Audio delay when exporting

iMovie version: HD 6.0.4
Movie consists of approx 20 clips, (animation content (.mov files) and video content), with extracted audio and recorded audio direct into iMovie. It plays perfect in iMovie and will work fine when imported to iDVD and imaged. The problem starts when I try to export it as a smaller file for web streaming etc. What happens is some audio content is delayed and subsequently starts at the wrong time. The first couple of minutes are OK then it all goes wrong. I have tried; creating a new file, extracing ALL the audio and placing in one track (strangely when I move all the audio to one track and check off the empty track whatever audio was in that empty track still turns off!), exporting as .wmv and mpg, tried expert mode - tried everything and STIL the same audio content delays at the exact same moment. This work was created with children as a school project and need to upload to a website for them. I have also tried importing to iMovie 08 but I lose all the imported animation content - it will only import the video even though the animation content was a .mov file. Hmmmm. Any ideas from anyone??

Audio Delayed When Exporting To Camera

When exporting the movie to my camera, the audio is not quite synced with the video on the Mini-DV tape. I have determined the offset to be about 8 frames. If I then import that video, extract the audio, and then move it to the left 8 frames, it is then synced with the video again. If I encode the project with Toast after I have it synced, and then play the result on the Mac with the DVD Player, it is fine. But if I export it to the camera again, the audio is shifted again on the Mini-DV tape. I have a G4 dual 450 Mhz running OS 10.4 (the latest) with the latest version of iMovie and exporting to a Sony DCR-TRV900 via the firewire.

"..When recording it back to Mini-DV tape this way, is there a significant amount of loss of data even though it is coming over the firewire connection vs the normal export function?.."
No data loss, Gary. This is the proper way to export your edited movie.
You DO get data loss when transferring to a DVD, as a DVD is encoded differently from DV ..the MPEG encoding of a DVD involves compression of the data, leaving only information about the differences between frames of video, instead of keeping the content of all the frames.
You DON'T have any such loss when exporting ('Saving') back to miniDV tapes, as the exact same data which was copied from the tapes, when importing into iMovie, is sent back out to a tape.
There's no data loss, and there should be no audio delay. You can then import again from such a tape and there'll still be no loss. But re-importing from a DVD will produce data loss, as the decompression from MPEG to DV cannot completely rebuild all the data which was in the compressed MPEG data stream on the DVD.
So save your edited work back to tape, Gary, in case you ever need to 'reprise' it, and only create DVDs for sending through the mail, or to present your video with fancy interactive menus, or so that you can easily find particular 'chapters' in your video.

Audio delay when call is answered, CUCM 8.0

I have a client who is reporting an audio delay when a call is made to an external number. Call setup is fine and ringing begins immediately after the last digit is dialed. When the called party answers there's a 1 or 2 second delay before either party can hear each other.
Outbound calls are routed to a SIP trunk. I am suspecting that an MTP is required but checking that off causes all calls to fail.
I then discovered that the only MTP defined in CUCM is the default and this is in a different device pool than the SIP trunk with the delay issue.
Before I got through a possilbe hardware purchase (router, dsps, etc.) for the site with the problem I was hoping someone could confirm that this may in fact be the issue.
Thoughts?

Under older versions of CUCM, you can set that same parameter as a global Service Parameter for the CallManager process.You can try that. Newer versions pushed the setting down to the individual trunk level. Be aware the global setting will affect all calls on all SIP trunks, so test carefully after the change.

Audio Sync when Exporting Using Compressor

Hello!
Having an odd situation. Project in FCP 4.5 the audio is sync'd just fine in FCP export using Compressor and the audio is delayed about 5 seconds...so the video footage starts and about 5 seconds later the audio starts. Now, in the same project I have other footage and exported the same exact way without issues - I have no idea why this particular footage would be an issue! Because Compressor is exporting these files with the audio and video as separate files I am seeing this issue when the file is in DVD Studio Pro - but again none of the other files that are being placed on this DVD are having audio alignment issues...so this is not making sense.
I am not 'new' at this but I am no expert either - my main gig is audio - so I could really use some help.
Any suggestions? I am not sure what other information someone would need to help so ask away.
Thanks in advance!

Well I REALLY need some help with this one! I have tried so many different 'work arounds' without success. As mentioned in my first post the audio is not sync'ing with the video when exported. I have tried Exporting the file in QuickTime, I have tried using Compressor again exporting just the video then the audio - pulling it into a new session and lining it up again but everytime I pull it the newly exported file into a new project and render it FCP crashes not allowing it to render (nice!). I actually started from square one capturing the video footage again and assemble the project again without luck. I simply cannot believe what a pain in the arse this is!! I need to get this project done and it simply won't do it.
Where are my blood pressure pills????

Audio delay in exported movie. Help!

I have hdv video that I captured in premiere. Watching the imported video, there is no problem. But when I try try to export the movie to anything, there is a significant delay in the audio. Windows movie maker actually can read the original and when exported, the movie maker file audio matches the video (although movie maker does not maintain the proper aspect ratio).
Am I missing a setting somewhere?
Thanks

Sorry.
Premiere Pro CS3
Alienware MJ12
3GB Ram, 2 HDD
Video originally recorded on Canon XH-A1
Video captured in premiere from Sony HVR-M15U
Video is NTSC 1080i 60
Project settings are HDV 1080i
original and exported video go to default my documents folder
I just import the mpeg2 file into the composition, drag it onto the timeline and then try to export it. I've tried exporting to different formats and with different settings, but always have the same audio delay. The original mpeg2 file plays fine in media player.
Thanks

Reports output delayed when exported to Excel using OLE2

Hi All,
Platform - Oracle Application Server 10g Release 2 10.1.2.3 on Windows 32 bit.
The report output is getting generated in a minute when exported to PDF i.e destype=cache & desformat=pdf. When we generate the output to excel is considerably delayed. It is taking time and internal server error is occuring.
1) Report developed with simple query
2) Used RPT2XLS procedure which uses OLE2 builtin to export report output into excel.
3) Called RPT2XLS.run procedure in After-Report trigger of the report.
4) We have relased all memory objects in the RPT2XLS package after exporting data and there is no EXCEL.exe running once the file is generated.
System parameters used in the URL.
. destype=file
desformat=pdf
CONTAINSOLE=yes (Required for exporting OLE2 objects into Excel in report)
desname=path & name of the file.
I have gone through the tuning documents for reports server and increased minengine, maxengine and initengine parameters of the reports engine and also changed maxconnect and IdleTimeout parameters in reports server configuration file.
What might be the reason for delaying in the output of the reports when exported to Excel. Can the guys with special knowledge on this area help us in getting out of this issue.
Thanks in advance.

hey all,
Thanks everyone for the reply.
I am using the foloowing field cat:
l_col_pos = l_col_pos + 1.
    wa_fieldcat-col_pos = l_col_pos.
    wa_fieldcat-outputlen = 32.
     wa_fieldcat-fieldname = 'SOLLWERT'.
     wa_fieldcat-inttype   = 'P'.
*    wa_fieldcat-tabname = 'i_final'.
    wa_fieldcat-seltext_l = text-t11.         "Target Value
    APPEND wa_fieldcat TO i_fieldcat.
    CLEAR wa_fieldcat.
I have use this also in the field cat but stil i get space in the excel header.
wa_fieldcat-REF_FIELDNAME = 'SOLLWERT'.
*    wa_fieldcat-REF_TABNAME = 'QAMV'.
Also the space comes with the descrip[tion in the cell of excel.
its like [space Target Value] and i dont need this Space.
I have also used wa_layout-colwidth_optimize = 'X'. but it doesnt wrk.
Please suggest

Is it possible to retain multiple audio tracks when exporting?

While ripping my DVD collection, I've wanted to add a purchased RiffTrax (see www.riftrax.com) to the movie as another audio track. I've been successful, but it took the following steps:
1. Encode the movie using Handbrake, open the resulting m4v file in Quicktime Pro
2. Also in Quicktime Pro, open the Rifftrax aac file I created and add it as another audio track in the m4v
3. Save the m4v as a Quicktime mov file
4. Use Handbrake again to encode the mov file into an m4v file, including my added audio track
The reason I have to do step 4 is because if I were to export an m4v file directly from Quicktime Pro, it would compress all of the audio tracks into a single audio track. It would save a lot of time if Quicktime could export multiple audio tracks, at least when exporting to formats that can handle them. Does anyone know if this is possible?
BTW, if anyone wants more details into how I create the RiffTrax aac, just ask.
- Jake

I've answered my own question, it was a lot easier than I thought. After the first encoding by Handbrake, there's really no difference between calling it a mov file or m4v file. I can change the file extension at will and there's no need to do an export that mashes the audio tracks. It's only AppleTV that needs to see the m4v file extension, Quicktime and iTunes doesn't seem to care one way or the other.
Thanks for letting me think out loud.

First four seconds of audio missing when exporting project as MPEG2

Hello all-
When I export my project from FCP (using version 6.0.6) using Compressor's (v. 3.0.5) MPEG2 Program Stream setting, everything works fine except for one slight problem: the first four seconds of audio are missing. I've looked back over my timeline (NTSC-DV with 4 tracks of 48khz 16bit audio), everything is fine, and the audio exported just fine using the H.264 codec. I've tried everything I can think of. Any suggestions?
Thanks so much,
Brett

Well I REALLY need some help with this one! I have tried so many different 'work arounds' without success. As mentioned in my first post the audio is not sync'ing with the video when exported.

Audio Glitch When Exporting Movie Files in iMovie

I've split ambient audio from my footage and restriped a music track over. When I playback within iMovie, it's fine. But when I export the movie out, the are still remnants of the original audio in the playback. How do I get rid of this glitch?

Is it possible that you are running iMovie 09 (which is Version 8.0.6)?
There is a glitch in iMovie 09 where if you use sped changes (fast motion and slow motion) and choose custom percentages like 38%, 59%, 133%, it will cause unpredictable audio artifacts when you share.
THe solution is to change all your speed changes to one of the presets, like 25%, 50%, 100%, 150%, 200%, 400%, etc. These are the tick marks on the slider.

Losing audio quality when exporting from premiere pro

I have now had this happen with two different videos. I play the video in premiere pro and the audio is fine. I export the video and lose most of the quality of the audio portion. One project is a music session when exported I only get the main vocal the drums aren't audible only a buzz sound is made where the kick drum would usually come in. On another project is a thank you video for a family member and the audio is distorted after being exported. The audio sounds fine inside of the session. Once exported the audio will still work fine on my computer and my iphone 5s as long as I'm wearing headphones, once I try to play the video through my iphone 5s speakers the audio quality is gone, making the noises as previously stated. My iphone can still play other tracks fine but videos and audio exported from Premiere Pro are distorted. Any advice on how I can export the video so I wont lose audio quality when playing the video on an iphone? I know it's not my iphone speakers, they play other songs just fine.

The source files as far as the audio goes are wav files that I've pulled off of my desktop. My sequence settings are 1920 by 1080 at 29.97 frames per second. The export settings are H.264 with the preset YouTube (HD 1080 29.97 FPS) and I've also tried HD video 1080p 29.97 FPS. If this isn't enough information please let me know I'm in the learning phase. Audio wise the quality is set to high and I'm exporting at 4800 kh and a bit rate of 190. I've also tried a bit rate of 320 and 264 I think it is and still had the same problems. Let me know if I need to do screen shots I really want to figure this out.
Thanks for your help!

Best Codec for good audio/video when exporting to 3G in FCP

I have FCP 6.06. I have a few videos I've tried converting to 3G using Quick Time Conversion and every setting: Default, 3GPP - Release 5, 3GPP2 - Release A, 3GPP - Mobile MP4, 3GPP2 - EZmovie and AMC - EZmovie. Every one has blurry video and poor quality audio both when I play it on my computer and after I copy it to my phone. Any ideas why and how I can improve the quality of the video and audio which looks good in FCP before conversion.

Don't use FCP for delivery compression. That's what Compressor's for.
True, but the same options will be available from within Compressor. I've never had to export to 3G and I can't test it at the moment. Hope you get better answers.

Extra Audio Frames When Exporting Video

Does anybody have the issue of extra audio frames being added when exporting a video. Every time I export, the audio adds like a 2 second handle. Very strange.

The best advice is to tell them their work is coming back non-compliant and you can't have that. Let them figure out why and solve it. (That's is part of their job, after all.)

Having difficulty with multiple audio tracks when exporting

Hi,
I am trying to export a couple of sequences to send off to a friend. I've tried sending it to iDVD as well as sending to print to video. When I play it on the computer as a quicktime movie every track is there for the audio ( 6)
When I print to video to a dvc tape. All 6 tracks are there. When I then tried to record to a dvd on a dvd deck I only have 2 tracks of audio. Same with iDVD. Is there a button I didn't push. Did I push a button I shouldn't have? These are the questions I need answered. What have I done wrong. ANY help or SUGGESTIONS would be greatly APPRECIATED.

Bonjour Michael,
Thanks for the suggestion but when I did that I then had no sound. What did I do wrong. Is there another step?
thanks,
jenn

Quicktime Pro doesn't hold audio levels when exporting (or "sharing").

I just upgraded to Quicktime Pro for one reason only: to add my music to an exsisiting video (that has it's own embedded dialog track) and posting to a webpage for review. Adding my music is easy. Setting the level of my music is easy. Saving and reopening with everything intact is easy. The problem is when exporting to another format. I've been choosing the preset called "Braodband Medium". It's the h.264 codec and AAC audio etc...
After the export, my music level has been "bumped up" to 100% - drowning out the dialog track. I've tried it on 3 different Macs with the same result. Does anyone else have this problem? It seems like a glaring problem that needs fixing.

Confirmed.
Export your original two track file to your required settings (Broadband Medium), add (scaled to selection) your second audio track, make the volume setting adjustments (Movie Properties window) and Save As.
QuickTime files can have up to 99 tracks.
