Hi, I just tried LTX 2.5 I2V, works great and fast for 5sec vids (like 2mn30 or so without Sage Attention), I have a 3090, 128Gb RAM, 150GB disk space but if I try 10sec (in medium res) it gets stuck forever in the decoding phase just before the video appears. On the console it's exactly like a successful 5 sec video, the only thing missing is the line "Prompt generated in 254 seconds" that you see in green.
Am I alone ? Any idea about what the issue might be ?
Go into the subgraph and change the VAE Decode (Tiled) node's tile size from 768 to 512.
