Looked everywhere and cannot figure out what "switch" it is to do the below and STORE the files without compression.

My IP security camera will sometimes capture 4k images and vids, especially if raining or snowing and it will take too long to archive them. Sooo, What would the correct syntax be to store them without compression?

Here is the batch file I use..
--paste--
rem taskkill /f /fi "Master eq NT AUTHORITY\SYSTEM" /im iSpyMonitor.exe
rem taskkill /f /fi "Master eq NT AUTHORITY\SYSTEM" /im iSpy.exe

rmdir /S /Q E:\Dropbox\Private\HouseCam\video\GarageCam\thumbs

7z.exe a -r E:\iSPY\"%DATE:~7,2%.%DATE:~4,2%.%DATE:~-4% 10AM-GarageCam-VIDEO-BACKUP".7z E:\Dropbox\Private\HouseCam\video\GarageCam\*.mp4

7z.exe a -r E:\iSPY\"%DATE:~7,2%.%DATE:~4,2%.%DATE:~-4% 10AM-GarageCam-IMAGES-BACKUP".7z E:\Dropbox\Private\HouseCam\video\GarageCam\*.jpg

del /F /S E:\Dropbox\Private\HouseCam\video\GarageCam\*.mp4
del /F /S E:\Dropbox\Private\HouseCam\video\GarageCam\*.jpg

@echo off
rem start "" "C:\Program Files\Ispy\Ispy.exe" /secondary /minimized
rem psexec \\192.168.1.25 -u Master -p B****D -c "C:\Program Files\Ispy\Ispy.exe"
exit

Thanks for the help anyway.
Found a page with examples.
https://www.dotnetperls.com/7-zip-examples

Here I will show a bunch of options, and also some examples.
Compression levels:

Switch -mx0: Don't compress at all.
This is called "copy mode."

Switch -mx1: Low compression.
This is called "fastest" mode.

Switch -mx3: Fast compression mode.
Will automatically set various parameters.

Switch -mx5: Same as above, but "normal."

Switch -mx7: This means "maximum" compression.

Switch -mx9: This means "ultra" compression.
You probably want to use this.

Did you use the letter O or zero? The m parameter should handle the compression with zero being no compression.

A zero.. Duh! :p
I skimmed a few 7zip pages and it said that (-m=0) is it..
Maybe it needs placed somewhere else in the command?
