    Missing audio from MSI Afterburner footage

    Naossoan

      Hi guys,


      I just installed the latest version of MSI Afterburner and was very happy to see that you are now able to set two audio sources to record. I'm not sure when this feature was added so forgive me if it was in a previous version but I have not used it in a while. In the past since I did not have a Stereo Mix option on my sound card and I am using a USB headset (so Stereo Mix is useless anyway) I was forced to use Virtual Audio Cable and set up some audio repeaters to get everything I wanted to record. Kind of a pain.


      Anyway, I recorded a game of DOTA2 last night after having set MSI Afterburner to record my headset and microphone. I had tested this out to make sure it was recording both sources prior to doing this by just making a short few seconds recording with some blah blah blah and opening the uncompressed .avi file in Windows Media Player. I confirmed both sources were recorded.


      The resulting DOTA2 recorded game is approximately 43 GB in size. When I open this file in Windows Media Player I can hear both sources of audio just fine. Meaning the in-game audio as well as my microphone.


      However when I open this file in Adobe Premiere Pro CS5.5 the only audio track showing up in there is my microphone audio. No in-game audio is present throughout the entire recording. I thought maybe it was an issue with the MJPG codec that Afterburner uses...such as I had in the past when using Sony Vegas but the video seems to be playing just fine as well as my mic audio matching up properly.


      So I tried using AVS4YOU's Video Converter to convert the raw file to .wmv format and opened that up in CS5.5 but I still have the same problem.

       

      Why would the audio tracks be working in the raw file when I open it in WMP but there is no in-game or computer audio present when opened in CS5.5?

       

      If anyone else is using these pieces of software and has any input can you please send it my way? Thank you.

            Well I had posted on another forum as well so I wasn't about to type the whole thing out again. And it looks fine to me when I look at it. None of that code is even visible.

              Well...I certainly can't force you to.

               

              But neither am I under any obligation to help, so...

                Maybe someone else will not be so pretentious enough to look beyond the fact that I was looking to not waste my time by typing out the question again and maybe consider helping me.

                 

                Good job turning me off of this forum forever over something completely stupid and nonsensical.

                  When you import the original AVI file into Pr, select it in the Project panel and go to File>Modify>Interpret Footage and see how many audio channels Pr thinks the file has.  Post back with that info and/or provide a screenshot.  It may also help to examine the AVI file with MediaInfo and GSpot

                    Yes I'm sorry about the profanity but this guy is starting stuff with me for no apparent reason. Who cares if I copy pasted!!

                     

                    Thank you for your suggestions, I will try this right now!

                     

                    EDIT:

                     

                    I'm not sure this is the correct information. It does say L and R channels however this is not my problem. The problem is that one of the audio sources/track is completely not there. The footage was only recorded in Stereo though, not 5.1 surround.

                     

                    In the past when I have edited captures with multiple audio sources it would have an audio track for the in-game audio and another track for my voice recording. I'm not sure if MSI Afterburner combines them into 1 track or if it leaves them separate tracks, but either way if it combined them into one track then the in-game audio would just be in the same track with microphone audio, which I have also seen in the past. And regardless if it is a separate track or combined track the in-game audio is working when I load it into WMP. So confused >_<

                     

                    EDIT AGAIN:

                     

                    OK so this is weird. I went into MSI Afterburner (the recording software) and was fiddling around with the settings. I turned off the second audio track (my mic) and only set it to record the sound exiting to my speakers (well, a USB headsets to be more precise).

                     

                    When I load this footage into WPM it plays fine, with sound.

                     

                    When I load the footage into CS 5.5 it plays sound but then the sound CUTS OUT for some reason, then when I go back to the beginning of the clip and play it again, there is NO SOUND at all! So...there is sound but it's not playing. What the heck!?

                      I'm not sure what's going on with the audio in Premiere so I am switching back to software I am familiar with. I wasn't able to get the video I already made this post about working in the other software either, but I was able to get it working with some other settings in MSI Afterburner.

                       

                      These settings appear to work in Premiere as well, but the audio keeps disappearing for some unknown reason. Like it will play for a couple seconds then just cut out/disappear, even if I stop and play the clip from the beginning.

                       

                      In MSI Afterburner there is a setting called "Downmix multichannel audio to stereo" with a tickbox, and a drop down box with "stereo mix" and "stereo rip" selectible. If I record footage without this ticked the audio will not play in my other software either, but if I tick it then both audio tracks are there and they both play, and they are 2 separate tracks making editing of them easier still.

                       

                      Sorry Adobe but I don't know why the audio from my clips is present but not playing or playing then cutting out for some reason. Won't be getting my business in the future.

                       

                      Thank you for your assistance

                        Did you wait for the audio to conform?  If your clip is long clip, it may take a few minutes for Pr to finish conforming the audio to 32-bit float, which is Pr's working audio format.  Check the bottom right corner of the UI -- there's a progress bar there during conforming.

                          Yes it was doing this even on clips that are only ~5-10 seconds in length that I was testing with.

                            In Pr, does the audio import as a single stereo track, or does it import as dual mono tracks?  Either way, use Clip>Modify>Audio Channels (in CS6) to force Pr to use the opposite.  You have to make the change before you add the clip to a sequence.

                              I checked these audio channels and they appear to be right to me. I also loaded the item in the sequence window then dragged it to the New Item button which to my knowledge should set it to match the original and this did not work either.
