Audio from Panasonic GH2 (1280 x720) 50P

[Geoff_C]

Just testing some .mts files from a GH2 camera. Track 3xV + 3xA. Audio channel map shows all audio tracks set to stereo. When I drop clips on to time line video goes into 1V but the audio insists on using 1A & 2A. Expanding the audio tracks show a single waveform in each of 1A & 2A.
OK I can work with it by re-mapping 1A & 2A as single channel L & R but I would prefer a single stereo audio channel
Settings-system-project Preset
Frame: 1280x720 Rate: 50.00 Field Order: Progressive (greyed out)
Stereoscopic Edit: Disable Rate 48K 2ch
Settings-Project settings
Video Preset; HD 1280x720 25P (no option to change to 50P)
Frame Rate: 25P (greyed out) Should read 50P
Audio as per Settings -System

What am I doing wrong? Saw a thread about 50P setup recently but simply can't find it now.

Thanks Geoff

When you drag from bin there are several places where you can drop the clip
just move it up and down slowly before releasing the mouse button and you will see the various positions the audio can go to.
I think Anton`s website may show you how

Thanks John
I recall a recent posting from Anton showing 50P setup. Seem to recall that you cannot start from 50i and change to 50P. The 50p must be from a predefined system pre-set.
Update: Started a new project and timeline setting now match the preset.1280x720P (50)
Tried dragging slowly and can now get the audio into 1A (set stereo) but only one channel visible.
Reopened an old HDV 1440x1080 50i project and find the .mts file will drop into 2V and 1A as a stereo file. Can also drop into 1VA correctly. Likewise Vegas accepts the .mts audio as stereo.
'MediaInfo' confirms 1280x720P 50fps 2 channel Front LR
All audio tracks are mapped stereo.
At the moment I'm just trying to get my head round a new camera and see how Edius handles the files on my pc.
Just hoping these aren't senior moments creeping in.

If you want a single stereo track, right click on one of the Audio tracks and Select the bottom option, Audio Source Channel (Stereo).

@GV
Didn’t quite work like that on my system but pretty close. R Click in clip audio(timeline)-> properties. Then select radio button ‘stereo ’and apply.
If I now go to a clip in the Bin but not yet on the timeline and then open properties-> audio tab. The stereo radio button is correctly checked. It changes once it is dragged to the timeline and needs to be changed back and re-applied.

I don’t really fancy doing this to hundreds of clips. Edius bug or something wrong my end?

correct, the audio track patch needs to look like this one

Try my directions again and look at Anton's link. That will solve your problem.

[Geoff_C]

Thanks I stand corrected. I've improved my knowledge of Edius but it still doesn't work.
1) New project 1V plus 1A & 1B(both stereo). Clip properties show stereo.
Drag clip to time line & both audio channels used and audio waveform (unbalanced) suggests stereo. I can force either channel into stereo but cannot get both waveforms into one channel.

2) New project just 1VA. Prior to dragging clip in set A to stereo. Drag clip in and only 1 audio waveform showing.

There is good news. I normally work in HDV (taped based) 1440x1080 50i
I f I create a new HDV project based on a single VA track and drop clip on the timeline all is well. Likewise if I open an existing HDV project & add 50P media the audio sits in a single stereo audio channel and looks stereo.

For the time being 1289x720P is not a major priority as most media will be 50i and a normal HDV preset will be used but I would like to resolve matters. Poor consolation but the clips go straight into a Vegas 50P project.

Thanks for your help it is appreciated. @ anton. eventually found your .pngs showing 50P setup.

Have .pngs of ProjPreset, ProjSettings & Channel map. Can't attached them

Sorted. Open new project. Set 1A to stereo. Close project & Edius. Reopen Edius and add files to Bin & Timeline. Doesn't sound right but it has worked 3 times in succession.

[antonsvideo]

we need to see a screenshot of your timeline including track headers

this forum allows you to attach when you scroll down and click manage attachments, png images work well

[Geoff_C]

png's as requested

[antonsvideo]

if sequence mapping is also on stereo, then it should work like this

[Geoff_C]

Thank you. Your .mp4 was just what I needed, explains everything.

Now to get my head round colour matching the GH2 to the A1e in camera but that's another ball game.

I'm amazed at how much I've learnt from this forum.
Once again thanks.

Update:
This gets more interesting. Got hold of some sample video from a new JVC camcorder 1080 50P.
Opened an old project and made a new 50P preset and then closed Edius. Re-opened Edius and created a new project using the new 50P project. Audio spread itself over 2 audio tracks despite forcing 1A stereo. Removed clips from timeline and deleted audio tracks so that only 1A was present. Added clip 1 and the 1A showed correctly the two waveforms. Added 2 more audio tracks and then pulled more clips to the timeline. These clips dropped into 1A perfectly.
Repeated the exercise on a laptop. Same performance.
If I introduce these 50P clips into an existing HDV 50I timeline based projects they drop in perfectly every time. The key seems to be in getting clip one seated properly.

[GrassValley_SL]

The key is the mapping with the track patches.

The clip will follow the mapping set by the patches on the timeline.

I work 4 channels P2 and never have an issue. The clips folow the map set by the patches.

[Geoff_C]

Think I'm having a senior moment this end.

Are you saying that despite mapping the 1A to say 4A channels stereo within the Project Preset one then needs to check that the track patches actually read A1/2. i.e. each track is carrying L & R channels.

Surely this would imply a bug in Edius which I find hard to believe.
