Camtasia Studio 9. It is any loss in quality after recording, editing and then export the video using a lossless codec? instead of exporting to mp4?
trec is not an output option it's a file format. Your saved trec file is the original container; it's essentially an AVI with header data for mouse, etc. I just capture in AVI mode as I have no mouse concerns. Trivia: trec files do include an option to extract to AVI.
