Question

Full Motion Video - memory leak?

Good afternoon.

I am using captivate 1.01.1418.1418 to record and present standalone demos of rich client web technologies. The default capturing techniques just don't cut it, so I need to record the entire demo in full motion video.

What I have noticed is that when you edit the video AND ALSO when running the published demo using either stand-alone or swf object methods that there is a huge memory leak. I am talking to the magnitude of 20-25 meg / second while displaying full motion video.

My latest presentation is 22 slides where 3 of them are short full motion video clips recorded at 1024x768 with no audio. The clips are between 30-90 seconds.

The generated output exe is 6 megs and if I generate it with all compression off it is 11 megs. When I run it, my memory usage goes to 1.7 GIG of Physical Memory and over 2 GIG of Virtual Memory in use. The movie playback then turns solid red and my machine hangs up until I can manage to kill the playback.

Is there a known issue with full motion video and memory leaks? I can understand if it took more memory to run it, but using 3+ gig of RAM to play a 10 meg file? Something sounds off to me.

I had purchased this product to record and display full motion demos and so far it has not been able to meet the needs it promised to deliver.

Any help anyone provides is greatly appeciated.

Please respond here and/or email me at lavoie_ray@hotmail.com.

Thanks in advance for your time.

P.S. I remember seeing the same behavior on my trial version of Captivate 2, however, my trial has expired and I cannot see if the leak is of the same magnitude.

    Hi Ray,

    You are experiencing "normal behavior" for the use you are putting Captivate to. It was never designed as a full motion video capture tool. I won't argue whether or not the marketing people ever said it was capable of doing what you say you bought it to do, but I really doubt they would make a claim that everyone knows is not true ... if you can find something official from Adobe asserting that, I'd sure be interested in seeing it.

    The full motion feature was intended to be used to demonstrate 2-3 second drag-and-drop operations, or use of a scroll bar action of about that duration. In addition, you stated you are capturing at 1024x768 size, which is an image of truly gigantic proportions - adding to the full motion load you are already throwing at the product. Could it be that another product is better suited for what you want to do? I'd consider that seriously because you are asking more of Captivate than I believe it can deliver on anything but a machine designed for 2015 processor speeds with infinite resources.

    It is especially sad that you own and used Captivate 1.0.1, then spent an additional 30 days using the Trial version of Captivate 2.0 ... but are just now finding it doesn't do what you thought it should do. Again, sorry for your trouble.
