If you are updating from 2.1.0 later, you can simply overwrite the existing files. If updating from an older version, please run the installer again in order to update dependencies.

Changes:

• Support for VideoMaMa matting model, optimized to run in 6GB VRAM at the smallest resolution. Thanks @wiltonflame for help with integration.
• Added option to the matting page to combine all objects, letting you process multiple objects together at once.
• All model downloads now happen on demand when you try to use them, rather than during installation. No need to download models you don't want to use.
• Moved segmentation model selection from the settings page into the Segmentation tab.
• Segmentation postprocessing now correctly applies when running matting.
• Preliminary support for Intel Arc.
• Fixed a bug from version 2.1 that caused bad segmentation output when using multiple points.
• Fixed a bug from version 2.2 causing models to be hashed every time they were loaded, causing delays in loading.

If you are updating from 2.1.0 or 2.1.1, you can simply overwrite the existing files. If updating from an older version, please run the installer again in order to update dependencies and models.

Changes:

• Added support for MatAnyone 2. The new model will automatically be downloaded when you attempt to use it.
• Fixed an issue with the splash screen not showing on some Linux systems. #35
• Fixed issue with incorrect line endings on the install/run scripts for linux/mac. #24
• Fixed issue with zip package not opening on some linux/mac systems. @ # #41

If you are updating from 2.1.0, you can simply overwrite the existing files. If updating from an older version, please run the installer again in order to update dependencies and models.

Changes:

• Rebuilt the export dialog, fixed some export bugs, add support for exporting PNG sequence. #28 #27
• Fixed some typos in the installers #34
• Load dependencies for matanyone and minimax remover only when they are used. Speeds up initial application startup time.

If you are updating to this version from a previous release, it is highly recommended to run the installer again in order to update dependencies and models.

Changes:

• Added support for In/Out points for processing a frame range rather than the entire video. #22
• Making changes to points no longer automatically clears existing tracking and matting data.
• Added back the EfficientTAM model that was in Sammie-Roto version 1. This is a much faster but less accurate alternative to SAM2. It is only recommended for users without hardware acceleration and for situations where the reduced accuracy is acceptable.
• Run Segmentation at half precision. This should give a major speedup on systems with hardware acceleration.
• The export dialog will remain open after exporting, so you can export multiples files in succession.
• Text in messages boxes can now be selected for copy/paste. #23 By @Mark-Shun
• The install script for linux and mac systems has been updated.
• Bump Pytorch version to 2.9.1. Version 2.9.0 had bugs which could cause performance issues or crashes.

If you are updating from the beta release, simply extract the zip in the same location, overwriting the existing files.

Changes:

• Added drag and drop support to load files.
• Added button to toggle points list between all frames and current frame
• Added individual {date} and {time} tags for export filenames
• Export dialog will prompt to create the output folder if it doesn't exist
• Replaced emoji icons with image icons, due to emoji not appearing on some systems
• Improve visualization when multiple points selected in the points list
• Performance improvement when deleting multiple points
• Deduplication threshold added into the settings dialog
• Scroll bar added to the settings dialog to prevent it growing too tall
• Deduplication now makes a backup of the original masks so you can run deduplication with different threshold without having to track objects again
• Changed file extension used for settings files, to prevent accidentally overwriting them when saving points list
• Display an error if the Sammie-Roto folder does not have write permissions
• Fixed matting-alpha output type not exporting the correct data
• Fixed issue causing the vae tiling setting to not work at all
• Fixed file extensions not getting added to points and project files on linux
• Fixed object removal not working at some resolutions
• Fixed some bugs related to session settings being overwritten or reset
• Fixed some bugs related to tracking/deduplication status indicators
• Fixed the antialias checkbox appearing on some views where it is not used
• Fixed some color issues with the dark theme
