Questions, answered straight.

What people ask before they trade OBS for something new. Where the honest answer is "not yet" or "we have not tested that", it says so.

The basics

What is BriseStream?

BriseStream is a free, open-source (GPL-3.0-or-later) streaming and recording application for PC, built to replace OBS Studio while being far smaller to download and cheaper on the game. It is in development: version 1.0 is in preparation.

Is BriseStream free?

Yes, free and open source under GPL-3.0-or-later, with no account needed. The only paid thing is the optional custom overlay pack from the studio, at €19.

When can I download it?

Version 1.0 is in preparation and there is no public build yet. The download page explains how to be told the day the first build ships.

Which systems does it run on?

Windows first. Linux and macOS come after, with no date. The virtual camera needs Windows 11.

Which graphics cards work?

Cards with a video encoder: NVIDIA (NVENC), AMD (AMF) and Intel (QuickSync). If your card has none, a software H.264 fallback uses your processor and tells you so.

Performance

Is it really lighter than OBS?

The installer is about 17 times smaller (10.6 MB against 186.7 MB for OBS Studio 33.0.1). On your game, in the runs where we measured both on one GPU, BriseStream cost less than OBS, but our 1 % target is not met on every setup. The numbers, with their conditions.

How many FPS will I lose?

We cannot promise a number. It depends on the game, the card and the settings, and our measurements range from within noise to about 17 % on one demanding case. Run the same test on your own game once 1.0 is out.

Why does it not hook into the game like OBS game capture?

Hooks depend on each game and have caused black screens under anti-cheat systems. BriseStream captures through the operating system and injects nothing. That costs some FPS, and it is the largest single cost we found; we accept it on purpose.

Does it work with anti-cheat games?

Nothing is injected, which is what such systems object to. We have not tested exclusive full screen or specific anti-cheat games yet, so we do not claim it works.

How is lightness measured?

With measurement tools that ship in the source code: the FPS of a game with and without recording, timed frame by frame, plus the pictures actually kept in the file, memory and GPU load.

Coming from OBS

Can I keep my OBS scenes?

Yes. Settings, Import converts your scene collections and profiles, and lists what could not be converted and why. How the import works.

Will my Stream Deck keep working?

BriseStream has a local API that speaks obs-websocket 5, the protocol used by tools written for OBS. It is off by default. We have not tested every Stream Deck plug-in, so try yours first.

Do my OBS plug-ins work?

No. OBS plug-ins are not compatible. BriseStream has its own stable plug-in interface, and it hosts VST3 audio plug-ins in a separate process.

What is missing compared with OBS?

Linux and macOS for now, the plug-in ecosystem, audio-only recording, some file formats and named streaming services, among others. The full list is on the features page.

Recording and streaming

Is my recording safe if the PC crashes?

The file is written as a Matroska file as it goes, so a crash or power cut leaves a file you can play. After you stop, it is converted to MP4 off the interface thread, and the original is kept by default.

Can I stream to Twitch and YouTube at once?

Yes, with Kick and any custom server too. Each destination has its own statistics and switch, and one failing does not stop the others or your recording.

Which codecs are supported?

H.264, HEVC and AV1 on your graphics card's hardware encoder. Twitch and Kick only accept H.264; YouTube and your own server can take HEVC or AV1.

Can I make vertical video for short-form platforms?

Yes. A second, vertical canvas is encoded on its own, so a recording or a stream can pick it. The second encoder only runs while it is used.

Overlays and the studio

What overlays come with the app?

Ten ready-made packs in 33 looks, each with six scenes: opening, game, talking, break, ending and alerts. See them.

What is the custom pack, and what does it cost?

It is a pack designed for your channel by an AI designer, in a dialogue with you: six screens including alerts, several rounds of changes, delivered into BriseStream. It costs €19, once, and it is optional.

Do I need the custom pack to use BriseStream?

No. The app is complete and free without it.

Privacy and the project

Does BriseStream send my data anywhere?

Nothing is sent unless you ask. The update check is off until you turn it on, and it only downloads one small file.

Where are my stream keys kept?

In the Windows Credential Manager, not in the settings file.
