Is there a way to convert a video (mpeg, mpg, avi) to another format?
I'm wanting to get it to something like, 80x80 with 4-bit greyscale.
This is the type of format VideoNow uses, and I'm wanting to try and convert some Futurerama video's over to that format and try on the Hasbro VideoNow product.
Just to show you what I'm talking about, here's a picture. I know the video sucks at that format, but it's for my kid. So no big deal.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Go have a look at http://www.slashdot.org
A few days ago, there was an article from someone trying to do exactly that...

Here's a link:

He hasn't posted any thing since Sept 7, so I'm not sure if he's still working on it. I hope he is and finishes this project. -
So do I. A $50 player for little kids sure beats the risk of losing or breaking a $500 portable DVD player.

i've done some reverse engineering on this product. the link above will lead you to my journal on my fansite (for the defunct cybiko handheld computer).
i'll post updates as they occur.
like you, i want to create custom videos for my daughter.

their mobile phones have got better displays than that thing! In fact some watches have better displays than that.
Corned beef is now made to a higher standard than at any time in history.
The electronic components of the power part adopted a lot of Rubycons. -
actually, not.
most mobile phones are monochrome and cost between $250 and $300
the video now has (barely) acceptable resolution for the task at hand.
but i would recommend waiting until after christmas to buy one. i anticipate the price will drop to $25 or less by next summer.-greg

This thing will flop like the little HITCLIPS music did. Within months, they were on clearance for mere pennies.

well all the better for us. that means the market will be flooded with hundreds of these items for pennies per pound. all the more reason to know the file format, so we few can create our own videos-on-the-go.

It would be nice if they did bomb and end up in bargain bins. I could pick up a few and if anything happens to it, I'll just open a new one and burn a new disc. It probably won't get much if at all from a pawn shop.

it turns out the extra media (3.5" instead of 3.25") is just to make the capacity larger - i think they wanted to get up to 30 minutes. it also has the effect of making the disk unplayable in mom or dad's cd player where it would make an unpleasant noise. but i've successfully copied the tracks from the original sampler disk to a 3.25" mini-cdr and it plays. so a 3.25" disk is an option.

there is still a problem of the "key" disk...
it seems that the device samples the innermost track at power-up. i'm guessing its reading the vtoc. when i create my copies the vtoc apparently doesnt have the information the device requires.
my question is - does anyone here know how to read the vtoc or any other information stored in the center hub of a CD?-greg

i authored a videonow cd last night. a 13 minute bugs bunny video.
i will clean up the code and add a gui tonight. then post to sourceforge.net under the project name "VideoThen"-greg
(author of videothen) -
Woo-woo! Now I have no reason not to get it. Beside I believe at one store the Video Now is on sale for a paltry $40.
"VideoThen" is a cute name.
Now to find a way to batch convert 130 Thundercats episodes (22 min each) to VideoNow format. Would I need to convert them all via VituraDUB or can your VideoThen handle the video conversion? -
videothen accepts as input an .avi with 80x80 greyscale and 8-bit audio. so virtualdub does all the hard work.
edit: I have a test version of videothen that runs as a batch but its very raw. i will keep you in mind for version 2 of videothen which will take command-line options to run in batch mode.-greg

Better than nothing. 8) Unless you want to donate a portable DVD player?
FWIW it only takes me 8 minutes to convert a single episode to 80x80 greyscale and each files are under 20MB. Now to get the JAVA converter when it's released... -
i released videothen on sourceforge.net

Coolies! And at a great time too, Toys R Us is having a sale on their VideoNow from now until Nov. 22. $40 for the player and each video is $2 off.
(note to mods: I don't work for Toys R Us and I won't get any benifet for plugging Toys R Us. It's in this month's "Big Book" ads from Toys R Us.) -
I'm running into problem and I'm not sure why. Here's the screenshot of the DOS box with the error messages:
The VideoThen reported unexpected EOF. I've tried a few different video files and it seems to happen everytime during converting to WAV, about 1/4th of the way through. THe rendering process goes without trouble.
Any idea?
I have 2.4GHz P4, 1GB RAM, combined hard drive totaling nearly 500GB (350GB free) and Windows XP home with SP1 pack. -
yes, someone else has a similar problem. try checking the audio sampling rate in virtualdub. make sure it is 44100 hz - some videos use another rate.
-greg
(author of videothen) -
I tried that and had VDub change the audio rate to 44.1K Now VideoThen can last until half way before it stops with an EOF error. I checked back with earlier video, the originsl rate was 22050 Hz
<hypothical mode> Hmmm... I wonder if I somehow get the audio rate to 88.2K, masybe VideoThen would be able to finish the process before getting EOF? </hypothical mode>
I did make sure the audio is set to 8 bit mono and no compression for either audio or video. Video is reduced to 80x80 greyscale.
EDIT: I think I have this solved. I'm not sure why it worked this time but I flipped the order of the video filter in VDub and VideoThen now works without getting an EOF. It seems the filter order may be important.
PS here's a quick trick to loading VideoThen without having to open a DOS box and typing in long command. Go to the folder where VideoThen is stored, create a new text file, put in "java -classpath videothen.jar com.alcorgrp.videothen.VideoThen" (without the wuotes), save it, and then rename the file to VideoThen.bat. Just double-click it and it loads. There are still some uses for the old DOS Batch command... -
sounds like you have it licked.
i apologize for the problems. i have one other "customer" and she had the same issue.
what i may do is "zip" the project up into a zip file and deliver the .bat and .cfg files for the configuration.
have you actually burned a vncd disc yet?-greg
(author of videothen) -
Yes. I burned a sample on a 3" and tried it out. It worked. The filter order should have been greyscale first, and then 80x80 reduction.
Now if only there were some way to get the disc to stop spinning for the swap. Do you plan to try and figure out the "key" in hope the swap wouldn't been neededin hte future? -
I think the key is very simple: you must have a 3.5" disk with exactly 30 minutes of video on it. I believe this because the sampler cd comes with a blank track on the end that fills out the rest of the (unused) disk. if ever we can find a vender selling 3.5" disks then the key issue will be solved.
i dont wait for the disk to slow down. i just stop the key disk with my finger and remove it. then when i put the vncd in i give it a little push to get it started.-greg
