Output to DV

[Guest]

Hi. I'm experiencing a problem sending my DV-AVI WMM edit back to my tape on
my Canon ZR850. I've also noticed the same thing while using AVID FREE.
Everything is absolutely great, except that I notice the outer left and right
sides of the movie become cropped on the DV tape. In other words, the picture
that I see on my tape is slightly less than what I see within WMM. In still
other words, I'm losing picture when I transfer back to my DV tape. Why is
this happening?

Please help.

Thanks.

You've not switched a setting to 16.9 or something like that have you?

I think I've tried everything. Again, I capture my video from my Canon to
WMM. Works fine. I edit the file and output back to my DV. Obviously there's
no loss of quality, it looks great. However, when I inspect a random frame
and compare my TV and LCD (on camera) the sides are slightly cropped when I
find the same frame on WMM. It's subtle, but I want perfection, I just don't
understand it.

Does anyone else notice this?

Sorry not with you.

When you view a film on tv you'll have a slight amount of the picture
missing due to tv overscan. On most tv's it's 10% all round, but it does
differ,

Camcorder screens show various amounts of the actual picture, but as far as
I've been able to tell it varies from make to make and model to model and
there is no set amount.

Movie Maker shows a preview of the movie. This preview is low resolution,
though it should show it all.

So, MM should show you the whole frame, your tv and camcorder won't.


What happens if you recapture a piece of movie that you sent back to tape?

Hi Graham, thanks for sticking with me on this. I think you're right on the
money...overscan.

Before I had read your response I found another resource, here is the link:

It's just what you said.

There is also a workaround (not a fix, read on) provided that was fun to try
but ultimately didn't work for me because while it zoomed out and made more
picture appear back on the DV output, it left a slightly poorer quality to
the video. The filter also made for poor quality transitions.

I originally thought that I was editing video at the price of losing picture
(around the edges) but as it turns out (as you inquired about below), the
edited movie back to the DV could be recaptured back to MM with the same
"wider" preivew, i.e. the DV edit was the same as the orignal DV.

So anyway, thanks again. Do you have any thoughts?

I still need a fix for Overscan. What a PIA, all I want is perfection.

There is no fix without losing quality as you have found. It is the way tv's
work. In the overscan area they send teletext/pprogramme info etc.

I was converting a DVD to a Divx avi file. The DVD was 720 x 480, while the avi
file was to be 320 x 240.

320 x 2 = 640
240 x 2 = 480
so it looks like 80 pixels will be lost somewhere around the borders as well as
345,600 - 76800 = 268,800 pixels lost altogether, or 77.78% of all of the pixels
will be lost, making for objectionable blurriness and overwhelming loss of
detail.

Where is the MiniDV version of YouTube anyway?

Camcorder mini-screens seem to crop out portions of the recorded picture, and it
is rare to find a CRT TV adjusted right from the factory that has appropriate
bordering settings. It's like taking film to Fotomat, something's gonna get
cropped.

My latest YouTube video was 9:59.83 seconds, well under their 10 minute limit;
yet I find at least the last 0.83 seconds missing when played back at YouTube.
