GoPro Protune

[Ian Newland]

In Protune mode the camera is using maximum resources that is why preview doesn't work on the iPhone/iPad in that mode, it can't process 2 streams at once.

If you do the numbers a class 4 card is too slow, class 6 should handle the write speed, but class 10 is what is recommended by GoPro. The burst feature on the GOpro definatly requires class10 and they are cheap these days no excuse to not use them.

Don't buy class 6 cards, mine stops after few minutes.
Interesting because it can write 55mbps. Tested.

Thanks for the info about needing Class 10 cards. . . it took me a bit by surprise because I can(through an adapter) record full HD from my Sony EX1 onto those Class 4 cards which is a 35 mb/s codec.

[Prech Marton]

Protune is VBR, max peak was around 44mbit by me.
But still, my card can do 55 :(

[Ian Newland]

No ProTune is CBR Prech. What program/player did you read the 44mbps on?

[Prech Marton]

Bitrate viewer.

Enjoying the thread and learning a lot. I think my earlier question may be answered in the link Junior Pascual to David Newman's blog: "The CineForm connection: 35Mb/s H.264 H264 is hard to decode, much harder than 15Mb/s. So transcoding to a faster editing format certainly helps"

That said I'd still love confirmation form anyone else about what I mentioned earlier, for me the raw 24p Protune clips do not playback smoothly in VLC Media Player though they played fine pre-update, ProTune, and 24p. Playback is pretty unwatchable for me now. Same is true with trying to drop the raw file in Sony Vegas, which again I had no issues with GoPro clips pre-update. I'm getting the same thing on my primary computer and my laptop.

Not looking for a solution necessarily as I can already use GoPro CineForm Studio to get a playable file though obviously would love to avoid the extra step. I just want to confirm if this is the norm for others trying to playback with VLC or edit the files straight out of the camera without transcoding or, if it's just me and I actually do have a local issue that I should try to resolve.

Is it stated somewhere that Go Pro Cameras and Bac Pacs are not recognised by the Device Window via USB3? If not it should be. It had me stuck for quite a time, and just on the off chance switched to USB2 (as another plug, not specifically as USB2) and found it worked. Then I found a mention of it on some website...

Thanks for posting; I’m glad to see that it references the ‘everyday shooter’ being in mind with making this available. I was beginning to feel like this was intended for the pros only. So, it’s to be expected that ‘everyday shooters’ aren’t likely going to be experienced with post correction, etc.

A question for Ian Newland or Abe Kislevitz...

I have a Garmin Asus A10 running Android 2.1 or 2.2 - not sure which. Will the Android App work with my phone?

Know one will really knows until the app is released and people try on their various hardware. We have users devising ways to wifi connect to a PC, tablet or smartphone on our forum without the GoPro App but that doesn't answer your question. See link below.

Just a quick update, no clue what has changed but just did a new little batch of test clips in 24p with Protune and all is right with the world. Played back fine in VLC and on the timeline. Happy me.

I've just updated the firmware, very easy no trouble but with Protunes enabled I can no longer get 720 at 25 or 50FPS, I'm in UK PAL land.
Is it the case that those are not available now (unless I turn Protunes off) or am I missing something?

[Prech Marton]

yes, it is not supported (yet)
