How do I make stuff play?

[Steve Zeeeee]

All i did was reverse direction a 15 sec 4k clip (Sony RX100 IV) and it just wont play.

I rendered it, no, I saved it, no, I restarted PPro, no.  My job is to have

a movie, not a still.  Thanks anyone.

What are your sequence settings?

What are you rendering the media to?

Is your project's rendering currently set to use OpenCL or Metal acceleration?

If so, if you go to File > Project Settings > General and switch the Rendering to Mercury Playback Engine Software Only, does it play or render properly?

The reason I ask is because like you, I have a Radeon 7950 in a Mac Pro tower and I've seen a problem where time reversed video won't render using GPU acceleration. Forward video works great, no problem.

The workaround has been to use software rendering. I've seen this bug come and go, and would be disappointed if it still exists or came back. I haven't used reverse video in a while so I don't know if the bug had come back or not in recent versions. But I just tried it in CC 2017, and GPU rendering of reverse video on the 7950 is currently broken for me too.

Let us know if software rendering works as a workaround.

"Mercury Playback Engine Software Only"

yes that worked thank you.  How are we supposed to know these things?

Now all the forward stuff is locked up.  Do I have to render everything

all the time to see what I'm doing?

Thanks,

[Conrad_C]

Glad it helped. As far as how we're supposed to know these things, we're not supposed to have to know these things because it shouldn't be broken in the first place. The way I found the workaround was from experience with troubleshooting video: If the problem has to do with something not displaying properly, it might be related to rendering, therefore try changing the rendering method.

When you say "forward stuff is locked up," what I would expect is that when using software rendering, it may take much longer to render each frame. If that's what you mean, then that's expected. It's why we need the graphics card acceleration to work. But if you mean nothing is happening at all, or if you mean that the forward video is now black, I'm not sure what might be causing that. When I switch to software rendering, everything works, it's just a lot slower than when I can have the 7950 render it.

now i still have to render every single touched clip

and usually the ones around it.

why isnt the sequence 4K like the original?

You said in an earlier post you shot with a Sony RX100 IV, that camera shoots UHD which is 3840 x 2160.

If you created your sequence settings by dragging or editing a source clip into an empty timeline, Premiere Pro did its best to match the sequence to the source.

yeah i dragged into the timeline like always so it would set up

the sequence in tune with the footage.  now what?>

Cuz I am going to need all 3840 for some cropping.

how does this stuff happen?

I dont want to rebuild the show.

[Steve Zeeeee]

Wait, it does show original frame size at 3800.

"What am I rendering the media to"

How do I know?
