ffmpeg overlay + drawtext simple examples

ffmpeg_example.txt

1. Add overlay over entire video. No extra text

ffmpeg -i examplecut.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay" -c:a copy output.mp4

2. Add overlay over for 10 seconds in the middle (5s - 15s in this example)

ffmpeg -i examplecut.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay=enable='between(t,5,15)'" -c:a copy output2.mp4

2b. Add overlay starting from X time until the end (X=5 in this example)

ffmpeg -i examplecutshort.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay=enable='gte(t,5)'" -c:a copy output2b.mp4

3. Add text on top of the overlay

ffmpeg -i examplecutshort.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay,drawtext=fontsize=30:text=ricekab playername:x=(w-text_w)/4:y=(text_h+30)" -c:a copy output3.mp4

Multiple drawtexts can be used in sequence. Font options etc can be found here:

https://ffmpeg.org/ffmpeg-filters.html#drawtext-1

3b. Similar to the overlay, drawtext can be cut to specific times:

ffmpeg -i examplecutshort.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay,drawtext=fontsize=30:text=ricekab playername:x=(w-text_w)/4:y=(text_h+30):enable='between(t,0,10)'" -c:a copy output3b.mp4

4. RECAP - Combining the above

Let's unpack this command in parts to see what we're doing:

ffmpeg -i examplecutshort.mp4 -i overlay.png -filter_complex "[0:v][1:v] overlay,drawtext=fontsize=30:text=ricekab playername:x=(w-text_w)/4:y=(text_h+30):enable='between(t,0,10)',drawtext=fontsize=30:text=tag | otherplayer:x=(w-text_w)*3/4:y=(text_h+30):enable='between(t,0,15)',drawtext=fontsize=24:fontcolor=Crimson:text='Winners Final':x=(w-text_w)/2:y=(text_h+60)" -c:a copy output4.mp4
