LTX 2.3 I2V + Audio Workflow that allows Multiple Loras to be uploaded in addition to the base distilled Lora

This workflow has been slightly modified from it's original version which was made by user @ukr8b3g20 which was already pretty user friendly

For my version all I really did was just move some stuff around, color code and bypass those two "LTX2 Mem Eff Sage Attention Patch" nodes within the main ltx node subgraph because it kept giving me an error but once I bypassed them it began to work just fine for me, this workflow is still pretty fresh so I haven't had much time to explore and test it with different loras quite yet.

This is basically the LTX 2.3 equivalent to my other Wan 2.2 Beginner I2V workflow, it's made so that you don't have to worry so much about precision and understanding and you can just input and generate away! If you need basic setup knowledge check my instructions for my Wan 2.2 I2V Workflow on my profile.

Basic visual guide for this workflow:

One thing to always check is make sure that the audio duration and video duration are always matching and I've found that when I generate multiple videos the ltx video duration settings will sometimes reset to its default 1024 x 700 dimensions so I'd recommend always double checking the width & height to make sure it's what you actually set it to!
