DVD to OGM: Convert Video from DVD(Digital Versatile Disk) to OGM(OGG Media) with River Past Video Cleaner, DVD2OGM converter, conversion

What is DVD?

DVD (also known as "Digital Versatile Disc" or "Digital Video Disc") is a popular optical disc storage media format. Its main uses are video and data storage. Most DVDs are of the same dimensions as compact discs (CDs) but store more than six times as much data.

DVD-Video discs respectively refer to properly formatted and structured video content. It uses MPEG-2 for video compression, with AC-3, DTS or MPEG audio for multi-channel audio support.

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

What is OGM?

Ogg Media (OGM), meaning Ogg Media File, is a container format (for video, audio and subtitle streams). It was developed by Tobias Waldvogel and can do a few things the common AVI format cannot.

OGG Media is a video file format with OGG container. It is not as popular as Matroska.

To encode OGG media file with River Past software, please have either Torbias' OGG DirectShow Filters or Radlight Ogg Media Filters installed.You may also need CCCP.

Open DVD

Click on the "Add DVD" button on the tool bar. The standard directory open dialog appears. Select your DVD drive or select the "VIDEO_TS" directory.

Select the drive and click "OK". Video Cleaner will parse the directory and add all the video chapters on the disc.

Handling of encrypted DVD's

Most commercial DVD's are copy protected. Our software cannot convert from encrypted DVD's. You can use a third party software to rip the DVD to hard drive first, then browse to the VIDEO_TS directory in our software.

Difference between "Add DVD" and "Add Files"

Do not use "Add Files" to select the VOB files on the DVD disc. 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 example, VTS_01_1.VOB contains a still menu, chapter 2, and then the beginning of chapter 3. VTS_01_2.VOB contains the end of chapter 3, and beginning of chapter 4. VTS_01_3.VOB contains the middle of chapter 4. VTS_01_4.VOB contains the end of chapter 4 and beginning of chapter 5, and VTS_01_5.VOB contains the end of chapter 5.

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.

That's why you should 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.

If you encounter an error when adding the DVD, please make sure you have GPL MPEG-2 Decoder filter and AC-3 Decoder filter installed.

Select output format

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Output Format" label to expand the panel. Select "OGM - OGG Media" as the "File Type".

Note: To convert to OGM files, you must have OGG Vorbis DirectShow filters installed.

Change Video Settings

Click on the toggle to the left of the "Video Settings" label to expand the panel.

Select "Specify" under "Size" and/or "Frame rate" to enter the video resolution and/or frame rate.

You can change the compressor, quality, size, and frame rate of the video.

Change Audio Settings

Click on the toggle to the left of the "Audio Settings" label to expand the panel.

Select the audio compressor for the conversion. Depending on the compressor, you may also change the sample rate, channel (stereo or mono), bits/sample, and bitrate.

Do not use "MPEG Layer-3" as the audio compressor. It does not work correctly in video files and often causes the conversion to abort in the middle. If you prefer to have MP3 audio in the AVI file, download lame_enc.dll instead.
