Hi @JimmyB
welcome to the Stereolabs community.

The ZED_SVO_Editor line command allows you to manipulate SVO files:

$ ZED_SVO_Editor
You must provide arguments to this tools, here the list of them : 


 -inf     Print SVO infos

 -cut     Cut a SVO and save the svo part between <s> and <e> to another svo.
          -s or -e parameters must be specified.
          If s is not specified, first frame will be taken.
          If e is not specified, last frame will be taken.

 -merge   Add/Merge two or more SVO files into a single one.
          SVO files must have the same resolution and same ZED Serial Number.

 -cpr     Convert a SVO into another SVO compression format
          -m parameter must be specified.

 -m       Compression format to use with the -cpr option. m can be 0, 1, 2, 3, 4 , 5 or 6 for respectively PNG (Lossless), ZSTD (Lossless), JPEG (Lossy),  H264 Lossy, H265 Lossy, H264 LossLess and H265 LossLess  based compressions.

 -repair  Repair a SVO file by recreating a new SVO <svofilename_repaired.svo> with a recovered index table.

Sample usage:
"ZED_SVO_Editor -inf svo1.svo"
"ZED_SVO_Editor -cut svo1.svo -s 100 -e 200 output.svo"
"ZED_SVO_Editor -merge svo1.svo svo2.svo output.svo"
"ZED_SVO_Editor -cpr input.svo -m 2 output.svo"
"ZED_SVO_Editor -repair input.svo"

if i want to find the correct frames in order to cut the svo, is there a way to get a mapping of frames relative to timestamps? do i have to search for each timestamp the relevant frame and go over the entire SVO?
