Text Watermarking on video without loss of audio and video quality
8 janvier 2021, par Aditya KumarI am using following command to add text watermark on a video file(for mp4, mpg,m4v,flv,mov etc..) :


ffmpeg -i input.mp4 -vf "drawtext=text='Opentext':x=(w-text_w)/2:y=(h-text_h)/2:fontsize=24:fontcolor=white" TextOutput.mp4



For some of the file transformation the property of video file changes. for example- When I tried to add text watermark on a mkv file I got this message :




[matroska @ 0000001867d36ec0] Non-monotonous DTS in output stream 0:1 ;
previous : 2273, current : 1596 ; changing to 2273. This may result in
incorrect timestamps in the output file.




This is one of the issues, i have mentioned here. There are others as well, such as :


- 

- video quality is reduced
- video file size is changed(increses/decreases drastically)
- Audio lagging occurs etc...








So, I want to preserve the quality of video after adding the text watermark. How can I do that ?
