New to Blu Ray Burning. How do you burn a 42gb Blu Ray ISO on a 8.5 DL DVD

[zipsick]

Just learned how to download and burn DVD’s with Makemkv with the help of People here at VideoHelp. Back for more help again. Just started trying to download Blu Ray DVD’s and got a surprise at their very large file size. First Downloaded Blu Ray DVD’s was 42gb’s. Right away I knew I knew I was in trouble because my DL Discs only hold 8.5gb’s. I know there were ways to resize the files but then I would loose quality and I was hoping not to loose quality. I wonder what People do about burning Blu Ray DVD’s. What is best? Should I resize the ISO to a smaller size? If so how would I go about this? Details please? Is there a good free program? What size and type do I resize it to? There wouldn’t happen to be any special Blu Ray Discs with large Capacity Storage out there to buy would there maybe???? Wouldn’t that be easy?? Well any help with advice helping me learn how to burn Blu Tay DVD’s would be Greatly appreciated! I would really like to figure this out and be able to burn the Blu Ray DVD’s. I know how to download them with Makemkv. My burner supports burning Blu Rays. They are just too big for my discs. Yuck!!!!

There are no "Blu Ray DVD"s, they are either DVD or Blu Ray, similar but different technologies.
You state you have a Blu Ray burner so just burn to blank Blue Ray discs, they are usually 25Gb or 50Gb capacity. If you must shrink Blu Ray sizes to DVD size it is inevitable that you lose some quality, all those extra bits are there for a reason.

Probably you're confusing the terms DVD (that is a physical medium, the optical disc) and ISO (that is a digital container for the storage on a hard drive of the content of physical media.. preserving their structure).

DVDs and Blurays are two TOTALLY different types of optical discs/media.

Both DVDs and Blurays can be converted to ISO, but you can't put (burn) the ISO of a bluray on a DVD disc.

How bizarre comparison... quick math: 1920x1080x30x3/2=93,312,000 Bytes per second (746,496,000 bits per second) , so literally we need to reduce bitrate from 747Mb/s to 20..30Mb/s (i.e. 37..25 times) or in case of OP question to 3.8Mb/s to 5.7Mb/s (i.e. 196..131 times) - it is practically achievable. Secondly water (and most liquids (if not all)) are practically not compressible.

OP can recompress (reencode) source to reduce required bitrate over 5 times - additionally some components can be (probably) safely removed so overall compression can be reduced.

I posted it the older topic about this.
This topic did a good job of answering the difference of Bluray discs & DVD discs.
