How to watch educational videos faster in Chrome
A 2-hour course does not have to take 2 hours. With the right playback tools you can cut watch time by 30–50% while retaining just as much — here is how.
- 1Step 1
Start at 1.5× and move up gradually
Jumping straight to 2× can hurt comprehension at first. Start at 1.5×, spend 10 minutes, then nudge up. Glitch lets you tap the speed button in small increments.
- 2Step 2
Enable pitch correction
Without it, voices at 1.75× start sounding unnatural and distracting. Glitch locks pitch by default so speech stays clear and easy to follow at any speed.
- 3Step 3
Turn on Smart Speed for silence skipping
Lectures often have 1–3 second pauses between thoughts. Smart Speed (Pro) automatically skips those gaps — typical time savings are 10–15% on top of manual speed.
- 4Step 4
Bookmark key moments instead of rewinding
When a concept needs to stick, press the bookmark key instead of scrubbing back later. Glitch bookmarks include a label field so you can note what you marked.
- 5Step 5
Use frame-by-frame for dense slides or diagrams
If a diagram or slide is on screen for just a second, frame-step backward to catch it without scrubbing. Glitch's frame keys let you step one frame at a time.
FAQ
- Will speeding up a Coursera or Udemy video affect my course completion?
No. Glitch controls speed locally in your browser. The course platform sees you as watching the video normally and marks it complete as expected.
- What is the fastest comfortable speed most people use for lectures?
Most people settle between 1.5× and 2× for lectures. With a familiar speaker or a second watch, 2.5×–3× is achievable.
- Is there a limit on how many bookmarks I can add?
Bookmarks are unlimited and free. Notes are 3 per video on the free plan and unlimited with Pro.
