Situation. AVI is the legacy Microsoft Audio Video Interleave container from the 1990s. Solution: a WMV, produced below. Repackaging a AVI file into WMV is one of the fastest video jobs there is. When the codecs already match the target container specification, the bytes are literally copied across — no re-encoding, no quality drop, no long wait. Upload above and watch the progress bar usually fly. In practice AVI is the legacy Microsoft Audio Video Interleave container from the 1990s. On the other end, WMV is Microsoft's Windows Media Video codec and container, tied to the Windows ecosystem.
AVI Video
Source formatAVI is a legacy Microsoft multimedia container that stores audio and video data. While largely superseded by modern formats, it remains widely recognized and is produced by many older devices and screen recorders.
Windows Media Video
Target formatWMV is a Microsoft proprietary video format from the Windows Media framework. It was common in the early 2000s and still appears in corporate and legacy environments.
Why convert AVI to WMV
Windows Media Video is better supported than AVI Video across web uploads, social networks and consumer devices. Converting trades the niche advantages of AVI for broad playback and fewer "file type not supported" messages. Stream copy (when codecs match) keeps the video bit-identical to the source.
HOW TO CONVERT
AVI → WMV
Upload the AVI
Drop your AVI onto the uploader. Files up to 100 MB run on the free tier without registration.
Stream-copy or re-encode
FFmpeg probes the codecs; if compatible, it stream-copies (no quality loss). Otherwise it transcodes at matching bitrate.
Download the WMV
Fetch the converted WMV as soon as it is ready. Both files auto-delete within two hours.
Common Use Cases
Social media uploads
Twitter, Instagram, TikTok and LinkedIn accept WMV directly; AVI is typically rejected or transcoded with unpredictable quality.
Smart TV and Chromecast
Many TVs play WMV out of the box — AVI often shows up as "unsupported format" or skips audio tracks.
iPhone and iPad playback
iOS Photos, AirDrop and native Safari decode WMV without third-party apps; AVI frequently needs VLC.
Web video embeds
HTML5 <video> tags play WMV universally; AVI often requires clunky object-tag fallbacks or server-side transcoding.
Quality & Compatibility
Stream-copy is bit-perfect: when the codecs inside AVI match what WMV can carry, the frames are copied across without re-encoding and the output is visually identical to the source. When transcoding is required, we target CRF 20–23 H.264 — visually transparent for most content — and keep audio bitrate at 192 kbps AAC.
Tips for Best Results
- Stream-copy beats re-encoding by orders of magnitude — check if your AVI already uses WMV-compatible codecs before picking Advanced settings.
- For social uploads, 1080p at 30 fps strikes the best quality-to-size ratio; 4K is often downscaled server-side anyway.
- Keep the AVI if you plan further editing — transcoded WMV is fine for final delivery but not for intermediate edits.
Frequently Asked Questions
Frequently Asked Questions
Only when it has to. If the codecs inside AVI (usually H.264 or H.265 for video, AAC for audio) are accepted by WMV, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
