Created DVD much much smaller than original MKV file

Post by reddwarf4ever » Sat Sep 28, 2019 5:29 pm

I am certain this has been asked before, but not sure if an answer has been given that allows a solution.

I Created a DVD which is much much smaller than original MKV file, which is 15GB....the resultant DVD ISO image was 3.5GB.....I set it to DVD9 with FULL quality.....any ideas ..? I can’t believe that 11.5GB of the MKV was padding and not movie material.

Would love to know what I can d to rectify this thanks

Hard to say, but simply knowing that DVD9 holds max 8.5Gb, your original file is in FullHD or better quality.

Hi

That’s what I thought....I set to FULL quality ( assume that’s better than broadcast.....Two pass....

Even tried don’t re-encode if compatible file used bit mad no difference then tried forcing it by setting target to 7GB made no difference....

Am I using the highest settings possible ?

How do I get the creation log that was asked for

In menu there is "open log file" and "open log folder".

Anyway; your original is at least FullHD (1920x1080) and you are converting to DVD (720x576PAL or 720x480NTSC) so your actual amount of pixels is being reduced to roughly a quarter of original.
That would mean a bit less than 4Gb in full DVD.
So your end result sounds ok.

Hello

Interesting point, I was making the ‘wrong’ Assumption that the DVD would be Full HD, which of course it isn’t. Don’t suppose the quality is affected if it’s single or dual layer ?

To get Full HD would I need Blu-ray ?

Thanks, it seems you have answered my question, thank you... 8)

Totally believe what you told me, but doesn’t it confuse matter when adverts appear ‘windershare’ being one of them, which state HD video t a DVD, one even claims 1080p to a dvd......confuses everyone

You got it! ;)

Some programs advertize "HD" when they really are DVD. Some are just bogus, some use the confusing descriptions of standards:
  • HDTV
    720p 1280×720 progressive scan: 923,600 pixels (~0.92 MP) per frame
    1080i 1920×1080 interlaced: 1,036,800 pixels (~1.04 MP) per field or 2,073,600 pixels (~2.07 MP) per frame
    1080p 1920×1080 progressive scan: not a broadcast standard for ATSC 1.0
    Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame
Out of real broadcast signals the best is 720p - because 1080i is interlaced, so it can be bad in some movies but good in some.
