| description="<div>Firstly, the Demo generates speech from input-text using facebook's fastspeech2-en-ljspeech from <a href='https://huggingface.co/facebook/fastspeech2-en-ljspeech' target='_blank'>HF hub</a>.<br>Then, takes the input-text and extracts the entities in it using Flair NER model from <a href='https://huggingface.co/flair/ner-english-ontonotes-large' target='_blank'>HF Hub</a>. <br>Then, generate images using <a href='https://huggingface.co/spaces/multimodalart/latentdiffusion' target='_blank'>Multimodalart Space</a> for every entity separately.<br>Creates a video by stringing all the entity-images together. <br>Lastly, Fuses the AI generated audio and video together to create a coherent movie for you to watch. <br><br>A fun little app that lets you turn your text to video (well, in some ways atleast :) ). More the entities in your text, More time to build the output, More fun to watch.<br> Please expect build time of around 10-20 seconds per entity. For instance, in the third and largest example there are 13 entities as per the NER model used here.</div>" , | |
