AVIF to XviD Converter

How to Convert AVIF to Xvid Online

1. Upload Your AVIF File: Drag and drop or click "+ Add Files" to load static or animated AVIF images. Batch upload is supported — drop a single hero shot, a folder of stills for a slideshow, or an animated AVIF and the converter will process them in one pass.
2. Pick Video Codec and Audio Codec: Default video codec is Xvid (open-source MPEG-4 Part 2 ASP) wrapped in an AVI container — the format DivX/Xvid-certified hardware decodes natively. Switch to MPEG-4, DivX, H.264, MJPEG, or MPEG-2 if your downstream tool needs a different profile. Audio codec defaults to AAC; pick MP3 for Windows Movie Maker, AC-3 for DVD authoring, or PCM for uncompressed editing masters.
3. Set Image Duration, Background Color, Resolution, and Quality (Optional): Choose per-frame duration from 1/60s up to 10s — pick 1/24s or 1/30s to mirror animated AVIF playback, 3-5s for a calm photo slideshow. Set Background Color (Black is the DVD-player default; 23 other named colors available) so AVIF's alpha channel flattens predictably for letterbox bars. Pick a resolution preset (720×576 PAL, 720×480 NTSC, 854×480, 1280×720, 1920×1080) or enter custom Width/Height. Tune size with a Quality Preset (Highest → Lowest), target a percentage of source size, hit an exact MB target, or fine-tune with QSCALE (1-31, lower = better).
4. Convert and Download: Click Convert. Files process in your browser session and download as a single .avi — no sign-up, no watermark, no upload to a third-party server. Drop the file on a FAT32 USB stick or burn to DVD-R for a certified player.

Why Convert AVIF to Xvid?

AVIF (AV1 Image File Format) is the newest mainstream still and animated image format, shipping in Chrome since 2020 and Safari since 2022. Xvid is an open-source MPEG-4 Part 2 (ASP) codec, bitstream-compatible with DivX-certified hardware sold between 2003 and 2015. Converting AVIF → Xvid bridges roughly two decades of compatibility: the playback target is a DVD player, car head unit, or set-top box that has never heard of AV1 but happily decodes the orange-logo "DivX" profile. For modern phones, smart TVs, and the open web, convert AVIF to MP4 instead — H.264 is roughly half the file size at the same visual quality.

• DivX/Xvid-certified DVD players (2003-2012) — Philips, Pioneer, Sony, Samsung, and Panasonic shipped DVD players with the orange "DivX" logo, covering the MPEG-4 ASP profile that Xvid implements. Burn the converted .avi to a DVD-R as data and the player reads it like any DivX disc.
• Car head units and aftermarket DVD/USB players — Pioneer AVH-series, Kenwood DDX-series, and JVC KW-series in-dash receivers from 2005-2014 are DivX-certified. An AVIF photo album becomes an Xvid slideshow that plays back from a FAT32 USB stick on the dashboard screen.
• Animated AVIF unrolling for legacy editors — A short animated AVIF (product hero, banner ad, sticker) becomes a frame-accurate AVI you can scrub in VirtualDub, Pinnacle Studio, or Windows Movie Maker — none of which recognize AVIF as an input format.
• Industrial signage and embedded displays — Older Scala, Onelan, and BrightSign Classic players, factory HMI panels, and waiting-room signage from 2010-2018 only loop AVI/MPG content. AVIF plays nowhere in that ecosystem.
• Portable DivX/Xvid players and PMPs — Archos, Cowon, and iRiver portable media players from before the iPad era decode MPEG-4 ASP in hardware. Converted Xvid files extend the useful life of these collectible devices.
• Legacy media-library consistency — Adding new content to an existing Xvid .avi library (Windows XP-era home theater PCs, MPC-HC playlists) keeps a single decoder profile across every file in the folder.

If you don't specifically need the Xvid profile, AVIF to MP4 gives much smaller files with H.264, AVIF to GIF preserves animation for chat apps, and AVIF to WebM is best for modern browser embeds.

Codec and Image-Duration Quick Guide

Frequently Asked Questions

Should the file extension be .xvid or .avi?

Use .avi. Xvid is a codec, not a container — the bitstream is wrapped in AVI for delivery. Almost every DivX/Xvid-certified player scans only for .avi (some firmware refuses anything else), and Windows, VLC, and MPC-HC all map .avi to the right decoder automatically.

Why pick Xvid over MP4 in 2026?

DivX/Xvid-certified DVD players, set-top boxes, and car DVD systems made between 2003 and 2015 have an MPEG-4 ASP decoder chip and reject H.264. If the playback target is a Pioneer AVH head unit, an early Samsung TV with USB, or a basement Philips DVD player, Xvid is the only codec the hardware understands. For phones, modern TVs, and the open web, AVIF to MP4 is roughly half the file size at the same visual quality.

What happens to AVIF transparency in the Xvid output?

MPEG-4 ASP has no alpha channel, so AVIF's 10-bit or 12-bit alpha is flattened to the background color you pick in step 3. Default is Black, which matches DVD-player letterbox bars. Pick White for a clean look, or one of the 23 named colors to match a brand or stage backdrop. If you need precise alpha compositing first, convert AVIF to PNG and edit there.

Will animated AVIF frames transfer to Xvid correctly?

Yes. Each frame of the animated AVIF becomes a frame of the AVI. To match the original animation speed, set the per-frame Duration to 1/24s, 1/30s, or 1/60s. Static AVIF files become a single still frame extended to whatever duration you pick (typically 3-5 seconds for slideshows).

Should I pick Xvid or DivX for a certified player?

DivX-certified hardware decodes both — the certification covers the MPEG-4 ASP profile that Xvid and DivX share. Pick Xvid for new conversions where you want an open-source encoder. If you are matching an existing DivX library and want consistent profile flags, switch the video codec to DivX in step 2. For pre-2004 certified devices, drop down to plain MPEG-4 (Part 2 baseline).

What resolution should I pick for an old DVD player or car head unit?

Stay inside the device's DivX profile. Most 2003-2008 certified DVD players cap at 720×576 (PAL) or 720×480 (NTSC) — pick the matching preset. 2008-2012 certified TVs and head units handle up to 1280×720. DivX Plus HD certified TVs (2010+) handle 1920×1080. Going above the profile produces a file the player rejects or stutters on.

Why is my Xvid AVI larger than the source AVIF?

This is normal. AVIF uses AV1 still-image compression — one of the most space-efficient image formats ever shipped (typically 50% smaller than JPEG at the same quality). MPEG-4 ASP is a 2001-era codec without modern entropy coding, and AVI adds per-frame container overhead. Expect a 5-20× size increase, especially with long per-frame durations. If file size matters more than DivX hardware compatibility, use AVIF to MP4 with H.264 instead.

How long will my Xvid video be if I upload N AVIF stills?

Output duration = number of images × image duration. 60 photos at 4 seconds each = 240 seconds (4 minutes). 1,800 timelapse frames at 1/30s = 60 seconds. The setting is per-image and applied uniformly across every AVIF you upload. Drag to reorder before clicking Convert.

Can I add a music track to the slideshow?

The converter produces a silent .avi from AVIF input — there's no audio source to encode. To score the slideshow, convert here first, then layer in music with merge it with a video editor (DaVinci Resolve, Shotcut, CapCut, Adobe Premiere). AVI supports MP3, AC-3, and PCM audio when a source track exists; the audio codec setting kicks in once one is added downstream.

Will the file fit on a single DVD-R or USB stick?

A 720×576 Xvid at 2000 kbps lands roughly 900 MB per hour of runtime — two hours fits inside a 4.7 GB DVD-R with room for a second feature. 1280×720 at 4000 kbps lands roughly 1.8 GB per hour. For a USB stick, format as FAT32 (most certified players reject exFAT and NTFS), keep filenames under 64 characters, and stick to ASCII for older firmware.
