On the verge of buying but widescreen problems - help!!

[starfire]

Hi,

I'm capturing via Firewire to DV.

I will find a short clip tonight and email to you.

Thanks for your help
Simon.

I had exactly the same widescreen problem with a Panasonic camera, cured by Trevor Andrews suggestion of unchecking the "non-squared pixel render".

However, I now have a new problem in that the finished DVD has colour drop-outs when played back on a DVD player although it is fine played on the PC through PowerDVD.

This problem was not apparent before I applied the non-squared pixel fix.

Any ideas?

Hi Dave

What are the video properties of the captures files from the Panasonic camera.

If they are low quality intended for Pc / internet use, then I would expect the Dvd quality to be poor.

Widescreen

The normal video 4:3 frame (if you can call it normal) is made up of pixels. These pixels are not square but slightly rectangular.

Widescreen 16:9 uses the same number of pixels, the difference being that the pixels are stretched further, a bigger rectangle. This fills a 16:9 frame.

So how does the video editor know what shape the pixels are?

Not all cameras are capable of 16:9 format, a frame may be applied to the 4:3 to view as 16:9. This shows as widescreen, you think you have widescreen when in fact it is a normal frame. 4:3
A complicated subject, and not easy to sort out.

But start with your original video file properties.

I was having a big problem editing a video shot in a pseudo 16:9 mode. (Panasonic camera, actually 4:3 with black bars to look like 16:9). Problem was the video was squashed vertically & wide. Solved by another post suggesting to uncheck the Perform non-square rendering.

However, now there is constant flickering between colour & black/white whilst watching the produced DVD on a stand alone player. This was not apparent before the non-square pixel fix.

Any idea's?

Hi

You could try applying the Non Square Pixel Rendering.
Then use the distort function to stretch the video frame.
This would keep he pixels rectangular instead of square, it may help.

But it¡¦s a pure guess.
If its successful, give feedback, cheers

Nobody as far as I am aware has come up with a definite solution to this 16:9 pseudo problem. Other than to distort the frame.

Some have a frame applied to make 4:3 look like 16:9
Others are shot as a Pseudo 16:9 and fools the software into displaying the frame incorrectly. (undo non square pixel rendering restores that)

Good Luck

Trevor
