image strectched in wide screen mode with panasonic pv-gs65

[weiqingh]

hi there,

i am using video studio 9.0, trying to use vs9's wide screen mode to download the video from my panasonic pv-gs65, which has this cinema mode option to shot video.

however, the video is strectched (when played in videostudio or other players) and when the video is burned to dvd, it still has black bars on top and bottom. is this a problem with my camcorder or the way i used the software? (i believe pv-gs65's cinema mode is done with letter box. )

thanks in advance.

Hi
What are your project properties ( file / project properties)
What are the clip properties ( right click the clip in the timeline select properties)

How did you capture, via Firewire, composite, usb, svideo???????

thanks for the reply.

i am using firewire.

my project properties are:
NTSC drop frame (29.97 fps)
edit in MPEG files
24 Bits, 720 x 480, 29.97 fps
Lower Field First for digital capture
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 8000 kbps)
Audio data rate: 224 kbps

the files captured in the library have 24bits 720x480 16:9 in their attributes. the file is strected wide with black bars on top and bottom.

i am using the format "dv" in the "capture" step. the captured files are in avi format. if i switch to "mpeg" in the "capture" step, the captured mpeg file has 720x480 and 4x3 (non-strected, but not wide-screen), and the quality is really bad.

i have read the first post (or faq) on this forum. it seems to imply that i should capture in mpeg format. (i have a powerful pc.) however, the project properties editing seems to affect only the editing mode? am i missing something here?

thanks for any advice.

Your capture properties look fine.

Did you remember to set the 16x9 aspect ratio when you created the Mpeg2 project video file AND then when you burned the DVD?

Does VS show the right aspect ratio in preview mode?

If so, try unchecking "Use Non-Square pixels ..." when you create the video file.

Panasonic's Cinema mode may be causing problems here because AFAIK, it is not a true wide screen mode.

Hi

When viewing in Video Studio.

If you set the project properties to 16:9
The black bars across the top and bottom of the preview screen are normal.
It is after all wide-screen.
VS may be confusing here, with an empty timeline you see a full black screen, even in 16:9.
If you change the background colour File Preferences.
You should now see a colour, which is the frame size and the black lines.
In 4:3 aspect, the colour should fill the screen.

Add your 16:9 video to the timeline.
The frame should fill the coloured portion.
At this point are the images within the video distorted or in proportion?

You captured to Dv-Avi which is the best option as data is copied from your camera without re-coding.

After editing did you Share–Create a Video File?
And as John asked did you use 16:9 ratio.

A thumbnail of your final video will be in the library as a Mpeg2.

What are the properties of this clip?

thanks for the reply.

yes, i set my project properties to 16:9. the image during the capture and preview phase in vs is distorted/strected. it's not as distorted as if you strectch a 4:3 video to 16:9 though.

i also specified 16:9 during the share-create phase. but there is no change. the image burned to dvd is distorted the same way as the one i saw in vs.

the properties of the clips have 16:9.

Read this review

Widescreen/16:9 Mode (5.0)
The PV-GS65 offers a letterboxed 16:9 mode which places black bars on the top and bottom of the captured image as well as the LCD screen during preview and capture. To access this option, select the cinema effect from the camcorder’s advanced menu section. A true 16:9 image is not possible on the PV-GS65 as the camcorder’s CCD has a 16:9 aspect ratio; thus any widescreen image must be digitally altered after capture, hence the letterboxing. As you can see from the above resolution chart (look for the aspect ratio arrows on the chart's corners), the PV-GS65's Cinema mode doesn't offer an exact 16:9 ratio. Additionally, the camcorder's standard recording mode's 4:3 ratio is a bit off as well (see next chart). It should be noted that the PV-GS65's cinema effect never claims to attain a 16:9 aspect ratio; the manual states that Cinema allows the user to capture video "compatible with widescreen TVs." Interpret that as you will.
