My latest Prop Vid

Hi All,
Here's my latest Vid, of what the prop can do, when not using waitvid for pixel generation.
http://www.jimbagley.co.uk/propavi.avi
It's just using 1 prop ( V1 lol not·V2 Bob·
) it's also only using 5 cogs, ( 1 for TV driver, 2 to feed the driver, 1 for SD, and 1 for the spin demo controlling it all. ) so I could therefore also add sound quite easily, since I have memory left (802 longs.) and spare pins 
Not quite as impressive as BTX's BIG curtain, but equally as impressive as it's only using one prop. Kudos to you BTX, as your curtain looks great, mine only outputs to tv.
I've also fattened up the pixels to pad the screen out a bit, as the lack of RAM only permits a small display [noparse]:)[/noparse]

What's the final resolution/color depth?
edit: The Colour Depth is 15Bit·5R 5G 5B·to give usual 4 pins for programming·+ 4 for SD + 8 for comms, for when I connect it to the hybrid, ( it'll be an add on for the Hybrid ) [noparse]:)[/noparse]
edit: oh and res is 120x90 RAM limitations scaled up to 240x180. although when I do a tilemap + sprites version, it'll be higher obviously.

NEXT UBER vid, ( sorry it's a 3gp from my phone cam, but the batteries went flat during taking the next vid, lol, will re-charge em and do new vid, but for now, here's a 3gp version. )
I have the original on dvd, and was wanting to see how it would convert, so I got this intro vid off the net, to convert that, with it being smaller, and well, the results show how impressive it really is.

Although I'll convert it to use an AD723/4/5 for US side, as it's gonna be an add on board for the hybrid. [noparse]:)[/noparse]
Are you playing back avi files through the prop?
If so, it is quite impressive.

How much different is SCART from VGA?
Forest: Thanks [noparse]:)[/noparse]
rjo_: rofl
Oldbitcollector: yeah, I'll prolly release specs once hybrid and the addon is out.
Dennis Ferron: Thanks matey [noparse]:)[/noparse] SCART is TV timing, ( 64us PAL 62.5us NTSC ( or whatever NTSC is, not really done much NTSC ) and VGA is a lot faster.

It so impressive as my curtain, or more, mine uses about 5200 IC's to do all, you get it with only one prop and a eeprom !!. [noparse]:)[/noparse])
Great !!

What format did you convert them to?
I played with high resolution playback on a 3840x1024 screen 8 years ago. I had 8 195MHz Mips R10000 64bit processors, 1GB Memory and 8 hard drives to play with.
Yours, though quit a bit smaller is quite impressive as your resources are way less. I guess that is the power of getting right down to the hardware level.
Kudos,
Doug
hinv: Hi Doug, I converted them down to a simple form, knowing that I only have a small amount of ram, I have to limit resolution to what fits, also, knowing that it HAD to be double buffered to avoid tearing, because I can only read about 6K per 50hz frame, and each image is 12K. Which works perfect since it takes two 25hz to read a frame [noparse]:)[/noparse]. It's converted into a 256colour per frame not constant colours though, they change each image. it was then a case of exporting each frame to a BMP, then resizing the BMP's to 120x90x8bit keeping the 4:3 aspect ratio, then merging them all into one 12MB file, stripping bmp headers etc. I originally thought about using compression on it, but then I thought, NO, I want lossless, because of the low resolution. And the finished result, looks really good [noparse]:)[/noparse] I'm well pleased with it.
Cheers,
Baggers.
Still, this is very very well done!! [noparse]:o[/noparse]
P.S Is there some way you can use more than one pin out of one pin? like a Y-wire to allow connection to 8 pin devices with your limit of 4 pins due to the others being used?

I would suggest lossles Run length encoding. This should work real well with cartoons like dlair. You could theoretically use 2 of the cogs to do the rle decoding on the fly. This would lower your bandwidth requirements on the input, and therefor may be able to buy you more resolution on the output and still do the same frame rate.
http://en.wikipedia.org/wiki/Run_length_encoding in case you aren't formilliar with it.
as for more than one pin out of one pin, you mean like the joypads only using 4021's? yes you can do that. ps, I have 8 pins spare.
hinv: I thought of RLE, but the images for DLair isn't really flat enough, and has lots of colours, and especially with the already lowered resolution antialiasing the image, it wouldn't really have made that much of a saving. but if you recall my other vid, the oxygene demo, which had a resolution of 240x160 which would have needed a screen buffer of 38400 bytes, was also double buffered, which would have needed 76800 bytes, which is far above the prop's ram size, that one was RLE, and the video driver uncompressed it on the fly, it only took one cog to handle the display and decoding. [noparse]:)[/noparse]
P.S funny, the prop would do quite well as a cellphone video displaying unit. lol but maybe not as well with all those giant resistors.

Please point me to the oxygen demo.
Thanks,

yes the prop one truly is amazing, what it can do, and how much freedom it gives the coder over other lesser mortal microcontrollers. [noparse]:)[/noparse] and who knows what wonderments the prop2 will enlighten us with, I for one can't wait, but unfortunately like the rest of us, will wait [noparse]:)[/noparse]
as for releasing stuff for the avi scalers, and converters, the scaler is a bought utility, there may be free avi resizers on the net, I may release source a bit later when I sort out a free alternative path to the create the vids for prop, once I convert them to whatever size I need, and uncompressed avi, I then run it through a converter program that I wrote, which converts it into a more prop friendly format [noparse]:)[/noparse].

I am very impressed (as always!), it would appear that the Prop community is very lucky to have someone as adept at coding as you. (No offence to the other coders here too!)
Congrats on a job very well done, I can't wait to see what you will do when you finally put all these 'Tech Demos' together!!

Thx, glad you liked it [noparse]:)[/noparse]
Don't worry, I have something cool planned for this one [noparse]:)[/noparse] just hope I can pull it off [noparse]:)[/noparse] as well as my own playable of DLair, but unfortunately, I won't be able to release that one, for obvious reasons.

Lunch cures all problems! have you had lunch?
ImageJ: Just tried ImageJ also, but it doesn't seem to load avi's?, then I downloaded the avi_reader, and it only seems to load one image, and ideas?
