Wrap VideoSpeedPreset conversion in try/except to gracefully handle
invalid speed_str values instead of raising unhandled ValueError.
Logs warning and falls back to None (default) on failure.
Major changes:
- SaveVideo now uses DynamicCombo to show codec-specific encoding options
- When selecting h264 or vp9, quality and speed inputs appear dynamically
- Each codec has unique ADVANCED options (shown in 'Show Advanced' section):
- h264: Profile (baseline/main/high), Tune (film/animation/grain/etc.)
- vp9: Row Multi-threading, Tile Columns
- Quality maps to CRF internally with codec-appropriate ranges
- Speed presets map to FFmpeg presets
New types:
- VideoSpeedPreset enum with user-friendly names
- quality_to_crf() helper function
This demonstrates both DynamicCombo (codec-specific inputs) and advanced
widgets (profile/tune/row_mt/tile_columns hidden by default).

* ComfyAPI Core v0.0.2
* Respond to PR feedback
* Fix Python 3.9 errors
* Fix missing backward compatibility proxy
* Reorganize types a bit
The input types, input impls, and utility types are now all available in
the versioned API. See the change in `comfy_extras/nodes_video.py` for
an example of their usage.
* Remove the need for `--generate-api-stubs`
* Fix generated stubs differing by Python version
* Fix ruff formatting issues
* Add basic support for videos as types
This PR adds support for VIDEO as first-class types. In order to avoid
unnecessary costs, VIDEO outputs must implement the `VideoInput` ABC,
but their implementation details can vary. Included are two
implementations of this type which can be returned by other nodes:
* `VideoFromFile` - Created with either a path on disk (as a string) or
a `io.BytesIO` containing the contents of a file in a supported format
(like .mp4). This implementation won't actually load the video unless
necessary. It will also avoid re-encoding when saving if possible.
* `VideoFromComponents` - Created from an image tensor and an optional
audio tensor.
Currently, only h264 encoded videos in .mp4 containers are supported for
saving, but the plan is to add additional encodings/containers in the
near future (particularly .webm).
* Add optimization to avoid parsing entire video
* Improve type declarations to reduce warnings
* Make sure bytesIO objects can be read many times
* Fix a potential issue when saving long videos
* Fix incorrect type annotation
* Add a `LoadVideo` node to make testing easier
* Refactor new types out of the base comfy folder
I've created a new `comfy_api` top-level module. The intention is that
anything within this folder would be covered by semver-style versioning
that would allow custom nodes to rely on them not introducing breaking
changes.
* Fix linting issue
The frontend part isn't done yet so there is no video preview on the node
or dragging the webm on the interface to load the workflow yet.
This uses a new dependency: PyAV.
