If no trailing frames are enabled, it is possible to save the current frame of a .PCAP by using the keyboard shortcut <ctrl>+s when Ouster Studio is in focus.
Alternatively, display the PipeLine Browser by clicking on the “Views” menu and show the “Pipeline Browser” and “Properties” menu, select the “Frame” node, and press <ctrl>+s to save the data. Select “CSV File(*.csv)” in the filetype dropdown menu and an output path then press OK.
After this a new window pops up to change the precision and if “Write Time Steps” is selected, all frames will be written in CSV names. Be careful as writing all frames as a CSV takes about 3 times more disk space than the PCAP from which you are reading.
Hope this helps!
