16th Scientific Meeting &
Computer Projection Instructions
General PowerPoint Slide Guidelines:
In order to make organization easier, please use your last name-01, 02, 03, etc. when naming additional files, such as movies or sounds (smith-01.mov, smith-02.avi, smith-03.avi, etc.). This will need to be done before importing them into PowerPoint. The number need not reflect the order in which the movies run in the PowerPoint presentation.
When importing or inserting any graphic file (picture) it is important to make sure that it will function on any computer and does not require proprietary software to view. The acceptable formats are as follows:
Bitmap (BMP), GIF, JPEG (JPG), Portable Network Graphic (PNG), and TIFF (TIF).
While Microsoft PowerPoint may allow other formats to be imported, compatibility cannot be guaranteed.
Macintosh users who use a PC for presentation should follow the above guidelines as well. While Apple Operating Systems and Microsoft Office for Macintosh allow PICT files to be imported, they often fail to function when viewed on the PC.
Lastly, computer displays and projectors generally display at 72 to 100 dots per inch (DPI). Graphic files should be adjusted to these parameters. Since many scanners use resolutions of 300 DPI or greater, a program such as Adobe Photoshop ® can be used to reduce the DPI to the 72 to 100 range. This is done before importing the picture into PowerPoint. Failure to reduce graphic files creates large PowerPoint files with superfluous data.
It is especially critical that any presentation that uses videos be loaded at least 24 hours in advance. Video files are not embedded, so a copy of the actual file must be included with the PowerPoint presentation.
The most common cause of videos to fail is a lack of a compatible compressor (CODEC).
MPEG1 (.MPG) videos are the most universally compatible, but tend to lose some image quality.
If .AVI or .MOV files are used, please follow the below guidelines:
The following are acceptable CODECs to use for .AVI files:
· Cinepack, Indeo v 3.2, Microsoft RLE, Microsoft Video, and none/uncompressed.
The following are acceptable for use with QuickTime .MOV files:
· Cinepack, video, and none/uncompressed. While PC PowerPoint will allow the importation of QuickTime files, in order to assure compatibility it is recommended to convert them to AVI or MPEG1 files.
DO NOT USE DIVX or any other NON-STANDARD CODEC!!!
The following parameters will help ensure compatibility in the above video formats:
· Size not to exceed 352 x 240 (DV pixel scheme) or 320 x 240 (square pixel scheme).
Frame rate not to exceed 15fps. Audio not to exceed 16 bit 44k.
