Problems with v 6 and 7

Well, this is quite interesting to me. I tried to deconvolve an WMV7 video in version 6 and 7 and kept getting a failure at a very specific point in the stream. The failure would result in the rendered file locking on the first or last frame of the entire video. I tried deconvolving to either DV or uncompressed formats, no difference in the failure. BTW, I have the number of threads set to "1".

I finally resorted to trying version 4. To my amazement, version 4 breezed through the entire rendering process withut a hiccup. wutsup Sony? Are u sacrificing conventional processing capability for this new fangled HDV stuff and ignoring what used to be your bread and butter? I recognize that WMV is a delivery format, not meant to be editted, but, if v4 can do it, why can't v6 or 7? I didn't change any of the default settings. Have you changed the defaults in v6 or 7?

deconvolve

Wow, that's a new one! What does deconvolve mean? Is like unencoding?

Jay..

Wikipedia: Deconvolution is a process used to reverse the effects of convolution on recorded data. The concept of deconvolution is widely used in the techniques of signal processing and image processing. Since these techniques are in turn widely used in many scientific and engineering disciplines, deconvolution finds many applications.

IOW...yeppers, un-encoding

This could still be unfixable it the more recent issues are a primarily caused by a Microsoft bug. This type of parting-of-functionality can be influenced by a developer like Sony moving with their upgrades whilst at the same time Microsoft do theirs. So the library-based-handling of WMV media affects many vendors products through poor regression testing.

I'd say to keep both versions of Vegas installed, if this actually also works?

Vegas4.0 can still be downloaded, fwiw:
Current Versions repository

Maybe you can't use a Vegas5,6,7 purchase key with it, I've never tried this though.
Let's hear what Sony have to say. More and more appliances are capturing AV in highly compressed formats. Very remote ENG-crews, HD and solid state recording is only going to bring more of this to our doors. So it isn't quite so unfair to expect these temporal formats to be accessible (even if they are in some way peculiar or have a coding error that could be skipped at worse to the nearest keyframe).

So if this issue can be worked out - it would be good to progress back to what we once had! ;)

Interesting point Rbartlett.
Still, it begs the question of whether chronic annual updates benefit someone like myself who hasn't made the transition to HDV. As long as the updates were in the $150 range, and I lost no functionality, I was OK with updating for improved workflow, functionality and capability. But, if, in fact, I am losing functionality, then I think I will reconsider my commitment to annual updates in favor of sticking with version 4, which in my opinion, was the best version of Vegas ever released.

Rather coincidental correlation with the Sony purchase of Sonic Foundry software. If Sony has its corporate tentacles dictating software development in Madison, this kind of problem will certainly become more prevalent as the pressure to meet corporate schedules takes precedence over reliable programming.
