My mother passed away two months ago. I had the funeral recorded so that I can make DVDs and send to relatives outside the country who were unable to attend. However, the footage is 1hr 30 min long and about 6GB large, in .mp4 format. I don't have any DVDs large enough to burn it to. Can anyone share some advice on either compressing the file or other ways I can burn the disc to a blank DVD? Thanks.
