Rendering issues

[Andy Prada]

Mmmm! an NTSC DV widescreen sequence should be rectangular pixels @ 720 x 480 not as you have it.

Indulge me!

Create a new DV NTSC sequence – File..New..DV NTSC Widescreen 48kz etc
Copy your made up sequence into it and render
Feed back to me

Thanks for intervening here John. Normally an oversized image will simply blow out on a timeline i.e. will need to be shrunk (or blown) using the size adjustment. The indication here is that the sequence is oversized rather than the image. I can’t re-create this. The offset is odd too as normally the oversize image will be central to the screen, rather than offset, would it not?

The reason I mention the PAL-NTSC discrepancy is that I’ve had direct experience of it. In non-renedered mode it looks ok but, when rendered, looks offset.

Hi guys,

I have the same problem as the OP, but my situation is a bit different.

Here are my sequence settings:

editing mode: desktop
timebase: 59.94 fps

frame size 1920×1080
aspect ratio square pixels (1.0)
fields: not fields (progressive scan)
display format: 60fps dropframe timecode

audio is 48k and displayed in audio samples

preview file format: MS AVI
codec DV (24 Advanced)

neither the maximum bit depth nor maximum render quality boxes are checked.

I originally had the preview file format as I-Frame, but it didn’t render when I pressed Enter. So I changed the Preview file and it renders, but the image is blown up to where it isn’t supposed to be.

PC Specs:
i7 920 (OC to 3.7)
3 GB OCZ DDR3
640 GB WD Black
GTX 260 OC

Thanks for any help

There is a mismatch of frame size properties between what you are editing with and then using for preview. DV is limited to SD frame dimensions and will render and display a “zoomed” look when used to preview in a HD timeline.

Swap the codec to something else other than DV. Keep in mind that preview is not export format or result. DV on export will not look like the preview while editing (unless you tick then use preview box in export settings window).

Thanks for your advice.

I changed the codec to one of the Microsoft ones and after it rendered it looked better. The quality was poor though and playing back was a bit choppy.

Which codec would you recommend?
