Post-Production and Color Correction for Game Video
The render from the engine is ready. The ProRes file looks fine in Media Player, but after uploading to YouTube the video becomes dull, contrast drops, and bright UI elements blow out. This is not a YouTube bug — it's incorrect color space management at every pipeline stage. We work with Unity and Unreal Engine, and every fifth submission contains this error. Even correctly configured export to ProRes doesn't guarantee identical display — YouTube re-encodes to VP9, and color metadata can be lost.
Post-production of game video is not 'add music and subtitles'. It's color management, editing with target platforms in mind, and technically correct final export. Our experience: over 50 completed trailers and teasers. We guarantee your video will look equally good on YouTube, Steam, and social media. Without professional post-production, videos lose up to 30% contrast and saturation on mobile devices, leading to lost views.
How to Set Up Color Space for YouTube?
Step-by-step guide for color space setup in After Effects
- Open
Edit > Project Settings > Color Settings. Set the working space toRec. 709 Linearif the material was tone-mapped from HDRP, orACES CG Linearfor HDR sources. - For each clip: right-click →
Interpret Footage→Color Profile. Explicitly specifyRec. 709 (sRGB)if the original render was in sRGB, orRec. 2020if HDR. - Add an Adjustment Layer to the composition with the
Lumetri Coloreffect. Perform primary correction: white balance by neutral zones, exposure, contrast. - For final render:
Composition > Add to Render Queue→ Output Module → selectLossless(ProRes 4444) orH.264with profileRec. 709. - Upload to YouTube at maximum resolution (4K) — this activates the VP9 codec and improves streaming quality.
The error in the first step is the most expensive: if After Effects applies sRGB gamma to Linear data, the image appears 'washed out'. We set up profiles at the preview stage so you see the final result before rendering.
Why Color Space Is the Main Technical Trap
Unity renders in Linear gamma with ACES Tonemapping (if HDRP). When exporting via Recorder to ProRes 4444 or EXR, you get HDR data in a wide range. Import into After Effects: if the project is set to sRGB, After Effects automatically applies a gamma curve — and the image changes.
Correct workflow:
- After Effects project: working space
ACES CG LinearorRec. 2020 Linearwhen working with HDR material. - Or
Rec. 709if the material is already tone-mapped from HDRP. - Interpretation of each footage file explicitly — right-click on clip →
Interpret Footage→Color Profile. - Final render with Output Profile =
Rec. 709 (sRGB for SDR distribution)orRec. 2020 PQfor HDR mastering.
Ignoring these settings creates subtle artifacts that are hard to describe but immediately visible: overly bright shadows, blown highlights, unnatural contrast. The ACES CG Linear working space is the industry standard for HDR material. For more details, see Rec. 709.
Color Correction and Color Grading
Color correction is technical balancing (removing unwanted tints, adjusting exposure between shots). Color grading is artistic (setting mood via LUTs and curves).
For game content, the standard approach: primary correction through Lumetri Color in Premiere or Color Finesse in After Effects — balance by skin tones if present, by neutral environment zones. Then LUT for style — create a custom one in DaVinci Resolve or use a library as a starting point.
DaVinci Resolve is a professional tool for color work with game video. Node-based color graph: Input Transform → Primary Correction → Creative Grade → Output Transform. For gamedev content, the Qualifier for secondary correction is especially important: you can separately increase saturation of only the blue sky or raise contrast only in shadows without touching highlights. In DaVinci Resolve for secondary correction we use Qualifier: select a color range (e.g., sky blue) and apply separate corrections — increase saturation, change hue, add contrast. This preserves environment realism while accentuating key elements.
Why Proper Export Matters
Even a perfectly shot and edited trailer will be ruined by the wrong codec or bitrate. Each platform has its own requirements — ignoring them leads to loss of detail, banding, and compression artifacts.
Technical Export by Platform
| Platform | Codec | Resolution | Bitrate |
|---|---|---|---|
| YouTube | H.264 / VP9 | 3840×2160 (4K preferred) | 40-68 Mbps |
| App Store Preview | H.264 | 1320×2868 (iPhone) | 30 Mbps |
| Instagram Reels | H.264 | 1080×1920 | 8-10 Mbps |
| Steam Trailer | WebM / H.264 | 1920×1080 min. | 15-20 Mbps |
YouTube re-encodes everything on its side — it's best to upload 4K even for 1080p content, because 4K videos use the VP9 codec with better streaming quality. To simplify work, we create export presets for each platform: YouTube (4K, H.264, 40-68 Mbps), Instagram Reels (1080×1920, H.264, 10 Mbps), Steam (WebM, VP9, 20 Mbps). This eliminates errors during final render.
Typical Post-Production Mistakes for Game Video
- Incorrect color profile interpretation — the most common. Ignoring Linear vs sRGB leads to 'washed out' images.
- Using standard LUTs without adaptation to specific material. Each project requires custom curve adjustments.
- Exporting to H.264 with low bitrate — artifacts and macroblocks appear. For quality video, use ProRes or DNxHR at intermediate stages.
- Neglecting subtitles — in social media, videos are often watched without sound. Animated subtitles increase engagement.
What's Included in Turnkey Work
- Primary color correction and exposure balancing across all shots
- Artistic color grading with custom LUTs or stylization based on references
- Trailer editing with narrative structure and synchronization with music
- Creation of stylized animated subtitles (mandatory for social media)
- Export in 4K+ versions for YouTube, Steam, App Store, Instagram Reels
- Final file in ProRes 4444 for archive and reuse

Timeframes
| Scope of Work | Timeline |
|---|---|
| Color correction of finished video (up to 2 min) | 1–3 days |
| Trailer editing (30-60 sec) from existing material | 3–7 days |
| Full post-production (editing + grading + sound + export) | 1–3 weeks |
