There are a few reasons to change the codec for video preview files.
AVI Warning: Are you getting an Error Compiling Movie warning dialog box concerning AVI files? If so, you need to change the codec for video preview files. It was somehow reset to AVI as your default video preview codec. Consider creating a sequence preset to avoid this issue in Premiere Pro 22.5.
Smart Rendering: When rendering effects in particular codecs, you can harness these video preview files to give you faster export speeds at a high quality. More info here.
Quality: Certain codecs are of the highest quality, while others offer draft quality.
Performance: Some codecs render faster if you need to render as you work. Others give you better timeline playback performance once an effect is rendered.
Here's how to change the codec.
Go to the User Guide and scroll down to the section "Change Sequence Settings." This guide provides step-by-step instructions, as well.
Set the Editing Mode (top of the dialog box) to Custom (scroll up the menu, it's at the top). The settings for video previews are then "unlocked."
Choose your codec: I-Frame MPEG (the previous default), GoPro Cineform, or QuickTime in the Sequence Settings dialog box under Video Previews > Preview File Format.
I recommend QuickTime > ProRes LT for the codec, which will provide smooth playback and an option for faster rendering, called smart rendering. The community seems to be finding I-Frame MPEG working OK too.
Click OK. The box closes, and you can render effects in the new codec.
After the export, don't forget to choose Sequence > Delete Render files to restore drive space. You won't need the files anymore.

having issues exporting anything our of premiere pro. I tried this and it got me farther than I had been before but still gets stuck exporting out. I can export small clips, a few seconds, but trying to export a minute video and it is getting stuck. It happens directly from premiere and also using media encoder. The weird thing is, if I import the premiere pro project into after effects and render it from there, it works, but the audio quality comes out poor.
|What I have done so far:
Ensured drivers up to date.
rending in to out before export (gets stuck rendering into out)
delete media cache
Computer specs are NUC with i7 processor and 32 gigs of ram and INTEl UHD graphics and upgraded to Windows 11.
Do you know what the issue might be? Thanks in advance.
Sorry. I wouldn't say I like to make assumptions, but, usually, it's non-performant media causing most of the issues. If the clips are video game streams or from mobile phones, you need to convert the video using something like Handbrake or Shutter Encoder (which I prefer) before editing. I like converting media in Shutter Encoder because it's free, and you can convert to ProRes LT, an excellent editing codec.
