[Bob Flood] “i have tried both straight animation AND “Sheer” rgba and yuva codecs and they dont play in real time either”
Bob,
Without alpha, you shouldn’t have any problem playing SheerVideo tracks at 720p, even off a single SATA drive.
If you’re using an alpha channel, are you using premultiplied alpha (faster) or straight alpha (slower)?
If the alpha is for compositing over another video track, I suspect you’ll have to render in any case.
Were you using the SheerVideo Easy Setups that come with the SheerVideo installer?
Cheers,

[Thundercross] “It also boasts a huge increase in my rendering time”
I hope you meant increase in rendering speed, not time.

[Fongaboo] “I wonder if Sheer might be ideal for VJ’ing where jog-latency is crucial.”
Yes, having video jockeys discover SheerVideo was a pleasant surprise. We’ve sold hundreds of copies to VJs, who value it for the quickest trigger time. They’ve also told us that Sheer’s low CPU overhead lets them apply more layers and effects than with other codecs.

Dave,
Before you call products “stupid” and exhort their users to “forget” them in this forum, I suggest you reread the Creative Cow’s Code of Conduct.
Windows Media and AVI codecs are in no way more “standard” than QuickTime codecs. In fact, until Flip4Mac came out, QuickTime formats were clearly more standard in the sense that they alone were available cross-platform. Even now, QuickTime remains more standard in the sense that readers are available for free on both platforms. Moreover, AVI itself historically derives from QuickTime for Windows.
It’s simply not true that using Windows Media or AVI codecs lets everyone see your files. On the Mac, the only people who will be able to see them are those who buy the Flip4Mac reader, which is not free. In contrast, if you use SheerVideo, everyone on either platform can see them, because the SheerVideo Reader is free on both platforms.
We believe that both QuickTime and Video for Windows are standards worth addressing, and for those who prefer the latter, we plan to release SheerVideo AVI later this month.
I’d like to know in what sense you feel that the SheerVideo Reader is “stupid” or “special”, as opposed to the decompressors that come with Flip4Mac. It’s free. It works. It’s readily available. Hundreds of thousands of people have downloaded it. If you would like to see the product improved, please let us know, rather than publicly dissing it.
Also, it’s not true that the Flip4Mac Studio Pro HD ($179) costs the same as SheerVideo Pro HD ($149).
Finally, the SheerVideo family of codecs offers features that no other set of codecs provides. No other codec, whether QT or AVI, offers real-time lossless compression and decompression of both RGB[A] and Y’CbCr[A], both 10-bit and 8-bit, both Y’CbCr[A] 4:4:4[:4] and Y’CbCr[A] 4:2:2[:4], or optional alpha in all codecs. And no other product anywhere offers lossless interconversion between RGB[A] and Y’CbCr[A].

This was a known problem with Final Cut Pro 5.1.2 and QuickTime 7.1.2, due to a hardwired limit in the number (64) of codecs they could handle. This problem had nothing directly to do with SheerVideo, but because SheerVideo Pro itself contains 8 encoders, 8 decoders, and 5 transcoders, it often showed up when installing SheerVideo. Fortunately, this bug was fixed in Final Cut Pro 5.1.4 and QuickTime 7.1.5.

No, BitJazz is definitely not out of business. I apologize for the brief disappearance of our website. We had just finished a complete redesign of our website and switched to a new webhost to provide the expanded services we needed, when the new webhost was sold to a company that outsourced all technical support to an inexperienced offshore company that failed to get our website up, so we had to scramble to find another new webhost, and were offline for a few days.
Since then, we have launched the Mac Intel and Mac Universal Binary editions of SheerVideo, as well as number of minor releases, and are close to launching SheerVideo AVI for Windows PC.

BitJazz is emphatically not out of business! In the middle of redesigning our website, our new webhost got sold to a company that outsourced all its tech support to a team that lacked the experience to deliver the services we needed, so we were offline for a few days while we scrambled to find another new webhost.
In the last few months, in addition to completely redesigning our website, we’ve issued a number of new releases of SheerVideo, including launching the SheerVideo for Mac Intel and SheerVideo for Mac Universal Binary editions.

FireWire 800 is supposed to be able to deliver a sustained throughput of 85 MB/s, and reportedly does so on many PCs. However, Mac G5 users have reported hitting ceilings of around 50 MB/s for writing and 70 MB/s for reading, whether using the built-in FireWire 800 port or a PCI card, even for RAID 0. However, I’ve read a couple reports of getting over 100 MB/s on a RAID 0 array in which one disk uses the built-in FireWire 800 port and the other uses an add-on FireWire 800 port, even with several other devices chained onto each of those FireWire channels (https://www.it-enquirer.com/main/ite/more/firewire_800_power_mac_g5/).
