Jerkiness in VS9

[yabadaba]

I'm getting 'jerky' video when I capture from my DV camcorder in VS9. Strangely, the beginning of a scene is often okay, but as it progresses the jerkiness starts to appear. When the next new scene starts the video will usually be smooth again, to begin with.

Are there any settings I should adjust to try and remove this problem? I have two other programs that produce smooth results so I suspect it's not a system problem. Latest patch applied.

My system specs are:

P4 3.0gb
2.0gb ram
40gb h/d space (one partition on a larger disc, not shared by o/s)

I have the same problem with VS9 but not with VS8. Can anyone can tell me why? dthomas212

Anyone?

Ok no-one is going to reply to your post because you have provided no real information. It's good you put the system specs in but also post:
Which type of capture and exactly how you are doing it. What type of file are you saving? AVI/MPEG? Using firewire/USB?
When you say jerky is that WHILE you capture or when you playback the captured footage.
If it is when you playback do you mean using VS or an external program?

Okay, I didn't know what other info would be needed as I'm still a relative newbie - thanks for the prompt.

Panasonic GS400 attached by firewire. Saving as .avi file. It's jerky whilst capturing, after capture during playback and also when played back in other applications (Media Player, for instance).

I've just downloaded a trial of Pinnacle Studio 9 Plus and that works fine, though I'd prefer to explore ways of correcting what is going wrong in VideoStudio 9 before I give in and purchase that!

Ok, I mainly answered your post to keep it bumped up the board as I could see you weren't getting a reply!
To be honest I know NOTHING about capturing, I use a DVD cam.
From the little I do know it could be that you are getting dropped frames during capture but why, I would not know.
Your system specs seem well up to the task. Do you have VS set to show dropped frames?
Hold on and I am sure someone far more knowledgable than I will post soon!

Thanks. Yes I did select the option to show dropped frames and there hasn't been any. Hopefully it's just a setting I need to adjust.

I am experiencing the jerkiness on playback with VS9 exactly as described in other posts.

I am using Video Studio Editor mode, capturing using “DV” format, which, on playback of the Project, seems to change to AVI. ( I am AVOIDING mpeg mode, because it will not transfer back to tape in my camera if I should so desire. )

The jerkiness is while I am PLAYING BACK the project.

This problem (or something similar) happened when I was using VS 7 some time ago, and tech support suggested that my disk was too full. I checked my disk, and I have more than 63 GB of available space.

I have been using system 9 for about a week, and this didn’t occur until yesterday. I have finished several projects for this movie... each under 10 minutes long, all seem to work well except work I have downloaded in the past 48 hrs.

I have installed the new patch.

I have tried downloading using Video Studio Movie-Wizard mode, and the problem exists on Playback there, too.

Hi Yabadaba,

What other background apps are running at the time? This can cause jerkiness in captures. Try shutting down, antivirus, sreensavers, anything that may be running in the background, and is not needed to capture and edit video.

You might try End it All to shut down unnecessary programs.

I have a GS400 and VS9 also. I capture via firewire and have not had any jerkiness. Its been a while since I did any capture so can't remember if I set the capture properties up manually or let VS9 and the camera work it out themselves.

I do always check the project properties before capture and from memory are lower field first, type 2 DV, Panasonic DV Codec, capture to .avi. I use PAL so the other details are the PAL standard.

I always shut as much as possible down when capturing, ie no internet, switch Norton off, switch Zone Alarm off, switch screen saver off, etc.

The last few captures I have had no dropped frames or any problems at all capturing up to 90 minutes of video at a time.

See my previous post on jerkiness. I tried suggestions found here (for which "thank you."). All were wise things to do. However, problem of jerkiness still persisted.

I then called ULEAD tech support, and the technician immediatlely suggested that I try Defragging the hard disk upon which I was storing my projects. I did so, and it worked! I noticed a slight bit of jerkiness on my first try, but subsequently it disappeared. I am now continuing additional downloading for the movie I'm working on. If the jerkiness returns, I'll be certain to return to the forum with my report.

Thanks for the help.

IMHO, Ulead should create a larger buffer (if there is a buffer at all) for capturing video. I have a laptop with a 5400RPM drive, and UVS will occasionally drop a frame during capture on this system.

But WinDV, an excellent freeware DV transfer utility, never drops a frame unless I do something disk-intensive while it captures. However, WinDV will occasionally buffer multiple frames (it shows the number of frames buffered and not yet written to disk, up to 99), which leads me to believe that if UVS simply did the same, many capture problems would disappear.

To anyone with a DV camcorder who is experiencing capture problems, all I can say is try WinDV.

I agree THoff, since reading a previous post of yours about WinDVD, I gave it a go, and it works great. Doesn't have the flexibilty during capture for splitting scenes and such. But the trade off for no dropped frames is worth it.
