I have an important project on deadline. It's all done and now every time i go to render it, it crashes IMMEDIATELY. I tried separtating the video from the audio and rendering it. Nope. I tried rendering small portions. Nope.
Okay. Riddle me this. I tried to open it in PPCC 2020. It relinks to the footage incorrectly by two frames. The whole sequenc is two frames off. And some of the footage is offline, even though I haven't even touched the drives, and when i go to relink them, the program says they aren't there, even though I see that they are.
Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and your source properties and sequence settings. By any chance were any of your sources from a screen capture or a smartphone.
If so, that is why a switch from DNxHD to ProRes worked for you. If you uncheck it, then Pr will render your video on export without using any previously generated preview files, and should make your preview file codec choice irrelevant. Most importantly, your export will use your source video and not preview files, which will eliminate any possible generational degradation.
