Question

Shadow lines on seen on slides / screen of published captivate project

Dear Experts,

We have recorded a screen sequence in higher resolution. After publishing the project and playing the video, we do observer shadow lines on some of the screens. This is happening consistently for all the projects we have published so far.

We have verified the suggestion of turning off Advanced Project Compression in Preferences > Project > SWF Size and Quality. Even with this suggestion we still find the shadow lines appear after re-publishing the video and playing it in a web browser.

The problem is seen, even when we use the same resolution that was used to record the project.


We also have a requirement, where users will play the same published video on different screen resolutions (LCD Wide screen 16:10, 16:9 or 4:3, or even Laptops screen)

Need a resolution for this project at earliest. We need to send this out to our front office and in current state it is a major negative impression.

Thank you!

Ravi

Thank you, I do understand the reason of distortion or degradation. But then I do see the problem of Shadow lines appearing, even if i am viewing the content at same resolution as what i used while published it.

Hello Erik,

Thank you for your response.

  1. I have not resized the project, nor have i published it at different screen resolutions. It is one of the requirement, where end user may see same video in different screen resolution or devices and still it should not be distorted.
  2. The capture and publish operations are not happening in parallel. We are doing the publishing only after the capture and audio import is complete. Both Capture and Publishing is done on same machine but in sequential manner not parallely.
  3. Like i said i am doing a publish on same machine and have not tampered during the capture or publishing.

Regards

Ravi

If your end users are viewing the content on devices with different screen resolutions then it IS being resized, and that's what Eric was pointing out. Resizing the content (even if it is being done at runtime) will often cause degradation of the content.

Have you resized the project? I've seen this in previous versions most frequently when the original recording was resized, and/or when compression was high (which you said you turned off).

Try a sample capture on another computer? Try publishing the project on another computer?

The video card the computer has is heavily involved in the capture, so that can affect the quality... I don't think it would affect publishing but can't hurt to try a different machine for publish, just in case.

Similarly, is your screen color depth the same setting during edit/publish as it is during capture?
