Impatica for PowerPoint is a software solution that compresses and streams PowerPoint files for the web. Northwest MO State University has one copy of this software located in the CITE Office. This presentation will explain the process of narrating a PowerPoint presentation and how to have it converted with Impatica.
The first step is preparing your PowerPoint presentation. If you know in advance it will be converted with Impatica, then remember to keep it simple when developing. Use common fonts and simple backgrounds. Links and builds do work. Impatica supports most PowerPoint features, but there are a few it does not. For a list of supported and non-supported features, see the Impatica User Manual.
You will need a microphone. A computer built in microphones usually pick up the hum of the computer. For best capture use a Head Set Microphone. These can be purchased at most places that sell electronics. All kinds and levels of prices. Usually 10-15 dollar microphone will work. The better quality microphones will cost more and the best usually have a USB connection. Connect the microphone to the dedicated Microphone port. Sometimes it is color coded. Pink is for the microphone. In its absence use the Line -In port on the computer.
Now you have your equipment to narrate your presentation. The next step is the script. Place script needs to be placed in notes field of each slide in the PowerPoint file. This is important for 2 reasons: Impatica will supply a notes file which makes the presentation on the web ADA compliant. Any viewer that needs a text reader will be able to use the notes. By law this is now mandatory. Also you can print out your Notes pages before recording to have script while recording.
Now you are ready to record your narration. I will demo this using PowerPoint 2003. To narrate your presentation go to the Slide Show menu and select ‘Record Narration’ as shown here.
Selecting Record Narration will open this dialog window. You will automatically see the current recording quality. Since Impatica will compress the sound, there is less distortion in the compression process if you record at the level it is compressed to. So click ‘Change Quality’ to open the Sound Selection window. Select PCM (which is a wave file) and then select 8000 kHz, 16 Bit, Mono. - 15 kb/sec from the Attributes drop down box. To make this easier in the future, click ‘Save As’ button and save the format as Impatica.
Now check and set your microphone recording level by clicking the ‘Set Microphone Level’. This pulls up the Microphone Check window. A green level bar will be visible. Speak or read into the microphone. This will automatically adjust the volume level of the captured sound. When speaking the level should mostly be green and just touching the yellow. If you see the level showing red, adjust the volume level down. Click OK when set.
In order for Impatica to work correctly, the narrations need to be embedded into the PowerPoint slides. Therefore do not use ‘link the narrations in’. Keep this unchecked. Click OK to begin recording
Recording happens in Slide Show Mode. Speaking into the microphone, narrate the presentation as you advance through the slides like normal (use the down arrow button or the mouse click to advance.) Use your notes to follow your script.
Try not to speak while changing slides, if you do some of the sound will be cut.
At the end the of the presentation the an information window will ask whether or not the timing should be saved? This is a question on how you want the presentation to run. Save will save the timing so the presentation will automatically forward itself through at the same timing as when recording. Don’t Save will not save the timing of the slides and the viewer will have to manually advance to each slide. This is your choice.
View the presentation to hear your recording. If any one slide needs rerecording, then go to that slide and again select Slide Show menu and click Record Narration and set up as before and click OK. You will be asked to start the recording at the current slide or at the beginning. Choose current. Record the slide or the next several. Click Esc when finished.
Save the presentation or use Save As to save a second copy with the narration. A saved narrated PowerPoint presentation is usually quite large in size. To big to email or to post on the web. The presentation now need to be brought to the CITE office to be Impaticized. Bring it in on a flash drive or burned to a CD. Or call the CITE Office to learn of other ways. A faculty or staff member can use the network.
Impatica conversion process will create 4 new files. The ‘title_of_the_presentation.html’, ‘title_of_the_presentation-notes.html’, ‘title_of_the_presentation.jar’, Implayer400.jar. Link to the html files to play the presentation and view the notes. Compare the size of the ‘title_of_the_presentation.jar and the original PPT presentation. The size will be much smaller.
If using an eCompanion course site, then I can upload these presentations to the course site and help in placing the link to view.
