Changing to constant frame rate in Handbrake worked great. Thank you!

Hi Vidya,

I have the same issues. the audio is sync at the beginning and then starts to go out of sync drasticly.

It's material from a Sony a7s (mp4, AVC Coding 3840x2160) and the audio was recoded separately and is mp3 now.

Project is 48KHz as the mp3. Video is 25p as the project.

Editing the Sony material since two year and never had these issues. Last time I had it in Final Cut Pro.

Do you have an idea?

Thanks

Florian

I'm having the same issue. When I play my video outside of premiere it's fine. When I import it, the audio and video are out of sync. The file is 1920x1080, 44khz, mp4, 192kbps bit rate.

Hi Florian czar de, jes,

I am really sorry for late response. It happens when the Video/Audio is recorded in variable frame rate.

Just for a test, Please transcode the files in https://handbrake.fr/  to constant frame rate & test again.

Thanks,

Vidya Sagar.

I'm downloading Handbrake now to see if it will work. Long term having to transcode these videos before I edit them isn't a workable solution. Is Premier working on a fix for this? It's my understanding that Final Cut doesn't have this issue.

I guess the project was corrupt in a way. I created a new one and now it is all fine.

The mp4 files are from a Sony Alpha 7s and they normally work perfect in Premiere.

I moved from FCP7 to Premiere because I did want to convert mp4 to mov anymore.

Thanks anyway.

That's always a good troubleshooting option, testing in a new sequence/project.

I used handbrake on the file I was editing and it worked. I've been doing some digging and I think I've figured out the problem. My church switched streaming services recently and the new one has an "adaptive frame rate" option. I started having problems with syncing right around the time we starting using that option.

Hi Jes,

See if the device has a constant frame rate option.

As I understand it, FCP X does transcode variable frame rate video in the background (and why transcoding in QuickTime is an alternative to Handbrake if you're on Mac), so the issue is minimized and is not in the foreground for the customer. That's pretty slick. If you'd like to see something similar in Premiere Pro, give us a request here.

Thanks,
Kevin

This response from Adobe is a little disheartening.  It is not solely because of the variable framerate.  The better answer is that Premiere Pro can't handle a variable file and the developers haven't spent time on it because the market is so small.  The pros don't use software that records footage like this therefore why would Adobe cater to such a small audience that does.  Even though our audience is growing I don't believe we are a priority. 

I am very interested in hearing of a better option.  Should we use a higher end graphics card to record footage.  Shadowplay is becoming so mainstream but it's the choke point between recording and using PP. And using a 3rd party software like Handbrake is just not an acceptable answer in order to use a product we pay high dollar to use.  Even using Handbrake causes PP to have issues.  I've re-encoded 20 different presets combinations and PP isn't able to preview (scrub) these very well either.  After using handbrake you'll notice your CPU usage start to max while scrubbing and the preview will stutter.  Even when using a scratch disk opposite of the OS and it being an fast M2 SSD from Intel. 

I am guessing it has something to do in their conforming process during import.  Ever notice that when you import your footage PP conforms the file.  Link below explains this audio .  This is why the footage is different when you listen to it inside of PP and you don't when you preview it outside of PP.  This is the only thing that influenced your file.  This audio/video sync debate has been going on now for many many years.  Just google and you'll see what I mean.  When the market becomes large enough Adobe will step in and provide us an option inside their application. The only other choice until then is to use a different Editing software.  Sony Vegas I was reading the other day does have a sync option within their application.

Hi ToddyPkc,

You might try your screen captures with OBS, which can capture at a constant frame rate and will import into Premiere Pro without sync drift. Please try it.

Thanks,
Kevin

I had a client record a video on her iphone and I edited in Premier pro. I am great at graphics, but the tech stuff is a little confusing. Would her iphone have the variable frame rate that is causing the problem? She did 4 videos. 2 are bad, 2 are ok. Any tips?

Hi CrisG,

Would her iphone have the variable frame rate that is causing the problem?

Yes, especially in low light conditions.

Any tips?

Transcode the problematic video footage in QuickTime or Handbrake. See if that works once reimported to Premiere Pro. In the future, have her shoot with the app "Filmic Pro." On the iPhone that has generated constant frame rate clips as long as they are less

In the future, have her shoot with the app "Filmic Pro." On the iPhone that has generated constant frame rate clips as long as they are less than a minute or two in length and the bit rate is not too high. Hope that helps.

Thanks,
Kevin

That was a crazy fast response! Thanks!! Her videos are more like 5-7 mins long. I am not sure why she didn't use her computer. What should she do (program or app) for long videos on phone or computer?

I think you can shoot 5 minute clips in the iPhone with FilmicPro in HD. Do a test. I start breaking down with longer clips and shooting 4K. Personally, I tried to shoot a doc on my iPhone and am giving up on that idea as it's not reliable enough for sync, long takes, 4K recording, and not enough features. I am buying a 4K camcorder as a more reliable means of recording video.

Cheers,

Kevin

seems like adobe premiere should make it easier just to import nay footage from a iPhone.

Im having the same problem and reading all these post is very confusing. 

So what I am hearing is. Don't should social vids on your iPhone?

Guess I will go back to final cut pro that doesn't have this problem at all

Correction.  Don't shoot anything you want to edit on your phone.

Or to be totally safe, you can also just go with - Don't shoot anything on your phone.

I agree with you. Please make a feature request.

I use one. However, I shoot with Filmic Pro, not the native camera app. No trouble for short videos.

Guess I will go back to final cut pro that doesn't have this problem at all

That is certainly an option for you. Their encoders currently can transcode this footage.

Thanks,
Kevin
