Why turn a video into flashcards
Many courses today are recorded as video: filmed lecture halls, online conferences, internal pro trainings, webinar replays. The problem is video is a passive format. You watch, you follow, but you don't test memory while watching. Without active recall, video learning is poorly durable.
Flashcards turn the video into an active tool. You watch once to understand, then revise with an auto-generated deck. The video becomes a durable investment.
Difference from YouTube
For YouTube videos, we just use the public link. For local video files (recorded lecture, private filmed conference, unpublished replay), Diane processes the file directly. So you can exploit content that isn't online.
Typical cases: you record your lecture with your phone, you get a pro webinar replay by email, you have a downloaded course MP4. All these formats work without going through YouTube.
Accurate transcription
AI uses top-tier speech recognition, multi-speaker (useful for conferences with several presenters), with solid handling of technical terms and proper nouns. Accuracy is high for main languages.
For videos with burned-in subtitles or a separate subtitle file (.srt, .vtt), Diane uses these subtitles first if you also upload them.
Timestamps and navigation
Each flashcard is linked to the exact video moment it came from. When reviewing, clicking the timestamp opens the video at the source passage. Useful to verify what the teacher actually said, or to replay a technical segment.
Use cases
Students: convert a recorded lecture into a study deck, turn an online course replay into flashcards. Pros: exploit a video-distributed internal training, keep content from a filmed conference. Self-learners: seriously exploit a downloaded video on your computer.
