This is probably being caused by the fact that the AVCHD that your Canon records is far more compressed than the HDV that your Sony recorded and is causing your PC to work a whole lot harder to decode it. Most modern PC’s can’t keep up with AVCHD playback at full frame rates. It’s just the nature of AVC compression. Try doing a RAM preview (Shift+B), and if it plays back smoothly then your CPU can’t keep up. If it still skips frames then something else might be causing it. I know that some cameras AVCHD play back smoother in Vegas than others. Apparently, all AVCHD is not created equal.

There is no such thing as “uncompressed MPEG video”. MPEG is a compression scheme and by definitions is compressed. So I’m not sure what kind of file you actually have. If Vegas can’t play it back in sync and WMM can play it, then perhaps you can render it with WMM into a format the is more edit friendly for Vegas (like DV AVI). Normally, Vegas has absolutely no problem syncing MPEG audio on the timeline so something else is wrong with this file and causing Vegas play it back incorrectly.
There is no project wide Pan/Crop. There are scripts that can apply a Pan/Crop to all events or you can nest the project into another project and apply Pan/Crop to the nested project. (Like using pre-comps in After Effects)

The problem with salvaging a file that is incomplete is that the header information which specifies the stream size is probably not written properly because Vegas was still writing the file when it was stopped. It may be quicker to restart the render than to spend days trying to salvage the file.
There is a utility called tsMuxeR that can append AVCHD files together without re-rendering. I would try this and see if it helps you out.
If your area is prone to power outages (like mine) I would definitely get an uninterrupted power supply (UPS). Mine has paid for itself 100 times over in work not lost. Good luck.

> …surely you realise that rendering to DVD involves a fairly substantial compression and loss of quality.
You are talking about compression and bitrate (which is also important) while I am referring to the quality loss due to resizing 5x from SD up to HD. All I can say is to try it and see what you think. Make a Blu-ray and see if you like it. I have no issues with the quality of the DVD’s I produce.

It sounds like the trimmer window is off-screen somewhere. You might try resetting the window layout back to the default (View | Window Layouts | Load Default Layout). If that doesn’t work then you may have to reset your entire configuration by holding down the Ctrl+Shift keys while you start Vegas. WARNING! this will reset all of your preferences to the defaults just like the first time Vegas was installed. This may or may not be desirable depending on how much you have customized Vegas.

There is an icon above the preview to enable and disable effects during preview (4th button from the left). Just click it back on.

I’m using a Sony HVR-DR60 with my Sony Z1U and yes, I record to tape simultaneously as a safety. The Z1 also doesn’t allow remote LANC control without a tape in the transport so even if I didn’t want to, I still have to use a tape when I want to use the LANC. 🙁

I’m not sure why you want to use Blu-ray with miniDV footage? For the best quality I would recommend that you do not output DV to HD. HD has 5x the resolution and your footage will look bad as it’s scaled 5x it’s original size. The best quality is to render in the same quality as the source which is DV/SD.
It’s not clear what you are planning to do with the Blu-ray disc. Is this just for data backup? Do you plan on playing it in Blu-ray player? If it’s just for backup or playing on a PC you can always place the DV AVI file on a 25GB disc as you suggest. If you plan on playing it in a Blu-ray player then you must use the two formats you mentioned (AVC or MPEG2) and be prepared for poor quality from miniDV source.
If you just want a high quality render then render to DV AVI. It is the same quality as your source and you will never get higher quality than what you started with. If you want a playable disc that looks great, make a DVD.

> ….In either case, why could we not use this 24fps format over the 24p format?
Because the 24fps format is for printing to film which really does have 24 discreet frames per second.
> Why will DVDA 4.5 take 24 fps under the 24p+2-3 (23.976fps) format but not the straight 24fps?
Because 24.000 fps is not part of the DVD spec and therefore is an illegal format that set-top DVD players will not know what to do with. 23.976 fps is the standard speed for “24p” DVD’s.
> Why can we not change the frame rate under the optimization function? Is there away around this? Is it even worth pursuing?
It won’t let you change it because that would produce a non-compliant DVD. Now way around it. Not worth pursuing.

I finally got this working. Yea, I know it’s been 6 months but better late than never. I thought I would post here just to document it for the community.
I found a an awesome little utility called InstalledCodec. This will list all of the DirectX filters on your system and allow you to disable and re-enable them. I simply disabled the Nero MP4 Splitter and Boris RED / BLUE can now read ALL of my DV AVI files. According to InstalledCodec this filter is part of Nero ShowTime (which I don’t use).
It would be nice if BorisFX could fix this problem since it’s the only video application on my system that has a problem with this but at least now I have a workaround.
Hope this helps someone else with the same problem.
