VOB to GIF: Convert Video from VOB(DVD Media File) to GIF(Animated GIF) with River Past Video Cleaner, VOB2GIF converter, conversion

What is VOB?

VOB standards for "Video Object". It is the file type to store video on a DVD disc. It is actuallly a MPEG-2 video, with special extension to support PCM, AC3, DTS audio, subpictures, and button navigation commands.

To decode DVD-VIDEO, you will need both GPL MPEG-2 Decoder, and AC-3 Decoder.

What is GIF?

Animated GIF is not really a video format. It is a sequence of GIF frames stringed together. Due to the 256-color limitation of GIF, the color is dithered. The compression is not that great, so the file size tend to be large given the frame rate and resolution.

However, since GIF is supported by all web browsers without any add-on, it is a great way to create small video thumbnails. Generally, the resolution should be kept small (80x60, for example), the frame rate should be kept low (4 fps, for example), and the duration should be kept under a few seconds.

Animated GIF is not really a video format. It uses 256-color GIF compression, with low quality and relatively large files. It is not suitable for video playback. However, since it is supported by all web browsers without any add-on's, it is a great format for video thumbnails and should be used for this purpose only.

To encode a video to an animated GIF, you need to have River Past Animated GIF Booster Pack in addition to the video software.

Add VOB File

Click on the "Add Files" button on the tool bar. The standard file open dialog appears. Select "VOB - DVD Media(*.vob)" in its "Files of type" combo box.

You should only use "Add Files" to select VOB files if they are generated by a DVD authoring software and each VOB file represent a single video clip. Do not use "Add Files" to add the VOB files on a DVD disc or DVD image.

A DVD contains many video clips, which are then divided into cells/chapters. All of the video clips are then streamed together in one big block. The VOB files on the disc is just a way to divide the block into 1GB files to be compatible with older operation systems like Windows 95, who has a file size limit.

Each VOB file on the DVD may contain multiple videos. Each video may span over multiple VOB files. If you use "Add Files", only the first clip in that particular VOB file will be parsed and added.

This picture below makes it easier to understand.

In this case, if you use "Add Files" to add VTS_01_1.VOB, you will only get the still menu. If you use "Add Files" to add VTS_01_2.VOB, you will get the end of chapter 3... This is how file based decoding works.

If you want to convert from a DVD disc or DVD VIDEO_TS directory image, use "Add DVD". We will parse the DVD information and find all the cell breaks. You will get to select which cell to convert, from 2 to 5. Still menus are ignored.

Animated GIF is NOT a video format and is not designed for video playback. It is limited to 256 colors, so the video will be dithered. GIF compression is designed for solid color graphics, so it is not very efficient for video. The resulted animated GIF files are normally much larger than the original video file, given the same resolution and frame rate.

For the above reasons, it is not a good idea to use animated GIF to share your video on the web. Instead, it is an excellent way to display a small moving thumbnail for the link to your video. For this purpose, you should specify the size to around 80 x 60, and frame rate to 2 frames per second for the best result.
