Hi all.
I have one LRF file for each MP4 I record that’s of absolute no interest or use to me. Is there anyway to stop the AVATA 2 from recording these files.

All they are doing is eating up SD Card memory I need when out shooting. It's really annoying.

No, there's no way to turn them off, those are lower resolution video files used for previewing videos when importing.

I don't know what I did but my avata2 stopped saving lrf files after I went through and deleted all the video files on my sdcard. Could be a bug but I'll take it.

Thanks for the reply.
Enforcing them on end users seems like a terrible idea.

lol... That’s luck. Wish I could replicate that bug :-).

Just so you know, the Mavic 3 Pro has the same and there's no way to turn them off.  Hopefully you can turn them off with the Avata 2 and going forward but honestly, it's 2024 and this can't be a problem when the minimum microSD card anyone should be running is 128gb and 512gb cards are readily available at extreme low prices for those very few people left who still have an issue.

Didn't the Avata 2 just give you an unprecedented 46gb of internal space should you run out of room on your tiny microSD card; space taken up by those pesky low res files?  

Buying bigger SD Cards is always an option, but I’d much rather not have to deal with having to delete a bunch of files I’d never in a million years use every single time I backup a SD card.

I honestly wonder, what percentage of users would even use these files and why this is not an Option to toggle.

Those pesky files still use GB of space. Probably upwards of 6 GB if I were to fill the internal memory of the drone with MP4’s.  

Hi there. Thank you for reaching out. Regretfully, we cannot turn off the .LRF suffix files, however, you can delete it manually. Should you have other inquiries, feel free to contact us. We appreciate your understanding.

This lrf file business is why I'm selling the Action 4. I used to record my flight videos with this camera, and 11% of the space is wasted with these useless files... I ended up switching to an older Garmin VIRB, at least now I can record about 60 minutes longer... The fact that DJI is insisting on generating these files is beyond my comprehension...

Just hear this: YOU ARE WASTING MY VALUABLE MEMORY SPACE...!!!

I do not have them on Avata 2 now and am happy as this was one of worst DJI ideas

I dont have them either on my Avata 2.    How to turn them on though a they could be very useful.

Same here. Since i deleted them once, no new lrf files were saved on my sd card.
First i thought these was the motion data for each video file

What resolution are you shooting at? They can probably avoid saving them if you shoot in like 1080p since that's low res enough.

I don't see what everyone is so upset about. Every action camera and drone that has any form of wifi transfer feature does this and has been doing it for like a decade.

I feel it’s fairly obvious. Honestly.

They eat up GB of memory.

It’s unacceptable for DJI to even expect people to rename a file extension from a *.LRF to a *.MP4 for every single file they copy over via USB or direct from SD.

They are mandatory, even though I can’t imagine anyone ever uploading unedited raw low resolution files, while having to manually rename file extension files.

I don’t want, or won’t ever use them. Ever.

Where on the other hand, a simple ON/OFF menu button would solve this. I’m a programmer, so I know how simply this is to implement.

It would be nice if DJI would simply review this because honestly, making this mandatory makes absolutely no sense whatsoever.

You're not supposed to use them yourself, they're used by DJI Fly for previewing videos. Once you download and delete the main file, it will delete LRF (and SRT if recording that) too. With microSD cards being 4x or more cheaper than just 2 years ago, this is really some next level nitpicking.

4К/60 dlog

4К/60 dlog

Interesting, this made me think maybe it's connected to the codec...

I did a bit of testing with various resolutions and colour profiles as I thought maybe hevc doesn't need a lrf since it's more efficient(?), but the results I got are a bit inconsistent at best. Out of 7 short clips I recorded, only 1 had a lrf file and that was 4k60 4:3 d-log. 4k60 16:9 dlog, 4k60 16:9 normal, and lower resolutions didn't generate lrf. Could it be that simple, that only the highest available resolution at full sensor and 10bit colour needs lrf? I'll do some more testing.

ah, i see.  you don't really know what these are used for, eh?

some creators find them very useful for post video processing when it comes to optimized media or proxy files.

i agree there should be a switch to turn it on (default) or off.
not even sure what you mean about "renaming" files; that's so 90s.

Ah I see. Almost always, I will simply wait until I get home to look at the files on my Laptop. The rare cases where I need to see them on the move, it’s the laptop again.

Either way I never have any need for low quality files or any need to use the App.

Not nitpicking, it’s just a waste of space and an annoyance to have to delete these junk files every single time I backup my drone or SD cards.

No big deal. I just think it’s silly.

Hopefully DJI will add the option to turn them off in the future, or I'll be lucky enough to find the bug others found in this thread that pervents them from being written, either way, rather than just carrying on deleting these files every time, I’ll write my own little SD/Drone backup tool that automates backup and deletion of the files.

It's the little things that will make me happy :-)

I agree that the lrf preview may benefit for nle proxy process and live view.
But if it is not the case, dji should allow an option to turn them off.
Nowadays, sd card is very cheap so the space is not a concern. What more important is the lrf preview takes processing power, battery power, heat and video bitrate on the avata2.
It has been complainting since mavic 3 series and DJI tend to not fix it. so I guess these lrf preview is essential while in flight.
  
Solution :

1. if lrf preview is not necessary, turn them off completely in order to save some processing power for other useful function like real HDR video format (HLG) and RAW photo.


2. if lrf preview is essential for live view, please give us an option not to save in the sd card so it can free more bitrate for the main video file.


3. if lrf preview is essential and has to save in a file, please give us an option save those file either in the aircraft space or in the sd card. also file overwriting is essential if save in aircraft space.

I did some more testing, recorded 5-10 seconds of video with all resolution/frame rate/aspect ratio/colour profile combinations.

Looks like LRF is not saved when you shoot at either 4k60 (it is saved for 50 and 30 fps), or 100-120 fps in any resolution, regardless of aspect ratio or colour profile. Which is weird because those seem like the best use cases for LRF since those are the heaviest files, but live preview works perfectly fine for them in QuickTransfer.

I also noticed we lost 2.7k 4:3 at 100-120fps that we had on Avata 1
---

Edit: just tried removing all the LRF files from microSD card via usb, then powered Avata 2 back on and went into QuickTransfer - live preview still works for all of the files (I didn't have DJI Fly connected to goggles while recording so it's not cache from there or anything like it). So it does appear that LRF files might be useless in this case...

I like option #3 for sure.

Update..... I've noticed that if I switch to 4K / 60FPS, the AVATA 2 won't write LRF files. Writing at lower resolutions, the AVATA 2 starts writing LRF files again.

Guess you missed my last reply. It will not save those files at 4k60 and or resolution at 100-120fps no matter the aspect ratio or colour profile. 4k at 50fps or below or any other resolution at 60fps or below will save them.

Ah, sorry about that. Yes indeed, didn’t see that.
Thanks for this. Much appreciated.

You should speak for yourself ONLY... Those useless files (to me), are consuming about %15 of card space that other action cameras do not... I purchased Action 4 with great expectations, but I have other cameras that can record longer without filling up in the same or even higher resolution... DJI should make them optional... My process of recording flight videos does not require review or watching clips on the camera, so I see no reason why me or DJI need them (FOR MY PURPOSES)...

yeah that's right; that video is right out of 1997.  nobody does all that anymore.  
lol writing batch files on your windows computer still?

I also tried with Avata 2 and Mini 4P.
Avata cannot (?) create LRF files starting from 4K/60.
It creates them if using 4K/50

Mini can create LRF files 4K/60Mini 4P cannot create LRF for 4K/100  

Probably hardware cannot create/convert LRF files

And LRF files are needed for LightCut. If you don't have it, you cannot select file ower WiFi connection from LightCut - "Editing 4K videos not supported. Select another file."

If I connect SD card to phone (using USB dongle) then I can use and edit all files, LRF are needed, when you connect LightCut to drone using WiFi.

I would love to have these files at 4K60fbs ! Using them as proxy files in Premier pro!
