Video camera - MDA II, XDA II, 2060 General

Hey all
Has anyone done much video recording directly to an SD card? My SD card has a very low write speed so everything is very choppy. Has anyone managed to record perfectly smooth video straight to SD?

My recording is fine, what type of card are you using?
I have a Viking Interworks 256Mb SD from ebuyer.co.uk and it's fine despite being quite cheap!

I bought a 512MB fujifilm a while back real cheap from ebay, i guess it was really designed for photos, write speed i benchmarked was 0.01MB/sec

Same problem here...
Making videos directly to my Sandisk 1gb is very very choppy.

but then sandisk are one of the slowest cards around

The new "I" SD cards.

Did anyone read about these cards, they are supposedly fast enough to record hd video in real time according to a article on engadget. If we could get control of the 720 hd recording on the evo, and increase the frame rate and other things to make it actually GREAT quality with these sd cards.

Problem, doubt the evo has the hardware to use these cards to their full potential
someone did the math before... even with a class 6 sd card you'll be able to get much much better quality 720p video... just need someone to figure out how to change hte compression.
Another problem, how are you going to fit an SD card into a MicroSD slot? Do they even make Micro SDXC's?
I have a class 10 sdcard and i did a speedtest on it using a bemch app on the market. It gave me 3-5MB a sec for write speed... i think htc half assed the hardware interface between the sdcard and the phone :/

[Q] default memory card too slow?

Hey all,
I've had a Streak for about a month now and one major problem the device has had is poor video playback. I've tried Rockplayer, but the results were terrible with very poor sync. I was reading on the Streak Smart forums that this can be caused by the default memory card simply being too slow. I was wondering if anyone here had any experience with this? Can Rockplayer be improved by getting a new memory card?
Josh
I would hazard a guess and state that you are still on Donut v1.6?! If so you most likely won't be able to obtain any improvement, whatever player you try. I had the exact same issue.
It would seem that the streaks can be separated between those who have video issues on donut, and those who don't. I was only able to get relief when I upgraded to Eclair v2.1
If i'm wrong and you're already on v2.1, then only two players have have worked the best (for me) are: Rockplayer & YXplayer.
it may also be dependent on the resolution and bitrate of the videos your trying to play.
hmm. it's definitely worth you posting the specs of the videos you're trying to play.
I've got some h264 mp4 videos with aac (that right?) sound carried over from my Sony X1 (same screen res). They play really well on the stock video player and REALLY well with the build.prop modification.
I converted them from the discs using DVD Fab. File size comes out about 4-500mb. I actually use the video playing to "show off" some of what these phones can do (always turns the iphone users a bit green for some reason... )
the 16GB card that came with mine is Class2. I've tested it with ATTO and it showed around 10MB Read and 3.7MB Write speeds! The Write speed is slow yes but for reading movies I think that 10MB/s is quite enough! Please have in mind that the "Class" marking on the cards is for Write speed! It is not uncommon a Class 2 card to be actually faster than Class 4!

[Q] HTC Desire HD Poor Video recording Quality

Guys can anyone help...
Is it just me or is the video recording dropping frames and jumping...
Why, could this be a buy?
Please help
My SGS is flawless when it comes to recording and pics even with no flash and low megapix

If that happens, you're either running to many other programs at the same time OR (and most likely) your SDHC card is to slow
no frame dropping or jumping here when I record 720P, using the provided 8GB SDHC card

Video stutter

Has anyone had problems like me with video playback being stuttery? If so has anyone found a solution?

There have been a few threads about this, most of them point towards the SD Card.
Try to find a higher class card i.e. Class 4 or 6 and format with a larger data allocation size 32k or so. Seems those work the best.

Any point in higher then class4 sd?

I had my Kingston 8gb class4 micro sd with me since my N1, now with the Gnote I find myself wanting more space.
The local price for micro sd cars ain't cheap, up to 50$ for 32gb class 10, but I can find a cheaper class 4 for the half of it (Toshiba microSD)
any point paying more?

if you are planning to store documents and photos and backups... a class 4 is great.. however if you are planning to run games or play movies or get the camera app to record videos and photos directly on the SD card.. then you will notice a huge difference in your phone speed with a class 10 SDHC or SDXC cards...
Right now I run video files from my current sd card, don't see any problems

would I be able to record 1080 video to a class 6?
I got a sandisk 16GB extreme HD class10, from amazon for 18$. Worth purchasing

I had a 32GB class 6 before buying a faster 64GB card. Handled everything no problem. Full HD MPEG2 (4:2:2 profile) is normally about 24 Mbps (3MB/s) worst case, and MPEG4 should compress way better and therefore have even less chance of performance issues.

no issues runnuing movies from a class 4 card, a class 10 is wasted in a phone, the speed difference wont be noticable, only difference is when copying to usb

^^ which i think many of us do here on xda, transfering 100-600mb roms on the daily
its nice to transfer a file that large in the amount of time a class4 moves a 50mb file
but in the end its user choice on what they want and want to spend, they all work perfectly fine.
it sums to this :
Class4:
SanDisk = 115nis
Toshiba = 110nis
Patriot Signature Line = 125nis
avg of : 116nis
Class10:
Patriot LX Series = 185nis
G.Skill = 170nis
Transcend Ultimate = 190nis
avg of : 181nis
*3.8nis ~ 1$
it sums to 65nis (~17$) difference on avg
also i started to wonder on 16GB much cheaper and i can get higher class with close to nothing money difference
your opinion? what company to choose? and should i go 16GB or 32GB
most 1080p videos are encoded at 16mbps or so.
16mbps / 8 bits in a byte = 2MB/s minimum speed you need to watch/film a HD video.
so a class 4 is fine for watching HD videos.
if you were, say, using a galaxy s3 where they can take photos whilst filming video or can do full 8mp burst shots with up to 99 photos at a time directly onto SDcard, then a class 10 will be more useful as it wont hold back your device.
a full quality 8mp photo on my note takes up to 3mb. so with a class 4 that can handle 4mb/s, in burst mode, you're stuck with about 1.33 photos per second. whereas with a class 10 that can handle 10mb/s, you can do at least 3.33 photos per second.
if you were filming whilst taking photos, a class 4 will only take 1 photo per 1.5 seconds whilst filming 1080p, whereas a class 10 can do 2.66 photos per second whilst filming 1080p.
so on a galaxy note, no real need for anything faster than 4mb/s for most people. but on another device, a class 10 will be more useful.
