H268?
To be honest, I never used .mp4s much in CS3. I was still using QTs for most final delivery.
In CS4, because QT support isn’t as good, I started using H.264 instead and in CS4 it works better than anything else. Now that’s all I use unless I run into a client who’s computer is so old (or their media player – usually QT – is so outdated) that it won’t play .mp4 videos at all. (I play them in Nero’s media player or QT – though interestingly, QT does not recognize pixel aspect ratios in mp4 clips – so I have to make sure i export FINAL clips in square pixels – no matter how they were shot. Weird that Window Media Player doesn’t recognize .mp4s at all – though I guess that’s deliberate, since their WMV Video codecs from 9 on are based on the mpeg4 standard, but is proprietary, and being Microsoft and wanting to dominate the world, they’re trying to make everyone use WMVs…which I have stopped using almost completely as well.) -
Nope – it’s not the drive. I’ve edited hundreds of hours of DV and HDV on USB drives and never had a problem – until CS4 (I blame the Mainconcepts Codecs I think I read somewhere Adobe switched to – just wish I could confirm that so I could complain about it.)
Since you’ve captured it both ways, does the DV capture Audio stay in sync withe HDV capture Video? If yes then just sync those and use that as your HD source.

I have done edits for very large outdoor screens – vertical. I did them in Final Cut Pro, but the principle is the same. I edited them in a custom sequence set not to the screen resolution, but to some other resolution defined by the show producer – and exported quicktimes and M-Jpegs. Saw them on TV and they looked fantastic – but they have special system for displaying those….
But the main thing is that you should be able to export anything from AME – you just have to make sure you are using square pixels. The only problem with that is that the Plasma TV HAS vertical pixels..ha ha! So actually, if you don’t use the correct pixel aspect ratio, your image will be stretched! I would think. You’ll have to test it and tell us what happened.
I’d still use H.264 at 2.5 to 3.0 Mb/s – that seems to play back well and really looks quite good – but if it must be QT, then try M-JPEG

really – just bad power supplies? What are the symptoms?

And may I add that turing off the auto save feature has got be the craziest thing I’ve ever heard. I’d be dead of a heart attack without the auto save set to every 10 minuets (and even then sometime it doesn’t auto save for an hour and THEN it crashes – as if just to taunt me!)

I have noticed that AME encodes pretty quickly, but takes forever to load the sequences from Premiere (Dynamic Link and all that.) I am on an XPsp3 32bit home made non-compliant system with only a moderately speedy dual core processor, so I’m happy when it just doesn’t crash

So the HDV Video is out of sync with the HDV Audio?
So sometimes HDV video is captured and it’s out of sync. No idea why it just happens sometimes.
I have noticed this more often with HDV capture using HDVSplit AND I have noticed it more in CS4 than I did in CS3.If the sync is out the same amount all the time than you can manually re-sync it and then all should be well. If it drifts out of sync over time, then you are really in trouble.
I am presuming the Audio on the HDV tape is distinct from what’s on the DV tapes and can’t just be thrown way.

Wow!
I was referring to CS4 ad Adobe Media Encoder – but the interface is nearly identical.
Hope it all works out. -
I tried CS4 on Windows 7 Beta (64bit) and it ran much better – and my hardware is
hardly certified for Vista, let alone Windows 7. -
I believe there is an option for this in the H.264 output settings – the last tab maybe? Check them all, I’ve seen it somewhere.
