Simplified workflow for HLS-Streaming

MP4 or HLS? What Works Best for Video on Your Website

Websites are becoming more and more video-heavy – whether it’s product demos, explainer videos, customer testimonials, or event streams. And that brings up a crucial technical question: how do you actually embed videos on your site?

  • Do you just upload a simple MP4 file?
  • Do you (like almost everyone else) default to YouTube?
  • Or do you go the professional route with HLS (HTTP Live Streaming)?

In this article, you'll learn:

  • What MP4 is – and what it can (and can’t) do
  • How HLS works – and why it’s the better choice in most cases
  • How to create your own HLS files – with tools and practical steps
  • And: how Ignite takes care of the hard parts for you

Let’s dive in 👇

Why is this even a question:
HLS or MP4?

When it comes to embedding video on your website, you’ve got a few options:

  • Upload an MP4 file
  • Use YouTube (yes, a lot of people still do)
  • Or go for a professional setup with HLS

The tech behind your video matters more than you might think:

  • MP4 seems simple – but it doesn’t meet modern demands very well.
  • HLS is faster, more stable, and scalable – but more complex to set up.

So your choice has big implications for things like:

  • Loading times
  • Quality on slow connections
  • User experience across devices
  • Scalability when traffic spikes
  • And yes – even your Google ranking

Basics: What is an MP4 file?

MP4 is a so-called container format. It can include video, audio, subtitles, and metadata – and it plays on pretty much every device. On websites, it’s usually paired with the HTML5 <video> tag.

So basically... it’s just a video file.

Advantages:

  • Simple to use
  • Widely supported by browsers and devices
  • No extra infrastructure required

Disadvantages:

  • The full file has to be downloaded, in a single quality
  • No adaptive quality for slow connections
  • Can cause performance issues with multiple users
  • One of the biggest problems: web servers.

“A single HD or 4K stream can require several megabits per second. If many users access the video at the same time, this multiplies quickly. Most web hosting plans aren’t built for that – they often promise 'unlimited traffic', but in reality there are technical or contractual limits, especially around continuous data transfer.” - Marco Keul, Hosttest.de

Basics again: What is HLS streaming?

“HTTP Live Streaming (HLS) is an HTTP-based adaptive bitrate streaming communications protocol implemented by Apple Inc. It allows streaming of audio and video content over the internet.”

Wikipedia: HTTP Live Streaming

HLS stands for HTTP Live Streaming – a streaming protocol developed by Apple. Instead of one big file, your video is split into small segments and multiple quality levels. The video player chooses the best version for each user in real time.

“Support for the protocol is widespread in media players, web browsers, mobile devices … it is the most popular streaming format.”

– Wikipedia

How HLS Streams work. From the input video, to encoding process (.m3u8 + .ts files) and the streaming server.

Benefits of HLS streaming for websites

Better user experience

Thanks to segmentation and adaptive bitrate, videos start faster and run smoother – even on slow or unstable connections.

“HLS: Segmented video is played in sections. Therefore, the launch occurs almost without freezes.” - Movavi

Optimized quality on every device

Whether someone is watching on a 10-year-old phone or a high-end desktop, HLS delivers the right version for the situation.

Scalability without stress

Even if hundreds of people watch your video at once, HLS stays stable – only small segments are transferred instead of full files.

Compatibility across the web

HLS works over HTTP/HTTPS, plays well with firewalls, and is the native format on Apple devices – something DASH can’t say.

Downsides of HLS

Yep... it’s definitely more effort. You’re not just uploading one file – you're building a full streaming setup.

Technical complexity

You’ll need tools to transcode, segment, and generate manifest files. And you’ll need a compatible player.

Infrastructure requirements

Uploading a single file isn’t enough. You need proper hosting that supports segment delivery and streaming protocols.

HLS Streams vs. MP4 Files - how the different streaming technologies work. In this case shown for a user with bandwitch problems.

Why HLS is usually the better choice

Even if MP4 looks easier at first glance, HLS is almost always the smarter solution – especially for modern websites.

1. Better streaming experience

HLS streams your video in segments. That means faster start times, less buffering, and smoother playback – especially on mobile or under weak network conditions.

2. Lower bandwidth, lower cost

HLS only delivers what the user actually watches – not the entire file. That saves bandwidth on both your server and the user side. This is only true at a certain point of video views. Small websites typically use webspace with included traffic. This leads to point 3 ...

3. It scales – even when traffic spikes

If for example your newsletter or launch drives traffic to a video, MP4 downloads can bring servers to their knees. HLS works with CDNs and caching to handle the load.

Standard web hosting plans are usually designed for websites with text and images – small files and low data usage. Uploading large video files can quickly become a problem: performance drops, load times increase, or technical limitations kick in, like bandwidth throttling or missing support for adaptive formats like HLS.” - Marco Keul - Hosttest.de

4. Future-proof tech

More and more browsers and platforms expect adaptive formats. MP4 alone starts to feel outdated. HLS is the market standard – and here to stay.

So if you're embedding more than just one video or want professional delivery, HLS is the way to go.

Step-by-step: How to create HLS files

Yes, it sounds technical – and it is. But here’s a simplified, practical overview of what’s involved in getting HLS up and running:

1. Prepare your source video

Start with the best-quality version of your file – ideally MP4, ProRes, or MOV.

2. Choose a transcoding tool

The most popular open-source tool is ffmpeg. It can convert videos to multiple bitrates and segment them at the same time.

3. Create bitrate variants

Set up multiple resolutions like 360p, 720p, and 1080p – or more, depending on your audience.

4. Segment the video and create a manifest

Your tool will generate many small .ts (or fMP4) files and one .m3u8 playlist – this is what your player uses to stream.

5. Set up hosting

You’ll need a web server or CDN that delivers these files properly – with CORS headers, correct MIME types, and HTTPS support.

In short: yep, it's a lot.

No surprise professional video hosts exist for exactly this kind of job.

But the effort is worth it – especially if your site includes multiple videos and you care about performance, scalability, and quality.
