| I have raw avi footage captured with bandicam.. I accidentally left it recording for 15 min and I needed to cut some extra time off so I wanted to use Vdub for this. I load the video up, select Video: Direct Stream Copy, Audio: Direct Stream Copy, and Save As AVI. When it's done saving.. my video is in slow motion?  The raw stuff is 30fps and I left vdub fps settings at default so that shouldn't be messing with anything.. any help? |

| When you open the original video and you look in File > File Information..., at Video stream > Frame size, fps, you should see the number of frames per second (you say it is 30 fps). When you open the resulting video, after the Direct Stream Copy, the number of fps - in File Information - should be the same (also 30 fps). You say that this resulting video plays in slow motion, so the "fps" should logically be less ? At my opinion, the only thing that can play a role in this case, are the settings in Video > Frame rate... These should be set at "No change ..." and "Process all frames" when performing the Direct Stream Copy. |

| All of what you say is true, yet i'm still getting slow motion out of the new trimmed video.. |

| Try selecting Audio > No audio and saving the AVI. I ran into a problem once where the audio had to be recompressed before saving, else the result was super slow motion. |

Audio > No Audio fixed it.. but then I have no audio.  So that's not exactly a solution. Is there a way to fix it but keep the audio? You say 'the audio had to be recompressed', how do I do that? |

| In the Audio menu, you first have to choose "Full processing mode" instead of "Direct Stream Copy". Secondly you must select an audio codec and appropriate settings, via the Audio menu > Compression... for example: MPEG Layer-3 / 128kBit Via Audio > Interleaving... you can "Enable audio/video interleaving", choose a preload of 500 msec. and an interleaving every 1 frame. |

Is this a codec issue? I have one file that I am adding audio and overlays to, and I am processing it with the x264 video codec and no audio codec. I am also having the slow motion issue. Should I be using an audio codec; which one? And should video/audio be on full processing mode or direct stream copy? |
