Project class

Project class.

Project(project_id: str)

Bases: pytvpaint.utils.Refreshable, pytvpaint.utils.Renderable

A TVPaint project is the highest object that contains everything in the data hierarchy.

It looks like this: Project -> Scene -> Clip -> Layer -> LayerInstance

Render the project to a single frame or frame sequence or movie.

Parameters:

Name	Type	Description	Default
output_path	pathlib.Path | str | fileseq.filesequence.FileSequence	a single file or file sequence pattern	required
start	int | None	the start frame to render or the mark in or the project's start frame if None. Defaults to None.	None
end	int | None	the end frame to render or the mark out or the project's end frame if None. Defaults to None.	None
use_camera	bool	use the camera for rendering, otherwise render the whole canvas. Defaults to False.	False
alpha_mode	pytvpaint.george.AlphaSaveMode	the alpha mode for rendering. Defaults to george.AlphaSaveMode.PREMULTIPLY.	pytvpaint.george.AlphaSaveMode.PREMULTIPLY
background_mode	pytvpaint.george.BackgroundMode | None	the background mode for rendering. Defaults to george.BackgroundMode.NONE.	None
format_opts	list[str] | None	custom format options. Defaults to None.	None

Raises:

Type	Description
ValueError	if requested range (start-end) not in project range/bounds
ValueError	if output is a movie, and it's duration is equal to 1 frame
FileNotFoundError	if the render failed and no files were found on disk or missing frames

Note

This functions uses the project's timeline as a basis for the range (start-end). This timeline includes all the project's clips and is different from a clip range. For more details on the differences in frame ranges and the timeline in TVPaint, please check the Usage/Rendering section of the documentation.

Warning

Even tough pytvpaint does a pretty good job of correcting the frame ranges for rendering, we're still encountering some weird edge cases where TVPaint will consider the range invalid for seemingly no reason.
