Best Encoding Settings for 24/7 Streaming (H.264 & AAC)
The right export settings make a 24/7 stream look sharp and run stable. Here are the best encoding settings for always-on streaming — codecs, container, bitrate and more.
For a 24/7 channel, encoding is where quality and stability are decided. Get your export settings right and playback stays smooth for weeks on end; get them wrong and you invite artifacts or compatibility issues. The good news is that the ideal settings are well-established and easy to match.
Here are the best encoding settings for always-on streaming.
Key takeaways
- Export MP4 with H.264 video and AAC audio — the streaming standard.
- A 2-second keyframe interval suits live delivery.
- Match bitrate to resolution: ~4,500 kbps for 1080p30.
- Pre-encoding in the cloud keeps every clip's profile consistent.
Container and codecs
Use an MP4 container with H.264 video and AAC audio. This combination is what every major platform expects and plays back most reliably. H.264 offers the best balance of quality, file size and compatibility, and AAC is the standard live audio codec. Other formats (MOV, MKV, WebM) can work, but MP4/H.264/AAC is the safe default.
Resolution and frame rate
Pick what your content needs. 1080p at 30 FPS is the sweet spot for most channels — crisp, efficient, and widely supported. Use 60 FPS only for fast motion like gaming, since it needs more bitrate. Keep every video in the playlist at the same resolution and frame rate so the feed doesn't shift as clips change.
Bitrate
Match the platform's recommendation: roughly 4,500 kbps for 1080p30, and around 6,000 kbps for 1080p60. Higher isn't better if it exceeds what the platform accepts. For audio, AAC at 128–192 kbps stereo is ideal. A cloud service auto-selects a suitable bitrate, so you don't have to.
Keyframe interval and profile
Set a keyframe (GOP) interval of about 2 seconds, which platforms use to segment the stream. The H.264 High profile gives good quality at a given bitrate. These are export details rather than things you tweak per stream — set them once in your editor's export preset and reuse it.
Let pre-encoding handle consistency
The biggest reliability win for 24/7 is consistency across clips. With StreamHouse, uploaded videos are prepared with a consistent encode profile, so every clip in the loop streams at a steady bitrate with no jarring shifts. There's no real-time transcoding to bottleneck, which is why pre-encoded channels look smooth around the clock.
Frequently asked questions
What's the best format to upload for streaming?
MP4 with H.264 video and AAC audio. It's the most compatible and reliable combination for live delivery.
What keyframe interval should I use?
About 2 seconds. This aligns with how streaming platforms segment a live feed.
Do I have to set these myself?
Only in your editor's export. Once uploaded, StreamHouse handles streaming-side encoding and bitrate automatically.
Can I upload MOV or MKV files?
Yes — MOV, MKV, WebM and M4V are supported. For the most reliable results, export to MP4 with H.264 video and AAC audio in a single container.
