Fraps Audio & Video Sync Problem

not CPU....
only Frontsidebus, my AMD Mainboard (MSI 790FX GD70)

my CPU is safely at 3,8gHz (3,4gHz is Original) overclocked FSB : CPU=1:19 (Original 1:17)

Frontsidebus 200mHz (200mHz is Original) normal

HT is 2000mHz (2000mHz is Original) normal

Northbridge is 2200mHz (1000-2000mHz is Original) Overclocked

Ram DDR3 is 1600mHz (1332mHz is Original) Overclocked FSB : RAM=1:4


in This Settings runs Fraps without any Problems
in This Settings runs Fraps absolut synchron
in This Settings runs Fraps perfect
and my CPU and RAM is Overclocked

my Playlist on Youtube, you can see all is sync: http://www.youtube.com/view_play_list?p=4DF44B45A341C05F
previous was the sound and lips from the NPC-Chars not synchron with the VideoPicture.
without changing Frontsidebus, i cant better Overclock my CPU and Ram (with Frontsidebus (217mHz) i can savely Overclock CPU to 3,906gHz and Ram up to 1736mHz, but the NPC-Lips in my Game is unsynchron in this setting)
I also stand with the Fraps Fine setting and all is good.

thx for reading my Post, and i hope, it will be helping other Users.

OP here and its sure been a long! time since Ive been able to record without that GOD AWFUL delay that seems to come from HELL its-self..

I have good news and bad news about this particular issue.

Good: It is fixable.. I was playing about with different driver from 3rd party to beta for almost all components on my computer. (no O.C.) and got to the point were if i installed the latest drivers for my video card then work!!! thats right sync and all! BUT!!! as soon as i restart it goes RIGHT back to the way it was. That was lame. Worked every time none the less...

Bad: I finely BROKE.... I reinstalled my OS with RAID0 and ALLLLL my issues are gone video is great and so is audio?!@?!?

Here is a video with my fresh OS install. (& fraps workin

I HOPE to god someone can benefit from all this BS.

THANK YOU for all the support in helping me find a solution. You guys ROCK. ttyl off to work i go!

Video/audio sync issue

Hello, everyone!

I'm very new to these forums and looking for some serious help.
So. I'm using Fraps 3.2.3 (which doesn't really matter, 'cuz this issue happens everywhere). In every single recorded video audio isn't synchronized.
The audio/video lag is increasing with progress of the video.
I'm getting 0.5s-1s delay after 3 minutes of recording.

I googled alot, read many forums and still I couldn't get it fixed...
This is the list of what i did:
-Reinstalled drivers (soundcard, graphic card, motherboard)
-Changed versions of drivers
-Reinstalled system (tried with 32bit and 64bit)
-Formatted everything
-Changing sound device (Issue happens on my Realtek HD and Creative HS-1200 with X-Fi Soundblaster)
-DriverSweeper clean up
-Audio device settings (changed sound frequency, depth)

That's quite much and now I'm completely out of any ideas.

So, please, PLEASE! HELP ME! D:

I didn't had this issue earlier untill i installed 64-bit version Windows 7...
Then I went back to 32-bit - didn't help
So I formatted and reinstalled everything again - no difference...

PC Specs:

CPU: AMD Phenom X4 9550 2.2GHz
GPU: GeForce 9800 GT 1GB
RAM: 4GB DDR2
Motherboard: ECS Nettle3 MCP61PM-HM (more info: <Long link is long>)
Sound cards: Realtek HD Autio and Creative X-fi Soundblaster (HS-1200 Headset)

DxDiag: http://pastebin.com/SDtyd73k

I'd be very grateful if someone could help me.

Thank you.
Best regards - Q009

Video is faster than sound in my case

Hi Guys,

I was having this exact same issue. Running windows 7 x64. Have an ASUS Striker II Extreme 790I SLI mobo, SoundMAX HD Intergrated Audio, EVGA Gefore 460 GTX, 6gb Corsair DDR3 1333 (Had 8, however, a 2 gb stick went bad, had to take it out)...I would record video and sound would be great, however, the sound would get more and more out of sync the further into the video it went.

Was going crazy trying to sort this out, un-installing and re-installing audio and mobo drivers, changing the audio playback frequency...all the fix suggestions in this thread..

Anyways, I fixed this by removing the Asus AI Suite and the EPU system that is installed with the suite, also switched my power settings to 'High Performance'.
Through research on the web and on this thread, their are some references to overclocking having an effect on how fraps records video and audio, unless its stable or if you have automated OC, which will OC your cpu and memory dependant on demand, in a bid to save energy, like Asus EPU and AI suite, your video and audio will be desync'ed.

I hope this helps some ASUS Win 7 x64 fraps users.

Seriously? i have to uninstall some of the useful features to use fraps? Can i jsut disable them?
-ASUS Maximus II Formula LGA 775 Intel P45 ATX Intel -SAPPHIRE 100251SR Radeon
-HD 4870 X2 2GB 512-bit
-WD 7200 RPM drive SATA
-Intel Core 2 Quad Q9550 Yorkfield 2.83GHz LGA 775,
-mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
-Win7 x64
-supremeFX X-Fi audio card

The gentleman a couple posts above says he needed RAID 0. That sounds a little extreme a solution for this application. To run a $39 app I need to buy another $100 harddrive and reinstall my system?

Many thanks to you good Sir!
I have tried to figure out this problem for months now, with no luck.
These to simple steps solved the problem!

NB Installing RAID 0 didn't have any effect on this, that guy probably didn't install those crappy Asus tools after his fresh install.

Unfortunately many of these "fixes" people have mentioned are unreliable and there are obviously other things factoring in here.

I have exactly the same problem with my audio, as the video progresses it gradually gets out of sync until it creates a new file. Sometimes it remains out of sync, sometimes it re-syncs with the creation of a new video file.

I loaded up a test recording I just made in sony vegas and the audio track is approximately 0.60 seconds shorter than the video file, and the resulting gradual audio de-sync is approximately the same amount of time.

I have a very reliable way of testing the audio sync as the game I'm testing it in is a game called Black & White. Every time you click your mouse your in-game hand touches the ground and makes a sound, so it's very easy for me to test the audio de-sync.

I tested it on my 500GB drive which I normally use to dump the FRAPS files to, I also just did a recording test on my super fast SSD drive used to run my system which is an OCZ Vertex 2 120GB SSD drive, one of the fastest SSD drives on the market and there is still that same amount of audio de-sync after ~2 min (however long a single ~4.8GB file can be, the size varies slightly so as will the video length).

I too have tried multiple versions of FRAPS but it does not solve the issue.
I just did a test running at 720p instead of 1080p and the issue still happens.

I am at a loss for this because the "fixes" others have listed seem to be fluke fixes that do not work for everyone., and I have tried almost everything else to resolve this issue but nothing works.

I haven't used any other video recorders so I can't comment on that.

I'd really like for something to be able to fix this because as mentioned sometimes the audio re-syncs when Fraps creates a new video file but sometimes it doesn't. The audio sync becomes horrendous if it doesn't re-sync at the start of a new file because it just continues to get gradually worse. After ~6 min or so it's up to almost also a 2 second gain over the video playback.

I'm just learning sony vegas as I previously just used Virtualdub and in virtualdub what I would do to compensate was delay the audio somewhat to "try" to make up for it but sometimes it was so bad it was impossible for me to fix. Maybe in sony vegas will have a better solution, like I said, I'm still learning.

Messing around with fraps once again, and again Im encountering this annoying audio sync problem.

To me it seems simply a problem caused by the saving of the 4 GB video file chunks. For every chunk the audio track gains almost 0.5 sec ahead of the video track. When I record at 30 fps and 1280x720 res the 4GB chunks contain about 3 minutes of footage. Between the beginning and the end of one chunk the video-audio delay doesnt seem to change. At least I cant hear any difference between the start and the end of a chunk. But I can hear a distinct difference between the end of a chunk and the start of the following chunk.

ATM Im using Virtualdub to merge all AVI chunks to one large uncompressed file, and YAAI (thanks to Sniff for the tip!) to stretch its audio track by about 0.2%. This YAAI tool allows to adjust and test the audio synching in real time, and it saves the changes instantly.

Its no perfect solution but it isnt much extra work and the results are decent.

So my Issues were caused by the EPU-Engine. I Installed Windows 7 64 with crysis demo on a 16gb flash drive and was able to record to another HDD with no sync issues. As an experiment I installed the Turbo-V tool. No issues.. Then i installed EPU Engine and the issue pop right up. Once EPU was removed fraps started working right away.

Thank you guys for your help. I've sent a very....very detailed email to fraps letting em know what we've found out.

I also sent a email to asus with a lot of the same info.

I realise this is a necropost but when I googled "fraps audio out of sync" this post was listed, so I am putting info here for others who search.

I too was having this issue when recording games with a high widescreen (1680x1050) resolution. Changing from Full-size to Half-size in the Fraps Movies options fixed it completely and immediately for me.

I also have this issue - see this thread: http://frapsforum.com/threads/fraps-sync-problem.205/

I've tried all the suggestions but nothing has worked, including recording at half size which I always do. I also have a Realtek HD audio with the latest drivers.

Unfortunately there has been no response from Fraps on the other thread! Will there be here as this issue makes Fraps pretty unusable to me, having to sort out numerous 4gb files that are slightly out of sync towards one end of the file is a major PITA...!!

EDIT - I have found that the length of the audio is longer than the video and if I shrink the audio to fit then it all goes in sync. Obviously I would prefer to not have to do this to each 4gb file but maybe this info would help someone solve this problem that affects so many of us. Here's hoping...!

For almost a year I was using Fraps with no issues until yesterday.

For some reason audio started to go out of synch.

I tried everything.
Limit Framerate, reinstall Fraps, update Fraps( 3.4.5 BTW), use this trick and no success.

Please help.

OK seriously, is there anyone with solution for this?

Never mind guys. It looks like it's only a problem with KOTOR 1.

When I switched to 32bit 44100 Hz( Studio Quality) ME2 and few other games had out of synch issue but after I switch it back to 16bit 44100 Hz( CD Quality) after I read comments in video I linked it now works fine.

I've searched the web trying to find a solution to this issue. Doing the suggested fixes only seemes to exasperate the problem. Any one have any ideas? My specs are:

ASUS Crosshair V Formula AMD 990FX Gaming Motherboard
AMD Phenom II X6 3.3 GHz 9MB Total Cache
EVGA NVidia GeForce GTX 560 Ti 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP

I'm using the on board sound. I just built this rig over the weekend and ironically my older computer never had this issue. I even uninstalled the ASUS EPU program as suggested in a thread another thread to no avail.

If there is no getting around this, is there a decent freeware video editor out there which would allow me to manipulate the audio track manually to sync it back up?

Many thanks for any insight/suggestions!

Edit: I'm changing all my devices to 44100 Hz per one of the threads here. I did not change everything before, just the one playback device.

Now it's slightly too slow. This is infuriating.

I've just experienced the same problem using FRAPS 3.4.6. to record a live gameplay event. Everything starts off fine and then the audio just gets further and further ahead of the video, and finishes before the end of the film, so the last portion of the video action is completely silent.

To make matters worse when importing into Windows Movie Maker, instead of the audio and video sequences being re-synced to match each other it seems that the WMM import routing simple cuts the video off as soon as the audio finishes so you lose all the silent footage.

Basically I need some way of resyncing the audio and a video, and ideally some solution to stop it happening in the first place.

Here's a summary of successful audio sync solutions from this thread and elsewhere, in random order.
NOTE - no single solution works for everybody...

1. Don't try to play the raw Fraps file. Encode it then evaluate it. Try more than one encoder.
2. Try a different media player.
3. Reinstall video driver. Reinstall sound driver too, what the heck.
4. Reinstall chipset driver for your motherboard. (I can confirm the importance of this one)
5. Uninstall old programs you don't use that might be messing with your system somehow.
6. Set Windows Power Properties to "High Performance"
7. Disable Asus AI Suite and the EPU Engine (automatically change system clocks - BAD)
8. Set sample rate to 44100 Hz. Set sample rate to 48000 Hz. I dunno! (Setting is here - see last image)
9. Use another sound card.
10. Get a USB headset. (or USB microphone) (just goes to show how strange this problem is...)
11. Don't overclock the Front Side bus. (CPU/GPU overclocking should be OK)
12. The problem seems to be related (at least sometimes) to what others see as Freezing or
    performance drop off.
13. Don't try to record at settings where you can't hold the frame rate (test for dropped
    frames explained here and here)
14. (related to previous) As a test, record at 1280x720, 30fps, half size and see if that fixes it.
15. (related to previous) This guy installed RAID and the problem was fixed. How about that....
16. Some games have trouble with the newest computers. Search the help forums for that game.
17. Disable Spread Spectrum Bus Clock
18. UPDATE: uninstall "Easy Tune 6" (post #126) [another clock-changing program!]

Workarounds:

1. Use a tool like YAAI to sync the audio after recording.
   (only works on individual 4GB segments)
2. Change the video frame rate in VirtualDub etc (workaround #1, inverted)
   Virtualdub Video menu, 'Frame Rate...', Change so video and audio durations match
   (only works on individual 4GB segments)
3. Record audio in another program like Audacity and assemble the sound later.
4. Re-encode with VirtualDub "direct stream copy" - see this post.
   (only works on individual 4GB segments)

Workaround #1, #2 and #4 will work only with individual 4GB segments...

or with all segments, assembled.

Note this problem occurs with other video capture tools also, not just Fraps.

If you have another solution let's hear it. If you fix your problem, please report back as to what worked.
. . . . . . . . . . . . . . . . . . .
EDIT - my opinion now

A pattern has emerged: One scenario is that something is changing the system clock(s) for power saving or performance reasons; the system is confused by this (the audio sample clock is affected) and samples audio at some incorrect rate. The AVI metadata "claims" a standard audio sampling rate *, probably 44.1kHz, and that's the rate your media player/editor decodes it at. Hence, audio drift - one way or the other.

Another scenario is that video frames are being dropped, (more precisely, Fraps inserts dummy P-frames as needed) due to recording at a data rate the system can't handle - and your media player/editor is not handling those dummy frames as it should *, but instead it deletes the frames, shortening the video. Hence, the audio is longer than the video. You can diagnose dropped frames with VirtualDub.

The clock scenario is behind solutions # 6 to 11, and probably # 4. UPDATE - and 17 and 18.

The frame drop scenario is behind solutions # 12 to 15.

That leaves special cases # 5 and 16.

* If someone can correct my half baked explanation I would appreciate it

I just used this list to get rid of the 4gb file lag. thx a lot! the "freezing problem" was my problem as well.

the problem was avast! you have to make a rule for the program not to scan the /fraps directory and the directory where you record the video file. fraps is now starting insanly fast (before it took up to 10 seconds) and there are no lags at all. this really works!
