SOLVED! Sony XAVC Intra Codec - no stereo output

LeRoi-Casey wrote on 3/26/2020, 2:09 PM

In Movie Studio 16.0 Build 175 (Platinum), the Sony XAVC Intra Codec says 2-channel or stereo audio output but it's rendering with mono audio. Is this a bug?

MediaInfo (and my ears) confirm single-channel audio. (XAVC Long seems to produce stereo audio but this codec appears to produce smaller files so I'm thinking lower quality renders.)

Anyone else able to re-create this (render a small section of a project as Sony XAVC Intra)? Do you get mono output?

I rendered a small section of a MP4 video using Sony XAVC Intra. MediaInfo showed two separate audio streams, each one channel. When I loaded the rendered MXF file back into Movie Studio and played it, it was definitely stereo. I could also hear the stereo when I played the MXF file in VLC.

J-V, yours show mono, not stereo (same as me).

I wonder why different people are getting different results. :/

What do you understand under stereo?

My made file has two mono channels which together are stereo sound, placed back on my Vegas Pro it shows both left and right in one audio track that I can, when I should wish, change in left , right, etc. Look

Also my rendered Sony XAVC intra XMF, has two different channels. You're sure that your original media has two different channels and that you didn't combine them in the timeline like j-v showed.

Thanks for the replies, guys. My media is definitely stereo on the timeline. It renders as stereo using other codecs (including Sony XAVC *Long*) but plays back as mono in my media player when I render as Sony XAVC Intra. I'll try loading the XMF back into Movie Studio to see if it sees both channels.

Which mediaplayer can play those XMF's? My Windows based Mediaplayers can't.

(XAVC Long seems to produce stereo audio but this codec appears to produce smaller files so I'm thinking lower quality renders.)

When it's just for playing, I think you will not see a difference. XMF intras are nice fur further editing, not as endformat.

Since the first release of Sony MXF years back, the audio output has been dual mono.

This was first discussed in 2012-13, around the time of Vegas 7. Just mix your MXF audio at the track level.

SOLVED!

@3POINT - I'm using Media Player Classic 64-bit (aka MPC-HC 64bit). I was wanting to render highest quality video for archiving and for upload to YouTube (since YouTube is notorious for degrading video due to re-compression of uploaded videos).

@Musicvid - thank you! It turns out that's the answer; the codec puts stereo as dual mono. Grr. Isn't it weird that MXF Intra has "dual mono" while most other codecs (including MXF Long) use a single stereo track.

So I loaded my MXF clip back into Movie Studio and could clearly see both left and right channels intact. The media player was simply playing Audio Track 1, which happened to be mono (the left channel). Argh! LOL.

Thanks everyone who replied. Much appreciated. :)

That were @3POINT and I telling you all the time. Your question was if that is stereo OUTPUT and not if it is a stereo channel.
So next time read your own question better or ask another question if you mean something else.

Thanks j-v, 3point and KenB! Much appreciated. Unfortunately it wasn't clear to me that you guys were giving me the answer. I did think my question was fairly clear that I was getting mono audio instead of stereo - whether it be a channel, track or "output". The confusion, of course, is it was stereo but split into 2 separate mono channels. This was made clear to me by how Musicvid answered the question. But yes, you, KenB and 3point lead me to try pulling the rendered clip back into Movie Studio so I could see that, in fact, the left and right channels are there. Thanks again guys. You rock. :)

Glad to be of help.

Sometimes you will get two or three correct answers framed differently, and the one that resonates the best with an individual doesn't detract a bit from the value of the other responses, as @LeRoi-Casey so graciously acknowledged.
