The BCC+ Retimer ML filter is a 32 bit hardware accelerated effect, the central core of which is a powerful ML trained engine, can be used for slo-mo or super slo-mo clip retiming delivering superb results in any supported host application. It’s also very easy to understand and use, with a clean clutter-free control panel.
There are two ways to control time with this filter - Speed and Time Offset.
The Speed parameter can be set without using keyframes to any value, positive or negative, to achieve a global slo-mo effect - a value of 50 equates to a 2x slo-mo, a value of 25 yields a 4x super slo-mo. The Speed parameter can also be controlled with keyframes to generate amazing retimed effects, such as slowing a clip to a full stop, then moving in reverse, then ramping back up to full forward speed.
The Time Offset parameter can be used to retime the media in such a way that the current frame is the frame number plus the value set in the time offset parameter. This feature can be very helpful if you just want to change the start frame to something other than the actual start frame.
Presets and the FX Editor
The FX Editor provides a convenient way to store and retrieve factory installed and/or user generated filter presets. To select a preset, open the FX Editor interface and pick one from the Presets panel. Click the apply button in the FX Editor to return to the host user interface.
To save a custom preset, click the “Create Custom Preset” icon in the top right corner of the parameter list, next to the filter name, set a name for the new custom preset in the dialog that appears and click done.
Filter Parameters
Mocha Mask and Track provides a way for the user to select and track which pixels in the filtered source are actually going to be affected by the filter, via the generation of image based mattes, gradient mattes and vector shape masks. Mocha planar tracking and vector shape masking options are included in the PixelChooser, which allows for the generation of motion-tracked mask shapes as a hold-back mask.

Compare Mode
The BCC Compare Mode provides a convenient mechanism to compare the effect result with the original source layer. It provides several variations on basic split-screen views with the filtered clip placed next to the unedited original.

Model: Selects the machine learning algorithm used in the effect.
- Retiming ML 1.0: selects the first generation of the algorithm.
Speed: Used to control the speed of the filtered source. A setting of 100 is neutral, a setting of 0 stops the frame from advancing, a setting of 200 causes the frames to advance twice as fast as normal. Used to
Time Offset: Used to control the clip time by offsetting the current frame. A setting of zero has no effect, a setting of 100 moves the source media so that the current frame is frame 100 from the filtered source.
Tip: You can control retiming based on frame number instead of speed percentage by setting Speed to 0 and then keyframing the Time Offset (frame units) parameter instead.
Alpha Aware: Enable to preserve the alpha channel in the filtered source.
GPU Rendering: This popup allows toggles renderer in use for the filter.
- Default: By default the filter will utilize the installed video card and bases the render on the project settings.
- 16 Bit Float: Sets the render to 16 bit float
- 32 Bit Float: Sets the render to 32 bit float
- Disabled: Disables GPU rendering and switches to software rendering.
