Any time I make a recording, be it demo, training etc it always saves the captured background as a bmp in the library.
I can manually export, edit, then reimport each of the files as jpgs, which looses no quality but reduces the size of the published file by about 50%, and the project file itself by about 80%.
Is there a way to change the default capture mode to save me this massive chore each time I record a project? or some other way around it?
Sorry. No. Captivate uses BMP or PNG because these are lossless compression formats. JPG is lossy compression. So you may not notice the degradation but it is there.
I have noticed this too, i.e. the captured background is BMP, and the capture images are PNG. For example, my command line terminal window backgrounds are 4070.57K versus about 32K to 65K when I convert them to PNG files. Our demonstration files can be enormous because of the BMP backgrounds. It would definitely be advantageous to have a recording setting for PNG versus BMP for the backgrounds in Captivate.
