This guide walks you through exactly how to make vertical chat conversation videos, whether you want a fake WhatsApp chat video or an AI-powered chat story for Reels. Let’s dive in!

Step 1: Plan Your Chat Story and Script

Every great chat story video starts with a believable, engaging script. Think of your video as a mini-movie played out through messages. Decide:

• Story Type: Is it a dramatic reveal, a comedy bit, a Reddit story video, or a fake text argument?
• Characters: Choose sender names and their personalities. More distinct voices make the conversation feel real.
• Message Order & Pacing: Organize the chat so the story unfolds naturally, with suspense or punchlines at the right moments.

Tip: Write your script in any note app first. Use realistic language, typos, emojis, and reactions. Think about how people actually text!

Step 2: Choose Your Chat Style—WhatsApp, iMessage, Messenger, or Custom UI

Picking the right chat platform look is crucial. Audiences instantly recognize fake WhatsApp chat videos or iMessage stories. Decide which fits your story best:

• iMessage: Apple’s blue/grey bubbles are perfect for drama and are instantly familiar.
• WhatsApp: Green/white chat bubbles and double checkmarks are great for global stories.
• Messenger: Facebook’s style with profile icons and colored bubbles for group chats.
• Custom: Some fake text message video makers let you create your own chat look—ideal for unique brands or parody.

Many AI chat video generator tools and apps let you switch between these UIs. Preview your script in each style to see what feels most authentic.

Step 3: Set Up a 9:16 Vertical Canvas for TikTok, Reels, or Shorts

Short-form platforms demand a vertical 9:16 aspect ratio (1080x1920 pixels). This format is non-negotiable for TikTok, Instagram Reels, and YouTube Shorts.

• Start your project in a video editor (like Canva, CapCut, After Effects, Remotion, or similar) with a vertical canvas.
• Many AI video clip generators now automatically prepare vertical chat overlays for you.
• If repurposing existing footage, crop or reframe it to fit vertical. Most editors let you drag the chat UI into place as an overlay.

Step 4: Build the Animated Chat Conversation

This is where your fake text message video comes to life. Use your chosen app or editor to enter each message, sender name, and time stamp. For maximum realism:

• Add each chat bubble one by one—never all at once.
• Space out messages using timing controls so they appear like a real conversation.
• Include typing indicators (three dots), read receipts, or message reactions for authenticity.
• Use emojis, voice notes, and media (photos, audio, GIFs) just like real chats.

Some AI chat video generators can animate the entire dialogue for you, but manual timing lets you control the suspense and pacing.

Step 5: Add Voiceover, Hooks, and Captions for Retention

Voiceover is optional but powerful. Narration can add context, drama, or humor—especially for Reddit story videos or text story explainers.

• Record your voice (or AI voice) reading the messages, or add sound effects for message notifications.
• Start the video with a strong hook—use a question, dramatic line, or visual cue to grab attention.
• Use captions/subtitles for accessibility and to keep viewers watching even with sound off. Vidulk offers easy caption customization right in the editing screen.
• Try the Free Hook Generator for irresistible video intros.

Retention is key: the faster and more engaging your chat story, the longer people will watch.

Step 6: Use AI Tools or Chat Video Generators for Speed

If you want to save time, AI-powered fake text message video makers or chat story generators can handle much of the heavy lifting:

• Paste your script or long-form video, and let AI generate the chat animation and timing.
• Customize sender names, add media, and tweak the pacing as needed.
• Apps like Vidulk can clip the best moments from interviews or podcasts, then help you build chat overlays and captions in minutes.

Step 7: Export in Vertical MP4/MOV and Double-Check Platform Settings

When your chat video is ready, export it for social media:

• Set output to 9:16 vertical (1080x1920 pixels).
• Format: MP4 or MOV are the most widely supported.
• Double-check that all chat bubbles, captions, and overlays are visible and not cut off by platform UI.
• Preview on your phone before posting. Each platform may crop edges slightly—especially TikTok and Reels.

Tips & Common Mistakes

• Don’t rush the pacing: Let chat bubbles appear naturally, not all at once.
• Avoid robotic scripts: Use slang, typos, and emojis for realism.
• Keep it vertical: Don’t forget to use the 9:16 aspect ratio from start to finish.
• Test on multiple devices: Make sure all text and bubbles are readable on small screens.
• Watch your copyright: Only use media (images, GIFs) you have the right to share.

Many creators stumble at the export step—always preview before uploading to avoid cut-off messages or awkward cropping.
