I don't know what that is, so I guess it's on default?

I'm still looking for a solution. The audio is out of sync with a simple program like this:

using (VisioForge.Controls.VideoEdit.VideoEditSlave ve = new VisioForge.Controls.VideoEdit.VideoEditSlave())
{
ve.Input_AddVideoFile(videofile, -1, -1, 0, VisioForge.Types.VFVideoEditStretchMode.Crop, 1);
ve.Input_AddAudioFile(videofile, -1, -1, 0, videofile, 0, 0, 1);
ve.Mode = VisioForge.Types.VFVideoEditMode.Convert;
ve.Video_Renderer = VisioForge.Types.VFVideoRenderer.None;
ve.Output_Format = VFVideoEditOutputFormat.MP4_H264;
ve.MP4_Audio_Format = VisioForge.Types.VFMP4AudioEncoder.AAC;
ve.MP4_Audio_AAC_Version = VisioForge.Types.VFAACVersion.MPEG2;
ve.MP4_Video_Sequential_Timing = VisioForge.Types.VFH264TimeType.Encoded;
ve.Output_Filename = dir + "\\output.mp4";
ve.ConsoleUsage = true;
ve.Start();
}

Any thoughts? Thanks.

Hi

Did you try Modern encoder for MP4 instead Legacy?

Hi Roman,

How do I do that? I tried changing VFAACVersion to MPEG4 but the files created then, can't be played in Quicktime or VLC.

Thanks

Hi,
I found the setting to use the modern encoder. But it doesn't solve my problem. Any other thoughts?

Thanks.

Hi,
This problem seems to only happen when the input audio is aac. Any ideas?

Thanks

Hi qakmak,

The quality is fine on my testvideo's.

I think maybe it's good enough for you. But I still can hear there is some sound quality loss, some differences.

My video's are mostly talking heads. So you're probably right.
