Hello,
When i'm making videos with the camera, and the destination (save folder) is set to the device, the video quality/speed is fine.
But when I set the destination to the SD card, the movie files get laggy when filming fast moving objects or when I quickly move the camera around to film things...
The moviefiles are recorded laggy...
Is there anything I can do to make viderecording to SD card not so laggy? Saving to the device storage works fine, but is limited in storagespace...
Thanks
Could be that you need a higher class of memory card to allow the data to be written to the card at higher speed........
exactly as conan said, depending on the quality of your microsd card the device will be able to write on it only some number of MBs of video to it, if that's lower than the bitrate it won't be able to keep up.
To test it, see what's the write speed on that microsd using a cardreader connected to your pc, a good value should be at least 3MB/s
I have an 8GB HC Class 4 SD Card.
Shouldn't that be sufficiant for normal viderecording?

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?......
What's the maximum transfer rate of the MDAII's SD interface?
don't know well..but it is slower than many SD-Cards..
try to check with Benchmark onto PocketMechanic.
So the xdaII can not take advantage of the new fast SD cards? I mean, would it be useless to by a x60 card?
pretty much unless you of cause had a sdcard reader on the pc which could then when you wanted to bring music or what ever to the sdcard for using for the xda2 it would get copy'd faster
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?
Does it?
Thanx

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.
Hi,
Touch HD have limited speed on microSD card?
I have 8GB Class4 card and i want to buy Class10, i will see any performance increase?
Regards
about the general speeds, those classes express, you can have a look at my unfinished (blueangel) accessories faq here: http://forum.xda-developers.com/showthread.php?t=793862
the speed of the card will be 80Mbit/s instead of 32 MBit/s.
it will not generally improve the speed of your device, since of course, the OS is not on the sd card, but it might access the sd card at a lot of points and slow down slightly, like when you go to the music or photos and videos tab in manila, the card is read for content. apps installed to the sd card might start and run a little faster, and if you have shortcuts to those apps in start menu or as quicklinks, their earlier and faster availability might speed up the phone a little as well.
but this is all about response time, i highly doubt that you have problems listening to music or watching videos from a class4 card, because the possible data rates of music or videos is easily covered with 32MBit/s.
