 - **v0.44**: Allow ollama to have a cusom url in the file `ollama_ip.txt` in the comfyui custom nodes folder. Minor changes, add details/updates to README.
 - **v0.45**: Add a new node : Text scrambler (Character), change text randomly using the file `scrambler/scrambler_character.json` in the comfyui custom nodes folder.
+- **v0.46**: ❗ A lot of changes to Video nodes. Save to video is now using FLOAT for fps, not INT. (A lot of other custom nodes do that as well...) Add node to preview video, add node to convert a video path to a list of images. add node to convert a list of images to a temporary video + video_path. add node to synchronize duration of audio with video. (useful for MuseTalk) change TTS node with many new outputs ("audio_path", "full_path", "duration") to reuse with other nodes like MuseTalk, also TTS rename input to "connect_to_workflow", to avoid mistakes sending text to it.

+
+**Description:**  
+
+This node will basically synchronize the duration of an audio file with a video file by adding silence to the audio file if it's too short, or demultiply the video file if too long. (Video ideally need to be a loop, check my ping pong video node.)  
+It is good like for example with MuseTalk <https://github.com/chaojie/ComfyUI-MuseTalk>, If you want to chain up videos (Let's say sentence by sentence) it will always go back to the last frame. (Making the video transition smoother.)  
+
+Here is an example without `Audio Video Sync` node (The duration of the video is shorter than the audio, so after playing it will not go back to the last frame, ideally i want to have a loop where the first frame is the same as the last frame. -See my node loop video ping pong if needed-) :
