Discrepancy Between Project Size And Iso File



My project created with myDvd for a Bluray disc shows the disc is full with a little over 2 mins left, however the iso file generated is only about half the size (12.5gig) , as is the burned disk. Does anyone know why?


Using Nxt 2 Pro, all movies created in VideoWave, mp4 files - High Quality etc.. The project has menus.

CPU HP Envy17 running fully updates Window7 pro.

Becasue you are thinking in Apples and Oranges :wacko:

File Size is absolutely meaningless in video work.

Time is what matters and a 25 GB BD-R holds about 3+ hours at HQ Quality when making a BD Movie.

If you want to burn your little MP4 file and make a Data BD-R or DVD disc, then ago ahead and see if your Player will Play it!

Some will some will some won't but ALL will play a BD Movie ;)

Various disc capacities:

Blu-ray 25 GB Capacity:

  • HQ— 3:29

  • SP— 4:00

  • LP— 4:43

  • EP— 6:24

Blu-ray 50 GB Capacity:

  • HQ— 6:59

  • SP— 8:02

  • LP— 9:27

  • EP— 12:50

Yes I do!


So I took your advice and started to create video files from VideoWave using Bluray Authoring HQ setting. Several projects worked beautifully however a couple of them hang at exactly the same frame even when I ran them a couple of times.


I then deleted the picture where one of them was hanging, process stopped at the next picture.


Any ideas?

Yes... do something to those pictures with PhotoSuite (Photo tab - Edit Photos) - First thing is copy those picture to a new folder!!! that will be your backup


Then load them in PhotoSuite and do the Flip then Save.


Flip them again and Save.


Now try them. I am hoping that the processing of re-saving them will clear up whatever is making the render grumpy ;)

So I finally got round to trying your idea about 're-saving' the pictures. That did not work. Then I simply removed the offending picture from the project and the problem simply went to the next picture!


Eventually it became ridiculous as the project would end up with no content:-)


Finally I decided to restart the project from scratch. Tried exporting for Bluray Authoring without any transitions or music and this time I mixed up the picture placements, well the pictures that worked before now became the offenders!


I wish Roxio would stop putting out new versions every year with additional features (most of which quite useless for casual users like me) rather than addressing performance, error trapping and handling etc. This has been a problem for years.


Perhaps it is time to move on!

No one else has these problems so it has to be the pictures... However

(Update: I just slapped together a 118 picture BD project and it rendered and played OK - so I am fairly confident it is not a bug in the program)

For fun let's do a repair:

First thing to do is to turn off your Anti Virus, Firewalls, Registry Cleaners, etc.

Now insert your Roxio Disc. (if download, run the EXE)

Be sure you accept the offer to Check for Updates (this is for Roxio, not Windows)

When you reach the screen where Repair is offered, choose that!

When the Repair completes, turn your AV & Firewall back on and reboot.

Try that - if you still have this issue, try something like the Windows sample pictures.They are under Public Pictures\Sample pictures. Start with a new project.


There are only 8 but load them and start doing a copy and paste. Copy the 8 and paste them - copy the 16 and past them - copy the 32 and... Do this until the number of pictures is equal to or exceeds the number in your project.


See what that does and let us know ;)

You may be right since just 2 projects out a total of 8 are giving this problem, others some smaller or larger with same mix of pictures and videos from the same camera are processing perfectly.


I will try the repair avenue soon.

Ok the repair idea did not fix he problem.

Re-saving with minor change did not work either.

pulling my hair out did not do the trick either....




Removing 17 out of 86 photos that were freezing during rendering worked, so not satisfied I did the following:


Used the slideshow creator, first just the offending pics. then added original, and 're-saved' ones, and using Bluray authoring option all rendered perfectly!


Then to make sure it was not a fluke I took the mpg and stuck it in the original project, sans the offenders, renders perfectly.


VideoWave !!!!


What do you think?

Added auto motion to the photos and both offending projects with original offending pictures included, rendered perfectly!


why did I not do this days ago- :(


Sometimes the easiest is not the most obvious.


Thanks for all your input.
