OGV to XviD Converter

OGV to Xvid: What This Tutorial Covers

You have an .ogv — Ogg Theora, the open-format video the web used before H.264 became universal — and something old will not play it. That is an entirely reasonable place to be, because a Theora file has quietly stopped playing almost everywhere: Chrome disabled the decoder by default in version 120, Chromium removed it in 123, Firefox disabled it by default in 126, and Safari never shipped it at all.

Xvid takes you the other direction in time. It is an MPEG-4 Part 2 Advanced Simple Profile encoder, released in 2001 under the GNU GPL, and it is what DivX-certified DVD players, old portable media players and car head units were built to decode. This walk-through covers the conversion, the rename that catches nearly everyone, the settings that decide whether legacy hardware accepts the file, and the point where a different target is the better answer.

How to Convert OGV to Xvid

1. Upload Your OGV File: Drag the .ogv onto the page or click "Add Files" to browse. Several files can be queued and converted with the same settings.
2. Leave the Video Codec and Choose an Audio Codec: Video Codec contains a single entry, Xvid, so there is nothing to decide there. Audio Codec opens on MP3 — the classic Xvid-in-AVI pairing — with AC3, EAC3, MP2, AAC, FLAC, Vorbis, Speex, WMA v1/v2, DTS and the PCM variants (A-law, mu-law and 16/24/32-bit little-endian) also listed.
3. Set File Compression, Video resolution and Trim (Optional): File Compression opens on Quality Preset at Very High (Recommended), with Specific file size, Constant Bitrate, Variable Bitrate, Constant Quality and Constraint Quality alongside. Video resolution opens on Keep original; Preset Resolutions, Width, Height and Width x Height are the alternatives. Trim offers Unchanged or a Time Range with a Start time and Duration.
4. Convert and Download: Click Convert and take the file. It uploads over an encrypted connection, is re-encoded on our servers, and is deleted automatically after a few hours. No sign-up, no watermark.

Walk-through: Rename the Download Before You Do Anything Else

Xvid is a codec, not a container. There is no such thing as an "Xvid file format", so .xvid is not a real container extension — the file you download is an AVI file carrying a .xvid name. Inside it is an MPEG-4 Part 2 video stream tagged with the FourCC xvid, which is precisely what DivX-certified hardware scans for, alongside the audio codec you selected. A file produced this way probes as format avi, video stream mpeg4, codec tag xvid.

So the first step after downloading is not an encoding decision at all:

• Rename clip.xvid to clip.avi. Nothing is re-encoded and nothing inside the file changes; you are correcting a label.
• Content-sniffing players do not care. VLC and mpv identify files by inspecting their bytes and open the download under either name.
• Extension-driven players do care. Windows Media Player, DVD players, TV media browsers and car head units decide what to do from the extension alone and will simply not list a .xvid file.

Once it is named .avi, matching the hardware is what is left:

• Keep the frame standard-definition. Many SD-era certified players reject anything above 720 x 576. Use Width x Height for an exact 720 x 480 (NTSC) or 720 x 576 (PAL) frame, or Preset Resolutions at 480p or 576p if you want the width derived from your source's aspect ratio.
• Stay on MP3, or move to AC3. Both decode on DivX-certified hardware. AAC generally does not, even though the dropdown offers it.
• If playback stutters, lower the bitrate rather than the resolution. Certified players are built to a profile ceiling; switching File Compression to Constant Bitrate and setting a modest rate is the direct fix.
• Burn a data disc, not a Video DVD. Copy the .avi onto a data DVD-R or a USB stick and open it from the player's own file browser.

One geometry caveat that only bites large sources: the Xvid encoder here is capped at 2048 pixels on each axis, and at Keep original that cap is applied per axis with no aspect correction — a 3840 x 2160 source lands at 2048 x 2048 and is squashed. Ogg Theora files are rarely anywhere near that size, but if yours is, choose a Preset Resolution instead, which sets the height and lets the width follow the source shape.

Theora and Xvid at a Glance

Quality Controls, and Which Ones Really Move the Output

Xvid is not a CRF codec, so the rate-control group behaves differently from what an H.264 page would lead you to expect:

The one to be careful with is Constant Quality. The numeric box is labelled "CRF" because the control is shared with H.264-class codecs, but on Xvid the number lands on the MPEG-4 quantiser scale of 1 to 31, where 1 is near-lossless and 31 is very coarse. It genuinely works — it is just labelled for a different codec family. If you are not deliberately setting a quantiser, stay on Quality Preset or Constant Bitrate.

Common Errors and How to Fix Them

• "My player does not even list the file." The extension. Rename .xvid to .avi before changing any setting.
• "The output is bigger than the OGV." Expected. Theora and Xvid are both older than H.264, but they are not equivalent, and a re-encode at a generous preset will usually spend more bits than a low-bitrate web Theora file did. Lower the preset or set a Specific file size.
• "The picture is stretched or squashed." Either a 16:9 source was forced into a 4:3 frame with Width x Height, or a very large source hit the 2048-pixel encoder cap at Keep original. Set the frame explicitly to the shape you want.
• "The player shows the file but refuses to start it." Usually resolution or bitrate. Re-encode at 720 x 576 or lower with Constant Bitrate at a modest rate.
• "There is no sound on the old player." You probably picked AAC. Most DivX-certified hardware decodes MP3 and AC3 only.
• "Interlacing combs are still there." This conversion does not deinterlace, so an interlaced source stays interlaced. Deinterlace before uploading if that matters.

When This Doesn't Work

If the device you are feeding was made in roughly the last decade — a phone, a tablet, a smart TV, a computer or anything with a browser — Xvid is the wrong target and only inflates the file. Convert to OGV to MP4 instead; H.264 in MP4 plays essentially everywhere and is far more efficient. If your hardware's manual names DivX specifically, OGV to DivX writes the same family of stream under that name, and OGV to AVI gives you a plainly named AVI with no renaming step at all. And if the .ogv itself is truncated or corrupt — a real risk with files salvaged from dead 2010-era websites — no re-encoder can repair it; you need a clean copy of the source.

Frequently Asked Questions

Why is the download called .xvid instead of .avi?

Because Xvid names a codec rather than a container, and the page names the output after the codec you asked for. The bytes inside are a standard AVI file holding an MPEG-4 Part 2 video stream with the xvid FourCC and your chosen audio track. Rename it to .avi and every AVI reader opens it — nothing is re-encoded by renaming and no quality changes. Players that sniff file contents, such as VLC, play it under either name.

Will converting Theora to Xvid improve the picture?

No. This is a lossy-to-lossy re-encode into a codec of a similar generation, so the honest outcome is "the same picture or slightly worse, in a format old hardware can read". Ogg Theora files from the web era were frequently encoded at low bitrates, and nothing in an Xvid encoder can rebuild detail Theora already discarded. Raising the preset only stops the second encode adding more damage.

Is Xvid the same thing as DivX?

They implement the same standard — MPEG-4 Part 2 Advanced Simple Profile — and in practice they play on the same certified hardware. The difference is origin and licence: Xvid was released in 2001 as free software under the GNU GPL v2, forked from OpenDivX after DivXNetworks closed their source. If your device's documentation names DivX explicitly, OGV to DivX writes the same family of stream under that name.

Why can I not choose a different video codec on this page?

Because the page's whole purpose is to produce an Xvid stream, so the Video Codec group has one entry. The Audio Codec list is where the real choice is, and it is long — MP3 by default, plus AC3, EAC3, MP2, AAC, FLAC, Vorbis, Speex, WMA v1 and v2, DTS and the PCM variants. If you want a different video codec in an AVI wrapper, OGV to AVI exposes the AVI codec list instead.

My .ogv will not play in Chrome or Firefox — is the file broken?

Almost certainly not. Browsers removed Theora: Chrome disabled it by default in version 120 and Chromium deleted the decoder in 123, Firefox disabled it by default in 126, and Safari never had it. The file is still perfectly valid, which is why VLC, mpv and any ffmpeg-based tool open it without complaint — and why this converter can read it. If you want something that plays in a browser again, OGV to MP4 or OGV to WebM is the target, not Xvid.

What resolution should I use for an old DVD player?

Match the region's standard-definition frame: Width x Height at 720 x 480 for NTSC or 720 x 576 for PAL. If you would rather set only the height and keep the source's aspect ratio, Preset Resolutions offers 480p and 576p and derives the width. Going above 720 x 576 is the most common reason a certified player shows a file in its browser but refuses to play it.

Can I convert only part of a long recording?

Yes. Switch Trim from Unchanged to Time Range and enter a Start time and a Duration, in seconds or as HH:MM:SS.sss. Only that window is decoded and re-encoded, which also makes it the fastest way to test a resolution and bitrate combination before committing to a full-length file. To split one source into several separate clips instead, use Video Cutter first and convert each piece here.

Does the Vorbis audio survive the conversion?

It is re-encoded, not carried across. AVI does not host Vorbis well and old hardware certainly cannot decode it, so the Vorbis track is decoded and compressed again into whatever you selected under Audio Codec — MP3 by default. There is no pass-through mode on this page; the server always re-encodes both streams.

Should I be converting to Xvid at all in 2026?

Only with a concrete reason: a DivX/Xvid-certified DVD player, an old portable media player, a car head unit, or a pipeline that mandates Xvid in AVI. For anything current, H.264 in MP4 is universal, smaller and far easier to work with — try OGV to MP4 first and fall back here only if the hardware refuses it.
