Media Encoder audio glitches in all rendered video files

Recently Media encoder starter adding glitches to all render video files in the audio track. It will sporadically cut in and out from a different audio track from different video file. Has anyone else had this recent problem?

If you're looking to edit Divx files, the others have offered good advice. If you're looking to create Divx files, I recommend using an external convertor rather than AME.

Adobe Media Encoder: Audio won't export with video

I am trying to convert an AVCHD video for viewing on my iPad 3. I use Adobe Media Encoder and select the iPad 2 settings (1920x1080) and it exports the video perfect, but no audio. I have "Export Audio" checked off. I tried it with 5 other settings and it just wont include the audio. Any ideas?

Seems random people are running in to this, so hopefully this solution will be found by whomever's looking.
If you're exporting video files from Final Cut Pro as .mov, and then trying to convert said .mov to an .mp4 using Adobe Media Encoder and are losing audio even though you're multiplexing, try this...
Make sure that you export only a 2-channel audio track from FCP. When I export from FCP, I split my audio into various tracks by default. Great for making master clips, but problematic if uploading to YouTube or doing further encoding in Adobe Media Encoder. Like YouTube, if you have more than 2 tracks of audio, Media Encoder seems to get confused and ignores all audio tracks. Combine all audio into a 2-channel stereo track and see if that solves the problem.
Regardless of editing program, see if reducing number of audio channels from source clip solves problem.

IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

iMovie 11 audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!

Thank you for the quick response. Unfortunately, that doesn't fix it.
I have the same issue when I try to export it through Adobe Media Encoder. I even tried to go through using After Effects and export through Adobe Media Encoder with the same results. I'm wondering if I might be better off uninstalling then reinstalling all my adobe programs.

Did the back and forth between PC and Mac file systems screw up my files somehow?
Yes. Unfortunately the move has almost certainly caused the loss of the resource data that would have been (invisibly) attached to those files.
By adding a specific .mov extension after the fact you will have helped the Mac correctly identify the file type / asscoiations but also significantly you will have physically changed the filename eg from "clip" to "clip.mov". This means that when you come to reconnect the media in FCP , then FCP will be looking for files that no longer exist at the given path eg when specifically looking for our example clip called "clip" of course it won't find it.
Try this as a test... first remove the ".mov" extension from one or more of the clips, select those clips and press Cmd-Opt-I to open an Info window for the selection. You'll see an "Open with:" popup and in that popup you should choose QuickTime Player (if its a Unix Executable then it will initially list Terminal as the appropriate app, you have to choose Other... then in the open dialog choose Enable > All Applications and then navigate to and select the Quicktime Player app as the appropriate app). After you've done that restart FCP and see if you can now reconnect to those clips.

Premiere CC and/or Media Encoder audio bad renders

Occasionally, but not always, when I export a timeline to Media Encoder queue, the video renders out with no audio.
I have not found a repeatable way to replicate this, but when it happens, it really blows up my workflow.
Typically I:
Import a ProRes 1080 clip into a fresh timeline, and only trim down the ends. Audio and Video playback great in premiere. I then, without changing anything, export to media encoder queue in h.264 1080p OR 720p (vimeo preset).
The queue runs and bang, video file with no audio.
My extended workflow is as such - once the h.264 file has arrived in the folder (it is a watchfolder), there are presets set to create OTHER Files - wav for CD, mp3 for podcast, DVD for distro, mp4 for podcast. So, as you can see, it snowballs into a trainwreck. I would also automate/schedule the podcast postings, but obviously I can't rely on media encoder/premiere to do it's job.
Has anyone experienced any lack of audio render issues? Is it tied to hardware at all, or is it just freak randomness? I even got to point to where I reboot the machine right before each original capture begins, but the error is always in the first render out of premiere.
I have checked for any muted tracks and such, and there are none. As I said, it is VERY random. For instance, this week, I dropped the capture into a timeline, exported as usual, and got a bad render. Did it again, this time moving the audio down a track. Still a bad render. Rebooted the Mac, tried it all again, and finally got a working render. This is the first time it has happened TWICE in a row, and I'm getting tired of it, as these renders are fairly long.
Any help would be much appreciated.

Ben, I'm having the same issue. Never had it before yesterday.
I'm editing on CC with R3D's. I have 8 tracks of audio. When I'm exporting (either through Encoder or through Premier) I'm getting a final product that has no audio, and in its place a loud clicking sound. I performed a number of reboots and got it to export once. But I've tried dozen's of times now and can't get audio to export through this sequence.
When I go to render the project I'm getting an "Error Compiling Movie. Unknown Error" message. I suspect that's related. Not sure what's happening. I'm going to keep testing. I'll let you know if I discover anything. But it is VERY FRUSTRATING:( Deadlines are looming.

Media Encoder CS6 Not Exporting all Audio Tracks From Premiere

I'm working with DSLR footage, 2 Channels of .WAV audio from an exernal recorder (H4N), and a 1 channel .WAV Music track. 3 Channels total of .Wav audio.
I can export from Premiere Pro CS6 to H.264 just fine, but if I try to send it to Media Encoder, it only track 3, which has the music.
I can't figure out this issue, and haven't found an answer on any forums. This problem effectively makes Media Encoder useless to me, so I would prefer it to be solved, rather than find a work around.
Thanks in advance for your help!

I'm having the same problem. But even worst.
For the test, I take a 10 min .mov or mp4 file, simply modify the "scale", and hit the export.
a 10 min file is taking 4 hours to render.
This is on a:
2012 MacBookPro i7 2.3Ghz, 16 GB 1600 DDR3, SSD disk. - Mac OSX 10.7.5
and a:
2011 iMac i7 3.7Ghz, 16 GB 1333 Mhz, 7200 RPM HD - Mac OSX 10.7.5
The CPU stays at 90% idle the whole time.
I know this is an old thread, but maybe someone could give me a hand.

Is Media Encoder capable of utilising all hardware resources?

I have recently built a new workstation for video editing and I am wondering about Adobe Media Encoders ability to use all resources. The system has:
Intel Xeon E5-2680 v3 2.5Ghz with 12 cores
128GB DDR 4 RAM
Nvidia Quadro K6000
Nvidia Tesla K40m
A network connection to a SAN capable of over 200 MBps (yes that is bytes)
Samsung SSD as the OS and application disk
I have the Quadro and Tesla setup with Nvidia Maximus, compute tasks are off loaded to the Tesla while the Quadro handles graphics. As you would expect the machine is exceptionally quick.
However when using Adobe Media Encoder it just doesn't seem to use all the resources available to it. When I am transcoding a tonne of files it uses a fraction of the resources available to it. This does mean I can keep editing and doing other things without any slow down, but in some instances I would prefer if it just ploughed through the files as fast as possible. Watching utilisation on CPU, RAM, GPU, and I/O; none of them max out. CPU never really goes above 20% total usage over all cores, it easily has 50% of the RAM free, the Nvidia control panel shows between 10% and 14% usage on just the Tesla and the network I/O is between 350 and 450 Mbps. I have seen all resources more heavily used when editing in PP, especially the network I/O to the storage.
Are some of the codecs more efficient than others or is AME just not that great at using the resources of such a powerful machine?

Sometimes a project can be weird/corrupted and do strange things. Then you need to outsmart the computer. For example, try an audio-only export. Create a .wav file and import back into project, and if all tracks are properly represented in that mix, add .wav to timeline, mute all other audio tracks, and do your final AV export using that new audio.

Media Encoder Audio Distortion

I have been trying to get my settings correct for the media encoder to not distort the audio on certain video samples. It seems to be slowing down the audio so it sounds very low on DiVX5.0 Video codecs but not others. I could not find a support forum for the Encoder, so I am posting here.
Can anyone help me with any references or resources for making the encoder not distort the audio samples when converting video files? I have tried multiple transcode settings and the distortion seems to be source dependent. Some files work, some do not.
Is there some sort of work around, like extracting the audio, then repasting it to the converted video? Or converting my DiVX5.0 files to a more compatible format? That's all I can think of right now, but I would much rather modify the settings within the Encoder to work correctly the first time through. Perhaps some sort of divx5.0 plugin? I will be looking for more solutions. In the meantime, any help would be greatly appreciated.
Sincerely,
James

When I add my composition to the Adobe Media Encoder from After Effects, it renders out incorrectly?

Why is it that when I add my composition directly from after effects to the adobe media encoder, it renders out of the adobe media encoder incorrectly? By that I mean the video comes out a little scrambled- parts of it overlap other parts. Is this an issue with 'dynamic link'? Did I do something wrong? I'm working in CC.

I also don't understand what you are saying. What do you mean by "parts of it overlap other parts"? A screen shot might help.
What were your render settings in AME? (Format, Codec, data rate, etc.)
What is in your AE comp? If footage, tell us what format, codec, etc. Tell us what effects were used too.
What exact version number of AE CC are you using?

Adobe Media Encoder ruins the quality of mi video

Hello, I have a motion graphics video made in After Effects, I've rendered PNGs and import them to AE again to add final touches and when I render ir with AME with the Android Tablet 720p preset and it always make a specific section look terrible pixelated. Why is this, I even tried encoding just the PNGs alone and still does it.
I tired this peset b/c I want my file not to be that heavy. The Youtube 720 HD preset works fine but my file is over 200 MB.
How could I make the Android tablet peset work or get a lower encoded file?
Thank you

NO!
An H.264 is a bad choice for an intermediate file. You don't want to introduce compression multiple times!
DIsrael20xx wrote:
I don't know how to choose a PNG codec. Is it a PNG secuence?
Choose QuickTime as your render format in the AE Render Queue. Then choose PNG as the codec. A decent alternative is the Photo-JPEG codec; it's a bit smaller in file size. While Photo-JPEG isn't technically lossless, it is visually lossless at high quality settings and is good for most intermediate uses.
Both of these options are technically image sequences in a QuickTime container. The big benefit of this over rendering an actual image sequence is that it behaves like a video file and you get audio and not just pictures.

Media Encoder (AMC) F4V - none of the video setting effect file size????

When I used to use sorenson squeeze, mov i could get a web flick down to 15 MB by reducing frame rate or size.
when using AMC - F4V - no matter what size or settings the same movie satays at about 34MB (with olny slight varistions if i tweek audio)
How do i get the file size smaller if none of the video setting effect file size????

In the limited amount of comparison testing I've done, I've found that 2-pass VBR files are consistently smaller than CBR files, all other things being equal. They're not always a great deal smaller, but they've never exceeded the size of the CBR files, and this goes for any type of encoding I've done, whether it's MPEG-2 for a DVD, or a web format like WMV, FLV (VP6), or H.264. This seems to be true even when the target and the maximum bitrate for the 2-pass VBR files match the bitrate "quantity" of the target bitrate of the 1-pass CBR files, and I've noticed this in any encoding application I use, whether it's AME, Sorenson Squeeze, or TMPGEnc Xpress. When analyzing my VBR-encoded files using an application such as MediaInfo, the average bitrate that is reported is never even close to my max bitrate, and is usually well under my target bitrate.
I see two reasons for this:
If you're encoding with CBR and set your bitrate at 1000kbps, for instance, the encoder will simply allocate 1000kbps of bandwidth (divided by the frame rate) to each and every frame of video, regardless of how complex or simple each frame is. Each frame will be compressed to as near 1000kbps (divided by the framerate) as possible. Using CBR, you can more or less estimate the end file size by multiplying the bitrate by the duration in seconds. Think of it as filling a series of water glasses: with CBR, you fill each glass full, regardless of how much each individual actually wants to drink.
If you're encoding with 2-pass VBR and set your maximum bitrate to 1000kbps and (for argument's sake) your target bitrate to 1000kbps as well, the encoder will use the first pass to figure out how much available bandwidth is needed at each individual point of time, and that writes that to a log file that the second pass of the encoder then uses to properly allocate those available bits to the frames that need them the most. If a particular passage of the video can be encoded at a lower bitrate, and still maintain a prescribed level of visual quality, the encoder will simply put the squeeze on a little more. Back to our water glass analogy from above, this is the equivalent of filling each water glass with only as much water as each individual wants.
For example, using the max/target bitrate set above, a low-motion/low-complexity passage of video may be able to be encoded at only 500kbps and yet maintain the visual quality of 1000kbps. This results in a fewer bytes needed to encode that particular duration of the video, and usually there are multiple sections in a video that can be treated as such. This has a cumulative effect and subsequently results in a final encoded video that has a smaller file size than it would had it be encoded at the same bitrate, but with CBR encoding.
I'm not a software engineer or mathemagician, so I can't back all this up with empirical evidence, but in real-world practice, these have been my observations. Long story short: I always use 2-pass VBR for web-distributed encodes, and enjoy both smaller and better-looking files, at the expense of a coffee break.

Media Encoder CS6 Not using all CPU Cores or RAM

I'm currently exporting a 90 second video (using the Vimeo HD 1080p preset), and it is taking about 30 minutes. This is extremely strange as I have an i7-990x OC'ed @4.5, 12GB RAM, SSD, etc.
I looked at Performance tab in Windows Task Manager, and saw 4 threads were not being used at all, only 20-25% of the CPU was in use, and only 6GB out of the 9GB I specified was being used.
Why isn't Media Encoder making full use of my CPU and RAM?

I'm having the same problem. But even worst.
For the test, I take a 10 min .mov or mp4 file, simply modify the "scale", and hit the export.
a 10 min file is taking 4 hours to render.

2012 MacBookPro i7 2.3Ghz, 16 GB 1600 DDR3, SSD disk. - Mac OSX 10.7.5
and a:
2011 iMac i7 3.7Ghz, 16 GB 1333 Mhz, 7200 RPM HD - Mac OSX 10.7.5
The CPU stays at 90% idle the whole time.
I know this is an old thread, but maybe someone could give me a hand.
