Video capture and playback issue - EVO 4G Q&A, Help & Troubleshooting

For a few months now it has seemed that video is hit and miss when I use the camera on my phone. Some videos will be just fine and others will suddenly pause or skip and the video falls behind the audio quickly. This issue has been across multiple roms for me at this point. I had read somewhere about A2SD causing issues like this but am not sure if that could be it. The memory card I am using is the one that comes with this phone running a ext3 for the A2SD.

Are you talking about playing back videos or capturing them? If you are talking about playback, what details are the files? What codec, resolution, bitrate?

Always better to run most audio/vid apps, of any kind, from internal memory and not sd, otherwise it is like trying to run internet on dialup speeds nowadays Compression is nice but something has to give...

Video captured from the camera on the phone. While taking the video everything seems just fine. And sometimes a 1 minute I take everything will be fine, other times just 30 seconds and the audio is way behind. The playback is always the same result if it be from the computer or the phone, so I assuming the issue must take place when recording.

I don't know of any way to change how A2SD handles this, from reading it doesn't seem most A2SD user's get hit with this issue.

My issue turned out to be having the swap not set to 0

KS20 Stuttering/Laggy Video Recording

I've recently been noticing when I actually went ahead and utilized the video recording functions of my KS20, that it stutters horribly during recording - as in, it literally freeze-frames every few seconds of video, which makes any recordings really horrible to watch. I know on my old phone, which had the same sort of 2MP camera, I never experienced such issues.
Is there a driver patch or update I can be directed to in order to rectify my problem?
Cheers for any assistance.

try to record on internal storage
I have it set to internal, and there's plenty of space for it to use to store the video. It just keep stuttering - with plenty of ram free as well. I'm quite lost as to what's the problem exactly.
Sorry to resurrect my old post, but I'm still having the problem despite fiddling around with it insistently, to no avail.
Basically, I'm storing on the internal memory, with plenty of RAM free (original ROM as well). I record video and every 2-3secs it freeze-frames or stutters for a moment, and does not stop (recorded 5mins and it kept doing it). I really need to understand whether it is a software issue, or an issue with the firmware, or if it's hardware and i need to get it repaired. The camera takes perfectly fine photographs and i have no other problems.
Any ideas/fixes that I could be informed of would be great.

Choppy video recording playback question.....MAYBE SOLVED for me

Apparently I get to research this fun issue now. Anyways is there any correlation between choppy video play back and recording in low light situations?
The vids I'm recoding right now are in semi low light but I can still see what I'm recording, but during play back the video seems to pause then continue. Sometimes its very bad sometimes its just every once in awhile.
I have adjusted recording resolution and encoding but there wasnt any change.
Any ideas?

Ok thought i d post back with some findings.
I'm using a pc to actualy watch these vids to better look for issues and isolate at what point the pauses and glitches are introduced. It seems that its having a hard time actually making the video. Not play back, because my pc plays back the crappy video just as crapy as my evo.
I got the video to stop freezing and pitching. I'm not sure what fixed it but I believe it was fixed by running a check risk on my SD card.
I noticed that everytime I connected my Evo to my pc via usb and used removable storage mode my windows 7 would ask if I wanted to scan and fix or not. I was telling it no, but after I did thus scan my videos want back to being pretty clear and not choppy.
Thought I'd share my findings.

Are the video recording issues fixed after 2.3.3?

Searched but couldnt find anything except SE said that the video recording issues will be fixed in 2.3.3. So can anyone confirm they were fixed (freeze,stutter, audio sync etc.) Thank you
The video stutter issue was found when I was using an old class 2 micro SD card on 2.3.2. After I have changed to use a class 10 card from Transcend, the Burroughs recording issue wad not found (before update to 2.3.3), see if I have time to test back the previous slow card on my updated 2.3.3. But anyway I suggest you get a class 10 card since the system use the SD card heavily for storing application data, this will improve the system performance, especially the gallery appear, and seems pretty much everything.

hopefully it works..
I never experienced this in 2.3.2 but maybe because i changed to 16gb class 6 right after purchase
Confirmed as fixed, I have taken multiple videos with 2.3.3 and no glitches. with 2.3.2 I did have some.
i have not recorded much before 2.3.2, but made some recordings post 2.3.3 and no issues at all.
rumnyc, bustervic,
What is the class of card you use?

I thing class of card is not important in this moment because whatever card rumnyc used on Android 2.3.2 he had problems with recorded video and after update on Android 2.3.3 he don't have any problems. For me this issue is fixed. Personaly i didn't have any problems on Android 2.3.2 with recorded video.
So far I have not encountered any problems, have recorded 3 X 10min clips and have not seen or noticed any undue pausing as I did originally before updating to 2.3.3. Iam still using original 8Gb card that was supplied in retail package.

Poor playback of recorded video ??
Rather than start another thread on poor video recording I thought I'd ask for some help here. I have read all the XDA threads I could find on the problems of video recording but still don't understand where the Arc is at on this particular problem. I do have the 2.3.3 update (flashed UK O2 .145 firmware) - everything on the phone works great for me, except this problem.
Yesterday, I tried out video recording and while I was actually doing the recording I was very impressed. I was filming in a massive indoor barn where my kids were jumping during a horse riding lesson, so lots of movement and a little bit of moving the camera around in the video.
I liked the fact that I could see on the screen that the lens picked up most of the width of the barn, so I had to do little moving left and right with the camera. I got used to where the lens is positioned so didn't have any problems putting my finger in the way.
I watched the videos back on the phone straight afterwards - looked great. I was really pleased with the whole taking a video experience.
BUT, the problem is that when I transferred the videos on to my computer and tried to watch them, they are incredibly jumpy, lots of missed frames and jerkiness - nothing like playback on the Arc. Basically, they are unwatchable. I played them back in lots of different media players - all the same.
I recorded in HD, with and without image stabilisation, everything was really quick on the phone such as starting each recording, and the film was almost immediately available to watch once the recording had ended (something that even my old digital cameras couldn't do so quickly. I am only using a Class 2 Sandisk card but I don't see that can be the problem.
Please, if anyone can suggest a fix or explain what the situation is - I didn't even know there were recording issues on the Arc until I read that they were fixed with 2.3.3 (and thats what I have on the phone).
Thanks

Look Frenchdroid,dont worry u r are is prefectly fine as far as i know
u r camera is perfectly fine
they problem lies in your computer or lappy
i thnk your computer graphic card or hardware is not capable of playing 720p(HD ready) or 1020p(full HD) videos,thats why u r experiencing this problem of dropping frames and installing media players or updating codecs wont solve this problem but upgrading your computer hardware may do the trick...........
IF my post helped you use thanks button....
Hey - thanks for your reply. You know what ? You were right. I feel like an idiot but hey, at least I'm a bit wiser now I'm not used to all of these video formats and stuff like this.
do not worry we at xda , are like a family,always ready to help each other......

[Q] camcorder video/audio sync

most videos i record has audio and video out of sync even lowest resolution (VGA)... it mainly happens after first 1min or less... it is very annoying.. is this normal?
i am on leedroid gingerbread a2sd+
getting worse... now the video is fine for first 20sec and then it's chaotic... there's huge frameskips... image freeze... audio finishes very early.. video is like 2min without audio .. is it normal?? recording on wvga....
I have the same issues, anyone know how to fix it?
bump!
me 2. really curious to finally hear something about it. i've had this problem since day one after rooting and flashing custom roms...
If that happens even at low res, then the problem might be your SD Card.
Look up SD Card class.
I recommend a class 4 minimum.
Most ROMs have issues recording on 720p, but that might be an hardware problem.
It's just not enough and it starts skipping frames...
You should also check the main thread for your ROM to see if there are any reports of those same issues.

[Q] HD video recording - audio sync problems

As a HD video recorder my Galaxy W is not fit for purpose
If I record videos longer than about 60 seconds, the audio and video start to get way out of sync. I don't think it happens gradually - the sync usually goes out after a short glitch in the video. With each glitch, the video falls further behind the audio, and it never recovers - it just gets worse and worse.
I see the problem when recording to either an external SD or the internal storage, so it's not an SD card speed issue.
The problems go away when I record in a lower resolution (480p is fine), but one of the reasons I bought the W was for its HD recording capabilities!
Does anyone else have this issue, or is it just me?

I didn't check this problem in Recording, but i found the similar problem in playing 720p video. After a few seconds the audio is out of sync.
I thinks its purely a software problem, and future update will resolve this.
Currently i have 2.3.6.
Thanks
Yeah, it's not just a playback problem - if I transfer the videos to my PC the same glitches and audio sync issues are still there. I think I'll try and report this to Samsung if I can bear the pain of negotiating their support website.
Sometimes I also experience this when recording 720p video to internal storage, but no problem when I record to external microsd class 10 card. I assume this because when I did benchmark the internal storage writing speed only about 5MB/sec while the external storage reaches 15-17MB/sec on writing speed. What class is your external micro sd?
As for playback sync issues, I did not experience it either...
That sux. I havn't looked it up on my phone yet, but I really need my camera for recording this weekend. So It better not be that problem on my phone.

My external card is only class 4, but I naively assumed that the internal storage would be up to the task even if my external card wasn't. Looks like that might not be the case. 5MB/s - is it really that bad? If so, that's seriously crap.
I noticed the same with internal SD
Did not yet make HD video's using external SD. Hopefully that will resolve it.
Csn galaxy fit record hd videos to about 480p somehow as its having a powerful 5mp camera...?? Plz help me .. I need to record hd videos with my fit these vacations
