Free online OGV to MTS converter

A video editor, camera workflow, or playback device may require an MPEG transport stream instead of an OGV file. Converting creates an MTS file suitable for AVCHD-oriented software and hardware, but the video and audio codecs must also be compatible.

What the OGV format is

OGV is an Ogg container commonly used for web video, open-source projects, screen recordings, and applications built around the Xiph multimedia formats. Most OGV files contain Theora video and Vorbis audio. Firefox and VLC can play them, and tools such as FFmpeg, VLC, and older desktop video applications can create or export them.

OGV is less common in consumer camcorders, Blu-ray-related workflows, and editing systems expecting MPEG transport streams, which is why it may need conversion before import or device playback.

What the MTS format is

MTS is an MPEG-2 Transport Stream container most strongly associated with AVCHD camcorders. Typical MTS files contain H.264/AVC video and AC-3 or, in some workflows, other supported audio formats. The container supports timestamped streams and is designed for recording, broadcast-style transport, and camera media rather than general-purpose web distribution.

Choose MTS when a camcorder utility, television, disc-authoring program, or editor specifically expects an AVCHD-compatible transport stream. Changing the filename extension alone does not convert OGV; the streams must be remuxed or transcoded into formats the target application accepts.

How to convert OGV to MTS

Using FFmpeg

FFmpeg is the most controllable desktop method. Open a terminal in the folder containing the source file and run:

ffmpeg -i input.ogv -c:v libx264 -preset medium -crf 18 -pix_fmt yuv420p -c:a ac3 -b:a 192k -f mpegts output.mts

This decodes the usual Theora/Vorbis streams and re-encodes them as H.264 video and AC-3 audio inside an MPEG-2 transport stream. Replace input.ogv and output.mts with the actual filenames. A lower CRF value increases quality and file size; values around 18–23 are common for H.264.

For a quick conversion where the target software accepts AAC audio, use:

ffmpeg -i input.ogv -c:v libx264 -crf 20 -pix_fmt yuv420p -c:a aac -b:a 192k -f mpegts output.mts

To inspect the source before converting, run ffprobe input.ogv. Check the frame rate, dimensions, duration, audio channels, and whether the file has multiple streams.

Using a desktop graphical converter

In a converter that exposes FFmpeg-style settings, add input.ogv, choose an MPEG transport stream or MTS output profile, select H.264 for video and AC-3 for audio when AVCHD compatibility is required, then set the destination filename to output.mts. VLC can export through Media → Convert/Save, but its available MTS profiles and codec controls vary by operating system and installation.

Converting without installing software

You can convert the file for free on the 101convert.com website when installing a desktop encoder is not practical. Upload the OGV file, select MTS as the output, start the conversion, and download the resulting file.

Quality, compatibility, and limitations

Because OGV normally uses Theora while MTS workflows normally use H.264, this is usually a transcoding operation rather than a lossless container change. Re-encoding can reduce detail and always takes longer than remuxing. Use the original OGV as the archival source.

An MTS extension does not guarantee compliance with a particular camera or AVCHD profile. Some devices require specific H.264 levels, frame rates, resolutions, bitrates, GOP structures, audio formats, or folder metadata in addition to the MTS container. If a device rejects the result, match its documented recording settings and use AC-3 audio rather than AAC where required.

Transport streams may contain brief timestamp or playback differences across applications. Test the converted file in the exact editor, player, or device that will use it, and retain the source if the conversion is for long-term storage.
