A workflow that lets you extend a video using any number of frames from the last generation, crop and stitch (automatically resize the cropped image to the given video size then scales it back), and add 1-4 extra frames per run to the generation.Extra frames You can select 1-4 extra frames here. Load image: Load image to be used for this frame. Insert into frame #: select which frame to insert into. Display frame for (pause): Selecting more than 1 will insert more of the same frame, ie. pausing on that frame for the amount of frames selected here.Load models Specify the diffusion model, clip, VAE to be used. Select LoRAs. Adjust model shift.FFLF Select first and last frame (you can turn them off separately in the orange bypasser nodes). The first frame also serves as reference image, unless that's disabled.Main input for stitch Crop area: Select the area you want cropped from the image. Note that while you select a box here, it's ratio will be adjusted to match the video size you choose, so if they are not the same shape (W/H ratio), the crop will be forcefully resized. Check the "Crop preview with mask" to see the actual area of crop overlaid on the control mask; make sure the mask is also similar to the cropped area, the non-white places will NOT get animated! When you use cropping you can't set the upscale size, since it will be scaled back to the initial crop size after it's finished generating. Extra frames: You can turn on/off the additional extra frames here. Select upscale model and factor (latter is only relevant for non-crop-and-stitch workflows).Initial inputs Raw image folder: Type your output folder here. The saved frames will be placed here, labeled normal and upscaled plus the number of runs. Incrementer: Used for indentifying the the number of runs for extending video, most importantly the control frames used from the last video to stitch the extension without losing motion.Bypasses Note that using control frames from last video should not be allowed for the initial, first video, as there will be no frames generated from last run. Another less common thing here is "Use stitch" which is used for the crop-and-stitch videos.Misc settings Number of Control: The number of last frames to be used from the previous run. This helps to keep motion, but as these frames will be cut from the video, will decrease the amount of frames generated. VACE control strength: You can set the strength of contol frames / masks here. Empty white level: set the white level of empty control frames.Stitch final video: Run this node alone, seperately! Enable this at the end of your generation when you are making extensions to your generation. Only enable it after you have all the frames needed generated already, since the workflow will start with this! If you are only doing a single run, preview last video node should suffice.Please consider supporting me <a target="_blank" rel="ugc" href="https://paypal.me/hsagroy">on PayPal! </a>
