Had the same problem and basically was told my system was not good enough to cope with the files, including .mov files.
Have upgraded to an Intel i7, 3.2 6 core unlocked processor. 64GB ram, ssd 128gb cache on a 300gb Velociraptor and using a Zotan NVidia 680 4gb graphics card. Have 32gb ram as windows cache - and I still have the same problem!!!!!


Its not hardware - its the software, it just has to be!

The rendering of 2 layer videos and editing of same takes minutes now - it took hours on my last machine.

As soon as you layer tracks and music (not .mov files) is gets jerky! Impossible to sync and its frustrating.

Anyone out there with an answer? Thanks, George

George, I gave you an answer and asked you not to post the same question/information in multiple places. It is bad etiquette.
You will get more help if you stick to one thread and answer any questions that are asked. Remember we are not tech support, we are users like you who have a little more experience. It sometimes takes several replies, built on each other, to get you an answer that will cure your problem.

Your post in this thread has nothing to do with the issue that the original poster has. I actually overlooked it because of your post.
Do you have any suggestions for pmalbec1? .

Quote: I'm trying to make a music video from the Gospel group of my community.

I have the video separated from music. I have several shots from different views in different places, etc.
So, I'm trying to synchronize the lips or instruments from one shot with the main music.

And due to the lag and jumps, it is impossible to sync.

My machine is a laptos HP Pavillion dm4, i5, windows 7 Home Premium 64 bits, 8G Ram. Video Intel Integrated
PD11 Ultimate, 11.0.0.2110

I tried to increase the video mem by BIOS, but I didn't find the option.
Even decreasing the video quality in the PD preview.
Guys... I don't know waht to do, and it is very important.

Any help would be usefull

Thanks

It is almost impossible to sync video and music from several different sources. Different devices may operate slightly differently -- out of phase essentially. If you capture the video, there may be dropped frames. The tape recorder may be running slightly slow - I've seen this several times.

Does the sync start in sync and then go off sync? This is often a sign of dropped video frames. If the sync is off by a certain amount and stays that way to the end, then there is hope !

Your best bet is to work in shorter sections cutting both the video and the audio and try to sync them together. You may try to add some transitions to hide the video cuts so that they line up.

Sorry I can't be more positive. .

Hi,

Steve sorry about the multiple replies but I have to say that the problem is in PD, or at least appears to be.

I record sound from one source (the camera) and then have the event recorded professionally. This master recording is laid down on the track and I try to sync the normal sound to the video. I them mute the normal sound and leave the master source in place - in sync to lip movement. This is fairly standard practise in video editing.

As you add in tracks/effects the vies start to stutter - making it impossible to lip sync. made this public to give you an idea:

http://www.youtube.com/watch?v=WzJB0_wIUCc not a lot of transitions/effects?

Nearly impossible to lip sync as it get longer.

Thanks for any help. New hardware has made a big difference - but this is till a problem so probably not a "spec" problem but a software clash somewhere. Thanks, George

Great performance and excellent video! I guess I was so wrapped up in the music and images that I forgot to look really hard for any sync issues.

Do you have any videos where you see the sync go further off? I really didn't see any stuttering but I assume you posted something where it was no all that visible.

Now, what camcorder are you using? How are you moving the video from the camcorder to the computer? If you put the vidoe with audio on the main tracks and then add the recorded audio can you tell how far off the wave dispalys are off?

Do you thing it is possible to slightly slow or speed up the video to match the audio? Alternately can you adjust the recorded audio slight to match up? I have not used Audio Director to adjust the audio so I can't comment on that. I have used a different audio editor to make almost infinitesimal changes to audio.

Another thought entered my mind (after a glass of wine) Try outputting the video with the for a mpg or other file and then create a new project using that file and adding the effects you want. The original video will be tied to the other audio so any change you make should not create sync issues. It may be a little harder to edit though.

georgemon ,

I looked at the last minute of the video and I do not see any serious audio issues. What type of video files are you editing ?

Win 10, i7

Hi,

Sorry there is no problems in the viewable video once you render it. There is a very slight knock on effect due to the codec Youtube uses in its compression but that is hardly noticeable.

The problem is only in editing. When you start off there is not a problem so in my case the audio and lip sync blend together it is only when you start to add fades and inserts does the problem kick in. You play the video and the sound goes well but the video will lag/judder well out of sync.

I now think the problem is with sound - not video. If it was video many would have the problem and not just a few.

I have completely changed my machine (PC). Switched operating systems to Window 8, spent £1000's on hardware and still have the same problem?

Conclusion - the problem is in PD 11. Probably how it handles sound. My new system has a new 24bit sound card and system installed so not the output. I think PD 11 cannot handle multiple sound tracks? Will need to experiment a bit but I think that is where the problem lies.

My .mov files used to take nearly 2 hours to render off about 12 mins of footage. My new system does it (7 mins of footage) in 8 minutes!!! Fab stuff.

Will keep you posted. Thanks, George

georgemon ,

Please do not keep posting info that is not related to the original post by pmalbec1 . Win 10, i7

Hi,

I thought the content was very relevant to the problem being experienced by the poster. The problem seems to lie in the number of "sound" files being used in the edit.

One sound file and it appears to be OK, more than that and it does produce this juddering, out of sync problem.

Try cutting the number of sounds channels and see how he gets on?

In fact when I get a chance to run some tests I will try that theory - surely that is relevant to the problem?


Thanks, George
