We've got 1920x1080 source We want to letterbox top and bottom to create 2.39 aspect ratio, maintaining that within the original 1920x1080 Then over the composited letterboxed picture we want to burn in timecode and subcaps We're currently achieving the letterbox by means superimposing a photoshop file that handles the letterboxing ffmpeg \ -i Source.mxf \ -i Source.psd \ -filter_complex "[0:v][1:v] overlay=0:0:enable='between(t,2,10)'" \ Dest.mxf But when adding the overlays we run into trouble ffmpeg \ -i Source.mxf \ -i Source.psd \ -filter_complex "[0:v][1:v] overlay=0:0:enable='between(t,2,10)'" \ -vf "drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='00\\:59\\:57\\:00':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=Subcaps.ass" \ Dest.mxf Error is [vost#0:0/mpeg2video @ 0x12ba058f0] Filtergraph 'drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='00\:59\:57\:00':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=Subcaps.ass' was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph. -vf/-af/-filter and -filter_complex cannot be used together for the same stream. Is there a way to properly configure this? Thanks
