# How to 3D map a crash scene with an Autel EVO Max 4T > To 3D map a crash scene with an Autel EVO Max 4T, fly it manually in its native app and record one continuous video, then upload the video to SkyeBrowse. Source: https://www.skyebrowse.com/guides/crash-reconstruction/autel-evo-max-4t ## Capture the crash reconstruction with the EVO Max 4T ### Manual flight The SkyeBrowse Flight App does not support the EVO Max 4T, so fly it in its native app. Record one continuous video while moving around the scene. Keep the camera pointed down at the subject, keep zoom locked, move smoothly, avoid excess sky, and finish with overlap where you started. ### Georeference the model Turn on .ASS subtitle recording on the Autel aircraft before takeoff. Upload the .ASS file with the video and SkyeBrowse georeferences the model automatically. ### Autel setup tutorial Follow the SkyeBrowse Autel EVO II and Max 4T tutorial to enable .ASS subtitle files for georeferencing. ## Process the video Upload the MP4 or MOV file at app.skyebrowse.com. Processing runs at about one minute per minute of video, and most models are ready 5 to 10 minutes after upload. Public Safety & Enterprise models reach 0.1 inch accuracy and Commercial models reach 0.5 inch, with no ground control points. ## Outputs and measurements for crash reconstruction ### Distance, area, and angle Measure skid marks, vehicle positions, and roadway geometry directly on the 3D model or orthomosaic. ### Crush & Claims Analysis Identify each vehicle, align an undamaged reference model with the damaged scan, and review crush depths, CDC classification, and derived delta-V with stated assumptions. Free on every plan through October 31, 2026, then included with Public Safety & Enterprise models. ### Factual Diagram On Public Safety & Enterprise models, generate a court-ready PDF with a top-down overview, sketch page, annotations, measurements, scale bar, and compass when available. ### Exports Download LAZ, GLB, OBJ, USDZ, GeoTIFF, and CAD files for forensic and CAD software on export-enabled models. ## Frequently asked questions ### Does the SkyeBrowse Flight App support the Autel EVO Max 4T? No. Fly the Autel EVO Max series, including the EVO Max 4T manually in the native app and upload the MP4 or MOV video through Universal Upload at app.skyebrowse.com. ### How do I get accurate measurements from EVO Max 4T video? Turn on .ASS subtitle recording on the Autel aircraft before takeoff. Upload the .ASS file with the video and SkyeBrowse georeferences the model automatically. ### Does SkyeBrowse determine how a crash happened? No. SkyeBrowse documents and measures the scene. AI approach-path predictions are editable hypotheses for review, and AI Factual Diagram drafts neutral factual descriptions only. Neither establishes fault, speed, or cause. ### How accurate is a SkyeBrowse crash scene model? Public Safety & Enterprise models reach 0.1 inch accuracy and Commercial models reach 0.5 inch, without ground control points. Placing a known-size object in the scene gives you a check measurement. ## Related guides and resources - [Drone mapping guide](https://www.skyebrowse.com/news/posts/drone-mapping-guide) - [SkyeBrowse for accident reconstruction](https://www.skyebrowse.com/use-cases/public-safety#accident-reconstruction) - [SkyeBrowse Flight App supported drones](https://www.skyebrowse.com/supported-drones) - [Autel EVO II and Max 4T tutorial](https://www.skyebrowse.com/news/posts/tutorial-autel-evo-ii-and-max-4-t) - [Accident reconstruction checklist](https://www.skyebrowse.com/news/posts/accident-reconstruction-checklist) - [Forensic accident reconstruction with SkyeBrowse](https://www.skyebrowse.com/news/posts/forensic-accident-reconstruction-with-skyebrowse) - [How to 3D map a crash scene with a DJI Mavic 3 Enterprise](https://www.skyebrowse.com/guides/crash-reconstruction/dji-mavic-3-enterprise) - [How to 3D map a crash scene with a DJI Matrice 30T](https://www.skyebrowse.com/guides/crash-reconstruction/dji-matrice-30t) - [How to 3D map a crash scene with a DJI Matrice 350 RTK](https://www.skyebrowse.com/guides/crash-reconstruction/dji-matrice-350-rtk) - [How to 3D map a crash scene with an Autel EVO II V2](https://www.skyebrowse.com/guides/crash-reconstruction/autel-evo-ii-v2) - [How to 3D map a crash scene with a Skydio X10](https://www.skyebrowse.com/guides/crash-reconstruction/skydio-x10) - [How to 3D map a crash scene with a DJI Mavic 3 Pro](https://www.skyebrowse.com/guides/crash-reconstruction/dji-mavic-3-pro) - [How to 3D map a crime scene with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/crime-scene/autel-evo-max-4t) - [How to 3D map a fire scene with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/fire-scene/autel-evo-max-4t) - [How to 3D map a building for a fire pre-plan with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/fire-pre-planning/autel-evo-max-4t) - [How to 3D map a search and rescue area with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/search-and-rescue/autel-evo-max-4t) - [How to 3D map a building or block for tactical planning with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/tactical-planning/autel-evo-max-4t) - [How to 3D map a disaster area with an Autel EVO Max 4T](https://www.skyebrowse.com/guides/disaster-response/autel-evo-max-4t) ### Map your first site today Create a free account, upload one drone or phone video, and open a measurable 3D model in minutes.
