I recently encountered what at first glance appears to be an anomaly with DGIndexNV reporting and delivering circa 50fps from a file which is supposed to be PAL 25i (25 frames per sec, 50 fields per sec).
My workflow in this specific case is
1. OTA capture into a .ts (for timeshifted viewing)
2. automated VideoReDo QuickStreamFix (QSF) into a .mp4
3. run DGIndexNV over the QSF file to create a .dgi
4. create a vapoursynth script to core.dgdecodenv.DGSource and filter the video
5. use ffmpeg to convert/re-mux the audio with the filtered/deinterlaced video into
I am getting stuck at item 3 since DGIndexNV say's the QSF .mp4 file is 50fps, hence later encodes/muxes go at 50fps and as a result the audio sync is amusing but unhelpful
I went back to v225 however that was still doing the same thing.
I did update VideoReDo recently, perhaps that's related, however
- mediainfo says 25fps on the QSF file
- media players recognise 25fps in the QSF file and play it correctly
The source and QSF files and the DG .log/.dgi and mediainfo logs are here:

Pointing me in the right direction would be much appreciated, as my workflow is now at a standstill
mediainfo reports the QSF file as
