Video Loading and Management
- Video Provider: Aegisub allows you to choose the method for loading video files. The options include *Avisynth* (for Windows, supporting various formats including AVI and DVD VOBs) and *FFmpegSource* (generally the most reliable option, using FFMS2 to load video).
- Open, Close, and Recent Videos: You can open, close, or view a list of recently opened video files from the video menu. This helps in managing multiple video files efficiently.
Video Display and Playback
- Show Video Details: This feature displays information about the currently open video, including filename, frames per second, resolution, aspect ratio, length, and the decoder used to open the file.
- Seek Video to Line Start: When enabled, Aegisub will automatically seek the video to the first frame of the new line whenever the active line is changed. This can also be done manually by double-clicking on the grid or pressing Ctrl-1.
Keyframe and Marker Management
- Show Keyframes in Slider: Aegisub can draw keyframe markers on the video seek slider, making it easier to identify keyframes while navigating the video.
- Snap Markers: When enabled, audio markers will snap to other markers in the audio display, such as keyframes and the start or end times of other lines, if they are close enough. This can be toggled on or off by holding down the Shift key.
Visual Tools and Display
- Video Position: A line can be drawn in the audio display marking the start time of the current video frame, helping to synchronize audio and video.
- Always Show Visual Tools: This option determines whether the visual typesetting tools are always rendered or only when the mouse is over the video display.
Automation and Convenience
- Automatically Open Audio: When enabled, Aegisub will automatically load the audio when opening a video file that contains audio data.
- Fast Jump Step: This setting decides how big the “jumps” Aegisub will make when using the fast seek feature (Alt-right arrow and Alt-left arrow), measured in frames.
Backup and Autosave
While not directly related to video tools, these features are crucial for overall workflow:
- Automatic Save: Aegisub can periodically save a copy of the script you are working on to a specified autosave path, ensuring your work is protected against unexpected interruptions.
- Automatic Backup: Aegisub can save a backup copy of each script you open immediately upon opening it, which is saved to a specified backup path.
