Hey
It is taking 2-3 hours to render my mpegs to dvd (say 2 hours long). This can't be right can it? A simple 45 minute vcd is taking about 45 mins.

Anyone able to help me.
I have amd xp 2400 chip 1 Gb ram 16 speed dvd writer 9600 radeon.

Yup, sounds about right in my experience.

It does not sound right if you are starting out with a mpeg2 file that is dvd compliant. But we don't know 'cause you only say mpeg file.

Also if you are starting out with a compliant mpeg2 file you need to tell VS not to re-render it.

Thanks for the replies.
I record the mpeg to svcd standard MPEG2Codec 480x576 resolution.
Do you think I need to rerender it to burn to a cd?
How do I tell vse7 not to rerender it?
Sometimes I burn a number of svcd mpeg2 files to a dvd using half d1 quality. Again must I rerender. The long time taken is the rendering. Burning is done in a snip.
Any tipes on what formats I should record in to limit the render time?

Cheers

I do not understand whether you are using CD Discs or DVD Discs.
Are your Svcd files old movies that you are converting to Dvd?

When you burn a disc you need a file that is compliant to that format, Vcd, Svcd, Dvd, Wmv etc
The process of rendering is to do just that.

Rendering can be drastically reduced if your capture settings correspond to the final burn settings.

I have a Amd XP 2500 and 1Gb ram similar to your setup, rendering a Dv-Avi to Mpeg takes about 2.3 times the run time. Similar times for Svcd to Mpeg as each frame has to be rendered.

thanks for caring!!
I burn both cds and dvds.
Typically I record a tv program to hard disk with my winfast 2000 tv card. I usuall use svcd quality for this as the reception does not justify dvd quality.
I often will burn a 30 minute program in recorded in svcd to a cd. This process takes about 45 minutes with the rendering being about 95% of the time.
Other times I will gather a number 4 or 5 od svcd programs (MPEG2) and put them onto a dvd in half d1 (i don't bother with dvd quality because it gives so little time on the disk and the initial program qaulity is never that good anyway) On sunday I burned about 2.5 hours of mpeg2 (recorded as svcd) to a dvd in half d1 qulaity. I took about 4 hours.

Am I making the process harder than it needs to be. What I don't get is how dvd recorders can record real time if my superdooper computer takes so long!

Any advice gratefully received.

One word: ASIC (Application-specific integrated circuits). DVD Recorders contain dedicated encoding hardware that is very good at one specific task: encoding MPEG2 video. The CPU in your PC is a general-purpose processor that can do a variety of things, but none of them as well as a circuit that was designed from the ground up to do only one thing.

Hi Bugsyboy

You said:-
On sunday I burned about 2.5 hours of mpeg2 (recorded as svcd) to a dvd in half d1 qulaity. I took about 4 hours.When you said (recorded as Svcd) do you mean captured, or are the files already Svcd.
If the files are already Svcd using them to burn a Cd, and you need to use the same files for burning a Dvd then I think you are stuck with the long render times.

If you are going to render a file from Svcd to mpeg 2 D1 then render times will be at a maximum.
Each frame is a different size, and the bit rates are different.
Every frame will require a lot of converting.

You can help to reduce render times by keeping your captured files the same as your final burn file.

If you are going to burn using Half D1 then capture to Half D1

These settings were taken from the options / change mpeg settings / burner module.
If you capture to similar settings to these then I would think you will reduce render times.

MPEG files
24 Bits, 352 x 576, 25 fps
(DVD-PAL)
Video data rate: Variable (Max. 2400 kbps)
LPCM Audio, 48 KHz, Stereo

Just another thought!

Have you tried capturing to VCD at full quality.
Use the files to burn a CD / VCD
Use the files to Burn A Dvd.

There was an article a while ago relating transferring VCD to DVD, the suggestion was that you did not need to convert to Mpeg 2 to complete the disc, but could burn Mpeg 1 files to DVD.

Hope this helps

Unless you have a need to get high quality video on a CD that will play on some DVD palyers drop the SVCD and don't look back. Use DVD compliant mpeg2 or the VCD standard.

If you don't like the all out VCD idea cap in a low bitrate mpeg2, about 2000-3000, with the same resolution as VCD. Use that mpeg2 for your DVD's, they won't have to reencoded.This will also give you the added benefit of a higher quality DVD since the mpeg2 file was only encoded once. If the quality is not as good use you want bump the resolution you cap at up to half D1 and use a bitrate of about 3500-4500. You can experiment with the bitrates but anything higher than the ones I mentioned above and you get little or no gain for those size resolutions, just a larger file.

Reenecode those to the VCD standard for creating VCD's, that should speed up the process signifigantly since you won't have to reencode for DVD.

Yes you can use VCD standard files on DVD and still remain compliant, you only have to convert the audio from 44khz to 48khz. How or if VS will allow you to that I don't know.

thanks for the info,

Thought i'd seen it somewhere!
