2 preview window Problems

[Rends]

just testing the VS10+ trial and compared to VS8 i have a stuttery preview window while recording from my PCTV card.
In VS8 i have here and there a stutter in the capture preview window but in VS10 it stutters every 2-3 secs.
Well the created videofile (mpeg2,720x576,8000kb ,vbr) is fine so far but perhaps there might be something i can do for a smoother preview?

Next Problem:
if i drop a mpeg2 file (created with VS10 or with my DVD-HDD recorder) into the timeline i get a message that quality preview is dissabled because of my project settings. What does this mean and could it be changed? (I¡¬ve set project settings same as first videoclip)
This message doesn¡¬t appear if i put a mjpeg videofile into the timeline.

thx

OK your system specs look fine. No lets consider the TV card you ar capturing from. You haven't told us what it is and what format you are capturing to.

I have a Hauppauge TV card and it only captures to MPEG2 but on the plus side it does have a hardware MPEG encoder.

The forum recommend that when capturing - if there is a purpose built of software for your hardware - in my case it is WinTV2000 - then use that software because it was tweaked to be used for that purpose.

Think of other capturing software - such as VideoStudio.MovieFactory and the like as a general purpose capture software who's performance will not be as good as the purpose built one.

Whatever you use for capture will place a video file onto your hard drive. If you can capture in DV (avi) then it is considered more easily editable than other video formats (MPEG2).

One you have your captured video file on your hard drive then you can open it with VideoStudio or one of the other range of Ulead products.

hi,
TV card is a pinnacle PCTV Stereo and i can capture either in mpeg2 or mjpeg.
I don¡¬t use the pinnacle software for capturing in mpeg2. I use VideoStudio8 wich creates a better quality video and audio stays always in sync.
There is no Problem with the captured mpeg2 file itself if i capture from VS10.
The recorded file is fine. (I Forget to mention that i record with PAL DVD template settings with 6000 to 8000 Kb/s depends on source)

Again i have no problem with capturing but with the Preview window.
today i noticed another problem. If i try to shorten a videoclip, grap it either at the beginning or the end the Preview window doesn¡¬t update.
I can move the bar slider but the Preview window doesn¡¬t change. That makes it impossible to edit anything.

Overall i have 3 Preview window Problems now:
1. Stuttery when recording
2. No Quality Preview with mpeg2 file in timeline(Project settings)
3. No Preview Window update when shorten a clip

All the problems doesn¡¬t happen in VS8.

just noticed that the preview window updates if i select the beginning or end of a clip in the slider just below the preview window.

wonder why it works there but not if i do the same thing in the timeline.

Wiered or?

could this have something todo with VideoStudio8 i also have installed on my PC?

Sad thing is that i was close to get Videostudio 10

Why is it that people think the Preview within VS should be a pristine viewing? It is not, and will not be such, unless you are using a PC that is super powerful, and would probably cost in the $10K + figures.

This keeps getting brought up over and over. Previewing your timeline in Project Mode, VS must put everything togther On-The-Fly. This is not an easy task for any editor. It is not a rendered version, it does not take the time correctly render each and every detail. It is just going to let you see such things as your title is placed correctly, fades in/fades out, your images are positioned where you want them, they enter and exit how you would like, the audio can be heard, and any effects can be viewed/heard, the transitions are the ones that you selected, and are working properly, etc..

If you want a more accurate depiction, select a preview range. Do this in Storyboard or Project Mode on the Timeline. Use the Trim-Handles to select a specific time range. Then if in your Preferences settings, you have your Preview Playback set to High-Quality instead of Instant, VS will render that part of your Project, and allow you to see something that is close to how the finished product will be. NOTE that if your Project Setting is DVD (either NTSC or PAL), VS disables the High-Quality Playback. If so just set your Project settings to either MPEG2 or AVI. Now go to Share>Project Playback>Preview Range. Now you can see a more accurate depiction of your project. Or in Project Mode, press Play...

vidoman,
i guess you havn¡¬t either read or understand my problems.

I¡¬m not talking about a project with several clips in the overlay, added effects and filters and than wanting a smooth preview.

My problems appear if i put a single mpeg2 file in the timeline and then press play while in preview mode, nothing else. There i have a very suttery playback.

I¡¬ve also a very stuttery preview when i record something with my PCTV card.

I don¡¬t have both problems with Videostudio8!

About my third problem i read a VS10 review mentioned exactly the same problem:
http://www.digitalproducer.com/articles ... p?id=45512
"It's not quite as easy if you try to do your editing in the Timeline View. Unfortunately, unlike many other editing packages, when you drag an edge of a clip as it sits on the timeline in this view, there's no "edge-drag" capability, that is, you can't see the video footage moving as you're reducing or adding to its length on the timeline. That's not a showstopper, though, because Storyboard View's editing is so efficient and responsive, you'll end up doing most of your fine tuning of the clips in that mode. Anyway, because I'm so accustomed to editing on a timeline, I found VideoStudio 10's Timeline View sorely lacking."

So i¡¬m not the only one or?

So i wonder why it works in VS8 but not in VS10 ?

Ok I'll rebut in the same fashion:

HDV playback

There are several variables that impact smooth playback, and it is impossible to figure out the problem with so little information. Certainly having several video editing software packages from different vendors installed on the same machine often causes conflicts.



I regularly edit HDV on various machines with and without Smart Proxy, and get acceptably responsive performance ¡V and certainly haven¡¦t had any crashes. A standard part of my product demos is to put three types of video clips on the timeline together: An HDV clip, an MPEG-2 clip, and a standard DV clip. Put dissolves between all three, and watch it play smoothly through. Works every time.

BTW, this is Tobie's response to Charlie White's Review that you posted. If it is possible to place a HDV, DV, and MPEG on the same timeline and get smooth playback, then it will do it. However in my opinion and findings, it does not occur regularly in everyday situations where people have numerous other programs installed that may interfere with this...

That¡¬s why i¡¬m here asking for help. I thought it could be a more common problem so anyone knows an answer.
Sure if it¡¬s my PC related noone can¡¬t help but still let the question open why i have a smoother Preview window using Videostudio 8.

About my third problem. I¡¬m not sure.
Isn¡¬t it possible for SV10 to update the Preview window while moving the edges of a videoclip in the timeline ?
Or does it works on your end?
