Audio sync problem with screen capture/gameplay video from Bandicam, converted by Freemake.

I recently purchased the student discount for Adobe creative cloud which gave me access to Premiere Pro CC which I've been using to edit my YouTube videos.
I use a popular recording software called Bandicam to record my PC gameplay. Bandicam like many other software's allows me to record my commentary OVER the gameplay. When I play back the recorded video in windows media viewer the audio and gameplay are in complete synchronization. I then use Freemake Video Compressor to convert the recorded gameplay from an AVI file to an MP4 file. Then I import that file into the latest version of Adobe Premiere Pro. When I play back the video during editing, the audio and video appears out of sync by about five seconds.
Like I said, I don't record my gameplay and audio separately like some other people, so it can't possibly be an editing mistake. I've tried dozens of different editing software's (all free crappy ones) and everything is fine. This issue only occurs with Adobe Premiere Pro. I have installed the latest update of the program and have just recently tried re-installing it as well. Nothing seems to work for me, or for the many, many people who I have seen in random forums all over the net with this same problem. It appears to be an issue that isn't only happening to me.
Due to this issue, I'm very behind in my YouTube schedule. Apologies if this is rather long, I just want to get what I paid for.
Thanks for taking the time to read and respond

Premiere cannot handle clips with variable framerate.
Your converted clips need to have constant framerate.
Otherwise use a converter like Handbrake.

Audio Sync Problems With Share YouTube -- OSX not iOS

I've replicated this several times. It's maddening and bizarre. *Share YouTube*
Exporting a FCPX video using the "SHARE" menu and choosing YouTube causes the resulting upload to be out of sync when viewed in Safari or other browsers on iOS
Viewing the same video on the iPad with the built in YouTube app, the video plays in sync
Viewing the same video on AppleTV 2 (with the 5.1 update), the video plays in sync.
If I export using Export Media menu item under the SHARE menu, and then from QuickTime Player choose Export For Web (under the File menu) and manually upload, the video is in sync.
Note, that using
Feel free to try on this short simple and silly video http://www.youtube.com/watch?v=cGTQNMJdPRQ&list=UUiDxioBFJCPC-8OUFifsx8A&index=2 &feature=plcp
Anyone else experience this. Is this a bug or a feature? Rather not go through three steps to upload a simple YouTube video.

We've got the same problem and yep, it's infuriating that are so few posts about it.
It doesn't happen with every video, but the vast majority of files that we've tried to either export directly to YouTube from QTX or export locally and then manually upload to YouTube end up with shockingly bad audio sync (and also some colour issues, but that's another story).
As a small video production company we were chuffed to bits with the improved export speed in QTX and quick to make use of it. But when we realised there was a problem, we had to revert back to using QT7's painfully slow export.
We've run experiments on a brand new iMac and MacBook Pro running the most up-to-date version of OS X and still no joy. Always the same audio sync problems with the same video files.
In the meantime however, we've found that the settings advised on this YouTube help page have given us the best (albeit slow) results at both 25fps and 30fps when exporting from QT7:

Audio sync problem with videos imported from iPod Touch

I have an iPod Touch 4th Generation that I used to shoot video at a family birthday party. When I imported the footage into iMovie '11, the audio is not in sync with the video (video is about two seconds behind audio) and there is only the left channel of audio. I verified that the video on the iPod plays just fine--no audio sync problem, both left and right channels work. I just upgraded to iOS 5 on the iPod Touch. The iMac is running Snow Leopard 10.6.8.
As a workaround, I can import the video into iPhoto instead. When I play the video in iPhoto, there are no audio sync problems and both channels of audio can be heard. I have imported other iPod Touch videos successfully into iMovie '11 in the past few months, but this has been the first time these problems have occurred. Any help would be appreciated.

Audio sync problem on long captures

I have an XL1 and have noticed that on some of my captures that are rather long - I have a sync problem with the audio and video as you get deeper into the video.
I have chopped up this capture by limiting it to 10 min max lengths.
Any other way around this?
Thanks!
Tim

The most common cause of sync problems is due to mis-matched audio sampling rates between the captured clip and your FCP Sequence settings (typically 48hz, 6 bit stereo). Check to make sure they match exactly.
Also, it can make a difference HOW you capture; are you logging the clips then batch capturing after? Or just using Capture Now? Capture Now has been known to be problematic in this area, especially when Canon cameras are used as a capture device. Since Canon has a rather loose implementation of the Firewire standard, set Device Control in FCP to "Firewire Basic" and use Log & Capture instead of Capture Now.
As an alternative, use something other than a Canon device for capturing purposes.

Problem with screen capture

The first problem is I successfully captured a video from my DV camera, but when I put the second tape in to continue, it can't find the camera again. I've re-booted but nothing worked.
Any suggestions?

And which program? In any case, ask such usage related questions in the product specific forum.

Audio sync problem with sony video walkman input

i purchased a sony video walkman to ingest mini dv into fce1, using a 1ghz g4 imac with os 10.3.9. 256mb of ram. i made the purchase to overcome the same sync problem i had when ingesting long clips directly from a canon xl-1.
i'm connected with firewire. audio is 16 bit (shot on an xl-1) and i've checked and rechecked the preferences and other relevant settings.
i'm buffaloed at this point: how can i capture longer clips without a loss of sync?
could the problem still be related to having shot the material on an xl-1? could it be related to only having 256mb of ram?
imac g4 1ghz 256mb Mac OS X (10.3.9)

yes, i have...i've also deleted fce preferences files as well. i'm wondering if reinstalling the program will help this situation?

Frustrating audio sync problem with MJPG clips!

I make short films from our family trips, using the jpg:s and mjpg clips made with our Canon compact digital camera. This has worked fine (since PE 2). Now I often get a frustrating audio problem on SOME of the MJPG:s, SOMETIMES.
When I play the clip in PE7, after 0.5 - 1 sec the audio jumps back to start, before it continues to the end along with the video. This makes the audio out of sync with the video (lagging 0,5 – 1 seconds).
The only way to fix this is to separate the audio track from the video, cut the start of the audio (to where it jumps back to the start) and then move the audio track to make it in sync. Besides being a tedious way to do on all clips, the audio track is not possible to extend “in the other end”, so I have to cut the video at the end as well…
However, this is not happing on all MJPG clips but only on some.
Also, the clip looks fine in other programs, e.g. wmp or windows movie maker.
I have tried other MJPG decoders but that does not make any difference (so it’s obviously no problem with the video). The audio is PCM Audio 44100Hz, 706 kb/s mono.
Now, when I tried repairing the PE7 installation, updating DirectX, removing all caches in the project directory, rebooting, it worked! The clip I was testing was in sync!
But, the next day I noticed the sync problem again on a lot of other clips… I then thought I should try to force PE to reanalyze the video again, so I remove the cache-directories (did not help) and moved the project file to another directory (this did not help, but on the other hand, I didn’t see PE7 analyzing the video again, so maybe there is a cache somewhere else??)
I noticed (looking at properties on the clip in the preview window in PE7), that the original audio is 44100Hz mono, but PE7 converts it to 48000Hz mono. Don’t know if there is some problem there, but it should not be any difference on different clips from the same source… (and the “jump back” in audio is 0,5-1 seconds regardless of clip length, and not the 9% that the difference in frequency would suggest + the audio plays in “normal speed”).
I’ve run out of ideas!!
Please, does anybody have any constructive ideas or tips on what to try? Are there more caches to clear? Are there conflicts with another program, like wmp?
(I use PE 7.0 on a 4Gb, quadcore system running Windows Vista Home Premium 64 bit.)

Thanks, I suppose I can start batch-converting my mjpg movies before importing them inte PE7, if that would make this problem disappear. I'll try that (I have FormatFactory installed, but VirtualDub seems like a nice tool if that is better), although that would make the process a bit more long-winded...
Regarding GSPOT info on a file that works and one doesn't, there are typically no difference between them (except length and content, of course). In fact, as I mentioned above, the same movie did not work until I did some reinstalling, clearing caches etc. Then the same movie suddenly worked OK again.
I attach the GSPOT info on that file.
(I never had this problem on my older XP system that run PE2...).
I will try converting to see if the problem disappears.
Thanks!

Audio Sync Problem with Uncompressed HD Quicktime

Hi,
I have an Uncompressed 10-bit 4:4:4 BlackMagic Quicktime file (it's about 250 GB) that's a silent version of my short film. The video plays back at 23.98 fps.
I'm now trying to sync my final sound mix back to this video in Final Cut Pro 6. The sound is 48kHz, 16 bit, matching that of the timeline. The video settings also match the timeline. I have it synced at about 5 minutes in, but by the end of the movie (20 minutes or so) the video has drifted AHEAD of the audio. So the audio ends up playing a second or so BEFORE the point where it should.
What's wrong here? The mix was exported from ProTools at 24fps, matching that of the film. In a different video version of my film the audio is playing back at 47.952 kHz with 23.98 fps video. Would that be the cause of this phenomenon?

Video is 23.98 fps...audio is 24fps. With that information I'd deduce that audio and video would fall out of sync after too long.
In a different video version of my film the audio is playing back at 47.952 kHz with 23.98 fps video.
Should be 48Khz...

Stratosphere- Problem with Screen Capture and Group Text Reply

I have a problem with the side button that locks/unlocks the phone. I don't know why it happens but sometimes when I press the side button to lock the phone it takes a screen shot and send its to my Gallery under the folder ScreenCapture. I can't figure out why it does this sometimes, and when i want to actually take a screen shot I cant.
Anyone know how exactly you can take a screen shot?
Another question i have is with Group Texts. Is there a way to reply all when I receive a text that was sent to multiple people or can I only reply to the sender?
Hope someone can help thanks!

Hello kfeatherstone! I can provide you with instructions for taking a screenshot:
1. Press both the Power and Home buttons briefly.
2. You should hear a “click” sound and the screen will say “Screen captured. Saved as image file
In regards to your messaging, "reply to all" is not an available option. I hope this information helps!

Avidemux audio sync problem with MPEG-2 - alt. way to cut mpeg-2

I have a PVR-250 and when I load up an MPEG-2 file that it generated in Avdimux, the audio/video is out of sync (before I make any edits). My goal is simply to cut out commercials in the file, nothing else. When I play it in any other viewer (vlc, mplayer, etc.) the sync is perfect. I found that this is known issue with Avidemux. See below.
Can you guys recommend another piece of software I can use to simply cut parts out of mpeg-2 files?
Taken from mythtv wiki page. I quoted the relevant text from it here:
Cory Papenfuss noted:
I would just like to add again that this procedure only works 95% of the time for broadcast/cable captures... about 80% of the time for tape transfers. Avidemux cannot deal with chaining A/V sync throughout the file, and this method will have broken sync with one of these unfortunate captures. The author of avidemux acknowledges this limitation, but says a fair bit of internal work would be needed to fix it.

Thanks, I suppose I can start batch-converting my mjpg movies before importing them inte PE7, if that would make this problem disappear. I'll try that (I have FormatFactory installed, but VirtualDub seems like a nice tool if that is better), although that would make the process a bit more long-winded...

Audio sync problem with mpeg streamclip

can't match audio up with video once imported to fcp

Hi There,
The same problem is happening with me as well. I keep getting the "analysing audio" message and my clips are 24 or 25 frames out of sync.
I am currently working on a mixed format project - DVCAM and HDV capture into a DVCAM sequence. The DVCAM clips are causing the problem. The HDV clips are fine. I wondered whether it might be a mixed format issue - switching between capture codecs within the same project? Is that something either of you guys are doing? What camera was the footage recorded on. The pictures I'm struggling with were recorded on an Ikegami and I'm capturing from a sony deck.
I have found an easy workaround. Put your entire out of sync clip into the timeline. Correct the sync then drag it back to your bin. You'll get two clips with the same name which is a tad confusing but the one you've dragged back will at least be in sync.
I remember having this problem years ago without explanation. It hasn't then happened for years until now.....
I'd be interested to know if you get to the bottom of it.
Good luck,
Richard

Audio Sync problem with iMovie/iDvd

Hi guys
I am using imovie HD6. I have been working on a project for a few months now...it runs around 20 minutes.
I exported it to idvd, burnt and watched it recently - when it was around 15 minutes long and all audio was fine.
I have since added about 5 minutes. The audio plays fine when watched on my mac in imovie - however last night I burnt it to DVD using idvd and the audio is about half a second out of sync in one of the two interviews I have in the early stages on the projects. Both interviews were made using the same video camera. An interview in the new part of the project has the same problem.
I always use the same camera and have about 3 finished projects with interviews where the audio is fine.
Can anyone suggest a way to correct this problem?
Many thanks
Ross

Like many others, the sync issue is when taking a long clip or clips to iDVD to make a disc. The movie runs fine in the iMovie preview, but slowly goes out of sync in the final iDVD version. I used a Panasonic miniDV camcorder, 16-bit sound, SP record mode. I also tried extracting the audio in iMovie, then taking it to iDVD - no help. Then I tried breaking the movie into shorter clips (still with the audio extracted), saving it as a quicktime movie, then taking it into iDVD - no help. Although the breaking into shorter clips was done after the video was already imported. So, after all of this not working, I've now scrapped all of the imported video and started over. This time I set the import preference to automatically break the video into 9-minute clips as it's being imported. I read in the forumn that that's the "true" way to break into shorter segments - not after import. I'm just now in the process of seeing if that will help matters. Any suggestions? I'm really at a loss for ideas since I did the original recording in 16-bit sound. Everything I've read seems to indicate that 12-bit sound is the main culprit with out-of-sync issues.

Weird audio sync problems with Zoom H4n?

We are adding a voice-over track to a Keynote presentation - using the inboard mic in a MacBook Pro.
We are simultaneously recording the voice-over with an Audio Technika mic plugged into a Zoom H4n - recording at 48/24.
We export the Keynote to a ProRes LT Quicktime movie - outputting the sound as 48k/24 bit
I'm not sure what Keynote is recording the original voice at (and I'm thinking that may be my problem).
I bring the ProRes LT Quicktime movie into FCP Studio and try to sync up the Zoom Audio. And it doesn't stay in sync. Here is the odd thing. When you look at the waveforms in the audio files, they are exactly in the same place ... but by the end of the 45 minutes the actual audio is WAY out, seconds out. It doesn't make sense to me that the audio waveform is identical, and the sound is delayed on the Zoom track.
Technically, the ProRes and the Zoom audio tracks are 48/24. The only unknown is what Keynote records at. I'm suspecting it's probably 44/16. Which could be my problem. But doesn't explain why the audio waveforms are identical (and on one the audio is actually delayed).
Any ideas?
all ears, Ben

Thanks for the reply. I don't have time for this. is it time to switch to a different editor?

Audio sync problems with greenscreen I have replaced the camera audio with my zoom recorder audio and it is in sync. When I apply greenscreen the audio goes out of sync. What am i doing wrong?? So frustrating..Thanks, Peter
