Audio Render Prob

thanks for stopping by this post.. i have a pretty big audio problem happpening in FCP... i have a g5 ppc 2.5 ram with FCP 5.1.4, and i also have a 13'' macbook with intel 2.0 ram and FCP 5.1.4..... the problem is.. when i capture a whole 1 hr tape onto the comp wheter its on the desktop or the laptop.. the audio rate for the same file changes when when i open the same project on the the desktop computer...
so i create a project named "audio test" and capture tape #1...in the desktop the audio rate says 47.9999 k and that means i have to render a full hr of audio... in the laptop i open the SAME PROJECT.. with the SAME TAPE #1.. and i get the original audio rate of 48 k without having to render any audioo...
so whuts happeninig? any clues? much appreciated...
Mac OS X (10.4.6)

when you say same project, do you mean you have physically copied the project file from one to the other, or rather, you have simply created an identical project on each ... if its the latter then it may be an issue with the "identical" bit not being quite right.
alternatively it might potentially be a preferences issue, with the real-time audio setting having become corrupted on one of the mac's ... try trashing your preferences on the problem machine (FCP Rescue is a good bet for that)

Video Drive:Audio Render Files is missing

My Final Cut Express was working. Then I took a break and when I went to use it again I had to register the program. Once I figured where the serial number was I get this message...
"video drive:audio render files is missing. I don't know how to rectify this issue.
Any suggestions?

Hi David,
figured out the issue. the drive wasn't connected. Once I double checked it. the program fired right up. thanks for your help

Audio Render

Am I to understand that it is safe to delete audio render and render files? This will not cause a problem when I go to re-open the project? Just want to be sure.
Thanks.

Assuming all your original media is still in place, the only "problem" you'll experience is the need to re-create the render files as part of further work on the project.

Nested = audio render

I have a bunch of short sequences that I lined up into a stack reel for output to tape. So I ended up with one sequence that is comprised of a bunch of short nested sequences.
When I went to ETT, I got a window telling me that it would take 16 hours to render my audio. (This for a 25 minute sequence.)
Needless to say, I canceled the output. I tried various audio presets (mix to 2 channels, split to 4 channels) with the same huge audio render times when trying to go to tape.
I worked around this by un-nesting everything (cmd-dragging the sequences into the stack reel). The ETT worked like it always does with no audio render.
My question: what was causing the huge audio render times, and how can I avoid this in the future?
All sequence were Uncompressed 8 bit and no sequence had more than 4 channels of audio.

how can I avoid this in the future? seems like you already discovered a suitable workflow, ie sequence content rather than nests.
alternatively, it seems to me that the nesting is causing the Real-time audio mixing buffer to overflow, so you might try increasing that number in your FCP > User Preferences, and see if that helps
i'm guessing it is calculated such that each track in the master edit is a sum of all the tracks in the nest, do if you are doing a 4 channel output in both master and nests then that is equivalent to 16 tracks of audio
hope that helps
cheers

Unbelievably slow audio render times!

I've been dealing with his for a while now on this documentary I've been working on. When I export my timeline which is right around an hour, it takes around 2 HOURS just to render audio previews before it will export! The bulk of my timeline is a single track with no effects at all. Video renders faster than the audio! The only thing unusual about my project is it is largely composed of longish multi-cam sequences - about 30 sequences ranging from 30 mins to 90 mins. It's appears PP is rendering audio for every bit of my source sequences even though only a few seconds or minutes of each one is actually being used. I don't know what else could be happening.
I was thinking that since some of the audio was recorded at 44.1K maybe that was a problem and some of the sequences had several tracks of audio so to solve this I went through every sequence and rendered out a stereo mix at 48/16 and deleted the old audio. That seemed to help for a while as with CS6 I was getting a very annoying "rendering required audio files" message every time I hit play until I rendered the audio which as I said takes a really long time. Also I can render this but if I close Premiere and re-open I have to render it all over again. It is not keeping the audio render files. Premiere CC is better about playing back without the render message but it still needs to render for export. I have no idea why it would need to render audio from 48/16 source files.
I have reported this to Adobe but just thought I'd put this here to see if anybody else is having issues. If any audio rendering should ever be required in this day and age it should be extremely fast. This problem has really brought exporting to a crawl for this project.
Adobe CC, OSX 10.8.4 on a 12 core Mac Pro with a GTX 570 32GB ram, and BM Studio. My RAID is a 3 disk internal raid with 3 3TB disks in RAID 0. The video renders reload properly. The situation would be better if the audio renders reloaded at least but why it needs to render "audio previews" for such simple audio is beyond me. And as I mentioned I went through quite a bit of trouble to make it as easy on Premiere as possible by replacing all of the 44.1 audio with 48/16 wavs.

Let me start by saying I am only a hobbyist and do this more for my son and niece since they are musicians and play live in a number of venues. I am not an electrical or audio engineer (I am an aeronautical engineer) so what I am about to say is based only on what seems logical to me… First rendering audio should simply be faster than rendering video given the amount of digital data that needs to be processed. That stated, I know that the Mercury engine using CUDA to process video vastly speeds the rendering of video. Regardless, using today’s CPUs (i7 3930K in my case) should and does more than make up for the additional processing power for rendering video using CUDA.
It seems to me that there is a bigger problem than whether or not we are flattening, nesting or locking our tracks. It shouldn’t take as long as it is taking for some of us to render audio!!!
I only experienced this problem one time. I am not even sure what I did to change the outcome on the same project that I have since edited and rendered many times. But now the audio renders very quickly (less than a minute). I will say that in almost all cases my music videos have different audio sources (44.1KHz, 48KHz 16bit, 48KHz 24bit, and 96KHz 24bit) and that I set all my sequences to 96KHz since my master audio sources are recorded at that. I use an external firewire RME Fireface 800 using RME ASIO divers to handle all audio. I do find that this setup can be stubborn in that there are times PPro CC doesn’t know what to do regarding my audio so simply won’t allow me to play any track. When this happens I simply remind PPro CC of my settings by going to Edit/Preferences/Audio Hardware then check that the Adobe Desktop Audio is set to ASIO FireFace and click on ASIO Settings to check that the buffer size and sample rate are correct. If they are not I read the flash from the RME and all is good.
But I diverge, there is a problem Adobe and it needs to be fixed. This never happened to me using CS6…

30 Second Audio Render problem in Adobe Media Encoder?

I've been trying a few things out to fix this, but no luck.
Ok, so I export videos with a audio spectrums where audio would be necessary. Now I want to do this all in After Effects without editing the Audio in in Premiere Pro. After Effects does not render in H.264. So I send it Adobe Media Encoder. When I export to AME, the first 30 seconds is mute, without fail. only on AME though. I can export straight through AE with .mov and it works fine. but I don't like doing that with the large filesize. I also did this with WebM. Audio does not export for 30 seconds on AME.
I like to send everything to AME. So if I have to go to premiere to fix audio I will. so after fixing everything I send it over to AME and let it export. for some reason, it WILL give me audio. Is there something wrong with my settings in AE or AME?
Everything is CC if that helps any

OK, give this a shot.

Audio Render Problems Again

I'm having problem again rendering a one hour presentation. If I use Command/R, the dialog box indicates seven or more days. If I highlight the selection I get essentially the same estimated time.
Command/R usually works, but not this time. Audio For Playback is checked.
The DV timeline plays in Quick Time OK.
I desperately need to get this video sent out! I even deleted preferences using the "Preference Manager" program.
David

All of my lecture video series are recorded in LP 16 bit audio. Each lecture is between 1 to 1.5 hr in length. I have successfully completed 10 of the 23.
Each lecture is sent to iMovie HD and then the timeline.mov is placed into FCE. One other time the timeline audio would not render, so I converted it to DV via MPEG Stream Clip and placed it back into FCE. The lecture I'm having trouble with is #11.
As mentioned, usually Command-R will do the trick in 10 minutes or so, not 6 to 10 days.

A very unique Video & Audio Link Prob

Hi, i've been thru a lot of the Q&A to try to resolve my prob but gave up. This might be a 'newbee'.
One , lone clip on my timeline won't link. I've tried to link the vid & audio via the 'Shift+L" shortcut key and nudda. I've also tried via the edit/modify menu but the link options are not available (greyed out).
I've noticed that the Vid track is not underlined where as both audio tracks are?. This may be a big clue to solving the mystery?
Weird & frustrating!!!

Shift+L is for toggeling Linked Selection (the button left for the snapping button in the top right corner of the timeline window)
Keep that Linked Selection button toggeled (green). Then make sure your clips are linked. If you still have problems, it might help to trash your FCP Preferences. That can be done manually (/Users/Library/Preferences/Final Cut Pro User Data/), or you could use an application like FCP Attic or FCP Rescue. Remember to quit FCP before you trash the preferences.

Premier CC Audio Render (and/or export) causing crash.

Hello, I'm pulling my hair out with a rather large project.
Rendering Audio, exporting audio or exporting audio in Media Encoder ALL crashes my project.
The sequence has one aiff of voice on top of one aiff of music with no filters other than normalise gain to 0.
I've unistalled Soundflower, emptied my cache and deleted old render files.
Please give me some suggestions as I definitely can't rebuild this project in CS6 or FCP.
Thanks, Ian.

We can not see your computer, your settings or even know what your source files are because we are not in the same room as you are!
We cant see what you are doing wrong ...so you will have to tell us a lot more and show us some screen grabs of your settings.

Audio won't play after audio render

I have an MP3 on audio track 1 in Premiere/CS4, placed underneath video clips which I've unlinked from the audio and deleted/cleared those unlinked audio files. The MP3 file plays fine until I render the timeline and then it stops playing. If I 'double click' the file (placing it back in the source window) it plays fine there, but won't play in the timeline. I've included the file properties below. Does anyone have any idea why this is happening and what I can do to fix the problem?
Type: MP3 Audio
File Size: 4.2 MB
Source Audio Format: 44100 Hz - compressed - Stereo
Project Audio Format: 44100 Hz - 32 bit floating point - Stereo
Total Duration: 00:03:03:32868
Average Data Rate: 23 KB / second

I could do a MP3 to WAV conversion, but that defeats the
purpose of storing my (growing) music library in MP3 for space conservation.
I understand the space problem. Only do this for files that you are using as Assets, Imported into PrPro, if they give you a problem.
Seems I'm finding I have to do a lot of 'work arounds' with CS4.
Well, it does seem that you are not alone on this one. However, my problem came with PrPro 2.0. In my case, it only happened once, but did affect about a dozen Audio files in several Sequences. Did not realize the magnitude of my issue, and only observed it after a busy day of trying to Keyframe some Effects and doing multiple Renders to check things out. One moment all Audio in that section was playing well - next moment (after one more Render) dead. Others, who replied to my thread indicated that it had happened to them too, in similar circumstances. Trouble was, none of us could duplicate it and some had this happen on their first Render, while I'd probably done a dozen that morning. Have never had it happen again, and finished that Project with hundreds more Renders, just like I'd done, with not one problem. I certainly can not call it a Bug, as there was no way for anyone to reproduce it. Still, whatever allows it to happen, under the right (or wrong) circumstances seems to be around two generations later. Hey, phases of the Moon?
Good luck, and let's hope that neither of us sees this behavior again,

Audio sync prob after capturing for 10 minutes or so

I have an audio sync problem when I import into Final Cut Express. Everything is fine but lets say around 15 minutes or so there is a slight sync problem.
What I have been doing is I import into IMovie because I have it setup to cut the clips after 10 minutes. This is great because I can let it run..and it automatically splits the clips up without any dropped frames at all. The problem is I then have to drag those clips..one by one into my external harddrive. That takes time and then I have to render the audio in Final Cut Express.
I do like though that the clips are a little over 2gigs..which is good for transfering between drives and backing it up onto a DVD.
Is there a way you can do what I do in iMovie...it automatically starts a new clip after ten minutes or whatever...this way I don't have to transfer and render.

FCE does not break up clips on capture. You can capture in 10 minute chunks if you want.
The audio sync problem can be caused by a number of things most common of which is using the wrong settings for your capture, where your settings audio sample rate doesn't match your media.

Audio Render issue - Media Encoder

Hello All,
I just ran into a odd audio issue after a render. Anyone have any idea as to why this is happening? (audio file below)
Sequence is : ProRes 1080p 2997. Rendering to ProRes. Audio source is a .WAV
http://www.rtbstudio.com/Clients/AudioError.aif
Additional testing has shown that the issue only occurs when I render out of Adobe Media Encoder.
Rendering straight out of Premiere does not produce this issue.
Thanks!

Premiere 7

You are correct Jim, I was in a bit of a hurry and didn't check my language.
It is on exports. Odd thing about this, it only gave me an audio issue when 'exporting' to ProRes. I did a multitude of client review Quicktime H264's and never had the issue. Even with the 'Native Premiere Support' checkbox enabled.
It appears de-selecting the 'Native Premiere Support' option works for the prores.
Will Adobe ever address this issue? This issue makes me really nervous when exporting batches via AME.
Cheers!

Random Audio Render--deleted audio reappearing

When I adjust audio (i.e. change levels, in and out points, effects) on a section of audio that has already been rendered it oftentimes will not adjustment appropriately. It is like FCP uses the old rendered audio information and mashes it with the new. Sometimes the results are random bits of audio that pop in where they are not supposed to be--sometimes I have deleted the audio files from all tracks entirely and FCP still plays the audio like it is there.
I have had this problem for quite a while. I've deleted every render file on my computer, started new sequences, etc. This is clearly a bug--anyone found a fix?

maybe it has something to do with checking the render menu audio selections (for playback) or (item level)?

After Effects Audio Render

A few days ago I rendered a project with an audio file (a WAV file) and everthing rendered perfect. Today I tried to render again the same project, but now when I hit render, my render stays on the first frame and doesn't move from there; it freezes. And then when I hit ESC, this is what appears:
I can't render with an audio file. Even I compose a video file (with audio included) and it doesn't render.
What am I doing wrong??

Impossible to tell without seeing the files and some more info on the project. Still, if something that worked 3 days ago doesn't work now, something has changed. Check your audio prefs in AE as well as your system audio driver settings. I supect something has changed there. Maybe you ran a game and it modified some things or you enabled a feature in a media player that didn't revert to defaults and affected audio globally...

Audio Render Problem

Used to be I'd import an Mp3 music track, render it once, then could manipulate levels to my hearts content without having to render again. Now, suddenly, for some unknown reason, every time I manipulate the level, I have to render. Some setting somewhere. Any ideas?

Nor sure why you loose the render.
I'd suggest you convert your MP3 to aiff format before bringing it to FCE. Don't forget to match the aiff audio rate to your current Sequence setting, either 32 or 48 kHz.
iTunes can easily convert the file unless your audio is DRM protected.
