Title text misaligned

[dmz]

Greetings,
Whenever I add title text which appears to be perfectly centered in the editor, some of it disappears to the right after rendering. To fix this I have to guess how far to the left I enter the text in the editor so it doesnt disappear. Is there some option which would allow me to enter text and have it appear as I enter it? The text is over the background of a colour and I suspect it doesnt like the fact that I am outputting the result as 16:9 which I thought vs pro x2 can handle.

Cheers

David

First I have to say it's a problem I have never come across in any of the versions I have used - but I do output most of my work from Pro X2 in 16:9 so I can assure you it does work. Text in my titles appears exactly as I view it in the preview screen.

but the wording of your question puzzles me a litte - you say "I am outputting the result as 16:9 which " and that puts the thought in my head that your project is NOT 16:9 - but you are creating a final file in 16:9

If your project is 4:3 and you just output as 16:9 some distortion/mis-alignment must occur - can you confirm exactly what you are doing

In any case there is no magic "correct offset" button - because offset shouldn't occur in a title rendered to the same format as the project.

Hi David

A similar problem to the images being distorted in your other post.............

I think it is related to Non-Square Pixel Rendering.

Can you tell us what video file you are creating?
I assume you are rendering to a format used on the internet, may be Flash,

Try this:-
From File Project Properties-Edit --- Disable Non Square Pixel Rendering.
From Share Create Video File -?? Choose the Options and disable Non Square Pixel Rendering.

My input file is as follows:

PAL (25 fps)
Microsoft AVI files
24 bits, 720 x 576, 16:9, 25 fps
Lower Field First
DV Video Encoder -- type 1
DV Audio -- PAL, 48.000 kHz, 16 Bit, Stereo

and the output file I create is as follows:

MPEG files
24 bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 16:9
Video data rate: Variable (Max. 6000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 3/2(L,C,R,SL,SR)

The option to perform non-square pixel rendering is unchecked.
Using the above options my title text is not wysiwyg and my photos are stretched even when I say keep aspect ratio.
something I have missed?

Thanks

Given that your original video is already 16:9 and your output also 16:9, I would in fact check the non-square pixel rendering box...

[dmz]

Thanks Ken. I did check the non-square pixel rendering and the text was wysiwyg and the photos kept the aspect ratio ! Why would that check box cause it to do that? or not checking it cause it to throw out text and aspect ratios?

Thanks

Hi David

Standard video uses Non-Square Pixel Rendering, this option should be checked as it is by default.

Notice that your video is 16:9 ratio but the frame size is only 720 x 576.
Using a calculator you will see that this is not 16:9.
The pixels are not square but stretched to shape of 16:9.

When you disable Non Square the video reverts to a 720 x 576 size and looks distorted, everything being vertically elongated, the associated text would look out of position when rendered.

My comment on un-checking this option was related to rendering to Flash.

My video recorder has a dv mini tape. When I import it into VS as type 1 it defaults to 720 X 576 and 16:9. Why is that? Is that wrong? The videos seem not to be distorted and are displaying in 16:9 and the video camera setting is to record in 16:9.
As to the unchecking of nonsuare pixel rendering - i did that because although I create an mpeg file as my final output, I then upload this to youtube and I believe it should be unchecked. Should my project properties be changed or output settings for the mpeg if I wish to uncheck that option?

Thanks

Not all the pixels are used in the frame and the 16:9 is letter boxed within the 720x576. So no it's not wrong

[dmz]

Thanks.
Im obviously missing some pieces of the puzzle. I tell my video camera to record in 16:9. Yet when I import it it says 720x576. Does that mean it is truncating stuff? And when you mention letterbox to me that means nasty black lines above and below or left and right but I dont get that. I seem to get the full 16:9 displayed on my widescreen tv without distortion or black bars. So how is that happening when it says 720x576?

Thanks

I am afraid you are getting yourself worked up over nothing. And you missed the central part of Trevor's explanation above. I will repeat it:

The pixels are not square but stretched to shape of 16:9.

To clarify this still further, this stretching is absolutely normal for video which is being burning to a display format like DVD. So the 'non-square' rendering is totally normal, and in fact required, for 16:9 format DVDs.

But if you are preparing video ONLY for display on other computers -- and after all, that is what YouTube is all about -- then you UN-check the non-square pixel rendering box.

If it makes it any clearer, for a DVD, think of wide screen as it actually is -- a rectangle, 16 x 9. That is definitely not a square. So you don't want square pixel rendering for that type of video, so you check the 'non-square' box.

But don't start asking about why 720 x 576 format pixels can ever be square!!!

[dmz]

Thanks Ken,
Its not really about being worked up, its not having a clear understanding of why things are the way they are.
So when I tell my camera to film 16:9 and I import to an avi file in VS that happens to say 720x576 then I ignore those figures as they mean nothing in practice.
As long as I say non square pixel rendering then my output will be 16:9 and even though the it says 720x576 in the output mpeg it means nothing. Its 16:9 all the way....
However,
as I discovered in this thread, if I dont do "non square pixel" then my text is misaligned and my photos are stretched.
So my final question is - if I want to output to mpeg then upload to youtube and NOT check the "non square pixel rendering" then what else do I need to do to ensure my text is not misaligned or my photos arent stretched?

Thanks

Hi David

Images are made up of rows and rows of pixels, that is how we perceive our photographs using square pixels.

For standard video the pixels are rectangular, in order to achieve this shape the square pixels are stretched horizontally into a rectangular shape. This process being known as Non Square Pixel Rendering.

Standard Pal 4:3 video size is 720 x 576, just to confuse things this is not 4:3. I know you thought it was, but its not. (a calculator may be needed here)
The square pixels are stretched a little to form a 4:3 shape (768 x 576 is the standard Pal 4:3)
For widescreen the pixels are stretched further to form a 16:9 shape (1024 x 576)
Having been recorded by your camera in this form will display correctly.

Ok
First make sure Non Square Pixel Rendering is selected.
Then from File-Preferences-select Show Messages when inserting first Video

Capturing from a Mini-DV type camera should be done via firewire selecting DV as the capture format. This saves the video files to the working folder as DV-Avi (13 Gb per hour) and inserts the captured files as thumbnails to the timeline. An info window should show prompting you to match/change the project properties.

To test this Start a new project and insert one of your captured clips to the timeline, from the info window select “Details”, the info in the right panel shows your video properties.
Selecting yes/ok will change the project properties to match

Your video should view as ok, not distorted.
X2 shows the preview background as transparent (grey squares) so what you see is your video frame.

Edit your project, then Share Create Video File-Same as First Clip. This will create a Dv-Avi of your movie, effectively setting your images, video, titles in position.
However if you were to render the project to the internet format then you may experience alignment problems as you have found earlier.

Use this new Dv-Avi in a new project to convert to your desired internet format.
Again your images and titles will be displayed ok.

Some internet format may not require Non Square Pixel Rendering,
Creating a Flash file may result in a black border, this can be overcome by disabling Non Square Pixels.
Not all video formats use NSPR and it can be confusing.

High Definition 1920 x 1080 is true 16:9 and does not require Non Square Pixel Rendering.

[dmz]

Thank you for your detailed reply. I now get how 16:9 is achieved.
I capture my mini-dv videos using firewire and DV (type-1) as you suggest.
When it says to set the properties to match the video I say yes. Hence my project properties as mentioned earlier.
To create the mpeg file I now know I have to select non-square pixel rendering so the output is correct.

However, Im still not sure what I have to do to retain my text alignment and not stretch my photos if I want to create an mpeg and NOT select non-square pixel rendering.
Why do I need to do this? Because some videos are to be uploaded to youtube. I could output the file as avi but that is way to large a file to upload so I create an mpeg instead. But as its being uploaded to youtube Im not supposed to check "non-square" but then the resultant mpeg text and photos are misaligned. Is there maybe another format I can output which would create a small file good for youtube?

Thanks

David

FWIW, I have never unchecked the non-square pixel rendering for my uploaded videos and, as far as I am concerned, they look fine.

Have you tried it?
