Exporting to web/pc
Hi all,
Been hunting around for a complete answer to this question for a while and have yet to find one.
When exporting a SD DV PAL video for web or PC playback I normally try to downsize to the usual ‘PC’ dimensions, such as 640×480 (square pixels).
This normally results in black bars on the top and bottom. To get rid of them I crop the source to width 704 pix, removing 8 pix from each side taking into consideration the over scan area.
Is this the right way of doing this or am I going about it in the wrong way?
Thanks in advance.

That’s the only way I know of. PAL’s native aspect ratio makes the pixels slightly wider, so once you conform, it adds that width.

Thanks Angelo,
That’s the first straight answer I’ve had about this topic.
I cannot find any PAL based guides for best practise in this area anywhere.
The reason I asked is that a while ago I was on a forum about something else and mentioned that I needed to crop the image to get rid of the bars.
Suddenly I had a load of replies stating that there was no need to crop and that I was doing something wrong. From then on it I was unable to find any further info about this.
Cheers again.

Well there is no need to crop, say if you’re embedding a quicktime player into a page, as it’ll recognize the pixel ratio, but anything flash based Id play it safe and crop because it’ll be converted to square pixel. NTSC has the same/similar issue as DV resolution actually needs to be slightly cropped for the change to digital broadcasting.
