mp4 scaling??

  • Question
  • Updated 4 years ago
I'm using a screen with dimesions 2560 x 1600, and latest version of Camtasia.

My company's software is running in a window (using JavxFX on Windows 10) sized at 1920 x 1080 pixels. I have set Camtasia to use a custom area of 1920 x 1080.  I want the final video to be this resolution, to view via browser ... I just want to see the contents of this window, nothing outside this.

The first thing is that the outline border rendered by Camtasia is not the same size as the above window.  Close, but not exact.  The height visually agrees, but the wdith differs.  Camtasia's area is wider (the picture is only showing a section of my screen)




Next, I save the file, and uses "produce and share" to export to 1080p.  But I missed the fact that Camtasia had decided to reduce the editing dimensions for the above window down to about 66%, so the mp4 had a lot of black border space.  Suggestion: it would be useful if Camtasia set the size to match 1080p for export, not a scaled down factor.

So, I then changed the editing dimesions to 1920x1080, and now the mismatch in width mentioned above became more noticeable.  However, on again exporting as 1080p, when I watch the mp4, using various media players, the video always looks scaled down in size, and is not as clear to read as the original window contents.  For example, here's a snapshot showing the video playing in VLC and a noticeable size difference cf the original 1920x1080 window.  If I make the VLC window bigger, I just get more black background showing.



The video is the inner picture ... a lot smaller.

I get the same behaviour with Windows Media Player.

What do I have to do to get the same result as I originally recorded?

Thanks very much, Jerry

Hi,
Can you try something simple to see if it helps?
First, use the Lock to Application option when recording to see if this snaps to your exact recording dimensions. 

1. After recording, and you bring your video into the Editor, go in to the Editing Dimensions dialog box and change the setting to Original recording dimensions. You should see the options in the Width and Height boxes change to YOUR exact recording dimensions - even if they are off a bit.


2. Once you close that dialog box, you might see your video preview shows a huge or very small version of your video with black bars around it. Delete your video from the timeline and drag your video from the Clip Bin onto the timeline once again. It should perfectly fill the Canvas preview for you.

3. When producing your video, choose the Custom Production Settings option. You should see your exact dimensions in the screen. Step through the wizard to produce your video.

Now, you should see your finished video exactly as you have created it with now scaling at all and no black bars.

(Note: if you have a lot of text on your screen or other small areas your viewers need to see, you will need to use Zoom and Pan to increase the magnification of those areas.)

If this is not the help you needed, let us know and we can get you the help you need.

Jerry, 

If I measure your app window in the first screenshot you provided, I'm not coming up with 1920 x 1080. It's more like 1905  x 1070. So unless I'm misunderstanding, the first step would be to get that window to actually be displayed at 1920 x 1080.

One way to do that is to enable the 'Lock to Application" option in the Camtasia Studio Recorder Custom dropdown:



 
Then, you can choose the 1080p HD option and it should re-size your app to 1080p (although I can't say for sure without testing it on your specific app). 

After that, choosing the "Original Recording Dimensions" as your editing dimensions setting in Camtasia (as Kelly illustrated above) should ensure that your final video is the same dimensions as your recording.

Hope that helps, and thanks for posting.

Hi Kelly and Josh,

I've done the above, and things are a lot better, but still not quite right.

I've checked the documentation for JavaFX8, setting window size.  Here it is...



Notice any OS decoration is included in the size.  I'm using this, and the equivalent setHeight(), to set the dimensions to 1920x1080.

When I use "Snap to application", the border drawn by Camtasia is larger than the window size above (not by much).

After going thought the production process as suggested, and playing back through VLC, I get the following information from VLC about the codec.



Notice the difference between Resolution and Display Resolution.  I don't understand this, but is it something of concern?

Thanks, Jerry

(p.s I absolutely love Camtasia Studio ... wonderful tool)

Jerry,

We passed this around the office a bit, and we're really not sure why those dimensions don't match.  Would you be willing to open a ticket with Tech Support, where they can take a look at your files?

If so, use this link: https://support.techsmith.com/hc/en-us/requests/new

And also maybe include a link to this thread when you open the ticket.

Thanks for posting, and sorry I couldn't be more helpful.
