Free online TOD to F4V converter

What the TOD format is

TOD is a video container used mainly by JVC Everio high-definition camcorders. It normally stores MPEG-2 video in an MPEG transport-stream structure, commonly at 1440×1080 or 1920×1080, with audio such as MPEG audio or AC-3. You typically encounter .tod files after copying recordings from an Everio camcorder or its removable media; related JVC workflows may also include MOD and metadata files.

TOD is not the same as a standard MPEG-2 program-stream file, so some general-purpose players and editors fail to identify it correctly even when they support MPEG-2. FFmpeg, VLC, and several professional video applications can usually inspect or decode it.

What the F4V format is

F4V is Adobe Flash Video stored in an ISO Base Media File Format container, similar to MP4. It is intended primarily for H.264 video with AAC audio and was used for web delivery through Adobe Flash Player and related Adobe media tools.

F4V can provide smaller files than the MPEG-2 video commonly found in TOD while retaining good quality at a lower bitrate. Its practical value is now limited because Flash Player and browser Flash support ended; use F4V only when the receiving application or archive specifically requires it. For current web playback, MP4 is usually the more compatible target.

How to convert TOD to F4V

Using FFmpeg

FFmpeg is the most controllable desktop option. Install a current build, place the TOD file in an accessible folder, open a terminal in that folder, and run:

ffmpeg -i input.TOD -map 0:v:0 -map 0:a:0 -c:v libx264 -preset medium -crf 18 -pix_fmt yuv420p -c:a aac -b:a 192k -movflags +faststart -f f4v output.f4v

Replace input.TOD and output.f4v with the actual filenames. The command decodes the MPEG-2 source, encodes H.264 video and AAC audio, and writes an F4V container. A lower CRF value increases quality and file size; values around 18–23 are common starting points. Remove -map 0:a:0 and the audio options if the source has no audio.

To inspect the streams before conversion, run:

ffprobe input.TOD

If the recording is interlaced, deinterlace it during encoding with:

ffmpeg -i input.TOD -map 0:v:0 -map 0:a:0 -vf bwdif -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a aac -b:a 192k -movflags +faststart -f f4v output.f4v

Use the deinterlacing version only when ffprobe or visible horizontal combing confirms interlaced footage. Otherwise, it adds processing without improving the source.

Using the built-in online converter

You can convert the file for free on 101convert.com without installing software: upload the TOD file, select F4V as the output format, start the conversion, and download the resulting file. Uploading is less suitable for confidential footage or very large camcorder recordings because the source must leave your computer and processing depends on the service.

Quality and compatibility considerations

This conversion normally requires re-encoding because TOD's MPEG-2 video and common audio streams are not the codec combination expected in F4V. Re-encoding causes some quality loss; preserve the original TOD and avoid repeated conversions. The -crf 18 setting prioritizes quality, while -crf 21 to -crf 23 produces smaller files with more compression.

F4V does not make a file compatible with modern browsers by itself. Test the result in the exact application that requires it; if no legacy Flash workflow is involved, choose MP4 with the same H.264/AAC settings instead. Check the output duration, aspect ratio, audio synchronization, and interlacing before deleting the original recording.
