On a video I am producing, I am overlaying a digital on screen graphic on the lower right corner (branding logo). I am overlaying an 11 second two-tiered lower third at the beginning of the video (Speaker's Name with their title below their name). Later in the video a second speaker is introduced and I am trying to add a second two-tiered lower third for the second speaker. I do this on a weekly basis and everything before the second lower third works like magic. However, the second lower third never appears. Here is the code I am using:
ffmpeg -hide_banner -loglevel 56 -report \ -ss 00:25:00 \ -i 00005.MTS \ -i ./constants/edu_logo.svg \ -i ./constants/name_animation_dr_johnson.mp4 \ -i ./constants/name_animation_dr_halmilton.mp4 \ -filter_complex "[1:v]scale=400:122[logo]; \ [0:v][logo]overlay=x=main_w-overlay_w-80:y=main_h-overlay_h-80[v-l]; \ [v-l][2:v]overlay=x=0:y=0:enable='between(t,0,10.5)'[v-l-a]; \ [v-l-a][3:v]overlay=x=0:y=0:enable='between(t,15,25.5)'[v-l-a-a]" \ -vcodec libx264 -preset fast \ -flags +cgop -pix_fmt yuv420p \ -b:v 2M -movflags +faststart \ -map "[v-l-a-a]" -map 0:a -t 30 my_test.mp4
What do I need to modify to get the second lower third to appear?
