WIP project by Kijai Info/Setup/Install guide: <a target="_blank" rel="ugc" href="https://civarchive.com/articles/8313">https://civarchive.com/articles/8313</a> Requires Torch 2.5.0 minimum, so update your Torch if you are behind. As with the CogVideo Workflows, they are provided for people that want to try the Preview :) Even with a 4090 it can push the limits a little, I provide my workflows used to research Tile Optimisation in V1;<ol><li>We're reducing tile sizes by roughly 20-40% from the defaults</li><li>We're increasing the frame batch size to compensate</li><li>Maintaining the same overlap factors to prevent visible seams</li></ol>Key principles:<ul><li>Tile sizes should ideally be multiples of 32 for most efficient processing</li><li>Keep width:height ratio similar to the original tile sizes</li><li>Frame batch size increases should be modest to avoid frame skipping </li></ul>Researchers Tip! If you work with a fixed seed, the sampler remains in memory, so the first gen took ~1700 seconds, however, changes to the Decoder can be made which means that the next video will take ~23 seconds. All the work is already done by the Sampler, so unless we take a new seed it will use the samples over and over, VAE decode speed is very good! <img src="https://i.gyazo.com/b1fcf3b3c53a2725b1bd339fa94c7e2c.png" />^ subsequent gens on same seed are very fast, allowing tuning of the decoder settings ^ <img src="https://gyazo.com/ed5db27c27496d56e55d6e47d0e08d52.png" />^ initial generation was taking ~1700 with pytorch 2.5.0 SDP ^ <h2 id="v1-workflows:-79xgplbx7">V1 Workflows: </h2>outputs labelled and added to V1 gallery, test prompt used: "In a bustling spaceport, a diverse crowd of humans and aliens board a massive interstellar cruise ship. Robotic porters effortlessly handle exotic luggage, while holographic signs display departure times in multiple languages. A family of translucent, floating beings drift through the security checkpoint, their tendrils wrapping around their travel documents. In the sky above, smaller ships zip between towering structures, their ion trails creating an ever-changing tapestry of light." \Decoder-Research\Donut-Mochi-848x480-batch10-default-v5 = Author Default Settings<ul><li>This version used the recommended config from Author</li></ul> \Decoder-Research\Donut-Mochi-640x480-batch10-autotile-v5 = Reduzed size, Auto Tiling - This is my first run which created the video in the gallery, simply using Auto Tile on the decoder and reducing the overall dimensions to 640x480. This reduction makes generation take less memory, but is heavy handed and will reduce the quality of outputs.The remaining workflows are all Investigating the possible configs, without using Auto Tiling so we know what was used exactly.

(pytorch SDP used) <h2 id="v3-workflows-argzh15gf"> V3 Workflows </h2>\FP8--T5-Scaled\Donut-Mochi-848x480-batch16-CFG7-T5scaled-v8We decided to use the FP8_Scaled T5 CLIP model, this improved the outputs greatly across all prompts tested. check the v3 gallery. This is the best so far ! (until we beat it)\GGUF-Q8_0--T5-Scaled\Donut-Mochi-848x480-b16-CFG7-T5scaled-Q8_0-v9This did not yield the best results, probably due to T5 scaled Clip still being in FP8 as we were testing the use of GGUF Q8_0 as the main model.<h2 id="v4-workflow-1s0vuacbt">V4 Workflow </h2>\T5-FP16-CPU\Donut-Mochi-848x480-b16-CFG7-CPU_T5-FP16-v11used T5XXL in FP16 by forcing it onto the CPU. Seems like the same artifacts from V3 where we used GGUF Q8_0 with T5XXL FP8.<h2 id="v5-workflows-sdkd5qi51">V5 Workflows</h2>\GGUF-Q8_0--T5-FP16-CPU\Donut-Mochi-848x480-GGUF-Q8_0-CPU_T5-FP16-v14This was the best settings with VAE Tiling enabled, increasing the steps of course will increase the quality and the time taken. Increasing steps to 100-200 is increasing quality at the expense of time taken, 200 steps takes 45 minutes. Likely no version for this because anybody can add more steps to any of these workflows and just wait a very long time for a 6 second video. This can be remedied with a Cloud setup and more/larger GPU/VRAM allocation. <h2 id="v6-workflows-465f1qzvb">V6 Workflows </h2>\Fast-25-Frames\Donut-Mochi-848x480-Fast-v4Used VAE Tiling with 25 frames to generate 1 second of video. with 50 steps this takes a few minutes, 4-5 minutes for 100 steps.\NoTiling-SaveLoadLatent\Donut-Mochi-848x480-i2v-LatentSideload-v21Using my new DJZ-LoadLatent Node, you can save the sampler results as .latent files on the disk, this makes it possible to decode the latents as a separate stage, eliminating the need for the Tiling VAE. This is image to video, and used OneVision to estimate a video prompt from any given image, it also automatically detect Tall or Wide Aspect ratio and crops/fills to 16:9 or 9:16. NOTE: more testing must be done to prove that Tall Aspect Quality is good.\NoTiling-SaveLoadLatent\Donut-Mochi-848x480-t2v-LatentSideload-v25 This is the text to image version of the previous workflow, we drop OneVision and ImageSizeAdjusterV3 and add Zenkai-Prompt-V2 back in to take advantage of our prompt lists. Full instructions are found in the workflow notes. Save/Load Latent approach allows us to drop the Tiling VAE, which introduced ghosting to all videos regardless of the settings, as we achieved improved quality the ghosting becomes more apparent.<h2 id="v7-workflows-9qeap5w87">V7 Workflows</h2>Updated the V6 latent sideload workflows to use the newer VAE Spatial Tiling Decoder This can run 100% on local GPU, and all the demo videos in the gallery used on 50 steps (100 steps used in the V6 gallery) another significant upgrade !\V7-Spatial-Tiling-VAE\Donut-Mochi-848x480-t2v-LatentSideload-v50.json<ul><li>text2video, VAE spatial tiling decoder, with my latent loader</li></ul>\V7-Spatial-Tiling-VAE\Donut-Mochi-848x480-i2v-LatentSideload-v50.json<ul><li>pseudo image2video, VAE spatial tiling decoder, with my latent loader</li></ul>\V7-Spatial-Tiling-VAE\Donut-Mochi-848x480-t2v-BatchLatentSideload-v55.json<ul><li>text2video, VAE spatial tiling decoder, with my V2 batched latent loader</li></ul>\V7-Spatial-Tiling-VAE\Donut-Mochi-848x480-i2v-BatchLatentSideload-v55.json<ul><li>pseudo image2video, VAE spatial tiling decoder, with my V2 batched latent loader</li></ul> NOTE: V7 is available on Github in my DJZ-Workflows pack, however it will not get published here until the new batch of videos are finished (cooking all night tonight) <h2 id="v8-workflows-jp7f8dtbj"> V8 Workflows</h2>\True-Image-To-Video\Donut-Mochi-848x480-i2v-LatentSideload-v90.json<ul><li>image2video, VAE spatial tiling decoder, with my latent loader</li></ul>\True-Image-To-Video\Donut-Mochi-848x480-i2v-BatchedLatentSideload-v90.json<ul><li>image2video, VAE spatial tiling decoder, with my V2 batched latent loader</li></ul>Added true i2v (image to video using new VAE Encoder) tutorial video TBA. details in the <a target="_blank" rel="ugc" href="https://civarchive.com/articles/8313">main article</a>
