Framecast - In-Editor Video and Screenshots

Framecast is a self-contained, professional in-Editor capture tool for Unity. Record clean gameplay, trailers, tool previews, demo clips, tutorials and visual-development progress as video, or grab matching still images, directly from the Editor, with production-grade codecs that most capture tools do not offer.

Open the window from Tools > Decanter Studio > Framecast, choose the Game View or a specific Camera (or the Scene view for stills), set your resolution, then record video or capture a single still. Video recording runs during Play Mode and encodes through FFmpeg. Screenshot capture writes PNG/JPG files through Unity's built-in image encoders and does not require FFmpeg.

What sets Framecast apart

• True alpha video with Apple ProRes 4444 / 4444 XQ, so you can export footage with transparency for compositing, not just opaque clips.
• Hardware-accelerated encoding with NVIDIA NVENC for H.264 and H.265, alongside software H.264/H.265, ProRes and VP8/VP9 WebM.
• Synced audio captured and muxed into the final file (transcoded to Opus for WebM), not a silent screen grab.
• Frame-accurate timing: Constant FPS for deterministic, drop-free capture paced to real time, or Variable FPS to record real-time playback up to a chosen maximum. Either way the file stays in sync and plays back at the right speed.
• Editor scripting API to start/stop recordings and capture screenshots from your own tools and automation.
• Quality control: choose H.264 quality presets or set an explicit custom bitrate in kbit/s.

Main features

• Export H.264 and H.265 video, including NVENC hardware encoding where supported.
• Export Apple ProRes, including ProRes 4444 / 4444 XQ for alpha workflows.
• Export VP8 / VP9 WebM files.
• Record video with synced audio during Play Mode in the Editor.
• Capture the Game View or a selected Camera, plus the editor's Scene view as a screenshot source.
• Capture single-frame screenshots as PNG (with optional alpha) or JPG (with adjustable quality).
• Capture a burst of stills in one action, spaced by a configurable interval.
• Capture Camera and Scene view screenshots in Edit Mode on Built-in, URP, and HDRP, and let Game View screenshots requested from Edit Mode briefly enter Play Mode and return automatically.
• Choose fixed presets, Match Window, or Custom resolution.
• Apply one-click buyer-facing size presets for store listings and social platforms (Unity Asset Store, Steam, App Store, Google Play, YouTube), filtered to the current capture mode.
• Use Constant FPS for deterministic, drop-free frame capture, or Variable FPS for real-time gameplay up to a chosen maximum frame rate.
• Configure quality presets or custom bitrates for H.264 codecs.
• Drive recording and screenshots from code through the Editor scripting API.
• Monitor elapsed time, captured frames, file size, and bitrate while recording.

Capture sources

Framecast can record or screenshot the active Game View or a chosen Camera, and can also screenshot the editor's Scene view. This makes it suitable for quick gameplay captures, controlled camera shots, Scene-view angles for level-design and marketing stills, UI demos, visual effect previews, repeatable marketing clips, and still images for store pages, documentation, or progress notes.

Video recording

Record mode captures video with synced audio during Play Mode. Pressing Record from Edit Mode enters Play Mode and starts automatically. Constant FPS drives Unity's capture timing so every frame is captured at the selected rate, paced to the wall clock so the clip stays real-time. Variable FPS records real-time playback up to the chosen maximum frame rate, which is useful when you want the capture to reflect actual Editor playback. Audio is captured and muxed into the final file on stop.

Screenshot capture

Screenshot mode saves a single still of the Game View, a Camera, or the editor's Scene view using the Capture and Output settings, with no FFmpeg required. Camera and Scene view stills are written directly in Edit Mode on the Built-in, URP, and HDRP render pipelines, without entering Play Mode. PNG is lossless and can include alpha; JPG is smaller and exposes a quality slider. Enable Burst to capture a series of stills in one press, spaced by an interval. The Screenshot controls remain available while a video recording is running, so you can grab stills mid-capture.

Developer scripting API

Editor scripts can drive Framecast through a public API: start and stop recordings, capture screenshots, read live capture state, and preview output file names. This makes it easy to wire capture into your own editor tools, menu items, and automated workflows.

FFmpeg setup

FFmpeg is required for video encoding and is not bundled with the package. Download ffmpeg.exe manually and place it in the package's Editor/FFmpeg folder, or, if you already have an ffmpeg.exe, point Framecast at it with the browse (...) button. The FFmpeg card includes Download, Open folder, and Auto-detect helpers. Screenshots do not require FFmpeg. See Third Party Notices.md in the package for FFmpeg licensing details.

Requirements

• Unity 2022.3 LTS or newer.
• Windows only.
• FFmpeg is required for video encoding and must be supplied separately; screenshots do not require FFmpeg.
