CC 2015 Previews Not Real Time

[Walter Soyka]

Previewing behavior in Ae CC 2015 has changed, and Ae is still not designed with real-time in mind.

Just so I can understand where you’re coming from, what did you do before on CC 2014 and what did you get when you did it, and what are you doing now on CC 2015?

Thx for the reply.
I just want to see a simple “RAM Preview”. Before, you pushed the 0 on the numbers keyboard, it renders frames into the ram cache, then when its finished it plays back in real time.
Now, it loads the frames, the line on the comp is green, but it wont play back in real time, only sometimes 4, 10, maybe 15 frames per second. Audio previews are ok. Just video doesnt work.
I understand AE is not “real-time”, I have been using it commercially for many years. But RAM Previews should be…
Adobe CC has 50 Gigs of RAM allocated, and nothing else is open. OPEN GL and CUDA are recognised by the software.
Any ideas?

Hey, the first thing i noticed after updating to 2015 was that the RAMPreview did not stop by clicking somewhere in AE (which it did before). In order to recreate your problem, i quickly generated a testscene with a lot of DOF, which usually takes a lot of time to render. As before “2015” the first run was slow, not realtime in order to render the frames into RAM. But as long as i did not change anything, it ran in realtime during the second runthrough. When i change something during RAMPreview (which was not possible before), AE needed to calculate again, resulting in a slow playback again.

Only sometimes i noticed the RamPreview not running in realtime during the second (or third) runthrough, although i did not change anything…

cheers,
kws

I got the same problem over here. my bigger problem is, when i hit the Ram-Preview key it start the preview and i am unable to abort this. i have to wait till after effects finished calculating.

Preview has changed a lot in 13.5. If you haven’t seen this already, please read this Adobe blog post:

there is a part thats called “stop a preview” that says: press pad0, space, shift + pad0 or Esc … none of these stops it. the only thing that stops the preview is clicking wildly around the time indicator in the composition panel/timeline

File a bug report. There is an update coming in July to fix these kinds of important bugs.

In the meantime, try messing with the preview settings and preferences. Some of these odd quirks have been circumvented by tweaking a setting here or there. If you find something that works, be sure to amend that to your bug report.

This forum post [link] over at the Adobe forums has a suggestion that may work.

I’m having the same problem. Realtime RAM Preview does not work 99% of the time on CC 2015. I have the latest NVIDIA drivers, 40 GB RAM, 3 GB video card, 24 core MacPro. Even with the simplest of comps it is glitchy.I can go over the same section 10 times and cannot get a realtime RAM preview (24 fps) for more than a few frames before the framerate starts dropping down. Unfortunately, the installer automatically deleted CC2104 or I would go back to using that. I had to spend about two extra hour on a project yesterday because of this bug.

For future releases of CC, remember, you can choose to NOT remove the old versions when you install new ones. See this Adobe link: https://adobe.ly/1MQ48cW

If you’ve accidentally removed your old versions and need to go back to CC 2014 until the bug fix update for CC 2015 comes out next month, check out this link for installing old versions: https://blogs.adobe.com/adobecare/2015/06/16/how-to-find-and-install-previous-version-of-adobe-apps-in-cc-2015/
