I imported a .ts video format into my project, and after rendering the clip, started working on it. I made various cuts, moved around the audio and video, and then exported it.

However, the exported video didn't match the edited clip on my timeline. Different clips ended up getting exported instead.

The length of the clip remained the same, but certain shots that I didn't use ended up appearing in my exported video and replaced shots I did use.

This happened even after I restarted the program, created a new sequence and even a new project. I even restarted my system, but the error kept getting repeated.

I eventually converted the .ts clip into a .mp4 clip, and that finally resolved the issue.
But I ended up wasting over a day trying to figure it out.

I have a problem with Adobe Premiere since the v13.1 update.

It interprets video levels incorrectly, not being consistent with interpreting video as Limited Range 16-235 or Full Range 0-255, depending on the codec.

This is making it impossible to do any reliable colour correction work with Lumetri and also is making it impossible to generate reliable DCPs as the video levels are way off.

It will either add too much crush or flatten the image depending on the source. Sometimes affecting different clips differently depending on which codecs with which flags are in the timeline

If there was a feature to manually adjust the way the video is interpreted (Full Range versus Limited Range) in the "interpret footage" for example, and also in the timeline, and on export, this would entirely solve the issue as I could manually control how it is being interpreted.

If I remember correctly, there used to be an "auto" or "data" checkbox when exporting video, which went away several versions ago. A return of this checkbox for export, in addition to the ability to override the existing metadata flags via Interpreting Footage, would solve all of my problems as far as I am aware.

The inability to do this is affecting my ability to make reliable DCPs and also is forcing me to return back to using DaVinci Resolve for any and all colour work.

My iPhone Xs Max footage plays back in Premiere Pro very gltichy and is unusable. Using a third party app such as "Hand Break" to make the frame rate constant instead of variable will make the footage not glitchy. However, it is a very time consuming process to do that for each video clip you want to use, and most of the time you are wokring with lots of video files. If Adobe could please somehow fix this problem that would be amazing. Have edited previous iPhone footage before from later model iPhones and never had this problem. Maybe it has something to do with h.265? Anyways, that would be awesome if this issue was solved! Thanks.

PPro is recognizing my footage as Variable Frame Rate (see this in footage properties).

...however unlike other Variable Frame Rate clips shot in H264, I'm NOT shown a Variable Frame Rate Mode for this HEVC clip.

I have test-clips here...

...including "thru MediaEncoder" showing the short clips appearing in-sync and long (2042) clip going out-of-sync.

But the best sample is the big one...

...on my PC playing the raw footage starts skipping around visually throughout (mostly showing first few seconds) and is obviously out of sync by 13 seconds.

I don't expect perfect in-sync on my PC, but I can't even edit with it... there's no amount of time that will resolve a frame in the middle of the timeline correctly. Not even a bit out-of-sync, it just repeats frames from start of clip.

I've received help in the forum...

"My machine is more powerfull then yours but it cannot handle the 2042 clip; ... Does not play, stuck on first frame, audio runs."

...that is my exact experience too.

For now I've used Handbrake to transcode to 1080P H264. (Handbrake and VLC can interpret the clip fine.)

It seems PPro supports HEVC and PPro supports VFR... could PPro please support both in combination?

Why there is no high quality H.264 encoder within Premiere/MediaEncoder?

x264 provides much better quality at same or even lower bitrates.
This would make it much easier for encoding to webservices without losing so much quality and using so much bandwidth.

This is must if you are directly sharing files from ME to your website. Almost every proper videohosting site (Netflix, YouTube, Vimeo etc) encodes their H.264 complaint videos with x264

If you are going to add this encoder, please make sure it actually is to specs according to H.264 standards.

If you want easy way to see difference, just put ProRes HQ video to Handbrake and play with settings, you will notice.
