Can anyone tell me if there is a "maximum" file size when it comes to placing graphics in Captivate?
When I create graphics for my Captivate projects I always create a template in Illustrator or Photoshop and I build my graphics to scale. I then save for web as .PNG.
Is there a general rule of thumb regarding image file sizes?
I've not encountered one, and I've had to edit large background graphics (1024x768) and tend to import them back in as BMP (the wisdom of doing that as opposed to JPG or PNG can be debated).
Just note, everything you add to your CP project makes it larger - and including audio and custom images will probably have the biggest effect...so as always, just keep your images as small as possible (in size and dimension).
CP can scale quality images pretty well, so there's a tempation to bring in large and scale down. I'd avoid that where possible.
But all that said, I dont't recall CP ever preventing me from importing an image because the file size was too big...but I've never tried to really push it either...
Ok maybe I need to start from a different angle.
I have a co-worker that has created a Captivate 5.5 program that was 150MB. (huge)
We run these from our web-based intranet.
and of course we are having playability issues with this project.
The library is filled with 227 images, have of them are 10mb or more!
I inspected the file and found that these images are high-res 5100x.... and just resized in Captivate. (yeah, crazy...I know)
I encouraged the designer to go in and resize/scale/resave/replace as many images as possible to bring down the file size.
She has adjusted many of the images now the file is 137MB still huge. I think she needs to go back and resave her images even smaller.
What can we do to shrink this file?
I have gone through the forums and have found that some users say they have large Captivate files (50MB) and they essentially "copy" the slides from one to a blank project, resave and the file is like 2MB!!
How does this happen?
I tried this with the 137MB file and got another 137MB file?
In looking at library, not only is there about a GB of images bring used, the audio file sizes appear to be on the rubust size as well. The audio files range from 400-9999k.
The majority of the audio was recorded directly into Captivate.
Captivate seems to 'remember' assets that were deleted sometimes, resulting if files that are larger than they should be...and are often fixed by the copy/paste method you've read about - and that's not guaranteed to work, as you've found. It would be nice if there was a more official 'save and compact' feature as there is/was with other products.
Be sure to click the 'find unused objects' button in the library - finding and removing those unused items, then at least doing a 'save as' can help reduce file size by alot.
You can set the recording properties of the files you record into Captivate, but that's not as critical as the format you publish to. Look for those audio publish settings. If it's just narration, you can probably reduce the default quality a bit to save published size...
Images, you can do the same...reducing the published quality. But you'll almost always surely get better results if you optimize images outside CP...
I Agree with Erik.
Copy and paste is not the correct option for you.
If you have heavy images and audio, and you are facing playability issues, then you need to either reduce the file size of the original images and then insert them again, or you can change the publish settings to low and then publish the output. Both the things will give you output which low in file size, and so in the quality.
we tried setting thew SWF to low and that gave us the "audio in a can" effect.
looks like we will have to essentially reset/scale/size all the images.
The program is designed to be in two parts. With the first being 50 slides and the second about 20. I guess I could link the one to play off the other (daisychain)?
If not delivering via LMS, such 'daisy chaining' is possible - see this thread for a long discussion that would surely cover most any question you have on the process;
Or use the 'Aggregator' product that comes with Captivate...
But if delivering via LMS, while you might be able to do such linking, it may not work well and it certainly would not track the status/progress of both lessons...
IF to be delivered via LMS, probably better to just publish two separate lessons.
