I will be preparing a number of short movie clips featuring different pieces of
equipment and their use; eg FT-IR, sample preparation, sample compartment, instrument
appearance and typical spectrum, etc.
I have now revised my opinion of how useful the Web server here in Jamaica can be as a source of video clips. From the log files, it is obvious that only a limited number of North American sites can receive the files and that most others abort the download or time out. Over the next 12 months I will be attempting to produce CD's containing these files instead. So I hope I can count on you purchasing them!!
My first attempt at video capture was prepared at The University of Leeds some time
Thanks to Jon Maber (it is his hand) and Dr. Andrew Booth.
They have created some excellent examples of .AVI files, which can be found at the Bionet site in Leeds.
Again, thanks to Jon Maber who wrote the software used in creating the following
An overly simplistic view of the chelation of 1,2-diaminoethane by replacement of bound ammonia groups-1.7 MB. Further details on CHELATION can be found here.
The following files show rotations of simple molecules, such as caffeine.
If you are interested in seeing more on coffee and caffeine then look at the section from here.
A clip showing the relationship of octahedrally coordinated groups to tetrahedral groups can be found here -300 KB.
I have tried out a conversion procedure between avi and mpeg files and the results can
be seen by comparing the following 2 files.
The first was produced as an 8-bit avi Caff1.avi- rotation of caffeine molecule while the second was converted from it using "cmpeg", details are available from here. It is called caff1.mpg and is ~194K.
The conversion required ripping a 24-bit avi (this meant the original 8-bit caff1.avi file had first to be converted to 24-bit which expanded it from 200K to 6.3MB) into the 64 frames of bitmap files in targa format (again this took up about 6.4MB) then converting to MPEG.
I chose only the default values and have not experimented much, but judge the quality for yourselves! I guess I need to work on the palettes before converting from the 8bit avi to 24bit avi?? Please let me know if you have seen any other conversion methods.
Other chemistry related movie files (largely for Silicon Graphics, but some MPEG) can
be found at Darmstadt.
MPEG and Quicktime files can be found at Virginia Tech.
