OBS is a powerful general-purpose recording tool. PixelRec is designed specifically around creating Photoshop art timelapses. Both can support an artist's content workflow, but they solve different jobs.
Choose OBS when the screen, voice, camera, or live broadcast is part of the content. Choose PixelRec when the artwork's progress is the content.
OBS combines display or window capture, webcams, audio, images, and other sources into reusable scenes that can be recorded or streamed.
PixelRec runs inside Photoshop and focuses on capturing the drawing process, reducing repeated frames, and exporting a clean MP4 timelapse.
A fair note about OBS: OBS does not have to record an entire display. It can capture a window or cropped source, and saved scenes can be reused. Visible Photoshop controls, cursor movement, zooming, panning, and dialogs remain part of the selected area.
This comparison keeps the strengths and limits of both workflows visible.
| Topic | OBS Studio | PixelRec |
|---|---|---|
| Purpose | General recording and live-stream production. | Photoshop art timelapses and speedpaints. |
| Initial setup | Create or reuse a scene, add a display or window source, position or crop it, and choose video, audio, and output settings. | Install once and choose your preferences. There is no recording setup to rebuild for each Photoshop session. |
| Repeat sessions | Saved scenes and sources can be reused; confirm the source and start recording or use a hotkey. | Starts capturing automatically when you open or work on a Photoshop project. There is no Start button. |
| Photoshop UI | Anything inside the selected source or crop is recorded, including visible Photoshop controls. | The recording is artwork-focused rather than a capture of the full Photoshop interface or desktop. |
| Recording workflow | Records continuous video until it is paused or stopped. | Captures the art process and saves a frame only when the canvas changes. |
| Idle time | Remains in the video unless recording is paused or the footage is edited later. | A frame is saved only when the canvas changes, so breaks are left out. |
| File workflow | File size depends on duration, resolution, frame rate, bitrate, and encoder settings. | Captured content centers on artwork changes; final size still depends on the session and export settings. |
| Art-specific tools | Flexible capture, but timelapse preparation is a separate production step. | Includes automatic capture, session tracking, frame tracking, and direct timelapse export. |
| Post-processing | A speedpaint usually needs trimming, speeding up, and possibly cropping or reframing. | You choose the video length at export, so a separate speed-up pass is not needed. |
| Output control | Broad control over formats, encoders, resolution, frame rate, and audio. | MP4 in 720p, 1080p, 1440p or 4K, as a 15, 30 or 60 second video, or the full length, in several sizes at once. |
| Audio and streaming | Built for microphone, webcam, multi-source scenes, and live streaming. | Published features focus on artwork capture and timelapse export. |
| Best use | Tutorials, livestreams, commentary, interface demonstrations, and complex scenes. | Drawing-process videos, speedpaints, social posts, and portfolio timelapses. |
OBS is the better fit when the recording needs to show or combine more than the artwork.
PixelRec is the better fit when your main goal is a Photoshop art timelapse.
Artists can use both. PixelRec can preserve a clean artwork timelapse while OBS handles a separate livestream or narrated tutorial. Choose each tool for the output it was designed to produce.
Open the Photoshop document and start drawing. PixelRec captures automatically without a per-session setup or Start click; when you finish, choose the video length and size, then export an MP4.
If you want an artwork-focused timelapse rather than a full recording production, PixelRec can capture your Photoshop process automatically and export a share-ready MP4.
