3.2. Preparing your image and audio files
Image files must be JPEG files, and must have a ".jpg" or ".jpeg" file extension. Images must not be progressive JPEG files.
Soundslides and Soundslides Plus can import any image sizes, and will resize the images to fit the size of the final slide show automatically.
After selecting your images, copy them into a single folder for import.
Soundslides and Soundslides Plus can read the IPTC caption information from JPG files. Many photographers choose to add their captions before importing the images.
Your images should be at least as large as your slide show output dimensions. For example, if you are creating a slide show exported at 800 px by 600 px, you would need to import images that equal or exceed those dimensions.
A word about color profiles
If the images in your slide show appear too pale or lacking in contrast, or if they appear vastly different than they do in your image editor, color profile settings may be the reason. Soundslides and Soundslides Plus can handle any color profile, though "Generic RGB" or "sRGB" is preferred, as these most closely match the colors used by the Flash Player in your users' Web browsers. If you are using Adobe Photoshop, select "Convert to Profile," then select "Generic RGB" or "sRGB."
Advanced workflow example
Here is a workflow that is in use at several media organizations:
- Tone, crop and caption in Adobe Photoshop.
- Set color profile to "sRGB."
- Size images to 1000px (longest dimension). If outputting to full-screen, use 1280 or higher.
- Sharpen lightly if necessary.
- Save as JPEG at quality of 12 or "Maximum" in single folder.
- Import folder into Soundslides or Soundslides Plus.
Adobe Flash Player requires that audio files be 16 bit and have a sample rate of 44.1 khz (44100 hz).
Flash Player can handle MP3 files encoded at 32 kbps, 48 kbps, 56 kbps, 64 kbps, 128 kbps, 160 kbps or 256 kbps. For optimal audio streaming over a wide range of broadband connection speeds, we recommend a bitrate of 128 kbps.
Combining or editing audio files
Soundslides and Soundslides Plus do not edit audio, so you'll need to edit the audio in another application and create a single file before importing. This is fairly simple to do.
If you don't have an audio editor, Audacity is a free, open-source editor for Mac OS X and Windows.
