VP17 Imports 1 audio track from a video file containing 2 audio tracks

Devaizter wrote on 12/7/2020, 9:16 AM

Hello everyone! My first post here! :)

I have an issue I stumbled upon and I was hoping that someone might help me out with it.

I have an MP4 video file in HEVC format that has 2 audio tracks which are both AAC LC. MediaInfo confirms this as well.

When I imported the file to Vegas Pro 17 Build 452 (Latest) a message appeared and said "HEVC has been successfully activated!".

The file is now on the timeline but it shows/imported only 1 audio track Instead of 2.

How do I fix it and make all audio tracks to appear?

My Specs:

CPU: Intel Core i9 7900 X-Series

GPU: Gigabyte AORUS GeForce GTX 1080 Ti Waterforce Xtreme Edition 11GB GDDR5X

RAM: Corsair Vengeance 32GB (16x2) DDR4 3000MHz CL15

Operation System: Microsoft Windows 10 Professional 64 Bit English (Latest Update)

Thank you!

Devaizter / Igor.

There are two channels on 1 track

"two channels on 1 track" a two-channel stereo (left & right) audio event

FWIW, there is a preference option to import interleaved stereo audio to two separate tracks, which would be useful if two separate mics (host and guest for instance) was recorded to a stereo file.

If VEGAS shows 2 audio streams in the media properties, you can add mp4 file to a new track and manually select the second stream

That's not the case I'm having, It shows only 1 Track with only 1 Channel. I tried to import another MP4 file which has 2 audio tracks and it successfully put all 2 audio tracks separately on the timeline (this file format is AVC though).

I tried other MP4 AVC files and they all work as they should, but MP4 files with HEVC format only shows 1 track & 1 channel on the timeline.

but MP4 files with HEVC format only shows 1 track & 1 channel on the timeline.

That is not what I'm seeing with a 4K HEVC file from my GoPro 7 Black, look

@Devaizter

might be time to post the mediainfo of your file https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

@Devaizter

Or can you upload a small piece of your video file to dropbox or something so that we can try it?

Vegas normally does not like VFR video. You might have to convert that to fixed.

Frame rate mode                          : Variable
Frame rate                               : 60.000 FPS
Minimum frame rate                       : 54.778 FPS
Maximum frame rate                       : 67.568 FPS

But it loads correctly in VP18 here with both audio tracks. I will test it on another PC I have which runs VP17

Illusion wrote on 12/7/2020, 5:16 PM

I tested the file on VP17 build 452 and it imports only the first audio track. An alternative would be to extract the audio stream with FFmpeg or VLC and add it as separate audio file to your project.

Illusion wrote on 12/7/2020, 5:23 PM

Here is the FFmpeg command to extract the missing audio track from your video file. It will create a .mp4 file which will contains only track #2. Add it back to your project. Replace the input filename as needed.

ffmpeg -i "Preview File.mp4" -map 0:2 track2.mp4

john_dennis wrote on 12/7/2020, 6:13 PM

I must be living a charmed life. Vegas Pro 17-452 opens all three streams from the original download file.

I do get that ugly green bar at the top of the preview screen, though.

rraud wrote on 12/8/2020, 8:56 AM

I am only getting one audio track with VP-16.

j-v wrote on 12/8/2020, 11:16 AM

I agree @rraud and @Illusion.
I tried on laptop in VMS17 Pl, VPro 17 and VPro 18 and saw this
VMS 17 Pl

VP17

VP 18

My proposal to @Devaizter if he really want to have those different audiotracks is to try VPro 18 latest build.

michael-harrison wrote on 12/8/2020, 4:41 PM

@john_dennis have you mucked about with the internal settings in your VP 17? fwiw I get the same results in 452 as everyone else. Single audio channel even though it's clearly got 2

Musicvid wrote on 12/8/2020, 11:02 PM

Handbrake encodes multiple audio streams.

It's too early to remember if I changed an Internal Setting. Anything in particular you had in mind? This is the fresh image that I saved when I installed Vegas Pro 18. I just restored it about a week ago to try new scanner drivers.

I run an AMD Video card.
Vegas Pro 18-373 is installed on the same machine.

@john_dennis *this*

"Name: so4compoundplug.dll Folder: C:\Program Files\VEGAS\VEGAS Pro 17.0\FileIO Plug-Ins\so4compoundplug"

Turns out *I* still had an internal change on my laptop that I'd never made on my main machine and forgot that I hadn't rolled back for my laptop

Anyone who has disabled so4... for stability reasons will have trouble loading files with multiple audio streams

Not sure what you're pointing out here :-)

I haven't.

@john_dennisThat's my point. That's why it was working for you.

Once I re-enabled so4, it worked for me too

Has that plugin something to do with that file? With me it is another, look

And with you??

That is the .dll that Vegas 17-452 uses to open the problem file on my system.

This is what Vegas 18-373 uses to open the file on my system:
