This way the video is always converted to progressive internally. Deinterlacing algorithms Several deinterlacing techniques and algorithms may be used, from filters as simple as doubling the lines of the fields to fill the currently missing ones, to massively computationally intensive efforts like motion compensation techniques with the use of neural networks. This also results in the clip running at twice its original frame rate. The following Field Order table is a general rule of thumb of course there are exceptions due to different capture cards, devices, etc. MTS -vf yadif -c: Home Questions Tags Users Unanswered.
