Hi, welcome to the Magix forums.

In order to have any chance of being able to help you we need a lot more information from you! Please read this post and supply us with everything requested there; at the moment we know nothing about your computer nor about the version of MEP you are using.

Then, since mp4 is a "container" format (the actual codecs used can vary widely) please tell us a little about the mp4 files you are trying to open in MEP: perhaps the easiest method of doing this is to download and install the free MediaInfo utility, point it to one of your mp4 files and post here the results of the Text view.

Hi,

If you mean that you want video and audio on separate tracks, change the setting under File, Program settings, Video/Audio tab, under Timeline, uncheck Video/Audio on one track.

If you already have some clips on the timeline, select them and do a Ctrl+H or right-click, select Audio functions, Video/Audio on separate tracks.

Hi

In addition to Jeff's and John CB's comments can you clarify what you are actually getting on the timeline when you import the video,

I am assuming that if you play the mp4 in Windows Media Player you do hear the audio, and if you play/preview the mp4 from the Media pool in MEP you also hear audio.

  1. just video only with no sound when playing the timeline
  2. just video only with no sound when playing the timeline however the levels meters in the Mixer (M key) are moving
  3. video with sound that plays, however the audio track is not visible
  4. video sound that plays, however no waveform is visible

Greetings

I've had this problem with MP4s from time to time. I've found that it always involves audio encoded to AAC with a sampling rate of 22050Hz. Strangely MP4s with audio encoded to AC3 at 22050Hz (mostly) seem to work.

On occasion I use any of the free audio/splitter converters around to change it to higher sampling rate - usually as a WAV - although, to be honest, the audio is usually so poor that it's not worth the effort.

Hi John EB, thanks for your reply, when I play the MP4 in media
player the sound is fine.  the problem is 1. just video only with no sound when playing the timeline.  I have set (as per John CB’s reply) the video and sound to be imported as two separate files in the timeline.  When I import the MP4
from the media pool to the timeline (by clicking the Import icon) I can see
each frame of the movie but the second track is just a green line, no wave file
showing.  When previewing, there is no sound playing.

Spec is as follows

Many thanks Dave.

Greetings, I'm pleased to see your problem is resolved, although from your exif info and screenshots I can't for the life of me see how the solution you ticked cured the audio problem, but then MEP continues to surprise me even after 10+ years of use.

AndyW

ps I do notice from the exif that your audio is sampled at 22.05 kHz (or 22050 Hz as I mentioned in my previous post) and, even more curious, it's frame rate is 21.533 fps while the video is 25 fps.

I thought that was only possible when combining separate audio and video to Matroska (MKV).

Hi

@me_again

Have you replied to the wrong topic?

AFAICS the issue is not been resolved.

WRT to the audio frame rate in the MediaInfo data - this is perfectly admissable and has no relation to the video framerate - you will see this 'discrepancy' on standard video direct from a camera.

@dave-h

What is the source of this video - from the MediaInfo analysis it looks like it has been through Handbrake or FFMPEG?

MEP prefers audio with 44.1 or 48 kHz sample rate. I suspect the issue is caused by the low sample rate of 22.05 kHz.

If you have a suitable video converter try converting to standard MP4 video format with an audio sample rate of 48kHz.

John EB - I'm convinced that the topic initially came up with resolved! Either that or …..

With regard to audio frame rate I accept that variable fps is quite common however I've found that MEP is somewhat fussy about whether to accept it or not but it's not really a point for discussion here, merely trying to answer why the OP has no audio in his MP4.

Hi Andy

. . . . I'm convinced that the topic initially came up with resolved! . . . .

No problem.

Agreed - MEP appears to be very fussy about the sample rate of audio requiring either 44.1 or 48 kHz, and the discussion is relevant here, as you say audio is often variable bitrate which gives the lower framerate when calculated as an average over time and MEP does not really care except when it is in side a mpg file then the audio can get out of sync on import.

Hi both, Andy was right, I did click on "solution" by accident but realised quickly and unselected it, sorry for any confusion.

Thanks
