QuickTime 7 Pro: H.264

The Pro version of Quicktime allows you, among others, to compress video files in H.264 format with excellent quality.

Tutorial requirements:
- You must have Flash QuickTime 7 Pro installed in your system.
NOTE: The user interface of the following screen captures may be different than yours, since it depends on the operating system your are using (Windows XP, Vista, Mac OSX, etc).

To go directly to the recommended settings table click here.


1. Open the source file with QuickTime Pro.
Check out the file formats supported by QuickTime in this page: http://www.apple.com/quicktime/pro/specs.html. .
NOTE: We recommend to use a source video file with the highest possible quality.
2. Go to "File" / "Export"



The export window will open.

In this window select the destination folder and file name for the resulting file.
NOTE: We recommend to include the quality as part of the file name, this way it will be easier to identify it when you are ready to upload it to your WebTV.


Then click on "Options": the "Movie Settings" window will open.

In this window you will find an overview of the compression settings.
VERY IMPORTANT: The first thing we have to emphasize (in red) is the "Prepare for Internet Streaming" option, the checkbox must be ticked and "Fast Start" must be selected.

Please, pay attention to all highlighted zones (in red). We will present you screen captures of every window and, at the end of this tutorial, you will find a table with recommended values for all the compression parameters.

The highlighted zones are:
Video
1 - "Settings"
2 - "Size"
Audio
3 - "Settings"

1. Video: "Settings"

Select the options indicated with red arrows.
- (??) "Frame Rate": select between 25 fps (PAL) or 30 fps (NTSC).

VERY IMPORTANT: Don´t forget to select "Streaming" in the "Optimized for" drop down menu.
Click on "OK"


2. Video: "Size"

- Drop down the "Dimensions" menu and select the last option "Custom", this allows you to enter values at the right ??? x ??? ( width x height ).
NOTE: For width and height fields, use the values from the table you will find at the end of this tutorial.
- Tick the checkbox "Deinterlace Source Video" if your source video is interlaced.
NOTE: Usually, videos are "Interlaced", if you are not sure, it is better to leave the checkbox ticked.
Click on "OK"
