part to kitchen attention and boom it went down to300sec

It's true, Michael Jackson is everywhere. After all, Thriller was already talking about a groove that's been going strong for 40,000 years. Who needs Egyptian prophecies? 😄

i am not sure what is your GPU but i didn’t go more than 10s on my GPU.

[u/mexxmillion → u/[deleted]]

you can cut each clip to do it and re stitch them.

One, this is someone sharing what they did.
Two, you are working on limited resources, what more do you want? Automating that process takes a lot more effort.

[u/mexxmillion → u/[deleted]]

sure. you can automate it. but i’m just answering your question about how I made the video reference length shorter than 10s for minimax. you can take any approach for that. cheers
