Free online TOD to DAT converter

Devices and authoring programs that support Video CD may require an MPEG-1 video stream with a .DAT extension instead of a JVC camcorder’s .TOD file. Converting also makes the recording easier to open in older media players or import into VCD-authoring software.

What the TOD format is

.TOD is a video container used mainly by high-definition JVC Everio camcorders. The file normally contains MPEG-2 video and compressed audio in a transport-stream-style layout; the camcorder may store related recording metadata in a separate .MOI file.

TOD files are commonly copied from the camcorder’s storage card or hard disk and may not open correctly in software that expects standard MPEG program streams. The extension identifies the recording layout, not a special codec that must be preserved during conversion.

What the DAT format is

For video conversion, .DAT usually means the MPEG-1 system stream stored in the MPEGAV directory of a Video CD, commonly under a name such as AVSEQ01.DAT. It combines MPEG-1 video and audio in a format intended for VCD players and older playback software.

VCD-compatible DAT files use fixed technical constraints: typically 352×288 pixels at 25 fps for PAL or 352×240 pixels at 29.97 fps for NTSC, MPEG-1 Layer II audio, and a video bitrate near 1,150 kb/s. A file renamed to .DAT is not necessarily a valid VCD stream; the encoded structure and bitrate must also match the target software or disc standard.

How to actually convert TOD to DAT

The built-in converter on 101convert.com can process the file without installing software:

1. Open the Video conversion tool on 101convert.com.
2. Choose the .TOD file from the camcorder or computer.
3. Select DAT as the output format.
4. Start the conversion and save the resulting file after processing finishes.
5. Test the output in the intended VCD authoring program or media player before deleting the original.

For local conversion, FFmpeg can decode most JVC TOD recordings and create a VCD-compatible MPEG-1 stream:

ffmpeg -i input.TOD -target vcd output.mpg

If the receiving application only checks the extension, rename the resulting file to AVSEQ01.DAT. Do not rely on renaming alone when creating a Video CD: use VCD-authoring software to generate the disc structure and place the encoded stream in the correct MPEGAV directory. The exact authoring workflow depends on the disc-burning program.

If the TOD file contains an unsupported audio or video variant, first create an intermediate standard MPEG file with FFmpeg, VLC, or the JVC playback software, then encode that file with the VCD target. Preserve the original extension and use a new output filename so the source remains available for another encoding attempt.

Quality and compatibility limits

Converting a high-definition MPEG-2 TOD recording to VCD DAT normally reduces both resolution and bitrate. The output cannot retain the original detail, and re-encoding may introduce blocking or motion artifacts. Choose a non-VCD MPEG output instead if the destination accepts MPEG-2 or modern formats.

DAT files made for VCD are not interchangeable with every application that uses the .DAT extension. A player may accept an MPEG-1 program stream with a different filename, while strict VCD software may require PAL or NTSC dimensions, the correct frame rate, compliant audio, and a complete disc layout.

Check the source recording’s television standard before encoding. PAL and NTSC settings should not be mixed; using the wrong standard can cause incorrect frame timing, playback problems, or rejection by VCD-authoring software.
