Step 1: Open the VLC and select “Media”. Click on the convert/save. Step 2: On the next window that appears, select “add” and choose the video file (MP4) to be converted.

24 lip 2019 · 5. You don't need to do this in three steps: ffmpeg -vn -sn -dn -i input.mp4 -codec:a libmp3lame -qscale:a 4 output.mp3. This creates a MP3 file with a VBR (variable bit rate) of 165. Check here for more options. Arguments (beware, the order matters!): -vn disables all video-streams from the input. -sn disables all subtitle-streams from the input.
30 mar 2013 · Drag MP4 into window. If the original audio track in the MP4 file was MP3, you can go directly to ‘Audio->Save’ and get the original, untouched audio with no quality loss. If it's not MP3 (probably AAC would be more likely), change the ‘Audio’ drop-down from ‘Copy’ to ‘MP3 (lame)’, hit ‘Configure’ to set the bitrate (you ...
22 sie 2019 · Then, you can just queue the video files for upload to YouTube. Among the solutions listed on the page: FFmpeg, then upload files to YouTube. ffmpeg -loop 1 -i picture.jpg -i music.mp3 -shortest -acodec copy video.mp4 Loop accordingly for all mp3 files, then upload all the resulting video files.

2. grawity's answer is great! Just to add to it, if you would like to extract the audio from an MP4 and put it in an MP3 and keep the metadata (MP3 ID3 tags) then you can do this: ffmpeg -i input_file.mp4 -map_metadata 0 -id3v2_version 3 -vn -b:a 128k -c:a libmp3lame output_file.mp3.

10 maj 2013 · 90. Yes, it might actually make sense if you are being forced to change formats. If you have a file with 95kbps in a highly efficient format, to retain the same quality, a relatively inefficient format as mp3 needs a higher bitrate. Of course you will never get anything back that was lost in the first place.
11 mar 2013 · However, there's a big caveat: this only works if the audio and video codecs are supported in the target (MP4) container, which is the case for H.264/H.265 and AAC, for example, but not for many others. Also, subtitle format support for MP4 is different from MKV, and actually quite restricted, so this command may fail.
I have a load of audio files (about 1000) which I want to convert from m4a to mp3 so I can use play them on a CD player which has a USB port. I tried doing something simple like: ffmpeg -i FILE.m4a FILE.mp3 but this seems to reduce the bitrate to a very low value, which isn't what I want.
I have a folder with various media files such as .m4a, .aac, .mp4, etc. and I want to invoke FFMPEG to convert them all to .mp3 using the basic FFMPEG command ffmpeg -i myfile.m4a myfile.mp3. Can you show me a basic example of what this .bat text file would look like?
