noise in concatenating video files

Post by jaggadaku » Sun Mar 19, 2017 9:18 am

Hello there
i am new to ffmpeg and wants to merge video files
i learned about concatenating from here https://trac.ffmpeg.org/wiki/Concatenate#samecodec
now when i concatenates two files two things are happening in merged output file
1. first file is playing well but 2nd file is losing it's quality.
2. merged file is playing very well but in between last second of firstvideo.mp4 and first second of lastvideo.mp4 there is a dot playing or noise like no audio or something

what can i do so that video will look like it is not a two merged videos ?

Here is example file of mine
https://www.youtube.com/watch?v=Yh9FdYPWqJQ
i have merged video of 10 sec and 20 sec = 30 sec
between 10-11 there is little noise so what can i do to remove little noise ?

Show the complete output of:

Code: Select all

ffmpeg -i input1 -i input2
Also show your concat command and the output from that.
