I am trying to get a contant frame rate, and it varies. This is my first
time with FFMPEG, sorry if I'm not up to your level- but I am learning.
I've got most of my problems fixed but these (that I am aware of):
I would like:
-to hold a constant frame rate of 29.97
-Format_Profile :High @ L4.1
-Format_Settings_RefFrames/String : 2 frame2
-BitDepth/String : 24 bit3
My Command Line:
chcp 1252
title Converting Red flash 2 & 1 AVCHD UltraQuality.mpg (1/1)
"C:\Program Files\WinFF\ffmpeg.exe" -threads 4 -i "R:\Dougs
work\2011_05_27\Red flash 2 & 1 AVCHD UltraQuality.mpg" -deinterlace -crf
15.0 -vcodec libx264 -acodec libfaac -ar 48000 -ab 144k -coder 1 -flags
+loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method hex
-subq 6 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71
-b_strategy 1 -threads 0 -b 750k -r 29.97 -s 1280x720 -aspect 16:9 -ac 2
-maxrate 750k -bufsize 500k -level 41 "R:\Dougs work\2011_05_27\Red flash 2
& 1 AVCHD UltraQuality.mp4"
pause
What I actually get:
