LtxAdd - V2V ADD AUDIO AND EXTEND ANY VIDEO (ltx2.3)
This is another App Mode I know I will use a LOT.
It will ADD AUDIO AND EXTEND any video!
I modified the original experimental following workflow from RUNEXX for my own needs
LTX-2.3_-_V2V_Foley_Add_Sound_To_Any_Video
Changed the models to the ones used by the Vanilla LTX2.3 Comfyui Template
so if you already have those original models it's an out of the box experience :)

Use this workflow to add audio to an existing video and extend it by 10 or 20 seconds; the input is a video, and the output is an extended video with added audio.
Its processing path includes video loading, LTX-2 prompt generation, audio and video combination, and spatial upscaling.
Input: an existing video.
