Audio and video question.

I have a standard audio button on page one of my folio but when i swipe down to a page that has a video it kills the audio.
It only kills the audio exactly when the video starts.
Thoughts?

Pretty much how it works. One or the other and one at a time.

Combined Audio and Video bitrate question

When combining audio and video, how does the bitrate of the audio affect the calculation of the total bitrate? If I set my video compression bitrate at 5.5/7.5, how should those numbers be altered if I have, say, two Dolby Digital 2.0 streams at 192kbs each and a 5.1 surround stream at 448kbs?

From the DVD Studio Pro User Manual (p. 43):
Beware of Setting Your Bit Rate Too High
You will find that with some DVD projects, the content easily fits on the disc, and you may be tempted to use the highest video bit rate available. While higher bit rates produce better quality, you must take into account other factors before deciding to use the maximum allowable value.
The maximum video bit rate allowed on SD-based DVDs is 9.8 Mbps, but rarely is that practical to use since DVD players support combined video, audio, and subtitle bit rates of up to 10.08 Mbps. For HD-based DVDs, the maximum video bit rate is 29.4 Mbps for HD assets and 15.0 Mbps for any SD assets used in an HD project, with an overall maximum bit rate of 30.24 Mbps.
In practice, you should be conservative when determining how high of a bit rate to allow for. Trying to squeeze out the highest possible bit rate for your project can lead to player compatibility and disc space issues. A general recommendation is to not exceed 9.2 Mbps for the combined video and audio bit rates when authoring SD projects, or 29 Mbps when authoring HD projects.
Important: If you are building your project and DVD Studio Pro detects that the bit rate of the multiplexed stream is too high, the build stops and an error message appears.
Using PCM or AC-3 Audio
A single PCM audio stream using typical settings (as produced with the embedded AIFF encoder) requires 1.536 Mbps, which leaves an absolute maximum bit rate for the video in an SD project of around 8.54 Mbps. If there are two PCM audio streams, 3.07 Mbps must be allowed for the audio, leaving just 7.01 Mbps for the video.
Note: Even though you can only play one audio stream at a time, the bit rates of all audio streams must be added together when determining the overall bit rate for a track. Similarly, all subtitle streams must be added together and added to the overall bit rate.
Using AC-3 audio in place of the PCM audio leaves far more room for the video bit rate. Stereo AC-3 audio using typical settings requires only about 224 kbps—using two stereo AC-3 streams in place of the PCM audio leaves about 9.6 Mbps for the video.
See “Calculate the audio allowances” on page 636 for more information about allowances for other audio formats.
Hope this helps
Good luck!

How to get audio and video in one file

hi...I am "premiere beginner user" and I have a simple question , I think..:)...Every time when I am trying to export media out from my premiere (using media encoder) I get video file and some audio files, but what I need is only ONE file, that contains both (audio and video)..for example , I have edited film in hd quality and I want it to export, I choose h.264 format(make some settings,pal,audio quality...) and when it´s "all done", only "result" I get is one video file and two audio files and they are not together :).....so please help mme anyone..ok and as you can see I am not from english speaking country, so sorry for my english...thanks for help....

There is no indication that something is out-of-sync or the ability to move/slip into sync like in FCE/FCP.
To the best of my knowledge, using match frame and overwriting the video with video+audio (or attaching it as a connected clip if you don't want to overwrite the video, which might have effects applied) is the best way to do this.
You can use the blade tool first in the timeline to get just the section you want to get back into sync. Make cuts so that you have a single clip that needs the audio resynced, select it, and use shift-F to select the original synced clip in the Event Browser. Make sure your play head is at the beginning of this video clip in the timeline. Press option-2, then 'q', and now you have the audio back in your timeline, synced with the video. Delete the old, no-longer-synced audio and you should be set.

Why can't Adobe Premiere Pro CC 2014 Time remap Audio and Video together?

In case you didn't notice, my question is WHY. I don't know why Premiere Pro can't do this. From what I understand at the moment, the only way to time-remap audio in any way shape or form using Adobe software is through Adobe After Effects, which my computer has absolutely no chance of running ever. I know how to do regular stretching of audio in both Audition and Premiere Pro, but apparently I can't time-remap audio using either of these programs.
So why can't Adobe Premiere Pro time remap audio along with the video? What's the reason that it can't? It's a massive disappointment and would be very impressive to see accomplished in the future. If it's possible to time remap audio and video together in After Effects, that's great and all, except for the fact that I can't use that program. Why can't it be done in Premiere Pro and will it ever be possible in Premiere Pro?
Also, will time remapping audio become possible in Audition someday?

That sounds like a great idea. File a Feature Request:

Audio and video out of sync after converting to mp4

I've tried 3 converters (ImToo, Xilisoft, and Videora) and for 2 videos I really want on my ipod, the audio and video are offset. Infact, on Xilisoft, one wouldn't even convert (to anything ------as both are WMV and I thought that might be a problem--but I found I had another WMV that had the audio matching the video fine). For the other vid., I tried on Xilisoft making it an AVI first, but that AVI also had messed up audio/video
This is a really broad question, but what can I do and what programs can I try to get the videos to convert properly??
(I've tried uploading the wmvs to itunes to have itunes "convery for ipod", but they wouldn't even upload to itunes)
30gb video ipod Windows XP

I have also had similar problems. Unfortunatly i have yet to discover a program that works perfectly. Just keep searching is really all i have to say. However if you do find it, could u please post it

Audio and Video out of sync in shared iMovie file

Hey Guys -
Quick question, I've created a new trailer in iMovie, all works fine but the audio and video is out of sync in the shared file. How to fix it?
Thank you
MondCharlie

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.
Grr,

How can I combine the audio and video files from youtube downloads when they don't automatically combine?

I'm using YouTube Video and Audio Downloader. Sometimes the audio and video files combine automatically, sometimes they don't - remaining as separate " DASH - .m4a and DASH - .mp4 ". It used to be that when this would happen I could open up a "ffmpeg" window which would allow me to "manually" convert them to a combined .mp4 file. It was a "drag and drop" type of interface. For some reason I can no longer access that ffmpeg combining function. I tried clicking on ffmpeg.exe. I tried re-downloading ffmpeg several times, both from the Downloader options tab and from the ffmpeg website.
Thanks for your help.

Sounds like a question for the developer of the video download add-ons that you have installed.

Why does say"To play the selected item, you must install a later version of the Adobe Flash Player. To download the Adobe Flash Player, go to the Adobe website." when I have the latest Version of it and it's just Black screen with no audio and Video?

When exporting separate audio and video streams, the audio drifts out of sync

So this is my first slightly larger project in Final Cut Pro X.
When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

Audio and video compression preferences for export to DVDSP

Hi,
I have a few questions here. The first is regarding the internal use of compressor by DVD Studio Pro. It is my understanding from (limited experience with) past projects that quicktime movie files are automatically compressed to an mpeg2 format when imported into DVDSP. To what extent do I have control over the level of compression, and are the default mpegs that were made optimal quality? Where can I check this?
My second question is regarding compression of audio files. Whereas my video files were automatically compressed, I am not so sure about the audio. I was forced to compress the audio down to Dolby2 separately using the external compressor program, in order not to exceed the bitrate on my last project. Was this just a question of one or the other (video/audio) needing further compression than the default amount, or is there more to this issue?
I live and work with video in Europe, where I have recently been told that optimal audio is mp3? 4? rather than Dolby 5.1? Is this correct, and how much more space does dolby 5.1 take than dolby2? How significant an issue is this when making dvd's for musicians?
Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe?? or explain how I might go about finding this out for myself?
Thanks a lot, and I look forward to reading your comments.

Settings for DVDSP's internal encoder can be adjusted in DVDSP preferences. Press Command-, - that's the Apply and the comma keys - to bring those up, then select the Encoder tab. In your case, make sure you adjust the settings for SD DVD (and not HD-DVD). You will also be able to specify whether to encode in the background (basically, as soon as you import your file) or encode on build, at the bottom of that tab.

I can't confess to have read any of your previous threads, but if you exceeded bit rate, that is a common reason to need to use Dolby compression for your audio. (unless you can afford to recompress your video files)
That is, if you video files use a high bit rate (say over 6 Mbps average), then it's usually necessity to use Dolby compression to make sure that all your footage fits on a single disc. (this is a simplification, of course, but I think you get the idea)
Or was there more to this question that I'm missing?
I live and work with video in Europe, where I have recently been told that optimal audio is mp3? 4? rather than Dolby 5.1? Is this correct, and how much more space does dolby 5.1 take than dolby2? How significant an issue is this when making dvd's for musicians?
Someone was mistaken when they told you that DVDs accept - let alone are optimized for - mp3 or mp4 files. That's flat out wrong.
As for the difference between Dolby 5.1 vs 2.0, that depends on your encoding rates. Typically, most folks encoder Dolby 2.0 at 192 kbps, with some choosing to up the bit rate to 224 kbps. Beyond 224 kbps, you're not actually improving audio quality for a 2.0 mix, you're just bloating your file size. When it comes to 5.1 audio, it's typical to encode your audio at 384 or 448 kbps.
When it comes to compressed audio vs uncompressed audio, it does matter when you're making DVDs for musicians. But that means that you'll probably need to lower the bit rate on your video files.
Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe??
If you want to keep you audio as AIFF files, set your encode to 2 Pass VBR Best, with an Average bit rate of 5.0 Mbps and a Max bit rate of 7.0 Mbps. If you need things to happen a bit faster, use One Pass (not One Pass VBR) and use 5.5 Mbps as your bit rate.
If you want to have a firm grasp over how all these numbers work, there is a section at the back of DVDSP manual, that explains how to calculate bit rates (what we call bit budgeting in the business). Give that a quick once-over if you can.

Audio and Video Performance Tweaking

Hey guys I'm back with more questions. I'm trying to improve the overall quality of my video conference experience.   My target market is the elderly and their families, so not necessarly people who are used to computers and tweaking things so we want to make it as good as we can right out of the box.
Video
1.) All of my decoded video has clearly visible blocks. I've attached a sample screen shot to show what I mean. Is there a deblocking filter option I'm missing somewhere?
2.) The encoder in flash player 10.x is still H.263 based right? I'm not missing a secret option to use the H.264 encoder am I?
Audio
1.) I've set my audio codec to speex in my audio publisher, and it looks like it defaults to a quality setting of 10 (<rtc:AudioPublisher id="audioPub" codec="{SoundCodec.SPEEX}"/>). Am I missing any tweaks to improve the audio quality?
Audio questions where I assume the answer is no but I ask anyway
2.) Does the LCCS code or flash player prioritize audio packets over video packets or are they just sent when they're available. I'd like to sacrafice video for audio if it's possible.
3.) Is there a way to better syncronize the video and audio streams. Right now there's a lot of lag between what is said and how the lips move (this is even with peer to peer on the same private network).   I get the idea that there isn't but I thought I'd ask.
4.) Is there anything I can monitor to give me an idea of the current connection performance?   In otherwords can I monitor something and then make my own decicions to reduce the video quality or audio quality based on avaiable bandwidth between the two connected peers?
5.) You secretely have echo cancellation built in but were waiting till now to tell me right? Just kidding.
Thanks as usual
-Eric

Hironmay,
       Thank you for getting back to me, I know I asked a lot in one post there.   It would be nice to have a way for audio packets to be prioritized over video since they need to get there but you can live with dropped video frames.   I'd love to see a way to sync the audio and video up as well. I was just reading about some research where they showed if you can watch someones mouth move while you hear them talk it's equivelant to a 20dB volume increase (referrning to how well the person can understand you.)   I have elderly users so something like that is very important to me.
I agree with you that when I changed the captureAndHeightFactor that the blocks got smaller, but did not go away. I was hoping there was a way to smooth out the edges of the blocks so the boundries don't look so harsh.   I had been looking at flash.media.video in the flex 3.4 language reference and it talks about deblocking. I copied the relevent text from the documentaiton at the end of this message. I was wondering if there was something there I could use.   I'll play around with it some more.
Believe me I've been very vocal about the need for echo cancellation on the Flash Forums
Thanks for the help,
Eric
relevent text from flash.media.video
deblocking
property
deblocking:intIndicates the type of filter applied to decoded video as part of post-processing.      The default value is 0, which lets the video compressor apply a deblocking filter as needed.
Compression of video can result in undesired artifacts. You can use the       deblocking property to set filters that reduce blocking and,      for video compressed using the On2 codec, ringing.
Blocking refers to visible imperfections between the boundaries      of the blocks that compose each video frame. Ringing refers to distorted      edges around elements within a video image.
Two deblocking filters are available: one in the Sorenson codec and one in the On2 VP6 codec.      In addition, a deringing filter is available when you use the On2 VP6 codec.       To set a filter, use one of the following values:
0—Lets the video compressor apply the deblocking filter as needed.
1—Does not use a deblocking filter.
2—Uses the Sorenson deblocking filter.
3—For On2 video only, uses the On2 deblocking filter but no deringing filter.
4—For On2 video only, uses the On2 deblocking and deringing filter.
5—For On2 video only, uses the On2 deblocking and a higher-performance      On2 deringing filter.
If a value greater than 2 is selected for video when you are using      the Sorenson codec, the Sorenson decoder defaults to 2.
Using a deblocking filter has an effect on overall playback performance, and it is usually      not necessary for high-bandwidth video. If a user's system is not powerful enough,       the user may experience difficulties playing back video with a deblocking filter enabled.

Audio and video offset in imported media

When I import a media from the camera who took the film, there is an offset of 2 seconds between audio and video track.
I have to dissociate the two tracks and create manually an offset in order that the sound match the images.
How to prevent that and get the 2 tracks audio and video in correct synchro, just like when viewing the film directly from the camera ?
Thanks,
Pierre

We are very glad that you have found the answer to your Premiere Elements question which appears to relate your Samsung Galazy camera/Premiere Elements 11 Mac/"out of sync" audio/.
But, if you have the time, could you explain why you "...created the project using a PAL setting at 25 frames...." (you did not say what PAL setting beyond the frame rate)> I ask you this question since you stated earlier in this thread that your source media and project setting were:
I use Premiere Elements 11 on Mac OSX 10.8
The video is done with a Samsung Galaxy Camera.
The format is MP4 1920x1080 30frames H.264, AAC
The settings of the project are in accordance with the file : image 1920x1080, 29,97 frames
The answer to the above would help to explain how you came to your success when you wrote
I've found the reason of the offset : I had created the project using a PAL setting at 25 frames. I've now created a new project using the NTSC HD Full HD 1080i 30 and that works fine.
Thanks.

Syncing externally recorded audio and video workflow

I'm looking for advice to sync externally recorded dialogue to video, exporting them, and importing them back into fcp7.
I've done this before, but not on this large scale. I have many clips and I did record audio with the camera as well.
I know how to sync everything up, I'm mostly looking for the best way to combine the footage and export it without loss of quality. Also wondering if I can keep the in camera audio AND the externally recorded audio. So, if at the end of the day, I absolutely need to use one or the other, I can choose which one and hide or delete the other.
My questions are...
1. What's the best way for lossless quality re-exporting and importing for this (some fomat that is still editable)?
2. Is there a way to keep multiple channels of audio (from the camera and the h4n) or do I have to choose before exporting?
3. Is there a "batch" way to do this? Does it consist of making multiple sequences?
Thanks for your help!!!
J
I shot it on a PMW EX3 and the audio was recorded on an H4N, if that helps.

1. Why are you re-exporting? No, that's not what you do. You use the MERGE CLIPS command. This will make a NEW clip with the audio and video files merged. Typically you have a slate to sync to, or timecode is jam sync'd so the camera and audio recorder have the same timecode.
2. When you merge the clip, all the audio channels will be present.
3. Sorta. If you get PluralEyes that will automatically sync everything...but will do so by making a sequence with the video and audio. So a sequence of sync'd audio...not a clip. And if you use the sequence as a source, you need to make sure to use the OVERWRITE WITH SEQUENCE CONTENT mapped to the F keys, otherwise FCP will make those nested clips, and nested clips are not a good thing in this case.

Audio and video question.
