Supports: DV
DV (Digital Video) is the tape format used by MiniDV, Digital8, DVCAM, and DVCPRO camcorders from roughly 1995 onward. It records at a fixed 25 Mbit/s video bitrate plus 1.5 Mbit/s for 16-bit/48 kHz PCM audio, which works out to roughly 12-13 GB per hour once the AVI wrapper overhead is added. That is generous for editing but punishing for archival storage and impossible to email or stream. Xvid is a GPL-licensed implementation of the MPEG-4 Part 2 Advanced Simple Profile codec — the same family that powers DivX — and it can compress that hour of footage to 700 MB-1.4 GB while keeping detail intact at standard definition.
| Property | DV (Digital Video) | Xvid (in AVI) |
|---|---|---|
| Codec family | DV (DCT, intra-frame only) | MPEG-4 Part 2 Advanced Simple Profile |
| Compression | Fixed 25 Mbit/s video + 1.5 Mbit/s PCM audio | Variable, typically 800-3000 kbps for SD |
| 1-hour file size | ~12-13 GB | ~700 MB-1.4 GB at good quality |
| Native resolutions | 720x480 (NTSC), 720x576 (PAL) | Any; SD recommended for hardware players |
| Frame structure | I-frames only — every frame is a keyframe | I, P, and optional B-frames |
| Audio | Uncompressed 16-bit/48 kHz stereo PCM | MP3 or AC-3 in AVI; this tool pairs with default audio |
| Editing friendliness | Frame-accurate, ideal for cuts-only edits | Good but not frame-accurate without re-encoding |
| Hardware playback | DV decks, FireWire-equipped PCs | DivX/Xvid-certified DVD players, most media boxes |
| Status | Standard finalised 1995; tape stock discontinued | GPL; last release 1.3.7 (Dec 2019); US patents expired Nov 2023 |
| Wrapper | .dv (raw DIF),.avi (DV-AVI Type 1/2),.mov | .avi most common;.mkv also supported |
| Goal | Mode | Setting | Approx 1-hour size |
|---|---|---|---|
| Archive-grade visual quality | Constant Quality | CRF 2-4 (Xvid scale) | 1.5-2.5 GB |
| Everyday playback / DVD-R | Variable Bitrate | 1800-2500 kbps | 800 MB-1.1 GB |
| CD-R fit (700 MB) | Specific file size | 700 MB | ~700 MB |
| DivX-certified hardware safe | Constraint Quality | CRF + max 2 Mbps, 720x480 | 800 MB-1 GB |
| Smallest reasonable | Quality Preset | Low or Lowest, 480x360 | 250-400 MB |
DV records video at a fixed 25 Mbit/s and audio as uncompressed 16-bit/48 kHz stereo PCM at 1.5 Mbit/s. Multiply 26.5 Mbit/s by 3,600 seconds and divide by 8, and you get about 11.9 GB just for the stream; AVI wrapper overhead and timecode push the on-disk file closer to 12-13 GB per hour. That fixed bitrate is exactly why DV is great for editing (no quality variability) and rough for storage.
"Very High (Recommended)" is the default and a safe pick. Home-video tape is interlaced standard definition with motion that's usually low-detail, so Xvid handles it efficiently — moving down to "High" cuts the file size noticeably with very little visible loss. Use Constant Quality with a low CRF only if you want a near-archival second copy.
Most players from the DivX Home Theater / DivX Certified era will play Xvid AVI as long as you keep the resolution at 720x480 or 720x576 (or under), keep the bitrate under about 4 Mbit/s, and avoid Xvid's advanced features like global motion compensation, Qpel, MPEG quantization, and multiple B-frames. The Constraint Quality mode with a max bitrate is the safest setting for set-top compatibility.
It depends on the playback target. DV from camcorders is interlaced (typically lower field first), so leave it interlaced if the destination is a CRT TV or set-top DVD player. Deinterlace only when the target is a progressive-scan device — a phone, modern flat panel via streaming, or YouTube upload — because interlaced video looks combed on progressive displays.
DV stores 16:9 widescreen by flagging the aspect ratio in the stream rather than changing the pixel grid; the frame stays 720x480/576 but is meant to be displayed at 16:9. When converting, keep the original resolution and let Xvid carry the display aspect ratio flag, or resize to a square-pixel frame like 854x480 (16:9) or 640x480 (4:3) so older players that ignore aspect flags still show the correct geometry.
No. Xvid is lossy, and once you compress 25 Mbit/s DV down to 1-2 Mbit/s Xvid you cannot recover the original. The accepted preservation workflow is to capture the tape losslessly to DV-AVI (the bit-for-bit copy of what's on the tape), keep that DV-AVI master on at least two drives, and treat Xvid as the everyday playback copy. If storage is a concern, consider DV to MKV with a lossless codec first, then make Xvid copies for sharing.
Xvid's last stable release was 1.3.7 in December 2019, and the relevant US MPEG-4 Visual patents expired in November 2023. The codec is GPL-licensed and ships with VLC, MPC-HC, ffmpeg builds, and most desktop media players. It's not actively developed anymore, but it's stable and unencumbered for new conversions today.
Pick Xvid only when you specifically need playback on DivX-certified DVD players, older standalone media players, or legacy software that doesn't ship an H.264 decoder. For phones, smart TVs, browsers, and modern editing apps, H.264 in MP4 is smaller at the same quality and universally supported — use DV to MP4 instead. The clearest case for Xvid AVI today is feeding hardware from the late-2000s living-room era.
Yes. Switch Trim from Unchanged to Time Range and set a start time and duration. That's how you pull a 30-second birthday clip out of a 60-minute capture without the long render time of trimming the full hour. Each trimmed clip exports as its own Xvid AVI.
