Model overview

The autocaption model is a Cog implementation of a tool that automatically adds captions to videos. It is created by the team at Fictions.ai. This model can be useful for automatically generating subtitles for videos, which can improve accessibility and make content more engaging for viewers who may not have the audio on or who prefer reading captions.

The autocaption model has some similarities to other video transcription and captioning models like whisperx-video-transcribe and text-to-speech models like styletts2, but it is focused specifically on the task of adding captions to existing video files.

Model inputs and outputs

The autocaption model takes a video file as its main input and generates a video file with captions overlaid on top. It also has several customization options, including the ability to adjust the font, color, size, and position of the captions.
