By applying the video filter tblend=all_mode=average,framestep=2 to a video and targeting an FPS half of the source input, you can achieve frame blending. However, how can I use tblend to achieve frame blending without dropping the FPS into half similar to the one shown below? The first 30FPS output uses tblend normally while the second 30FPS output uses tblend with a frame offset. Next, the two are then interleaved to produce a 60FPS output. Are there any ways to do this without producing any intermediate file?
