Output Format

1. WMV format: No need to install additional player on your Pocket PC. Windows Media Player can play it directly. Recording is a little bit faster.

2. AVI format: Compress more. Provide better video quality than WMV format under the same output size. Need to download additional AVI codecs and players from http://download.pqdvd.com/

AVI format supports 1-pass encoding and 2-pass encoding. Both provide better quality than WMV format(WMV8). 2-pass encoding is explained later in this page.

Video Settings for Pocket PC

Crop Mode:

The standard resolution of a Pocket PC screen is 320x240. Its aspect ratio (width:height) is 4:3. However, different video sources may use different aspect ratios (e.g 4:3, 16:9, 2.35:1). Both 16:9 and 2.35:1 are widescreen, however 2.35:1 is even wider. Some DVD movie with 2.35:1 aspect ratio contains black bars on top and bottom in order to fit into 16:9 DVD standard. For 2.35:1 extra wide movies, you may choose the following crop modes based on your personal preference.

Crop mode 1 Cut off the top black bar, use the bottom black bar for subtitle display. Cut off unimportant left, right wings.
Crop mode 2 (Recommended) Cut off top and botton black bars. (Please set subtitle to "None"). Cut off unimportant left, right wings.
Crop mode 3 Cut off unimportant left, right wings.
Crop mode 4 Cut off the top black bar, use the bottom black bar for subtitle display.
Crop mode 5 Cut off top and bottom black bar. (Please set subtitle to "None")
Crop mode 6 No cut off. (Default Mode)

Resolution:

Once your crop mode is decided, you can choose a resolution from the list. Larger resolutions require more space in your memory card. For example, 416x240 (100kpixel) usually requires twice the space as 272x160 (44kpixel) requires under the same movie quality.

Aspect Ratio:

For widescreen(16:9) movies, you can stretch the video up to 4:3 in order to remove black spaces shown on top and buttom of the screen. It's a personal preference on how much you want to stretch. Stretching too much will cause people looks tall and thin on the screen. This setting can be used together with the cropping options.

Movie Quality & Size

To reduce the output size, you can either choose a lower movie quaility or a smaller resolution. Movie quality only degrade where there is fast motion. For cartoon movies or movies without many scenes of violence, a lower movie quality still provides very good quality.

Video Frame Rate:

Known as Frame Per Second (FPS) refers to the number of pictures displayed in 1 second in order to form continuous motions. The default frame rate is 15 fps. You may choose higher fps and increase the output size to get more continous motions.

The maximum fps for NTSC films is 24fps. Countries using NTSC standard include: USA, Canada, Japan, South Korea, ...

The maximum fps for PALfilms is 25fps. Countries using NTSC standard include most European countries, Australia, China, Israel, ...

2-pass encoding

This setting allows the recorder to analyze the video stream (in the 1st pass) before recording. Based on the analysis data, the 2nd pass will generate video in better quality (especially in fast motion scenes). This is done by distributing more bits to the fast motion part (analyzed during the 1st pass) and giving less bits to the more static part.

The analysis pass is a little faster than the real recording pass. So the overall recording time of 2-pass recording is less than (single pass recording time * 2).
