How do I convert MP4 to OGV using LetsConvert?

Upload your MP4 file to LetsConvert, choose OGV as the output format, adjust the video bitrate if you want to control file size, then click 'Convert'. After processing, download the OGV file. The tool re-encodes H.264/AAC to Theora/Vorbis automatically.

Why convert from MP4 to OGV?

MP4 uses proprietary H.264 and AAC codecs, while OGV uses open Theora and Vorbis. Converting is essential for browsers and devices that lack H.264 support, especially older Firefox and Opera versions. OGV is also preferred in open-source projects because it's royalty-free. However, OGV files are generally larger than MP4 for similar quality, so only convert when compatibility demands it.

What happens to video and audio quality when converting MP4 to OGV?

The conversion re-encodes both streams, so there's a generational loss. Resolution, frame rate, and aspect ratio are preserved. Alpha channels (transparency) are dropped because Theora doesn't support them, and color is converted to YUV 4:2:0. Audio is re-encoded to Vorbis with adjustable bitrate; the default matches the original bitrate, which keeps perceived quality but increases file size due to Theora's lower compression efficiency.
