Slight delay on playback
I am an aerobics instructor. Imported an aerobics cd into ITUNES where perfect 8 count measures are uninterrupted between songs. But when I playback using IPOD mini 1.4.1. there is a slight delay between songs. Playback is correct in ITUNES
No, that's the usual latency we all deal with.
Hook earphones or speakers to your Playback monitor/TV and the sound will sync to that monitor provided firewire out is active.

Very slight delay in live recording
Hi.
I am running LE with an Alexis Multimix 8 Firewire control mixer. I am getting a very slight delay over the monitor speakers and in headphones when speaking into mic or playing guitar when a track is record enabled. This is annoying. I do not get this delay when using Cubase LE which came with the mixer. Being new, I guess you might call what I am looking for is a "dry" sound. I have tinkered and read the manual adnauseum to no avail. Is this due to a "processing" delay through LE? Is there a record or monitoring setting that will alleviate this problem?
Thanks,
Tom

I think I just found the answer in another thread. I turned off "software monitoring" in the audio preferences and the delay went away. What exactly have I done though in terms of input sound and what is being recorded?

Problems with the slight delay of keyPressed.
Hi all!
I just joined the wonderful sdn network, so HELLO EVERYONE :D
I studyed some java in unversity, but never in depth, and ive recently found myself yearning after it, so recently i decided to try and teach myself!
Unfortuantly ive hit abit of a problem, im trying to make a pacman game, hopfully develop it beyond the original and make it more innovative.
Ive come across two problems
1. My applet doesnt seem to have any focus until ive clicked onto it - i cant figure out what needs the focus and which focus method i should use or where the code should go!
2. Although ive got my pacman displayed with a nice munching motion (which im quite proud of ^_^ ) and he moves when the specific keys are pressed, theres a slight delay when i try and change direction, or when i first keyPress. Hopefully you can see what i mean when you run my code, or maybe you already know what im talking about!
I have a feeling its to do with the keyPressed code, since it only kicks in when the key is down, rather then when its keyDowning(if thats even a word!) is there a way to remove that delay so movement is seamless?
So id be very grateful if you could advise me on what my first mistake was, and what i could do with my second problem!
Thank you, my code is below, and please feel free to share some POSTIVE critisim, on my code, or advice on what steps to take next or in coding in general!
CHEERS!

Final Cut Pro 5.1.4 running on a brand new Mac Pro (10.5.4, 6 GB RAM, 2x2.8 quad CPUs).
When I hit "play" there is frequently (but not always) about a 5 second delay before playback starts. I haven't seen this problem yet when playing back Source-side material in the viewer.
All Media is stored on an internal 1 TB 3.0 GB/s SATA drive with perhaps 200 GB of material on it. (I.e., mostly empty). The sequence in question is very, very simple. (One video track, 6 audio tracks, no effects or dissolves whatsoever).
What's going on here? I used to use FCP on a G4 PowerMac about 8 years ago and it never had this kind of sluggishness. (Nor did my more recent G5 PowerMac).Brian,
It is a pretty small project. (DV footage). No nested sequences, no graphics at all (haven't imported them yet). This is a 2 minute promotional film. There's perhaps 30 minutes of raw footage in the project.
I excluded the drive from Spotlight at your suggestion and haven't seen any improvement. I don't know if I would need to reboot the computer, etc., to see any effect there...
I'm actually starting to think it is something to do with some of the footage. I brought in an old project and wasn't seeing the problem in that project. With the current project, the client delivered some of the footage as a DVD, and I was forced to use Streamclip to rip the footage from the (non-commercial, unprotected) DVD into DV format. The rest of the footage digitized from a DV camera. I wonder if the Streamclip footage is weird in some way that's causing the difficulty? (I've never used footage obtained that way before).
Thanks for the ideas. -
Recorded track delayed on playback
Just starting out with Logic. I'm using an Aurora 16 with firewire and a Macbook Pro. Tried to record some bass yesterday, and it seemed fine as we were recording, but the recorded track is delayed on playback. What's up with that?
What were your Buffer settings during recording? I assume you didn't monitor through Logic (Software monitoring) but directly through your Interface otherwise you would have noticed the latency while playing. So set the Buffer settings in the Audio prefs to the lowest possible (try 32 or 64) and see if that improves the issue.
Did you record with your Plug In delay compensation to "All" or "tracks+Busses" or off? Try "tracks" or "off" next time and also make sure you don't have a latency inducing plug on your Stereo outs like Adaptive Limiter or alike. -
Delay on playback when switching between Sequences (Media Pending)
Hello guys,
I'm growing quite frustrated with Premiere CC lately.
So I am running CC on a Desktop PC. Core elements are : Asus X-79 Deluxe, Intel i7 4930K, 32gb ram, Geforce Titan.
OS (Win 8.1) and CC are running on a SSD. Footage is on internal 7200rpm HHDs.
All other softwares (mostly Davinci and Red Cine) are working perfectly, fast, no crash what-so-ever. So I thought the system was working fine. But Premiere is a nightmare and I'm trying to figure out where it can come from.
Some issues appeared recently, on the latest version, and I did not have in the previous ones.
First, I was facing a huge problem when simply opening clips from the Project window into the Source player. I usually had a 30-second "Media Pending" every time. When working with 1000+ files, it was simply impossible to work. Weirdly enough, I found a trick : when opening the first clip, I would have this Media Pending issue, but (that's where it gets funny), if I did not play the clip, just stay on the first frame, and opened a second one right away, then the second one wouldn't have the Media Pending issue. As long as I stayed on Frame 1 of each clip, I could open the next one without any issue. Then, once I navigate in those "pre-opened" clip, they'd play fine, without delay. But again, if I went a bit further and opened a new clip (not previously pre-opened) I'd have to go through 30 seconds of Media Pending again. F*** annoying. But whatever, I just had to open all clips before starting editing and then it would work.
But now, I have a very similar issue when I edit further on. Especially if I have several sequences, every time I move from one sequence to the next, it would take several seconds before the video (on the Program Player) would appear. Most of the time, the player just stays black, but a couple of times, I got the Media Pending screen again.
Then, once this is passed, the playback is all over the place. The most common problem is that the video plays, but if I press stop, the cursor stops on the timeline (the UI reacts to what I do) but the video keeps playing.... and I can press stop like a maniac, it stops playing like 20 seconds later... The UI still reacts, I can navigate menus etc... but the video just keeps playing. I have to wait several seconds before being able to work again.
I've tried a lot of things : changing the footage to a different disk, updating Video drivers. I suspect it is related to a fairly new function cause I never had these problems on the previous Premieres (the pre 2014.2 version). But right now, I just missed the deadline of a client today because the program was being so slow. You can imagine I feel a bit stressed.
Let me know if you have experienced stuff like this before, or if you had any idea where it can come from, I would really appreciate your help!
Thanks a lot!
CédricYes of course, I know it's mostly the frustration talking, but unfortunately the issues with the software are important enough to affect my job a lot.
And they are still here, I'm really trying different solutions, especially since they appeared recently, they must be linked to a new feature somewhere in Premiere. Any idea what it could be? It working absolutely fine on Premiere pre-2014.2.
Now I open my almost finished sequence, and when I drag the cursor across the sequence, every time it's on a new clip, it freezes for a while. A few seconds. Then that clip plays fine. I move to another shot and it's the same, the video freezes for a while (UI still reacts normally). If I try to just press play, it plays the shots that i already when over, but if there is a new one, the video freezes, sound continues, and I can press stop as many times as I want, it keeps playing.
Once I have finally gone once over every shot, then the video plays absolutely fine. So I guess it has to do with a cache option. But tried cleaning the cache, moving the scratch disk to a different disk (now it's on a internal ssd, should be fast!) but to no avail..
At this point, I feel the last 3 options I have is :
- finish my current projects, and try an entire new workflow for the following ones, and use something else than the MXF container
- or, finish my current projects then move to Avid
- rebuild my entire system to see if that changes anything -
Hello,
I just sat down to start editing today and suddenly whenever I try to play back my sequence, there's a two-second delay. It didn't do this yesterday, and nothing has changed. I'm editing a trailer so the sequence is only 1 minute long.
I restarted the machine; no dice.
Any ideas why this would start happening out of nowhere? It was perfectly fine last night.
Many thanks for any help you may offer,
Sean
fcp 5.1.2
qt 7.1.3
2 400-gb capture drives w/ 68 and 26 gb free
Mac Pro 2.66 Mac OS X (10.4.8) PowerBook G4 667I'm going to guess that by accident last night you hit the "delay playback by 2 seconds" keyboard shortcut.
If you were sleeping overnight and also during the day, I think you need to get up earlier and get to work.
Sorry.
It might be worth checking under System Settings / Playback Control. If somehow that got set to 30 it would account for an extra second of delay after requesting "play".
For kicks, do you get the same delay with J for reverse, or when pressing J or L additional times to change speed? Or when doing anything else?
Is your project file suddenly huge, or do you have large unrendered sections or still imports? -
Unexplained video delay on playback
Hi all,
I'm experiencing a strange FCP behavior, which makes it barely usable... But first things first, here's my setup:
G4 MDD Dual 1.25GHz with RAM 768MB
I'm in PAL land (25 fps), doing DV work.
I recently found an unfinished editing project which I had started several years ago in FCP 1.2.1, and I thought it would be best to follow the common advice and finish it in FCP 1.2.1.
So I booted my G4 in OS 9.2.2 with QT 6.5.2 and I opened the project.
Here's the problem: whenever and wherever (Viewer or Canvas) I try to play a clip in FCP, nothing happens for about 1.5 seconds. I mean the playhead stands still and the Viewer or Canvas image doesn't move. Then, after that about 1.5 seconds delay, the playhead jumps to about 1 second and 14 frames (00.00.01.14) and then everything runs smoohtly until the end of the clip/timeline or until I press Stop.
However, manual scrubbing with the mouse or keyboard works just fine. No delay.
Happens everytime, with every clip, with every project I open in FCP 1.2.1. Needless to say, that behavior makes it almost impossible to edit anything.
That never happened on my previous machine, a G3/400 with Mac OS 8.6 and
QT 4.0.1 (QT version provided with FCP 1.2.1).
Seems FCP-related since when I open the capture source clips in QT I get
perfectly smooth playback right from the start.
I know it's a very old version, but I thought I'd ask anyway... Any thoughts?
TIA

G4 MDD Dual 1.25GHz RAM768MB Mac OS X (10.3.9) Mac OS 9.2.2Hi Denis,
Thanks for the warm welcome, which I appreciate even more considering how tough my question is.
Yes, I did repair permissions and trashed FCP prefs, to no avail. No anti-virus software, my drives aren't full and media is on a separate drive. I've been going by the book since day one, when I started with the G3/400.
Jerry may indeed be on to something, as the list his link points me to doesn't state FCP 1.2.5 (let alone 1.2.1) as being compatible with a G4 MDD. However, I wonder if that means it actually doesn't work on that machine or it hasn't been tested on that machine... I mean, they may just have tested/listed it on the machines that existed at or around the time FCP 1.2 was released...
It does work to a great extent. I just spent part of the evening capturing about 45 mn of footage using 1.2.5 and QT 5.0.2... It's just that delay problem that's gonna make editing a real PITA. And I haven't installed my copy of FCP 4.5 HD yet, for fear of being a little lost on account of the changes in the interface... -
Why slight delay immediately after launch?
Ever since I upgraded to Aperture 3.5.1 (from 3.4.5) and to Mavericks 10.9.2 (from Mountain Lion 10.8.5), I've noticed a slight (3-5) second delay upon launch in Projects View: the key photos associated with each project are a little blurry and only become sharp after the delay is over.
Any idea as to what could be causing this delay?Sorry to repeat myself, but try OnyX "automation" followed by a reboot, it might be a corrupt ds_store file or something else.
At least the "do it all" cocktail of OnyX may catch the problem.

Audio/Video in sync but session regions are delayed during playback???
So I have a post audio project with 189 tracks. I've worked in sessions this large before and had no problems.... I'm have audio synced to video, which playsback in sync with the picture. However, The regions seem to be off. When I playback and the playhead scrubs across a region it takes a few more frames until it playes the region.... Wow, what a tough thing to describe. It seems liike theres a delay in the session overall but the audio and video are still in sync....
I thought it could be a processing issue but I'm not even coming close to taxing any of the cores....
Mac Pro 8 core
Logic Pro 9.1.8
Thanks in advance.Hi People, i have found the answer to my question and thought i might post the cause so anyone else who gets caught can get it sorted.
The answer ended up being that i had an aggregate device as my audio interface (because i have 2 audio interfaces) and so the audio was being delayed in being processed. So i deleted the device in my Audio MIDI Setup (audio page) and thhus, its all good. Quite painfull after a FC reinstall! Ha!!

Spinning ball delay on playback ?
Anyone ever see the spinning ball when you hit the spacebar or the play button on the recorder or source window ?
Everything was fine a couple days ago, now, whenever i try to playback the source video or the timeline, there is a pause, sometimes with a spinning beach ball before playback starts.
I do use a firewire drive, but it happens on a second internal SATA drive, with the firewire drive disconnected. Also, as I said before, I have used FCP for several years, and never had this issue before. Happens on new project, old projects, whatever.
Any ideas? I have repaired permissions already.arhtur think its Tiger / FCP 5 / QT playing up...I get spinning ball on most things - timeline if left alone for a minte or so etc. never happened on 4.5 FCP, next dont be surprised if scrubbing starts to give you the ball too, and then juddery playback.
Over the past few weeks the site has been full of folks with these issues, we all hope Apple is reading and they fix FCP 5 real soon as its a lot slower than 4.5, which surely is not why we spent the bucks. -
Delayed audio playback in canvas - ProRes 5D clip
I have some 5D clips (30fps) which I transcoded into ProRes 422 in Compressor, at 48kHz. I dropped them into a ProRes 422 30fps 48kHz timeline in FCP. Upon playback, each clip has no sound for the first few seconds. The bars in the timeline are gray, so it "should" play back fine.
Mine has Firewire DV checked, but grayed out. What should it be?
At full realization that I'm going to look like an idiot, I just tried rebooting the computer and the playback is now fine. I had already checked the activity monitor to make sure I had enough RAM available, and tried restarting FCP. As I bang my head on the desk, I ask why I didn't try rebooting first. Thanks for your help. -
Is there a way to put a slight delay into hot corner activation?
I have my hot corners set up for Spaces, Expose, DashBoard etc. I find it pretty frustrating that I momentarily invoke a hot corner action every time I go for the Apple menu, or the trash, or something on the far left side of my over-populated dock. It's especially annoying when DashBoard kicks in doing this. I assume Apple made a user selectable delay on spring loaded folders to avert similar frustrations.
Is there some 'defaults write com.apple.blah...' command that fixes this?I don't know of a delay function, but you can add a modifier key to the activation.
In the System Preferences, while you are setting up that corner for activation, press the modifier key (e.g., shift) then select the function (e.g., spaces). To use it, you'd have to have the modifier key pressed BEFORE you move the mouse to that corner for activation to work. -
Tonight's Meet-Up SLIGHT DELAY (Recommend Broad St Exit 5B)
Hey Folks! Just wanted to give a heads up about Voters Rights march this afternoon. I usually take the Broad St Exit anyway, but if you don't normally you may want to consider since the march will be coming finishing up on Cherry Street.There is a chance this may not effect us at all since it starts at 5pm and they are planning on reopening streets as the march travels along the map http://www.wxii12.com/news/moral-monday-protest-march-scheduled-in-downtown-ws-traffic-delays-possib...But technically they are saying the march will last from 5pm-7pm so the worst case scenerio we start 30 minutes late. (BTW I accidentally put 6pm for the start time for meeting tonight, but as most of you know we don't officially start until 6:30pm)See you all tonight!!!

Why is there a "slight delay" after start up??
Hello all. Office PowerMac Quad 2.5, latest OS X.
The Starting Up process (Blue Bar) is really fast, but after that when it comes to the Desktop, where the Top Menu Bar, Clock etc would start to appear, there will be this "clean page of a Desktop" before everything starts to appear in place, this can take a while.
I did not use a stopwatch or anything, but that process is definitely "much slower" than my PB 12" and my home iMac G5, both of them after starting up, the Desktop "items" would almost sequentially starts to appear (in place), no much delay.
I would also like to point out a while ago, I thought I had some problems with my G5 that I trashed away the entire Cache folders found in the main Library and the other User's folder, I think.
Thanks and cheersSorry to repeat myself, but try OnyX "automation" followed by a reboot, it might be a corrupt ds_store file or something else.
