This issue started out of nowhere for what I consider to be no reason. Working on average sized 720p compositions with modest animations.
I am running fresh comps in AE CC with absolutely no plugins, freshly purged memory, cleaned cache, restarted comp, no other applications running on computer and 13 gb of memory allocated to AE... etc.
"After Effects error: RAM Preview needs 2 or more frames to playback."And I have searched this entire forum about a solution but nothing worked.I have been in Preferences-> Memory & Multiprocessing and adjustet the settings.
I have tried PURGE all memory. Uninstalled After Effects CS6. Installed again with update 11.0.3.6 .....and still the problem occurs? I have fought with this error since I installed After Effects CS6. As you can see my computer have enough RAM and CPU power.
I'm running into a problem whenever I use multi frame rendering in the ram preview. If the machine is rendering and I don't have After Effects as the active application or whenever I stop playback of the ram preview, the cached frames are immediately deleted. I can see the green line moving forward as the image is rendered, but the second I stop the preview (or if AE is rendering in the background and I don't click back to it in time for it to begin playback) then the frames are gone and the green line disappears and I cannot scrub through the rendered frames.
If I disable multi frame rendering, then the green line and the cached frames remain in the preview window, and I can scrub through them like normal; they do not clear. Only when multi frame rendering is enabled does it disappear after render.
I know the frames are saving, because I have 32 GB set on my SSD for the disk cache (I also put them on an external HDD to test with the same results). It will fill up that 32GB of space presumably with the cached frames that disappear after render, but they are not accessible. I also have 16GB of ram, with plenty free for AE to use for caching (3GB per core = 12GB set for AE ram preview). I have not had this problem of the frames clearing until AE CC.
The only thing I can think that would be different from other times when I've not had this problem is that I'm using ProRes 422 (LT) clips in the compositions. But I don't know why they would cache normally without multiframe and then be immediately deleted with it enabled.
And no, rendering without multiframe is not an option. RAM previews take four times as long with single frame rendering, and I don't want to sit at my computer all day waiting for previews. This is extremely frusterating, as I must have AE open as the foremost program at all times. If I miss that crucial moment where the render completes and click back to the program a second late, all the frames are gone and I must rerender again! It happened twice while writing this message.
So what's the deal?

I have a Comp, which admittidely is a render nightmare, with 64 instances of a the same video each 1 frame ahead of the next. So it's very RAM hungry and something of a balancing act between the number of CPUs and how much RAM each is allowed (but generally allowing 3GB per process and 1 less CPU than suggested)
The thing that is killing me though is the RAM Preview is going almost 3x faster than a normal render. Even when the normal render destination is an SSD and compression is None. otherwise exact same settings i.e. 100%, best quality.
The really interesting part is that when doing a MP RAM preview the CPU usage (as viewed in activity monitor) is a solid wall of green but when I do a standard MP render the CPU useage is fluctuating wildly. I've tried various dififerent MP options (all maintaining a safe RAM overhead for the sysytem) with very little difference in performance.

I'm following some tutorials on digital tutors and I see that an easy way to preview the frames is just by simply moving the time indicator, and the frames will play in real time by just moving the current-time indicator back and forth.
However, it doesn't work for me for some reason, when I move my current time idncator, the only thing see is the frame what it was on, and won't update until I let go of time time indicator.
I am working on a motion graphic, it contains a background a camrea and a couple 3d layers, when a I render it it a 2 of the 3d layers shake randomly. This does not happen in the preview. Using CS4

and I can fin nothing about this error anywhere on line.
I just started using the new x4 version of VS and I noticed the playback on the preview window is very choppy. I have Pinnacle Studio HD, Sony Vegas Pro & of course Premiere CS5 installed to compare between them all, and don't have that problem, even with effects or anything added. Is there an option somewhere I'm missing? I've tried different video types and it doesn't seem to matter. The main one I'm trying is a 1280x720 AVI file I recorded.
Checked and unchecked the "Hardware Acceleration" ticks, no difference either way.
Checked DirectX....up to date.
Checked graphics drivers...up to date.
I'm trying to edit a set of titles made in Premiere in After Effects, and after I import the file (as a Premiere file) then load the sequence into the timeline; the preview is just a black screen throughout the entire preview. The titles never show up.
View 2 Replies View RelatedOnly after this occurred a second time did I realize there was an issue with the rendering.
I rendered frames 600-1500 on the machine with max 2014. The renderer indicated that all frames were rendered in the usual way. However, upon playback (avi), the animation lasted 18 seconds rather than the expected 30, with the last 12 seconds (about 360 frames) missing.
This happened for the first time a couple of days ago using the same project file. In both cases, the avi file size was 1,044, 391 KB. It is not unusual for other project avi files to greatly exceed this. I have looked in the project file for some parameter that set an avi file size limit without success.

The videos were from Fuji X100, Nikon D7000, Sony NEX-7. No matter how many different phrases I google, I could not find any info on this issue. This is a bug that needs to be fixed ASAP unless Adobe is giving up on video in LR.

I've looked everywhere online for tutorials but still don't understand how to do it. I keep getting 29.97fps in the end. I need it for a project and I need it very soon.I use MP4 video files at 60fps.
View 10 Replies View RelatedI render 36 frames from different angles to PNG files on 3Ds Max 2013 but now I want to hide a model and make it so all the parts its blocking to also become transparent.
If you don't understand what I mean I don't want to simply "hide" the instance because then all the parts in the back that otherwise would be invisible would become visible, I just want those parts to become transparent as if I "subtract" the image of the hidden instance out of the final render image.
Like the 3d model is invisible but erases anything behind it.
Edited my footage in a sequence in normal size.
I wanted to make it widescreen, so I made a new sequence in 1920x810.
I then copy pasted my edit into the new sequence and started rendering.
The render window kept adding frames to render, and the percentage jumps and very slowly adds 0.1% into the progress.
I tried choosing a smaller amount to render, same problem still persists.
Why does it now want to render normally? Why does it add frames to render all the time?
I am having trouble figuring out how to get my particle system to render past 100 frames. I have my scene set to 600 frames, but after 100 the particles disappear. I am not sure what is going on.

but absolutely out of control.We are desperated, because deadline project is coming to the end..We work in Smoke around 85% and is a 90 minutes film. Is a huge project..We use pre rendered CFX.
Is there a way for me to output certain in and out points instead of a whole sequence. I have a long clip and only want a small section of it, where in Smoke 2013 can I input the in and out points I want rendered? I can't see it in CFX and If I mark an In and Out point on the timeline it still renders the whole clip.

Im on a mac with mavricks OS and i have done what it says and changed it but it go's back to the setting that it was on the one that does not work.
I have installed After Effects CS6 in a Mac running 10.6.8(Snow Leopard) with 4 GB ram and have installed all the updates of After Effects. Whenever I try to get the audio output, i get an error: " After Effects Warning: Unable to start audio playback. confirm your audio hardware is properly configured or change the driver selection in Preferences: Audio Hardware "
I tried to reinstall the software and also I tried the Audio MIDI Setup configuration but it too is of no use.
I am using a Lumix GH3 camera and recording in .mov at 50fps progressive and 50mbps. My computer is a macbook pro two years old with 2.2ghz intel core i7 and 8gb of ram (1333 MHz DDR3).
The footage plays fine in the editing suite until I add an effect then the playback is extremely slow and jerky even after render. I am new to PPCC and I've just moved from FCP 7 as it didn't recognise the footage at all.
I've been having an issue where the RAM cache disappears as soon as the RAM playback is stopped. Just to be clear, I'm referring to the green indicator along the top of the timeline so you know which frames are cached. This happens on various computers in our facility. It seems to be more common when multiprocessing is enabled. It also happens if you tell After Effects to RAM preview and then switch to another application. After Effects will complete rendering the RAM preview in the background, the icon will bounce in the dock to let you know it's ready, but nothing is cached when you switch back to After Effects. This is something that I've noticed for a couple of years over multiple versions of After Effects both at home and at the office. It seems to happen fairly consistently with specific comps which makes me wonder if it's related to any of the effects that have been applied in that comp.

I'm new to Premiere Pro CS6,I thought I had a pretty powerful computer all things considered. Basically, what's happening is the moment I put any sort of basic video effects on a clip, (e.g. "brightness & contrast" or "fast color corrector") the video playback (but not the audio) becomes extremely choppy and laggy. Playback and overall performance are excellent before I put effects on. It's just the moment I put some on it slows down tremendously.
View 2 Replies View RelatedI created a 3D object (a Doctor Who TARDIS) just for fun and I'm trying to figure out how to animate it spinning in space with the orbit camera and keyframes. I do the orbit and the keyframing works fine, but when I play it back the whole thing zooms in and out madly, almost like it is throbbing in and out. This funny "throbbing" happens in between the keyframes.
The zoom attribute in the camera options is actually locked, the only attributes changing as I move along the timeline are the position attributes, which I am keyframing off.
why I am getting a difference in my result between the preview screen in max and the actual output file. I have had to re-render hours because the finial result came in much darker then the preview screen and I had to crank up my lights. I think even the quality was better in the preview screen.
View 3 Replies View RelatedIs it possible to insert time from where the 'Current Time Indicator' is across all layers?
So it would extends all the layers and move all the keyframe accordingly..
In the adobe flash days pressing F5 would achieve the same effect.
So using this image as an example, pressing F5 would extends the layers/move all the keyframes after the indicator by one frame...
Why is it that AE skips some frames after playing back my comp?
View 2 Replies View RelatedI'm trying to fade some text from 100% opacity to 0% over 45 frames, and end my layer when it gets to 0, (Thus making it dissapear?). My text stays there with 0% opacity (Slightly visable), untill the next layer begins.. I don't understand why I can see it when the layer it's on has ended. I preview it with audio using num 0.
This has happened to me multiple times and I can't figure out what I'm doing wrong. Some of my text fades and dissapears normally, but I don't understand what's different about it. I'm probably doing lots wrong, but I'm pretty new and you have to start somewhere! This is also my first post, hope it's in the right forum.
why when i use the little window in the exposure control to render a preview so i can adjust the exposure. but does not matter what i do, it just stays black. i am not doing anything different than before so i am assuming a toggle switched on me and now nothing. it renders just fine, preview is just broken or disabled.

View 4 Replies View RelatedI'm working with a JPEG image sequence, and have deleted frames frames at various points before bringing them into AE. Instead of skipping the missing frames, AE renders missing media frames in place of the ones I deleted, instead of just skipping them. Is there a way around this without having to manually rename all of the images so there are no missing numbers?
