Re: significant quality loss moving from 6.2 to 6.6..

Can you give an example command. I will then put that and your comment in the video formats area. This is what I used that I snipped from some other source online. It probably has extra options I don't need but it makes a nice time-lapse from .jpg files mencoder -nosound mf://*.jpg -mf w=800:h=371 ...

Re: significant quality loss moving from 6.2 to 6.6..

thanks for everybody's help - I'm going to delete download links to save bandwidth

Whoever is writing the docs for IM should just put under "video", "USE MENCODER"... wow it's like 1000 times faster and actually WORKS.

Re: significant quality loss moving from 6.2 to 6.6..

I can't find any examples of directly calling ffmpeg that work for me. It's installed on the system and apparently used by IM.

Re: significant quality loss moving from 6.2 to 6.6..

I tried using m2v: as in: convert ar1-*.jpg m2v:out.mpg

It still resulted in a 1.5MB crappy quality file

I'm stuck.

Is there an alternative to IM to use for something like this? I simply want to create a time-lapse video of approximately 400-500 jpgs that is of non-horrendous quality.

Re: significant quality loss moving from 6.2 to 6.6..

Re: significant quality loss moving from 6.2 to 6.6..

Re: significant quality loss moving from 6.2 to 6.6..

What would be a high-quality setting? I tried: -sampling-factor 1x1 and it didn't appear to make much of a difference.
