My After effect import premiere project, black screen comp

Report · Mar 23, 2021

First of all, this article uses a translator, so the context may be inaccurate.

After editing in Premiere Pro, if you use the import premiere project as an aftereffect to work with effects, the composition contains a black screen.

I'll attach some images.

It's my Premiere's timeline.
As you can see, there is no gap.

The sequence setting is 29.97/drop frame/1920*1080.

I imported the premiere project from After Effects and opened the sequence (comp).

That's a terrible result.
Some parts are out of position between less than 1f, and the worst part is 1f, resulting in a black screen. (Last photo)

These are the composition settings for After Effects.

There is no difference from Premier.

I can't understand why this problem keeps bothering me.

If someone knows how to fix it, please let me know.

Please don't tell me to connect from Premiere to After Effects via Dynamic Link.

That task makes the project too heavy and I don't like it.

Version

AFTER EFFECT : 17.7.0 (Build 45)

Premiere Pro : 14.9.0 (Build 52)

Well, all your clips have FX all over it in Premiere, which could mean that you are messing up framerates just by that. this seems liek the classical misunderstanding where you simply already moved to far ahead in Premiere and nearly finished the project instead of just leaving it a rough cut. Start by actualyl creating a version of the project with the effgects stripped down and see if it makes a difference. Likewise, double- and triple-check your footage interpretation, sequence settings and comp settings. Somewhere there could still be a misinterpretation.

Thank you for answering my question.

All videos on the timeline are time-lapse videos, so we applied speed ramping.

Other than that, nothing else worked.

Speed ramping was applied up to 600% as little as 600% and as much as 800% with ctrl+r.

Could this be a problem?

It was confirmed that the sequence and comp settings and frame settings are all the same.

You answered your own question: You cannot use speed ramps in premiere and then expect everything to line up perfectly in AE. From normal quantization issues to simple differences in the algorithms it is inevitable that slight variations creep in. you have to make up your mind where you actually want to do the speed-up. Otherwise you will have to render the Premiere timeline to an actual clip to bake in your existing speed ramps.

Thank you.
So, as you say, if you want to use speed ramping, you have to choose between After Effects or Premiere.

It sounds like you have to first render the clip (sequence) to which the effect is applied to use speed ramping in Premiere and then import it into After Effects to work, is it correct?

If it were that way, it would be very cumbersome in situations where you need to modify the video.
