WAN 2.1 I2V/T2V. I tested the rel L1 thresh values of 0.12, 0.25, and 0.3, but none of them could accelerate the process. However, setting FirstBlockCache to 0.1 can double the speed, but the quality drops significantly.

There are obvious quality issues with TeaCache, and FirstBlockCache didn't improve the speed.

Did you try using the "ApplyTeaCachePatchAdvanced" node?

I don't know what value to set "start_at" but I assume the quality drop is caused when the value is set to 0 or a not high enough number, because kijai nodes come with start_at set to "6".

try add steps to 30.

start_at and end_at is range in 0-1, like control's start_percent and end_percent

For i2v, it seems like the width and the height of the node WanImageToVideo will effect quality of the TeaCache in my test.

This node is still unusable with Wan, Kijai's version of teacache remains the most efficient for the time being.

It seems like kj used another way of TeaCache, I will try it tomorrow.

https://github.com/ali-vilab/TeaCache/tree/main/TeaCache4Wan2.1 Can author take a look at its implementation method?"

thks, I will check it later.

Submitted, please update the latest version.

[zaitaxiang2012]

Thank you. I will provide the latest test results.

[zaitaxiang2012]

First of all, thank you for your efforts. However, after testing, the video quality still cannot be satisfactory.

Did you try change wan_coeffiecents?
