Why Convert OGV to MP4?
OGV (Ogg Video) is an open-source video format that uses the Theora video codec and Vorbis audio codec. While OGV is royalty-free and supported by Firefox and Chrome, it has limited compatibility with mobile devices, smart TVs, video editors, and social media platforms. MP4 with H.264 is the universal video format — it plays on every device, browser, and platform. Converting OGV to MP4 ensures your videos are playable on iPhones, Android phones, smart TVs, and game consoles, uploadable to YouTube, Instagram, TikTok, and other social platforms, editable in Premiere Pro, DaVinci Resolve, iMovie, and other editors, and streamable with efficient H.264 compression.

Will converting OGV to MP4 improve quality?
Converting cannot add detail that wasn't in the original, but H.264 is a more efficient codec than Theora — so you can get similar visual quality at a smaller file size. Use "Highest" Quality Preset or Constant Quality (CRF) with a low value (18-23) for the best results.
Which video codec should I choose?
H.264 (the default) is the safest choice — it plays on every device. H.265/HEVC produces ~40% smaller files but has less device support. AV1 offers the best compression but is slower to encode. For maximum compatibility, stick with H.264.
Can I trim the video during conversion?
Yes. Under Trim, select "Time Range" and enter a Start Time and Duration in seconds or HH:MM:SS.sss format. This lets you extract a specific clip without needing separate editing software.
Does OGV support transparency?
Some OGV files include an alpha channel for transparency. Standard MP4 with H.264 does not support transparency, so alpha is flattened to a solid background during conversion. If you need transparency, convert to WebM with VP9 instead.
What audio codec is used?
The default for MP4 is AAC, which is the standard audio codec for MP4 files and works on all devices. You can change this under Audio Codec to MP3, AC3, Opus, or FLAC depending on your needs.
