Export flash vid with VBR? (variable bit rate)

Does AE CS3 have a choice of VBR when exporting Flash Video (FLV)? I'm going thru the Render Queue, but can't find where to change it from CBR.
Thanks, Mates!

No, I don't think so. After Effects only does one-pass rendering/compression, so you're probably better off with Flash Video Encoder or something similar.

VBR Variable Bit Rate MP3s...HELP!!

I posted a message yesterday regarding pausing problems with VBR MP3s. It seems 2.1.1c playing MP3s using the performance pack has problem pausing and resuming MP3s if they are VBR. I decided to switch back to 2.1.1a and low and behold, now if I play a VBR MP3 it halts at some random point in the middle of the MP3. When I say random I mean it is different for different MP3s but that each track will always halt at the same point. There are no exception thrown but it looks to me like some kind of buffer overflow. Please anybody out there, can you help??

MP3 support was removed from 2.1.1c due to license changes. According to Sun, JMF should now use whatever system decoder it can find. Perhaps upgrading DirectX would help.

"Variable Bit Rate Audio Not Supported"

Hello -
I have several AC-3 files - sourced from satellite broadcast downloads - surround 5.1, 448kbps/48kHz - that I cannot add to DVD SP. When I attempt to import them into the assests pane, DVD SP reports they are incompatible giving the error message in the subject.
Any ideas?

I too have noticed this today when trying to import a new CD. Every track has a variable bit rate despite not requesting it.
The older version of iTunes did not do this, just this new 7.5. I cannot seem to resolve. I tried to create a custom import without VBR but it ignored this too and did it anyway.
Apple, please help! This must be fixable somehow!

Variable bit rate on importing bug in iTunes 7.5

I have tried importing a new CD into iTunes 7.5, installed this week as an update to the previous version.
Now each track imported comes in at variable bit rates. I cannot seem to stop this. I tried to create a custom import rate without VBR but it ignored it anyway.
Is there a fix for this? 7.4.x and earlier versions was fine.
Mark

Apparently it is related to the new QuickTime AAC encoder.

PROBLEM with 24/96 bit-rate USB DAC that worked fine until I plugged in two

I'm using a late 2008 15" Macbook Pro that I bought Jan 2009 right before the SD card models came out. Mac OSX 10.6.4 and iTunes 9.2 are installed. I have a Nuforce Icon HDP and a CEntrance DACport 24/96 bit-rate USB DAC (external sound cards) that still work great right now. Note - 16 bit/44 Khz is CD quality, and these 24/96 files are hi-resolution downloads that are closer to SACD or DVD audio.
I have been evaluating a new third 24/96 USB DAC plugged directly into the Macbook USB port (no hub) which has been working fine for over 2 weeks with 24/96 bit-rate lossless music files in iTunes. Audio Midi Setup is set for 24/96 to match the music file's resolution. After making suggestions to the manufacturer they made some improvements and sent me a new version to listen for the differences.
I listened to the new one for a day and it worked fine, but when I plugged in the original test sample into the second USB port at the same time as the new one in order to compare them, the sound became garbled and noisy. This never happened when either one was plugged in by itself. Note, if I make changes to the DAC's bit-rate in Audio Midi Setup I usually close iTunes first and then re-open it when I am done.
Upon hearing this new problem I unplugged both of the new USB DACs and plugged just one of them back in, but now it causes iTunes music playback to pause when one is plugged in and set for 24/96 in audio midi setup. Prior to plugging in both at the same time, either one worked just fine by itself. There is no reason when unplugging one or the other that they shouldn't start working again. But now I can't play any 24/96 music through either one anymore. In quicktime player the songs don't pause like with iTunes, but there is no sound coming through even with just one DAC plugged in at a time. Then I discovered that if I go into Audio Midi Setup application and lower the bit rate to 24/48 then iTunes will resume playing again and I can hear the music fine with iTunes or Quicktime player.
Basically, my Macbook Pro has now lost the ability to play 24/96 bit rate with either of these new USB DACs, when they both worked fine before I plugged them in at the same time. More confusing is that they use the same USB receiver chip as in one of the DACs that I mentioned above in the first paragraph, and both the HDP and DACport still work fine at 24/96 bit-rate. It's only these two new USB DAC that require me to lower the bit rate in Audio Midi Setup to 24/48 in order to listen through them, and this wasn't a problem as recently as yesterday!
The computer is acting like some setting needs to be wiped out - it's DEFINITELY NOT the USB DAC's that are faulty because they still both work fine at 24/96 on my wife's iMac (I'm afraid to try plugging in both at the same time to the iMac in case I screw that Mac up too).
I have reset the PRAM a few times, and this doesn't fix the problem. I thought maybe the com.apple.audiomidisetup.plist file could be corrupted and deleted it, but that didn't help. I don't know what to try next to get the Macbook to start fresh when trying to use these devices, short of having to re-install OSX.
Please, does anyone have a suggestion of how I can make the Macbook forget it ever saw these two USB DACs, and let me start fresh so they start working normally again? I do dozens of reviews for Head-fi.org and I can't afford to have my Macbook Pro compromised like this, which could prevent me from doing some reviews or evaluating new products.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!

Variable bit rate audio assets cannot be imported

Extracted some ac3 files from personal content DVDs I authored and burned myself (using DVDSP) to make a compilation. When I try to import these 5.1 ac3 assets, DVDSP is refusing stating: "Variable bit rate audio assets cannot be imported." These ac3 files play fine in QuickTime and other programs that handle ac3 files.
Can anyone help?

Hi:
Please give us some info about the original movie/audio formats and what encoding presets you used in Compressor.

How to export a flash project with a changing frame rate to a video

I have a Flash project that is a series of roughly 1000 images. The result of the images is a simple animation, and there is music imported on a separate layer.
There are moments in the music that I wanted to line up with certain frame changes, and there are sections of the music that I wanted to match up with a faster (double-time) frame rate.
I used this code in several places in the a code layer:
stage.frameRate = x;
The result is exactly what I want in SWF -- the animation speeds up and slows down at the exact right moments to match up with the music track, but it seems like it's just not possible to export this variable frame rate project to a video file?
According to the accepted answer on this post: http://forums.adobe.com/message/4019538, it seems that:
The export function in Flash Pro doesn't transcribe *frames*, rather it plays the Flash animation and records it like a camcorder
If that's true, then I would think there is a way to record a variable frame rate project into a video -- does anybody know if this is possible?

That or Premiere would both get the job done. After Effects might be more desirable as it has a feature called Time Remapping (right-click on the video layer, Time->Enable Time Remapping). You can add keyframes to any point in a video and then drag them around to speed up or slow down the video. That'll allow for very precise tweaks.
Finally all I'd suggest is when you jump into your next project, make a quick dummy test project to see if the software you're using is easily capable of producing what you want. It'll solve the headache of completing the project only to land where you are now. Now you know Flash won't play nicely with scripts and Export Movie. If your desired end result was always a video I'd probably use video editing software to make the video. There's some free stuff out there if you really look, but no, it won't be as nice as After Effects or Premiere by any stretch. Although when you see how amazing After Effects is, you'll probably want to buy it .

Variable bit rate is good

hello everyone,
I've been compressing dvd using compressor at 7.8CBR for my pass projects & it looks great. However on my current project I can't pull a good compression due to the large LCD screen in the background so I have to try vairalbe bit rate with min 6.5 & max 8.0 two passes & it looks great.
Does anyone has any similar experience?
I heard that compressor's VBR is not good so I 've never tried but to my understanding, it's better to do 2passes since the software would analyze the movie better.
just some note.
JP
ps: can't wait to upgrade to fcp studio2

It's said the Compressor 2.3 has solved all problems related with VBR in past versions.

PlayCenter3: variable bit rate: need to know numerical equival

I am using PlayCenter 3 on my desktop computer and always rip MP3s using VBR (the setting: highest quality). In short, I need to know the information that that setting represents; specifically, the guaranteed minimum bit rate. On my notebook I must use other MP3 software because I do not own a Soundblaster for the notebook. Since I am giving my desktop to my parents I need to know the numerical equivalent of the highest quality VBR setting so that I may enter that into the options of whatever ripping software I finally decide to use.
I learned about *guaranteed minimum bit rate* through reading iTunes' options box.
THANKS! :-)

Is the problem inherently answered in your question?
Why use VBR when you bounce? It's a compromise solution, and has it's own problems. What are soundclicks tech specs? Work to those, getting the file as big as you can, it takes moments to bounce multiple files of varying bit depth etc to see how far you can stretch things before you're over-budget on the file size.

Export Flash Video With Transparent Background

Is it possible to export an After Effects Comp to a Flash Video with a transparent background?
I have made a simple animation with no background. I'd like to export the Flash Video to go on a web site. I'd like to keep the background transparent.
Can this be done, and is there a checklist of what I need to select in "Make Movie"?
Thanks!

from "Render and export a composition as an FLV or F4V file":
"To include the alpha channel in the FLV output, use the On2 VP6 codec and select Encode Alpha Channel in the Video tab of the export settings dialog box."

Using Variable Bit Rate Encoding (VBR) and playback issues

I have been using VBR when making mp3 for download to "Soundclick.com" in the past, resently, I started to hear complaints from listeners, that my mp3 were garbled, although it is not consistent so, it is true, and I came to believe it was because of VBR. I re-encoded the files in question, and so far the problem has gone away.
The question is this due to OSX 10.5.6, or might it be something with soundclick, I don't know; but it did seem to become evident after loading the OSX 10.5.6 update. I can't find a way to correspond with Apple Development, so I thought to post here. I am also going to pursue this with "Soundclick.com"; VBR seems to be an efficient way to encode, and I would like to keep using it.
If anyone know about this it would be cool to hear for you!
God Bless,

PE 4 crashes on render, export and preview with Vista 64 bit

I just installed my PE 4 on a new Windows Vista 64 bit machine with the i7 920 processor and 512 MB ATI Radeon video card. PE 4 worked fine on my XP machine but I cannot get it to render, export or even let me preview on this new maching. I have followed the advise of updating all drivers and software and uninstall and reinstalling with nothing running and I get the same error repeatedly - it will render and progress for about 5 seconds and then I get "Adobe Premiere Elements.exe has stopped working" and it closes. The video clips are from a flash memory camera and the Presets set for widescreen - flash memory. Everything works normally until I try to view or render the files. Any suggestions?

You say this is from a flash memory camcorder? Can you be more specific?
Webbie camcorders, like the Flip, may shoot in hi-def, but they also record to a non-standard codec that can cause some of the problems you're describing.

What, exactly, is variable bit rate?

I understand the basic concept of VBR, but how does it actually work? I realize that more bits are devoted to the parts of the movie that have the most action. This means that other parts of the movie are subsampled in some way. Is it spatial subsampling, temporal subsampling, or a combination? Temporal subsampling could be done, for example, by dropping every other frame (although I doubt that this approach would give good results). Spatial subsampling could be done by rendering certain frames with less precision (similar to selecting a lower quality for a jpeg image). I have tried to figure out how this works by looking closely at samples, but I can't tell.

Michael,

I can not install Flash Player with W7 64 bit and IE9

I recently had a virus on my PC. Passing the Avast antivirus has had to delete some registry and since FP is not working in IE9. If it workd with Chrome.
The OS is W7 64 bits. I uninstalled IE9 several times and I have reinstalled. I have also uninstalled and reinstalled over 30 times FP and still not working, but no errors are detected in the discherge and installation.
The problem is that in the IE 9 configuration tool "Currently loaded add-ons" in "Shockwane Flash Object" appear Light Grey both options "enabled" and "disabled"
Thanks you very much for your help

Thanks Mike,
I followed your instructions and I created a new administrator account in Windows7.
From this new administrator account properly installed Flash Player and it works.
As for the old administrator account does not work, I have to check that may be happening in Windows 7.
Thank you very much for helping me to find the problem.
Best regards,

'Matched' Songes downloading with same (lower) bit rate.

Well this problem must been mentioned before but it seems hard to find in these forums - for me at least. I have found a few cases where people have confused 'uploaded' for 'matched' - but this is certainly not the case here. Though Itunes may be confusing the terms by the looks of it
Quite simply: several lower bitrate songs are shown in my library with 'Matched' as their icloud status. However when I delete them and download them from icloud, they come back with exactly the same bitrate as if they has been simply 'uploaded'. This happens to me on two different libraries on a Mac and a PC respectively (same account though)!
Is this simply a known bug - a work in progress?
Perhaps there is already a thread about this in which case could someone point me to it?

i have also noticed this recently. let me explain a bit of the background
had a mac mini which i bought itunes match on and replaced some (not all) of my mpeg files with matched AAC files.
i then bought a macbook air but because of the small size of the SSD did not download the matched AAC files to it. at this point i pretty much stopped using my mini to manage my music and just used to MBA to add / stream files.
due to some amendments i wanted to make to some of the track info on an album i downloaded it. even though it was fully matched i was surprised to see some of the songs downloading as matched mpeg's. i was pretty certain they used to all be AAC files.
sure enough i went back to my mini and noticed that the album had originally downloaded all tracks as matched AAC files. i have checked the file thoroughly to ensure it isn't corrupt or anything and it plays perfectly. as a test i then deleted the AAC file and redownloaded to see what came up, it downloaded as an mpeg!
my questions to apple would be
why are these files now reverting back to mpeg's after being matched originally?
and (perhaps more importantly) HOW did they get this file to upload? is it even MY mpeg or someone else's that uploaded? as i have stated originally it matched so no uploading would ever have taken place.
this isn't a one off i might add. i thoroughly checked my entire library of 10,000 songs and have over 300 instances of this happening where i originally had the matched AAC file and am now left with an mpeg.
more strange itunes match behaviour. coupled with the constant 11111 error, the long 'sending information to apple' time and the clean / explicit debacle equals very shoddy service so far. and no word from apple on fixes or even an aknowledgement this is happening. poor.
