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?

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.

If you have a red line over the timeline after importing a video and before adding any effects... your project is wrong for your video... read above about codecs
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project

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.

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.

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?

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?

Audio and video out of sync after import

I'm trying to bring some H.264 video into a Premiere project. But when I place it in a sequence (a sequence that is created based upon this very clip), the audio and video are about a second out of sync. (It's also odd: no amount of adjustment will bring them in sync. Seemingly the video is running at some variable rate that makes synchronization impossible...?)
As a test, I tried bringing my video into iMovie, and it works just fine there. But I don't want to use iMovie: I want to use Premiere.
Any ideas?

Why do my audio and video start in sync, then quickly go out of sync?

I've just installed Windows 8 and also purchased Premiere Elements 12.
I've also got Windows movie maker.
When I play my clips in Premiere Elements, they audio and video start of synced, but quickly go out. This doesn't happen with Windows Movie Maker and I had trialed some NCH video editing software also and didn't have that problem.
can someone tell me what I need to do to get this working right?

The first thing that we need to know are the properties of what you are putting on the Timeline. What works in another software does not necessarily work in Premiere Elements. Each program has its own supported formats.
a. What is the file extension for this file? .MOV or .MP4?
b. Does the iPad describe it as 1080p or 720p?
c. If you open Premiere Elements 12 and go to Edit Menu/Project Settings/General, what do you see for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio, even if those field appear to be grayed out.
Two immediate troubleshooting avenues are going to be in the direction of...
a. Project settings not set up to match the properties of the source from the iPad. Then we would start a new project and set the project setting manually before importing your video. Details for manually setting the project preset are in the following.
ATR Premiere Elements Troubleshooting: PE11: Accuracy of Automatic Project Preset (New Project Dialog) Setting
b. The iPad video being recorded with a variable frame rate instead of a constant one...the remedy then would probably be to take your video in a program like HandBrake to change the variable to a constant frame rate. And after that, import the corrected video into the Premiere Elements project which has the correct project preset (preferably set manual to assure the correct result).
Please see what you can put together in the way of video details, and we will sort this out.

My audio and video are in sync, but get out of sync as it goes along?

IChat: Poor Audio and Video

Hi everyone, hoping for some insights into improving my connection.
Well, I've read everyting I can find and whilst I can now connect - (DON'T put iChat and Skype in the Login items) - I'm getting pretty unuseable audio and video.
Here's what I've tried and where I'm at:
QT streaming is at 1.5
iChat is on None
Mac Firewall is OFF
I connect via WIFI to a "FreeBox" - a combi router and modem here in France issued by my ISP.
For simplicity I've put my iMac in the DMZ on the router setup page.
The iMac has never run anything before 10.4.8
I do DHCP manually.
There is an AIrport Extreme card inside (AirPort Extreme (0x14E4, 0x87)
Wireless Card Locale: Worldwide
Wireless Card Firmware Version: 4.80.46.0
NO iChat add-ons
Bandwidth... the last speed test says 2,27 Mbit/s down and 136,17 kbit/s up
I Just tried chatting with defcom1 (thanks mate!) and it was really bad - from my end. At his it was apparently OK...???
Would really appreciate some thoughts on this
CHeers, Adam
iMac C2D 2GHZ Mac OS X (10.4.8)

Is this the speed your ISP is providing or was this
something that was recommended here on these forums?
This QT setting is as recommended here in the forums
Do you have a Direct Subscriber Line (DSL) or is it
faster?
Yes, it's a 2Mb DSL line
Obviously you are using the built in iSight camera
and the lighting is OK. Can you try an external
camera, possibly a firewire camcorder?
Haven't access to any other cameras...
Incidentally, I've never had to be in the DMZ but I
don't think this is going to be an A/V quality
issue.
I wanted to establish that this wasn't related to any ports not being open or whatever. Being thorough.
Any other ideas ?
I'm gathering strength to physically move the iMac down to the "FreeBox" (modem/router) and try the same with an Ethernet connection so as to rule out poor WiFi, but I'm not convinced about it.
TIA

I need easy audio and video converting and editing software?

I need easy audio and video converting and editing software that wont cost $400.

I highly recommend you try Video Monkey. It's free, though donations are certainly accepted, and does an excellent job of converting .mov to .wmv. Choose Best (2 Pass) for Encoding Speed and depending upon the size of your original file, uncheck 320 pixels wide to create a larger converted image. I set Quality to "Go Nuts".
Another good commercial program is Video Converter Ultimate for Mac. It works as video converter and editor. The version for 2 Pass conversion is approximately $69. , which is considerably less than the $400+ that Adobe Premiere is asking for its editor. I'd still prefer a freebie though, but there's little choice...

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 don't open together in viewer when double clicked

Hello everyone!
I'm having an annoying problem... it isn't something terribly important, but has decreased my work flow speed. Recently, I've had some trouble opening clips from the timeline in the viewer with the double click.
If I double click the video portion of the clip, even if both the video and two audio tracks are highlighted (and are still linked) only the video portion of the clip will appear (along with "filters" and "motion" tabs) in the viewer, and similarly when double clicking the audio tracks, though both video and audio are highlighted, only the audio tracks and "Filters" tab show up in the viewer. Additionally, once the item is double clicked at the left with the jigsaw pieces that can be used to set video and audio destinations, if I've clicked on an audio portion so only audio shows up in the viewer, only the jigsaw pieces for the two audio tracks (a1, a2) are visible, video track (v1) is no longer present, and vice versa.
I'd appreciate any advice that you all have! It's really driving me batty, in addition to not knowing what I did to make it that way, I can't figure out how to change it back!
Heather

Thanks for the advice.
The clips already appeared to be linked, and the selection "link" was checked, however when I unlinked and then relinked I found that the audio and video would open up at the same time in the viewer... problem apparently solved! However, the clips I had been working with I had to nudge audio and video a few frames apart (out of sync) to get the audio and video to line up. (gives the little red box with a +or- number in it on the clip).
When I unlinked and then relinked, the clip lost those red boxes and went back to being synced (as far as FCP is concerned) with the audio and video unaligned.
So, the problem appears to be coming from when I move the audio and video of a clip out of sync... why is this? Is this something I'm just going to have to deal with?
Thanks

Premiere Pro CC: audio and video is out of sync after export

Hi folks! I downloaded trial version of Adobe Premiere Pro CC. Captured gameplay with bandicam in Motion Jpeg Format (as advised) 30 fps and made a 40 minutes lenght clip. But there is an issue: in my project audio is synchronized with video, but when i export - it's lost (and i think to further we watch video, the bigger is the synch gape between audio and video, in increases gradually). I tried various formats, tried to use option "delete rendered files" prior to export, tried "match source" option, tried to choose various drives for exporting - nothing helps.
Help, how to solve this problem?

Handbrake is a free-download program that takes variable-frame-rate footage and converts it to constant frame-rate. VFR to CFR, if you will.
Going back to your reply to my first post, you noted there had been some kind of "hardlimit" to 30fps that you hadn't chosen. I'm guessing that would have made this track CFR, and what you've got instead is VFR. So you might try recording another bit after selecting that setting to hardlimit the frame-rate, and see if it works better through PrPro to export.
Next ... so, you've got a 30fps probably VFR video track, and it appears a WAV file is your audio ... was that produced by the Bandicam program while it was recording your program? Or is it from another source and you pasted it into your sequence?
