I've got a 16:9 question

Post by bennetts »

Right in the middle of shooting video my brother-in-law decides to switch to 16:9 on the Sony Digital8 camera. This causes everyone in the video to look extra lean. Is there anyway that this video can be corrected so that it blends with the rest of the video which is in 4:3?

I am using VS8.

Thanks.

How are you getting the video into your PC? If you are using a DV connection, use the "Split By Scene" option to separate the individual camcorder recordings from the tape into separate video clips. UVS will recognize that the video clips were recorded using different aspect ratios.

UVS does not permit you to mix 4:3 and 16:9 aspects on one DVD, but it can convert all video clips that are part of the DVD so that they are consistent, i.e. if you create a 16:9 aspect ratio DVD, any 4:3 video you add to the project will automatically be letterboxed.

letterboxed?

Does vs really convert 16:9 back to 4:3 or vise versa? and how. and what did you mean by letterboxed.

Yes, it will convert 4:3 video to 16:9 and vice versa.

Letterboxing is the preservation of the original aspect ratio by adding black bars, either on the side, or at the top and bottom of the image. This keeps the image from being stretched.

Obviously material that was filmed in 4:3 won't suddenly show the extra part of the scene that a 16:9 video would have captured, but the letterboxing will allow you to play back different aspect ratio videos undistorted when they are combined into one DVD project.

thanks a lot thoff, that will help me quite a bit, as I filmed my holiday in both aspects and now there are scenes in each that I want to put into both dvds.

If you have video in both formats, I suggest you convert the 4:3 to 16:9 and not the other way around.

16:9 is more future-proof, and going from 4:3 to 16:9 will simply result in letterboxing, some of which can't be seen on most TVs anyway because of the overscan inherent in analog interlaced TV. If you go the other way around, some material at the sides will be lost to the same overscan area.

Is it possible to have one chapter in 4:3 and another 16:9 on the same dvd ?

Not using UVS. I think DVD Workshop permits this.

I have used VS9 to produce a DVD that integrates both 16:9 and 4:3 video and it looks quite good on either a widescreen or older TV. I used the following procedure:
1) I captured the 16:9 and 4:3 video sections separately to different capture files, manually adjusting the aspect ratio property to match. (I captured directly to Mpeg2 at 8Mbps.) If you don’t capture separately, some of the video will be displayed with improper aspect ratio - squeezed/stretched.
2) I placed these video files in the timeline, editing out the overlapped sections, and created a project video file at 4:3. The DVD was burned with this mixed aspect ratio together with other 4:3 video files.
3) The resulting video file (and DVD) displays the 16:9 sections letterboxed within the 4:3 frame with perfect aspect ratio.
4) I suspect (I haven’t tried this) that if I had created the project video file at 16:9, the 4:3 sections would have been displayed letterboxed within the 16x9 frame.

I think he was asking about having both 4:3 and 16:9 video on the same disk without letterboxing -- that is in fact something Videostudio can't do, but I believe DVD Workshop can.

Torsten,
Do you mean displaying the video with sections cut off (rather than letterboxed with black sections)? If so, this amounts to the same thing, and can usually be achieved by selecting the display mode at the TV set.

In any case, my mixed 16:9, 4:3 DVD plays with perfect aspect ratio either way.

I have a question on my own 16:9 problem.
Will it remove letterboxing and convert to true 16:9?
I have a file recorded from broadcast in 4:3 with black bars at the top and bottom. So it really is 16:9. It plays fine on a 4:3 display but on my portable DVD player (which has a widescreen) I get black bars on all 4 sides to display it correctly.

What I would like to do is remove the black bars in the 4:3 recording and restore it to true 16:9 with no letterboxing stored. Can VS9 do that?

If you read my previous post to this I kind of want to do the opposite except that I don't need to mix 4:3 and 16:9.
I have a 4:3 file that is letterboxed.
I want to remove the letterboxing in the file (crop the image) and change the file type to 16:9 so it will display correctly.
Can I do that with VS9? If so it would be worth the upgrade price!

The answer seems to be yes.

I just placed a 4:3 video clip in the timeline, then created a video file with 16:9 aspect ratio. This produced an image at the full height of the 16:9 frame with black bars on the right and left sides. I believe that this is what you have already.

Then I placed this video file in the timeline and added a Pan & Zoom filter. I zoomed to about 134%, which caused the image to fill the 16:9 frame from side to side and cut off (cropped) some of the image at the top and bottom. I then rerendered a video file at 16:9. When played back on PowerDVD, it fills the 16:9 frame from side to side and top to bottom and has perfect aspect ratio. The image is only slightly degraded (from the digital zoom).

Actually what I have has black bars at the top and bottom of a 4:3 frame.
The opposite. But it sounds like I can do what I want.
Its just that VS7SE has no cropping or pan and zoom filters that I can find.
I assume I need to upgrade to VS9 to get that?

BTW, thank you very much for the reply and for taking the time to test that out!
