Abstract: A control circuit including a storage circuit, a voltage detection circuit, a processing circuit, and a wake-up circuit is provided. The storage circuit includes a register and stores a program code. The voltage detection circuit detects an external voltage. The processing circuit accesses the register in response to the external voltage reaching a first predetermined voltage. The processing circuit enters a power-down mode in response to the external voltage reaching a second predetermined voltage. In the power-down mode, the processing circuit stops accessing the register. The wake-up circuit determines whether a wake-up event occurs. In response to the wake-up event, the wake-up circuit directs the processing circuit to exit the power-down mode and enter an operation mode. In response to there being no wake-up event, the processing circuit stays in the power-down mode. In the operation mode, the processing circuit executes the program code.

Abstract: Various embodiments are disclosed for facilitating selective rendering during video editing. In accordance with one embodiment, a method of editing video comprises obtaining a video editing project, the video editing project including at least one video clip and timing information corresponding to the at least one video clip. The method further comprises obtaining a reference file generated according to the video editing project and obtaining, from a user, a modification for at least one segment in the video editing project. Based on the modification, each of the at least one segment is identified as a modified segment or an unmodified segment. Based on the identification of at least one modified segment, at least one corresponding segment is extracted from the reference file.
