DVDfab reports smaller file size than explorer?

is this correct? i need to know to fit on 2x CDs

[Complication]

Smaller file size of what? Details from the Help Us Help You sticky thread would be helpful.

oh come on......when i burn to CDs, i look at the file size of video being encoded by dvdfab, does it include the combined output filesize? audio + video or just video?

[Complication]

I wasn't aware that DVDFab burned CDs. You learn something every day.

[signals]

Normally it reports combined. Try changing the audio type or encoding bitrate and see if it changes (it does for the profiles I use). The sizes in DVDFab are estimates, but usually correct within 2-3% for one-pass. Check a file with MediaInfo, see what it reports. Moving your thread to DVD to Mobile, use the most targeted one in the future.

Ahh... sorry, now I get it. I was thinking he was looking at the source file(s) in explorer and then in DVDFab. He was talking about the estimated output size vs. the actual.

omfg lol, someone is with the program at last hahaha

It looks to be out by 100Mb......

1. does dvdfab calculate MByte, rather than Mbit?

2. does explorer calculate MByte , rather than Mbit?

3. does a CD hold 650 MB or Mb?

[signals]

Ollie, we are not mind readers. I had to guess what you were asking.

MB=megabytes, which DVDFab and windows both use depending on file size.

a CD is around 700 MB.

If the file is just a little too large to fit on a CD, you can slightly reduce the video or audio bitrate, or the frame rate or the frame size to make it fit. DVDFab will recalculate the output size as you make these changes so you can see the effect.

[ollie]

yeah but i need to be sure or else i have to reencode 2hr per 2-pass

[ollie]

im using teracopy pro as a transfer mechanism bypassing windows, but this too under-values the filesize?

Anyone know whats going on?

[jtrevill]

Ollie,

Are you just slightly off, or is it large amounts? If it is a slight amount, it could just come back to the old 1 kilobyte is actually equal to 1024 bytes, not 1000 bytes, so you slowly lose space over large amounts of data...


Just a thought.

[ollie]

yeah thats what i a thinking.....its about 100mb for ~2GB

ie. dvdfab says 1920mb but it ends up ~2.06 gb

so its aboout 5% error from dvdfab
