Check the showcase for examples. The default Negative Prompt should be enough for most cases - if necessary delete or add prompts to it.Set how long you want your video to be. Its set to 10 seconds by default.<ul><li>IMG2VID and TXT2VID WORKFLOW</li></ul>Both workflows follow the same format. Set the resolution and the frame rates for the Audio and Video. Its set to 25 frames by default as thats the LTX default setting. Some people also try setting it to 30 frames with good results, so give it a try as well.There isn't much else to try since any small change can make a huge difference: The Seed/Noise, the Sampler (euler is set by default) and CFG are readily available for new values. So change any of them if needed.But for mode advanced users here is how everything else its organized:<ol><li>There are four Subgraphs: Image Setup, Sampler 1, Sampler 2 and Decode. Each has a very simple, easy to follow, set of nodes. It should make it easy to find or change what you think its necessary.</li><li>Image Setup has a very simple upscaling. Its like this to make generation fast. Make changes to upscaling methods here.</li><li>Sampler 1 and Sampler 2 have the samplers where you can change the ManualSigmas.The workflows have different default ManualSigmas on their Sampler 1. Both workflows have the same default ManualSigmas on their Sampler 2. Make sure to change it to your preferred values.</li><li>Decode has the final decoder. It uses all the standard decoders. Very Simple. If use have a prefered VAE decoder just change it here.</li></ol>
