Can Scholaris process Zoom or Teams recordings?

Yes. Scholaris accepts any standard video format (MP4, MKV, WebM). Zoom and Teams recordings are typically exported as MP4 files, which work directly.

How does Scholaris handle lectures with slides?

Scholaris extracts keyframes at regular intervals and during scene changes. This captures slide transitions, so slides are indexed alongside the spoken content.

Can I search across all my lectures for a course?

Yes. Create a library for each course and add all lecture recordings. You can then search across the entire course's lectures simultaneously.

How to Search Inside Lecture Recordings with AI

The Problem with Traditional Lecture Recording Search

Lecture recordings are among the most valuable and least accessible study resources. Universities record thousands of hours of lectures each semester, but students have no way to search through them. Need to find the lecture where the professor explained Fourier transforms? You either remember which week it was, or you start watching from the beginning. This makes recorded lectures impractical for exam review, paper research, or revisiting complex topics -- exactly the situations where they would be most useful.

How AI Search Works

AI search for lecture recordings combines speech recognition with semantic understanding. The audio is transcribed with timestamps, slides and board content are captured through keyframe extraction, and everything is embedded into a searchable index. The result is like having a searchable, timestamped transcript linked to the video timeline. You can search for a concept and jump directly to the moment the professor explained it.

Step-by-Step Workflow

1. **Upload lecture recordings** -- Upload video files from your LMS, screen recordings, or personal recordings. 2. **Transcription** -- The lecture audio is transcribed with word-level timestamps. 3. **Slide capture** -- Keyframes are extracted to capture slides, whiteboard content, and visual aids. 4. **Speaker identification** -- Distinguish between the professor, guest lecturers, and student questions. 5. **Search by topic** -- Type a concept, theorem, or topic to find when it was discussed. 6. **Study mode** -- Browse the transcript alongside the video for efficient review.

Scholaris Capabilities

Scholaris turns lecture recordings into searchable study resources: - **Full transcription with timestamps**: Every word is mapped to its exact position in the recording. - **Slide and visual capture**: Keyframes capture slides, diagrams, and whiteboard content. - **Cross-lecture search**: Search across an entire semester of recordings at once. - **Concept finding**: Search by topic rather than keywords -- find "derivative of exponential functions" even if the professor said it differently. - **Study-friendly navigation**: Browse the transcript and jump to any point in the video. - **Exam preparation**: Quickly locate explanations of specific topics across all your lectures.
