App Settings

The settings screen is located in the upper right corner of the main window. In this screen, you can change the default application settings.

FPS (Frames Per Second)

FPS defines how many frames will be extracted per second. The default is 3.5 frames per second, meaning it extracts 3.5 frames per second.

You can also change the FPS to an integer value, for example: 2, 3, 4, etc. frames per second.

Frame Naming Pattern

The naming pattern defines how frame files will be named. The pattern uses the %04d syntax to represent a 4-digit numeric sequence.

Default naming pattern: %04d.jpg

Examples of custom patterns:

• frame_%02d.jpg - 2-digit sequence: frame_1.jpg, frame_2.jpg, frame_3.jpg, etc.
• frame_%04d.jpg - 4-digit sequence: frame_0001.jpg, frame_0002.jpg, frame_0003.jpg, etc.
• %04d.jpg - only numbered frames without prefix: 0001.jpg, 0002.jpg, 0003.jpg, etc.

The output format is defined by the file extension, for example: jpg, png, webp (depends on FFmpeg support).

Extract Subtitles

This option allows you to extract subtitles from the video, if the input file contains embedded subtitles.

Example: Videos in MKV format often contain subtitles that can be extracted.
