HD DVD gets 1080p 24fps output thread.

All the owners of reader HD-DVD l´attendaient, it arrives finally, the update allowing platinums of living room to leave a signal in 24p. For recall, the films in HD-DVD as well qu´en Blu-Ray are encodés of 24 images per seconds (24p) but leave the readers into 60 Hz for a d´affichage question of the no-claims bonus (which them are in 60 Hz). The fact d´afficher of the 24 images per seconds in 60 Hz causes what l´on calls an effect of judder which makes the fluidity much worse than of the Stake or the original 24p. The update should be available towards the end of this month, for the happiness of all the compatible owners of diffusers 24p which will profit then d´un perfect marriage.

Has anyone tried this??

How does that site confirm 24p output?

For example the use of 5:5 pull down, other frame rate conversion techniques and further if the signal employs frame insertion technology and more...

So the floor is open to ask questions about how A20's and XA2's successfully interpret the native disc video quality and exacting spec's and their importance.

BTW, here's a French article about Toshiba's 24 Hz firmware upgrade

Finally, is the A2 left out of this upgrade?

Thanks!

Steve, from what I have been told The A20 and XA2 will pass the native 1080 p 24fps directly off the disc and out the HDMI. Since the firmware will permit 24fps and or 60fps.

When playing a native 24fps disc to get to 60fps (for PIP and other HDi applications) the player will do a frame rate conversion of the 60fps PIP video to 24fps to match the refresh rate of the 24fps film. The player will have no trouble handling either frame rate internally and the player's entire output will be either 24fps (or 60fps for native video discs) so displays will not have any trouble syncing.

No interlacing or de-interlacing processing will occur. When the user selects PIP the player will take the 60fps video and do a frame rate conversion to 24fps. Toshiba understands that the PIP video conversion may slightly effect the PIP image quality, but considering the available options it seems to be an excellent choice.

This information may not be 100% accurate as it's what I remember from my conversation a few months ago when I was discussing the process of 24 Hz upgrade with one of my most respected contacts, Toshiba's senior manager of HD DVD software development.

So this would mean that within the next 30 days, we should be able to have judder-free HD DVD film reproduction when coupling an XA2 with a JVC RS-1.....?

Of course, the $64,000 questions is: Why would this have first been announced on a French website......? What is the real confidence level surrounding the release date?

A word of caution here. I suggest those that are anticipating this feature that have not yet either seen 1080/24p or compared it to 1080/60p try to temper your enthusiasm. I have a Sony Pearl projector which, for those that don't know, not only accepts a 24Hz signal, but also refreshes at an even multiple of 24, in this case 96Hz, which is necessary to exact any benefit from 24Hz output. I have also had a Pioneer, a Sony, and most recently, the LG combo hooked up to the Pearl to test and evaluate 24Hz playback. In the case of the LG, I have tested 24Hz with both Blu-ray and HD DVD.

My opinion of this feature is that it is only marginally beneficial. While 24Hz playback from HD DVD and Blu-ray is very slightly smoother than, for instance, 1080/60p from the XA2, it is a subtle difference at best, and can only be noticed on particular camera motion (slow horizontal pans). Much of the time, there is no visible difference at all. The important point to remember is 24 fps does NOT provide perfectly smooth pans, no matter what the refresh rate. It just isn't a high enough frame rate for that.

This is not to say I don't welcome Toshiba working to offer this feature to HD DVD owners. Every bit of image quality improvement should be the design goal of both formats. More and more displays are being designed to take advantage of 24Hz playback, so it will become a more important selling feature for HD DVD. However, folks should understand that the actually visible improvement is not that great.
