I'm running Mountain Lion and just downloaded 2.6.4 Moutain Lion 64bits (tar.gz) from the avidemux site.
I used to use an older version on snow leopard for cutting mpeg-1 from a video capture card, and then encoding it using an mpeg 2 encoding algorithm.
Now, when I select mpeg 2 and try to save video only, the encoding status displays no info. It eventually saves a file, which had some edits, but the end of the video is missing.
Any ideas? Thanks
