Not Able To Create Dual Layer VIDEO_TS Files

[grassercj]

I would like to write the video to the VIDEO_TS folder instead of burning directly to the DVD. I had alway done that in the past using VS7 for single layer DVDs.

I recently upgraded to VS8 because I bought a NEC 3520 dual layer burner and wanted to experiment. I captured my video using Constant 6000 bps and it was roughly a 5.6GB mpeg2 file. I did install the Dual Layer patch which allowed me to select the 8GB disk size and the dual layer timeline. When I used the Share option it used a dual layer timeline, so everything looked good. However, when I tried to write the VIDEO_TS file, it quit after writing about 4.2 GB. I have plenty of disk space, so that is not the problem. The Video_TS folder only contained VOB files. Normally it will contain IFO and BUP files as well.

I don't know if the burn to disk works. I wanted to try this first because those disks are about $8 a piece.
Any suggestions are appreciated. Thanks.

What is the harddrive formatted as?
NTFS or FAT32?
It should be NTFS to write files larger than 4 gig.
FAT32 has a 4 gig limitation of file size.

There is a utility in XP to convert FAT32 to NTFS without losing
any data.

Hope this helps,

The drive is NTFS and the issue isn't that I can't create a file bigger than 4GB. My source MPG file is 5.2 GB. When I render it to the VIDEO_TS folder, it creates four 1GB vob files, plus a 200 MB vob file.

I would have expected it to create five 1GB files, plus one file roughly 200 MB, plus some other files such as .IFO and .BUP files.

Yes, that should be the case.

Sometimes a user may have the temporary files location set to a FAT32
drive which can cause the problem but that probably isn't your case.

I have some large Mpeg2 compliant files and will try to burn a
dvd folder to the harddrive and see if the same occurs.
Will post back the results.

Hi,
Just created a Dvd folder of 8.2 gigs with all the correct files.
Maybe there's something wrong with the source material or
are you adding background music to the menus?

Mine worked.

OK, I guess the good news is that VS8 doesn't have a bug in it and the bad news is that it is something wrong with my system.

Prior to buying the NEC 3520, I would always capture at a rate of about 5000 bps Constant or less so it would fit on a single "single layer" DVD. Now that I can (hopefully) record dual layer, I am capturing at 6000 bps Constant and 8000 bps Variable. Maybe that is the problem. Time to experiment, and thanks for the data point.

I tried some experimenting and the problem of not being able to render more than 4.2GB is indeed relate to one of my disk drives being formatted to FAT32. VS8 is smart enough to split files at the 4GB boundry when creating them. Typically I capture to a NTFS drive, then during the render, the CONVERT files are placed on the FAT32 drive, then the final VIDEO_TS files are written back to the NTFS drive. This was mainly done to streamline the I/O. It seems that VS8 creates three files in the CONVERT folder, ~convert000.mpg (4.2GB), ~convert001.mpg (2.8 GB) and ~convert000.upd (1 KB). When creating the final VOB files, it only uses the contents of ~convert000.mpg. VS8 clips things at that point.

If I capture to the FAT32 drive, then piece things together in the project, then put the CONVERT folder on the NTFS drive with the final VIDEO_TS contents on the FAT32, it seems to work.

Is this a bug?

Is there any files larger than 4 gigs?

You really should convert to NTFS

It's as easy as right clicking the drive and selecting format, changing the drop down to NTFS. Might takea while though once you do that, Note the article I linked to above does state the possibilty of data corruption. So be sure to backup any important documents you have before converting.

The reason that this particular partition is FAT 32 is because I have a multi-boot system and share this particular volume with Window 98, which I keep around for some legacy software that I occasionally use.

Hi,

In VideoStudio 8:
If you make the working folder point to a ntfs drive &
assign the temp folder to a ntfs drive that should eliminate
the problem. Everything on my system points to ntfs partitions
but like yours I still run some FAT32's.

Under Preferences (F6) "Last tab on right" clear the checkbox
that's pointing to your home temp directory & on the
next line assign a temp directory to a ntfs drive. Your home temp dir
is on a FAT32 drive.

Hope this helps,

Thanks. That is working fine. I can use FAT32 for inital capture and for my VOB files. The working directory is an NTFS filesystem and all is well. I still think this is a bug in VS8. But at least I have a workaround.
