screen sizes

[surfer]

Is it possible to see in Videostudio X6 the screen size like it would be displayed on tv? In X6 for example edited a video and saved it in Divx (6)- 704 * 398 its 1.7.
In VIdeostudio it is displayed full screen no black borders but on the tv there are borders top and bottom. Some have borders left and ride. Normally my tv fits every video to full screen so no black borders are displayed only when the movie has a 2:35 format.

WHen i set the videoproperties for the project in X6 in non square pixels then 2 black borders are displayed in the preview screen but they are on that video left and right not tp and bottom.

I would like to know to avoid the black borders and display full screen on tv but if that is not possible with the formats of the video then displayed in Videostudio as it would on my widescreen tv.
I have learned that if i do a math on the video size like: 704 / 398 = 1.7 then i can see that the video is full screen on the tv but i am wrong apparently.....
When the outcom of the math is 1.3 or 1.4 then it is a 4:3 video so not displaying full screen i thought to learn...

Hi Surfer

First for Project Properties tick Non-Square Pixel Rendering, generally this would remain selected.
Then make sure 16:9 widescreen is selected via Settings.
All other project properties can be ignored.

Your Preview Screen will display widescreen 16:9. to view the actual working area change the background colour Preferences (F6)

Some Standard video types use Non square Pixel Rendering, so a 720 x 480 video can display as 16:9, clearly 720 x 480 ratios are not 16:9 the pixels are stretched horizontally.
Think of the pixels as being rectangular.
720 x 480 can also be used for 4:3 video, again 720 x 480 is not 4:3, again the pixels use Non Square Pixel Rendering. The pixels are “Not Square but Rectangular”
720 x 540 would be 4:3
That’s the mathematics.

Div X does NOT use Non Square Pixel Rendering, so rendering to 720 x 480 will give that shape, however 16:9 is required so black bars are added
Makes since so far?
If you use 1280 x 720 create a DiV X it should display as 16:9

1280 x 720 is indeed 16:9 ratio.
As is 1920 x 1080 for full HD.

There may be one issue in rendering Non Square Pixels, it may produce a panorama effect 16:9 still having black borders. That depends on your sourse video and what you are creating.

Deselect Non Square Pixel Rendering prior to saving.
Share Create Video File –AVI – Options button to select render properties
Deselect Non Square- now render the video.

A bit of trial and error to see which option creates the true 16:9 video

Clear as mud

What is the properties of your original video fles.

You can also change the aspect ratio of the preview screen in VideoStudio by pulling sideways or up and down to match your TV - you can then save that layout by going to "Settings >> Layout >> Save to" and saving that layout so that you can get back to it at any time.

That is a very strange frame size you are using - the standard for NTSC is 720 x 480 - maybe it is your odd frame size which is causing the problem - your TV is expecting 720 x 480 and is confused by your 704 x 398.

Thanks for the explanation but i don't understand much of it.

The problem is that i cannot see if the movie is playing full screen on my widescreen tv. As a mather a fact is that the movie looks good in Videostudio (full screen and goog quality) but isn't that great in quality en blackborders on my widescreen.

I was hoping that i could see that in Videostudio then i do not make the video output.

The source are several different sizes like 704 x 400 and 704 x 396.
How to tell quickly that the movie is 16:9? The fastest method i know is to divide the lenght and hight if the number is close to 1.9 it is 16:9 and if it is close to 1.3 it is 4:3?

[BrianCee]

the pixel ratio is no guide at all and gives no indication at all of the aspect ratio of the video - as I said previously the standard for an non-HD video in NTSC is 720 x 480 - than can be either 4:3 or 16:9 depending on whether the pixels are square or oblong. Similarly for me here in a PAL country then my standard size is 720 x 576 and that can be 4:3 or 16:9 so just calculating the pixel ratio does not tell you what the format is.

HD video is a little easier as everything tends to be widescreen (16:9)

If you are playing around with pixel ratios in the belief that you can control standard or widescreen on your TV I would expect some strange results like black borders here and there - why are you not using standards that your TV understands and can display correctly.

You are absolutly right. But i do believe changeing the pixel ratio of a movie especially when it is goiing down the quality is going worse then the original..

Hi Surfer

Sorry for the confusion, but aspect ratio and non Square Pixels can be hard to understand…
As you mention Original.
Just what are the properties of your original video file.?

and why are you choosing Div X, maybe a Bluray or AVCHD would be better, and certainly not create those borders.
I assume you are playing a data disc or from memory stick? and not burning a DVD.

As Brian says HD uses 16 : 9 widescreen, the dimensions being 1280 x 720 or 1920 x 1080 for full HD.

But knowing your original video properties will help us to recommend a template.

Screen size is 704 * 398 and some others to like this resolution.

Mostly i use xvid but this was crashiong the last few times so now i tried Divx.

Strange thing (there is a post elsewhere on this forum) i cannot make a output video when the source is mp4. Videostudio always comes with the message resolution is not conform...

[erdna]

What is the format of your original video (digitized analog?, DV?, Mpeg2). Where did it come from (camcorder? graphics pics?). When saving to Dvix, did you set (specify) the output to this 704x398 format? How did you verify the pixel size (MediaInfo?)

[surfer]

Mostly the formats are mp4 or xvid HD. I look in Videostudio with the right mousebutton and ten properties.

To see if the video is frame based etc. i look in mediainfo, then the output that i make must also be Frame based or UFF, LFF.

Hi Surfer

I have been away for a few days so have missed some of your posts.

When you Share Create Video File – Custom – AVI to render a Div X you press the Options button to access the “video save options”

First set the properties under the AVI tab for Div X
Then from the General tab set the frame size, any using a 16:9 ratio, 1280 x 720 or 1920 x 1080 would do
However your video frame size is 704 * 398 (nearly 16:9) so setting that should be ok.

From the Corel Video Studio tab, you may have to de-select Non Square Pixel Rendering, a bit of trial and error with that particular setting.

Now render the video, has that removed those borders.?
-------------------------------
Interlacing, as far as I know Div X will always use Frame Based
