DVD -/+ VR discs

skier-hughes · Post by **skier-hughes** » Wed Oct 05, 2005 12:41 pm

Has anyone made any VR format discs?
Is it just Movie Factory which supports this format, or does anyone know if Workshop does?
What I'm looking at achieving is recording a promo video to a dvd, then this dvd will go off to the customer, who will use a stand alone dvd recorder to film a short live event, several cameras and a mixer.
This VR format disc will then go into a duplicator to burn several normal dvd video discs which will be most compatible and cheaper then using lots of RW discs.
Time scales are important, as the discs need to be ready within minutes, so we have ruled out recording the event and compiling the discs using a pc.

Am I looking at this the wrong way?
Is there a different method that would be simpler?

All and any ideas and advice gratefully received.

Graham

Hi, not really to sure about what it is you want to do. But I would like to talk about the VR format. I think this is Ulead terminology. I think that VR is the same as DVD-R format. So, DVD+R = DVD+VR and DVD-R = DVD-VR. I think they are one and the same, but Ulead calls DVD-R, DVD-VR. Personaly I think DVD-R is the preferred, I think most DVD players (Home intertainment DVD player) will play the DVD-R. But now days new DVD player will pay ether type.

Now the digital camera will sent DV protocol, (format) to the computer to be captured onto the harddrive using IEEE-1394, (firewire). You will take the DV fromat then edit it. Then burn it to the DVD in a compressed form MPEG2. Most DVD players will play the MPEG2 protocol. The MPEG2 will be burned onto the DVD disk say using a DVD-R, (DVD-VR) technique.

I know this does not answer your question but you said any help was welcomed. So good Luck.

VR is a different protocol for writing DVD data to disc. It is not a Ulead specific terminology. Do google search to get the pros cons and differences between that and -+R or RW

VR stands for "Video Recording".
2 formats exist: The -VR mode and the +VR mode.
The -VR mode allows one to perform on disk editing of the video material, add, delete, cut, split along with Playlists.
Usually performed on a hardware device such as a dvd recorder.

You would make a mpeg2 file in -VR mode so you can edit it right on the disk in a dvd recorder. Cut or shorten the video, split the video (divide).
You can also ADD video to the disk (in -VR mode of course).
You can also use MF4 or equal to edit the disk directly.
This eliminates having to completely rewrite the VOB files (there are none). The main -VR mpeg2 file has an extension of .VRO
On a full dvd the file is usually about 4.3 gigs.

On a dvd written in -VR mode one can edit the video material.
On a dvd written in +VR mode one can only edit the menu structure.
The +VR mode uses VOB file containers.

The -VR mode is written using dvd-rw or dvd-ram.
The +VR mode is written using dvd+rw's.

If I record a 2 hour TV show on a panasonic dvd recorder cutting the commercials out is much faster and easier than using a computer. No comparision.

Thanks for the information. I have to think about and research what you are saying. One can get lost with the terminology and reference points.

I almost view +/- VR as uncompressed video like the type that comes out of a digital Camcorder, DV, Digital Video, using firewire (IEEE-13940. I know one can edit and work with DV protocol, (format), with video editors. But MPEG2 is a compression protocol, (format), that is difficult to edit with most software. But I get the idea that +/- VR is not DVD +/- R format one uses to burn DVDs. +/- VR is a protocol that is placed on the DVD. Now you say you can compress the +/- VR protcol to a MPEG2. Here is where I get lost. I am a newbe at this any way. I will resurch and get back to you. I have done some reading at videoguys.com. i will have to find more site for details. Or god for bid buy a book.

Thanks

Graham,

If you want to mass produce DVD's then you need to use DLT.
Take a look at DVDWS2 (not the express version)

Hi,

>>But MPEG2 is a compression protocol, (format), that is difficult to edit >>with most software. But I get the idea that +/- VR is not DVD +/- R >>format one uses to burn DVDs.

Normally a dvd recorder that does NOT have a harddisk cannot combine mpeg2 files because they shouldn't be edited.

If one records a 2 hour show in SD (Standard Definition) format approx 4.2Mbs then that will be 1 mpeg2 file in the .VRO container.
Everytime you cut a commercial out then there are 2 mpeg2 files on the dvd. So, if you cut out 5 commercials then there will be 6 separate mpeg2 files on the dvd in the .VRO container file.
You can trim the beginning and the end and still keep one mpeg2 file intact.

If you have a panasonic dvd recorder with a harddisk you can dub from the harddisk to a dvd-r or a dvd-ram disk in various video_bit_rate formats.
When you dub using that method the video plays back in realtime and writes one mpeg2 file to the dvd. Yes, the video(s) are resampled in real-time. Never an audio sync problem.

The -VR format is a mpeg2 format written to 1 file.
Even if you record 10 separate videos with the -VR format the video's are in the .VRO container. Hence, renaming the .VRO to mpeg only works properly IF there's only ONE recording in the .VRO container.

The -VR format is designed to be used with rewriteable disks.

The disks are written in the UDF packet writing format. So, I can format a dvd-ram disk in my panasonic dvd recorder. Then put the same dvd-ram disk into the computer and using the Ulead Data-Add packet writing software that came with MF4 simply drag & drop files to it using windows explorer. I don't have to reformat it using data-add program.

You do need to have the USISrv.exe program running in resident memory to do this.

Nice

Thanks guys, very nice wording. There is a lot of clarity in what you are saying. It would have taken me weeks to figure out that procedure. I have ulead MF4 I got with the DVD burner/player I got from pioneer DVR-110D.
My first DVD burner, I want to copy some old home movies to DVD. Plus learn more about video editing. But I got lost on all the terminology and how it worked. I will copy this post, document the terms and look up some of the terms so I understand them better, like VOB, DVD-RAM, VRO. I get the general idea for now.

Now get this, I like my computer's new pioneer DVD burner/player, I like the Ulead software it came with it, from what I know about it so far, but the Ulead DVD Player 2.0 that came with the Pioneer DVD will not play the DVD movies I put in the Pioneer DVD. Reason, the Ulead DVD Player 2.0 does not suport Dolby Digital. Other software I have does like PowerDVD by Cyberlink, Window Media Player. What is the big deal about having it play Dolby Digital. It makes me wonder about Ulead products. I bought the Pioneer DVD because of the Ulead software.

Thanks

There is a post in the MF4 forum with that problem.

Good to see I'm getting some discusioon on VR recording, although I still don't have a solution to my problem.
I am waiting for movie factory to come, so will be able try this when it does.
I have bought nero 7, as this includes vr recording, but it's just the same as all the other nero's on my system it just crashes the pc

sjj1805,
I know I could use DLT for mass producing dvd's, and I have workshop 2. The problem I have is that I need to mass produce dvds which have a company trailer on, which the company can then carry on recording onto when they get the dvds from me, as they are recording live events for the participants to take home immediately.
If nero ever works, I get some time to play and MF does turn up then I'll have another go at it.

Keep the banter coming....

Thanks

Not sure the -VR format is what you would want to use.
It depends on the dvd recorder your preparing the disk for.
You need to know the make/model of the dvd recorder and all
the formats it will write.
