Whenever I get a client that wants me to convert video for powerpoint on a pc.
I always give them a windows media file.
If it’s SD the size is: 640×480 30fps
If it’s HD the size is: 640×360 30fps
In final cut pro I export with quicktime conversion and do the resizing there (looks better that way) then convert it with compressor. I have the flip4mac .wmv plugin.
never failed me or my clients yet…done lots of them.
