Hey guys. So in my project file I have a lot of looping footage, which I achieved by using time reversed layers. I started the project file in a trial version of CS5.5 last week, but upgraded to Creative Cloud yesterday. Since moving to CC I noticed that all my time reversed layers have missing frames at the beginning of the layer, causing a blinking effect on my footage. In the final comps those layers will flicker out, showing the images and backgrounds beneath them both within AE and in the final comps when I render them to an .mov. I'm wondering if anyone else has run into this bug and knows of a way to fix it. I've nudged my layers around a bit, but regardless of when the layer starts or from which point it begins sampling my footage, the first frame of the time reversed layers are blank.
Here's some information that might be helpful:
The compositions are 1280x720, square pixel aspect ratio. Starting timecode of 0:00:00:00 on all comps. The footage type is h.264 with a framerate of 23.976, the same framerate as the comps. My footage interpretation is premultiplied for Alpha, set to use the framerate from file, starting timecode of 0:00:00:00, and with seperate fields off and remove pulldown off.
The specific version of After Effects CC is 220.127.116.114. My computer information is Mac OSX version 10.8.3. 3.,4 GHz Intel Core i7. 16 GB RAM, 1600 MHz DDR3.
Thanks in adcvance guys. I could really use some insight in answering my question.
A screenshot of your timeline would be helpful. I have not checked this myself but you may have some shifted in points.
Also, just an FYI, h.264 footage, unless it's original footage from a camera, is entirely unsuitable in a production pipeline. If the footage is original footage from a camera then in most cases you can use it without modification.
What happens if you create a new composition from your existing footage and then time reverse the footage?
Dèja-Vu? I read and replied to such a question recently.... Anyway, since you use the embedded timecode, have you triued turning it off and enforcing your own? Since AE works on proper time calculations, even minute discrepancies might throw off things... Also check the comp's shutter phase settings...
Yeah, I'm pretty sure that was you on the VCP forums too. Small world. Could you explain how to turn off the timecode to enforce my own? I'm not sure which menu to go to for that. The composition's shutter phase settings are 0 degrees. The shutter angle is 350. 16 samples per frame and an adaptive sample limit of 128 if that helps at all.
Yeah. We're hoping to move everything to a better video format once we get a better network that can handle that quickly, so for now we're using h.264. In case you're wondering, the same problem happens with other video formats too. Creating a new composition and time reversing it gives me the same problem. Here's a screenshot like you asked for:
My timeline's zoomed in as far as it goes. Even though my cursor's at the intersection of the two layers, the time reversed layer, which is a pair of eyes above the mouth, shows up blank and there's no eyes. Any thoughts?
Yes, this is a bug.
> Creating a new composition and time reversing it gives me the same problem.
What about if you turn on the Preserve Frame Rate When Nested Or In Render Queue preference? Does the problem go away for nested compositions then?
That works fine. No missing frames or anything. I've been using this method all day as my temporary solution for now, since time reversing my layers goes by quicker, but I'm happy to say I haven't seen any problems doing it this way.
