> When using ffmpeg, the default video bitrate is _insanely_ low,
> 200kbps or so iIRC. Use -b 800000 (bitrate is in bps not kbps) or

>> Hi,
>>
>> For my study I use a piece of software that displays animated 3d models
>> and which can generate images for each frame of the animation.
>>
>> I can make these image into an animated gif using ImageMagick's convert
>> or into an mpeg movie using ffmpeg, for use in a ppt presentation.
>>
>> The mpeg has lots of compression artifacts (I guess because the images
>> are computer generated they have sharp colour gradients). The animated
>> gif looks  great, but is quite a large file.
>>
>> There must be a way to make an movie that doesn't have the compression
>> artifacts as is done for screencast type movies.
>>
>> I've done some web searching about this but I'm not sure what I'm
>> looking for. Can anyone suggest a way to do this or some search terms
>> that I could use?
>>
>> Cheers
>> Glenn
