The most important thing is resizing the videos. I have to upload them. And with this script the size is between 1/8 and 1/12 of the original size. A bonus is that I put a copyright into it. >> -crf 26 \ > > This reduces quality - which is indeed good for size. Is the quality > still good enough for you?

But it took just to much time, while the difference was not that great. I do not have to convert much often, but previous weekend I shot a lot of videos and even with this preset it took a lot of time. (I do some timings an share them later.) But there are no glaring mistakes then? ;-) -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
