I’ve been having sync issues with VFR clips lately, especially with long gameplay recordings. It’s great that the team is looking for sample files to improve the editing experience. I can help by uploading some of my problematic footage if you're still collecting data to test the new Premiere updates.

Thanks ❤

I just want to say thanks for looking in to this. 
In our facility we use a workaround where we preconform all phone footage we get to fixed 25fps before editing to remove all related issues. So I won’t be able to give any useable recent data but I’m happy it's being taken seriously and hope to see a solution that can remove our workaround.

You know what you could do, stop releasing new versions every year when they aren't ready. You could use that time to work through the years of bugs and feature requests you already have. 

Thanks for looking into this.

I can share plenty of VFR material from promotional and social media projects (mostly iphone footage), but in my experience the main issue isn't necessarily playback or export. Premiere generally handles that fine as long as everything stays inside the timeline.

Where things really fall apart is proxy generation.

With VFR footage, attempting to generate proxies always completely cripples my machine. My observations are that since the frame rate is fluctuating, Premiere struggles to lock the proxy generation to a consistent frame rate, which makes the process useless.

Interestingly, I rarely see this issue in Resolve. From what I understand, Resolve tends to conform VFR footage to a constant frame rate on import (or interpret it more predictably), which allows it to generate proxies without issues.

A possible improvement could be something like:

• Detect VFR on import

• Offer an option to conform to the closest constant frame rate (e.g. 23.976 / 25 / 30) before proxy creation

Right now my workaround is usually to transcode the footage to CFR before editing, which solves the problem but adds an extra step.

That said, part of the problem also comes from capture devices themselves. Phones and screen recordings default to VFR, but now that many devices market “professional” video features (e.g. Blackmagic Camera app), it would be great if constant frame rate recording became more standard to avoid these issues altogether.

Happy to share sample files if helpful.

hi

this may not be related to VFR but can you tell them to add shortcuts for presets (effects, transitions) plz

i did post about it but its been a year no respond

Really appreciate you reaching out to the community about this. VFR issues can definitely be frustrating, especially with phone and screen recordings, so it’s great to see the team actively working on improvements.

I’ll gather a sample project and system details and send them over via PM. Hope this helps make the VFR workflow more stable for everyone!

I’d suppose, to reproduce this notorious problem, you’d only need a really long footage from a cellphone, like an hour or two long, cut heavily. it’s normally a 99 out of 100 case of a VFR drift scenario.

I really wanna help and give you some VFR footage but since it’s always been a problem I now demand a CFR only footage from my clients or convert it to CFR.

Because there are different scenarios like zoom, OBS records. People usually don’t bother themselves with video editors’ problems and shoot as is.

Why not cbr and ditch vbr? Is it because of a great size difference? I only use cbr because vbr make transitions look like garbage.
