I also use TM 4.2 for CG work using 32 bit TGA’s. Works well. If you need tighter integration of a CG within Vegas Cayman Graphics have a couple of versions, Power CG Plus and Power CG RFs that work with Vegas as plugins and can be accessed from the timeline. Similar to Titlemotion but they ‘aint cheap when compared to the price of Vegas!

Well I’m lost. Because as Ed says Vegas, or SF for that matter only shows you a representation of what a file contains re data, neither program alters the files. Both programs are ‘non-destructive’ in their file handling unless of course you overwrite a file. If with a fresh boot of either program the files are being seen with inverted phase then that means the files are incorrect. This can only happen if they were recorded incorrectly or have been overwritten with their phase altered. So I can’t begin to work out what’s happened here if the above is not the case.

Making sure I understand things correctly here. Are you saying that one track of a stereo pair, i.e. the left track is 180 dgrees out relative to the right track or vice-a-versa? If this is correct then you wouldn’t hear it correctly if played over a mono speaker setup or mono TV. It would sound low, thin and reedy probably as it self cancels. If you are listening to a correctly wired stereo speaker setup, speaker leads not incorrectly reversed on one channel, you would still hear it quite clearly even though the phases are opposed. What I can’t quite get my head around is that you appear to be saying is that Vegas is somehow inverting the phase on one channel only. I cannot see how this is possible. Just in case it isn’t something else have you checked the audio track ‘switches’ to make sure that the ‘invert phase’ switch isn’t on? This switch obviously forces phase inversion which could cause problems if the track involved is now mixed with other tracks. Loss of audio level in out of phase stereo tracks is normally only heard when the L + R tracks are summed together down to a mono mix. Is this how you are monitoring? The more info you can supply the better.
All I can add is that when we see these problems that in ninety percent plus of cases where there is out of phase audio it has been the result a] out of phase cabling during recording in the first instance, b] out of phase cables during ingest to system, and lastly, c] out of phase audio playback due to out of phase wiring in the edit suite.

This sounds very odd! How are you ascertaining that the tracks are out of phase, phase/correlation meters? If so by how many degrees are they going out?

Had exactly the same problem with v6.0d a few weeks back. Have no idea where those standard three audio plugs went. Reinstall over the top didn’t fix it. I had to uninstall 6.0 and do a complete new install to get them back, pain in the butt! Lost a heap of presets that I had made plus had to reinstall quite a few of my 3rd party plugins. Blame Bill G!

If the final product is going out to std def DVD I would originate in std def myself. I have done a couple of jobs in HDV using the Connect HD capture and then editing in Vegas but to be quite honest I can’t see any benefit unless you want to ‘future proof’ the job for later HD WMV renders or such like. As the HDV format is widescreen you normally end up rendering out a widescreen std def DVD which ends up letter boxed on a 4:3 set anyway. Sure it fits the 16:9 sets out there but they are still in the minority here, though the market is changing quite rapidly, last Aussie industry figures saying 22% penetration into the household market for widescreen sets to date.
So I think if your end market is primarily 4:3 shoot 4:3 and get the best out of the 4:3 screen real estate. The other thing I find is unless clients supply you with 1.5K or upwards in still images anything smaller gets stretched to fit the 1440×1080 HDV timeline and usually suffers far worse that if the graphics were used in a std def job. All our TV jobs now are widescreen, network demands, yet still we have to run with 14:9 shoot and protect with a 4:3 safe graphics area. For most commercial clients where the product is going to end up on projectors, DVD’s and PC’s we find it best to go 4:3 std def. Less comments like, “Why is my picture squashed?” just because they don’t know how to set up their projectors etc.
I to am curious as to any comments on the V1, anyone? As for prices haven’t seen any yet.

Yes, understand the problem now. MPEG files requires a lot of grunt to decode realtime for editing. Have a look at MPEG Streamclip from Squared 5. I think it can convert MPEG4 to DV, not 100% sure but it’s worth a look as it will convert most formats to most formats. If not check around the web as there is sure to be some app somewhere that can do the job for you. Streamclips URL is:

The footage you are playing back, was this captured with Vegas? I have seen a couple of instances with footage that was captured by another app, Canopus in this case, putting heavy CPU load, like 65-75%, on a PAL Vegas system and when I checked this out the footage was listed as upper field first. The same footage recaptured with Vegas then came in as lower field first and the CPU load dropped, as mentioned in one of the other replies, to around 10-15%. Like the other reply I am using Asus MOBO’s on two units and not a problem. You don’t have any antivirus or disc defraggers running in the background at the same time do you? Some antivirus programs by default constantly monitor file access by other programs and if this is happening it can cause major CPU usage and slowdown. Auto defragging can also cause similar problems. Can’t think of much else to suggest!

Just a long shot here but do you have a high number set in your Dynamic RAM preview under Options/Preference/Video tab. If so try setting it down to 16MB or even 0MB and see what happens.
