VS9 - rendering takes forever...

TerryE · Post by **TerryE** » Thu Mar 09, 2006 7:19 pm

I am new to VS9 (and video editing in general), but to render a DVD in VS9 is taking me 5-6 hours. Is this normal?

I read the sticky at the top of the forum. It says (in part):
"Caution: Never try to Create a DVD with anything in the timeline. Do not use the SHARE/Create Disk/Add Project control option."

Is this still true in VS9? If so, that is my problem, if not I will have to dig deeper. I am using all of the defaults as I didn't know enough to change them.

Thanks in advance
Terry

TerryE.
It rather depends upon the source material and "Smart Render"
Firstly read this post where I have given an explanation of compression
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=12118

Now a brief word about Smart Render. If you have smart render enabled and are saving back to the same format as the original then the software only has to "render" any parts where changes have been made such as transitions, overlays, video/audio filters, where titles have been added etc.

Next, When creating the final MPEG file ready for DVD authoring, the smaller the bit rate, the more the compression algorithm takes to work and so the longer the render time. It can as you mentioned above take 4-5 hours.

In fact I did one last night that took about 6 hours even on my kept in peak performance system. I converted all the AVI training files from the ulead site so that I could place them onto a DVD.

That gives me something to watch on my TV while my computer is busy rendering the next lengthy project!

Sorry to be such a newbie, but what is SmartRender and how would I enable it?

Thanks

After completing your edits you should before attempting to make (author) a DVD render the file to a DVD compliant MPEG file.
Click the "Share" tab.
Create Video file
Select PAL DVD or if your in the USA etc NTSC DVD
The usual "save box" appears asking you to supply a filename and where you want it saved. You will see an options button. this brings up a dialog box where you should make sure that you have ticked Perform Smart Render.

There are occaisions you may wish to overide this. One such occaision suggested by various members is to overcome out of synch problems.
(Again, see my posting link above.)

When performing smart render the video will appear to speed up/slow down even stop altogether in the preview box. This is the smart render doing its job, you only see movement in the preview box where changed video is being rendered.

So then I just use SmartRender initially when I am creating the Video file, not when I am burning the DVD?

The process would be:

1 Capture
2 Edit
3 Share / create Video File (with SmartRender ON)
4 New Project
5 Share Tab
6 Burn DVD (smartRender OFF)

Is this correct?

Thanks

almost correct.
At item 6 keep smart render ON.

At item 3 it is also normally ON but if you experience out of synch problems many members suggest turning it Off at this stage.

Ok, final question (for now

)

How much can I expect to decrease my render times with this approach vs :

1 Capture
2 Edit
3 Share / create / burn DVD 9SmartRender ON)

Thanks

I seem to be getting a number of similar posts regarding this or a very similar problem and so will direct further replies from those threads here.

Firstly, I have copied the pre-defined MPEG settings contained in DVD Workshop 2
I would however use Dolby (AC3) in preference to the suggested audio settings below.

Next, to answer the above query.
last night I collected together the video tutorials on the Ulead Website
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=11540
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=11645
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=11654
and created a single DVD. This process took some 6 hours of rendering.
They were all AVI files and so had to be completely converted, no smart rendering available here.

If I had rendered them twice I wouldn't dare imagine how long it would take, perhaps 12 hours?

Now if these had been DVD compliant MPEG files they wouldnt have needed re-rendering at all, the DVD would have been created in something like 15 minutes - the time taken to create the menus and then the VOB files.

If I had made edits to any of those files (had they been MPEGs) then just those edited parts would have been re-rendered, depending upon how heavy my editing was It may have added anything from a few minutes to a hour to complete the process.
