VS 11 Shaky clips after capture

terry dennis · Post by **terry dennis** » Sat Dec 01, 2007 7:32 pm

I have completed a number of projects both in VS9 and now in VS11 successfully.
However , I recorded a 10 minute video of my grandson's 2nd birthday yesterday and captured it today.
When I play some of the clips , they are shaky particularly on sound.

The mini DV tape is fine in all respects.
I disconnected the internet during capture and also turned off my screensaver. I burned a clip to DVD to see what the effect was and got a picture that was OK but with shaky sound , if you can understand that !

I have spent some time looking through previous posts but cannot see anything similar.

I hope that someone can suggest a possible reason and course of action.

You will probably find that VS11 uses the Type 2 DV encoder by default, and some (many?) people find that for whatever reason, their computers can't deal with Type 2. So when you are in the Capture screen, clicking on the Settings cogwheel icon and change the encoder to Type 1.

(Type 2 captures the video and audio in separate channels in a single stream, while Type 1 captures everything together. One of the symptoms of inability to deal properly with Type 2 can be jerky audio, but in more extreme cases can also include jerky video as well...)

You might also want to download and use a small freeware program called WinDV at windv.mourek.cz which a number of us here use for DV capture. You will need to use its Configuration button to ensure Type 1 encoder capture too.

Thanks for that information , Ken.

Following your advice , I have tried both Type 1 and Type 2 DV encoder and there doesn't APPEAR to be any difference. I get a shaky video AND audio during capture which is much the same when I come to play the captured clips.

I have downloaded the Mourek freeware as you suggested but , being a bit green , I did not know what to do with it !
I have downloaded it to the desktop. Is that OK or should it be loaded elsewhere?
In addition , can you tell me the sequence of operations in using it ?

I have the software, havn't had a need to use it yet, so, my point, is, downloading... Create a folder just for downloads, and save future downloads to that folder, rather than saving them to the desktop. Just open "My Computer" and navigate to your hardrive, click it to open and create a folder there. If you can, always make a backup of this folder to a CD or DVD as needed.

There is no real 'sequence of operations' for WinDV. It is simplicity itself. Yes, you can leave it (not your captured files) on the desktop, or place it in its own folder in Program Files or wherever you like as long as you know where to access it. Select a folder where the captured files will go by clicking on the 'Capt. File' button and give the series of captures a name. The captured files will all have that prefix plus a number to identify them when captured. Click on the Config button to select the DV Encoder Type.

You might also want to think about the 'Max. AVI size (frames)'. You live in a PAL country where you will have 25 frames for every second of video captured, so that is 1500 frames per minute and 90000 frames for an hour. If you intend to capture a full DV tape, set that Max AVI size to over 90000.

Have your camera on in PLAY position as per any other capture program, and press the Capture button. When capture is completed, Open VS and use the Insert Media command to insert the captured files.

Thanks for that quick response. I will see if I can follow that tomorrow !

This jerky video and audio is a bit of a set-back as I haven't experienced it before in the 3 or 4 movies that I have done !

By the way , I note that your reply was timed at 3.48am ........ do you never sleep ?

It should have shown an hour later -- obviously not taking into account daylight saving time! But my little dogs usually wake me around 5:50 a.m. every morning without fail for their morning walk!!

As for WinDV, let us know how it goes. If that gives jittery video/audio, then there is something wrong with your hardware...

Success with the Mourek software after a few abortive attempts !

It told me that there were 1184 frames dropped in a series of clips of total duration 11.50 minutes.

Needless to say , when I came to load into VS and play the whole project there were shaky sections of both audio and video.

Both VS and Mourek were set at Type 1 encoder and I had disconnected the internet throughout the capture.

Thanks for the extremely knowledgeable help so far. Any further suggestions ?

All other things being equal, WinDV is famous for not dropping frames. So I am afraid that if it dropped that many, there is something (seriously?) wrong with your hardware. Where is your Firewire connection? On a separate card or on your motherboard or even a TV capture card? (I have had all three!!)

If on a separate card, I had trouble with wobbly capture and corrected it by -- strange as it sounds -- moving the card further up in the AGP slots to be as close to the processor as possible. A little wobble remained in the preview of the capture, but after the capture finished, the captured DV had no dropped frames and played back smoothly both during editing and, more importantly, in the final burned DVD.

And upgrading my graphics/video card to a (powerful for its time) NVidia 7600 GS with 512 MB of its own RAM, took away any residual wobble.

Otherwise, do you have any friends with firewire on their computers? That way you could test your camera to see if it works properly on another computer. If it does, then it would seem your own Firewire card is failing. But if it doesn't, then you computer's Firewire connection may be defective. In testing this, you might also want to use your friend's own firewire cable as well as your own, to see whether a defective cable might also be a factor.

Sorry for the delayed response !

I have noted all that you have said but have not yet had the time to converse with a friend of mine who I know VS. When I get to speak to him , I will see about trying the various options that you suggested and take it from there.

I have overcome my present problems with the final video of my grandson's first 2 years on earth ! I have omitted the clip which has the most missing frames and edited out the wobbly bit of the other clip that was affected.
I have another query , but it is a different topic so I shall play by the book , go back onto the forum , see if its covered and , if need be , create a new topic!

Thanks for your help so far.

Regards

Terry
