Abstract: Embodiments of the present disclosure provide a video editing method and apparatus, an electronic device, and a storage medium. The method comprises: creating at least one editing subtask for a video editing task; in response to a first operation for triggering a target editing subtask, obtaining an initial video material and presenting an editing interface of the target editing subtask; recording the editing operation triggered in the editing interface and presenting an indication identifier of the editing operation in the editing track; generating an editing result of the target editing subtask based on the recorded information of the editing operation and the initial video material; based on the editing result of each editing subtask of the video editing task, generating a target video as an editing result of the video editing task.

Abstract: For in mold spraying, a double-inclined mixing nozzle is connected obliquely and fixedly with a side surface of a third half-mold through a lateral sealing structure and connected with a side surface of a first half-mold in an inclined and sealing manner, side faces of a first half-mold and the third half-mold are respectively provided with installation inclined surfaces. A lateral sealing structure includes a mounting plate and a sealing member. The sealing member is sleeved on the double-inclined mixing nozzle and is in transition fit with the double-inclined mixing nozzle and the mounting plate respectively. A butt sealing groove provided on the installation inclined surface of the first half-mold and is in sealing fit with the mounting plate.

Abstract: A method and device for automatic film expansion and a storage medium are provided. The method includes the following. Perform overall stretching on an expanded film. An interval between each two adjacent LED wafers on the expanded film is monitored in real time. When an interval between two adjacent LED wafers on the expanded film is greater than or equal to a preset target interval, stop performing overall stretching, and search the expanded film for a local region where an absolute difference between an interval between two adjacent LED wafers and the preset target interval is greater than a preset error threshold. When the local region exists on the expanded film, perform local stretching on the local region until an absolute difference between an interval between each two adjacent LED wafers in the local region and the preset target interval is less than or equal to the preset error threshold.
