I've captured some video using iShowU for my own personal use. I can tolerate a quality level that is less than the original capture.
I end up with iShowU files that are 700x400, apple animation, AAC.
I noticed that some files are surprisingly large ( 30min = 980mb, 21min = 900mb, but then there is a 7min = that is 971mb ).
Looking at the GetInfo, I see that the bit rates vary a lot. The 7min capture ended up with a bit rate of 16,898 ! vs 4200 for the 30min capture.
Questions:
1) I assume higher bit rate is causing the file size to be bigger than it needs to be. But I did not change any settings in iShowU. How can I specify a lower bit rate before recording?
2) Is there a good way to compress these large .mov files further so they don't take up so much space ?
