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?

Camera

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?

[Q] Youtube on HD2

I have a problem playing youtube videos on HQ on my HTC HD2 Pdaimatejam. When i play video it doesn`t go smooth,plays for 3-4sec. then freeze for one sec. (meanwhile the music goes).Please help me,i really like how windows 7.8 works on my phone.Thank you

maybe your SDcard is slow... SD card is used as phone memory and if working slow can cause problems with video and sound....
download WP Bench from store and test storage memory speed....

Speed results
CPU: seq 3.68^5 L/s par:4.05^5 L/s time: 20721ms
Data: mem 15.14 MB/s stor 5.6 MB/s time 30634ms
GPU: 530 frames, avg:15 F/s
whether these results are good? I have MicroSD class 10 inisde.I tried all youtube apps. non of them work well

important is storage speed... no mater which app you use if memory cant go faster... also if you put more data in memory card work slower and slower... also with dual boot, card work much slower....
i have Sandisk class2 32GB card and on my (or not my because sold it ) storage speed was around 8-9 MB/s and dont have any problems with videos...
in most cases, SDcards with lower class (class 2 and 4) work better and faster than higher class cards... people think higher class work faster but in reality higher class not very supported in WP7....
also you can try flash other version of this ROM or ROM from other developer and test how your SDcard work with this ROM... maybe you find one which work better with your SDcard

DVR camera showing but not recording

Hi all;
I have an android multimedia HU on my car. It is sold under the brand Navimex .
It has an 8" display, running on android 7.1.2 . Cpu is Cortex A9 ( PX3 ) . 2 GB DDR3 RAM and 16 GB memory.
Although there is DVR support , I couldnt manage to record road videos by DVR.
I have two DVR cameras.
One is with SD card slot and it works with its own USB DVR car apk. I tried it on other cars' android systems it worked well . But in my car's HU no video and no recording
Second is without SD card slot. It shows the road ahead live but never records it.
it shows but does not record. There is enough free space on flash memory, on USB 2 device, or putting a 4 GB SD card as an SD card or GPS card. Either way it doesnt record
Can anybody help me? How can it record videos ?
PS: As a beginner, Im not allowed to post links of the cameras and HU , even the youtube videos

Did you solved the issue with the dvr usb camera? I have the same issue.
