ComfyUI Node: 🔢 Frame Set Index Offset

Frame Set Index Offset [DVB]:

The Frame Set Index Offset [DVB] node is designed to adjust the starting index of a sequence of frames by a specified offset. This node is particularly useful when you need to shift the entire frame set to start from a different index, which can be essential for synchronizing frames with other sequences or aligning them within a larger project. By applying an offset to the frame indices, you can ensure that the frames are correctly positioned in the timeline, making it easier to manage and manipulate video content. This node simplifies the process of reindexing frames, allowing for more flexible and precise control over your frame sequences.

Frame Set Index Offset [DVB] Input Parameters:

frames

This parameter represents the frame set that you want to reindex. It is a collection of frames that will be adjusted based on the specified offset. The frame set should be of the type FrameSet.TYPE_NAME.

offset

The offset parameter specifies the amount by which the starting index of the frame set should be adjusted. It is an integer value that can be positive or negative, allowing you to shift the frame indices forward or backward. The default value is 0, meaning no offset is applied. Adjusting this value will change the starting index of the frame set, which can be useful for aligning frames with other sequences.

Frame Set Index Offset [DVB] Output Parameters:

frames

The output parameter frames is the reindexed frame set. This frame set has its indices adjusted based on the specified offset, ensuring that the frames start from the new index. The reindexed frame set maintains the same frame content and framerate as the original, but with updated indices to reflect the applied offset.

Frame Set Index Offset [DVB] Usage Tips:

• Use the offset parameter to align frame sets with other sequences in your project, ensuring synchronization and proper positioning.
• Experiment with positive and negative offset values to see how they affect the starting index of your frame set, allowing for flexible adjustments.
• Combine this node with other frame manipulation nodes to create complex video editing workflows that require precise control over frame indices.

Frame Set Index Offset [DVB] Common Errors and Solutions:

Frame set contains gaps!

• Explanation: This error occurs when the frame set has missing indices, which can cause issues during reindexing.
• Solution: Ensure that your frame set does not have any gaps in the indices before applying the offset. You can use nodes like DVB_UnwrapFrameSet with the gap_mode set to BLEND to handle gaps.

Frame set type mismatch

• Explanation: This error occurs when the input frame set is not of the expected type FrameSet.TYPE_NAME.
• Solution: Verify that the input frame set is correctly formatted and of the type FrameSet.TYPE_NAME before using this node.
