HD to DV PROBLEM at DVinfo.net

John Eriksson · October 6th, 2003, 01:31 PM

First I converted the HD to DV and then when I was going to export it to tape via firewire.. BUT it become anamorphic (vertical strech) And I dont want that!!

I want "the black borders" How can I get that without going in to Afer Effects, And does Aspect HD support that directly?

I'm not sure how to do it with your own tools. But in Premiere
you can right-click on the footage and choose maintain aspect
ratio. If you load it up in a 4:3 project it will add black bars
automatically. You can do the same thing in an NLE like Vegas.

Yes, but the camera stretches the picture out anyhow in the end.. so,, what should I do?

How do I make a direct "black borders" -copy out on to DV tape without using After Effects or any special trix in premiere,

I just want it to give the correct black borders on scrub directly?
Is this somehow possible? (with or wihout aspect HD)?? I don´t like the anamorpic idea, cause I have a 4:3 telly! What settings or changes will I have to do in premiere or on the camcorder to get this to work?

I don't own your camera so I don't know. I can imagine an HD
unit offering such a function within the camera itself.

He is how to do it under Premiere 6.x:

1) Right click on a clip on your timeline.
2) Select "Video Option" -> "Maintain Aspect Ratio"
3) Repeat 1-2 for all clips.
4) Then export the timeline as DV.

If you have a lot of clips, export the whole time line in some interim format (CFHD -- for CineForm's Aspect HD, or HUFFYUV or uncompressed if not using Aspect HD.) Re-import the new one clip, set the fixed aspect ratio, then export to DV.

John, first of all it is normal that the camera "streches" the image. 16:9 Dv is recorded (just as 3:4) at 720X480 so the image indeed looks streched. Some camera can output the signal in 16:9 in a 4:3 monitor but you need a 16:9 monitor to view 16:9 DV images since they will look streched in 3:4. The reason it is recorded as such is to gain the extra pixels from the 480 horizontal lines (a real 16:9 image in 720 would have a 360 pixel height, or 3/4th the actual recording height of DV), to gain the extra 4th the image will look streched in a 3:4 monitor but will be more defined.

Hope this helps.
