Non-standard IFO files ?

Post by steveguidry »

Here's the process :

- capture with set-top DVD-R recorder.
- edit with MF3 (all current patches).
- burn DVD for customer.

Here's the problem :

All is fine with short DVD's - - anything under 1 GB is OK. But if the video goes over goes over 1 GB, my recorder splits it into two or more VOB files, each slightly under 1 GB. (all recorders do this, right ?) The recorder has NO trouble at all with making the jump from part 1 to 2 to 3, etc. And - - when the I go to the import screen inside MF3, that series of VOB files are reported as one big VOB file. But upon import, they go to the timeline as serparate files.

The problem occurs when I try to join the VOB files on the timeline : about 1.5 seconds of the video and audio are lost. This occurs exactly at the joining point. I can not tell if the info is missing from the end of file 1, or the beginning of file 2, or a bit from each.

After several rounds with ULead tech support, their answer is that "my recorder must be recording the IFO files in a 'non-standard' way." The support agent says that Ulead is aware of the issue, and the techs have discussed it, but they can not - - or haven't yet - - found a solution.

When I asked the agent to supply me with a list of set-top recorders that would make "standard" IFO files, he was unable to supply one.

Has anyone else solved this problem yet ? I'm open to work-arounds as well as real fixes. I'd even buy a different recorder if that would fix the problem.

And tech support - - if you're monitoring this, please review this case and either post a solution or call me directly for more info. I want to be part of the solution.

Import Titles

Post by GeorgeW »

The problem is probably related to how MF3 imports from DVD. As you mentioned, it creates separate titles when going from one .vob to another.

DMF 4.0DC allows you to import one huge mpeg file (this is a reported feature of DMF4 -- I don't have that version to prove that it works).

There are other software packages that will also import one large mpeg file (instead of separate titles). Go to videohelp.com and check their tools section and their user forum...

Hmmm . . . Owen at Tech support says that I'm likely to continue to have this problem with MF4.

I'm not averse to spending money to upgrade. $65 is peanuts, really. But this is really the only issue I'd be trying to solve with an upgrade. I don't want to spend the money and then find that it doesn't get me anything.

Anyone have MF4 have anything to report ?

Hi,
What make model of desktop recorder are you using and also
what MODE are you recording in.

You need not look at the VOB files. That isn't what Ulead is technically
importing. The program is importing the chapters (usually).
It is also said by others that you can copy the vob's to your harddisk and
rename them to mpg. Then import them into MovieFactory.
I don't use that method.

The new MF4 will import the complete movie. MF4 disc creator complete
version comes with many programs. There are bugs in the program like all
new software. If you buy it you should use the "Custom" installation
and decide whether or not to load the extra resident programs.
Some may conflict with your existing software on the computer.

If I was you for now if you don't have "Nero" ultra edition try it out.
Nero doesn't run next to Roxio very well so be aware of a conflict between
those 2 programs.
But, Nero can import the complete Dvd. You can download the trial
software. Nero is a good investment. Many users create the dvd folders or
iso file using ulead products and then doing the actual burning of the dvd
using Nero.

Besides having a video editing program one usually needs a reliable
burning program. Nero is the choice of many users.

Hope this helps,

I'm using a cheap Emerson (Funai) recorder, model # EWR20V4. For this project, I'm using the standard 2-hour record mode. I've set auto-chapters to "off".

Help me understand these things, please :

1) The recorder, as well as any other DVD players I've tried the original disc in report this as one big chapter, so I'm at a loss for how Disc Creator could be interpreting it as having multiple chapters. Moreover - - since I could just join them, and get rid of those chapter marks - - it wouldn't really matter to me if it wasn't for the fact that a second or so is lost at the point where the clips are joined.

2) Those breaks occur at the points where the various VOB file breaks occur. I have to believe that this is involved somehow. Give me some light on this, please.

3) I've tried the "re-name to mpg" method, and ran into a couple of snags : first, win 98 wouldn't let me re-name them - - I get a file named part1.mpg.vob, which won't import. Second, when I force it to rename them by using a command line window, and cryptic DOS commands, the clips get truncated from their original lengths to only about 15 seconds long each.

4) I then tried the "re-name to mpg" method again under XP, and tried importing the clips into MF, and the probelm was worse, not better. That is, _more_ information was missing, not less.

I have a "lite" version of Nero that came with my drive. I like it a lot. Maybe I will spring for the Ultra.

But back to MF4 : Do you have it, and will it do the import as one big VOB instead of recognizing the segments ?

Thanks for your time, and when I do get a workable solution, I will post it here.

Hi,
That would be the correct way to do it by turning off auto-chaptering.
MF3 should import the complete mpeg2 file.
The VOB file is a container for mpeg2 files. You can have more than
one mpeg2 file in a vob container.
Your recorder records the videos as mpeg2 video files. The dvd spec.

Check this out, using MF3 create a dvd with no chapters. Make the
dvd from 1 continuous Mpeg2 file. If you attempt to import the dvd
created by MF3 you will get the same as your getting.
So who's creating bad IFO's? It's the way MF3 and other ulead products
import from a Dvd-r. I would say the reason for the sound problem
is MF3, not the recorder. If you had chapters MF3 would split the movie
into small video segments(blah). Without chapters, it's VOB's (blah again).

Ulead has attempted to correct their new release(s) of software.
MF4 imports the complete mpeg2 file.

Everytime you hit record & stop on the recorder a mpeg2 video file
is created on the dvd. Usually if you can PAUSE the recording then
continue it the result is still one mpeg2 file.

If your recorder can record in the -VR mode using a dvd-rw you can
record a continuous mpeg2 file on the recorder. Then create a
"Playlist" and using MF3 import the playlist.

There is also another workaround for this by using DVD Decryptor and
importing the dvd to the harddisk using a different mode. If you search
through the forum there will be posts on that.
After the file is on the harddisk then rename the file to .mpg
The program is free.

Hope this helps,

MD
