Question

Playback problem and preview stuck when editing bigger video files

So I am having a problem that I can not for the life of me figure out. Here is a video displaying the problem: https://youtu.be/LNoKOmhfpkQ

 

This happens when I am editing larger video files. Whenever I tab out of Premiere (to grab files ect.) it is like the program needs to reload the video file and the playback and preview window gets stuck for a long time. After a while it starts working and it will continue to work fine until I tab back out. Sometimes the playback gets stuck whenever I am editing as well, but not nearly as often. Tabbing makes the playback get stuck pretty much every time. The rest of the program is working fine. I can move items on the timeline, make edits, open menus, it is just the playback that is not working. The file in this specific example was a 161 GB, 9 hour mp4 video recorded with OBS.

I have tried using proxy files, clearing cache files, reinstalling Premiere, as well as changing settings around without any luck. I was not able to find anything helpful online either that fixed my problem. I recently started using Premire (previously I used Sony Vegas Pro...) and this is a big problem for me as it slows everything down and really takes me out of my workflow. Any help on this would be greatly appreciated!

 

These are my specs:

R9 5950X

RTX 3080TI 12GB

3200 MHZ 64GB

WD Black SN850 2TB M.2 SSD

To follow up on Phillip's excellent comments, in OBS I always record directly to mp4. As that does get a CFR rate ... constant frame rate.

 

And again ... a single nine-hour file is a HUMONGOUS data mosh to work with. And with 12 audio tracks ... that adds a load also. Huh.

    I will try recording directly to MP4 and use the time splitting function to se if this helps. Thanks for the reply!

      Recording super long clips like that definitely complicates workflows and makes troubleshooting more difficult.  

      When you record with OBS do you Remux? Or are you recording directly into the container that you use in Premiere? I ask because a popular method for recording with OBS is to go into an MKV container and then remux to MP4, but this introduces Variable Framerate, which is like poison for editing software. So that would potentially have a major impact across a 9 hour clip.  

      I don't work with them often, but in general I've also noticed that OBS clips tend to be a bit clunky, have media pending issues, etc. The media you work with and how it's encoded have pretty significant impacts on performance. Circling back to the 9 hour thing, it just makes it more difficult to adjust anything if you have to transcode and wait for 9 hours in one batch to successfully complete, versus having many smaller clips to work with.

        I do use MKV and remuxing for my recordings. The reason for the long videos is that I stream and record at the same time, often going for many hours at a time, and I like to upload my streams to YouTube, using Premiere to add intros and taking out the music track for copyright purposes. I will try to record directly to MP4 and use timesplitting to deal with the long files to see if this helps, however I am scared to lose footage if OBS were to crash while recording in MP4.

        Use the TS container. You will have the same perks as the MKV container but it will be directly supported in Premiere.  

        It's possible that removing the Remux, and subsequently VFR, from the equation will help in and of itself, but again I still find OBS clips to be a bit clunky and slow to load. If you do want to split them up you can use something like Lossless Cut.

        While you can tab out to Explorer/Finder to grab files, that's not an oft-recommended workflow in Premiere.

         

        The Project panel has import functions ... right-click in a bin, Import ... and you get the Finder or Explorer window to navigate to/select files.

         

        Or ... perhaps for your workflow, better ... the MediaBrowser panel. Which is an internal 'Explorer/Finder' panel, with favorites and all. You can simply bop into the MB panel, select/import something. No different than Explorer or Finder ... but ... you won't get this odd behavior.

         

        Working with single files that are nine hours long though will be an incredible load for the app, just saying.
