Someone mentioned that SF10 was able to save MP4 video. Mine will not, I open a video, normalise the sound but when I save I lose all video. Have tried "saving as" (chose *.mp4) and also just "save". The result is the same - a black screen with music! Have had to re-do 3 videos after losing them - Can anyone help?
Welcome to the Magix Sound Forge users forum @Roman-Rencki.
Which version of Sound Forge-10? Is the video attached?? If you have an AVC codec installed, you can re-render the file in SF.. however.. a generational loss with take place. Magix versions of SF-AS (Audio Studio) can allegedly 'mux' in new or replacement audio. I am not aware of any version of SF Pro supports muxing and none of the SCS (Sony) versions can.
That being said, when I need to replace audio on a MP4 video, I render an AAC (.mp4 or .m4a) audio only file and mux in the replacement audio with a third-party app such as MeGUI, My MP4Box or Avidemux. The picture remains untouched so there is no quality loss.
Much appreciate your reply - thanks. (SF 10 build 252)
I'm still at a loss why, if I open a video and work on the audio part, I can't just save it back from where it came still with the video part intact.
I have had good success "normalising" audio in videos using "MP4gain", but having SF in my computer would like to use it if possible.
I do not know about Audio Studio, but SF Pro-10 has the options to 'Save as' a Sony or MainConcept AVC/AAC (.mp4) In either, select to 'Custom' button in the 'Save as' window and check-mark 'Include video'
As I previously stated, the video quality will be reduced with the re-render... how much depends on the bit rate and other settings. Muxing in the replacement audio is far better in terms of preserving picture quality.
Taking onto account your comments about re-rendering, I have found a work-around.
Once the video is in SF, I can "remove video" and edit the audio.
I am then able to move that modified audio file into my video editor, replacing the already separated/deleted audio track (from the same original video file)
Thanks again for taking the time to respond.
