How to Turn Discord Calls or Streams Into LinkedIn Clips

To share highlights from a Discord call or stream as LinkedIn-ready vertical clips, you’ll need to record, trim, and format your video to fit LinkedIn’s specs. Here’s how to do it efficiently using Vidulk.

Discord Call / Stream to LinkedIn Clips: Step-by-Step Guide

1. Record Your Discord Call or Stream

Discord does not provide a built-in way to clip or export calls and streams. To capture your content:

Use OBS Studio (free) to record your screen, voice call, or stage event.
If available, use Discord’s experimental clip feature for short moments.
Export the recording as an MP4 file. Note: Discord’s upload limit is 20 MB, so for high-quality clips, plan to post directly to LinkedIn or other social platforms.

2. Prepare Your Recording for LinkedIn

LinkedIn accepts video in a wide range of aspect ratios (vertical 9:16, 4:5, square, and landscape all work), with a maximum length of 15 minutes. For best results with short clips, use vertical 9:16 (1080x1920) or 4:5 (1080x1350).

Keep clips concise and engaging - LinkedIn viewers prefer direct, value-packed moments.
Auto captions can be toggled on during upload, but adding captions beforehand ensures accuracy and immediate accessibility.

3. Use Vidulk’s AI Clipper to Create LinkedIn-Ready Clips

Vidulk’s free AI clipper app (iOS and Android) automates the process:

Open the Vidulk app and upload your Discord recording.
The AI analyzes your video and selects the best moments for short clips.
Export your clips in vertical (9:16) or 4:5 format, ready for LinkedIn’s supported aspect ratios.
Vidulk adds captions to your clips, making them accessible and engaging for LinkedIn’s feed.

4. Upload to LinkedIn

On LinkedIn, start a post, choose your clipped video, and enable auto captions if desired. LinkedIn may take time to process captions, so pre-captioned clips from Vidulk can help your content stand out immediately.

Review LinkedIn’s video preview before posting to confirm sizing and captions display correctly.

Vidulk's AI clipper (free to start, iOS + Android) finds the best moments in a long video and exports captioned vertical clips sized for the destination.
