I am trying to burn a dvd. The file size is 4.38G. When I upload into Architect, it shows file size of 7.5G. I do not understand how this is happening or why. Can anyone please help? Thanks in advance.
The answer is probably because your video is being recompressed (re-rendered) and the bitrate is higher than your source file. Try reducing the bitrate in Project Properties - Disc Properties. Also DVDA tends to over estimate the file size by, in my experience, around 10%.
