P: Nested sequence time remapping bug

I've been facing this recurring issue in Adobe Premiere Pro: When I place a nested sequence into my main sequence and speed ramp (Time Remapping), upon playback, the speed-ramped nest plays for the first few frames and then displays as a black screen. Is there a way to solve this?

I have looked through the forum and seen answers like the 'nest needing more frames.' That, however, does not seem to be the issue in this case, as the nested sequence contains a longer duration of footage (therefore more frames) than I need in this section of the speed ramp. 

I thought maybe I could solve it by switching the video/playback renderer but that option is greyed out for me (it would be good to know why that is, too.)

I'm using Premiere Pro 25.1 on an Apple Mac Mini M2 Pro chip with 32GB memory. 

Any suggestions, help or advice would be greatly appreciated. Thank you!

Well they did update the status to acknowledged. Whatever that means.

How is this not fixed yet, have adobe acknowledged an issue yet. Its nearly 2025 guys. This was 8 years ago

Updating Status

How is this still not resolved?!?!

Good idea. That's what I usually do, as well.

The files are 60fps 4k directily from iphone, and reads as .mov in Premiere.

As it turns out, my additional nest failed. I ended up just rendering out that nested sequence as ProRes and dropped it back into timeline. No issue so far.

Thanks for the note. That's a little weird, but it's good to know, @jmohan00. I'm always suspicious of Xeon-based Macs. They were only out for one rev and may not have the goods you need for specific formats. For example, are you using H.264 or HEVC? I cannot verify if the CPU has Quick Sync, which is crucial for video processing in that format, especially when compositing or creating video effects.

See if changing to an editing codec like ProRes might perform as expected. Hope to hear back from you soon!

Take Care,

Hello Kevin, thnks for responding...

I am working with 4k 60fps videos.
The unexpected solution was to nest 1 final time (the final nest is 3 deep)

Bit bizzare , or my inexperiece with editing (vfx artist). or a bit of both.
I'm on Mac.

Hi @jmohan00,

Thanks for the note. What are the system and media specs? What about the size of the sequence and nested sequences? Are they oversized? Do you have scaling going on, as well? You might be out of VRAM. We need more info, please. See, How do I write a bug report?

Thanks,
Kevin
