Relative dithering seems to be the best one, but absolute dithering also pretty decent.

I had a feeling dithering would make the whole video look better by making each individual frame look better, and it looks like that might be the case!

That's right, I'm keeping with tradition of names by using Tru, but I'm also breaking the mold by making a 6 letter app name.

zStart also has six.

I think this video should sum it up.

I still can't believe it... That's a real calculator, with a real LCD showing a real video, while playing sound in perfect time out of the link port? What have you done?

I think one of the humorous parts of this is the insane data rate. The video runs at 10 fps, 10 * 768 * 2 = 15,360 Bytes/s. The sound runs between 17,500 Bytes/s and 20,000 Bytes/s. So that's a total of 34KB/s. That means it burns through Mirage in .5 sec! At this rate, the 84+SE can hold about 45 seconds and the 84+BE can hold around 15. But hey, this is full video on the calculator.

Or a fifth of a rickroll

And you know, since it's me, perfect grayscale. It's not adjustable yet, but it will be.

Again, wow.

In my current setup, I have video and audio looping independently, in the numa numa, assuming you are using the right processor speed, the video and sound are supposed to be the same length, however, the sound ends up being slightly longer since you can't interrupt instructions (which also causes the white noise.) But, I might be able to adjust for that. I could make them loop together, but I'm setting up for Nyan Cat

Oh crap... And disable keypresses so the user can't get out, then make zStart it so it starts up again after the user pulls a battery

EDIT: Absolute dithering. That way it doesn't look weird if the video jumps from a dark scene to a bright light.

This is amazing! I'm sure the dithering will look better on a real calc.

Also, bonus points for emailing me the app and the video early

Personally, I think the dithered video, although noisy, looks far better than the undithered video. In most cases, I don't see why anyone would be viewing their calculator from less than about a foot away, so the noise from the dithering shouldn't be too prominent. And I'm not really sure if ordered dithering would make things better or worse, though. It would result in less noise, but it might also look strange to apply to a video, as I imagine it would appear as if the objects in the video are actually moving under the dithering, not moving with it.

Wow, the dithering makes it look even better!  I wonder if ordered dithering would lessen the static or add the a crosshatch artifact.  Either way, the project is making great progress! 

I can't lower the sound quality, it's already as low as I can make it. I would have two options for lowering the sound rate, slow down my interrupts, or half the data rate by changing bytes every other interrupt.

If I slow down my interrupts, that means that you are going to hear a high pitch sound when you listen to the videos. Imagine what it sounds like in wabbitemu, except it's real.

If I half the data rate, (I can't reduce it in any way but half), you would have a sample rate of 9Khz, which is just unheard of. I don't know how that would sound, but it wouldn't sound good. I would imagine that high pitch noises would get clipped.


I'll make dithering an option unless I find something that really works, which I might.
