Title: green line and poor JPEGs quality problem
Post by: fistania on March 11, 2013, 03:28:22 PM
hello, i'm new here so excuse me if i post in wrong place :)

i like using avidemux to make gifs, and the video is from the screen recording i use from quicktime, Mac Lion.
the dimensions of the video varies, and the thing is that sometimes there is a green/yellow line at the bottom of the video, and i noticed that each time there are green lines, the JPEG quality really drops so i have to save the frames one by one by saving as BMP images.

is there any solution for this? i've read a thread about green line before, but i don't understand the solution since i'm not really good with programs and stuff, so please kindly explain it in a language that is easy to understand  :D

thank you.

It's because the width/height are not multiple of 16
crop the bottom/right part until you have a multiple of 16 and it will be fine

thank you for replying!

you mean like 160x160, 320x160, 160x176ââ,¬Â¦ like that?
is it possible to edit/crop video dimensions on avidemux?

Normally, when video is loaded and you select Video Output. In filter you would find crop or resize filter.
