When I test my DVD using PowerDVD which was provided with RocketDVD Pro, the DVD video is jerky.
|
|
Solution:
|
If playing the DVD using PowerDVD while RocketDVD Pro is running and previewing video capture, shut down RocketDVD Pro, then try playing your DVD with PowerDVD again.

Issue:

When I play my DVD, the video is jerky as if some frames are missing. Or when I capture video, the software encoder lags capture. This issue only relates to direct DV capture and capture from encoder boards without MPEG encoderer hardware.

Solution:
|
Re-run the video calibration wizard by right clicking on the application logo and selecting the calibration wizard. Step through the wizard and make sure that the video feed has significant motion in it. If you hook up a video camera that's pointing to the corner of a room with no motion, the video encoder will work faster than it would if there was some actual motion in the video. This will cause the calibration to set the encoder quality too high resulting in the encoder not being able to keep up encoding the video in realtime.

When I try to start a capture, I get a message saying I'm out of disc space.

Everytime you capture video to create a DVD, temporary files are stored on you hard drive. These files are stored in the directories specified for 'Work Directories for DVD Authoring:' and 'Work Directory for Captured Streams:' These files are not automatically deleted because as long as these work files exist, (if you use unique project ID's), you can reload a project and re-author, re-print or re-write the DVD. If you know you will no longer need to re-author the DVD, you can just delete the directory for captured streams, and still reproduce the job since the image and bitmaps are in the DVD authoring work directory. If you want to selectively delete work directories, they are stored in subdirectories with the project ID's name.

I selected the DV video source and I know my computer has detected the camera or DV deck, why don't I see the video preview?
|
|
Solution:
|
Click on the "more..." button on the setup display tab. On the project property page, make sure the 'Input Options' is 'Use Video Capture and Realtime Encoding'. If the 'Use Pre-Captured Files' option is set, live video is not used and hence is not shown.

When I play my DVD on a DVD player and view it on a TV, my menus are very jittery, but they look fine on the computer monitor.
|
|
Solution:
|
The computer monitor is a progressive display but a TV monitor is usually an interlaced display. This means that alternate odd/even lines are displayed at once but both are not displayed at the same time. As a result, if you have fine graphics on your menu background, sometimes the top or edge of a detailed feature including small text may appear to be shifting up and down with the alternating display of odd/even lines. This effect can be minimized by using less detail with more blending and blurring. Larger text is less susceptible to the jittery effect caused by interlaced video. To reduce the jittery effect on detail, an option is available to perform anti-aliasing over all menu backgrounds. The effect is that the menu background appears softer and possibly more blurred, but the effect will be better on most TV monitors and the softness will tyipically not be noticeable. If making DVD's primarily for progressive displays, it may be more desireable to leave the anti-aliasing off. See the preferences for this option.

When I try to use the encode feature to transode a video file for the purpose of creating a DVD, RocketDVD Pro stop or hangs at the start or in the middle and never finishes.

Solution:

First we must warn that there may not be a solution to this problem. Because the variations in video files is virtually endless, it is impossible to test every possible input. Currently, we are not using filters which would do any video frame resizing, so only D1 (720x480 NTSC or 720x576 PAL) size video is currently supported. The method used to transcode the pre-captured file is to use Microsoft's DirectShow auto connect capability. First the input file is loaded and an attempt is made to see what kind of video is present. If the file contains MPEG-2 video in the apporpriate size, it will actually be used as is without transcoding. If transcoding is needed to change the bitrate, that will have to be done with other software for now. If the video needs to be transcoded, an attempt is made to connect the video pin of the source filter to the input pin of the video encoder. If this fails, the operation should end with an error message. If it succeeds, an attempt is made to connect the audio pin to the input pin of the audio encoder. If this fails, the operation should end with an error message. If either of these steps fails, it may be due to the lack of a suitable parser or decoder for the input file format. Microsoft Windows does not come with a suitable demuxer or decoder for current versions of Apple's quicktime file format. These are not included with RocketDVD Professional but may be available from third party vendors. After reading all of this, if you still have questions, you may contact your customer support representative.

I bought the upgrade for the manual chapter feature (![]() |
|
Solution:
|
Manual chapter insertion is only available when the custom chaptering is selected on the authoring property page. When that option is selected, the button will become visible.
