Code reviews are where collaboration meets clarity. But sometimes, even the best-written comments can’t fully explain why a change was made or how a new feature behaves.

That’s where video comes in – short clips embedded in GitHub Pull Requests (PRs) can save hours of back-and-forth discussion and help teams review code visually.

According to GitHub Octoverse 2024 insights, repositories that include video content in their collaboration workflows – such as issues, pull requests, or documentation – experience higher engagement and faster merge cycles. Adding video to your PRs brings a human touch to async communication, especially for remote or open-source teams.

Why Add a Video to a Pull Request

Pull Requests are often filled with complex context: architecture changes, UI updates, performance improvements, or behavior tweaks that are easier seen than described.

By embedding a short video in your PR, you can:

– Demonstrate how a feature works visually

– Showcase UI or animation changes

– Explain your reasoning or architecture decisions

– Reduce misunderstandings in async reviews

– Keep reviewers engaged even in long code discussions

Developers using video-based explanations report measurable productivity benefits. The Stack Overflow Developer Survey 2025 found that teams using video during review or triage reduced average resolution time by about 25%, mainly because reviewers can instantly understand behavior and intent.

How to Add a Video to a GitHub Pull Request

GitHub now natively supports video uploads in comments and descriptions. Here’s how you can do it step-by-step.

1. Upload a video directly

Simply drag and drop an .mp4 or .mov file into your Pull Request description or comment. GitHub automatically embeds it for inline playback.

This is perfect for quick UI demos or animations that accompany a change.

2. Record a video with Videolink

If you want to explain code behavior, show a bug fix, or provide a short walkthrough without leaving GitHub, Videolink makes it instant.

You can record your screen or camera, blur sensitive data, and share the link – no login required.

Once recorded, Videolink generates a secure shareable link such as:

https://govideolink.com/v/your-video-id

Paste this link directly into your PR description or a comment. It will appear as a clickable preview that reviewers can open in one click.

Example: Visual Code Review

Here’s how developers commonly use videos in PRs:

Scenario 1: Front-end developer showcases a new modal window animation.

Scenario 2: Back-end engineer explains the impact of a refactor on API responses.

Scenario 3: QA reviewer shows how a fix behaves in production.

Instead of multiple screenshots and long paragraphs, a 15–30 second video gives full visual clarity.

This makes PRs more engaging, helps new contributors understand your work faster, and significantly reduces repetitive clarifications.

Accessibility and Engagement Benefits

Video adds more than visual clarity – it improves inclusion and attention.

Vimeo’s 2025 engagement study found that short videos achieve up to 80% viewer retention, even for technical topics.

This means reviewers actually watch the whole explanation, unlike text comments that can be skimmed or skipped.

Accessibility also improves through AI-generated transcripts and subtitles, available automatically in Videolink.

The Nielsen Norman Group reported that subtitles enhance understanding for around 85% of users, including non-native speakers and developers with hearing impairments.

For global or distributed teams, this makes async collaboration significantly more inclusive.

5 Practical Use Cases for Video in PRs

1. UI Reviews – Show visual changes like layout, animation, or transitions.
2. Feature Walkthroughs – Demonstrate new functionality before merging.
3. Performance Testing – Display benchmarks or time comparisons.
4. Bug Fix Verification – Record before/after results for quick validation.
5. Team Onboarding – Explain code structure or logic visually for new contributors.

The Future of Pull Requests: Visual and Async

Modern development is shifting toward async collaboration.

Videos in Pull Requests bridge the gap between text discussions and live calls.

They bring empathy, tone, and clarity – helping maintainers and contributors communicate like they’re sitting next to each other, even across time zones.

GitHub’s ongoing investment in native video support makes this workflow even smoother. Combined with Videolink’s instant recording and annotation features, it’s easier than ever to collaborate visually – no extra setup required.

Summary

• You can upload .mp4 and .mov videos directly to GitHub PRs

• Videolink allows instant recording with no login required

• Video reviews reduce bug resolution time by 25%

• Short videos improve attention and retention by 80%

• Subtitles and transcripts increase understanding for 85% of users

Final Tip

If your Pull Request needs a meeting to explain it, record a video instead.

A 30-second walkthrough saves your team multiple review cycles – and with Videolink, you can capture and share directly from GitHub in one click.
