Re: [Motion-user] jpg Conversion to mpeg

[Chris H. <mo...@de...>]

Hi Artur

Thanks for the script it was what I was looking for.

I note on my PC that it takes 0.1 sec on average to convert a frame (1200
frames in 2mins) so it is not really practical for me for on the fly
conversion but fine for cron jobs. I also notice that there are quite a
few artifacts visible which presumably is normal for this conversion to
AVI.

cheers

Chris
