I have some video in .dv format. It comes from old VHS digitalized. The quality is not good, they are spots of 30 seconds and each one has around 300MB. I have a new iMac with the last operating system. I have a lot of them and I have done some test in a couple to see the options.
If I click to one of the .dv it opens with QuickTime. If I file > export 720. It is saved to .mov and it have around 10MB or less. (remember from 300MB the original .dv). The quality seems the same.
If I import the .dv to iMovie and share > file > 720 and quality medium it is saved to .mp4 and it is around 40MB.
The original .dv with 300MB seem too big, specially when they do not have a good quality. Is it good to save it to .mov or .mp4, do I loose anything?
I do not see any difference of quality between QuickTime.mov 10MB or iMovie .mp4 40MB Why that difference of MB? is it a good option to save it to QuickTime just because it has less MB?
