Lag in recording 720p video. - EVO 4G Q&A, Help & Troubleshooting

Every ROM I've tried, I have always had this lag between the video and the audio. Is there a way of fixing this or what could be causing this issue? I've issues of this appearing in Synergy and KingRoms.

I have used both of those ROMs (builders) with no issues. One thing that helps tremendously is a good and fast SD card. Reads and writes with a higher class SD prevents alot of lag when recording video. Try a class 6 or higher. If I am not mistaken, the I/O on the EVO 4G only supports up to class 6 anyway.
Good luck!

I'll look into that, thanks!

[Q] Movie playback (on phone) problem. can anyone verify?

Hi all,
I have an unrooted unbranded Desire on latest firmware.
When I record a sample 30 second HD video it plays back on the computer fine.
However, when I try to playback a HD video from the gallery on the phone it stutters and plays very badly the first time. If I play it again immediately it is perfectly smooth. It's like it has cached it the second time so it plays smooth.
Can someone check this on their phone and tell me if perhaps it's just my card speed (class 2). I think it may be the card because of the fact it only stutters the first time like its trying to read/play at the same time. On second playing it's fine.
any feedback would be great. thanks alot!!!
Would anyone like to try and replicate it? just record a 30second HD video and play it back on the phone. Is it smooth on first playback or does it stutter.
I think it might be the memory card, but don't want to shell out 60euro on a class 4 unless I'm mostly sure. thanks alot
Myself and others have been experiencing much slower SD card speeds in Froyo than in Eclair. See this thread and this one. I think that your problem could be related, and if so buying a faster SD card probably won't help.
thanks Koider

[Q] [Music Playback] Massive Stuttering

I am having the most annoying issue with my EVO. I have the 0003 version of the EVO and I am using a WinTec Class 10 SDHC card. The problem I am having is that whenever I listen to music I get stutters. This happens when I am not running anything else in the background. I have tried several sense ROM's and ALL of them do it. I suspect the SD card as the test shows 4mb/s write and 6mb/s read. Anyone have any input?

[Q] video recording performance.

I'm running cm7 rc1 with savagedzen 009. Recording without too much motion and action is fine but recording in my car when I drive causes the video to lag behind quite a lot. This is using the HQ setting in the video recorder in cm7. This is a nasty issue since the longer the video the worse the syncing issue is. I'm using a class 6 SD card
Would a higher class card fix it or am I sol?

[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.
