Premiere renders stuff out differently to what is on the timeline

Premiere renders out the wrong section of the clip to what is actually on the timeline. It's doing this roughly 25% of the time. Possibly related to changing the framerate of footage. It looks like the clip use the new framerate of the file on the timeline but when it comes to rendering, it uses the original framerate. It's very intermitent. Issue could also be related to outputting via Media Encoder as I don't think I've seen this happen yet when exporting directly from Prem.

Another issue which could be related is recently I opened up an older project in the latest version of Prem and all the video files had defaulted back to their original framerate.

Still not fixed in 22.2.0

 

Rendered a sequenc via Encoder and it rendered something different to what was on my timeline. Re-rendered via direct Export and was correct.

by an chance does the source material come from a smartphone or a screen capture?  If so, the problem may be that your source has a variable frame rate which can cause unpredictable and intermittent issues.  Here's how to diagnose and fix the problem


use mediainfo to determine whether your source is variable or constant frame rate
https://mediaarea.net/en/MediaInfo/Download
if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum
https://handbrake.fr
and here's a tutorial on how to use handbrake

as far as your issue with the frame rate reverting, I'd suggest that you continue working in the earlier version of premiere as a workaround

Still an issue in v22.5 Exporting via encoder is just a no-go for me as I can't trust it anymore. Having to export timelines one by one is painful. Any chance you devs want to fix this bug that you have implemented??

I'm guessing this is an issue caused by the "interpret footage" to change the frame rate.   I seem to remember there were some posts here about similar problems with, if I remember correctly, an alternate workflow.   do some searching here or perhaps someone else will remember better than I do.  I also think there may be some 3rd party tools to alter the frame rate as desired.   Apple used to have something called cinematools that was part of finalcutpro studio that would do this for certain formats but they broke that many years ago.   Just working on my first cup of coffee today in NY so I may have an epiphany once the caffeine kicks in.  ah, caffeine is starting to work.  What format (codec) are your source files.  mpeg formats like mp4, etc in which every frame is not discreet may be the problem... transcoding to an all i-frame format like prores might solve the problem

I shouldn't have to use 3rd party tools. There was no issue a few versions ago and the exports directly from Premiere are fine - it only seems to be when exporting via Encoder. 99% of my footage is ProRes 422 movs. They are mastered TVCs at 23.98fps which I interpret to 25fps for UK broadcast. I've had the same workflow for years, this bug has only come about recently.

I recommend starting Pr from a shortcut (Start Menu, Desktop, Taskbar) and then once you are at the welcome screen, go to preferences>media cache and delete all your cache files. With the version changes that the project has gone through there may be stuff lingering around that is affecting the frame rate processing.

can't argue with you about what should be...  just trying to suggest possible workarounds to get you over the hump...  Have you reported the bug?   Can't count on Adobe engineers picking up the problem from this forum...  Don't have the link at hand, but a quick search here should find it...      Also, there have been a few things suggested in this thread.  Please let us know that you've tried them.  Not always easy to help people remotely unless we work in a systematic fashion...

If you're interested in a workaround, https://www.digitalrebellion.com/promedia

has an app called qt edit that will change the frame rate for you...  I think there's a free trial, so you might give it a shot...

Still happening in 22.6.2. Why the — has this not been fixed yet? Time and time again I am looking like a complete — in front of my clients because they are being supplied with edits full of completely random edits. All I am asking for is Encoder to encode what I am seeing on the timeline. It's a fairly basic ask of any NLE. Sort this — out.

Have you done a bug report?  Have you tried smart rendering?  

https://community.adobe.com/t5/premiere-pro-discussions/faq-what-is-smart-rendering/td-p/10648488

Have you tried any of the suggestions and workarounds in this thread?  Clearly most people are not experiencing this issue and it's just not realistic to expect adobe to test their software on every possible variation of operating system, hardware and media type...  This is true of every piece of editing software out there....  If you want to properly troubleshoot this problem, post back and we'll start and try and figure out what's going on in a systematic fashion.
