Del DeVries : Video Clips

^{see Movie Clips}

UPDATE  July 28, 2010  

FLV Extract 1.6 - http://moitah.net/#FLVExtract - quickly extracts a usable MP3 from a FLV file (didn't test the AVI).    

http://www.virtualdub.org/ (Virtual Dub) appears to have continued development as well.

Objective - extract small video clips that can be played through Windows Media Player. Generally, this means extracting the clip from either a commercial DVD or a recorded DVD. The intended use should be designed to comply with Copyright Fair Use (for example reproduction by a teacher or student of a small part of a work to illustrate a lesson).

Tools Required:

VirtualDub-MPEG2 - Windows video software to read a .VOB content file from a DVD, preview and mark portions of the video/audio for extraction, and output an AVI video which can be played in Windows Media Player. High quality, simple, and efficient.
AVI codec - the output video file specification. Both work well, advantages and disadvantages of each are detailed at http://www.animemusicvideos.org/guides/avtech/video4_2.htm (along with numerous other codecs!). The AVI codec provides compression of the output video file. A 3 minute clip at 640x480 will range between 25 and 100MB. Uncompressed, the same clip is about 3,000 MB.
- XviD Fast, Open Source, Customizable, and Gorgeous
- DivX the codec is free, but the download included trialware and your final clip will have a DivX watermark in the lower right corner.
Resizing of the video file is possible either through the codec (XviD seems to handle this better) or through a filter in VirtualDub. The Smart Resize Filter works a little easier than the built in Resize (both must be "added" under the Video -- Filter menu, and then options set to get the correct output size). My DVD Recorder creates NTSC 4:3 DVD's directly from cable TV signals as 320x240 output. Resizing these to 640x480 creates a better presentation size.
- Depending on your purpose and the type of video - a wide range of filters for VirtualDub are available at http://neuron2.net/index.html

Resources

updated June 2008 - Microsoft Expression Encoder 2 detailed review of the updates to Microsoft Media Encoder
A&E's Technical Guides to All Things Audio and Video mk 2 - a well written and comprehensive guide to video and audio. MUCH more detailed than my simple summary above! Note that if VERY high quality audio is important to you, pay attention to this guide!
Video Help - How to convert DV to DivX or XviD using Virtualdub - rather short and sweet, but illustrated.
Movie Maker - Importing Video from Discs - well written descriptions that show the evolution of these video tools over the past few years. Includes information about importing the output clip into Microsoft's Movie Maker for additional editing.
VirtualDub - the home site for the open source project. Includes a forum.

Step by Step Process from DVD to PC Ready Video Clip

Highly summarized list follows! More details are in the resources above.

Load the software tools - primarily VirtualDub
Copy the .VOB file to your hard drive (optional - but having a single folder for input and output makes the process steps easier)
Set the options in VirtualDub for compression using XviD and select resize controls or filter.
Set the Start and Stop for the clip
Extract to AVI file
Play the short clip in WMP
