ffmpeg speed up video - Windows
19 March 2019, by Flash ThunderIn manual it says:
ffmpeg -i input.mkv -filter:v 'setpts=0.5*PTS' output.mkv
But when I run:
ffmpeg -i input.mp4 -filter:v 'setpts=0.5*PTS' speedup.mp4
I get an error:
[AVFilterGraph @ 0000000002500600] No such filter: 'setpts=0.5*PTS'
Error opening filters!Not sure if it means that filter can’t be opened at all or simply this filter is not available.
How do I run it correctly? Or maybe my release does not support it, then where can I get the release that would work right? Win32/x64 binary

How to change video speed by ffmpeg?
17 May 2019, by Pooja JadavI’m using ffmpeg for video filter.
But, When I changed video speed, that time I got issue
-
Audio is longer than video :
ffmpeg -i INPUT.mp4 -filter:v setpts=0.5*PTS -shortest -y -preset ultrafast OUTPUT.mp4
I want to set audio’s length same as video’s length.
- shortest = to extend audio streams to the same length as the video stream
In my case,
shortest
is not working. Video file and audio file, both are different and then after merging in a video file. Video’s last frame stop and audio is continued working. -

How to speed up ffmpeg when working with multiple files?
6 May 2019, by OBXI have
100,000
files which I need to convert from.mp3
to.wav
. However, at the moment it takes1
minute to convert10
files each of1
hour duration.Here’s what I tried :
for i in *.mp3
do
ffmpeg -i "$i" -acodec pcm_s16le -ac 1 -ar 16000 "stm/$(basename -s .mp3 "$i").wav"
doneAlso tried
GNU parallel
as well, which takes same time as well :find ./set/ -name "*.mp3" | parallel 'ffmpeg -i {} -acodec pcm_s16le -ac 1 -ar 16000 {.}.wav'
Is there a better hack to process the same in less time ?
