P: Nested sequence time remapping bug

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,
Kevin

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

Bizzare workflow bug.
A clip : Stabilized > then nested > then Time Remapped> then nested > then Transformed.....
Goes black.

I am not familar with "SubSequences" yet.

Please correct me if my workflow is incorrect.

Same problem here, it is the same in all Premiere versions I had 😞

Hello @Águia Films,

Thanks for your video and bug report. The team is aware of the issue, has a repro case, and is working on a fix. I'm hoping we see this fix in the application soon.

Thank You,
Kevin

Hello, @andreask85831847,

Thanks for the response on this issue. I have asked the team about the issue and why it is persisting, and I will let you know what they say. Sorry for the frustration; only trying to help here.

Thanks,

Kevin

This problem is persisting for years. Nobody at Adobe cared, because bells and whistles are the hot stuff.

Now the "product team" asks the "support team" to "triage" old bug reports.

Is this a joke?!

@Kevin-Monahan AS @jmvdigital said

Add a few clips together in a nested sequence. Place said nested sequence on a timeline. Use keyframe within timeline to adjust speed ramp... notice how the footage disapears (black frame) randomly depending on speed ramp keyframe settings.

or as I said back in the mists of time

1. take a nested sequence, insert it onto timeline.

2. Double click on that nested sequence

3. Add another layer say halfway through that nested sequence, 

4. Go back to your timeline and apply time remmapping (eg>300)

Result:

Sequence will go black before it reaches the end of the sequence. This vid below demonstrates that it is not the normal behavior of a time remmapped clip.  Most of the time when I encounter this bug it is when the original footage is not the same res as the final sequence.
