MacBook Pro v. MacBook - FPS and Voice Sync Problems

Hi all:

I started my animation project on my 12" MacBook and am finishing it on my brand new 2017 MacBook Pro. All the layers, including sound layers, are where they are supposed to be. When I was on my MacBook (non-Pro) it was only rendering at 9 FPS, despite being set to 30, but in either case, the fully rendered version, exported to a .mov file was fine and ran at 30 FPS. Now that I am using my MacBook Pro and it runs and renders at 30 FPS, the sound does not sync with the video.

As I said, all the frames are where they were and should be in the presentation. Still renders fine on my macBook. But when I use my MacBook Pro, the video renders perfectly. The sound is wayyyyyyy ahead of where it is supposed to be though and outpaces the frames.

Any ideas?

Thx.

so yes this a normal problem. Your new computer is VERY Fast so it can easily redraw all the graphics in your animation.

The way around this is to Stream your audio, except this is not supported in WebGL and HTML5 Canvas Documents.

Colin Holgate seemed to have a solution that worked! ... check it out!

Animate CC (HTML5 Canvas) timeline is not syncing with audio

hope that helps!

That solution is for HTML5 Canvas, and if you're animating for video you would want to be using AS3 anyway.

Assuming the FLA is AS3 the sound should be set to Stream, and then scrubbing the timeline should play the right animation to go with the audio at that point. If the audio was set to Event, and was working ok when playing in the timeline on the slower machine, I would expect the exported MOV to have bad sync, that would match what you get in the timeline on the faster machine.

Thanks for helping guys. Still no luck. Animate is encodes it in Media Encoder as a .mp4 but I believe first it must be converted to a .mov file. Is there a way to bypass converting it to a .mov?

Not sure about AS3. They're .wav files--I believe the only file type that can be imported? Should I have them re-incoded?

This may or may not help... I learned this trick from my friend Colin Holgate

If you take a silent bit of audio the length of your film, the audio will stay in sync.

Yea, that's why I'm holding off on the background music. The problem is, it's a speech that is synced with an animated character.

It's the difference between this:

(The static at the beginning wasn't intended to go on that long, but it did only because I hadn't finished the levels. The static is working now)

And this:

The car horns going off while she is talking and the fact she starts talking early is something that began when rendering on my MacBook Pro.

The project is set to render at 30 FPS, it's just the 12" MacBook couldn't play it at authorship time that quickly. When rendering it as a .mov or encoded as an .mp4, it played fine. Now that its playing at runtime at 30 FPS, it's not syncing. The sound is just running way before the rest of the frames when they're where they should be.

I suppose I could try reinserting the sound with my MacBook Pro and see whether it spread the audio over the duration the 12" MacBook could render it at authorship time is the problem, but it shouldn't matter because once it's a .mov or mp4, frame rate is universal.
