After visiting http://www.squared5.com/ download the (FREE) MPEG Streamclip application for your computer (choosing from either the Mac or PC link options shown in the left-hand tabs of the website. You can also download the DC30 Xact Driver for Mac G4 (driver for the DC30 video card) if needed, for use on select Mac computers to allow for audio/video input & output options with MPEG Streamclip.

*MPEG Streamclip How-To*

OPENING A DVD:

With the "Open DVD" command of the File menu, you can open a DVD by choosing the whole disk, or its VIDEO_TS folder; you can also select any VIDEO_TS folder located anywhere. You can even open a DVD by dragging it over the player window. If the DVD contains multiple movies (titles) MPEG Streamclip will ask you to choose which movie you'd like to open.
Once you’ve opened the DVD in MPEG Streamclip, you will want to open the video clip’s stream info...

READING STREAM INFO:

All relevant data are reported in this window. Showing your video’s Stream Info is important as it indicates which compression settings are best for your video upon exporting. Simply go to File and Show Stream Info, (or, alternatively, press the Command button + “I”, as a short-command).

Once you have this Stream Info window open, you may want to move the window outside of the MPEG Streamclip window, so that, when exporting your file and choosing its compression settings, you can have the stream’s Stream Info on hand to match the stream’s export/compression settings for the best video playback results.

THE IN’S AND OUT’S:

You can have your clip start and stop at specific points of the clip’s timeline by first choosing where you’d like to start the clip (clicking on a specific time on the timeline underneath the video) and then pressing the ‘I’ button on the keyboard. Then you will want to select where you’d like the video to end, upon ultimately saving/exporting your stream, by clicking on a particular time on the timeline and then pressing the ‘O’ button on the keyboard. Alternatively, you can select these times on the timeline and choose the ‘Select In’ and ‘Select Out’ commands from the Edit pull-down menu.

INTERLACED/DEINTERLACED VIDEO DOUBLE-CHECK:

Before you finally save or export your stream to another format or save the current clip with possibly revised in and out points, etc., you should first see if your video is interlaced or deinterlaced. Interlaced video is common among DVDs created from at-home DVD players among other instances. You can tell if your video is interlaced by manually scrolling through the video forwards or backwards with the ‘?’ and ‘?’ arrows on the keyboard, or, alternatively, using your mouse’s scroll button to scroll up and down the stream. Upon scrolling forwards or backwards through the video, if your video does not appear to have jarring, distinct comb-like horizontal bars overtop it, interfering with the video, the video is already de-interlaced and you needn’t deinterlace upon exporting the stream to another format. If the bars show up upon scrolling or standard playback, the video is interlaced and for should certainly be deinterlaced upon export.
To simply save the stream, with whatever edited in’s and out’s or whatever settings/preferences you’ve modified, you can do so by selecting the ‘Save As...’ option from the File pull-down window.

Otherwise, the following information should guide you on exporting your stream with customized compression settings to another video format.

EXPORTING STREAM TO OTHER FORMATS:

If you are interested in exporting your DVD in a raw, uncompressed video format, choose ‘Export to DV’ from the File menu.

You will likely want to choose DV (DV25) as your compression setting, ‘NTSC, 720 x 480, 29.97 fps’ as your Standard (unless your video was made in Europe or somewhere else in the world that’s NOT the U.S., then you would choose PAL as your standard), and your aspect ratio should be 4:3, unless your video happens to be widescreen. The deinterlacing option is available in this exporting window, if you had previously noticed the horizontal, comb-like interlace bars upon scrolling through your video/playback. You can choose to rotate/flip your video if desired or Zoom/Crop your video to make certain quick, specific edits to the video if desired.

***For faster, less size-consuming video exporting options, you can choose from one of the following exporting file formats...

Exporting to Quicktime is helpful for playback with Apple’s Quicktime video player, or, more specifically, using the exported video file with an Apple Mac computer or Apple-owned video software.
Exporting to .AVI is helpful for playback on any PCs (ex.: if you are using MPEG Streamclip on a PC to open the exported clip in, say, Windows Media Player, you may want to choose the .AVI export option for the best playback results).
Exporting to MPEG-4 is a simple alternative video format you can choose, especially if your source video file was an MPEG-2 (MPEG-4 has an improved coding efficiency to that of the MPEG-2 file).
Exporting Audio gives you the option to export ONLY the audio from your given video stream.
Exporting to Other Formats allows you to export your stream to a number of file formats (iPod and iPhone settings are desirable for your respective devices, AIFF and .WAV allow you to save your file as uncompressed, high-bitrate audio files, etc.).
Exporting Frame allows you to export whatever frame of the video you are currently on to a variety of image formats as a still frame.
