LTX-2.3-Workflows

RuneXX workflows do have a switch for either text or image, its right above the audio section towards the bottom of WF. From my experience, from other WF's, it still needs an image as a placeholder even though the WF will not use. Just use the example.png image that is in your \ComfyUI\ComfyUI\input, as your placeholder, hopefully you have it in there, if not just use anything you have handy.

Thank you very much for your help. I must be misunderstanding something; here's what I have:
I have inserted a Image:

I have toogled the switch:

But the video starts still with the input image and makes a hard cut after some seconds. It still uses I2V instead of T2V. I will check, what the Set_t2v_mode really does:

Could be a slip, that this was not connected to the ImgInPlace bypass.
Will check

Checked, and all seems ok.
Ran a test run, and all works my end.

Check if somehow the bypass ("t2v_mode") get node got disconnected from the LTXImgToVideoInPlace node (its 2 places, once in 1st pass, and then in 2nd pass)

Thank you. Noted just know, that it is only in the "LTX-2.3_-I2V_T2V_Basic_ID-Lora_reference_audio" workflow. My bad, works in the "LTX-2.3-_I2V_T2V_Dev_Custom_Audio" workflow.

Will check LTX-2.3_-I2V_T2V_Basic_ID-Lora_reference_audio if maybe something is not connected there ;-)

Your solution does work. LTXVImgToVideoInplace bypass do the trick. Thank you!

Indeed, it was an oversight on that one. In the LTXImgToVideoInPlace (its twice in the workflow), just click the toggle "Bypass"

Uploaded an updated workflow though, so you could also download it again.

ah yes, you already figured out the manual toggles

The workflows are really great. Thank you for your help!
