Publishing Adobe Captivate Videos on YouTube

The easiest way to do this is to use Adobe Captivate 4 and a video processing application such as Virtual dub. Adobe Captivate 4 will publish your projects as AVI files, which is a marked improvement on previous versions.
However the AVI files produced from captivate are huge - uploading them to YouTube can take several hours unless you have a hardcore Internet connection.
Also, the quality of these when viewed on YouTube can be very poor. YouTube re masters the videos uploaded to it, to save its hard drive space – if you give it a large video file, it will re master it. And sometimes, not do a good job at all.
The best way to stop your videos being massacred as much is to remaster the video yourself - reduce the file size as much as possible and set the video resolution.

To remaster your Captivate AVI, you can use a program like Virtual dub.

I found that resizing the video to 640 x 480, compressing the audio, and recompressing the video vastly improved the results on YouTube.
To give you an idea of file size difference, a “raw” AVI file I produced in captivate (at 1280 x 1024 res) weighed in at 3.5GB.
After processing in Virtual dub, the file size was 152MB. Even taking into account the resized version had ¼ as many pixels, it’s a huge saving.
To test, I uploaded the original version and the virtual dubbed version to YouTube. I tried this with several videos. The original video had missing frames and artefacts; the processed version was much clearer, with no missing frames and minimal artefacts.

Recommended settings for Virtual dub remastering

  • Resize video to 640 x 480
  • Set the video compression to Cinepack Codec by Radius (you may have better Codec installed)
  • Set audio to “Full Processing Mode”
  • Set audio compression to MPEG Layer 3, 64KB/s, 44.100KHz, Mono

c) Set the video compression to Cinepack Codec by Radius (this is an old and creaky Codec – others may work better!)
This is done by selecting “Video” > “Compression” > “Cinepack Codec by Radius”

Introduction to sitemap.xml

Checking for a sitemap A site map (or sitemap) is a list of pages of a web site accessible to crawlers or users. It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, Some developers feel that site index is a more appropriately used term to relay page function, web visitors are used to seeing each term and generally associate both as one and the same. However, a site index is often an A-Z index that provides access to content, while a site map provides a general... Read More »

Center a web page in CSS

One simple way to center a web page using CSS is to create a container div, that is horizontally centered by having its left and right margins set to auto. Using this method, you can still apply colours / background images to the body tag, so its a flexible solution. (if you didnt need this ability, just apply margins and width to the body tag instead, and forget using the container div). The container div has the same width as your webpage and, well, contains it. All the code for your web page is placed inside the container div. This will... Read More »
