Live streaming is one of the best ways to connect with your audience in real time, and reaction videos are especially fun. Whether you’re breaking down a new music video, reacting to trending TikToks, or sharing your thoughts on a live event, you don’t need a complicated studio setup.

All it takes is your iPhone, the Detail app, and a couple of simple accessories.

When Live Reaction Streams Really Shine

Before we jump into the setup, let’s talk about why this is useful.

• Music & Pop Culture Reactions

  Your favorite artist just dropped a new track? Go live and react with your community the moment it’s out. People love hearing genuine, unfiltered takes.

• Trending TikTok Compilations

  Scrolling through funny or viral TikToks? Stream your reactions as you watch—your audience gets to experience it with you, in real time.

• Gaming & Esports Moments

  Maybe you’re not a gamer with a full streaming rig, but you can still react to highlight reels, live tournaments, or announcements.

• Community Engagement

  Fans send you links to react to? Stream your responses live, shout them out, and turn reactions into an interactive hangout.

This is where the simplicity of the setup makes a big difference, you can go live from anywhere, anytime, without missing the moment.

What You’ll Need

The setup is super light:

• Your iPhone with the Detail app installed

• Tripod (sturdy enough to hold your phone steady)

• Earphones (to avoid echo while the video plays)

• Microphone (optional, but a USB-C mic or wireless mic will make your audio sound much better)

• Laptop (just at the beginning, to grab your stream key from YouTube, Twitch, or whichever platform you’re streaming to)

That’s it, you don’t need fancy gear or extra software.

Step 1: Get Your Stream Key

On your laptop:

• For YouTube: go to Create > Go Live > Stream Key and copy it.

• For Twitch: go to Settings > Stream, copy your key.

• For other platforms you can search the fastest way to get your stream key.

In the Detail app:

• Start a new project

• Tap the three dots, select Live Stream

• Choose your platform and paste in the stream key

Pro tip: With Detail Pro, you can stream to two platforms at once (like YouTube and Twitch).

Step 2: Choose Your Reaction Video

Pick a video from YouTube, TikTok, or Instagram. Tap Share > More > Detail > Reaction Video.

The video will load into the Reaction layout:

• The video plays in the background

• You appear picture-in-picture (with green screen mode on by default)

Step 3: Customize Your Stream

Before you go live, you can:

• Add overlays (text, images, doodles)

• Change your background (use a solid color or a photo from your camera roll)

• Adjust layout (split screen, bubble, or default PIP)

• Set where you want to start in the video (skip ahead or start from the beginning)

Step 4: Go Live

Once your layout looks good:

1. Plug in your earphones and mic

2. Mount your phone on the tripod

3. Tap the three dots > Live Stream

4. Select your platforms

5. Hit Go Live

And just like that, you’re streaming your reaction live to the world.

Why This Setup Works

• Fast: you can go from idea to live in minutes

• Flexible: works with YouTube, Twitch, Instagram, LinkedIn, or any platform with a stream key

• Professional: overlays, audio controls, and layouts make your stream feel polished without extra editing

Final Thoughts

If you’ve ever wanted to stream your reactions but felt like the gear or software was too complicated, this setup is for you. You can be live on YouTube or Twitch, reacting in real time, with nothing more than your phone.
