Duplicated keyframe
Hello,
After changing the bitrate of a video with the two pass I get a duplitace keyframe…I get two 0 timestamps…
The commands that I use is:ffmpeg -i $1 -an -pass 1 -passlogfile $2 -vcodec libx264 -vpre slow_firstpass -b 120000 -threads 0 $3 -v 0 2>&1
ffmpeg -i $1 -acodec libfaac -ab 128k -pass 2 -passlogfile $2 -vcodec libx264 -vpre slow -b 120000 -threads 0 -y $3 -v 0 2>&1
What could I do to erase this duplicate

“Can you post a sample of the terminal output showing this?

“You shouldn’t need the passlogfile when using x264 as it generates one itself. Maybe try to remove this…..
