I am currently in the process of converting alot of home videos that where mostly filmed in HD 1920x1080p, with some being 720p in MPEG4 format. I've been using a variety of programs but nearly all of them seem to produce really large file sizes in the final ouputted file even when they've been compressed. I have also been using Nero Video converting some of MPEG4 files which have already been converted twice from their original MTS and MPEG4 files, but for some reason I can never be able to fill a complete 4GB disc even when the extra added file (which goes over the red line) is only about 500GB in size. For example I have just converted some files to a TS folder ready to burn to a DVD (which in Nero Video prior to converting, including the menus etc, was about 3GB), but when I tried to add an extra file to fill up the free space (probably about 1GB left), the extra file exceeded past 4GB to about 5GB, even though the file itself was 1.65GB, which is exceded 4GB but surely not to 5GB. So I just removed the extra video file and converted what I could add. When I checked the converted TS file, the outputted file size was only 1.76GB, which means I would've wasted alot of DVD space if I had burned the TS file to a DVD.
Anyone know why it does this?. And why should a compressed video be larger in file size than the original?. I could've trimmed the video down but I didn't want to lose any valuable footage, but I suppose the extra video I was trying to add was around 40mins long.
And also, does anyone know why an MP4 file I tried converting to DVD in MPEG2 format (TS folder) which was only 1.57GB exceeded to 5GB?. I know AVI files do this but I've never known MPEG4 files to do this. I guess it's to do with the codecs used. Is there anyway or converting these files to fit onto a disc without losing too much and resulting in too much compression?.
