Question

“required files rendering” Message After Simple Edits

I shot my videos using the Osmo Pocket 3 in HEVC format, 1920x1080 resolution at 29.97fps. Since the original files were quite large, I decided to transcode them using Adobe Media Encoder to H.264 with “Match Source – High Bitrate” settings to create proxy files.

 After that, I created a sequence in Premiere Pro using the encoded files. My editing was fairly simple — I sped up the clips to 150%, made some cuts, and removed unnecessary parts.

However, after each cut or speed change, I keep getting the “Render Required” message and have to wait around 10 seconds every time I play the timeline.

 This keeps interrupting the editing flow, and it feels unnecessary given the lightweight edits. Why does this keep happening, even though I’m using proxies and doing relatively simple edits? Is there a better workflow I should follow to avoid constant rendering?

both HEVC and H-264 are not great editing formats.  In both of these formats, each frame does not exist on it's own but in relation to previous and later frames which can add a great burden on premiere.   I suggest you try transcoding to an all iframe format like prores where each frame is complete.  And proresLT or Proxy are great proxy formats.   Happy to go in to more detail explaining the advantages of this workflow...

Thank you for your response. I tried transcoding the media using QuickTime – Apple ProRes 422 LT in Media Encoder, then brought it into Premiere Pro, applied speed changes with pitch preservation, but I still get the same warning message. Interestingly, after rendering that section, the audio pitch does go up, but the warning message no longer appears.

Hi @elegant_Glitter7398 - When you add a speed change to your media, Premiere Pro needs to reprocess the audio to match the new timing which is why rendering is required. This is expected behavior and ensures the audio stays in sync and maintains quality after the adjustment.

thank you for your answer !
But.... what should I do in this case? Do I have no choice but to preview and cut the entire video at normal speed? My footage is quite long, so watching it all in real-time takes a lot of time…

I really need help....

Also, I noticed that when I apply speed changes before rendering certain parts, the “Maintain Audio Pitch” seems to get disabled automatically. Is that normal behavior?

HI @elegant_Glitter7398 - Yes when you make edits in your media file then the audio will need to be re rendered that is expected behavior.

If you’re speeding up your media but don’t need the audio sped up as well, you can disable the audio clip. To do this, right-click the audio clip in your timeline and make sure “Enable” is unchecked.
