Get VirtualDub. http://www.virtualdub.org
Open your video file in virtualdub. Click on audio. Click no audio (this is needed, since if the video plays in slow motion, the duration of the audio won’t match). Then click video. Click direct stream copy (so the conversion is lossless). Then click video. Click frame rate. Under 'source rate adjustment' select the 'change to [blank] frames per second' bullet and type in a frame rate (smaller than the one on the line above it, obviously). Then click file, save as avi, and you’re done.
Yup it’s work, but not working as I was think:( This is only reduction speed frame ratio. Do you know some freeware soft which can made slow motion, like for example realviz retimer? This is true slowmotion!
I’m getting an error:
couldn’t locate decopressor for format “cvid (unknown)
VirtualDub requires a Video for windows (VFW) compatible codec to decompress video. Derctshow codecs, such as those used by Windowa media player, are not suitable.
not sure where to go from here
to be specific, when i try to open the 9kb file, is windows media player says 'Windows Media Player cannot play the file. The file is either corrupt or the Player does not support the format you are trying to play.'
