First, everything on the timeline is an event. There are no clips on the timeline.
I use the Noise Reduction in Sony Sound Forge – but I sure wish that Sony would add it to Vegas because it really works.
FX can be applied in three places. In the Project Media you can add an FX to the media clip (this is the only place in Vegas where a clip exists). The FX applies to every event made from that media clip on any track. You can add an FX to a track which applies to all events on that track. Or you can add the FX at the event level which applies only to that event. Audio FX can be added to any audio bus or the output master bus.

That’s not interlacing – that is Rolling Shutter artifacts. Rolling shutter is endemic on CMOS chips because of the progressive scanning nature of the electronics. The image is made from scanning top to bottom, much like you read a book. Rolling shutter artifacts occur when something changes in the frame in the time it takes the chip to be fully scanned from top to bottom,
New Blue FX Essentials 3 has a Rolling shutter filter.
There is also rolling shutter correction in the Vegas stabilize plugin. You can get rolling shutter correction independent of stabilization in the Vegas plugin by setting stabilization to nil.
(I’ve never needed these tools since my cameras are CCD)A CMOS sensor electronically scans the image from the top to the bottom of the sensor. Different portions become light-sensitive at different moments in time as this process proceeds down the course of the full frame until the entire frame is exposed. If the camera moves, like the whip pan you describe, or with camera vibration, the image moves as the sensor is scanned.
A CCD sensor incorporates a global shutter that exposes the entire image sensor simultaneously. The entire frame is exposed and begins gathering light; when the predetermined “shutter speed” has elapsed, the sensor stops gathering light and turns its current exposure into an electronic image. At the start of exposure the entire sensor starts gathering light; at the end of exposure the light-gathering circuitry is turned off and the contents of the sensor are then “read out” to become an image. Motion during the frame only results in a blurred image.

If chkdsk /f fixes ANYTHING, then you should plan on replacing that drive soon.

I need to correct what I said earlier – yes you can re-encode a file in a lossless codec, but you pretty much have to be doing nothing to the video in the process. No frame rate change, no bitrate change, no color correction, and no editing. any of these requires a recompress. I meant above that any recompression of the file will have data loss. The Lagarith codec is pretty good for lossless encoding.
But the basic question remains unanswered. Upgrading Vegas should not take away any formats that once worked in an earlier version.

Thanks, ten years of using Vegas and I still learn something new every day.

The way that FAT and NTFS works is that each file is broken into chunks called clusters. As the data fills one cluster then the O/S writes a pointer to the next cluster then starts putting the next chunk into the next cluster. This is repeated until the file’s contents are all written. The last cluster is terminated with a lot of zeros to finish filling the cluster. Chkdsk makes sure that a file can be navigated from cluster to cluster. If it can’t because of a bad cluster, then Chkdsk will attempt to reconstruct the data (there’s some error-correction built in), and if successful, it will then write a new file with the suffix .chk. Chkdsk also looks for cases where two files have the same target cluster in their chain. I haven’t seen those since the days of FAT32. There are other things that can go wrong with a file cluster chain that chkdsk can find, but not always fix. I think that the SMART utility does more, but SMART won’t rebuild a file structure.
As you noticed in your example, once chkdsk started reporting failures a complete drive failure wasn’t far behind.
Incidentally, the filename is in the first cluster. When you erase a file, all you are really doing is changing the first character of the filename to a null. (Not to be confused with moving the file to the recycle bin which is another topic). Unerase programs only need to find that null first character, and if the program can find the end of the file, then an unerase is easy. If you have written something to the drive and used one of the clusters formerly used by the erased file, then recovery is pretty much impossible.

I like John’s first solution, but why not use an embedded project instead of a rendered file?

First – NO conversion program or re-encoding process is loss-free. Some get close, but there is always a quality hit. I don’t care what the marketing people say, lossless recompression is impossible. Good codecs can recompress with no observable losses, but there is data loss.
I have never heard of Dxtory, but looking at the specs on the website, it looks like you can select the encoding codec. Try Lagarith.

Chkdsk checks the file structure on the drive, but problems there usually cascade all over your software landscape pretty fast. Sfc /scannow (in windows run) supposedly scans the system files for integrity, but in all the years I have been into PC’s I have never seen sfc find anything wrong.
This is just a band-aid until you find your problem driver. Autosaver will automatically hit CTRL-S for you no matter what you’re doing. You can set it to 10 or 15 seconds so if you do have a crash, you don’t have far to go to recover.

First, Unmanaged Exception is almost always a driver error. Reinstalling Vegas won’t fix driver problems. Have you always had nVidia on this PC or did it have an ATI display adapter at one time? Have you changed other hardware?
Are any of the devices in Device Manager marked with a yellow “!”?
You will only have the MS SQL server process installed if you are using the Media Manager.
Try this, hold Ctrl + Shift while starting Vegas to reset all preferences and delete cached data prior to loading the program. If you have recently installed new hardware (especially a new graphics card), this is necessary because Vegas may be loading settings for your old hardware.
