I believe one of two things may be occurring (or both):When I start recording, I have such a spectacle on the microSD card
The first file from one to four seconds
data rate 75699kb / s
the bit rate 75877kb / s
Great ) image quality really knocks great quality !, but so what ...
Next file, the same recording, without stopping, start a new recording, etc. With cameras to record one point e.g. 50 seconds.
system on the same !, creates another file and its data;
Data rate: 31026kb / s
Total bitrate: 31153kb / s - and this is the whole record, and I'd like to have them in quality such as the file "test", which I presented above in terms of quality and quantity of data recorded per second and frankly, these short video clips that are impressive
Rather, it is not suggesting AutoExec? or the camera itself, as recorded in the files of lower quality.
I ask you, dear colleagues for help and answers as you solve me to have the best image quality and speed of data transmission bitrate )
My custom firmware 1.2.13 is, change them? and add some files to the card? After these first files that have the same record and same without knowing it and stop further part in different quality, wonder what creates such a good quality video recordings and then splits the file and the rest of the records in the inferior quality?
I greet and thank you for your help.
- I'm not sure which mode you're using, but I'd say VBR is doing its job. This means if you have a well lit room (or nice weather) and you're filming the same spot continuously, the bitrate might adjust itself if there are no changes to the scene. If there's no noise or visual changes to your subject, the camera is basically reusing pixels. Try moving your camera around for 50 seconds, and check the data rate then.
There are modes for CBR (Constant bitrate), ABR (Average bitrate) and VBR (Variable bitrate). Search the forum, I believe there's info on how to change it through script somewhere.
- Your SD card might not be coping well with the High speeds. Make sure you have a high quality SD card if you plan on writing with very high speeds. I haven't seen an address that sets 75Mbps before, so to me that also looks like a product of a varying bitrate.
