Use a DSLR or mirrorless camera for live streaming

Stream with a DSLR, mirrorless camera or camcorder from the browser studio, through an HDMI capture card or the maker's USB webcam mode, and the settings that matter.

Updated November 5, 2026 · 4 min read

A DSLR, mirrorless camera or camcorder reaches the browser studio in one of two ways, and both end the same way: the browser sees a camera, and you pick it in the studio like a webcam. The first way is HDMI into a USB capture card. The second is the camera maker's own webcam mode over USB, when your model has one. After that the camera is a tile you put on air and send to every network at once.

Which way to choose

Before you start

• Clean HDMI output (capture card path). The camera must send the picture without its menus, focus marks and battery icon on top, or viewers see them too. The setting has different names per maker and model; look in the HDMI or display part of the camera's menu. Elgato keeps a list of cameras and notes on clean HDMI for its Cam Link 4K: Cam Link 4K, is it suitable for you (checked 5 November 2026).
• The camera does not switch itself off. Many cameras have auto power-off and a limit on how long they keep recording. Turn auto power-off off in the camera's menu, and check in the camera's manual whether HDMI output keeps running without a time limit.
• Power for a long live. A battery may not last a whole broadcast. Many makers sell a mains adapter for their cameras; check what fits your model.
• The maker's webcam software (USB path). Canon offers EOS Webcam Utility (Canon: EOS Webcam Utility, checked 5 November 2026). Sony describes its webcam options, including Imaging Edge Webcam and USB streaming on some models (Sony support article on webcam options, checked 5 November 2026). Which models are supported, and whether the mode carries sound, is decided by the maker; check their page for your camera.
• The browser studio is open. Choose Live stream, start a new live and pick Browser Studio.

Steps

1. Set up the camera. Video mode, auto power-off off, clean HDMI on (capture card path) or the maker's webcam mode on (USB path). Mount it on a tripod and frame the shot.
2. Connect it to the computer. HDMI to the capture card and the card to a USB port on the computer, or the camera's USB cable straight to the computer.
3. Close other programs that use cameras. The maker's webcam software may need to stay open; close everything else that shows the camera.
4. Open the camera window. In the bar under the picture open Add input and press Camera, or click the Add camera tile. If you plugged the camera in just now, press Refresh.
5. Pick the camera. Choose the capture card, or the name the maker's software gives the camera, in the Camera list.
6. Pick the sound. In the Microphone list choose the capture card's audio device if the camera's microphone goes over HDMI, or a separate microphone near the speaker. Choose No microphone if the sound comes from another tile.
7. Press Add and check the picture. Click the tile to put it on Preview. If the camera's screen icons show up in the picture, clean HDMI is not on yet.
8. Take it to air and go live. Press Take or Cut (Preview, Program, Take and Cut explained), then start the live to your networks: How to live stream to several platforms at once.

Settings that make the biggest difference

• Lock exposure and white balance in the camera. Faces then do not pulse brighter and darker during the live.
• Use continuous autofocus with face tracking, or manual focus if the speaker does not move.
• Match frame rates. The studio asks for 30 frames per second. A camera set to 30 (or 25 in countries that use 50 Hz power) avoids uneven motion.
• Keep the sound close to the speaker. The microphone on top of a camera hears the room. A lavalier or a USB microphone near the mouth usually sounds better: Sound in the browser studio: levels, mute and noise filter.

What can go wrong

• Black tile. Clean HDMI is off and the camera sends nothing, the camera went to sleep, or the card is held by another program: My capture card shows a black screen or has no sound.
• The camera's menus are on air. Turn on clean HDMI output, or switch the camera's display mode until the screen shows only the picture.
• The picture stops after a while. Auto power-off or a recording time limit in the camera. Check the camera's menu and manual.
• Sound a little behind the picture. The picture and the sound come from different devices. Use the card's own sound when the camera has the microphone, see My capture card shows a black screen or has no sound.
• Low resolution. The camera's webcam mode may send less than HDMI. See My camera picture is low resolution in the studio.

Frequently asked questions

Can I live stream with a DSLR without a capture card?

Yes, if the camera maker offers a USB webcam mode for your model. The camera then shows up in the browser's camera list. Otherwise use HDMI and a capture card.

Does StreamLive Pro recommend a camera?

No. We do not test or recommend camera models. If the camera reaches the browser as a camera, the studio can use it.

Will my camera's microphone work?

Through a capture card, yes, when the camera sends sound over HDMI and you pick the card's audio device. With a USB webcam mode it depends on the maker.

Can I use a DSLR and a webcam together?

Yes. Each one is its own tile in the studio, and you switch between them with Preview and Take.

Why does the camera turn off in the middle of a live?

Most often auto power-off, overheating or a time limit on recording. Turn auto power-off off and use mains power for long broadcasts.
