This is how I make .tts files with the TTS V1.3(method is somewhat cumbersome but it works):
Here the DK_Taulov RLV is used to show how the .tts file is created:
When installing the TTS 1.3 software a "catalyst folder + sub folders" are created in the main "windows" folder. Any RLV you want to create a .tts file for, must be in that folder when you make the .tts file. The files can be moved to other locations later if needed - I still use the file structure from the Fortius software so I move the files.
Create the "DK_Taulov" folder inside the "catalyst/video" folder.
Copy the DK_Taulov.avi file to the DK_Taulov folder.
Copy the DK_Taulov.rlv file into the "catalyst/video" folder.
Copy the DK_Taulov.pgmf file to the "catalyst/programs" folder
Now the folders are created and files copied to the correct folders - it's time to use the TT software.
Use the "Import" "Real Life Video Fortius -> TTS" menu
The TTS will now open the import path "Windows/catalyst/video" and and all video files that can be imported, will be visible in the window.
Select the files you want to import and click "Import TTS".
I need the tts file for the TTS3.6 so I choose "No" to copy the file and move it manually later
The RLV is now imported to the TTS and the .tts file is created. Next step is to export the .tts file so it can be used in the TTS3 version.
Use the "Export" menu and select the DK_Taulov file.
Use your browser and save the file to the desired location - rename as needed.
Now use the TTS3 to import the created file:
Use your browser and find the saved file and import. If you move the .avi file to another location the TTS will ask for the new location.
Have fun riding.
