I have recently written a simple tool to record and replay my flight and would like to share it with the community.
And thanks IamSean for allowing me to include his video as a showcase of the tool's capability and the awesome graphic fidelity of MSFS.
Instructions
Extract and run FlightRecorder.Client.exe.
Features
- Record and replay with your aircraft or an AI aircraft in the sim
- Change replaying speed
- NOTE: when speeding up, your computer might not be able to load scenery fast enough and that will negatively affect frame rate.
- Save recording into a file to replay later or on another computer
- Export the recorded data into CSV for further analysis
- Quickly jump to any time in your recording (you have to Pause Replay first)
Notes: The tool records this list of variables from SimConnect Structs.cs for each sim frame. Some of them are only for analysis and display and don’t affect replay.
Incompatibiity
- FBW A32NX
- The 32NX starts to replace existing code that works with SimConnect with new code that ignores SimConnect. This means the aircraft will ignore the replay data Flight Recorder send to the sim. You will see that certain variables get replayed as in other aircraft, and the rest don't.
- Workaround (suggested by Abriael): since the recording still has correct data, you can replay it on stable/dev variant of the 32NX, or even the default A320.
- Default A320 and A23NX
- Aileron reacts wrongly to simvar `AILERON POSITION` when aircraft is in the air.
- I have reported this in ZenDesk #95574. I'll wait for Sim Update 4 before working on a workaround.
Other Limitations and Notes
- When starting a replay, your aircraft might be teleported to a far away location which doesn't have loaded terrain. This means the ground can jump up/down really quickly and you might get a crash (not CTD) due to damaged landing gear. Disable crash detection might be a good idea if you frequently replay your flight.
- I don’t know a reliable way to tell if an engine is running or not, so this tool does not auto-start the engine (because it doesn’t know when). Hence, you should start recording/replaying when engine is already running (or the aircraft will move without a running engine) and stop recording before turning off the engine (not really a problem, but the tool might not shut the engine down for you). Not doing that won't prevent you from replaying or using any features, but replay can look like your aircraft is powered by magic ;).
- Replay looks weird when turning on the ground. I’m not so sure what is happening there yet.
- To prevent fighting with MSFS own calculation, the tool sends freeze command when you start replay and unfreeze when you stop replay.
This means replaying might conflict with other tools leverating the same freeze feature (e.g. YourControl when you are not in control, other replay tools). - AI aircraft jitters back and forth during replay, especially at high speed. I'm still trying to figure out the reason.
Reporting Issue
If you have any issue with the tool, please report it in our GitHub page with information for troubleshooting such as screenshots, logs and profile exports.

Hello, ich cannot use the tool. I had to reinstall the OS and MSFS after changing the MB. Now its say "Cannot initialize SimConnect" to me. Skydolly and the Companion App having the same problem. Seems to me, that also other people have that problem, but i cannot find a solution. Can someone help me?

Download and install the SimConnect packages here: http://www.fspassengers.com/download/SimConnect.zip
nguyenquyhy 5 day(s) ago
Don't install that SimConnect though, that one is for FSX, not MSFS. Can you please ping me in Discord with the Discord link in description? I am testing a solution for this.

That one seems to work as well though. Just found this forum post (not tried it yet though)

exactly what i was looking for, thanks!

Merci pour ce soft qui fonctionne très bien
Le plus serait de pouvoir enregistrer tous les avions en multijoueur comme le faisait FsRcorder pour FSX. (team)
Bravo pour votre travail

You don't need to install SimConnect for MSFS. You can join our Discord server in the description above and ping me.

Hi nguyenquyhy,
1st of all AWESOME ADDON!
Really helps me as a content creator to make cinematic videos! 😀
Only one question if I may : is it normal that since last sim update when I use this addon to record my vidoes the sim just suddenly crashes / freezes?
Thanks!

Why do the taxi and runway turnoff light keep turning on and off automatically?
nguyenquyhy 11 day(s) ago
For some lights, the tool cannot directly set the state (on/off), so instead it will try to toggle the switch until the light state changes to what is recorded. Unfortunately on some aircraft, the light states sometimes stuck and the tool keeps trying to toggle the switch. I will try to improve this experience later.

This is a must-have app that is so close to being what FS Recorder was for FSX! One request - please add a KML export so we can upload track/altitude to Google Earth 😊

Working on it 😊

are there any shortcut keys that can be used to start & stop the recording for when flight recorder window is minimized?
nguyenquyhy 16 day(s) ago
It's not there yet. But I am adding that feature in.
LawnDartPilot 16 day(s) ago
Ok, would be great if you could add ability to bind keys for start recording, stop recording, play replay, pause, and another for rewind & fast forwarding.

Why can't the A32NX playback/replay never show up the animation for reverse thrust and spoilers?
Airbus_007 17 day(s) ago
yeah same for me
nguyenquyhy 16 day(s) ago
The tool sends the recorded throttle position to the aircraft. However, the 32NX disregard that data completely (due to custom throttle implementation), so reverser wouldn't work.

Has this project been killed off ?
nguyenquyhy 16 day(s) ago
No. Why do you think so? 😅

i have a recording but i cant open it becuase its a filtrec file and i dont have any apps that i can open with
nguyenquyhy 28 day(s) ago
The file is to be opened by Flight Recorder itself. Flight Recorder will replay your flight inside the sim. If you want to record into a video file, please use any screen record software (such as OBS) for the purpose.

where is the flight recorder client exe?

Hi,
You must run app from unzip folder inside, better with administrator.

Excellent prgram so simple and easy to use, better than some of the 'commercial' software for sale. Thanks for making this available.

Great little addon, thank you very much for putting the time in to make it, I'm sure it will get a lot of use.
A feature that would be great is the ability to record other aircraft as well (Multiplayer and AI). Hopefully this is something you might be able to add in the future

Hi ! do you know why Spoilers are not active during landing replay ? Thank you and by the way congrats for this awesome and friendly use tool ! A must to have !

I really hope this great program will be supported and developed further. It's much better and easier to use than what Asobo is currently trying. Their approach looks more like an advanced screen recorder. So, sitting in your own plane as passenger or just simply replay and watch your landings from outside is not possible.
This Flight Recorder on the other hand, is doing exactly what most users will expect (and also content creators). The only things I am still missing are the engine startup and the support of prop lever / rpm.
Please continue your great work!

Really good free alternative to other replay software and in my opinion better than the one Microsoft implemented with SU7. Only thing holding it back is the engine autostart!

5 stars for this mod - it's simply phenomenal. Could you help me solve one problem though? The spoilers on the A320 keep extended during the replay for some reason...any solution?
nguyenquyhy 2 month(s) ago
Interesting. I did not notice that before. Can you please try to check in the cockpit if the spoiler handle moves correctly? The tool records & replays the handle position so that should work.
iceaxe 2 month(s) ago
Thank you very much for replying! I'll check the spoiler lever motion from inside and let you know!
