I have been using WinFF tool to convert panasonic default .MTS videos into mpeg videos. However, I am not happy with the quality of the mpeg video output. Could some one tell me if there are any other tool for Ubuntu or the options that should I use in WinFF for getting high quality mpeg output.
This site has a great tutorial on how to do it, and includes a helpful bash script that joins the MTS files before starting, as apparently not doing so can cause problems.
If you want to experiment before jumping into his instructions, you can try the following command. This creates an x264 AVI, you can easily change the output format by changing the
libx264 part below to
ffmpeg -i your_file.MTS -acodec copy -vcodec libx264 -crf 21 -r 30000/1001 -deinterlace -vpre lossless_medium -y -threads 0 output_file.avi
I used jozzas' method explained above, and converted a 124MB test MTS file to a 55 MB MP4 file.
A two-pass conversion using Handbrake resulted in a 19 MB file, again, with no loss in quality.
So, which do you want, the command-line version which reduces file size by 55%, or the GUI version which reduces file size by 85% ?
