Supports: DV
DV (Digital Video) is the intraframe codec standardized as IEC 61834 in 1995 and used by virtually every consumer and prosumer miniDV camcorder shipped from the late 1990s through the mid-2010s. It records at a fixed 25 Mbps video plus 16-bit/48 kHz PCM audio, which works out to roughly 13 GB per hour — large because every frame is a standalone I-frame with only mild 5:1 compression. MPEG (typically MPEG-2 video with MP2 audio in the.mpeg/.mpg container) is the codec family behind DVD-Video, ATSC and DVB over-the-air broadcast, and many legacy set-top boxes. Common reasons to convert:
| Property | DV | MPEG (MPEG-2 in.mpeg/.mpg) |
|---|---|---|
| Standard | IEC 61834 (1995), SMPTE 314M (DVCPRO) | ISO/IEC 13818 (MPEG-2, 1996) |
| Compression | Intraframe DCT, fixed 5:1 ratio | Interframe (I/P/B frames), variable 10-40:1 |
| Video bitrate | Fixed 25 Mbps | Typical 2-15 Mbps (8 Mbps DVD average) |
| Audio | 16-bit / 48 kHz PCM (uncompressed) | MP2 or AC-3 (lossy) |
| Frame size | 720×480 (NTSC) / 720×576 (PAL) | Same SD frames; HD MPEG-2 up to 1920×1080 |
| File size per hour | ~13 GB | ~2.7-3.6 GB at DVD quality |
| Editing | Frame-accurate, low CPU | Re-encode required on most cuts (GOP boundary issue) |
| DVD-compatible | No (must be transcoded) | Yes (MPEG-2 is mandated) |
| Best for | Tape capture, raw editing source | Archive, DVD authoring, broadcast |
| Mode | What it does | Pick when |
|---|---|---|
| Quality Preset | One-click Highest → Lowest preset (default "Very High") | You want a sensible default with no tweaking |
| Specific file size | Auto-tunes MPEG-2 bitrate to hit an exact MB target | Sizing for a DVD-R (4.37 GB single-layer) or share cap |
| Constant Bitrate (CBR) | Fixed bits per second across the whole video | DVD authoring, broadcast-style predictable streams |
| Variable Bitrate (VBR) | Spends more bits on motion, fewer on static scenes | Smallest file at the same perceived quality |
| Constant Quality (CRF) | CRF slider for consistent perceived quality per scene | Mixed-content tapes where motion varies a lot |
| Constraint Quality | VBR with a hard ceiling bitrate | DVD compliance (peak ≤ 9.8 Mbps, average ≤ 7 Mbps) |
| Bitrate (video) | 1 hour output size | Quality | Use case |
|---|---|---|---|
| 9-10 Mbps | ~4.1-4.5 GB | Near-DV, DVD ceiling | Highest-quality DVD-R, master archive |
| 6-8 Mbps | ~2.7-3.6 GB | Commercial DVD-Video | DVD authoring, family-archive default |
| 4 Mbps | ~1.8 GB | Watchable, soft on motion | Multi-hour DVDs, space-constrained archive |
| 2-3 Mbps | ~0.9-1.4 GB | VHS-like, visible artifacts | Preview, web compatibility builds |
If you also need to shrink the result further, follow up with Compress MPEG. Heading to modern devices instead? See DV to MP4 — H.264 inside an MP4 container plays on every phone, browser, and smart TV. For non-destructive editing before conversion, use Video Cutter.
Some quality is lost — DV is near-lossless intraframe at 25 Mbps; MPEG-2 is interframe lossy at typically 4-9 Mbps. The drop is small at 8 Mbps and above (most viewers cannot tell on SD content), more visible at 4 Mbps and below, and obvious under 3 Mbps. For an archive master, set the Quality Preset to "Very High" or use Constant Quality with a low CRF; for shelf-space recovery on routine home video, 6-8 Mbps is the sweet spot used by commercial DVDs.
If you have the disk space, keep an untouched copy of the.dv file as your archival master — it is the closest to the tape signal you will ever get, and re-encoding always discards information. The MPEG-2 (or MP4) becomes your sharing/playback copy. Many video archivists follow this two-tier rule: master in DV or FFV1, derivative in MPEG-2 for DVD authoring or MP4 for web/mobile.
By default, the converter preserves the DV native resolution — 720×480 (NTSC, 29.97 fps interlaced) or 720×576 (PAL, 25 fps interlaced). Both are valid MPEG-2 frame sizes and are exactly what DVD-Video expects, so no scaling is needed for DVD authoring. If you only plan to play the result on modern devices, you can upscale to 1080p under Video resolution, but it will not add detail that was not in the SD source — it just changes the storage size.
The MPEG-2 file from this converter is the right codec, audio format, and resolution for DVD-Video, but a hardware DVD player will not play a raw.mpg from a data disc — it expects the full DVD-Video directory structure (VIDEO_TS folder with.VOB,.IFO,.BUP files). Use a DVD authoring tool (DVDStyler is free, ImgBurn for ISO builds, or Apple's older iDVD) and feed it this MPEG. The MPEG-2 inside complies with the spec, so no re-encode happens at authoring time.
Yes — MPEG-2 supports interlaced encoding natively, and the converter preserves the DV field order (lower-field-first for NTSC DV) automatically. If you plan to play the result only on progressive-scan displays (every modern TV, phone, computer), deinterlacing during conversion produces a cleaner image at the cost of a one-time re-encode. The default keeps interlacing for DVD compatibility.
Yes — under Trim, pick Time Range and enter a start time and duration for each segment you want. Run the conversion multiple times (or batch-load multiple Trim ranges) to extract individual scenes from a continuous 60-minute tape capture. For more flexible cutting, use Video Cutter first to split the.dv, then convert the segments separately.
MP2 (MPEG-1 Audio Layer II) is the legacy default and is mandatory in the DVD-Video spec for PAL discs; NTSC DVDs typically use AC-3 (Dolby Digital). Both are supported MPEG container audio codecs. MP2 has the broadest legacy-hardware compatibility; AC-3 is preferable if your target is an NTSC DVD or modern home-theater receiver. The DV PCM source (16-bit/48 kHz) maps cleanly to either with a single re-encode.
Two to watch for. First, DV uses 4:1:1 chroma subsampling (NTSC) — slightly weaker color resolution than MPEG-2's standard 4:2:0. The horizontal-vs-vertical chroma layout differs, and edges of saturated color can show faint ringing after conversion. Second, DV's intraframe structure means every frame is a clean I-frame; MPEG-2's GOP structure (typically I/P/B with 15-frame GOPs) introduces motion prediction. On extremely high-motion footage at low bitrates (under 4 Mbps), you may see brief blocking on fast pans. Both are mitigated by encoding at 6 Mbps or higher.
If your target is DVD authoring, legacy broadcast equipment, or a hardware media player from the 2000s, MPEG-2 is correct — it is the codec those systems decode in hardware. For everything else (phones, smart TVs, modern PCs, web upload), MP4 with H.264 produces files roughly 2-3× smaller at the same perceived quality and plays on every device made since 2010. See DV to MP4 for that route. The.mpeg/.mpg path makes sense specifically when MPEG-2 compatibility is the requirement.
