Currently retiming is quite awkward, when you need to retime multiple strips strips in sync. It is possible to use meta strips, but this is still not great. This is resolved by implementing selection. General changes: Gizmos are removed, since they are designed to operate only on active strip and don't support selection. Transform operator code is implemented for retiming data, which allows more sophisticated manipulation. Instead of drawing marker-like symbols, keyframes are drawn to represent retiming data. Retiming handles are now called keys. To have consistent names, DNA structures have been renamed. Retiming data is drawn on strip as overlay. UI changes: Retiming tool is removed. To edit retiming data, press Ctrl + R, select a key and move it. When retiming is edited, retiming menu and context menu shows more relevant features, like making transitions. Strip and retiming key selection can not be combined. It is possible to use box select operator to select keys, if any key is selected. Otherwise strips are selected. Adding retiming keys is possible with I shortcut or from menu. Retiming keys are always drawn at strip left and right boundary. These keys do not really exist until they are selected. This is to simplify retiming of strips that are resized. These keys are called "fake keys" in code. API changes: Functions, properties and types related to retiming handles are renamed to retiming keys: retiming_handle_add() -> retiming_key_add() retiming_handle_move() -> retiming_key_move() retiming_handle_remove() -> retiming_key_remove() retiming_handles -> retiming_keys RetimingHandle -> RetimingKey Retiming editing "mode" is activated by setting `Sequence.show_retiming_keys`.
