Picture Quality Problem : What am I doing wrong ???

Linda · Post by **Linda** » Wed Mar 30, 2005 1:48 pm

Hi,

I am using VideoStudio8. I imported some video from my JVC digital video camera. It was a very "blocky" display when I played it on the computer, but a friend assured me that it was like this when editing; but once finished and burned to disc it would be fine.

So I edited it, put in titles and music. Then I burned it to disc.
I played it back and it's still blocky with distorted music as well.

What am I doing wrong here ?

Which were your settings for importing (AVI, DV or MPEG) and burning afterwards your DVD, SVCD or VCD?

Also, some camcorders have both FireWire and USB connections, but can only transfer full-quality video using the FireWire connection. The USB connection is used when employing the camcorder as a webcam, and typically only delivers video at 320x200 -- this would certainly result in poor quality when creating a DVD.

Hmmm

Have to check this out and get back to you tomorrow

Not at all sure aout settings, as I've only just started using it.

Should the picture be perfect once I'm in editing mode, or was my friend right about it being blocky when you're editing ?

Your friend was correct when he/she stated that the Preview in UVS is not indicative of the final results you get when the DVD is created.

There are a number of reasons for this:

1. UVS doesn't know what settings you will use when creating the disk or video file.
2. The Preview window cannot be resized freely, or to match your desired output dimensions. Because the video is virtually always resized to fit the Preview window, artifacts and macroblocking result.
3. UVS tries to perform the Preview in realtime, and may need to take shortcuts or drop frames to do so.

But if by 'bloacky' you mean that there are a lot of block-like square pixels showing on screen and distorting the image, no you should not have that. As Torsten has just said, the preview screen is not great, but typically the view shown will be a bit more fuzzy than the final (i.e. not sharp but not 'blocky' either) and a little darker than the final product too.

Hello

I have excact the same problem. I use Moviefactory 3 and have a Panasonic NV-GS120 camera which uses DV tapes. I use firewire an have tried to create an DVD. I have recorded it in both PAL and NTSC and I have also recorded it in the best possible quality. But my picture is still blocky and in a very poor quality.

What am I doing wrong? I have used JPG - is BMP better?

Best Regards

Torben.riis,

In your respose you said you had a Panasonic nvgs150 camcorder. I am considering buying this model rather then nv it would be the pvgs150.

How long have you owned it? How do you like it? Does the 3ccd work as well as the advertisment says? How is the video quaility? My main concern is the picture quaility rather then the bells and whistles.

Thanks

Torben, your problem is different from Linda's -- she's talking about video, and it sounds like you are talking about still images.

Using FireWire instead of USB should fix her problem. Your problem I'm not sure about, since you said you used FireWire and JPEG -- that combination doesn't make sense on the Panasonic, it uses FireWire to transfer DV video, and USB to retrieve still pictures from the SD card.

My problem is the same as Linda´s. It is when I am capturing video I get the bad quality.

Rich2Putt

I am very satisfied with the camera. It works very well and the 3CCD seems to work.

I have owned it for 4 moths and there have been no problems at all. I don´t think that the problem I am having now is because of the camera.
Either it is me or Ulead Moviefactory which are causing the problem.

Linda,

Did you manage to solve the problem? I have the same problem too. My JVC bundle only comes with USB. No DV cable with firewire connector. The quality in my PC is so terrible compared to when I playback direct from camcoder to my TV.

Please help... :(

Which JVC camera do you have? Does it actually have a Firewire port on it (possibly called either 'DV in/out' or 'i-Link')? Just be aware that few if any video cameras actually come with a firewire cable to connect the port on the camera to the computer -- you have to buy that. But first tell us the model and we will try to work out whether it indeed does have a firewire port.

Another thought: do you have USB 2.0 on your computer?

Dear Ken,

The model is JVC GR-DX37 comes with both i-Link and USB port. But the package only give me USB cable.

Yes, I have USB2.0 port on my PC.

Just to check with you guys before trying to buy Firewire card and i-Link cable :)

USB is not a good choice to connect a camcorders to your PC. Most (but not all) camcorders only support USB 1.1 speeds, which doesn't provide enough bandwidth for full-quality (720x480 / 720x576) video. As a result, USB connections typically limit the camcorder to webcam (320x200 or 640x480) resolutions.

Maybe more problematic is that DV captures expect to use the Microsoft or Texas Instruments drivers for IEEE 1394/FireWire/iLink connections, so a camcorder that is connected using a FireWire cable won't even be recognized. You then wind up having to use a proprietary capture driver or utility to get your video off the camcorder.

Get a FireWire cable -- you'll be much happier.

I endorse what Torsten had to say -- except maybe the statement "so a camcorder that is connected using a FireWire cable won't even be recognized", when I am sure his finger slipped and he meant to say 'USB cable'!!

A Firewire card is essential if you are into video editing. They are not particularly expensive -- probably around $30 - $40. Some capture cards come with them on it (my DV2000 TV/capture card, for instance, has one on it plus an extra 'card' with a double Firewire and single i-link port on it). And some motherboards come with them too (like my Gigabyte 865 PE GT). But I assume you have checked and found that you currently don't have a Firewire port anywhere on your computer.

You will probably also need to buy a firewire cable unless you are lucky and one comes with the card. But in any case it should only cost you $10 or $15 (they are around A$15 here in Australia). But make sure that you buy one with the small 4-pin i-Link plug at one end (goes into the camera) and the bigger 6-pin standard Firewire plug at the other end (for your computer).

This little bit of extra expense, though, is well worth the effort, believe me.
