    I just tested a capture from DVCAM where left channel is wireless on person talking and right channel is camera mic

    the captured file plays correct in EDIUS and WMP

    the only way I can get a wrong result is by swapping left and right speakers

      I concur. I did 10 test captures and all are perfect.

        That's precisely why I'm sure that there's something wrong here — FireWire connections either work correctly or they don't!

        Attached is the same camera footage, captured by FireWire in my 'other' system, and exported to .wmv. I've imported it into the EDIUS machine, and put it on a new timeline — it plays 'correctly' in both EDIUS and WMP. (The version captured in my new EDIUS system won't.)

        I've been through everything I can find in the machine relating to audio, and can find nothing unexpected — this is, after all, a brand new system, in which (in theory) nothing has been 'tweaked'.

        No... to me there is only one conclusion, and that is that SOMEHOW the FireWire capture on this machine is the wrong way round... impossible, I know, but nonethless what's happening. I need to find out how and why.

        I shall go back to the supplier and ask him to think again. Thanks for the suggestions here.

          Does either Liquid or Edius allow remapping the IEEE-1394 HDV input stream audio channels; i.e., reverse channel 1 and channel 2, during capture?
          Any chance this is a wierd effect of Win 7 vs. leagacy driver?

            I'm not aware of any IEEE-1394 remapping in 'the other editor' — it was never necessary. Equally, if it's possible in EDIUS, then I have no idea how... and as this was a new installation in a new machine, I have no thoughts on why it might have been done.

            I've re-contacted the supplier to see if he has any ideas, based on the things we've discussed in this thread, and will report back.

              I might be on to something — the HDV (f2) capture preset.

              I tried capturing the original tape from my spare Sony HVR HD1000E camera — no difference.

              I cloned the section of tape from the Sony V1 into an SD version in my PD150 using a FireWire link... as it transferred the audio remained correct.

              I then captured that into the same EDIUS project, using the DV 16:9 (f4) preset... it came in correctly, and stayed correct when I put it on the timeline with the others.

              I confirmed that by going back to the V1 and forcing it to down-convert to DV, taking this in with the same (f4) preset. Again, it was correct.

              I then took the original test footage, put it back in the V1, and captured it using the 'HDV - Capture as MPEG' (f3) preset. Again, this is fine in the bin and on the timeline, with the audio correctly positioned... the end result I wanted.

              BUT... even weirder — although it captured alright, it monitored wrongly when being digitised. The f2 preset does this too, but it STAYS wrong. Let's not go any further there!

              So does the problem somehow lie in the HD capture preset (f2)? Can it be changed? My supplier has subsequently said that he recommends the (f3) preset, which I'll use from now on (despite the apparent odd monitoring effect during capture).

              I confirm that the whole project was made to the HD1080 (1920x1080 50i, 16:9 8bit) preset, and PAL.

                who made your capture device presets? did you make them or download them?

                I never tried the downloaded ones, because it is rather quick to make one and it will be as you need

                  Those presets are made and then assigned hot keys. Thus your Fx number really make no difference. It sounds like someone made an incorrect preset. Delete the bad one and make another one.

                    Ah — being new to EDIUS I wasn't aware that these presets (and their hot keys) didn't come bundled from Grass Valley.

                    I'll have another word with the supplier who made them up.
