[HELP] Video stuttering after processing
#1
Question 
I am trying to get a video to upload to youtube from a PAL VHS tape.

I am following this flow, following this video https://www.youtube.com/watch?v=pKYNqZdqawc
1) Acquisition with Virtualdub and Dazzle DVC100.
2) Deinterlacing and conversion to Apple Prores via Hybrid
3) Color enhancement with DaVinci Resolve and compression to h264

Step 1 all ok, I got a video file of about 30GB and it is to be deinterlaced with top field first. The video looks good, has no stuttering and has these characteristics:

Interleave, duration                     : 10  ms (0.25 video frame)
Interleave, preload duration             : 229  ms

Step 2, I set really few options in hybrid, but if I open the resultant prores video with VLC there is so much stuttering! The video is full of jerks that make it annoying to watch
This are all the options that I change from default

Any help? Thanks
  • What Hybrid version did you use?(Windows/Mac/Linux 32/64bit + versions number)
    Windows 2024.09.29.1

If you need the debug infos I relaunch the process, it's about 5h  Big Grin
