Time Stretch problem: output playback is jittery/stutters

I have a short clip within a larger project that I copied behind the original on the timeline so that I have the scene play at the normal speed, then in slow motion. The output of the stretched clip stutters or jitters (unsure of the proper terminology). This stuttering or jitters gets progressively worse with ever slower speeds. I would immediately blame the equipment if I weren't using an Intel i7 system with 3 MBs of RAM & 10k RPM drives although my video card may be considered pedestrian by some. I am using the software "straight out of the box" and have not made any changes in preferences yet.

Well, I'm hoping that, although your equipment is "straight out of the box", you've gone to Windows Updates for all of the necessary updates, downloaded new drivers from your hardware providers (particularly you video card's) and installed the latest Quicktime. Even fresh out of the box equipment is sometimes four to six months out of date.
But, that said, there are a couple of things you can do about your playback, depending on what you're seeing when.
1) If you're just playing it in Premiere Elements, your time stretched clip may need rendering. (Is there a red line above it on the timeline?) Press Enter so that it can render (the red line will turn green). This will give you a better idea of what your final output will look like.
2) If that doesn't help then, depending on how much you slowed the clip, it may help to apply Frame Blend from the right-click menu to smooth the play out.
If neither helps, it may be related to your source files. Because of the temporal compression system that MPEGs use, they don't do slow-mo nearly as well as DV-AVIs.

HT5146 logic 9.1.8 time stretching problem

Time stretch in logic 9.1.8 is not working in arrange window or sample editor.
The arrange window stretching causes the computer to process...but nothing changes in the audio track. Time stretching in the editor is grayed out along with other options in that window. I have tried to stretch mp3, wav, aiff from my samples collection and also my own recorded aiffs..also tried using different file locations on my drives..also have checked permissions and have restarted my computer a few times...nothing works.
I am using an imac from end of 2011 on mountain lion.
anyknows how to get this to work?
thanks

I think it's one and/or the other.. I know compressed files cause problems but I also think it might be a permissions issue of some kind too...
Converting to CAF in the BIN, seems to get around both possibilities... and so far, every time i have converted the resulting file works perfectly fine..
The bit of the Logic Guide that seems to be the clue is this bit...
Note: It is not possible to assign fades to compressed audio files, nor can you destructively edit them.
Found here....
http://documentation.apple.com/en/logicpro/usermanual/index.html#chapter=11%26se ction=4
and stretching seems to be distructive.... (not Flex but drag stretch...)
Whats odd is it seems to do it graphically but then as soon as you click on the region, it goes back to it's original size!

Graphical Time Stretch Problem/Bug??

Hello.
I've dragged a region of audio from the audio bin on to an audio track in the arranger. It is a kick drum track.
Holding down option and clicking the bottom right hand corner of the audio region i then proceed to graphically time stretch it by a small amount (one or 2 bar divisions).
Upon doing this logic warns me about time stretching. I click ok. Time stretching occurs but my audio region has moved forward a few milliseconds. What this means is i lose the accent of my kick drum on the first beat.
Is this a bug or some fault of my own? I am definately time stretching, not length changing. However upon going through the above proceedure the undo is titled "Undo Adjust Region Length"
It is very strange. No other users have reported this problem. Being new to logic i assume I am missing something.
I'm using logic 8.01.
Any help would be appreciated.
Thanks,
- Justin.

Hi there, this isn't a bug. I'm going to guess that there's a problem with your kick drum.
Every audio region has something called an anchor. That's the part of the wave that should always be on the beat. If your sample has some silence before the kick starts (even a relatively small amount) the silence is staying on the beat but the silence is being stretched along with the rest of the sample, making your kick even later.
Open up the audio editor for your kick and see where the anchor point is. You can find the anchor in the strip just below the wave form. Move the anchor to the start of the sound (or even a little bit after, perhaps the loudest point of the wave) and try everything again.
What happens now is that the whole wave gets stretched but the anchor point will always be on the beat.
Have fun!
Pete

Time Stretch Problem!

Using Logic pro 9.1.5 I Noticed that when I'm time stretching a track. Once finished, The Level of the track is 3db or more lower than the Original Level !!!! Does anybody know why this happens and if there is anything to do to fix this?

Well, audio is not exactly like a rubber band, I guess it all depends on the harmonic structure of your audio and the way the stretch algorithm manipulates the data, but my knowledge of digital audio processing doesn't go deep enough to fully explain this. The way I see it is that these algorithms have some sort of safeguard feature preventing the level going up - which I imagine could also happen, given the complex interactions of sound etc etc. A rubber band behaves much more predictable - it's the same basic stuff, reacting in a way that requires very simple mathematical formulae. Audio is much more varied an complex than latex.
What you could do, purely as "scientific" exercise, is to create a 30 second audio file, consisting of a constant sinewave at 1 kHz at, let's say, -6 dBfs, and see how that behaves levelwise when stretching it (try both stretching it longer AND shorter ("negative" sretching).
You can use Logics' Test Oscillator insert effect for this, it's in the Utilities section of the plugins.
To me it would make sense that these algorithms are somehow erring on the safe side - the one thing that you wouldn't want is the level to go UP and possibly clip your audio. But again, I don't know, just trying to use logic...

Anyone besides me having problems using Time Stretch/Compression?

Each time I use this feature on a voice, it ends up sound doubled in various parts of the dialogue. Any tips?
Cuzin

I know exactly where you are coming... this is 'normal' and everyone has the same problem..
Have you experimented with the different Time Factory settings?
The algorithm you set in time factory (sample editor) is the algo used in the arrange stretching.
It isn't up to scratch at the moment and I run ProToysLE in the background just for time stretching and audio timer correcting etc.
Another option is the Serato logic plugin (which also runs in Time Factory and apparently appears in the listed set of algos, though I haven't used this)
I use Melodyne for more critical things.

Time stretch to slow down motion

I am using Adobe Premiere Elements 7. When I use the time stretch to slow the motion down, my final motion is very "jerky". Any way to smooth that out a bit better?
Thanks,

How does the Slo-mo footage look in Preview?
Also remember that you are basically doubling the number of Frames.
This might also be of use for improving the results:
Set field options for imported interlaced video
In most video, each frame consists of two fields. One field contains the odd‑numbered lines in the frame, and the other contains the even‑numbered lines. The fields are interlaced, or combined, to create the complete image. Adobe Photoshop Elements includes a reverse field order preset for video imported from a hard disk or Flash memory camcorder that uses upper fields first. If your footage was captured with reverse order fields (upper fields first), make sure your project uses either the Standard or Widescreen preset from the Hard Disk, Flash Memory Camcorders presets folder. (See Create or change project presets.)
Ordinarily, interlacing isn’t apparent to a viewer. But because each field captures the subject at a slightly different moment in time, playing a clip in slow-motion, creating a freeze frame, or exporting a frame as a still image makes the two fields discernible. To avoid this, you can deinterlace the image. Deinterlacing eliminates one field and either duplicates or interpolates the lines of the remaining field.
Reversing the field dominance, the order in which the fields are recorded and displayed, may also cause playback problems. When the field dominance is reversed, motion appears jerky because the fields no longer appear in chronological order. Fields can become reversed when the field dominance of the original videotape is the opposite of the field dominance of either the video‑capture card used to capture the clip or the video‑editing or animation software that last rendered the clip. Reversing can also happen when you set an interlaced clip to play backward.
To avoid these complications, you can deinterlace the image. Deinterlacing eliminates one field and either duplicates or interpolates the lines of the remaining field. You can also set field options for an interlaced clip so that the clip’s picture and motion quality are preserved in situations such as changing the clip speed, exporting a filmstrip, playing a clip backward, or freezing a video frame.
Select a clip in the Timeline, and choose Clip > Video Options > Field Options.
Select Reverse Field Dominance to change the order in which the clip’s fields appear. This option is useful when the field dominance of the clip doesn’t match your equipment or when you play a clip backward.
For Processing Options, select one of the following choices, and click OK.
None
Does not process the clip’s fields.
Interlace Consecutive Frames
Converts pairs of consecutive progressive‑scan (noninterlaced) frames into interlaced fields. This option is useful for converting 60‑fps progressive‑scan animations into 30‑fps interlaced video because many animation applications don’t create interlaced frames.
Always Deinterlace
Converts interlaced fields into whole progressive‑scan frames. Adobe Premiere Elements deinterlaces by discarding one field and interpolating a new field based on the lines of the remaining field. It keeps the field specified in the Field Settings option in the Project Settings. If you specified No Fields, Adobe Premiere Elements keeps the upper field unless you selected Reverse Field Dominance, in which case it keeps the lower field. This option is useful when freezing a frame in the clip.
Flicker Removal
Prevents thin horizontal details in an image from flickering by slightly blurring the two fields together. An object as thin as one scan line flickers because it can appear only in every other field.
Good luck,
Hunt

I am having a problem with playback in Final Cut 6.0.6

Hello,
I am having a problem with playback in Final Cut 6.0.6 of 1920x1080 60p footage.
I transcoded MTS files shot on a Sony NEX FS100 into Apple Pro Res mov files but the
playback stutters in Final Cut and QTime making it impossible to edit. Is this because the files
are just so big the computer is having a problem processing them? If so what should I edit in to preserve the
best quality?
I am Running Mac OSX 10.6.8
2x2.4 Ghz Quad Core Intel
32 GB 1066 MHz DDR3
Admittedly my FCUT is out of date, I intend to up to X when I finish off an ongoing project.
Thanks Luci

You might consider running diskwarrior on your drive (alsoft.com). And run diskutility, repair disk. A corruption of the drive could cause problems. Also, drive speed starts to fall sharply as the drive gets full. Make sure you have a minimum of 10% free space on the drive. You might also get a utility to check the speed of the drive. I think Aja has one.
Also, do you have anything else connected to the firewire bus? If so, try disconnecting it. You might also try disconnecting ethernet and turning off your airport. Resetting your fcp preferences couldn't hurt.

My Many Irritations (story) and a New Solved Problem (video playback)

This topic is just going to ramble through the many things that have irritated me about my iPod since the purchase only three weeks ago. Don't get me wrong, though, I still love the thing. For the most serious problems, check out Numbers 3 and 11.
Lets see... where to begin...
I originally had no interest in the iPod, but some time after the unveiling of the fifth generation's new capabilities a friend of mine started talking about it quite a lot. And so, some time in early November, my hype for the video iPod had grown greatly. I downloaded Videora iPod converter and started converting music videos like crazy.
By the time December rolled in I had successfully converted almost all of my 150 or so music videos and imported them into iTunes. With Christmas coming up I was wondering if I should just ask for it as a gift, but impatience set in and I bought it on the fifth of December, and have greatly enjoyed it since.
Sounds peachy, but there's a fair bit that I left out.
Number 1. I love viewing movie trailers on Apple's website. But with the recent update to the quicktime software, it was required to get the updated version. With that came iTunes, a program that was at the time unwanted and an irratation.
Number 2. Videora iPod Converter has it's fair share of bugs. While I successfully converted many a video with it, I found it would 100% of the time fail to convert files of the .wmv format (Windows Media). As well, I would later find a more serious problem.
Number 3. On the first day of using the iPod I had a serious error. I had been watching videos just fine all day, and the iPod was working perfectly. I then chose a video to play and inexplicably the iPod froze. These are the symptoms: black screen, backlight on, no responce from controls.
Tired, as it was the end of the day, I was unwilling to go to the computer room and attempt to find a solution online. And so, I gambled that the backlight would drain the battery and hoped that upon a recharge, everything would be fine. As the backlight was illuminating my bedroom, I put the iPod in it's sleeve to dim it a bit and went to sleep.
As you can imagine, this was kind of scary. I was afraid that I had bricked my iPod on it's first day.
In the morning, the battery had died and I was able to recharge it by syncing it with my computer. After charging, I tried a few videos and then tried the offending video. Again it froze, but this time I was confident that the backlight would drain the battery and it would be fine.
I then looked at the folder wherin I had saved the converted video. Among all my other videos was the offending one. I played it in Quicktime 7, and everything was fine until I realized the length of the video was double what it should be. After what should be the end of the music video came two minutes of a white screen. The file size was also abnormally large, compared to the other videos.
It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played. Now, when converting batches of videos with Videora, I scan the file-sizes to see if any are abnormally large; after all, using the same settings on a batch of similar in length videos should produce files of similar size.
It occurs to me now that the method for resetting the iPod might have worked as an alternative to draining the battery.
Number 4. I should mention that the battery life on this thing was (for me) unexpectedly low when playing videos. I'm not saying that mine is defective or anything, but I just found that the battery runs down pretty quick when playing videos; quicker than I had thought it might. Not a big problem, though.
Number 5. In a search to find something to convert my .wmv videos to an iPod compatible format I found the ImToo converter. It works quite well, but the trial version is limited to videos of five minutes or less in length. I'm considering paying for the full version, but if someone knows of another reliable .wmv converter, I'd be glad to try that. For now, ImToo is good enough as most music videos are less than five minutes long, but I do have some other videos in the .wmv format that I would like to transcode.
Number 6. In mid December I went out of town for three days. Of course, I brought along my new favorite portable media player. Not surprisingly, the battery soon ran low and I was without my computer to recharge it. So I went out to a store and bought Apple's official USB Power Adapter. I thought it was kind of expensive, especially considering that they used to be BUNDLED with the older iPod models, but I was happy to find I would now be able to charge my iPod. Wrong. Something that was not made obvious to me by the package description (if it is even mentioned there) is that the darn thing needs the USB cable that came with the iPod. It does not come with one, and so if all you have is a wall socket, the USB Power Adapter, and an iPod, you're screwed. Unless it's the iPod shuffle, which apparantly is the only thing that works with the USB Power Adapter out of the box. As far as portability goes, I feel this hurts. I would have liked to keep my USB cable attached to my computer. After all, it is a pain to get to the back of my computer and keep plugging it in or unplugging it.
Number 7. I'm rather irritated with certain aspects of the iPod's interface considering music videos and regular song files. I spent a good amount of time adding artist and album tags to all of my music videos. These tags make sorting the videos in iTunes much easier.
First, the iPod's interface does not allow for the search of videos through album tags, but does through artist tags.
Second, going to Music>Albums> gives a long, cluttered list of Albums because of all of my music videos and one-hit songs that belong to only one album each.
I suppose there is a workaround.
Number 8. I recently bought another accessory for my iPod. The LOGiiX Amplified Fold-Up Speakers. A very attractive and portable set of speakers for the iPod. It comes with a little stand that holds the iPod in place, and works off of either 4 AAA Batteries or AC Power. Yet again, this is a product that DOES NOT come with the power adapter. Now, I think I MAY have one somewhere in my house... perhaps the power adapter that CAME WITH my SONY MD that is being replaced with the iPod will work....
Oh, and that little clip-on stand I mentioned? I expect it to be lost soon because when I fold up my portable speakers there is no way to clip the stand onto the outside of the speakers.
Now, as far as portability goes, I have to carry with me (at the most) seven things: the iPod, the headphones, the USB connector, the USB power adapter, the fold-up speakers, the little stand, and an AC power adapter.
Number 9. Minor irritation in my control of the clickwheel. After this long, I still accidentally select the wrong thing, and often take a fair time to get the highlight where I want. Meh, this one I'll figure out eventually.
Number 10. There was something irritating about entirely forgetting my login for my Apple ID and having to create this brand new one for today.
Number 11. Just today, I have come across a problem with the video not playing. I watched one video just fine, went to the Videos>Movies> tab and, as mentioned above, accidentally highlighted a video I did not wish to play and hit the Select button. Normally when this happens I wait until the video has loaded - when the screen goes black and the white Play symbol appears in the top left. But this time, I immediately hit the Menu button to go back to the Movies tab. The video's loading was interrupted and I went back to the Movies tab.
Now, when I select and play ANY video, after a noticable but short wait the screen goes black, another noticably longer wait and the play symbol appears, and then a black screen for a few seconds and the iPod skips ahead to the next video, which behaves in the exact same way.
I have powered down the iPod using the method of holding the pause button, but the problem persits.
My music videos can be played as songs by finding them under the Music tab, but no videos play as videos.
I am not at my home computer, and so running iPod updater or just trying to sync is not an option right now.
I will soon try to reset the iPod using the method described on Apple's support website.
EDIT Okay, the reset did the trick. Videos are playing fine now. I still want to share my iPod story, so I'll leave this here, but have changed it from being a question. Below are the instructions I followed for the reset.
RESETTING THE IPOD
1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.

Nice Rant session:
"It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played. Now, when converting batches of videos with Videora, I scan the file-sizes to see if any are abnormally large; after all, using the same settings on a batch of similar in length videos should produce files of similar size."
What did you expect for freeware? Nice effort but because it's free everyone thinks it's a gem. It's not. This web site has been flooded with questions that should be directed at the authors website. Video conversion and editing is not for the beginner. Sounds to me that you have a bunch of badly converted videos that are causing a lot of problems. Videora problems:
Known Bugs
Audio/Video sync
Problem - Output files can be out-of-sync. While no set pattern has been established, it seems to be more frequent with input files of 23.976 fps, non-DVD rips, and WMV/MPG filetypes.
Workaround solutions - Try the custom option '-async 1'. If the disconnect gradually increases over time, setting 29.97 fps sometimes gets rid of the problem regardless of the input fps. You can also use AviSynth to assume the FPS and have the audio sync to that. If it's a sudden disconnect, check your VOB Cell settings in DVD Decrypter settings per this thread. Otherwise, test with an AviSynth script per the DaProphecy's method in the FAQ. For non-DVD files, PSPVideo 9 may be a good short-term solution until the converter stabilizes some more or try something like AviDemux.
Audio track not getting picked up
Problem - The IFO stream rip is fine, but the converted file has no sound. The debug info showed to audio track getting picked up. The most obvious case with this is the Madagascar DVD.
Workaround solution ideas - Test with an AviSynth script per the DaProphecy's method in the FAQ (untested). Use a different DVD ripper.
Program doesn't start (.NET issue?)
Problem - Converter errors upon starting with an extended dump.
Solution ideas - Update .NET framework (in all languages you're using!) to most recent solution. Clean out registry. Neither of these have worked for some.
Progress meter incorrect
Problem - During transcodes, the progress meter can be incorrect; thus, transcoding continues after the meter hits 100% and time remaining is zero. People have been seeing this more often with VOB files and/or the H.264 codec.
Workaround - Figure out the length of your movie in seconds and compare that to the 'Processed' field. A 2-hour movie will not finish until Processed hits 7200 seconds.
Artifacts (bad video quality) in darker scenes
Problem - Scenes with darker background colors tend to have more artifacts (blocked video). It's much more obvious on the iPod, so this may be an Apple firmware problem.
Workaround ideas - Use a VBR setting (FQ->VBR, two-pass A->VBR) to improve video quality. The custom option '-mbd 2' might help.
Desktop icon
Problem - When installing, the desktop icon does not appear/stick when using lower color setups.
Workarounds - Select a 32-bit color scheme in your desktop settings, or change the icon in the shortcut.
Profile changes don't always stick
Problem - If you make a change to a profile, click apply, and immediately trancdoe with that profile, the transcode might not use the new settings.
Workarounds - Once you click apply, swtich to another profile and back again to make sure the change is still there. If that doesn't work, create a new profile.
Can only install/use with admin rights
Problem - There have been reports of non-admin users not being able to use the converter.
Workarounds - Separate installs or give all users admin rights.
Who in their right mind would use a program that has these many critical bugs to convert files for the IPOD. People who are cheap, kids with no money and people who are just plain gullably.
A little research and downloading a trial from this site would have solved your video problems early on;
http://www.divmm.com/
The 5th Gen IPOD was designed to support video content that was purchased on the ITunes web site. For everything else, you are on your own.

Time stretch has stopped working in Premiere Elements 13.

I've downloaded the latest Adobe updates. I am using a Windows 8 64 bit computer. I have previously (in the last few weeks) used time stretch to speed up and slow down without any problems but now I can't get it to work in any of my projects. All video files shot with an iPod Touch or iPhone. Has anyone else had this problem? Any ideas on how to fix it?

Chris
As a point of reference for your Premiere Elements 13 question, I have a iPod Touch 4th generation (H.264.mov 1280 x 720 @ 24 progressive frames per second), and I have no problems using Time Stretch or Time Remapping in a 13/13.1 project or other versions.
I would invoke the interference of a possible variable frame rate rather than a constant one involved with your particular type of video (from iPod or iPhone) and Time Stretch, but I am not having any problem with my iPod Touch video (with minimal variable frame rate) and Time Stretch in Premiere Elements. If you want to explore that idea further, you could convert your video's variable frame into a constant one using the free HandBrake program. Then import HandBrake's H.264.mp4 export into your Premiere Elements 13/13.1 project and determine if you can then apply Time Stretch to that clip.
Have you applied the Shake Stabilizer to your clip before trying to apply the Time Stretch? For that matter, what effects, if any, have you applied to your video clip before trying to apply Time Stretch to it?
All of the above is based on Time Stretch no working for you in a new project with new source media.

OFT- Problem while Playback in Oracle Apps 11i

hi,
As earlier Oracle E-biz Application are not working in OFT8.5 but now in the latest version OFT9.0 as per the information it will work fine.
But i'm facing the problem while playback the Oracle E-biz Application.
I have recorded Order Management Process in Oracle Apps11i. At the time of recording its work fine.
Steps which i had done
1) Login into the application
2) Click on the Responsibility Order Management--> Sales Order
3) It opens the external Applet window
4) Open the Sales Order Form where i enter the Customer Name and add the line item for the customer and then book the order
Stop the Recording and then playback the script
It works perfectly fine till step3 but on Step4 what ever the action user had done on Sales Order Form it is not playing back that action and just close the form and generate the Pass Result.
So i want to know why it is not playback the action which user had done on the form.
I really appreciate if any one can give the solution to the problem

Thiru,
Which concurrent manager consumes the CPU usage? Are you able to identify it?
Any errors in the CM log file? Did you try to start the CM with diag=y and see if any errors are reported in the log files?
What happen to the CPU usage when you stop the CM?
I assume that you are running Purge Concurrent Manager/Requests on regular basis, so this should not be an issue here.
Please review the following notes, and see if it helps.

Picture stretched after outputting edit of Red One footage

I exported edit of Red footage to self contained Quicktime and movie looks beautiful. However, when I used Quicktime file as source in DVD Pro or Compressor, the picture is slightly stretched vertically and there is bad artifacting. I noticed that the Quicktime file frame size is 2048x1024 (2:1 aspect ratio). I used log & tranfer ProRes 422 (16:9 aspect ratio) to capture footage and same sequence settings to edit. It looked great in FCP. What the heck am I doing wrong?! Why the difference in the aspect ratios?

Actually, I have been informed that the RED whitepaper I used to guide me through the process of ingesting and editing in FCP was incorrect. They assume that everyone shoots at a 2:1 aspect ratio. My DP shot at 16:9. So, per RED instructions, I customized a ProRes 422 (HQ) codec by changing the aspect ratio to 2048x1024 (2:1 ratio)....WRONG!! If I had been more experienced, I would have questioned that spec immediately. FCP compensated by cropping the top and bottom. I didn't notice the blue guides missing at the top and bottom until someone asked me if I could see them. In short, I've solved the stretch problem. But I still have really bad artifacting in the MPEG2 files created for DVD. I'm trying to figure out why that's happening. Also, I uploaded a web version of the short film and heard ringing in the soundtrack where there was music playing. My audio in the FCP edit is at 48Mhz and the output file is 44Mhz. Could that be a problem?

Time stretching a piece of audio in LE7

I've been using Cubase for years and since I have been doing alot of remix work lately alot of the songs are being sent have been in Logic so I got a copy of Logic Express and I'm able to navigate my way around the basics with no problem. In Cubase SX3 -or CB4 you can time stretch a sample from lets say 124 to 126 bpm. The only thing I see in Logic is the time machine? Is this the way to do what I need to do? I know, I know, read the manual but since I have to work quickly I thought I'd ask here. Any help?

Choppy or Digitized Audio w Time Stretch

Hi Guys,
I've got some audio I've been chopping and time stretching (voiceover to replace a video with poor audio). The VO was recorded in a 96kHz 24bit WAV file, and sounds great when I first played it. However, after I've been chopping (with the blade tool) and timestretching in STP, I'm finding that the audio now sounds digitized or choppy.
Does anyone know what's happening here and what I can do to fix it?
You can get a better idea of my process here. . .
Thanks,
Lawrence

Varispeed only works on the Masterbus, the final output of all tracks. Bouncing the output leaves you a 2-track master.
It's not an easy task because for one, your software tracks are MIDI based, their output is indeed audio but input is MIDI. To use Varispeed you would have to individually bounce each track/take, a mammoth job.
Perhaps someone can help you with Flex which may be you're best bet but is something I don't use very often.

Time out problem while uploading large bpel processes into oracle soa suite

Hi everyone,
I'm using oracle soa suite 10.1.3.4.0 and I'm encountering time out problem while trying to upload a 5MB bpel process into my bpel process server located in the LAN network. The error is coming from apache common file upload.
Is there a way to increate the connection time out for oc4j to avoid this problem?
Thanks for any help.
Regards
Esfand

Hi Marc.
Thanks for your reply. I increased the transaction manager time-out but still I have the same problem. I believe this is something related to oc4j settings and related to upload bpel process. here is my stack trace output:
79: A problem occured while connecting to server "192.168.0.12" using port "8888": bpel_JazbModaresJadidBPEL_1.0.jar failed to deploy. Exception message is: javax.transaction.RollbackException: Timed out

The bpel jar file is about 2MB and is uploaded from my machine located in the same LAN.
Any hints?

Poor Results from Time Stretch

Hi all,
So on a number of occasions, I have tried using the Time Stretch feature in Soundtrack Pro, but nearly every time I use it, I get noticeably poor results. For example, if I take a 31-second soundtrack and squeeze it to 30 seconds, the playback sounds very choppy. The same happens vice versa when I stretch audio by small amounts. I find myself having to do this function in Adobe Soundbooth instead. I really like Soundtrack Pro, but it seems that this feature is inferior. The funny thing is, I've seen tutorials online about this feature, but I've never seen the people giving the tutorials have any issues. Does anyone encounter this same issue? And, does anyone know if there's a fix for this situation?
By the way, I'm using Soundtrack Pro 3.0.1, and I'm running it on a Mac-Pro 12-core with Mac OS X 10.6.6.

I've done this all the time and always had good results... And I've been able to stretch quite a bit... My audio has always been 48K, 16 bit.

Time Stretch problem: output playback is jittery/stutters
