Question

Looking for ideas to keep published file sizes down for lower bandwidth connections.

It looks like CP5 keeps the original images intact and visually scales them so if you place A 4000x3000 pixel, 3MB image in a 800 x 600 pixel project, the project file size increases by 3MB not the smaller needed image size.

Are mono audio files smaller than stereo? What to good, low settings?

What are good settings for 640 x 360 FLV videos?

We got the project to work. Now we need to knock the size of the files down considerably.

Any and all ideas appreciated.

    Hello,

    I hope that I understood your question correctly?  First want to emphasize that for the bandwidth it is not the filesize of the CP-file that is important, but the size of the published SWF. The imported image will have its original size in the Library. But in the published SWF, where graphics and audio will be compressed, this is not important anymore, since the compressing will have been done on the size of the image on the stage, which in your case is smaller than the original image. Same for audio: in the Library you will find a WAV-file for the audio assets, but after compressing (in the SWF) they will be MP3.

    There are some threads in this forum where number of solutions were assembled for reducing filesize. For the audio assets (normally mono will be smaller then stereo assets, not mentioned in this thread because it was about CP4), perhaps have a look at this one:

    And for reducing filesize in general:

    Hope this helps,

    Yes. Looking to reduce file size for the published files--the SWFs--so it can malay on a slower connection with lower bandwidth.

    In my tests on the Mac version of Cap5, if I place a large 4000 x 3000 picture and scale it to fit 400 x 300 pixels, it is still published at 4000 x 3000 size. I was HOPING Cap5 would auto-magically resize the image to its needed pixel dimensions, therefore reducing the file size. JPEG compression settings do little since in the published SWF, the image is still the same larger dimensions. I verified this using FileJuicer which extracts whatever it can from various file types. The image is extracted at full size.

    Hi,

    I would suggest go to menu "Edit > Preferences" and select category "Project - SWF Size and Quality"

    Change the settings to different levels Low / Medium and publish your project and check the SWF file size.

    If you select the setting 'custom' then you need to do all the settings manually.

    Few points:

    1. Audio is by default published as MONO in captivate 5. This keeps the audio size within limits. (this setting can be changed in 'Preferences dialog - Publish setting'

    2. If you select 'custom' setting, then lower audio bitrate by going to menu 'Audio > Audio Settings'

    regards,

    I will try to answer the video (FLV) part:

    1. FLV videos when added to captivate is always external to the final SWF. So this doesnt add up to the size.

    2. Still it is always good to keep sizes minimum as your users need not download the large video when viewing. This link can help you in generating ideal FLV files Adobe - Flash application: Flash video (FLV) bitrate calculator
