A basic img2img script that will dump frames and build a video file. Suitable for creating interesting zoom in warping movies, but not too much else at this time. The basic idea is to story board some kinf od animation with changes in prompts, translation etc at a low framerate until you get it roughly right. Then bump up the framerate for a final render, it should play out roughly the same, just more detail.
This is intended to be a versatile toolset to help you automate some img2img tasks. It certainly isn't a one stop shop for digital movies.
Inspired by Deforum Notebook Must have ffmpeg installed in path. This suffers from img2img embossing, if the image is static for too long. I would have to look at someone else's implemetation to figure out why and don't want to steal their code.
Broken down the growing prompt into individual commands to control various parameters. Added requested features. Rolled in changed from pull requests, thanks to contributers.
Changed the interpolation system, so various keyframes write values into a frame dataframe. Blank values are then interpolated, so transform changes are smoother. also used to interpolated prompts by default now.
Investigating seed marching. Look at some scripts and figured out how subseeds are meant to be used. Implemented it as an option. If you add seed keyframes and check the seed march box, the script will migrate from one seed to the next using the subseed & subseed strength interpolation. if you leave seed march unckecked, the seed value will interpolate from one integer to the next. View the final values in the dataframe .csv dump in the output folder.
Seed marching doesn't seem to work well with transforms, if you combine them you'll get poor results.
Added some different sources for frames. If video is specified, frames will be grabbed from the supplied video file, until the end of the video is hit. Then the last frame will be repeated (i think). Images works silimarly, but you need to specify a path and wilcard file name, such as c:/images/*.png. A list of images will be created, alphabetically sorted by default. If there are not enough images for the specified duration, the last frame will be repeated.
Specifying a different source other than img2img means the initial image in the UI will be ignored, but it needs to be there for the UI to work.
Create GIF, webM or MP4 file from the series of images. Regardless, .bat files will be created with the right options to make the videos at a later time.
Total number of seconds to create. Will create fps frames for every second, as you'd expect.
Frames per second to generate.
Initial denoising strength value, overrides the value above which is a bit strong for a default. Will be overridden by keyframes when they are hit. Note that denoising is not scaled by fps, like other parameters are.
Experimental option to enable a half-life decay on the denoising strength. Its value is halved every second. Not that useful because of img2img embossing.
Initial zoom in (>1) or out (<1), at this rate per second. E.g. 2.0 will double size (and crop) every second. Will be overridden by keyframes when they are hit.
Shift the image right (+) or left (-) in pixels per second. Will be overridden by keyframes when they are hit.
Shift the image down (+) or up (-) in pixels per second. Will be overridden by keyframes when they are hit.
Provide common positive and negative prompts for each keyframe below, save typing them out over and over. They will only be applied when a keyframe is hit. The prompts in the keyframes will be appended to these and sent for processing until the next keyframe that has a prompt.
Key frames have been broken down into individual commands, since the old keyframe was blowing out. Commands:
"time_s | source | video, images, img2img | path
"
Set source of frames for processing. Format: time_s | prompt | positive_prompts | negative_prompts
- time_s: Time in seconds from the start to make the change.
- prompt: video, images, img2img
- path: Either the file name of the video file, or the path and wildcard filename of the images.
Set positive and negative prompts. Format: time_s | prompt | positive_prompts | negative_prompts
- time_s: Time in seconds from the start to make the change.
- prompt: Command name.
- positive_prompts: Replacement positive prompts. Will be concatenated with the positive template.
- negative_prompts: Replacement negative prompts. Will be concatenated with the negative template.
Set positive and negative prompt template. Purely saves filling out the boxes above in the web UI. Format: time_s | prompt | positive_prompts | negative_prompts
- time_s: Time in seconds from the start to make the change.
- template: Command name.
- positive_prompts: Replacement positive prompts. Will be concatenated with the positive template.
- negative_prompts: Replacement negative prompts. Will be concatenated with the negative template.
Set the current transform. Format: time_s | transform | zoom | x_shift | y_shift | rotation
- time_s: Time in seconds from the start to make the change.
- transform: Command name.
- zoom: New zoom value. 1 = 100% per second. 2 = zoom in 200% over 1 second.
- x_shift: X shift value, in pixels per second.
- y_shift: Y shift value, in pixels per second.
- rotation: Rotation, in degrees per second.
Force a specific seed. It's technically a thing you can do, how usefull it is, is up to you to decide. Format: time_s | seed | new_seed_int
- time_s: Time in seconds from the start to make the change.
- denoise: Command name.
- denoise_value: New denoise strength value.
Set the denoise strength. Format: time_s | denoise | denoise_value
- time_s: Time in seconds from the start to make the change.
- denoise: Command name.
- denoise_value: New denoise strength value.
Overlay a rounded text box in post processing. I.e. only applied to the image that is saved, and it not iterated on. Text boxes are referenced by the name you give. If you set it again, you can change the contents. Or it can be cleared. Multiple text boxes with different names can exist at the same time. Format: time_s | set_text | textblock_name | text_prompt | x | y | fore_R | fore_G | fore_B | back_R | back_G | back_B | font_name | font_size
- time_s: Time in seconds from the start to make the change.
- set_text: Command name.
- textblock_name: Unique name or tag given to this text block in the set_text command above.
- text_prompt: Text to put in the text block. You will can use \n for multi-line.
- x: Top left X position of the text block.
- y: Top left Y position of the text block.
- fore_R: RGB values, in base10, for the text.
- fore_G:
- fore_B:
- back_R: RGB values, in base10, of the background bubble.
- back_G:
- back_B:
- font_name: name of the font file. Python will attempt to scan your system font folders for this file.
- font_size: Font size, in pixels i think.
Remove a named text box, it will no longer be drawn on the saved images. Format: time_s | clear_text | textblock_name
- time_s: Time in seconds from the start to make the change.
- clear_text: Command name.
- textblock_name: Unique name or tag given to this text block in the set_text command above.
Embed a clipart image into the picture to be diffused. it will be drawn once at this time. You need to set a prop folder where transparent pngs are held, and specify them by file name. Format: time_s | prop | prop_filename | x_pos | y_pos | scale | rotation
- time_s: Time in seconds from the start to make the change.
- prop: Command name.
- prop_filename: Name of a picture in the props folder, hopefully with transparency.
- x_pos: Center position of the prop.
- y_pos: Center position of the prop.
- scale: Scale value. 1=100% etc.
- rotation: Rotation, in degrees.
Like props but applied in post processing and will not be diffused. You ca reference them by name, change their details on the fly as with text boxes. Format: time_s | set_stamp | stamp_name | stamp_filename | x_pos | y_pos | scale | rotation
- time_s: Time in seconds from the start to make the change.
- set_stamp: Command name.
- stamp_name: Unique name or tag given to this stamp. Used to change it's parameters or delete.
- stamp_filename: Name of a picture in the props folder, hopefully with transparency.
- x_pos: Center position of the stamp.
- y_pos: Center position of the stamp.
- scale: Scale value. 1=100% etc.

- clear_stamp: Command name.
- stamp_name: Unique name or tag given to this stamp in the set_stamp command above.
Allows you to change the model on the fly, if you need to. It won't change it back at the end, so if you do use this, maybe set the initial model in frame 0 first. Format: time_s | model | model_name
- time_s: Time in seconds from the start to make the change.
- model: Command name.
- model_name: Pick one from the list. Just the name with no extension or hash is fine.
