The VRX is a device that records videos straight to the Sony PSP Mpeg-4 (MP4) format right to Memory Stick PRO Duo cards. There are two encoding levels: 320x240 and 210x145, both at 15fps (frames per second).
• Video CODEC MPEG4
• Audio CODEC G.726/AMR/AAC
• File format MP4/ASF/3GPP/ 3GPP2
• Memory slot Memory Stick/SD Card
• Input: 3.5mm 3-pin connector, (Composite & Audio L/R + earth)
• Recording mode: Super Fine/Fine/Normal (Frame Rate 30fps / 15fps & Screen size)
• Screen size QVGA(320x240dot),QCIF(176x144dot)
• Memory card: SD, MS, MS PRO Duo
• Auto recording using VCR timer
• VFD display: PLAY/REC/STOP/MODE. Also, amount of time remaining on memory card

The device would be great if it could schedul recodings of all your tv shows directly to memory stick w/o a computer hookup.

if this thing had 29fps or higher then i would really want to get this baby but i think 15fps is kinda choppy.
+
It is choppy, but I wonder how much of that has to do with optimizing the video for viewing on PSP? Will the 14 lost frames / second be that noticeable?
+
Aren't cartoons under 15fps? If so, then this would be perfect!
+
why pay when you can get psp video 9 or 3gp converter for free
+
most cartoons are probably made with 25 or 30 frames per second, 15 fps is pretty low, if the device blurred the 15 fps it could make a video that looked almost as good as a 30fps video, but I doubt it does that.
+
lol allllll video is done at 29.97 frames per second
If you loose any frames it is noticable next to the original.
I have some of my student films on my psp compressed to 25 frames per second and they are VERY choppy to me
The way cartoons are made is they will create actually 15 cells/frames or 10 or 20 then shoot them multiple times so that it runs at a normal speed and its not super fast.
15fps SUCKS big time even if blured it woudl look crappy adn nothign like 30fps because there would be so much bluring that it woudl just look like a slideshow where the pictures dissolv on to eachother and changes really quickly.

To correct and add to FilmGeek's assessment:
NTSC video spec if 29.97fps. PAL (Used in Europe, Oceana, parts of Asia, South America, and Africa) is 25 FPS, and they each have different resolutions and framerates based primarily on the needs of ability to broadcast over the distances common in the countries in which the technologies were invented.
If you're in the U.S., you use NTSC, which is 29.97fps. This is an interlaced format, which means that in each of those frames, you have a subframe where only odd lines or even lines are shown, so you really have 60 half-frames per second, and not 29.97. When you go to the movies, you're watching 24 fps, and since it's film, it is not interlaced, but a full frame (when this is accomplished with video equipment, it's referred to as 24p, p = progressive).
NTSC is very close to the human eye, which is why television looks very different from watching movies at the theater. 24fps is certainly enough to convey full motion, but has a slightly ethereal quality to it that is noticable more on the subconcious than anywhere else, but tends to add to the dramatic value. 15fps is considered the absolute lowest at which the eye perceives objects as being in motion as opposed to being still images presented in series. That makes it passable as "video", though it's hardly attractive, or what the eye is used to seeing.
Anime is traditionally drawn at 10-15 cells per second, and primarily because those shows are done as long series with episodes coming out at a ridiculous frequency. They simply don't have time to do all of the episodes without cutting corners on drawing cells and doing a lot of puppet-esque animation where a still image is drawn once, and simply moved over a background (or vice-versa) on a separate cell. One single drawing can then be used for many seconds of animation, cutting what would otherwise be 40-50 cells down to one.
Cartoons made for film print are most definitely drawn at 24 cells per second to simplify the transfer process, and this applies to Anime, Disney, and 3-D animation films.
IOW: 15fps is pretty crappy all around, and barely passable by the eye as moving objects.
FilmGeek: The PSP doesn't support 25fps, so it's playing 25fps at a regular 29.97 framerate, which is going to look crappy, and throw your audio out of sync within the first second. I can't imagine why you'd choose 25fps anyway. Film is done at 24p. Your best best for "film look" is to do a 3:2 pulldown with frame interpolation at 24p, drop it into a 29.97 timeline, render/output it, and then convert it to standard video for PSP.
If you are using widescreen aspect ratios, check out my walkthrough on getting the PSP to play these natively instead of forcing you to 320x240.

Most likely the reasn it can only do such a low frame rate is that it cant encode realtime any faster then that. Seems like a waste of money, get a video input card if you must.
+
indeed or you can just download what you want you can find anythign online now a days
+
15 Frames per second is just not worth it. If anyone of you have not seen a 15fps movie, just quickly find a short clip on the net and convert it to 15fps, and you will see it just feels not watchable. I know different people have different tolerance levels, but for me 20 fps is the bare minimum.
+
is this device mobile or does it need to hook up to a computer? if the upped the frame rate and create scheduled recodings without computer hookup, like pspczy said, i'd be interested. maybe version 2. i wonder how much?edited: Apr 25 2005

Sounds like it's unanimous that nobody likes the 15 fps frame rate. I agree, but I'd also choose not to buy it simply because it doesn't support wide screen format. I don't understand how such an underpowered device could be introduced in this day and age.
+
It's a handy looking gadget...........if it's under something like $40. Otherwise, just get a TV card, rip your own DVDs, and encode it yourself - this device is a one-trick pony, and somehow I wonder how well it can even do its one trick. Considering that encoded video can come in a variety of forms and bitrates, it's better to use software to encode it according to _your_ needs, towards quality or space as you see fit.
