Audio out of synch
on May 23, 2019 at 6:14:17 pm

Just shot some iPhone footage and it plays back fine on the iPhone. But when I bring it into DR, the audio is way out of synch. I shoot at 30 fps and set up the project settings accordingly. DR did not report a frame rate mismatch on import. The problem persists in both the Cut and Edit modes.

Set-up: iPhone 7, Rode VideoMic Me-L, MoviePro set to 30 fps, 48KHz, H.265, AAC

Any ideas on what's going on here?

Thanks as always

Hi

Try opening one of your recordings in the QuickTime Player and save your recording again - then try opening the recording into the Davinci Resolve !

Best,
Ole

Hi Ole

Thanks. Interesting idea, but it didn't work. I tried to relink the footage after the save from QT and also just deleted it from DR and reloaded it. No deal.

What do you think is going here?

I can see that you have set MoviePro to 30 fps - but I still think your recordings are with variable fps! You can try converting a recording to constant fps, with HandBrake! Or use the MediaInfo app - to view data of your recordings!

Bruce, I would agree with Ole, transcode to get constant frame rate. But if that doesn't help you may also want to download and install the latest v16b3.

Best Regards......George

Thanks Ole

Whatever was wrong, HandBrake fixed it. Thanks so much

My opinion is that iPhones are bad choices for video cameras. You're better off getting a real video camera (even something modest like a 5D or 7D DSLR, or perhaps a low-cost BMD camera) and then degrading it to make it "look" like a cell phone camera. You can always add an iPhone overlay to make it look like a phone -- I've done that several times in indie films.
