30.25 FPS

[Alberto15Romero]

I just got a new phone and strangly enough it records video at 1080p @ 30.25 fps, when I import this to Premiere @ 30fps, every second, 0.25 frames are lost, thus every 4 seconds I loose a frame which leads to audio and video sychcronization. Does anyone know what to do?

Thanks!

A frame-rate like that actually most likely indicates that it is using VFR (variable frame-rate) recording, as do most phones. So the frame-rate varies per second throughout clips. The 'average' rate will be reported as the clip's frame-rate by PrPro.

And ... you can't lose a quarter of a frame. It will either re-rate the speed slightly or occasionally dump a frame.

Oh, I see, it is quite complicated but how can I avoid the non sychronization then?

You cannot.

That is how your phone operates.

Or get a regular videocamera.

Run the file through Handbrake and set it to constant framerate if you have audio issues on the timeline.

Thanks, it is a bit of a pain in the back to have to put the video through that everytime, especially if it is a long video, but at least it works

Thanks again!!

Managed to fix it, thanks!!

The latest 2018 PrPro can work fairly well with most VFR media, but not perfectly with all phones/devices that produce it. So, when that strikes, it's still best to do as Ann suggests and use Handbrake to convert. You can batch-convert in Handbrake and say do it over-night so you don't waste time sitting there while it's converting.

I'll include my personal settings for Handbrake such that you both get it converted and keep the best file-integrity at the other end.

Note that I've red-ticks by ​both​ the radio-box Constant Framerate button ​and​ a specific number in the FPS box ... you have to have both ​a​ number and the box. The box checked and 'auto' or anything other than a number, you'll still get the original VFR out.

Also, I go with at least the 4.2 on Encoder Level, though I've played with going to 5 on occasion. But this will result in files with nearly the same or slightly higher bit-rates than the original, avoiding re-compressing at a higher rate.

With version 12.1.1 you should not have problems with those files.
