wow! I just got around to trying that a couple of days ago and it |
17 |
produces great output: fast, small file size, and no noticeable |
18 |
difference in quality between the mpeg and the original dv! (I watched |
19 |
many different clips many times over to make sure! on TV and on my LCD) |
20 |
|
21 |
But: the mpeg doesn't seem to scale right. My laptop display is |
22 |
1680x1050, and hence the original dv output (4:3) has black edges on |
23 |
each side, but the converted mpeg plays "stretched", so that everybody |
24 |
looks fat! |
25 |
|
26 |
Is this just a _player_ issue, or is it a problem with the encoding of |
27 |
the mpeg itself? |
28 |
|
29 |
I noticed the command line has aspect=4/3 in it already, which is the |
30 |
aspect of the original dv file... |
31 |
|
32 |
many thanks! |

The first 90% of a project takes 90% of the time, the last 10% takes the |

other 90% of the time. |
