In the Settings:motion detection: select Start recording on motion
In the Split recording time, set Maximum recording time and split if needed.
If maximum recording is not selected - the video recording will not stop
those settings apply to normal video recording and also to recoring video following motion detected

16. Better video quality?

You can try the following to make the video quality better:

• Settings:change the Resolutions, try also the beta resolutions. Beta resolution does not always works good but when it does it gives the best quality.
  
• Settings:Camera:check Camera2 API.
  
• Settings:Camera:try different Auto focus mode
  
• Setting:Advanced:check the stabilization mode
  
• Setting:Advanced:video codec : try H264 or H265
  
• Settings:Camera2 API:Video frame rate - 30 FPS
  
• Settings:Camera2 API:Video bitrate :
  
• Full HD (1920x1080): 10Mbps
  
• 4K (2840x2160): 48M~50Mbps
  

17. Run a corrupted video file with error icon on it

To avoid this problems - Please use the car mode that creates several files instead of a big one. But if you do have a corrpted file, try the following:
   

• Try to press the play button even though it shows an error message.
• Try to run it on Android using the VLC Player app.
• Try to copy it to the PC using a USB cable and run it using VLC PLayer.
• Copy the file to PC and try fixing it using VLC player like suggested in the following:
  
  
 
• Reconstructing video files using VLC Player
• Without any liabilty from our side, we did find this app useful. use the following method that explained in this tutorial 
  
   Use "copy/b v1+v2" to create a double video file and repair "half" of it which is actually full video.but use it on the following application:
  "Video repair tool" by Grau GMBH.:Video repair tool

18. How to get to 60 FPS:

• 1. stabilization off Settings:Advanced:Stabilization
• 2. Settings: Camera:Camera2 API: Checked
• 3. Settings: Camera:Preview on top: UN-Check
• 4. Settings:Camera2 API:Allow snapsshots: UN-Check
• 5. check different resolutions : in this case 4k beta resolution

19. Motion detection algorithm explained:

• Small animal 1 : looking for motion also in the 4 connectivity directions in the distance of 1 Pixels (up/down/right/left)
• Small animal 2 : looking for motion also in the 4 connectivity directions in the distance of 2 pixels (up/down/right/left) 
• Best option: Small animal 3 : looking for motion also in the 8 connectivity directions in the distance of 4 pixels but counts only if 5 out of 8 are different (up/down/right/left and diagonal) 
  
• Big Objects : looking for big connected objects

All motion detection are made after filtering the original image to grayscale and applying noise reduction filters.Comparing is done relative to reference image that is being modified in the rate of 8 pixels of the reference and 2 pixels for the new images.
Adaptive size algorithm should also be interesting. You can set the "Object connectivity" which means : how far to look for changes then the original suspected pixel (distance of x Pixels)and "How fast the adaptive background" which means how fast to get the reference image updated.

20. Video Quality optimization:

• Settings:Camera:Camera2API:checkSettings:Camera:Preview on top:Uncheck 
• Settings:Camera:Autofocus:continous video 
• Settings:Resolution:Beta try different ones
• Settings:Advanced:Stabilization mode:uncheck
• Settings:Advanced:Video Codec:try different ones
• Settings:Camera2API:Allow snapshots:disabledSettings:Camera2API:Video frame rate:30/60
• Settings:Camera2API:Video frame bit rate:high number 
• Settings:Camera2API:Extermen Night mode:uncheckSettings:Camera2API:Super Extermen Night mode:uncheck

20. After upgrading to Android 11:Are you missing old videos?

If you see no videos after upgrading to android 11, or if you record videos and do not see those videos, it is because the file system handling changed and the ".nomedia" file needs to be deleted.

You have 2 options of how to fix it:
• 1. You can manually delete the ".nomedia" file. it is a file that stops other galleries from viewing recorded files. it does not work on Android 11 since they change the way apps can handle files. you can still hide those files - but in a different folder "Downloads/KVRD" by selecting Settings:Special features:Hide from Gallery.
• 2. use my Android 11 Wizard from the left import button in the gallery or from Settings:About:Android 11:delete no media file & import files to android 11.

I am sorry for this - but android 11 have changed the way apps handles files and do not allow external folder access. I have spent allot of time creating those wizards to help you. Sorry for the inconvenient - this is android new privacy rules.

21. Disable the “Is Displaying Over Other Apps”

To quickly disable the notification, just toggle the slider to off. A note will display letting you know this notification won’t show up anymore. Again, this is only for the app that’s currently running—a new notification will show up if another app is displaying over other apps. This is a very granular setting.
