How to compress output file using FFmpeg - Apple ProRes 422
10 septembre 2015, par user1526912I am new to video encoding and trying to encode a music video for the apple itunes video store.
I am currently using FFmpeg for encoding.
My source file is mp4 file type and file size=650MB
I encode the file using the Apple ProRes 422 (HQ) codec and output a mov file.
ffmpeg -y -i busy1.mp4 -vcodec prores -profile:v 3 -r "29.97" -c:a mp2 busy2.mov
I am trying to encode the video according to the following specs :
● Apple ProRes 422 (HQ)
● VBR expected at 220 MbpsEncoded PASP Converted to ProRes From
1920 x 1080 1:1 HDCAM SR, D5, ATSC
1280 x 720 1:1 ATSC progressive29.97 interlaced frames per second for video sourced
Music Video Audio Source Profile
● MPEG-2 layer II stereo
● 384 kpbs
● 48KhzThe file is encoded perfectly fine however the output is 6Gb in size.
Why would the file be so large after encoding ?
Am I doing something wrong here ?
