Video codecs explained: H.264 vs H.265
A codec is what squeezes your video down so it can travel over mobile data. Here is what H.264 and H.265 are, in plain English, and how to pick the right one for your IRL stream.
What a codec does
A codec compresses your video so it can be sent over the internet, then decompresses it again for your viewers. Raw video is far too heavy to stream as is, so the codec does the work of shrinking it down to fit the connection you have.
The better a codec compresses, the more quality you keep for the same amount of data. That is the whole game, and it is why the codec you choose matters when you are out on mobile data.
H.264, the universal one
H.264, also called AVC, is the long-standing standard. It is supported almost everywhere, by every platform and just about every device that plays video. If you send an H.264 stream, you can be confident the other end will understand it.
It is reliable and safe, and that is exactly its appeal. The only downside is that it is less efficient than newer codecs, so it needs a bit more data to reach the same quality.
H.265, the efficient one
H.265, also called HEVC, is the newer option. It delivers roughly the same quality at a lower bitrate, which makes it great for saving mobile data or getting a cleaner picture at the same bitrate you were already using.
The catch is compatibility. Not every streaming platform accepts H.265 for ingest, and it asks a little more of your phone to encode. So the efficiency is real, but it only helps where your destination can actually take it.
Which to pick for IRL
- If your destination supports it, H.265 gives you more quality per megabit, which is ideal when you are on mobile data.
- If you are unsure, or your platform does not accept H.265, H.264 is the safe choice that always works.
For most IRL streamers, that decision comes down to one question: does the platform you are sending to accept H.265? If yes, take the efficiency. If no, stay on H.264 and stream with confidence.
Choosing it in the app
In Super Simple IRL Advanced settings you can switch between H.264 and H.265. There is no need to overthink it.
- Try H.265 first for the efficiency, especially if you are watching your data.
- Fall back to H.264 if your destination does not accept H.265.
If your stream reaches the platform and looks right, you have picked the correct one. If the platform rejects the feed, switch to H.264 and you will be back up. To understand how the codec ties into the numbers you set, see what is bitrate.
Frequently asked questions
What is the difference between H.264 and H.265?
H.264 is the older, universal standard that plays everywhere. H.265 is newer and roughly matches the same quality at a lower bitrate, so it saves data or looks cleaner at the same bitrate. The trade is that H.265 is not accepted everywhere and asks a little more of your phone.
Is H.265 better than H.264?
H.265 is more efficient, meaning more quality for the same data, which is great on mobile. But better only helps if your destination accepts it. Where support is missing, H.264 is the better choice because it always works.
Which codec should I use for IRL streaming?
If your platform supports H.265, use it for more quality per megabit on mobile data. If you are unsure or it is not accepted, use H.264, the safe option that works everywhere.
Does my platform support H.265?
It depends on the platform. Many accept H.264 for ingest but not H.265. Check your destination's ingest settings, and if in doubt, start with H.264 and switch to H.265 only once you confirm it is accepted.
