how to use ffmpeg to convert audio without quality loss

As not all video/audio types can be used with every container, trying to copy them to a different container may result in an error, an unusable file, or something which works perfectly. Change the output container to something else (avi or mp4 etc) and Video To Video converter will remux the audio/video for you. When you open an flv with Video To Video Converter you can also choose Direct Stream Copy from the list of conversion presets. Choose an output preset after opening the flv file, change the output codec to ffv1 (lossless) and the audio to either 'copy' or 'pcm'. For example ffmpeg -i audio.ogg -c:a libmp3lame -q:a 0 newfile. You can probably go from flv to MKV that way without converting anything.Īlternatively, convert the flv to a lossless AVI/MKV/MP4 and use it for editing/converting with Sony Vegas. If you want to minimize quality loss, use a high bit rate. content while keeping the wanted video/audio/subtitles at ZERO quality loss AKA lossless. ok as i said if its not possible to get same quality can somebody tell me good settings in ffmpeg to make mp4 with high quality closest to original one or can i convert flv to other format (with no quality loss) but that is friendly to sony vegas ? I wouldn't have a clue what Sony Vegas will work with, but MKVMergeGUI can open flv files and save the output as MKV. 4 GB) npz Kami no Tou - 04 (US BD REMUX,1080p) EB072BF9.
