After Effects :: Unable To Start Audio Playback?
Mar 6, 2013
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've uploaded MPEGs from Panasonic DMC-TZ7 on HD quality. Audio works fine when playing clips and when played on Quicktime. When playing back on Project, I get a chopped pulsing noise on some parts (although they play OK as clips). I used simple fade to black transitions and trimmed clips. When I finish project, the sound was OK on the first clip but I get no sound or the odd pulse of sound on subsequent clips.
I have re-installed VS pro X3 and downloaded the latest patches but it makes no difference.

I recently transferred collection of Super8 movies from a VHS tape and burned to a DVD. Upon playback on the computer, as well as preview prior to burning, the audio on the clips worked fine. However when the disc was played on the DVD player ( tried my blu-ray player as well), there was only audio in sections where I had added an audio track. Did I miss something ?

I am not new to this software and have made many videos. The problem is that I got a new computer with Windows 8 and installed X4 VideoStudio. I can hear the sound file when I select the clip but as soon as I select Project, there is no sound. I am currently uninstalling the program and trying to reinstall.

Using pro x4, when he imports a AVCHD clip and plays it back, the audio is distorted. The same clips audio is fine playing directly from the desktop, using windows media player. It also plays back fine in another video editing program.
(O.S Windows 7 Ultimate 64bit).

When I play the video "clip" mode, it is perfect. When I play the "project" mode, the sound cuts in and out. But not on all clips, just the .mov files. The .wav are fine. I just updated all the patches, (to my knowledge) and tried to make a new project.
I just figured out the the corel does not like .mov files. I converted to .wmw and it works.

Using Premiere cs6.Audio keeps dropping out during playback. Audio is present in the export.The audio drops out at random and drops back in at random.
I have tried everything from converting my wav to an mp3/aiff, moving my cache and preview files (and changing my scratch locations) to my computer from my external hard drive, creating a new project, deleting the pek files, even closing all apps.
This is something that just started happening out of nowhere in the middle of a project and has gotten worse and worse with use.

Have reinstalled Premiere Pro 6.0.5 because I cannot drag Audio Transitions or Effects to any Timeline sequences in my Projects. Have tried modifier keys, but to no avail.

I have used VideoStudio 11 happily for some time now but when I recently captured a HDV video in the DV format I found that the audio in some of the sequences plays back normally BUT some does not play back at all or only at a very very low level. The audio on the original tape is fine and I can see the audio waveform on the sequences that don't play back.

I just finished editing MP4 videos with Corel VideoStudio x3. I exported the videos in the same format. The problem i am having with all of the videos is that when I try to view them with Adobe Flash Player All I get is the audio portion of the video and the Adobe controller is visible. I have tried to exporting the videos in a few different MP4 formats but none seem to work?

I am editing in the timeline in Smoke 2013. I bring in a music track onto track 4. I bring in a interview clip on track 1. Only one or the other will playback and not together at the same time. I also notice on the audio tracks patch area a small square that when you place the cursor over and drag left or right I assume channels are being selected. What is this square box for and how do I get all my audio tracks to playback together?
I am using Panasonic P2 footage at 1920 x 1080. 29.97 NDF. I have brought them in through the media hub and created folders that correspond to each P2 card I stored on my Video Array. I am using a ProAvio Video Box with a RocketRAID 644 controller. What gives? Why am I not able to hear all the audio tracks during playback?

I have encountered this problem on all recent Premiere projects I've worked on with a variety of audio types. My audio is cutting in and out in a seemlingly random way while the video keeps running fine. Sometimes the audio will play fine for 15 seconds then stop, sometimes it stops and starts after about 2 seconds. I have tried adjusting all of my preferences, settings, audio types, and even video types but the problem always comes back. Spoke to a friend who's new to Premiere and he's having the same problem. Considering moving back to FCP despite the weak interface.
Currently I am editing Canon 5d Mkii footage at 1080p, 29.97 fps. I am using none of the audio attached to the video clips - only editing to a separate m4a music track. My audio is at 44100 Hz. I am playing back video at 1/4 quality. I am running a fully updated Mac Powerbook with a 2.6GHz Intel Core i5 and 8gb of RAM.

I've listed my setup below and then have stated the issue I'm experiencing.
27-inch, Mid 2011 iMac
3.4 GHz Intel Core i7
16GB 1333 MHz DDR3
AMD Radeon HD 6970 1024MB
Running Mac OS X Lion 10.7.5 (11G63)
Currently working off of a portable 1TB G-Technology G-DRIVE via FW800.
Working in Premiere Pro CS6 Version 6.0.2
Editing in a sequence with settings:
1920 x 1080 23.976fps (also tried in a 29.97fps timeline with same issue)
Working with footage that is 23.98fps
Working with a combination of ProRes 422 (LT) and native H.264 Quicktime files strait from a 5D Mark 3.
The issue I'm having is during playback the audio will competely drop out. The video will continue playing on just fine but the audio drops completely out. All audio levels drop as well in the audio mixer meters so it truly is losing all communication with my audio layers in the timeline.
I read in other forums to go into Finder and delete out the .caf files, re open Premiere Pro, wait for them to be recreated then carry on. I tried this approach with no luck. Deleting the .caf did not change anything. Audio is still dropping out as I try to play through my timeline. The only way to get the audio back is to pause then press play again. I have 5 total channels of audio with only 2 of those channel active.
This is incredibly frustrating have to export out a video just to be able to watch it through.

Every minute or so, I loose audio on playback (timeline or sources). The only thing that seems to fix the issue is cycling between AES BNC (or XLR) to Embedded and back, and the audio will playback fine again . . . for a few minutes, and then I need to recycle it again. I've restarted Smoke, restarted the computer, and down a full shut down and restarted . . . and the issue continues.

While editing a large video file (one hour), the audio playback worked for a while, but then simply stopped working. Can still see video and edit it, but without hearing the words / background, editing will not be correct. Is there a bug in the software or some way of reseting the file? I have noticed a similar issue with videos in LR4.

I have created keyframes from audio file and used them to generate some effect, all works fine, it is amazing how easy it is However, I would like to generate flash (?) so that these effects would be dynamic to different audio files after export.
What I want is basically to create effects that can be used in life event to the streaming music.

"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 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.

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.

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.

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?
Specs:
AE CC 12.0.0.404
Retina Macbook Pro / OSX 10.8.5
2.6Ghz Core i7
16GB RAM
512 GB primary SSD (where footage & cache is located)
3TB 7200rpm cache drive

I am currently trying out Corel VideoStudio Pro X4,when i insert different clips into the timeline, as the project plays the audio doesn't start instantly, and there's almost like a 1sec delay before the audio appears.
I seen that there was audio fade in/out options, which can be set to 1-999 (but no 0)

I 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.

I don't know why Corel made this program without the ability to change the playback speed in project view. You can only change the speed on each clip. When you have 50 or more clips, this can take all day, when it could take a few seconds if you can do it in project mode.
