I've got a folder of 1080p videos that I'm wanting to encode in 720p. I'm
using the below command to do so:
*for i in `ls`; do ffmpeg -y -i $i -vf scale=-1:720,setsar=1:1 -vf
subtitles=$i -crf 25 -trellis 2 -tune animation -preset veryslow -c:a copy
-f mp4 ../destination/720p/$i.mp4; done*
This should scale the video to 720p, but instead "*ffprobe -v quiet
-print_format json -show_format -show_streams ../destination/720p/video.mp4*"
returns
* "width": 1920,*
* "height": 1080,*
* "coded_width": 1920,*
* "coded_height": 1088,*
This is the relevant output from ffmpeg:
//Input data is clearly 1920x1080
Input
Metadata:
encoder : no_variable_data
creation_time : 1970-01-01 00:00:00
Duration: 00:24:11.97, start: 0.000000, bitrate: 3196 kb/s
Stream #0:0: Video: h264 (High), yuv420p, *1920x1080* [SAR 1:1 DAR
16:9], 23.81 fps, 23.81 tbr, 1k tbn, 47.95 tbc (default)
//Now here's the output
Output
Metadata:
encoder : Lavf56.40.101
Stream #0:0: Video: h264 (libx264) ([33][0][0][0] / 0x0021), yuv420p,
*1920x1080* [SAR 1:1 DAR 16:9], q=-1--1, 23.81 fps, 16k tbn, 23.81 tbc
(default)
It's clear that it never even attempts to set it to 720.
I know I must be missing something, but I can't seem to figure out what it
is. Any help on this would be greatly appreciated!
