How to Make a Reaction Video

AAndrew Best

Quick answer: The best and easiest way to make a reaction video is to do it in your browser with Podsplice. Podsplice lets you capture system audio (the sound from the video you’re reacting to) along with your mic, camera, and screen. With Podsplice, you select mic + camera, share your screen with system audio on, hit Record, and you’re done—in minutes, no installs, no messy plugins.

Podsplice is unique because it records 4 separate tracks locally and syncs them all together automatically.

Podsplice records:

  1. A thumbnail video of your face

  2. The video of whatever is on your screen (screenshare)

  3. The audio of you speaking into your microphone

  4. *** The "system audio" or sound coming from the video you are reacting to (E.g. YouTube video sound). This fourth track is key because most browser-based software products don't record system audio. For example, you can't do this with Canva, Riverside, or Descript.

1) Prep Your Laptop (2 minutes)

Close any programs, browsers, and tabs you aren't using. This is to help your computer run quickly and smoothly.

2) Prep Your Browser (2 minutes)

Reaction videos are super easy and fun to make with Podsplice.

  • Open your favorite browser - E.g. Chrome, Safari, Edge...

  • Go to the video you want to react to - E.g. YouTube video, TikTok, Instagram... (You can open multiple tabs if you are reacting to more than one video)

  • Scroll to the exact part of the video you are reacting to.

  • Open another tab and go to www.podsplice.com (sign in too, obviously)

This is what your initial setup should look like. (Notice one tab with YouTube open and one tabe with Podsplice open)

2) Configure Podsplice (1 minute)

  1. Open Podsplice and login

  2. Click Overdub

  3. Click Share Screen

  4. Click the Settings icon and choose the correct mic and camera (E.g. webcam)

  5. Click Share Screen and choose Entire Screen. ***NOTE: Make sure to toggle "share system audio" to On!

  6. Click on the entire screen square and click "share"

3) Record the Reaction (real time)

  1. In Podsplice, click Record.

  2. Switch to your video tab → press Play at your queued moment.

  3. React naturally. Pause the video to add commentary when you need depth or emphasis.

  4. If using multiple clips, move through your pre-queued tabs in order.

4) Wrap, Sync, and Save

  • When you are finished with the video go back to the Podsplice tab.

  • Click Stop in Podsplice.

  • Your webcam, mic, screen, and system audio are auto-synced for you.

  • Click "Save and go to Editor"

  • Click "Start Processing"

  • Download the finished file and edit wherever you want before uploading to YouTube, TikTok, Instagram or wherever you plan to.

Level-Up: Quick Pro Tips

  • Audio balance: Do a 10-second test to make sure the sound and everything are how you want.

  • Framing & lighting: Eye-level camera, soft front light, clean background.

  • Use pauses on purpose: Pause the clip to deliver punchy thoughts instead of talking over key moments.

  • Cut the air: Trim hesitations and silent scrolling; your viewers will thank you.

Troubleshooting (fast fixes)

  • No video sound in the recording? Re-share the screen and confirm “Share system audio” is enabled.

  • Your voice too quiet? Raise mic input a bit and/or lower the video player volume. Retest for 10 seconds.

  • Laggy playback? Close background apps, drop the player preview resolution if needed, and keep only the necessary tabs open.

Light Copyright Notes (keep you safe, not scared)

  • Fair use basics (U.S./general guidance): Keep clips short, transform with commentary/critique, and add value.

  • Always credit the original creator in your description.

  • If a takedown happens, trim the flagged portion and re-upload.
