Assetto Corsa is a racing simulator with real circuits recreated through laser scanning, and much of the fun is lapping the same track dozens of times while shaving down your time. That means the moments you want to show friends usually come one lap at a time: a best lap that found three tenths, a start where you passed two cars into the first corner, an overtake where you ran side by side and won it on the brakes, or a drift you held through a sequence of corners. This guide shows how to record your driving with DOR, trim just those moments, and send them as a dor.gg link. Assetto Corsa joined the DOR supported games list in an app update in October 2026.
Handling recordings where every lap looks alike
DOR records Assetto Corsa as a whole-session recording. From launch to exit, menus, car selection, practice, and races all continue as one video, and DOR does not detect best laps or overtakes to create clips automatically. In racing footage every lap looks almost the same, so if you scrub casually it is hard to tell which one was the record lap. When looking for a scene, landmarks that repeat at the same spot every time, like crossing the finish line, the pit exit, or the start lights, are more reliable than timestamps. The basics of matching start and end points precisely are covered in how to trim game clips.
Steps to trim and send one Assetto Corsa lap
- 1Install DOR and start driving as usualDOR is a free Windows app. When you launch Assetto Corsa, it detects the game automatically and starts recording. Recording continues through session and car changes until you close the game, so there is nothing to prepare before you drive.
- 2When you set a time, note which session it wasSwitching circuits and cars several times a day makes the session order in the recording confusing. When a best lap happens, note the circuit, the car, and which session of the day it was, and you can count car selection screens to jump straight there.
- 3Use the finish line to find the lapWhen you close the game, the recording is saved to the library as an mp4. Within the session you want, pausing each time you pass the main straight separates the laps one by one, and checking when the on-screen lap timing updates shows you which lap set the time.
- 4Trim a full lap or just the key cornersIn the library's trim tool, keep one full lap from line to line if it is for comparison, or just your best corner section at 15 to 30 seconds if it is a quick look on a phone. For an overtake, start from the straight where you close in so the build-up is visible.
- 5Use 16:9 as the default for driving footageCockpit and hood views depend on side visibility and corner entry angle, so 16:9 looks most natural. 1:1 works for a drift seen from an outside camera, while vertical 9:16 tends to cut off the corner approach and exit, so save it for short moments.
- 6Send the link to racing friends with your lap timeWhen trimming finishes, you get a dor.gg link. For friends who drive the same circuit, add a line with your lap time and car so they can compare. They play it right away in a browser with nothing to install.
What to trim in each session, and what to add
| Session | What to trim | Info to add |
|---|---|---|
| Practice best lap | One full lap, through the moment the time updates at the line | Circuit, car, lap time |
| Qualifying flying lap | From the last corner of the out lap to the line on the timed lap | Qualifying position and gap to your previous best |
| Race start | From just before the start lights to the exit of the first corner | Starting position and position after turn one |
| Mid-race overtake | From the straight where you close in to the corner exit after the pass | Which lap it was and the rival car |
| Drift challenge | From the first slide to the end of the corner sequence | How many corners you linked |
| Drag race | From standing still before launch to crossing the line | Car and time |
Before you send a lap video
- The clip starts at a clear point like the finish line or the start lights.
- For a record lap, it runs through the moment the lap timing updates.
- Menus, car selection, and time spent sitting in the pits have been cut.
- An overtake clip includes the straight where the rival car first appears.
- After a full day of sessions, your recording drive still has well over 20GB free.
- For online races, you considered whether other drivers' names can appear.
How DOR records Assetto Corsa
DOR is a free Windows desktop app. When you launch Assetto Corsa, it detects the game automatically and saves the whole session until you exit as a single mp4. There are no per-lap highlights or automatic clips, so set the start and end with the library's trim tool, choose 16:9, 9:16, or 1:1, and send it as a dor.gg link. Friends who get the link can watch right away in a browser, even on a phone, without the app. On PCs with an NVIDIA graphics card, NVENC hardware encoding is used by default, and if you are worried about frame rate while recording on a high refresh rate monitor, see how to record at 144Hz without losing frames. To string several laps from the same circuit into a comparison video, the browser-based DOR Studio, which needs no install, lets you merge videos and overlay lap times as text; tips on ordering are in how to merge multiple game clips. Long sessions fill your drive quickly, and recording stops automatically once free space drops below 20GB.
