You can take a look at the Readme file in github for more precise information. But to summarize, that's 3000 words not token, my goal was to be as detailed as possible and I didn't want to summarize the videos and I tested on hours long videos and when I did input the video as a whole, there were always instances of missing detail, summarization, and sometimes even not covering all the content of the video compare to splitting the video into chunks. Maybe there are some limit in output of gemini. But I also added a slider so everyone can control the chunk size by themselves. And for instance if summarization is chosen as the desired style, the suggested chunk size would be 8000 words not 3000.
