Question

Proxy slightly out of sync with original

Hi, when creating proxies, I noticed that after toggling the proxy button the footage is always 1 or 2 frames out of sync with the original.

Is there a way of manually tweaking this? Say, adding an offset when ingesting or something

Using Premiere 12.1.0 on a mac

Thanks

Just came here becasue I was having a similar issue.

 

Created Proxies and they weren't syncing up with the actual footage when I toggled in the program monitor.

 

I have just solved my issue, maybe it will solve yours.

 

I had created my proxies on 50fps footage. I'd then Time Interoplated it to 25fps whilst dropping it onto the timeline, turn proxies on and footage was out of sync.

 

Instead of Inteptiting your footage, use Spwed & Duration to correct your fps and ripple edit in the menu, that way your proxies stay in sync.

 

Sorry if this seems a bit obvious

Your proxy FPS probably does not match your source. Manually create a proxy preset in Media Encoder and recreate your proxies.

Thanks for your reply. I've tried creating proxies numerous ways: Internally in Premiere, Media Encoder and using FFMPEG in terminal. They rarely match.

Here are the specs of the movs, the only real difference is bitrate;

Right click the clip in your project, choose Proxy - Create Proxies.

Select this option:

Let Media Encoder do it's thing. Toggle proxies. Are they out of sync?

I ask because I've make a ton of proxies and I've never seen them get out of sync.I'm trying to make sure your proxies match the ratio of your footage as a mismatch will add pillar boxing which can be misidentified as out of sync.
