I am using Ulead VideoStudio 8 and curious if others have the same result I do, I am editing a avi movie that is about a 1 .5 hours long and turning the avi file I have into a DVD that comes out at medium setting to about 4.3 gig burned and about 8.9 gig on the drive. I am also using a 3.2 Pent 4 with 1 gig of ram and notice it takes about almost 2 hours to complete the entire transition from beginning to end of burn. Seems very long time considering other programs have had much better speed , any suggestions for decreasing these speeds while keeping quality, cant get much faster when it comes to today’s computers at least?

Consider yourself lucky. I have done a 2 hour project on a P3 600 mhz with 256 mb of ram, and it took over 12hrs to do!

WOW!

Well i fthis is luck then I think I might need to look for alternatives cause I found others that are faster but always liked ulead and didnt want to switch. 12 hours, I wouldnt do that..

When you say,

" it takes about almost 2 hours to complete the entire transition from beginning to end of burn"

are you saying that from the beginning of rendering to end of burning a DVD you only have to wait 2 hours? Surely not!

Just what business gets done in that 2 hours?

That's a bout right, to do a straight conversion of a 1 hour DV-AVI to MPEG with a P4 3ghz takes about 1 hour. Transitions, filters overlays etc can add to this, especially if you have a lot of filters, then there is the creation of the menus and the time to burn. there is no exact time, even with two machines running the same CPU unles they are exactly identical.

There other apps that may yield you slightly better times but not by much.

There is also the question of your workflow. As you imply, and The Coalman assumed, as did I, you have a finished AVI file, which you then load into your burning module, and you then start to burn your DVD. In that burning process, the AVI is converted to DVD-compatible MPEG-2 format on the fly, which can be a bit resource (and time) intensive. While this can, of course, work, especially with a computer like yours, many people have had problems arise by doing this as they don't have enough computer resources to do it on the fly. The preferred - and safer - workflow is first to convert your AVI to the DVD-compatible MPEG-2 (Share > Create Video File). Apart from anything else, that will also allow you to play it first and make sure the final product looks okay before you burn it. That conversion process will take you at least 1.5 hours for a 1.5 hour AVI, and as the Coalman suggested, probably considerably more, even on a powerful computer like yours. I have a P4 3.0 GHz computer with 2 GB RAM, and I still allow about 1.5 times real time for conversion.

Once you are satisfied with your MPEG-2, you can then open the burning module and burn it (Share > Create Disc > DVD), making sure you click on the 'Do not convert compliant MPEGs' box which can be found under the little cogwheel icon in the bottom left of the burning module window (at least it's there in VS 8 - I don't have VS 9 yet). Depending on how fast you are burning it, this process might still take well over 20 minutes: I find I can fill a DVD, including the multiplexing, preparation of menus etc, in about 25 min - 30 min burning at 4x speed (the burn process itself appears to take about 14 min 53 seconds of that).

So all in all, the time you are taking is unavoidable, whether you do it as an initial render, then burn later, or whether you render and burn in one process. And if you can find a program that does all of this much faster, then please let us all know.

Two other noteworthy variables I forgot to mention..... if your using VBR the overall time will be slightly more, using two pass enconding will double the time.

Ok so it appears to be the same as others since it does take the longest to render about 1.5 hours as you say the final stages only takes few extra and the burn it quick also to the dvd.

One question, Why so slow? I see other stuff like TMPGEncDVDAuthor that rendors much much faster but since it will not do the avi right to the mpeg I have to use a outside source and thats where the sinc problem comes it. I use the ulead cause the sinc is always good But just so slow?

You answered your own question...... If you use only DVD compliant mpeg in a VS project with the same settings as the video it would take far less. Your comparing apples to oranges, your not factoring in the conversion time which BTW takes the longest out of everthing.

ok then why does video studio take 1.5 hours to render then same movie that VSO DivxToDVD takes only 30 minutes to do, formats are the same?

thecoalman · Post by **thecoalman** » Wed Apr 13, 2005 7:39 pm

As long as your comparing them converting the same clip to identical formats then I would have to agree that's significantly faster. I 'm just saying you have to compare the same thing. Even converting to different bitrates can affect the speed. I don't even have a full version of VS.....

Hi everyone

I was interested in Ken's comments about work flow as I was just about to drop a line asking if there's any noticable deterioration in quality if I made a video file first, then burned it to DVD later.

So far, if I make a video file but then want to put it on DVD separately, I still burn from the VSP file in case there are quality problems, rather than drop the mpeg into the create DVD box.

Am I just creating unnessary work for myself and is the quality from an earlier saved Mpeg 2 just the same as going through the render process from the top from a VSP (even if it is smart rendered)?

regards.
Gra

If you create a compliant mpeg file first, and then use that file in your Authoring project, as long as you use the "Do Not Convert compliant mpeg files" option, the video will be used "asis" -- meaning it won't re-encode your already encoded video
