I'm trying to apply a scaling and chromakey effect to different segments of a video and then combine those segments again into one.
To improve the time and performance I have developed a program that creates all the filters in a single command. The plan is simple, I have a video * .mov recorded with a green screen and a background * .jpg, 1. I first prepare a couple of backgrounds with blur effect from the JPG image 2. I then apply chromakey to make the green part of the video transparent 3. I trim the video to which I applied the chromakey in several time segments and to each segment I applied a scale and crop and I overlay it to one of the backgrounds prepared in step 1 4. Concatenate all segments already processed. When I execute the resulting command it gives me the error the command is this: ffmpeg -i "C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\chroma\green1.mov" -i C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\fondos\sc.jpg -filter_complex " [1:v]scale=iw*3:-1,crop=w=iw/3:h=ih/3:y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3), boxblur=7:2[fondo_3IZQ] ; [1:v]scale=iw*4:-1,crop=w=iw/4:h=ih/4:y=(ih-oh)/3:x=(in_w-out_w)/2,boxblur=6 :2[fondo_4CEN] ; [1:v]scale=iw*5:-1,crop=w=iw/5:h=ih/5:y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3), boxblur=5:2[fondo_5IZQ] ; [0]chromakey=color=#83BD46:similarity = 0.1 : blend = 0.05,selectivecolor=reds=0 0 0 -1:yellows=0 0.1 0 -0.5:greens=0 0 -1 0:whites=0 0 0 -0.7 [vid] ; [vid] trim=start=0:duration=0,setpts=PTS-STARTPTS,scale=iw*4:-1,crop=w=iw/4:h=ih/4 :y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3)[vid_0] ; [fondo_4CEN][vid_0]overlay[toma_0] ; [vid] trim=start=0:duration=3.41933,setpts=PTS-STARTPTS,scale=iw*3:-1,crop=w=iw/3: h=ih/3:y=(ih-oh)/3:x=(in_w-out_w)/2[vid_1] ; [fondo_3IZQ][vid_1]overlay[toma_1] ; [vid] trim=start=3.41932988166809:duration=2.85067,setpts=PTS-STARTPTS,scale=iw*5: -1,crop=w=iw/5:h=ih/5:y=(ih-oh)/3:x=(in_w-out_w)/2[vid_2] ; [fondo_5IZQ][vid_2]overlay[toma_2] ; [toma_0] [toma_1] [toma_2] concat=n=3:v=1:a=1:unsafe=1 [v_concatenado][a_concatenado]" -map [v_concatenado] -map [a_concatenado] "C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\chroma\green1_FINAL.mov" when I execute it ffmpeg says: [Parsed_overlay_20 @ 0000000000404100] Media type mismatch between the 'Parsed_o verlay_20' filter output pad 0 (video) and the 'Parsed_concat_26' filter input p ad 1 (audio) [AVFilterGraph @ 0000000003527a00] Cannot create the link overlay:0 -> concat:1 Error initializing complex filters.
