I would like to be able to deinterlace a video by converting full-height frames into half-height fields (where each frame of the output represents one field of the input) at double the frame rate. The way this would work is it would take the top field (or bottom field) first and export it as the first frame in the output file, and then take the next field of the input and output it as the second frame in the output file. Then it moves on to the first field of the second input frame, and outputs this as the 3rd frame of the output. And this continues until the output file has twice as many frames as the input, at half the height of the input, and runs at twice the frame rate as the input. For example: Input Frame1 Field1 ----> Output Frame1 Input Frame1 Field2 ----> Output Frame2 Input Frame2 Field1 ----> Output Frame3 Input Frame2 Field2 ----> Output Frame4
I would also like to be able to do the reverse of this, take a video file who's frames represent fields, and then interlace them so that they actually are fields within frames in the output video, and at the same time cut the frame rate in half. For example: Input Frame1 ----> Output Frame1 Field1 Input Frame2 ----> Output Frame1 Field2 Input Frame3 ----> Output Frame2 Field1 Input Frame4 ----> Output Frame2 Field2 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
