How to create VCR video effects | Video Recorder Play Rec Replay Eject Pause FF Rew VFX
Today, we show how to create different video effects to mimic the functions of an old VCR. The functions we demonstrate are: Play, Record / REC, Replay, Eject Pause, Fast Forward / FF, Rewind / Rew. All parameters can be customized to suit your needs.

❶ VCR Play function.
Note: To implement the Record / REC or Replay functions, simply replace the .png in the command
→ ffmpeg -i input.mp4 -vf "movie=Play.png[layer];[in][layer]overlay=20:0[out]" output01.mp4
with:
-i input.mp4 = Reads file «input.mp4» and …
-vf "movie=Play.png[layer] = … imports «Play.png» calling it [layer].
[in][layer] = Loads, in order, the original video [in] and the Play.png [layer]…
overlay=20:0 = … and overlays the picture layer at position x=20, y=0 from the upper left corner
[out] = … calling the result [out].
output01.mp4 = Outputs finally the whole to file «output01.mp4»
❷ VCR Eject functions
→ ffmpeg -i input.mp4 -vf "movie=Eject.png[layer];[in]fade=out:150:1[in2];[in2][layer]overlay=enable='if(between(t,2,7),lt(mod(t,2),1),0)'[out]" -af "volume=enable='between(t,5,10)':volume=0" output02.mp4
with:
-i input.mp4 = Reads file «input.mp4» and …
-vf "movie=Eject.png[layer] =
[in]fade=out:150:1[in2] = Turns now the original video to black after 5 seconds (~150 frames) calling the output [in2] and …
[in2][layer]overlay=enable='if(between(t,2,7),lt(mod(t,2),1),0)'[out] = … overlays the Eject picture [layer] on the video [in2] between seconds 2 & 7 making it blink every 2s during that time.
-af "volume=enable='between(t,5,10)':volume=0 = Turns the audio off after 5 seconds and…
output02.mp4 = … outputs the final result to file «output02.mp4»
❸ VCR Pause function
→ ffmpeg -i input.mp4 -i Pause.png -filter_complex [0:v]loop=loop=60:size=1:start=29.97*3,setpts=N/FRAME_RATE/TB[v2];[v2][1:v]overlay=enable='between(t,3,5)'[v];[0:a]aloop=loop=60:size=48000/29.97:start=3*48000,asetpts=N/SR/TB,volume=enable='between(t,3,5)':volume=0[a] -map [v] -map [a] output03.mp4
with:
-i input.mp4 = Reads file «input.mp4», …
-i Pause.png = … imports picture «Pause.png» …
-filter_complex = … and starts a series of complex filters.
[0:v]loop=loop=60:size=1:start=29.97*3,setpts=N/FRAME_RATE/TB[v2] = Stops and loops the video after 3 seconds for 2 seconds …
[v2][1:v]overlay=enable='between(t,3,5)'[v] = … and overlays the Pause.png [1:v] on it during that time (between seconds 3 and 5).
[0:a]aloop=loop=60:size=48000/29.97:start=3*48000,asetpts=N/SR/TB = Stops and loops now the audio after 3 seconds for 2 seconds …
volume=enable='between(t,3,5)':volume=0[a] = … setting the audio volume to 0 during that time (between seconds 3 and 5).
-map [v] -map [a] = Stitches back together the resulting video [v] and audio [a]…
output03.mp4 = … and outputs the whole to file «output03.mp4»
❹ VCR Fast Forward / FF Function
→ ffmpeg -i input.mp4 -i FF.png -filter_complex "[0:v]setpts=0.5*PTS[v2];[0:a]atempo=2.0[a];[v2][1:v]overlay[v]" -map "[v]" -map "[a]" output04.mp4
with:
-i input.mp4 = Reads file «input.mp4», …
-i FF.png = … imports picture «FF.png».
-filter_complex = … and starts a series of complex filters.
[0:v]setpts=0.5*PTS[v2];[0:a]atempo=2.0[a] = Accelerates the input video [0:v] and input audio [a:0] by a x2 factor and …
[v2][1:v]overlay[v] = … overlays the ff.png on top of the video.
-map "[v]" -map "[a]" = Stitches back together the resulting video [v] and audio [a]…
output04.mp4 = … and outputs finally the whole to file «output04.mp4»
❺ VCR Rewind / Rew function
→ ffmpeg -i input.mp4 -i REW.png -filter_complex "[0:v]reverse,setpts=0.5*PTS[v2];[0:a]areverse,atempo=2.0[a];[v2][1:v]overlay[v]" -map "[v]" -map "[a]" output05.mp4
with:
-i input.mp4 = Reads file «input.mp4», …
-i REW.png = … imports picture «REW.png».
-filter_complex = … and starts a series of complex filters.
[0:v]reverse,setpts=0.5*PTS[v2];[0:a]areverse,atempo=2.0[a] = Reverses first and then accelerates the input video [0:v] and input audio [a:0] by a x2 factor and …
[v2][1:v]overlay[v] = … overlays the REW.png on top of the video.
-map "[v]" -map "[a]" = Stitches back together the resulting video [v] and audio [a]…
output05.mp4 = … and outputs finally the whole to file «output04.mp4»
