Samosa

CILicense: GPL-3.0Platforms: Windows and macOS

Samosa is an open-source, dockable rotoscoping panel for Adobe After Effects. It connects After Effects to a local Sammie-Roto-2 runtime so object selection, tracking, matting, removal, export, and import stay inside the After Effects workflow.

Samosa is an independent integration project. It is not an official Sammie-Roto-2 project and is not affiliated with or endorsed by Adobe.

Samosa panel

Documentation:Windows installation | macOS installation | Model installation | After Effects tutorial | Development | Third-party licenses

Status

The current release targets Windows and macOS with After Effects 2021 or newer through CEP. The selector is embedded in the docked panel. A future native Custom Comp UI module can route clicks from the Composition viewer to the same local service API.

Features

  • Multiple objects with include and exclude point prompts
  • SAM2 selection and clip-wide object tracking
  • MatAnyone, MatAnyone2, and VideoMaMa matting adapters
  • MiniMax and OpenCV removal adapters
  • Mask cleanup, growth, antialiasing, and duplicate-frame controls
  • PNG, EXR, and video output with automatic import into the active composition
  • Background jobs with progress, cancellation, and tracked-frame state
  • 100%, 75%, and 50% viewer scaling

Requirements

  • Windows 10/11, or macOS 13 or newer
  • Adobe After Effects 2021 or newer
  • Internet access during runtime and model installation
  • Windows: a supported NVIDIA, Intel, or CPU backend
  • macOS: Apple Silicon MPS acceleration or Intel CPU processing

Samosa installers do not embed model weights or Adobe SDK files. They download a pinned Sammie-Roto-2 source revision, Python runtime, and selected checkpoints during installation or first use.

Install

Download the installer for your platform from the latest release:

  • Windows: Samosa-Setup-1.2.1.exe
  • macOS: Samosa-1.2.1-macOS.pkg

Both installers create a local runtime and configure the After Effects CEP panel. See Windows installation or macOS installation.

Choose one model mode:

  • Standard: installs SAM2 Base now; missing models download when first requested.
  • Complete: pre-downloads every supported model after the restricted-model license notice is accepted.
  • Custom: selects individual model packs to pre-download.

Restart After Effects and open Window > Extensions (Legacy) > Samosa.

See Model installation for exactly what happens when Standard mode encounters a missing model.

Quick tutorial

  1. Open a composition and select exactly one file-backed footage layer.
  2. Open Window > Extensions (Legacy) > Samosa, then choose Load selection.
  3. Click the viewer to add Include points; right-click or switch to Exclude to remove areas. Add another object when needed.
  4. Choose Track objects. Add correction points on problem frames and track again.
  5. Use Matting for refined alpha edges or Remove to fill the selected area.
  6. Under Output, choose the output description, object, format, and destination, then select Export and add to comp.

Exports use readable names such as interview_Hero_Person_matting_matte. See the After Effects tutorial for the complete workflow.

Development

Run the source-only contract suite with any Python 3.10+ interpreter:

python -m unittest discover -s tests -v
node tests/test_panel_runtime.js

Set SAMMIE_REPO and run with the upstream virtual environment to include the deterministic integration suite:

$env:SAMMIE_REPO="D:\path\to\Sammie-Roto-2"&"$env:SAMMIE_REPO\.venv\Scripts\python.exe"-m unittest discover -s tests -v

See Development, Architecture, and Releasing.

Licensing and model restrictions

Samosa source code is licensed under GPL-3.0. It directly integrates with the GPL-3.0 Sammie-Roto-2 runtime, so GPL-3.0 is the conservative and compatible release choice.

Some optional engines exposed through Sammie-Roto-2 have separate noncommercial terms. In particular, MatAnyone uses the S-Lab noncommercial license, while MiniMax Remover and VideoMaMa use CC BY-NC 4.0. Installing or downloading those components does not grant commercial-use rights. Review Third-Party Notices before distributing Samosa or using those engines commercially.

Upstream relationship

Samosa is maintained as a separate repository because it is an After Effects integration and does not modify Sammie-Roto-2 core. Fork Sammie-Roto-2 only if a contribution requires maintaining upstream core patches; submit generally useful changes upstream when possible. See Notice for the exact provenance used during development.

Acknowledgements and connected projects

Samosa exists because of the work in Sammie-Roto-2 by Zarxrax and contributors. The workflows it exposes connect to SAM 2, EfficientTAM, MatAnyone, MatAnyone2, VideoMaMa, and MiniMax Remover. Attribution here does not replace each project's license or model terms; see Third-party notices.

  • Complete: pre-downloads every supported model after the restricted-model license notice is accepted.
  • Custom: selects individual model packs to pre-download.
Restart After Effects and open Window > Extensions (Legacy) > Samosa.
See Model installation for exactly what happens when Standard mode encounters a missing model.
Quick tutorial
  1. Open a composition and select exactly one file-backed footage layer.
  2. Open Window > Extensions (Legacy) > Samosa, then choose Load selection.
  3. Click the viewer to add Include points; right-click or switch to Exclude to remove areas. Add another object when needed.
  4. Choose Track objects. Add correction points on problem frames and track again.
  5. Use Matting for refined alpha edges or Remove to fill the selected area.
  6. Under Output, choose the output description, object, format, and destination, then select Export and add to comp.
Exports use readable names such as interview_Hero_Person_matting_matte. See the After Effects tutorial for the complete workflow.
Development
Run the source-only contract suite with any Python 3.10+ interpreter:
python -m unittest discover -s tests -v
node tests/test_panel_runtime.js
Set SAMMIE_REPO and run with the upstream virtual environment to include the deterministic integration suite:
$env:SAMMIE_REPO="D:\path\to\Sammie-Roto-2"&"$env:SAMMIE_REPO\.venv\Scripts\python.exe"-m unittest discover -s tests -v
See Development, Architecture, and Releasing.
Licensing and model restrictions
Samosa source code is licensed under GPL-3.0. It directly integrates with the GPL-3.0 Sammie-Roto-2 runtime, so GPL-3.0 is the conservative and compatible release choice.
Some optional engines exposed through Sammie-Roto-2 have separate noncommercial terms. In particular, MatAnyone uses the S-Lab noncommercial license, while MiniMax Remover and VideoMaMa use CC BY-NC 4.0. Installing or downloading those components does not grant commercial-use rights. Review Third-Party Notices before distributing Samosa or using those engines commercially.
Upstream relationship
Samosa is maintained as a separate repository because it is an After Effects integration and does not modify Sammie-Roto-2 core. Fork Sammie-Roto-2 only if a contribution requires maintaining upstream core patches; submit generally useful changes upstream when possible. See Notice for the exact provenance used during development.
Acknowledgements and connected projects
Samosa exists because of the work in Sammie-Roto-2 by Zarxrax and contributors. The workflows it exposes connect to SAM 2, EfficientTAM, MatAnyone, MatAnyone2, VideoMaMa, and MiniMax Remover. Attribution here does not replace each project's license or model terms; see Third-party notices.

Samosa
CILicense: GPL-3.0Platforms: Windows and macOS
Samosa is an open-source, dockable rotoscoping panel for Adobe After Effects. It connects After Effects to a local Sammie-Roto-2 runtime so object selection, tracking, matting, removal, export, and import stay inside the After Effects workflow.
Samosa is an independent integration project. It is not an official Sammie-Roto-2 project and is not affiliated with or endorsed by Adobe.
Samosa panel
Documentation:Windows installation | macOS installation | Model installation | After Effects tutorial | Development | Third-party licenses
Status
The current release targets Windows and macOS with After Effects 2021 or newer through CEP. The selector is embedded in the docked panel. A future native Custom Comp UI module can route clicks from the Composition viewer to the same local service API.
Features
  • Multiple objects with include and exclude point prompts
  • SAM2 selection and clip-wide object tracking
  • MatAnyone, MatAnyone2, and VideoMaMa matting adapters
  • MiniMax and OpenCV removal adapters
  • Mask cleanup, growth, antialiasing, and duplicate-frame controls
  • PNG, EXR, and video output with automatic import into the active composition
  • Background jobs with progress, cancellation, and tracked-frame state
  • 100%, 75%, and 50% viewer scaling
Requirements
  • Windows 10/11, or macOS 13 or newer
  • Adobe After Effects 2021 or newer
  • Internet access during runtime and model installation
  • Windows: a supported NVIDIA, Intel, or CPU backend
  • macOS: Apple Silicon MPS acceleration or Intel CPU processing
Samosa installers do not embed model weights or Adobe SDK files. They download a pinned Sammie-Roto-2 source revision, Python runtime, and selected checkpoints during installation or first use.
Install
Download the installer for your platform from the latest release:
  • Windows: Samosa-Setup-1.2.1.exe
  • macOS: Samosa-1.2.1-macOS.pkg
Both installers create a local runtime and configure the After Effects CEP panel. See Windows installation or macOS installation.
Choose one model mode:
  • Standard: installs SAM2 Base now; missing models download when first requested.
  • Complete: pre-downloads every supported model after the restricted-model license notice is accepted.
  • Custom: selects individual model packs to pre-download.
Restart After Effects and open Window > Extensions (Legacy) > Samosa.
See Model installation for exactly what happens when Standard mode encounters a missing model.
