Then use something else ^^ :)

../..And if there's no timecode or frame rate embedded in the Iclone rendered wav file, then it will likely never match up. I guess I will have to render the audio in a video mode instead to sync the audio file into the same frame rate as my  image sequence. I'll give that a try. 

If I understand you correctly, it is not the speed at which the wav file will be played that bothers you but the placement in time of the wav file in your editing software, in regard to where you placed it in iClone, because probably your wav file does not start at frame 0 in iClone, is that correct ?

If so then the trick is to render a video file (low rez, low graphic/rendering but with the correct frame rate) with audio. You import it into your editing software. The audio will be linked to the video so you can place it anywhere in the timeline. Then render your images sequence, import it in your editing software and place it at the same time (snap?) as the video/audio clip in a second video track. Then unsync/unlink the video from the audio and delete the video clip. You then are left with your image sequence and audio clip perfectly synchronized.

Thanks, Guy.  I may have to try a different editing software, then. The smallest still duration I have is .03 in Pinnacle Studio, it can't go to a lower decimal place. There's no option I can find that will just set stills to 30 FPS, you have to set the still duration manually.

There is no "frame rate" for an audio file, only "samples rate" (44,1Khz, 48, 96, etc..) which is totally independent of your actual movie "frame rate".

Internally, iClone runs at 60fps. So all animations and lipsync work you do in iClone is done at 60 fps. Your audio file is still running in "realtime".

So it all depends of the settings of your movie editing software to get it right.
For your final movie or video, you want which fps ? Say 30 fps. Then from iClone, you set 30 fps as your image sequence rendering frame rate.
Then in your editing software you set your project to be 30 fps, import your image sequence, your audio file, the result should match.
If it doesn't, it is probably because your iClone is not playing everything in realtime or "in-sync" probably because your scene is too heavy (hence the advantage of doing animation with "light" assets).

Normally you should not bother with "still duration" as long as you indicate your editing software your image sequence should run at 30fps. But if you are asked for a specific frame duration then 30fps -> 0.333..s

Also, don't pay attention to 29.7 kind of fps, those are only timecode tricks and do not change the actual speed of your image sequence which will still run at 30fps. It only means the second unit of the timecode will be incremented/reset every 29.7 frames instead of 30 frames.

Thanks, Mtakercart. The frame rate for a wav file is not able to be changed, but that should be okay, because it shows that it is set as 30 frames. I can render the image sequence at 30 frames. However, it still doesn't match up exactly right. And weirdly, when I check the wav file timeline, it shows that 1 second =61 frames, and 2 seconds =121 frames.  So maybe it's not really set at 30 frames as it shows. 

What still duration do you use for a 30 fps rate? I have been using .03, which seems the right speed to the naked eye, but I read somewhere that 30 fps in video is actually closer to 29.7 or something along those lines. I don't know if that plays a part or not, but that would be enough to throw off the lip synch in a several second conversation.

When you set a frame rate in the export window render , you must set the same frame rate in your edit sequence.

I'd like to hear more about this, specifically how to integrate dialog into a sequence that is rendered in images. I have tried animating a conversation with lip synch in Iclone, rendering as a sequence of images, and then rendering the audio separately as a wav file. I have had inconsistent results in getting the rendered audio to match the image sequence. In some cases it is really off.  I'm thinking it may be because the frame rate is slightly different when you use images.(?) How do you set things up to deal with this?

You can use Davinci resolve :

Or Hitfilm :

Both have a free version and you can make robust editing.

Just about every available Video Editing Software package (NLE) can open/Import an image sequence for editing. Which NLE are you using?

Yeah but how to convert the png sequences to video file. 

Because i will need to edit the video (trimming, adding sounds fx etc).
