Controlling Speed of audio and video playback ?

Hi!
I would like to know if there is (or will be) a way with
upcoming Flash CS4 or even with Adobe Flash Player 10 capabilities
(or even with Adobe Pixel Bender) to control the speed of an audio
or video playback.
For example being able to play some sound slower or faster
and even adjusting audio pitch (and other audio filtering).
It's been a while that I've been looking for this (back to
Flash Player 6 when Flash was part of Macromedia) and with all
progress achieved since then I hope there is some accelerate and
decelerate feature now.
Please let me know about it.

Audio and video playback stuttering...sometimes

I'm having issues with audio and video playback stuttering at times in several applications. It's the same kind of skipping or stuttering in each application, whether it's iTunes (version 10) or YouTube or Netflix (Safari). I can also hear it when I'm just adjusting the volume via the keyboard, the "clicks" stutter.
I'm not running anything other than iTunes and Safari at once, the iMac has 2 gbs of RAM, it's running Snow Leopard. It also will work sometimes for a while. I just can't figure out why it will work sometimes and not others. Any ideas about what the cause may be? Quicktime X have anything to do with it?

Quicktime wouldn't work either.
Until you max out your ram, you are pretty much stuck between a rock and a hard place. In the meantime, make sure you have the latest versions of
Adobe Flash Player

VLC Media Player

I'm noticing that in general it's running extremely slowly now, even with only the browser running.

Audio and video playback latency ,since windows 10 help please

hi everyone I'm having a problem with my laptop ,video playback is lagging and sound to , sometimes making robotic sounds, and it all started when I upgraded to windows 10.my laptop: Lenovo ThinkPad x220 intel core i7 2.7 GHz processor 8 GB of ram previously had windows 7 pro now windows 10 proI tried resetting my computer , you know to have it clean and fresh, I thought this might help , maybe some old programs from windows 7 were causing this problem , but it didn't help , I also tried disabling and enabling the drivers from the device manager , is a trick I found on youtube , but it didn't work , I'd be very thankful if you could give me some advices .

Can you try disabling the Ethernet adapter in Device Manager?

Audio and video playback from the internet.

Hi all, I am just learning on my computer so i am afraid you will have to bear with me !!! I have just visited the BBC News homepage and could not play any of the video clips or radio clips on offer, the error given was that real player was not installed, I then followed the instructions and appear to have sucessfully installed real player but still no joy on playback. What am i doing wrong ???

I experienced the same problem with audio (haven't tried video) and I don't have a complete answer to it, but if you download Real Player you can listen to the audio stream if you click on the link "Listen using stand-alone Real Player".
For a more complete solution, I'm waiting for the next version Firefox which promises to be compatible with Intel iMacs.

Loss of Audio and Video Playback

Hello.
I am currently using Adobe CS6 Production Premium on Windows 7 Ultimate. I have updated alll of my sound card drivers.
While in Premiere Pro, if I unplug my headphones, so that I can hear through my speakers, the video and audio playback hangs. In order for both playbacks to work again, I must restart the program. The program itself does not freeze, as I am able to drag clips as well as save the project.
Any help would be appreciated.
Thank You.
Tyler

Variable speed on Audio and Video

I want to do a variable speed ramp using video and audio, but when I use the graph it only applies variable speed to the video ( it does constant speed fine to both)
Any help ? Thanks
Deyson

I see other people have this problem but I can't find the solution. It's occasional buzzes on the speakers when I'm watching a video. The mouse momentarily freezes--fraction of a second--and the video jumps. Sometimes the busses are pretty quick and have a slightly different tone.
Any help?

Clip audio and video playback out of synch

I've noticed that everything in FCP X is slightly out of synch. Just enough to be noticeable. I thought it might have been the time taken for the sound to travel the length of the church (recording from a camera mic) but I shot some green screen yesterday and even that is out.
The same hardware was used ok with FCE-4 - the Audio i/f is FW-400 and on same bus as FW drives.

Hey Andy, (cue whistling theme music)
Thanks for your informed opinion. Interesting that Apple released FCPX in it's current state rather than wait for the release of Lion. Seems like the core technologies now bundled with the app would make a significant difference running natively.
I'm an audio guy... the next release of Logic Audio is going to be version X, I'm just hoping it's not going to be Garageband Pro.
The reason I was expressing doubts about an OS upgrade making a noticeable difference is.... I heard the same thing about Snow Leopard. As it stands now I have two clients trying to run the latest version of Logic Pro on the current release of SL (10.6.8), the results are not good, the Logic Pro forum has many users unable to get Logic to even boot without crashing.. I'm waiting to hear from support. It seems like the OS is ahead of app development and things are breaking.

IMovie will not import or play the clips at the proper speed and the audio and video do not match up.

i have a samsung hd camcorder. it records at 40 fps, but iMovie will not play the clips at the proper speed and the audio and video do not match up. I have tried to record at standard quality to no avail. Help. thanks in advance.

samsung sc-hmx10c ntsc
im guessing that is the speed it records at due to the fact imovie puts a blue 40 at the top left corner of every clip i import.

Logic 9 Audio and Video sync at beginning timecode, but not in the middle of playback.

Hey Guys,
I'm working on a Trailer for a feature length, and my video playback is pretty screwy.
I've double checked the video to be 23.976 framrat and set my project to that framrate, and I've done what I normally do with bitrate and sample rate. But currently my audio and video will not sync together when I start playback in the middle of my project.
Playback works fine in the start of the project, and everything looks and sounds great. But as I'm writing and edtiting further on in the project all the audio gets out of sync. If I start the project from the beginning, then all of the MIDI for the whole piece registers as synced, and the project sounds and looks great the whole way through. The problem comes from starting playback anywhere in the middle of the project.
I'm working with a .mov file (1:45 minutes); three .AAC audio files, and plenty of thrid-party plug-ins. 10.7.5 Mac OS X, 2.2 GHz i7 core, and 4GB m
of memory.
Any thoughts?
Thank you!

Thanks guys for the input.
I am using an Aurora 16 via firewire
I did change my buffer settings and that seemed to fix it but now I am at 128. I moved over to the aurora because I preferred the extra headroom. I guess I should have stuck with the apogee.
Tonight was the first time I had the opportunity to do a full tracking session with 9. I have been doing quiet a bit of mastering with no issues. Quiet a few issues. Everything from logic quitting to it just locking up. So far.....a pretty bad experience. I wonder if it could be Snow Leopard.......

How to synchronize audio and video rtp-streams

Hi everyone!
I've tried to make one of the processors, processor1, control the other processor, processor2, with processor1.addController(processor2) but I get a
javax.media.IncompatibleTimeBaseException. I need to synchronize audio and video rtp-streams because they are sometimes completely out of sync.
In JMF API Guide I've read:
"2. Determine which Player object's time base is going to be used to drive
the other Player objects and set the time base for the synchronized
Player objects. Not all Player objects can assume a new time base.
For example, if one of the Player objects you want to synchronize has
a *push-data-source*, that Player object's time base must be used to
drive the other Player objects."
I'm using a custom AVReceive3 to receive rtp-streams and then I create processors for the incoming stream's datasource's, and they are ALL PushBufferDataSource's.
Does this mean I can't synchronize these. If so is there any way I can change them into Pull...DataSources ?
How are you supposed to sync audio and video if not with as above ?

You can't change the timebase on an RTP stream because, for all intensive purposes, it's "live" data. It plays at the speed the transmitting RTP server wants it to play, and it never gets behind because it drops out of order and old data packets.
If your RTP streams aren't synced correctly on the receiving end, it means they aren't being synced on the transmitting end...so you should look into the other side of the equation.

Audio and Video syncing issues

I have a video file where the audio and video file are normal when I play the clip in Quicktime. When I import the file into an FCP project and drag it into the timeline, the audio and video are no longer synced. My sequence setting is ProRes422 as is my video clip. The only difference I can see is that my clip is 24 bit integer and the sequence is 32 bit floating point. Although, this is my 50th project capturing old BetacamSP tapes and all my projects say this and I haven't had a problem until this particular file and not afterwards. Any thoughts?

There you go then ... make sure you monitor audio and video by the same path ie both via the Kona card or both on the Mac ... or use the Playback Offset to compensate for the delay between the Canvas window and the Kona output.
From the manual:
To set the frame offset between the computer display and the external video and audio outputs
Choose Final Cut Pro > System Settings.
Click the Playback Control tab.
Enter a number of frames in the Frame Offset number field.
Frame offset can be any whole number between 0 and 30. The default value is 4. For example, if a video monitor connected to your DV camcorder shows your program four frames later than your computer display, a frame offset of 4 will synchronize the two.
Note: Depending on your external monitor configuration, you may need to experiment with frame offset values to synchronize the external monitor and the computer display.
Click OK.
Play your video in the Canvas or Viewer and compare the video offset between your external monitor and your computer display.
If the computer display and external monitor are still not synchronized, repeat steps 1 through 5 using different frame offset values until the display and monitor are in sync.

Selected audio and video devices may not match

Hello - I was able to Print to Video w/no problem, from my Mac Book Pro, to my Panasonic PV-GS320 w/no problem. Now, all of a sudden, when trying to do this, I get this msg.:
'The selected audio and video devices may not match. Please verify that the a/v outputs are externally routed to the intended device(s).'
Not sure what happened, or what changed, but here is my setup:
Sequence & Capture Presets are both: DV NTSC 48 kHz
Device control preset: FireWire Basic
Video Playback: Apple Firewire NYSC (720 x 480)
Audio Playback: Default
Like I said, I don't know what got changed, but, it was working before - hope someone can help, thanks so much!!
Kristina

I think I found the problem...I had forgotten to switch my Device Control Preset back to FireWire, from the previous non-controllable - thanks so much!

Premiere Pro CS6 importing/ audio and video problems

I recently recorded gameplay from my xbox, when i open this recording using windows media player it states that the video is 3 hours 30 minutes long, which is correct, when i then import this into premiere pro, premiere pro changes it to be 5 hours and 44 minutes long, when i then play this back it plays in slow motion and audio and video start to desync, i thought it may just be the source editor playing up so i made a clip and put it into the timeline and it still had the same outcome. The speed/duration are still on 100% so im not sure what to do, anyone have any idea as to what this is, or why it is happening?

What are the attributes of your PVR video...
specifically, is it variable frame rate?
