✅ Do:
| Problem | Why It Happens | Solution | |---------|----------------|----------| | Black screen | DRM / hardware acceleration | Disable GPU rendering in browser or use direct show player | | Blurry/pixelated | H.264 compression, low bitrate | Find a better source (Blu-ray, web-dl) | | Jagged lines | Poor deinterlacing | Enable YADIF 2x or use original progressive source | | Wrong colors | Color space mismatch (Rec.709 vs Rec.601) | Set player to BT.709 for HD content | | Duplicate frames | VFR (variable frame rate) | Convert to CFR with FFmpeg before capping | animation screencaps
