iMovie ‘06 vs iMovie ‘25: transcoding DV for modern NLEs

DV is simple: 25 Mbps, 4:1:1 or 4:2:0, but modern editors hate it. You need to transcode to an edit-friendly codec.

1. The problem with direct DV in 2026

  • Final Cut Pro (modern) does not support DV natively
  • Premiere Pro transcodes on import (slow)
  • Davinci Resolve works but scrubbing is laggy

2. Best intermediate codecs

  • ProRes 422 LT – 80% quality, 1/3 the size of regular ProRes
  • DNxHD 36 – good for Windows, Avid friendly
  • FFV1 – lossless, for archiving
# Transcode DV to ProRes 422 LT (ffmpeg)
ffmpeg -i input.dv -c:v prores_ks -profile:v 1 -c:a pcm_s16le output.mov
⚠️ Sync warning: If your source has drop frames, use "-vsync 1" to avoid drift.

3. Preserving the "DV look"

If you want the scanline/artifact look, do NOT deinterlace. Keep as interlaced and let the editor handle it. Or use this ffmpeg to simulate:

ffmpeg -i input.dv -vf "telecine=pattern=5" -c:v prores_ks dv_look.mov

Thread: "ProRes LT vs ProRes 422 – which for DV?"

I've been using ProRes 422 (full) but files are huge. Anyone using LT?
LT is fine for DV. DV is only 25Mbps, ProRes LT is ~100Mbps. You're not losing anything.

Thread: "ffmpeg dropping frames on capture?"

Using the command above, I get "drop=5" at the end. Is that bad?
Add "-vsync 1" and "-async 1". DV stream sometimes has gaps.
