Compressing PowerPoint presentations
Attractive and effective PowerPoints are usually pretty bulky in size and thus not very convenient to upload to the Internet, send via email or otherwise distribute.
Trying to make PowerPoint files as compact as possible, people compress photos on their slides or use numerous software tools for compressing presentations. This way they surely make presentations a little smaller, but they don't really make them any more ready for sharing and delivery. They will still remain good-old PowerPoint files that have to be downloaded in order to be played. And after they are finally downloaded and you are ready for the show to begin, they start giving you troubles: PowerPoint versions incompatibility, incorrect fonts rendering, lost linked audios, videos, tables, diagrams and other objects...
There is a solution for the problem - convert your PowerPoint file to Flash. Your presentation will look exactly the same, but it will be much more compact and, more importantly, easy to deliver and web-ready.
iSpring Pro PowerPoint to Flash converter uses iSpring AccuPoint technology, which makes sure that all the media resources inserted in your slides are compressed, but look and sound just as crisp as they did in PowerPoint. Although it makes your presentation much smaller, iSpring still accurately re-creates all the PowerPoint animation and transition effects and makes them work in Flash just as beautifully as they did in PowerPoint.
Unlike many other PowerPoint to Flash converters, iSpring only creates a single .SWF file, which is a great advantage if you are going to share your presentation.
"Smart" Image Compression
"Smart" compression is a unique image compression technique. It optimizes the size of your presentation striving to provide the highest quality of image content.
Images can be stored in Flash format with "Lossy"(JPEG) or "Lossless"(PNG) compression. "Lossy" is the most appropriate for photos and realistic images. This compression type allows decreasing the image size up to 10+ times with insignificant quality losses. In case you use diagrams, sketches, charts in your presentation, it's better to apply "Lossless" compression which converts images with the highest quality.
Since a presentation usually contains various types of images, iSpring offers "Smart" compression. This unique technique analyses each image, automatically determines its type and chooses the best way of saving it in Flash format. This helps to keep the quality high and the size small.
Audio and Video Compression
By default, iSpring preserves the original audio quality. You can set a higher or a lower bitrate for lower file size, but it will also affect the audio quality.
iSpring sets 600 KBit/s for video in your presentation by default. If you want to publish your presentation to web you may need to reduce the file size with minimal quality losses.
Compression Presets
With iSpring compression presets it’s easy to save and quickly apply the same compression settings to similar projects. Plus, you can create up to 10 custom compression modes that will fit your personal requirements the best way.
Detaching Media Content
This feature allows you to save audio, video or embedded Flash as an external attachment to the output Flash presentation. It improves conversion of presentations with large Flash, audio and video attachments.
Any Flash file can contain no more than 65536 objects. This limitation was set by the creators of Flash format and you may read more about it here. When converting a presentation with embedded video, the output Flash file may exceed the limitation. Saving multimedia files separately from Flash presentation allows converting large presentations and results in the higher quality of embedded resources and higher speed of conversion.
Try converting your PowerPoints to Flash with iSpring and learn for yourself how great of a compression method that is. No more struggling with huge files and complicated compression software. Flash format is really the most compact and neat output for your PowerPoint creations.
