Ubuntu reduce video size with ffmepg and change format
27 juillet 2015, par Arnas PečelisI want to watermark, reduce weigth, resize and change format for selected videos.
Also I need to keep quality as high as it possible.Now what I have :
ffmpeg -i prepared/video.mp4 -i units/video_watermark.png -filter_complex overlay=10:10 -codec:a copy moved/video_test.mp4
and I’m watermarking video, but the quality drops a lot. Also I have :
ffmpeg -i prepared/video.mp4 -s 1280x720 -b 512k -vcodec mpeg1video -acodec copy
but also I need to reduce weight also as lot as possible. The reconstructed videos will be shown as movies online. My question would be - is it possible to do it one line and change format to .mp4 ?
PS. I have constructed command :
ffmpeg -i downloaded/movie/movie.avi -c:v libx264 -acodec libfaac -b:a 64k -preset ultrafast -vf "movie=units/video_watermark.png [watermark]; [in][watermark] overlay=10:10 [out]" -movflags faststart prepared/movie.mp4
but it returns me error :

Scaling and stacking 2 videos
31 octobre 2019, par Gambit2007I have 2 inputs and I want to scale, crop and put them on top of each other at the same time. My command should look something like this :
ffmpeg -i input1 -i input2 -filter_complex crop=10000:5000:1000:0,scale=3840:1536 vstack output.mp4
I know I need to use chaining (?) but I tried to look it up online and couldn’t really get it to work.
So what would be the correct syntax the scale and crop both inputs and then put them vertically on top of each other while using ’-filter_complex’ only once ?
