Adobe Media Encoder CS4 - Missing audio at the end of clips?

I'm running AME CS4 in conjunction with a Matrox H.264 accelerator card for MP4 encoding. Source material is .m2t and output is 720p as per YouTube spec.
I've been noticing recently that every other encoding job will chop a second or two of the audio from the end of the clip. ie. The audio will be fine until the last second or two of the clip, which is completely missing.
I'm lost when trying to figure out where to start troubleshooting. On a side note, I have noticed the same behaviour when transcoding .m2t files within Encore, which was part of the production bundle.
Any ideas? Thanks in advance!

I cannot guarantee that it is not a software issue. Sometimes Matrox is an easy "target." However, with several other Matrox users having similar issues, it does seem that Matrox might be the common element.
One of the issues with troubleshooting Matrox issues with PrPro is that few of the normal responders here have Matrox. Many tried the cards, and most unplugged them for various reasons. Some, like me, have never used them. That kind of limits the responses here, unless a Matrox-user, who has addressed such issues successfully, drops by with some tips.
Good luck, and please update the thread, especially if you do get a "fix." Others will benefit, and I will learn something new!

Adobe Media Encoder CS4 - missing formats

Hi
I wonder if anyone can help me with this. I have the Adobe Media Encoder as part of Web Premium CS4. In the Format menu there are only two formats showing FLV and F4V. I have seen additional formats on other computers and don't know why they are missing from my copy.
Anyone any ideas or tips on how to install them. I am running Windows Vista.
Thanks
GeorgeB

Hi Jerron
Thanks for getting back to me.
I suspected that may be the reason. I have downloaded the latest update but that didn't add any additional format.
No matter.
Thanks anyway..

Adobe Media Encoder CS4--Missing part of interface in Export Settings

Hi,
I have a Windows 7 operating system on a 32-bit dell computer. When I open Adobe Media Encoder
I click on the Add button. Then I go to Edit->Export Settings. I am missing some of the
options for instance: adding cue points, parameters, and filters. I think it has a problem with Windows 7, but I'm
not sure.
There should be more options.
I put in my installation disk, but it does not allow you to just reinstall this program.
Does anyone know why this is happening. It works on a computer running Windows XP.

Adobe Media Encoder CS4 doesnt allow me to set the bitrate?

I have a Video file that I need to encode to several f4v
files at different bit-rates, but it seems I cannot change the
bit-rate in Adobe Media Encoder CS4?
I used the previous version to encode, but I cannot encode to
f4v, only flv.
Is there something I am missing here?

Sorry, found it,
Didn't realise I could scroll down to find more options in
the Encoder Window

Adobe Media Encoder CS4 doesn't encode audio

I'm having trouble getting the Adobe Media Encoder CS4 to
work properly. I have tried multiple files of different lengths but
end up with the same output. Nice video encoding, but the audio
starts and then cuts out after a couple of seconds. The longer the
video, the shorter the audio works. The logs don't report any
issues. Anybody have any ideas?

I have the same problem just trying to crop an FLV. (Encoding from FLV to FLV on Snow Leopard).
The audio just dies about 5 seconds in (the clip is 28 seconds long).
Sucks. I wish I could find the original .mov
I wish I wasn't forced to recompress the audio.
I've tried various settings all night - most settings result in no audio whatsoever.
Also, Media Encoder alters the mod date of my original file. Why?
I'm really frustrated with this software.

No audio on Adobe Media Encoder CS4

I'm using Adobe Media Encoder CS4 (4.1.0.107) to convert an MPEG2 clip with WAV audio to FLV or to F4V.
The export audio checkbox is checked but the output file I get has no audio.
I'm using Windows Vista SP2.
Please I need your help !!!

I have VBR as an option under FLV/F4V. Multiple passes, too.
Nothing special here. I have used most of these settings to test them out (VBR multipass wasn't available previously in PPro) and compare them to my Sorenson Squeeze results. You'd be better off with Squeeze, but it's not too bad in this version...much better than the previous implementation of the On2 VP6 encoding.
Different vendors with their different applications utilize codecs differently. In other words, just because VBR or multi-pass encoding is part of the available spec on a certain codec (for example, On2 VP6) does not mean that the entire spectrum of options will be fully implemented in your application of choice. Sorenson Squeeze has one of the better utilizations of On2 VP6 available for the price.
EDIT - Make sure you are using Flash 8 and higher, not Flash 7 and higher. Sorenson Spark codec is limited to CBR. It's all available in the video tab under Basic Video Settings and Bitrate Settings.

F4v encoded with Adobe media encoder CS4 (longer than 71 minutes)

Hi I don't know if this is the correct place for this post. So apologies me if this is the wrong place.
Encoding with Adobe Media Encoder CS4 (4.2.0.006 and 4.0 too)
Source: MOV (DVPAL) longer than 71 minutes
Dest: F4V (H.264)
Result: freezed frames and only plays audio at 01:11. Media Player goes crazy and starts showing some diferent parts freeze frames.
In Quicktime crashes, in VLC the same of MediaPlayer. Sometimes the audio starts to downsampling and sounds like the pitch goes down.
Totally agree with this other post: http://forums.adobe.com/thread/580391
(extract)
I recentlly encoded afew F4V using Adobe Media Encoder Cs4. MOst of them are working properly but I don't know why, all of my video that are longer than 71 minutes seems to have trouble playing back. They all Freeze when they reach 71 minutes or if I navigate pass this point.
thanks and help us please!

Thanks for the interest.
I'll try to explain all details:
MacPro 1.1 (mid 2006) under Mac OS X 10.4.11 (Darwin 8.11.1 kernel)
System files: journaled HFS+ and a unix based NAS (under samba connection)
I have all material on the NAS and also I make the transcoding over it. Is a simple mov containing DV PAL WIDE interlaced 25fps with stereo audio. typical settings with nothing out of DV PAL standard.
The version of MediaEncoder CS4: 4.2.0.006 (it happens with older versions too)
The settings of MediaEncoder are:
Audio: AAC stereo 44,1 kHz
Video: F4V. MainConcept H.264, fps like source, profile high, level 4,1. CBR compression.
The problem only appears with videos longer than 71 minuts. At 01:11 starts with crazy problems. It seems like the player have some read or problems.
Tell me if you need some other kind of information.

Adobe Media Encoder CS4 Causing Jerky Playback with Speed Changes

Using Adobe Media Encoder CS4 for MTS files

Hey everyone, I did some searching on this topic to no avail so here I am.
Anyway, I recently got an HD camcorder that records in 1080i AVCHD.
I have no problems getting the MTS files off of my camera but as I'm sure you can imagine, working with those files is a whole other issue.
I've found that Adobe Media Encoder CS4 works great in encoding these files to QuickTime format (.mov) but the problem is that the resulting file size is actually bigger than the original MTS file which is unacceptable, especially considering I'm encoding the files from 1920x1080 down to 1280x720.
Does anyone have any experience using AME CS4 to convert MTS files to a more workable 720p format for uploading to YouTube?
I've tried a number of different custom settings to no avail (where you see an "or" is where I've tried different options):
Format: QuickTime
Video Codec: MPEG4-Video or H.264
Quality: 100
Width: 1280
Height: 720
Frame Rate: 29.97 or 23.976
Field Type: Lower First or Upper First or Progressive
Aspect: Square Pixels (1.0)
I won't list the audio options because I don't think that has any bearing on my problem.
Any ideas as to why the encoded file sizes are actually larger than the MTS file sizes? Maybe AME CS4 is not what I should be using for this task?
Thanks for your help,
Tom

I figured it out.
If you select H.264 as the format you can then select YouTube Widescreen HD for the preset.
This will set everything up to convert your MTS file to 720p and reduce the file size by around 30% with little quality degradation in my experience so far.
The only problem I encountered was the video was kind of choppy when the camera panned but that was remedied by upping the frame rate from 24 to 29.97.
Hope this helps someone and if anyone has any suggestions to improve efficiency or reduce file size post it in here.

Adobe Media Encoder CS4 Suddenly Adding Black Bars To L & R

I think I may be going crazy.
Every video I have ever shot has been cropped to 720x340 in After Effects then exported as an uncompressed Quicktime movie file at 720x340. For the last year I have done this process exactly the same everytime.
On my website (www.stevenbogda.com) videos are either 360x170 or 480x226 FLV files, both variations of the original 720x340 Quicktime file. I would just bring a 720x340 file into Adobe Media Encoder CS4, adjust the dimensions and bitrate and export and it would work perfectly. Now all of the sudden, when I bring anything I shot and exported recently into AME CS4 to get it ready to go on my website, it adds BLACK BARS to the left and right side of my video (refer to image 2).
I thought it was just a visual problem in AME CS4 until I exported it as the FLV file that I planned on doing, just to find that the actual FLV file is in fact the dimensions I wanted, EXCEPT it has black bars on the right and the left...
I immediately blamed it on After Effects and started re exporting uncompressed Quicktime files with different settings and managed to get AME to work properly but it was random. Some videos were exported with "settings 1" and worked in AME but other videos with the same settings didn't work.
I went to my hard drive where I store my master Quicktime files that were used to make the videos on my site and brought some into AME CS4 and they acted the same way that the new videos I made do, with black bars on the left and right. These videos worked the way I wanted them to in AME CS4 last month, but now suddenly are doing what my more recent files do and I have no idea why.
I found out that by lowering the width of the video (refer to image 3) the black bars would dissapear slowly, but then the video would be a smaller width that it should be. I really think I am just missing something, or set some setting wrong by accident because this never used to happen and now is happening with files that once worked correctly.
Any help or ideas would be greatly appreciated because I am spending way too much time re exporting uncompressed files just to find out they don't work.
Thank you,
Steven

Stan,
I was using the on2VP6 codec at data rates from 275k to 400k with good results. -- with the new CS$ endcoder i am used h.264 at 500k to 700k, video quality looks good but the graphic overlays look like alised crap. In the encoder settings the edges of the graphics get jaged when I make the field order progresive...
I am starting with DV NTSC video at 720x480.
I am going to go back to my old work flow and test it. The settings are a bit different from premiere pro 1.5 to CS4 -- in 1.5 i could export out an unconpressed .mov with square px and then bring that large file to flash media encoder to create the .flv

Adobe Media Encoder CS4 will not convert .mov video

Hello,
I have Adobe Media Encoder CS4 installed on my computer and I'm trying to convert a .mov video into a format that can be edited on windows movie maker and when I convert the video it converts the audio just fine, but there is only a black screen. Any ideas as to why this may be happening?
Thanks in advance.

No video tab in adobe media encoder cs4

Hi,
I'd like to change the bit-rate when I export, but I have no video tab in adobe media encoder cs4 v4.2
http://adwords.google.com/support/aw/bin/answer.py?hl=en&answer=105647 explains how to change bit-rates but it unfortunately doesn't help me.
Any ideas would be apprciated.
Michael

I found the video and audio tabs etc.
First open in, "device central".
And then if you have "basic settings" displayed you still can't see the "bitrate" and "advanced settings".
You either have to scroll down, or close "basic settings".
And then all is revealed.

Adobe Media Encoder CS4 runtime error

I am wondering why I am getting a runtime error while
attempting to use Adobe Media Encoder CS4...As soon as I launch
Adobe Media Encoder CS4, it crashes I have installed and
reinstalled Flash a couple time, to see if this corrects the
problem, which it doesn't, and just last week it was working
fine...Does anybody have a ideal what is going on?

Don't know if this helps anyone else, bt the runtime errors i have been getting occur when I try to build and burn a blu-ray file. And they happen intermittently. In fact, on this project, I had burned several test blu-rays without difficulty. When I made one minor change on the penultimate version, and tried to burn again, the system crashed with a run time error. Then it crashed 9 more times over the course of the week.
Finally in frustration, I created an interim ISO file in Encore- ie in the build workstream, i selected burn an image file rather than burning a blu-ray disk. After this intermediate step completed, i then did a separate burn in encore but burned from the image file. No snags.
Not sure why but this program has trouble doing a sequence of activities. As it is, I already render and save the file before burning. Now I have another interim step to create an image file before burning.
In my next hardware change, I am going to switch to make Mac and Apple software. Enough of MS Windows and Adobe, the GM and Chrysler of the software industry. Hopefully what my friends tell me is true; that Apple stuff actually works.

Adobe Media Encoder CS4 Encoding Error

I got an error when Adobe Media Encoder CS4 encoding which is the crash of ImporterProcessServer. It crashes the halfway of the encoding process. I restarted my comp and tried several times before but the results still the same. Sometimes ImporterProcessServer did not crash but the encoder failed compiling without any error.
Processor : Intel Core 2 Duo E4600 2.4GHZ
RAM: 2GB
OS: Win7 32bit
Graphic: Nvidia 8600 GeForce 512 mb

First thing to check is what is on the Timeline at about the 50% point. Do you have an odd Asset there?
Do you have a gap in the Video at about that point?
Then, do you have adequate defragmented free space on the destination HDD?
Good luck,
Hunt
