Rendering & Stretching

charles-mcguyer wrote on 10/21/2011, 6:42 AM
Vegas Pro 11 - I've been rendering with "HDV 1080-60i" and selecting "Stretch Video to fill output frame size (do not letterbox)." But to me the render doesn't seem natural. It appears stretched. Not terrible, but still stretched. If I don't select "Stretch Video to fill output frame size (do not letterbox)" will I still have the black space on the sides with youtube? I definitely don't want any black. I want my video to fill the whole space. I want the best resolution possible. Any suggestions? Thanks.

What have yoou been rendering to?

If you're rendering HDV to 1080 or 720 you shouldn't need to check that box as the aspect ratio is the same. Of course the pixel aspect ratio of HDV is 1.333 compared to HD's 1.000 and you should have it that way in your media properties.

If you're rendering to any of the standard SD formats then their "16:9" isn't exactly the same as it is for HD and you can check that box to compensate.

I'm rendering to HDV 1080-60i and to a m2t file. From Main Concept MPEG-2. If I uncheck "Stretch Video to fill output frame size (do not letterbox)" I see a letterbox while it is rendering. Thanks for your reply.

You have four choices when the source aspect is slightly different than the output aspect.

1) You can stretch slightly.
2) You can crop slightly and fill the frame.
3) You can trim the output dimensions slightly to fit the source.
4) You can do nothing

MPEG2 SD widescreen is just slightly wider than 16:9, being actually 16.394:9 or about 19.4 pixels wider than 16:9. That's why you see the black bars about 10 pixels wide on each side when you don't stretch.

Stretching the image to fill the frame ... well ... stretches the image. That's why the image looks stretched.

Everybody, you keep mentioning SD. In my original post I said HD. I'm still getting black bars unless I stretch the rendering, no matter what I choose for rendering. No black bars before rendering during playback in Vegas Pro 11 . But rendering is a different story, black bars on the side. It must be the way I shot the clips with the Sony HDR-CX100. Thanks for your replies.

OK, the problem was my camera settings. I reset the camera, shot a small clip, rendered to m2t, HDV 1080-60i, uploaded to youtube and it is as it should be. Thanks for your replies.
