authoring and burning simultaneously?

[Malte]

Hi all,

is there any authoring/burning tool which performs the mpeg2 to vob conversion in "realtime" during DVD burning? I have a fast athlon FX and the cpu isnt that busy during the burning process, so there should be enough power for authoring and burning in one step. Is there any software which supports this?

Thanks,
-Malte.

Not exactally what you are looking for but I have been able to rip and burn at the same time using DVDShrink and Nero.

Keep in mind that it's the disc I/O that will cause problems during burn, much more than processor load. Authoring is pretty I/O heavy...

you should NEVER do anything else when you're computer is burning.
one little hickup and the disc will be unusable.

I tried an app a couple years ago called DirectRecord which theoretically burned your DVD as you capture it. It ran simultaneously with the capture app. You had to capture in elemental streams instead of program streams. It never worked right for me ...kept erroring out. The company that made it no longer offers it, so maybe it was too much of a technical hurdle. It's shareware so I would be happy to e-mail it to you if you want to give it a try.

The only reliable way to do this that I've seen is standalone recorders, like Panasonic, Sony, etc.

interesting idea especially if someone has very little hard drive space left

the possible problems i can see are
[when writing a file to dvd say your going to get 2 hours worth of footage on the disk]
this means the dvdrw is in use for 8 times as long as if burning at 8x
not only will this dramatically reduce the life of the dvdrw but it will also pretty much render the computer unusable for 2 hours

i would expect many burners to have serious heat issues if in use for 2 hours flat and any tiny error in burning means the dvd disc is useless


also if this was reliable i would have expected nero or some other big firm to have cashed in as it would be a good selling point to your average computer user who doesnt know much about video conversion
"copy your old video tapes directly onto dvd in real time 3 clicks of the mouse and your old home movie will be converted into a dvd which is virtually indestructable"

I think burners are better than you think on handling a high duty factor. Many times I've burned for 6 hours or more with only a break to change the disc. They pretty much would have to be rated for continuous burning, I would think.

looking at posts on here with dvd writing failures and overclockers.co.uk forums it is apparent that lots of burners do have heat isues when burning
if i bought one and this was the case then it would be going straight back
but with a lot of the early burners[they must be better by now] people were suggesting sticking fans on them

burning straight to dvd while capping is obviously not a good idea as otherwise nero.....etc would have made a program

perhaps it is something to do with capping takes a lot of system resources as does the dvd writer and with them competing for ram and cpu power errors are far more likely

also it would theoretically reduce the life of a burner by a factor of 8[for 8x burners] good for the manufacturer as wed buy new ones but not so good for us

would expect a major software company to develop a program like this in the near future as pcs are becoming ever faster and components and operating systems are supposedly improving
so perhaps it will become mainstream in the near future
i doubt id use it as i like to process a file first clean it up/remove adverts etc

I'm not sure what you mean by this. Do you mean that because it's burning at 1x instead of 8x? If so that's not the case because the laser power will be lower with a slower spindle speed. The dye used in DVDs is only successfully written when enough energy is deposited in it. With a higher write speed the laser dwell time on a particular location is less so the laser must run at a higher power. In engineering we call this power amount "area under the curve".

i agree that the power will be lower when burning at 1x [capping directly to dvd] than burning the complete file at 8x

but the total energy used over a 2 hour period at 1x will be greater than the energy used burning at 8x for 15minutes
i would expect the drive to warm to a full load temperature[like hard drives cpu etc] and then pretty much stay at that temperature for the rest of the time is in use
id expect the dvdrw to reach this full load speed about 3minutes into the burnand i very much doubt that the 1x burn would keep the drive any cooler than the 8x burn

it is running at the full load for long periods of time that used to contribute a lot to burning problems with early dvd writers

as for affecting the life of the burner
components are given mean time until failure
and while using a drive at 1x for 2 hours may not reduce its life quite as much as using it at 8x for 2 hours
i fully expect 2 hours at 1x to reduce the life of the drive by far more than 15 minutes at 8x
before i meant it would divide the life of a drive by 8 although in reality it is probably closer to about 6 if all burns are at 1x rather than 8x

as i doubt many people would use a capture card directly to dvd all that often the entire argument of reducing /not reducing the life of a dvd writer is not that impotant


my main reasons for not capping directly from dvb/video to a dvd are
1 it is likely to cause more errors when writing while capping as the dvd writer and capture card will be competing for the systems ram and cpu
2 you cant edit the video remove adverts etc


the original poster seems to have disappeared not sure if he wants to know how to convert a Digital Video broadcast into a dvd or a svcd into a dvd

Not exactly real time, but Ulead DVD Movie Factory 3 Disc Creator has a Direct to Disc feature. I haven't tried it yet, but you set it up, and it's supposed to capture, author and burn in one sequential operation.
