Xmedia recode vs avidemux9/24/2023 Quote from: styrol on March 24, 2013, 09:39:43 AMĭo not use Avidemux if you simply wanna get a M4A audio file, it cannot output it. So in the first step, I would then probably have reencoded the audio as/to PCM (beware - filmsoundtrack files in PCM get large, in the gigabyte range) that doesn't work for me, no PCM output. Adobe Media Encoder: Adobe subscribers' pick to convert videos in a broad selection of video formats. Freemake Video Converter: A paid and easy video converter available on Windows 10. Any Video Converter Free: A free video converter with audio special effects. That would of course be two unnecessary re-encodings, so loosing somewhat in quality. Avidemux: An open-source video editor that supports video conversion. In Linux, I use cat: cat file1.mpg file2.mpg file3.mpg > newfile.mpg. I did not try, as I was happy then, but maybe I could have loaded the Videofile with mp3 soundtrack, and then encode it again with video:copy and audio encode:AAC. copy/b file1.mpg+file2.mpg+file3.mpg newfile.mpg. The recommendations may vary depending on content type and application area. These are based on material I've read over the years, and from what I've seen used in the industry. When sampling up: Use Bicubic or Lanczos filtering. Now it plays fine in VLC, and I can easily switch to and fro German/ French. 3 Answers Sorted by: 33 TL DR When sampling down: Use Lanczos or Spline filtering. Using FFMpeg or Avidemux may also allow you to recover the mkv when its been corrupted in the way. Then I loaded the German-language file, and could choose the mp3-file as (secondary) audio-track. MKV to MP4 Lossless and quick with XMedia Recode. Then I loaded that new video and did "save audio", saved as french.mp3. I loaded the (French) video, did Video:copy, and audio:encode with lame(mp3). I got nowhere with this problem with avidemux, until I resorted to this trick : I had a problem somewhat similar to the original poster's, trying to rip AAC from one mp4 file (French) and add it to other mp4 file (German) as secondary audiotrack. I can only offer a quick&dirty workaround, only to be used if the audiotrack in the final video does NOT need to be AAC. I don't even know if that "ff-prompt.bat" called for Windows-default-commandline, or did it bring it's own shell ? That someone else must explain, I never used ffmpeg directly/ through commandline.
