Step-by-Step Capturing Procedures (with examples)

Utilizing the Camera and the capturing software



  After installation of the capture card, you may use the software that is included with the card. In this hands-on presentation two different software packages will be explained. A common software package that is shipped with most DV capture cards  is the Ulead Video Studio.  The other software is packaged with the Studio DV capture card manufactured by Pinnacle.  It is named Studio DV Software.  The Ulead software is compatible with most DV capture cards. The Studio DV software will work only on the Pinnacle Studio DV capture card.

  When you start the Ulead program you will see the following image:



  This capture screen will allow you to control the JVC9800 camera. After setting the camera to the correct video clip, you can capture the video directly to your folder on the hard disk. Make sure you set the capture folder to some partition with enough memory since the digital video file is going to be large in its native format. Latter on you can compress and trim the clip to be much smaller.

  The following video file illustrates step by step the capturing procedures:

  As you see, there are 4 images for each field. This is the unique way the JVC9800 achieves 240 Hz   You will need the APAS software latter to separate these fields to allow 240 frames per second.

  After capturing the clip which is longer than necessary, it is the time to trim the clip.

    This interface allow you to trim and edit the video clip. You will see 4 images on each field. And this how it will stay until you will use the APAS trim module which will allow the separation to 240 Hz video sequence of single fields.

  When you use the preferred Studio DV capture card, you will see the following image:

  This interface will allow you, as well, to control the video camera and then edit the clip and trim it.

The following video demonstrate step by step this procedure:

  The previous procedure created a video  clips which you can download from the following link.  This file is relatively large about 7MB. But check the quality. Welcome to digital video !

A. Clip 1 (7MB)

  This clip is the native Video. It can be compressed to produce much smaller size. However, the resolution will be effected slightly.  We will use this clip latter on to trim it at 240 Hz mode.

  The following 4 images illustrates the procedures in succession:


         1.  Capturing                               2.  Editing


        3.  Trimming                                 4. Compressing to AVI file

  First you capture the sequence. Then you edit the desire length of the sequence. You always start with longer sequence not to loose any part that you are interested in. Then you trim it to the desire sequence.  You do not need to be concern here for high accuracy since the APAS trim module will allow you to trim more accurately and synchronize the sequences. Then you can compress the data if you wish. You can also use the native DV which give you the highest resolution.  We will work with both of them in this tutorial.

  What is very interesting to this point is that you did not need the APAS system at all. Unlike other companies that tied you up to their hardware and software, so far you are free. You are using all off the shelves hardware and software. This save you alone, at least $50,000. Also, if anything is going wrong or break, it is easy to replace in the local store or on the Internet. You do not have to call us at all. However, you are always welcome to call us anytime 24 hours a day.

    Now that you capture and trimmed your video clip at 60, 120 or 240 Hz. you can use these clips with the APAS system.

We are using in our example the 240 Hz mode since any other mode is only a subset of this one.

  The first module to use is the APAS Trim module, to be able to precisely synchronize the sequences and trim them exactly to the points of interest. 

  In the next page we discuss and review the APAS Trim Module.
