Do you think support will answer faster, than you type in google "gopro lrv"?

WOW aren't you just the smartest guy on the planet. Google who would have thought.
But as you can see by your own google search there is not really a clear answer to why, Also you google gopro, well sorry i have a gopro hero 3, never had any of the other ones, so i dont know if the 3 is competely different, again no real answer to what they are for.
SO yeah i emailed support, it is there camera you know. They might have a real reason for the files and why they are talking up space on my memory card, maybe it can be disabled??? I dont know the answer to that. DO YOU? I you have the answer PLEASE feel free to get back to me. thanks, Have a great day.

Drop an LRV file into VLC Media Player and it becomes pretty obvious what it is.
.THM extension is self explanatory as a thumbnail. Drop it on a web browser window and it'll show
you what it looks like. It's just a renamed jpeg file.

No, just an answer is all I was asking for and maybe proper grammar. Thanks

"Marooned, the LRV file is unrelated to the Protune mode. From my understanding of it the LRV file is a lower resolution version of the video recording used for preview purposes on the phone and tablet GoPro applications (less data to transfer wirelessly to the device running the application). It sucks that they take up space but SD cards are cheap and small."
This means nothing Unless the guy works for gopro, but as you can see, it’s his understanding not fact.

So how about this, until you can get give an actual answer and reply then please stop wasting thread space.

Trust me I’ve read all the stuff you can find on Google. Obviously the first place I went to..Duh only and idiot wouldn’t do that first.

Have a nice day.

His understanding happens to be correct. Question has been asked and answered.

Ok thanks for the answer, So why does the gopro do this. Just wondering. Seems kinda worthless, who plays stuff at low res now adays. All the cell phones and tablets out there are all pretty much HD or can atleast play it.

@Daemon
When i try to open them i just get a websearch can open file thing. So i guess i dont have that player your talking about.

Oh well just was trying to find out why this was happening and if it could be disabled, but from what ive read it cant.

VLC Media Player is a standalone video player that'll handle just about any type of media file.
If you changed the .LRV extension to .MP4 it would likely play in whatever you've got now
but name collides with original file, which is why they used LRV.

No smartphone will handle playing a full 1080p (or higher, or 60fps.. or 120fps) version of a
raw GoPro vid, and even if it could, there wouldn't be enough bandwidth over the low power
wifi connection, and even if there was the lag would be horrendous. The intent is to be able to
show a quick thumbnail and a playable version of the vid on any small screen, enough to identify it.
Basically, "Did I get the shot?"

Oh i gotcha now, I was thinking of like something you would upload to say youtube or something. So if you use the app, this is the file its playing back to you. Cause i just noticed the second file trm or whatever just started to show up after the last update. and the lrv on the update after i first got the cam.

Ok thanks all makes sense now, Just wanted to make sure it wasn't just my camera do this.

That would be a good solution for beam distance. The reason I chose the layout I did was because 1) I had the LEDs on hand and 2) they provide a greater spread of light and that yields a result I love as a film maker to light my scenes discretely.

I would love to see how you made that thing. looks pretty simple, Do you have a schematic for it?

I Have this one and is FREE.

Just got the Ridax 10 pin USB connectors in the mail (quick shipping to the US BTW). Anyways, I've made three perfectly working FPV cables with power-in.


Here's the Ridax blog that helps ID the pins: http://chargeconverter.com/blog/

It seems to me that plugging into the rear expansion port would be a good way to go for me. That way I could leave the case on the camera and just use the open back. Has anyone done that with this cable?

I have the Flytron one but don't want to cut my case apart. Plus I like the idea of powering the camera which the Flytron cable does not do.
