#Video Resource Import

#Function Introduction

During the initial import phase, video resources rely on the following two key capabilities:

• 1. User Material Collection
  • chooseMedia: Supports end-users in submitting original video materials by either recording videos in real-time or importing from the phone's album.
• 2. Video Pre-standardization Processing
  • clipVideo: Automatically standardizes the resolution and angle of the source video to prevent format differences from causing exceptions in the subsequent AI video generation process.

#Interaction Process

#Considerations

• 1. When using the chooseMedia API, for better compatibility with both iOS and Android systems, please set the parameter isFetchVideoFile to true by default.
• 2. When using the clipVideo API
  • (1) The parameter endTime is in milliseconds, while the video duration returned by the chooseMedia API is in seconds. Please pay attention to unit conversion.
  • (2) The parameter level indicates the compression resolution level of the target video:
    • 1 represents 480854 with a bitrate: 15721000
    • 2 represents 540960 with a bitrate: 21281000
    • 3 represents 7201280 with a bitrate: 31451000
    • 4 represents 10801920 with a bitrate: 35001000
    • To ensure clarity of the output video, it is recommended to choose level 4 for this parameter.
