Maybe at that speed lose in camera stitching
It cannot loose stitching because it never had it.
or DNG
Maybe, haven’t tried. DNG at 1s interval sounds a bit insane to me. What are you planning to do with DNGs at that quantity? I thought DNGs are edited individually, and whenever you decide to just convert them into jpeg in some automated mode then why don’t just capture jpegs in the first place if you don’t really edit them anyway?
There were no download links
I’m not sure if it’s right to publish a reverse engineered data. I’ll give you some hints. This program worked for me (installing cert is not required, the qoocam app does not use encryption anyway):
Then try to do things with the app (shooting, downloading) and you’ll see all the requests you need. The protocol is asynchronous, meaning you can send shooting requests while transferring data at the same time.
The downloading speed over WiFi is 11 MB/s, no matter if the camera is shooting or not. It is capped by the WiFi chip in the camera which highest rate is 150 Mbit.
USB is faster, but I couldn’t figure out how to use it on Windows or Linux in any mode other than mass storage. The ‘Android’ USB mode which allows controlling the camera simply has no drivers for PC.
PS. Their software (the firmware itself, Android app and PC software) is crap, really.
For example, after upgrading to firmware 72 or 75 the camera may stop recording videos after ~20 seconds. What is even more funny - the LED will be still blinking, and the screen will be still showing the recording red dot and the timer. The only thing that gives it away - the remaining capacity in NOT decreasing, see this video: https://youtu.be/j4Edzfoqo2g
I stopped the recording, connected it to my PC and indeed found only one file 22 seconds length, it just stopped writing abruptly. And it’s internal memory, not even a memory card!
The only workaround is to downgrade the firmware to V62.
Also, don’t try to stitch a video longer that 40 minutes in QoocamStudio, it may crash. If you have a video longer than that - split it into several 30-minute jobs and stitch the fragments one by one.
Also, you may need to fix the framerate after stitching, it may change it from 30.000000 before stitching to 30.008333 after stitching (restore 30 with ffmpeg or something to get the audio and video back in sync). The problem is confirmed in QoocamStudio-v1.5.1.5, they’re still working on that.
The only things I enjoy are the audio input and the API that I can use to write my own software, otherwise I would have already returned it and bought GoPro Max, which has about the same image quality (if you stop counting the pixels and look into how much details the picture actually has).
PS. Funny thing: the lenses give sharper image on the peripheral and somewhat blurry in the center. Anyone can confirm that or is it just me?
