Bitrate budgets: matching your encoder to your plan

Bitrate is not a quality dial you can turn up without limit. It is the amount of video and audio data your encoder sends into the stream. More data can help a detailed or fast-moving picture, but sending more than your ApexStream plan accepts can make the connection unstable.

The useful habit is to choose a target below the ceiling, include audio in the math, and keep the same setting in every encoder profile. That gives you a clear answer when the picture looks soft: either the source needs more bitrate, or the plan and output do not match.

The plan ceilings

ApexStream’s ingest caps are total feed limits for video plus audio:

• Free ($0/mo): 3 Mbps, 720p output, and up to 2 destinations.
• Hobby ($25/mo): 6 Mbps, 1080p external output, and up to 3 destinations. Web Studio output is 720p.
• Creator ($60/mo): 9 Mbps, 1080p Web Studio output, an external 4K path, and up to 5 destinations.
• Scale ($199/mo): 15 Mbps and up to 8 simultaneous destinations.
• Enterprise: custom allocations up to 50 Mbps and up to 50 destinations.

These are ceilings, not recommended targets. A plan with a 6 Mbps cap does not require a 6 Mbps output. Leave room for audio and the small amount of protocol overhead that travels with the feed.

Do the three-part calculation

Use this simple check:

Total Encoder Bitrate = Video Bitrate + Audio Bitrate + Protocol Overhead

For a Hobby example, 5,600 kbps of video plus 160 kbps of AAC audio and about 100 kbps of overhead comes to roughly 5,860 kbps. That stays below the 6,000 kbps cap and leaves a small margin. Your actual encoder may report the total differently, so use the ApexStream stream health view when it is available on your plan.

If you are close to the ceiling, reduce the video target rather than hoping the extra packets will be ignored. A stable 5,600 kbps feed is more useful than a feed that repeatedly tries to send more and loses connection.

Use CBR for a predictable feed

Variable bitrate can look attractive because it spends more data on complicated scenes. The problem is that the spikes can push the total above the plan cap even when the average number looks acceptable. Fast gameplay, a detailed screen share, or a busy camera move can expose that difference.

Set the encoder to CBR (Constant Bitrate) for the ApexStream output. CBR keeps the feed closer to the number you chose and makes the connection easier to monitor. It does not fix an undersized plan or a weak local connection, but it removes one source of surprise.

Match the plan to the picture

Choose the plan from the hardest part of your show, not the easiest talking-head segment. A 720p interview with two destinations may fit Free. A fast 1080p program with several destinations needs more room. If your visual content repeatedly needs more than the 6 Mbps Hobby ceiling, Creator’s 9 Mbps cap may be the more practical fit.

This is also where destination count matters. A larger plan can give you more bitrate room and more simultaneous destinations, but it does not remove the need to test each platform’s output. The master feed still has to be steady before it can be distributed.

Check the number during a test

1. Set CBR and choose a video bitrate below the plan cap.
2. Add your audio bitrate and leave a margin for overhead.
3. Run the scenes that create the most motion or detail.
4. Watch the encoder’s dropped-frame indicators and ApexStream stream health on Hobby and above.
5. Lower the target or change the plan if the feed keeps approaching the ceiling.

Bitrate budgeting is not about chasing the largest number. It is about sending a feed your plan and connection can sustain for the whole show.

Save the chosen value with the encoder profile and label it by plan. That makes the next pre-flight faster and prevents a profile built for Creator from being reused on Free by accident. When the production changes from a talking head to fast motion, test that harder scene against the same budget before raising the number.
