I'm waiting for my 16gb to arrive but I'm wondering if the chippy video is due to the included memory card.

just got my new 16gb class 4 card and the video steal seems to be a problem. when moving the camera, the video will be smooth, then pause for a split second and continue w/smooth recording again, then the video will pause for a second again and so on. anyone having this issue while recording in hd?

Bumping this thread because both my wife and I have the same problem with hesitations in video. She's stock; I have a 16gb class 4, stock rom, and faux's latest kernel.
Anyone else have or solve this problem?
I also have this problem. I was wondering if it was the sd card. I have this isssue with all sense ROMs. I even unrooted and flashed PD15IMG to get back to "as new" and reformatted sd card. The hesitation was still there. I haven't always had this problem with HD videos... I have a few videos recorded a while ago that are perfect or have one spot where it skips. I have contacted Tmobile about the issue because I have the insurance. The technician wanted to do some research on the issue and get back to me within 72 hours... which should be tomorrow (3-15-11). He said he wanted to see if there was a solution he didn't know of before they replace the phone. I'll let you know what happens.
T-mobile told me it was my sd card. I bought a class 10 and still had the problem. I called them back and asked for a replacement phone. My replacement should be here tomorrow.

Seems unlikely, but keep us posted...
I read that rebooting right before creating a video helps, and I've also played around a little with overclocking the cpu before making a vid. Seems like these have helped on mine, but haven't had a chance to really test it out thoroughly.
I did get good 720p recording a day or two ago. It was a 40 second video with no choppiness. It's the first good video I had in a long time. I was running the RoyalGlacier 1.2 ROM. Team Royal makes great ROMs, especially coupled with faux123's kernels.
Here's some info that might be helpful to someone. I'd been having problems with choppy video, and was using a 16gb Patriot class 4 card. It turns out that this card was at least part of the problem. It's not a 'counterfeit' and was bought through a reputable retailer, and it passed the the 'h2testw' program in terms of overall capacity. BUT, the test showed that the write speed was actually a bit slower than the 8gb card that came with the phone (the read speed on the 16gb was a bit higher than the 8gb card, but I imagine this doesn't matter in recording vids much).
So I'm back to using the 8gb card that came with the phone. This fixes 90% of the choppiness issue that I've been experiencing the past couple months (got the new card in January). Btw, I did try reformatting the card, etc. I'm now going to look at buying another 16gb or 32gb card, but will be staying away from the Patriot brand and also trying to get one that is class 6 or higher.
I have class 2, 4, 6, and 10 cards. Only my class 10 patriot 8gb micro sd card seemed to work. Honestly a class 4 card should be fine for 720p recordings...but something's up with the software.

It may be that something in the software keeps it from writing efficiently, but definitely weird that the 16gb class 4 patriot tested out with a lower write speed than the 8gb one that came with the phone...and that's the only thing that seemed different with that card that would explain why I was getting so much more stuttering on my vids.

what class is the 8gb card that came with your phone? some came with class 2 and some with class 4.
it's commonly known in the storage/memory world that the larger the card size the slower the write (and often read) speeds will be. Granted when an SD card is certified to be a certain class it should meet the standards of that class. That being said, how a card is formatted, handled, and ejected or not ejected properly affects the performance of the card.
in my years of experience buy the size of the card that you need to use...getting a card 2x than your storage needs maybe thinking ahead but if speed is what you want, smaller is better and of course the higher class the better.
I got my 8gb class10 patriot from amazon for $25 flat and have no complaints. SD card tester programs tell me the card is writing data at about 10mb/sec which is what it should be doing.
good luck with your video issues, and hopefully a future update will rectify the situation so that even class 2 can handle the recording and playback of recorded videos on the device.

The card that came with the phone is a class 2, and the test showed it was writing at above 5MBps, while the 16gb Patriot class 4 was just above 4MBps.
In terms of creating videos on each card, I tested them each immediately after a full format and with a somewhat controlled view of the same scene. Thus, the only variable that would seem to be able to account for the poor performance using the 16gb card seems to be the card itself, and, my guess is more specifically, the write speed.
Perhaps slightly over 4MBps is just below the threshold for what is required for a stutter-free video, and perhaps some variability in the cards that shipped with the phones accounts for why some people are reporting hesitations in their videos while others are not.

that's probably a good evaluation of the situation. i never did test my 4gb class 6 card, but i do know it transfered the contents of my music folder significantly faster than the 8gb class2 card that came with the device. Yet that card was still not enough for stutter free 720p recording. I can only assume its speeds were <10mb/sec. So the sweet spot is probably 6mb/sec.+
thinking bigger picture, there's a serious QC issue if some people with the same cards have issues while others don't. though i question if some people think that they're recording 720 by default and never bothered to check the video settings to begin with (default is 480p). therefore some people think they have no problems, but it's only because they're recording in 480p (which is still clear, especially on screen).
i had a few minutes. ran a test on 3 cards
1. 8gb class2 - stock card - ~4mb write
2. 4gb class6 - ~6mb write
3. 8gb class10 - ~10mb write
So as i stated before, for my phone, i need more than 6mb/sec + card for stable 720p video recording.
I haven't checked this thread in a while, but I just got a replacement mt4g w/the good screen and thought maybe it'd improve, but hd video recording is still freezing up every so often. so I've just resorted to taking video in widescreen. hopefully someone figures something out. I'm running faux kernel, stock rom.
So I was reading this thread and remembered a thread I read yesterday in the android apps and development forum. Apparently we are governed by how fast our SD Cards are read, but you can change it. Anyway, if someone wants to try the fix out (seems simple) I think it would be a good place to start. If it ends up working out make sure to let us know which method you used.
Link to the thread..
http://forum.xda-developers.com/showthread.php?t=1010807
just flashed 2048 on my mt4g. tested a few short clips which seemed to have improved. The 2nd clip there were only a few very slight pauses on video recording. This was off of a fresh reboot though, so I will continue to test through out the day as I use my phone more.
Update: The flash didn't seem to stick. as suggested by some others on the thread I'm now using/testing sd speed boost. Settings seem to stick, and so far there hasn't been any choppiness in recording hd. will continue testing and let you know.
Update: Doesn't help...still happens.
im on cmrc4, using the same sd card that came with the phone it is recording fine
could you try this out

um yes, thanks but no thanks. I have a compatible sd card. if it isn't i wouldnt be able to use wp7.
my card works and has always worked. even with android i had no problem.
So you're telling me you have super fast flick-ing action? I highly doubt it.
Anyone else with a better suggestion?
Yeah, I have one - change your SD card.
I have great scrolling, no lag at all. The SD card makes a huge difference. When I was using a class 4 kingston, wp7 was laggy and didn't run that well... it still ran and used the card, though. But now using a class 2 sandisk, wp7 runs as smooth as butter... no lag and battery life is much improved. What kind of card do you have? Cards with good random access speed is what you want for wp7... usually lower class cards have better random access speed than higher class cards. Class 2 sandisk seem to work consistently well, but I guess some people have had issues. But even cards that are same class and same brand, but have different manufacturing numbers or serial numbers will be very different performance wise.
i have a sandisk 8GB class 4. it has never had any problem.
are you guys telling me that by downgrading to a class 2, i may have a faster WP7 OS?
that is ridiculous!
can anyone confirm this?
I'm still using Class 4
I will backup my data and test this tomorrow.

You might... it really depends on the sd card. Sandisk class 2 cards made at one time can be very different than sandisk class 2 cards made 6 months later. Same with class 4 or with any sd card out there. When it comes to the random access speed, it can vary greatly... manufacturers don't test this speed and don't aim to make consistent scores of that. But usually the tricks that manufacturers do to get better sequential write scores on their chips end up hurting the random access speeds. That's why more class 2 cards are compatible and work better with wp7 than class 4, 6 and 10 cards. And if you are having lag, then that means you can definitely do better, because I have no lag at all at this point... maybe every once in a while I'll get a little lag here or there, but overall, it's VERY smooth. I haven't installed my apps yet... only like 10 or so apps from the market, and only copied one music album over so far, so maybe I'll get more lag when more is installed... not sure. I have 21gb partitioned over for wp7 on my sandisk class 2 32gb card. When I was using a kingston class 4, I definitely had a lot of lags and I hadn't even installed anything at that point. But I have heard that sandisk class 4 works good, too, but, like I said, when and what factory the chips were produced in can make a big difference with the random access speed which is what wp7 needs to be smooth.

Lag ???? WP7 is smooth as butter, this is why I'm still using WP7 over LAGGY Android.
ps: I'm using Sandisk 2gig class 2
It's all to do with your micro SD card, my old Samsung 8gb card, ran ok, but would somtimes lag, not load marketplace, things would crash and the occassional autoreboot as well, so I ordered one of the Microsoft recommended sandisk 8 GB ultra microsd cards, not a single lag, no crashes, things run so smooth and fast its really quiet amazing. How ever many times and different ways you format your card if its not the right one it will never run wp7 smoothly

You should take the class 2 sandisk back and order a class 2 sandisk from somewhere else... most class 2 sandisks work great with wp7. But like I said in several other posts, just because the brand and class are the same, doesn't mean the card will perform the same. They don't test the random access speed on cards so it's not consistent on cards, and it's random access speed that matters with wp7. I was just testing my cards today... I have one class 2 16gb sandisk with great random access speed and works great in wp7, and I have another class 2 sandisk that has bad random access speed and makes wp7 laggy. The read and write speeds were the same on the cards, though. My class 2 32gb sandisk has good random access speed, and my class 4 32gb sandisk I just got yesterday has even better, but my old class 4 sandisk 4gb card has terrible random access speed. My class 4 32gb kingston and my class 6 8gb kingston both have terrible random access speed as well.
Cards of same class from same manufacturer can have different chips made in different factories depending on when and where they were made. Also, a lot of the time, the chips the they make to have higher sequential read and write speeds will have worse random access speeds, so you will probably have better luck running wp7 with a class 2 than with a class 6 or 10. Microsoft reported this from their testing of memory cards for wp7. This doesn't necessarily mean a class 4 or 6 card won't work just as good or better than some class 2 cards, and it doesn't necessarily mean a class 2 card will work well. The problem is that the random access speed is not rated for cards so it's not kept consistent on cards. But at this time, it seems the class 2 sandisk seem to have the most consistent high random access speeds, but again, doesn't mean all of them will. Like I said, I have a class 2 16gb sandisk that doesn't work well (which is the one I bought retail), but the class 2 16gb sandisk that came with my phone works very well. Also, I just got a new class 4 sandisk 32gb card which I haven't tried for wp7 yet, but from benchmarking the card, it looks like it will work very well. I'm gonna test it with wp7 tonight.
Hi guys
Lovin WP7 but there is one thing that is really bothering me, the Market is really slow to load pages and to navigate around the UI.
It is the same on both 3G and WiFi, it is definately not my connection.
Everything else seems to work really well
Anyone else have this problem or know a solution?
Thanks
I have the exact same problem.. Scrolling is laggy, and the market needs really long to load new apps..
Using a compatible SD card fixed this issue for me
most likely it's your sd card, get a new one and try it.
Any other tips anyone?

No, it's probably your card. Especially if you get lag when scrolling. When using a class 4 kingston, it was laggy for me, but once I switched to class 2 sandisk, it was supersmooth, no lag at all. Get a class 2 sandisk.
Cheers for the help everyone, guess i am off to get a new card.
Thanks again

My 16gb class 2 sandisk worked fine. Im using a 32gb class 2 sandisk now partitioned with 21gb for wp7 and 8gb for android, and both are running smooth.
But there are different model numbers for cards of same class and brand that may have different random access speeds, which is what effects wp7 performance. They use different chips from different factories and sources depending on when and where they were produced, and since random access speed isn't kept track off and isn't consistent, they can vary greatly even if the card is same brand and class. Everyone is concerned about sequential read and write speed, which is what they are classed by, but that isn't as important as random access speed when running an os off the card. Actually higher class cards tend to have worse random access speed.

Hey I know that the main problem with the Evo camcorder is in how it is encoded and the main restriction holding back the quality is the speed of the sd card. I would like some feedback for those of you who upgraded their sd cards on whether it has had an impact on video recording.
Thanks
currently I have the stock sd card, but I'm considering upgrading if there is a significant difference in video quality
no increase on mine

I've had two memory cards besides the factory 8GB. One was a Sandisk 16GB Class 2 and the other is a Lexar 32GB Class 10. Video recording on the class 2 cards while panning at a good clip introduces artifacts into each captured frame, and the fps drops considerably. However, with the class 10 card, both of those are reduced significantly. The artifacts are virtually non-existant and the fps slow down only happens when moving the camera really fast.
I would definitely look into getting a class ten. Two cards that people are going with are the Wintec 32GB (avoid the 16GB) and the Lexar 32GB. Check out www.provantage.com for the Lexar card and www.newegg.com for the Wintec one.
I'm using a class 10 16gb, After looking through my videos, I would say there is a small improvement in quality. Mainly in the old videos I noticed every once in a while it would get pixelated, the new ones don't and theres less of a grainy look. One MAJOR thing I want to point out is on the old 8gb class 2 I was using a sense camera now I'm using the asop one in CM7.
I would just go spend the $30 and get a better card, it'll make your life better in every way!
anyone know what the threshold is for sd card classes regarding quality? in other words, besides faster data transfer speeds to another device what is the lowest class # needed to see improvement before its overkill?

Seems class 10 works well. If I get time at some point I'll try to do a test with similar lighting and such. I have class 2,4(?)6, and 10.
Also one point I want to make is I got my 16gb class 10 on newegg for $30(wintec, it has horrible reviews but mine works fine), but theres a ton of others and check out the accessories forum a lot of times people will post up when they find a deal.
If you just want more speed theres lots of 8gb class 6 for under $15. Micro Sd cards have dropped a whole lot in a short time

i dont care too much for faster data/file transfers to & from a computer as id rather spend the extra money for more storage than on a class 10 when a class 6 improves video recording just as well.
on the other hand, if apps or videos that are installed onto an external class 10 sd perform better than class 6, than itd be worth the upgrade, but im not sure if the phones processing power is the limiting factor or the weakest link, if that makes sense.
any one else care to share their thoughts of say a class 6 vs a class 10. I still have the stock class 2 in both my evos and video quality is very unreliable.
Thanks
I) Change the SD card.
-------------------------
Although Dell's stupid camcorder settings probably should not overload the class 4 card that comes with the phone for the most part, a 720p video I recorded using my Class 10 card has a bitrate of roughly 6MB/S, which is higher than the 4mb/s a class 4 card is supposed to be able to transfer. I changed to a 32GB Sandisk Mobile Ultra Class 10 and there is a noticeable difference in the smoothness of the video recorded. Some lag is still present(In reality the phone records at 23 fps as opposed to the 25fps Dell says it should), but for the most part the video is now acceptable. Maybe a placebo effect, but photos seem to be captured slightly faster.
II)Settings in the Camera.
------------------------------
This makes a HUGE difference in the viewfinder, where it's silky smooth one second and laggy as hell the next. Turn auto-banding on,change the scene mode to sports or something,and if you want change the white balance from automatic to something else.
More tips to be added as I discover them
Great tips! Especially your second point.
Thanks for the info!
Theres a lot of discrepancy as far as choosing the class of memory card for the dvp. Some users say stick with class 4 because its more likely to be accepted with the dvp, some say get class 6 or class 10 due to higher speed. However, is getting a higher class card riskier? I have read online that the phone may get bricked if you use an incompatible card and it is safer to use a class 4... is this true or is getting a class 10 card okay?
My personal experience is that there is no problem with a SANDISK card.(maybe other popular brands too, but Sandisk announced something about Windows phone compatibility, and the stock card is Sandisk too, so it's the best bet)Maybe if you use some cheap-ass no brand card then it won't get recognized, but I don't think you'd entrust your phone and all your valuable information on those. Seriously, get the class 10, it makes a lot of difference in performance and usability.
