Hello!

Do you have the issue with the 'Game Recording Mode' or 'Screen Recording Mode'?
(What is the name of the recording target?)

Do you always have the problem after 20 min.?

Do you have the problem when you play the recorded video in "a media player or a video editing program"?

I use "Screen Recording Mode"
recording target - Bandicam gives names :
bandicam 2015-12-04 12-41-05-580
bandicam 2015-12-04 14-03-01-667
bandicam 2015-12-07 16-47-43-749 etc.
always between 20 and 21 (22) min. disappears any audio : Windows,You Tube or Win. player...
no sound nowhere after 20 min: media player,Camtasia,Virtual Dub etc.
I think the problem AAC but why after 20 min ?
change FPS,quality,bitrate...I'm tired - lost a lot of time on testing :

22-25 min + testing...(+ how many deleted ?) - I'd like to help
The point of the story : This marked has audio and after 20 min ???
change FPS (23.976) and AAC bitrate (192) look MediaInfo :

with the same setting all others do not have (after 20 min.)???
and maybe this my Win 10 Pro Version 1511 (OS build 10586.17) x64 - the real problem...do not be surprised...
Download and see - here disappears audio to 20 min 20 sec.

we did not understand each other...
I recorded installation programs,operating systems,instructions for audio-video converting etc. and create video tutorials.I let movie just to see when disappears recording sound.Me in principle required only that windows OS (system) audio.Look here (for a demonstration) :

my question : how to start "Game Recording Mode" for this recording full screen ? I think it is not possible or ?
yust info : this problem I noticed a long time ago (April,May) - recorded "Skype" call - also no audio after 20 min.Means that the problem is not in this latest version Bandicam.
I say again,does not matter much...for longer video (20 + min.) use AVI recording option.
Let my thoughts : in MP4 (AAC) audio insert option - external codec - or PCM,AC3 or any codec options - it is easy after converted...or may be installed "quck time" or "iTunes" for AAC - tested...
There's still one problem with the "cuts" (since the inserted x264) but it will in another topic soon,greeting...

PS. if you mean something (me does not mean) on "Game Recording Mode" also has no audio - (here a little later) after 24 min.

Fraps has a "Monitor Aero desktop (DWM)" option to record the full screen of Windows.
However, we don't have a plan for this option at the moment. We will consider it in the distant future.

To record your full computer screen without showing the recording status bar, you may try the solution below:
- Firstly, click the 'Full Screen (Ctrl + Enter)' button (No.1)
- Secondly, click the 'Show / Hide (Ctrl +Alt+H)' menu (No. 5)
- Thirdly, press the recording start/stop hotkey (F12)

Let my thoughts : in MP4 (AAC) audio insert option - external codec - or PCM,AC3 or any codec options

We don't have a plan for external audio codec at the moment. We will consider it in the distant future.


Unfortunately, we don't have a good solution for your issue.
We've added your issue in our bug tracking system and we will keep an eye on this issue.


We're sorry that we couldn't provide a solution.
