mp4 video help?

Question

I have a mp4 video that is 653 MB...is there any way to make it smaller? Much smaller...probably no more that 200 MB without loosing quality or sound or whatever?

Answer 1

Not really, but depends. There is no such a thing as unlimited compression with no side effects.

H.264 is one of the most efficient codecs. So here is what you can check:
a) The bit rate of your video (2 Mbits/s)
b) The picture resolution (say 720x480)

To make it smaller you need to do at least one of the following
- Reduce picture resolution (the decoder will scale up, but up to a point)
- Reduce bit rate

No matter what you do you will lose picture quality.
