All,
I read from my Sony DCR-TRV310 via IEEE1394 into VideoStudio 10+.
I set project properties as well as capture properties as follows:
MPEG2, 100% Quality, 720X480 4:3, Variable 8000, Dolby Digital 128Kbps, Lower frame first and 2 pass encoding. I make sure that all these settings are identical between capture, edit, and sharing.
Once the mpeg2 file is created during capture, then why should VS10+ try to re-render the file again for 3-4 hours if I just put a six second title on the beginning of the movie? My footage is roughly 33 mnutes long.
I thought smart rendering would work it's charm as long as I kept all settings the same.
I film two football games a week and try to get DVD's out to the coaches by the next day, if not the same day. I used to be able to do it with other software and the DVD were very acceptable. Am I missing something in the setup, or do I really have to set through 45 minutes of capture and then 3-4 hours of rendering again? I might add that I am a very new user of VS products, but have been doing this kind of work for 5 years.
I use a pentium 4 2.8 system with 1Gig ram and two 400Gig SATA seagate barracudas spinning at 7200rpm. They are in a raid 0 - striped configuration. The board is a Asus P4C800-E Deluxe with onboard IEEE.
The reason I stated "un-edited" in the title of this topic is because I tried not touching the video at all after capture, and still it wanted to re-render when I went to make the file via sharing. Is there a way to tell in the edit window if the file clip(s) are going to be re-rendered or not? I thought I read that there was some sort of red and green line indicator on a previous version.
If I just go straight to "Create Disk", then it doesn't appear to re-render.
Thanks in advance for your reply!

Why does VS10+ re-render my un-edited mpeg2 file?

Ross,
If VS is re-rendering your unedited mpeg2 DVD-compliant video, you have probably not properly set up every video property to match the video file properties as in SHARE/Create Video File/Custom/... and/or have not checked "Do Not Convert Compliant Videos" or have turned off Smart-Render.
Whoops - I just noticed that you set up 2-pass encoding. That would probably do it. Turn this off because it isn't going to make slightly edited video any better than the original encoding.
OTOH, I have run tests that show that if you place DVD compliant video in the Edit timeline, with NO edits whatsoever, and select SHARE/Create Disk, set up BURN perties exactly to match, 10+ will sit there and re-render the whole #@*^%$ thing.
When you say "go straight to DVD," you must mean that you SHARE/Create Disk/Select Video File - the captured, unedited video file. That would work as you describe, without rerendering.

John,
As far as re-rendering when creating a disk. I have always gone straight to the "Share" tab immediately after editing in a title, so I already had all of my oringial video and title sitting on the timeline. When I enter the "Create Disk" dialog, it has the original file selected. I have to delete it and "Add Video" in order to select the rendered file with the title on it.
This does not appear to render the file again for me, as I proceed. It only appears to deal with the menuing stuff.
Am I right in saying that there is no two pass encoding on Capture?
Is this why I would be better off bringing in AVI and then
doing my editing and using two pass encoding?
Lastly, what affect does the project Property compression settings have to do with the entire process. Does this affect only what you are seeing in the preview window, or does it affect capturing, editing and sharing. My concern is that I am trying to be sure that I have the same settings for sharing as I do for capturing so that I can take advantage of smart rendering. I just don't know how the project properties affects either.
Thanks again for your replies. This forum appears to be very helpful from everything that I have read on it.
Regards,
Ross

Ross,
I have never tried to enable 2-pass when capturing mpeg, but IMO, if it actually happened, it would immediately bring the computer to its knees.
For your light editing application that happens twice every week, capturing AVI(DV) would be counterproductive, as would 2-pass encoding. However, if you want to sharpen up quickly moving objects (like football players...), you might want to experiment with deinterlacing and if you have the time, 2-pass motion estimation.
Compression settings have always been a bit of a mystery.
1. When capturing direct to mpeg2, the transcode buffer fills more rapidly, when set to 100%, but I can't say I've seen any benefit to picture quality.
2. While editing and rendering video files, I leave it at 100%. Other users who have experimented have reported little or no difference.
3. IMO, it is not a property that causes problems if not preserved in all stages of video editing.

Hi Ross
When you capture your video select DVD as the capture format Not mpeg.
Use the options cogwheel to change the properties to:-
NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps
Lower Field First
(DVD-NTSC), 4:3
Video data rate: 6000 kbps Constant. you do not need variable. (up to 90 minutes)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)
After editing adding the titles
Share Create Video File-Same as First Clip
That will render and be relatively quick.
Have a look at my Quick Guide for Mpeg from the link below.

We have had many a discussion on the merits of dual pass encoding and VBR also. The way I understand this is: Dual pass encoding will give you a smaller file size and very good quality from a DV-AVI source, especially if you have some parts of your video with fast moving action while the majority is slow moving. Dual pass is going to run through the video once, evaluating where the bit rate should be higher and where it can be lower. In the second path it will then encode your video along those lines. If your video is pretty uniform in its motions, you will be quicker using a high enough CBR setting and only run over it once.
There is no point in using VBR or dual pass with an mpeg source. All that will do is force the program to encode again. After all, that's exactly what you told it to do, encode with a variable bit rate and use two passes to do it.
