Looks good and sounds good too (I can actually hear slight warmth in the guitar!! (If it looks and sounds THIS GOOD over a digital feed,IT MUST BE EXCELLENT IN PERSON!! (Like i have heard))
WMV can look flawless. There is variety of factors involved with how the final product looks. Firstly the source, minor tweaking aside it can't get any better than the source and judging by the video it would appear to be a decent source. They have the camera mounted on a tripod and that is a huge plus as well.
The second factor is what is being used to convert from analog to digital, for example if you use a DV converter you have a very lightly compressed digital video very suitable for recompressing into WMV. If you're using a DVD player or other MPEG converter that's where it starts to go downhill. The captured video may look fine on a TV but for use as source for conversion to an even more compressed format is more likely to produce artifacting that is present in the video. This is point at which most people make the mistake and why so many youtube videos look like crap. You always want to work with the most original source of the highest quality possible.
You don't don't do something like this:
Source>> High quality WMV >> Low Quality WMV
What you do is:
Source>> High quality WMV
Source>> Low Quality WMV
Here is an example of what I mean, the bitrates for these videos were purposely set way too low to illustrate the issue. This first screenshot is from a video that went through one conversion. The source is a high quality DV video and it went through one conversion directly to MPEG2 @ 3000kbps. As you can see we have macroblocks in the lights, these lights are flashing and moving fast so it will bring out the issues associated with compressed video. These blocks are to be expected because of the low bitrate.
When you introduce an intermediate conversion this macroblocking becomes a lot worse. Thsi video went from the original DV source >> MPEG2 @ 8000kbps >> MPEG2 @ 3000kbps. It's only a single intermediate conversion but the results are quite dramatic in how far the video degrades compared to the one above with the single conversion.
Last but not least is the bitrate, you either have enough or don't. It's a compromise between quality and file size especially with video intended to be viewed over the web.

Copying VHS to Beta overrode Macrovision copy-protected tapes as long as it stayed and was played via the Beta format. Copying back to VHS made it visible again when the latter machine was connected to a Tv/monitor though.

Macrovision is actually an error in the video stream that exploited the limitations of early VHS recorders, this doesn't affect playback but does affect recording. It's mandated that new recorders be able to see this error, for example a DVD recorder.
If that is the case with the Betamax those recorders must not be prone to the error and would have been built before the mandate was in place. It would be recording the error though. When played back to a VHS deck or any other device it's going to be affected.
MACROVISION is where they remove the SYNC and it makes the video look like crap!!
Thats interesting though copying to a BETA machine reset the SYNC.. (The BETA player must automatically set the sync right regardless of how it comes in)
The NTSC video standard (the broadcast standard used in North America and Japan) is defined with a 525-line vertical resolution. However, only 480 of those lines are used for transmitting video information. The extra 45 lines are used to carry control codes (such as interlace information), closed captions, and other similar non-video content. Macrovision copy protection works by adding certain codes to these control lines that are interpreted by an Automatic Gain Control chip in a VCR to scramble the video signal if the video is being recorded. Videocassettes that are copied from Macrovision-encoded source material will frequently exhibit color loss, image tearing, variable brightness, and picture instability. Since TVs and video switch boxes do not have Automatic Gain Control circuitry, the Macrovision signals are ignored when the DVD player is connected directly to the television, or indirectly through an A/V switching receiver or switchbox.
However, for this technology to work, the VCR that is used to make an unauthorized copy must contain the Automatic Gain Control circuitry, or no picture distortion will be witnessed. Macrovision estimates that 85% of the VCRs currently in use have automatic gain control circuitry in them, providing copy protection for nearly 550,000,000 videocassettes every year.
Modern equipment like DVD recorder or a capture card on computer wouldn't be affected by this either accept they build it into the software. The big issue there is you can have home movies that may have a lot or errors and some devices are prone to seeing theses errors as copy protection.
??? your point is? , Betamax was Sony's failed competitor against VHS although it did have better quality.
Having said that this is all stepped over especially the video.... You think this looks good?
Sony was in it for the long haul thou. What killed the betamax was no other company making a beta player. Sony did win by hitting the ground running with CD's first establishing a ground work.
The Sony BluRay won I believe only because it was included in the PlayStation platform getting it in to millions of homes.
Sony does drop the ball more than it should. We had the Clie, a hand held like pocket organizer that could go online. Sony dropped the whole platform like a hot potato. The smart phone would have rendered it obsolete so they must have seen that coming.
It's not resetting anything, it's just not affected by the error.
Its not an error..... THE SYNC IS REMOVED so if you try and record it ON ANOTHER VCR,it will not look good!!
