Hybrid converted video loses 5 seconds compared to original..?
#3
Sorry about the log,  I now have learned how to create one (attached).

I turned Avisynth on,  same 13:56 result.  (image attached)


Info:

Input: NTSC DV AVI 720×480, 29.97i, BFF, no audio.

Base: no trims; start=00:00:00.000, end full length.
Config → Input:
Ignore delay from input: OFF
Fix positive/negative delays: OFF (both)
FFmpeg vsync handling: drop (also tested: cfr/passthrough/vfr/ → same 13:56 result, drop didn't work either)
Filtering → Vapoursynth → Misc → Source:
Prefer LWLibAVSource over FFmpegSource2: ON (or, if testing AVS: “Always use Avisynth” + AviSource)
(De-)Interlace/Telecine (VS):
Input scan type (detected): bottom field first
Auto deinterlace handling: QTGMC (Vapoursynth)
QTGMC: Bob ON, Preset Slower, Source matching 2xrefined, EZKeepGrain 1.00
Crop/Resize: Resize 640×480, PAR → Square Pixel (1:1).
Video encoder/container: FFV1 lossless → MKV.
Observed: Output 13:56; original 14:01. Fade-in @ 0:21 source, 0:16 output.
