Quote from: AQUAR on March 19, 2014, 11:31:40 AMI would deinterlace before resampling.50 fps might mean 50 fields per second.Deinterlacing such a source with linear blend gives 25 frames per second.

Quote from: AQUAR on March 19, 2014, 12:27:56 PMRe issue 3:Hard to say what is going on.Cutting AVC is best done at reference frames (might help!).

Quote from: AQUAR on March 20, 2014, 12:41:56 AMAre you sure that the -> & <- buttons move the time scale by O.2 second?These navigation buttons are for moving to the next/previous frame.At 25 frames per second (50 interlaced fields) the time scale should really only move 0.04 seconds.50 frames per second is 0.02 seconds - maybe you misread!

Quote from: AQUAR on March 20, 2014, 12:41:56 AMSo normally you can define a cut/edit segment with frame accurate marker points.As mean points out, re-encoding that segment from AVC to Xvid should also be frame accurate.But just copying that segment would need a smartcopy function for frame accuracy (not available with 2.6).
