  7. The following extensions must be in the Extensions folder:
    VideoSpigot Extension (if using VideoSpigot card)

Capturing still images with the VideoSpigot

  1. Set up the video camera on a tripod or other stable mounting and arrange auxiliary lighting as necessary to get a good picture on the video camera.

  2. Connect the video output of the camera to the RCA socket on the VideoSpigot card.

  3. Launch the ScreenPlay program. Turn on the video camera. You should see a picture on the ScreenPlay window.

  4. Select Preferences... in the Spigot menu. Select the image size to either Current window size (to make small pictures) or Half Size (to make large pictures) and click on Capture from still source.

  5. Focus and compose the picture. When you get the picture you want, click and hold the mouse pointer on the ScreenPlay window (the mouse pointer turns into a hand) and drag the mouse to some other area of the screen and release the button. The captured still image will appear in its own window. If you want to save the image, select Save from the File menu (or press [[apple]] -s), type a file name and press the RETURN key. Then close the image window by clicking in the small square box in the upper left corner of the image window. If you don't like the image, close the image window without saving and click on No when it says "Save ... before closing?"
  6. Repeat step 5 for all the pictures.

Capturing still images with a Macintosh AV

  1. Connect the video output of the camera to the video input socket on the back of the computer.

  2. Launch the Video Monitor program. Turn on the video camera. You should see a picture on the Video Monitor window.

  3. Pull down the File menu and select Preferences. Click on File and make sure "Compress copied frame" is not checked.

  4. Pull down the Monitor menu and select the image size to either Quarter size (to make small pictures) or Half Size (to make large pictures).

  5. Focus and compose the picture. When you get the picture you want, pull down the Edit menu and select Copy (or press [[apple]] -c). The captured still image will appear in on the computer desktop (gray screen area) as an icon. You won't be able to see the picture you captured quite yet; don't worry - go ahead and take some more pictures; you will get to see them afterwards).

  6. Repeat step 5 for all the pictures.

Compressing the images

It's not absolutely necessary that you compress your images; however, compression drastically reduces the file size of the images without significant reduction in image quality, making them easier to fit onto your available storage media.
    A. Using PICTCompressor

    1. Quit ScreenPlay or Video Monitor and launch PICTCompressor.

    2. Select Open from the File menu. Double click on the name of the file you want to compress.

    3. Select Compression... from the Image menu (or press [[apple]] -k). Set the Compressor to Photo-JPEG, Quality Normal, then click on OK. (Setting the Quality to Low will save disk space, but reduces image quality).

    4. The compressed image is shown in a separate window. The file sizes in KBytes are shown at the top right of each window. If you are satisfied, click on the compressed image to its window topmost and select Save from the File menu (or press [[apple]] -s). Delete "Compressed" from the file name, click on Save, and click Replace when its asks "Replace existing...?"

    5. Repeat steps 2 - 4 for each image.

    6. Quit PICTCompressor.

    B. Using Batch Compressor

    1. Open the folder containing all the images files that you want to compress.

    2. Drag all of the image files and drop them onto the icon for Batch Compressor.

    3. Set the Compression to Photo-JPEG, Quality Normal, then click on OK.

    4. Repeat steps 2 - 3 if you didn't get all of them the first time. The compressed files will have a .PICT extension.

    5. Quit Batch Compressor.

    C. Using Graphic Converter

    1. Either (a) drag the icon of the picture and drop it off on top of the icon of Graphic Converter, or (b) launch (double-click on the icon of) Graphic Converter, then select Open from the File menu, navigate to the desired file, and double-click on the file name.

    2. Select Picture --> Compression settings --> Still Image.

    3. From the Compressor pop-up menus, select Photo-JPEG and Best Depth, then set the Quality to Medium or High, then click on OK.

    4. Select File --> Save As... , select PICT from the Format pop-up menu and Quicktime from the Compression menu, navigate to another directory if desired, then click Save.

Putting the images into a stack

  1. Select (click once on) one of the Small picture templates or the Large picture templates and select Duplicate from the File menu. This creates another copy of that template. Rename this copy with an appropriate name and put the template and all of the image files into the same folder.

  2. Open the newly duplicated template (double-click on its icon).

  3. Pull down the Go menu and select Last. This takes you to the last card in the stack.

  4. Click in the topmost of the two rectangular fields just below the picture frame and type in the exact file name of the picture that you want on that card.

  5. Select New card from the Edit menu and repeat steps 4 and 5 for all the images.

  6. Go back through the stack and insure that each picture is displayed properly.

Putting text into your stack

  1. Each card in your stack has a large text field into which you can put text that describes or poses a question about the subject of the picture on that card. You may type directly into these fields, but may can also prepare the text separately, in your favorite word processor for example, were editing will be more familiar and where you will have access to a spell checker, etc.

  2. Transferring text from a word processor into the card fields will be most convenient if you are using System 7 and have enough memory to allow your stack and the word processor to be open on the screen at the same time. That way you can open the word processor document, select (drag over) the desired text, choose Copy from the Edit menu (or press [[apple]] -c), click on the stack window,go to the proper card, click at the top of the field, and choose Paste from the Edit menu (or press [[apple]] -v). (Once the text is pasted into the field, you can edit it and change the font, size and style just as in a word processor, by using the Font and Style menus). Repeat for each card.

  3. If you are using System 6 or if you don't have enough memory to allow your stack and the word processor to be open on the screen at the same time, you can use the Scrapbook to make things easier. Open the word processor document, then select Scrapbook from the [[apple]] menu (top left of screen). Now select the desired text from the document, Copy it (press [[apple]] -c), then click in the Scrapbook window and Paste (press [[apple]] -v). Do this for all the text sections. Then Quit the word processor, open the stack, select Scrapbook from the [[apple]] menu, turn to the proper page of the Scrapbook, Copy (press [[apple]] -c), then click on the stack window, go the the corresponding card, click in the field, and Paste (press [[apple]] -v). Repeat for all cards.

Adding Pop-up Pictures

Enhancing the Title Card

Adding sound to the stack

If you have a Macintosh model that comes with a microphone, you can easily record sounds and add them to any card in the stack. For example, you can record a spoken narration, using the small microphone that comes with the computer, or you can record music or voice from a tape recorder or CD player.
  1. Make sure you have HyperCard (or HyperCard Player) 2.1 with the Audio Help stack in the same folder as HyperCard itself. You may have to allocate more memory to HyperCard to record sounds: in the Finder, select the HyperCard icon, select Get Info from the File menu, and type 2000 into the Current size box. To check that everything is set, launch HyperCard and pull down the Edit menu: the last two items should be Audio... and Audio Help.

  2. Plug the microphone into the back of the computer, in the small round jack that is labeled with a picture of a microphone. If you are recording from a tape recorder or CD player, connect its output into the microphone input. (You will need to obtain a suitable connector cable, which you can get from Radio Shack).

  3. Select Audio... from the Edit menu. The audio palette appears:

  4. Click on the Edit button in the upper right corner of the audio palette. The audio palette expands to reveal additional controls. Set the Compression to 3 to 1 if you are recoding voice or none if you are recording music and set the Rec. Quality to Best.

  5. Go to the card where you want the sound to be played. When you are ready to record, click on the red Record button to start recording and click on the square Stop button to stop recording. Click on the Play button to check what you have recorded. If you are not satisfied with the sound, record it again.

  6. If you are satisfied with the recorded sound, type a name for the sound into the field at the top of the audio palette, replacing the name already there. (Each sound in a stack must be given a unique name.) Click on the Save button. A button will appear on the current card. Hold down the option key and drag the button to the desired location.

  7. If you want to change name or shape of the sound button, select the button tool from the Tools menu and double-click on the sound button. (This does not work in Hypercard Player; you must be using real Hypercard to change buttons). In the following dialog box you can change the button name and style or add an icon to the button. Click on OK to continue. When you are finished editing buttons, select the hand tool from the Tools menu.

  8. Repeat steps 5 - 8 for each sound you want to record. Remember that each sound in a stack must have a unique name.
