Stream and record together

Stream and record together, without tying them together

LectureGo encodes the final program as H.264 + AAC and publishes it over RTMP or RTMPS. Streaming and local recording start independently, while scene changes and layer adjustments stay synchronized across both outputs.

  • Defaults to 1080p, 30 fps, H.264 at 6 Mbps and AAC at 128 kbps
  • Automatically reconnects after a server interruption without restarting the app
  • Stores the stream key in macOS Keychain and keeps it out of logs

Complete post-production freedom

Deliver the program now. Refine every track later.

The mixed video is ready for immediate delivery, while isolated tracks preserve every option for the final cut. Reframe, color or replace each picture independently, and denoise, mix or adjust every sound source on its own.

  • Each video source is saved as an ISO file, untouched by the program layout
  • System audio and every microphone are recorded as separate audio tracks
  • Media, tracks and recording markers are placed into a Resolve timeline

From lecture to delivery

Configure less. Teach more.

Stop stitching together capture, production, and timeline tools. Connect sources, go live, and preserve every post-production asset in one workspace.

Multi-source input, affordable multicam

Connect screens, windows, cameras, RTMP and microphones, then use the Android companion to turn multiple phones you already own into wireless angles.

Live scene composition

Move, resize, reorder and lock layers, or apply full-screen, picture-in-picture and split-screen layouts.

Program and ISO recording

Capture the mixed program, every video ISO and every isolated audio track in one synchronized session.

Ready for the full edit

Export DaVinci Resolve XML and OTIO multi-track timelines with aligned media, tracks and recording markers.

LectureGo or OBS?

Choose OBS for a universal studio. Choose LectureGo for a complete course.

OBS is a powerful, open production platform for recording and streaming. LectureGo builds the deliverables course creators need into the default workflow. The best choice depends on what you need when the session ends.

What matters
LectureGoCourse production workspace
OBS StudioUniversal streaming and recording
Core workflow Designed around course ingest, direction, streaming, isolated capture, and delivery A general platform for streaming, recording, and many production scenarios
Video media Per-source ISO built in: save the program and every video source together The standard workflow records the composed output; plugins and scripts can extend it
Audio for post Source becomes file: system and microphone audio are named and saved separately Advanced Output supports up to six recording tracks with manual source assignment
Editing handoff Automatic: Resolve XML / OTIO timeline, aligned media, markers, and report Outputs recording files; build the post workflow around your formats, plugins, and editor
Best fit Teachers, trainers, knowledge creators, and teams that repeatedly edit courses Creators who need cross-platform use, complex overlays, game capture, or deep customization

OBS continues to evolve through releases, plugins, and scripts. This comparison is based on its official product page, overview guide, and multi-track audio guide, and is intended only to help you choose a workflow.

Tutorial

Record and stream a course in six steps

Follow the workflow from connecting sources and going live to opening the complete multi-track edit in DaVinci Resolve.

  1. 01

    Add recording sources

    Select Add in the Sources panel, then choose a screen, window, camera, mobile device, external RTMP stream or microphone. Keep an Android device on the same local network as the Mac for discovery.

  2. 02

    Add sources to the output scene

    Add the required video sources as output layers. Move and resize them freely, or apply a full-screen, picture-in-picture or split-screen layout.

  3. 03

    Enable isolated recording

    Turn on isolated recording for each video or audio source. The scene layout only affects the mixed program and never crops the original source files.

  4. 04

    Configure recording and streaming

    Choose the program orientation, resolution and codec. For a live session, add the RTMP/RTMPS server and stream key. Streaming defaults to 1080p at 30 fps.

  5. 05

    Start streaming and recording

    Start Streaming and Start Recording are independent controls. Run either output by itself or use both together. Streaming reconnects automatically after an interruption.

  6. 06

    Import into DaVinci Resolve

    After recording, choose File → Import → Timeline in Resolve. Use Lecture.xml with Resolve 18.1–18.4, or prefer Lecture.otio with Resolve 18.5 and later.

Recording output Mixed program + video ISO files + separate audio tracks + Resolve timeline + recording report
