Can I use my video editing software to change edit the video files and add titles etc…?
To edit the video files, add titles, and apply the special effects etc, you can use Viosk video maker ( https://www.viosk.com/ ). This tool can be used by a newbie to video editing world as well as by a professional video editor.
This is possible since VD4 files are fully compatible with the MPEG standard. However there can be compatibility issues with RT Analysis and Video Playback Tool. For example, if the number of frames changes, the data file (.RUN) will not be synchronised with the VD4 file any longer. Similarly the Chapter file (.CHP) can be pointing to invalid frames with the same cause.
