Step 1 Generate text video ffmpeg -f lavfi -r 30 -i color=black:1280x720 -f lavfi -i anullsrc -vf "drawtext=fontfile='/path/to/font.ttf':fontcolor=FFFFFF:fontsize=50:text='Your text':x='(main_w-text_w)/2':y='(main_h-text_h)/2',fade=t=in:st=0:d=1,fade=t=out:st=3:d=1" -c:v libx264 -b:v 1000k -pix_fmt yuv420p -video_track_timescale 15360 -c:a aac -ar 48000 -ac 2 -sample_fmt fltp -t 4 intro.mp4įor WebM, replace -c:v libx264 with -c:v anycodings_concat libvpx, -c:a aac with -c:a libvorbis and anycodings_concat intro.mp4 with intro.webm. You'll have to generate a 4 second video anycodings_concat with dummy audio matching the parameters anycodings_concat of the existing video, including anycodings_concat timebase, and then use the concat anycodings_concat demuxer with streamcopy. Stream #0:1(eng): Audio: vorbis, 48000 Hz, stereo, fltp (default) I am new to ffmpeg and any help will be anycodings_concat appreciated.Įxample ffprobe information for mp4 below: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'input.mp4':ĭuration: 00:00:03.84, start: 0.042667, bitrate: 1117 kb/s (optional) to make the text fade in/out.need to maintain the quality (resolution, bitrate, etc).I have some videos either in mp4 or webm anycodings_concat format, and I'd like to use ffmpeg to add 4 anycodings_concat seconds to the start of each video to anycodings_concat display some text in the center with no anycodings_concat sound.
