The student player
What your students see, which tools appear when, and the shortcuts worth telling them about.
Tools appear only when there is content behind them
The player does not show empty panels. A chapters button appears once you add chapters; a quiz button once you generate a quiz. Students only ever see tools that will actually do something.
Playback controls
The settings gear holds everything that changes how the video plays.
| Control | What it does |
|---|---|
| Speed | 0.5x to 2x. Popular for revision. |
| Quality | Auto, or a fixed level when the connection is unreliable. |
| Audio | Switch soundtrack when you have added alternate audio. |
| Captions | Pick a subtitle language, plus three caption styles. |
| Version | Switch between separately recorded language versions. |
Auto quality suits most Indian networks
Auto adapts as bandwidth changes, which matters on mobile data. Students on a very unstable connection sometimes prefer pinning 360p to avoid mid-lecture quality shifts.
Touch gestures
On phones and tablets, the video area responds to the gestures students already know from YouTube.
| Gesture | Result |
|---|---|
| Single tap | Play or pause |
| Double-tap left | Back 10 seconds |
| Double-tap right | Forward 10 seconds |
| Double-tap centre | Enter or exit fullscreen |
| Press and hold right | Play at 2x while held, back to normal on release |
Repeated double-taps stack, so four quick taps on the right jump forty seconds and show the running total.
Keyboard shortcuts
On a laptop, the usual video shortcuts all work.
| Key | Action |
|---|---|
Space | Play / pause |
J / L | Back / forward 10 seconds |
← / → | Back / forward 10 seconds |
↑ / ↓ | Volume up / down |
Hold L | Play at 2x while held |
F | Fullscreen |
M | Mute |
B | Bookmark this moment |
0–9 | Jump to that point (5 = halfway) |
< / > | Slow down / speed up |
Study tools
These appear when the corresponding content exists. Several are generated with AI — see AI dubbing & study tools.
Chapters
A jump list plus markers on the seek bar. Add these yourself on the video page.
Transcript
The full text alongside the video, highlighting the current line and scrolling as it plays. Students can click any line to jump there. It can sit beside the video, below it, or in a completely separate box elsewhere on your page.
Search
Searches the transcript and jumps to a hit. This is what students use when revising and they remember a phrase but not where it was.
Bookmarks
Students mark a moment with the B key or the bookmark button and return to it later. Limit is 50 per video.
Bookmarks need a real identity
Bookmarks are hidden for anonymous viewers. Without a per-student identity everyone would share one set, so pass a viewerId if you want this feature.
Notes, quizzes, flashcards and mind maps
AI-generated from the English caption track. The quiz opens automatically when the lecture ends, which tends to lift completion rates. Notes can be downloaded as a PDF branded with your institute's details.
On-video vocabulary
When enabled, defined terms pop up with a short definition as they are spoken. Useful for technical subjects and for students studying in a second language.
Player styles
Each video can use one of three looks, set on the video page.
- Standard — dark and professional. Suits competitive exam and professional courses.
- Playful — purple and vivid, with colourful chapter markers. Aimed at school-age learners.
- Kids — warm green, large icons, bold headings, for young children.
Transcript placement
Add a parameter to the embed URL to control where the transcript sits.
<!-- Beside the video -->
<iframe src="https://videokavach.com/embed/vid_abc123?captions=side"
width="960" height="420" frameborder="0" allowfullscreen></iframe>
<!-- Below the video -->
<iframe src="https://videokavach.com/embed/vid_abc123?captions=below"
width="720" height="576" frameborder="0" allowfullscreen></iframe>To place the transcript somewhere else entirely — a sidebar, or under a course description — use the paired embed codes on the video page. Both iframes share a pair value and stay in sync with each other.
Your branding
Under Settings → Player branding you can add your logo (PNG or SVG, up to 512 KB), choose its corner and size, and set an accent colour used for highlights throughout the player.
Bottom-right is the safe corner
Top corners can overlap the player controls on small screens. Bottom-right keeps the logo visible without covering anything students need to tap.
