I am new to movies and movie editing, and need a few pointers. My cameras take movies in AVI format (One is a sony point and shoot, the other a MiniDV camcorder) I also have old family videos that I am transferring to the computer using a Canopus device. I am very confused about loss and losslessness, when it happens and what I should be doing about it. Once the video has been uploaded to my computer, does it lose detail every time I view it? If the file is burned to a DVD - does that lose detail in the burning or when it is viewed? Does it lose detail during editing? During the end process when the movie is rendered into a certain format? (Am I even using the word "render" correctly?) How can I save my movies from losing details? Thanks a lot - I have tried to read about this but it isn't making sense to me in terms of movies.
