Recording VIDEO directly to SD Card

I have attempted to record video on my XDA II directly to my 512MB SD Card, but the card can't keep up with the video capture.
Does anyone know of a way to speed up the SD card throughput, or ANY way to record the AVI format (which seems to be the highest quality) - directly to the SD card.
What I am doing now is recording to RAM, and transferring later to SD.... very tedious.

What type of SD card are you using?
I just bought Sandisk Ultra - can _really_ see the difference!

Have never really played with it, but recording to AVI makes larger files. You may want to look for the best compression the device can handle in real-time, since this will reduce the throughput needed to the SD.
And yes, get the Sandisk Ultra.

Thanks
I'm using a standard Kington 512Meg card..... I will look into the Ultra.
Any other recommendations - perhaps related to the FAT formatting of the card?......

Storing Photos and Videos on SD

Is there any way to ge tthe camera application to store the pictures and video taken directly onto the SD card instead of internal RAM?

From within the Camera Application click on the "tools" Icon, then click tools (bootom toolbar) and select options from there you have an option to change the folder wher the image is stored....simply select storage card.....or whatever else you deem appropriate. :lol:

Bugger that wa easy; how dim??
However, after some experimentation I have found it is not practical to store video directly to a card - the transfer rate is not fast enough and the video end up jerky.

strange, I wonder if it has anything to do with the type of SD card you are using, I take videos quite regularly at times a good 2-3 minutes in length which I mail to family back home in the UK and I can't say i've exeperienced anything similar to what you mention. I'm using a SanDisk 512 card with the latest ROM release from I-Mate.

My SD is a Kingston 256.
I wonder if it is something to do with the access times of the SD cards??
I know if you spend more you get a card with faster access times.
Or; what resolution are you taking the video clips in? Obviously the larger resolution will require more data throughput and may slow down the 'saving' of data.

Whats stranger: The Kingston 256MB (Toshiba manufactured) are quite good & stable, whereas Sandisk tipically performs worse and is less stable!
So it has to be the resolution used.
I too experience limitations of the datatroughput when capturing video (biggest resolution) directly to SD.
For pictures it is not a problem.

accesstime should be very low on all sd cards not sure if they differ
accesstime is how long the system can get to the data sector it want to read or write
accesstime mean alot more with hd's because they are mechanical
sd and other flash types have very low accesstime
but the read and write thruput differ
you can use pocket mechianics to benchmark and compare with other sd cards in other pda's

I use the large capture size (240x320) i''ve got pocket mechanic on mine so i'll post the benchmark reults when i get a minute

Sandisk are as good as any other, I have been using them now for 1 year in my MDAII and have been operating without any problem, I use them to store Video, photo's and mp3, and change on a daily basis between about 3 different cards (music, video and photo's)

well in the pocketmechanics benchmark sandisk are not as fast as many other brands

Is it really, didn't know that
So which is the fastet 512 SD currently

donno
try looking at the bench's in pocketmechanics
also there looks to be a difference between the
sd speeds of different pda brands
and also i doubt the benchlist in pocket mechanics
is up to date
and then there is the problem with some cards not being compatible
with some pda's
......

all i got is error message when i set it to save directly to sd card
i have lexar 1gb card.
error message is
cannot record the file
36001106:0
fail to ....the film...etc
any idea?

1Gb SD card - does XDA II support it?

Does it?
Thanx

Igb Card Support
Yes I am using a San Disk Igig card for GPS Maps with no problem.

great ! thanx......

...and I use one for movies!

1 gb
i use it for my MP3s and movies as well.

what about high-speed x60 1G SD card ?
faster then normal speed ?

i'm using 1gig 60x pqi sd card. oftentimes it works. problems encountered: xda2 can't detect the sd card. never done the 3x format yet.

you won't see much in terms of speed in PPC. all these fast speed SD is meant for digital camera & video actually.

I have a 1Gig card by 'Integral' that claims to be high speed. I was having some problems running gps mapping etc from it, though for mp3's and videos it was fine.
I have now bought a 512 SanDisk Ultra 2 card and Tom Tom is much better with this card. Using a multiple file read/write test to copy from the card to itself, the new Sandisk card is significantly quicker, and Tom Tom runs/opens much better than it did with the 1Gig card. So higher speed cards do show an improvement, though not as much as when they are in a device that can take full advantage of the card, like a PC card reader for instance.

I have a x66 PQI 1Gb SD card that I run TomTom3, MP3's and store presentations on. I have had no problems with this card at all. The higher speed of the card does make difference and improves the performance to both the applications and the speed at which data is copied to the card (not using hotsync).

Ive found that some really cheap SD cards have loads of problems.
I bought a cheap card and it was terrible, kept not working, corrupting files etc. I swapped for a 1gig Sandisk, all is well, no problems at all.
I found that the 32meg NOKIA cards given with most new nokia phones a year or so ago dont work. They are totally unreliable.
You get what you pay for, the faster cards are normally more expensive, and ive noticed the difference when copying big files from ram to card.
Get the better cards, its worth it in the long run.

What speed SD for the Universal?

I havent looked too deeply into this, preferring to ask like .. So please don't eat me.
Its late and all ..
I'm wondering what speed the SD card reader in the Universal is?
Is it worth spending a little extra on some 60x Corsair SD cards or should I just get the bargain bin stuff since the Universal maybe doesnt have a particularly quick card reader?
Any advice welcome. I plan to use this is a system disk with seperate 512 card for my MP3's and pod casts/documents. THAT will be cheap stuff.
But for the main I need a 1gb system disk for storing apps and system stuff.

Compared to a dedicated USB card reader for the PC, the Universal is extremely slow - I have tested this with my 150X 2GB SD card. So unless you plan on using it with a PC card reader, it doesn't really matter
Accessing the SD card through activesync was at least 10 times slower than the card reader...

I did a small test with Pocket Mechanic.
1. My "normal" 2 GB sandisk gives 0.84MB/sec
2. My super duper Extreme III Sandisk 1 GB gives me a whopping 0.88MB sec.
Nr . 2 card, in my portable, writes files much, much faster than nr.1.
You can see however that in my Jasjar the difference is nearly zero.
I would say: go for the cheapest, but I am not a great technician.

Thanks guys ..
Very informative and will help me get the right card. ie. the cheapest!

Hi
I have not noticed any difference between a basic Sandisk card and a so called 66x KingMax card when used in the exec.
I do notice a difference between these two cards when using them with my digicam - the multishot mode (2 frames/sec) actually works cause the camera is able to write to the card quickly enough. With the slow card, cam kept pausing to write its cache onto the card.
I am not sure that pocket mechanic tells the truth! Likewise, timing a copy from the internal flash to an SD card is not gonna give accurate results (speed of internal flash may be bottleneck). On Wm2003 devices this was possible cause RAM is loads faster than flash still.
You cant test the speed of the SD reader in the exec over activesync tho!! Its a USB 1.1 device (max 11Mbit) and on top of that activesync treats it as a 10Mbit network card. Max you'll see after overheads is thus around 1MByte/sec

Certainly much better to do it that way.

ok i m having problem to decide as well...
anyone has a more concrete data about this ?
i m thinking whether to choose a normal 66x or 133x ...
getting 2gb sd card.. either transcend or pretec...
by the way exec sd slot is 1.01 or 1.1 specification?
hope someone has a benchmark to share.. thanks

1gb Scandisk does the job for me.
Watched a movie on it the other night, perfect. Plenty fast enough.
Its HTC so you can be assured it will be genius design with cheap crap chipset.
Bit like an Italian sportscar.

get one of those sd-usb card combo's....if u can find one going at a decent price.
saves the hassle of card readers. the LAST thing anyone needs is yet another wire lol

Storage Card

I have just purchased a Sanddisk ultra ll 1.0gb storage card.
It works fine in my digital camera but when inserted into my spv m600 the device wont recognise it.
Is there a storage card limitation with the prophet and if so is there a way round it ?

I have similar problem with SD card Transcend 2 Gb x150. When I got 2 Gb TwinMOS x66 problem disappeared. I think the problem is the too high speed of card. Probably they can’t work at speed which is sufficient for Prophet.

Card problem?
Anybody else had sucess with the Transcend 2gb card x150? I was thinking of purchasing the 4gb version, at same speed, but now I'm not sure I want to waste my money.
Anybody else have a 4gig, can you name brand and speed pls?

I have used both the sandisk 1gb ultra II card and the sandisk 2 gb. Both work fine in my I-mate jamin. The ultra II is much faster, but i mostly use the 2gb card, cause I need more space. If they had a 2gb or 4 gb ultra II i would buy it also...I have also used the PNY 2 gb cards. They all work in my jasjar as well. But like i said, the ultra II works best.
You might need to re-format the card and then try it (not with the camera format option, but from the Jamin)
You can download a beta copy of pocket mechanic (good for 15 days without license) at www.antontomov.com go to forum and check pocket mechanic beta forum for latest version

Thanks eagle1
That's good news Eagle. What are the speeds of your two SD cards?
Anybody use a 4 gig non-sandisk card?

I'm using a Trandcend 150xSD 4 GB and it works great.

i am using an sandisk extreme III (150x) 1 GB and works great

Still no card showing
Thanks people for your posts and advice i have tried a few things including pocket mechanic but still have not managed to get my prophet to accept the Sandisk Ultra ll 1.0gb sd card.
If anyone comes up with a soloution or indeed has a SPV M600 with a working Sandisk Ultra ll 1.0gb please let me know.
Just off to e-mail Sandisk to see if they can help.
Thanks again for your posts.

It seems that high speed SD cards workability balanced on the edge with Prophet PDA’s. So best approach would be Try – Before – Buy. “Minor” problem would be to find store where this approach works for SD cards .

Has anyone tried A-Data 4gb 150x?
Has anyone tried A-Data 4gb 150x? I think this is the cheapest 4GB card out there, so I'm wondering if anyone has tried it on the prophet?

I have just started using a 4GB 'Topram 150x'. Seems to work OK, except can't directly save photos to the SD card. According to other posts, something to do with having more than 2GB of empty memory. However, can transfer photos from main memory to the SD card without any problems. Music and videos appear to store and play back without any problems

SD CARD NOW UP FOR SALE
Still no joy with my new sd card so decided to put it on ebay
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7612649443&ssPageName=ADME:L:LCA:UK:11
Had a word with the staff in the local pc world to let me try before i buy but no go, they said they would not give me my money back either unless the card was faulty. Not that i would buy one from there with the price they charge.
Will keep you all posted on what card i get to work with my SPV M600.

I'm confused
I'm really confused. How can it be that a particular Sandisk 150x speed works, and another one doesn't? Or one 4gb high-speed works, the other doesn't? I can't seem to find a pattern here. Its just random.

My guess is the low speed threshold for high speed SD card actually randomly higher than the normal operation for Prophet hardware. In this case two high speed SD cards which are same type of same manufacture may have randomly different low speed threshold, what is out of concerns of manufacturer. Who would cares about low speed access ability? And now we have to go through risk of buying perfectly good SD card which may not work on our Prophet devices. I hate this.

Hi,
I'm using an Extrememory 2 GB and 4 GB SD-Card. No problems with my Jam aka Magician or XDA Neo aka Prophet.

Storage CardJ
Just found this on ebay http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7611242138 works out just under £60 for adata 4gb 200x MMC card which apparently has better compatibility.

I upgraded the ROM and I can now save my photos directly to the SD card as long as the picture resolution is 640 x 480 or less. For the higher resoltion photos I have to save to main memory. Can anyone make any sense of this?
Otherwise I am having no problems with the SD card. I am not about to go and buy another one, so I will just use my workaround of saving no main memory and copying to rthe SD card when memory is low.
