IMPORT into Pi 1049x576 > EXPORT( render) from Pi as 1052x576? Or even 720x480?

I have set up ALL the parameters, prefs and proj settings, I can tell to accept and finally render out to the same 1049x576

Results:

A] Uncompressed comes back into Vegas as 1052x576

B] DV Video Encoder comes back as 720x480

I have an issue with A], but why would B] which IS set up as PAL return into Vegas as a 720x480? Surely 480 is an NTSC height?

Anyways, I need assistance with this returning Pi Render.

TIA

Grazie

Some codecs only work at specific resolutions, and the DV codec is one of them. I'm not sure why you have an NTSC one and not a PAL one, but I think this has come up in the forum before -- try doing a forum search for DV PAL or something like that.

Whatever stage size you set in particleIllusion, that's your output resolution. So if your stage is 1049 x 576, that's what it is. If it's coming in to Vegas as a different size, then Vegas is reinterpreting the size based on a different pixel aspect ratio and you need to adjust that in Vegas.

I think.

"I'm not sure why you have an NTSC one and not a PAL one, " - I'll look . . but that might still not get a solution?

"Whatever stage size you set in particleIllusion, that's your output resolution." Sure, agreed .. but ..

"So if your stage is 1049 x 576, that's what it is." Well no, Alan, and while still within Pi it comes up with this different width? Do you want a screen grab?

"If it's coming in to Vegas as a different size, then Vegas is reinterpreting the size based on a different pixel aspect ratio and you need to adjust that in Vegas." I can READ this in Vegas as I said, but it is revealing the 1052 figure already in Pi. Now that can not be correct?

Grazie

Ah, if you're saving an AVI, some codecs require specific widths (multiple of 4 for instance). So 1049 may not be a valid width for the codec you're using.

If you're rendering PNG and still getting the size larger than the stage size, I have no idea.

Thank you Alan.

I am rendering to AVI. I have taken the width from the PREVIEW that VEGAS displays. If VEGAS is displaying 1049 then I would want to bring back as 1049. Doesn't that make sense?

If you are saying I need to make widths as multiples of 4 what would I need to do to make Pi "match" what Vegas displays?

TIA,

Grazie

Save in the exact same AVI format as the original movie maybe? Or save as a PNG image sequence (that will definitely work).

Alan? "Save in the exact same AVI format as the original movie maybe? " - Where? FROM Vegas or FROM Pi? And the 1049x576 or what?

Grazie
