This feature is implmented using the ffdshow raw video filter. Since it is a third party add-on, it does require manual configuration. In addition to resizing, this filter can also be used for the following:
|
|
· | OSD
|
· | Cropping
|
· | Deinterlacing
|
· | Postprocessing
|
· | DeBanding
|
· | Levels
|
· | Blur & Noise Reduction
|
· | Sharpening
|
· | Resizing & Aspect Ratio
|
· | Bitmap Overlays
|
· | Subtitles
|
|
You can download the ffdshow filter from the following link: http://ffdshow-tryout.sourceforge.net/. For the actual download, choose the download link at the left end of the three links in the middle of the page.

In this help file we will only discuss the resizing and aspect ratio which are the features we wish to take advantage of. Depending on the video sources, you may or may not need to change your resize settings very much. The following configuration page can be brought up by clicking the configure button on the Capture/Encode property page or the Preferences property page. It can also be brought up outside of RocketDVD Professional through the start menu -> All Programs -> ffdshow -> video decoder configuration.

In most cases, you will want to use the Specify horizontal and vertical size in the Resize box above. Changing the Aspect Ratio in the Resize box doesn't have any effect unless Specify aspect ratio is selected. If you are transcoding PAL video, you will most likely want to set the vertical size to 576 instead of 480.

In the Aspect ratio group, if you know your video has square pixels, you can use Keep original aspect ratio. If you know that your video's aspect ratio, you can select the Manual Aspect ratio setting and pick the desired aspect ratio from the drop down list.

In general, it is important to know that there are different settings to be used with different video sources. Just play around with and be comfortable with what each of the settings do.

One more note about downsizing and authoring HD video. You may need the Haali Media Converter in order to read/demux the m2tx streams.

Feel free to experiment with the other filters to see if they are useful to you. We have tried some but not all of them.
