The latest version is v1.11.2.70. Some of your questions are not problem but normal operating rules.
- Osmo still stops recording after 28 minutes or so
In order to protect the stability of the camera, the video will be limited within 30min.
Sorry about the wrong firmware number, I can confirm that the version I just installed is the latest (1.11.2.70), I've been double-checking in the Osmo "about" in the mobile app after update. So yes,I am reporting the following issues regarding this last firmware version.
1/ About the 4 GB clip, I understand that's an old requirements on SD cards in FAT32. What I do not understand is why it still happens when the card is formatted in ExFAT inside the Osmo. The camera has the internal ability to format SD cards in ExFAT, but doesn't have the ability to record file of more than 4,2 GB ? Can't it be fixed by a firmware update ?
And please don't pretend that it's a implemented behavior in order to prevent the corruption of a longer clip. In any case the Osmo won't record for more than 30 minutes, so the long clip corruption issue is taken care of, sadly...
Besides, that hypothesis is even worse : if you're a manufacturer who's so afraid that your camera will produce corrupted clip while recording that you have to artificially make it create a new one every 4 GB minutes, well, you just don't sell your product before fixing this issue !
About the gap between clips : I took the time to do a bit of "scientific" experiment, filming with the Osmo (in 1080p50, the usual setting I use) a computer screen playing in loop a 5 seconds sequence with a bars and tone of 1 frame every second. Then I retrieved the 3 MP4 files, put them in an editing software timeline, and proceeded to calculate the gap between clips.
I found a hole of 71 frames, so that's around 1,5 second (at 50 fps) missing between the clips.
I'd be happy to share the footage (it is absolutely crappy, out of focus and extremely uninteresting to watch and unpleasant to hear ;-)), but frankly instead of me uploading and you downloading the 8.8 GB of my almost-half-hour, anyone with an Osmo can try it : film a clock (or a watch, or a computer clock displaying the seconds, and more precise if available) for 30 minutes, then compare the last frame of the first clip, and the first frame of the second clip : Tempus Fugit !
If you really want my raw footage, just let me know of an FTP server where I can upload it, or another way to send 8.83 GB.
About the audio shifting issue : I haven't had it this time with this camera (and this new firmware version), so there's the hope that this firmware version solved it. I still have previous footage shot with another Osmo (and an older firmware version) where the assistant director claps in front of the Osmo, and the audio has a good 1 second delay.
So after upgrading all of my Osmos, I'll check it on the next shooting to see if this issue occurs again. |
