Sync footage with alpha to audio

Here is a situation.
You have a gun muzzle flash clip (or any other pre-keyed footage) and you want to sync it with an audio file such as a gunshot sound.
Since this clip would, by nessessity, be above the primary storyline, Is there any way to link this clip to the SFX so you can move one and not lose sync without losing the alpha channel when creating a compound clip.
P.s. When all this emthesis on linking and making connections, wouldn't it be smart to allow clips to link to each other rather then always linking to the primary storyline. What if i want to move a whole bounch of titles and audio over another clip? What if you want a clip on the secondary story to link to a song cue?

Hi Shane,
Thanks for your help.
Yes, recorded on the tape the vision is about 2 sec behind the audio and also EE through the VT machine if just playing the timeline [which is in sync on the computer].
I am not supplying a reference to the deck. As I mentioned I have used exactly this set up with the same machine and FCP set up without these problems working in PAL about 3 or 4 weeks ago. I also made a DVD of one of the edits and that is in sync. I am thinking it's either something in the Kona 3 - but the problem should be apparent when monitoring it - or in the VT machine. The reference was something I had thought about but I don't know enough about that side of things....

How can I export m2ts footage with 5.1 audio in PP CS5.5?

Dear All!
I have a 90 minutes project which made from 4 sequence. Sequence settings are the followings : AVCHD 1080p 25fps square pixels , 5.1 channel master audio.
I made the sequences from avchd file-s, which recorded with Sony HDR-CX700V with AVCHD 1080p 25fps and Dolby digital 5.1 sound.
Right now I finished the project with lots of effects and imported After effects compositions, and I cannot find any setting to create 5.1 sound.
I have Mainconcept codec suite, but this offer m2ts 1440*1080i settings only.( And I cannot configure the mainconcept codec settings.)
Do you have any idea how can I export the project without any degradation, and with 5.1 audio? The original footages recorded with this properties : H264/AVC - top field first - 22.000 Mbit/sec.
And I use in the project some 720p H264/AVC - progressive - 8.001 Mbit/sec videos.
Please help! Thanks a lot.

You have to consider a couple of things. Mixing 1080 and 720 material is best done in a 720 sequence, because uprezzing will seriously deteriorate quality, unless you accept black borders. That also means exporting a 720 format as maximum, unless again you accept serious quality loss. Whatever the resolution you choose, exporting AVCHD material to anything else than uncompressed, Lagarith or UT will entail a generation loss and thus quality loss. The best export settings are dependent on your delivery medium. DVD, BD or web.
Since you are working in a 1080 sequence, the quality loss of uprezzed 720 material is not a big issue, apparently, so what is the relevancy of 'the same quality' on export when you have already compromised quality?

Trouble Syncing P2 24p footage with 29.97 audio

Hi All,
I'm having problems syncing Panasonic P2 format footage shot at 24p from an HPX-500, and externally recorded sound. I'm using PPro CS5.5 on Win7. I believe this is because the P2 format is actually 29.97fps with some pull-down (Remove Pull-Down setting checked for the clips) and the audio was recorded with a timecode of 23.976.
So when I use the Synchronize feature it gets the clips close, but the audio lags just so slightly, less than a frame. I can switch to audio time units and manually sync, but I have a completed short film with a ton of clips that I have to do this for and I think it would take the next ten years to manually sync ;-)
If there are any solutions to this, I would be greatful for any suggestions on how to handle this. The specs of the video and audio clips are below.

Already given. While camera makes have no problem creating hardware that records audio at a consistent rate, audio device makers either can't or won't do the same.
Hey Jim, sorry - I should have clarified that statement a bit more. The slight differences can be understood by your comment for sure, unfortunately . But the timecode should not be mismatched at all - there seems to be a bad calculation in PPro somewhere. Other applications can read and match the timecodes without any problems (see below).
I found some further info - I had my friend import the footage and audio at his studio with FCP and Avid and they both matched perfectly (he's also going to try Smoke). I also downloaded the trial of Avid Media Composer 6 and the clips matched up perfectly also.
As a test, on my system, I batch "converted" all my audio files using Audition - just saving them with all the same parameters as the originals. Then I imported back into Premiere and guess what? They matched much, much more closely. Still faster by 9951 samples after 00:01:47:00 - so I don't know how noticable 1/48th of a second will be, and I suppose I can find some nice edit points to adjust at. But also back to your suggestion on adjusting the speed of the audio, I may be able minimize that too.
Thanks for your help.

Syncing footage with music track issue in Premiere Pro CC

My experience with Premiere Pro is still limited to basic editing. Recently I've been asked to help out a friend to edit a music video. I've done this before in Final Cot Pro X but decided to switch due to the integration of Adobe CC.
The issue I am facing is that all footage that has been shot is delivered to me at 23.976 fps but with the audio playing faster. The audio track after importing is being played back at 29.97 fps and plays at normal speed.
The solution I have found so far is to slow down each clip to 80% so it matches the original audio track. This is not ideal I found out while editing, so it would be better to have each clip rendered to its original state of 29.97 fps.
After some more research I discovered that it is possible to re-render each clip to its original speed in After Effects, and even apply frame blending. Then import all back in Premiere Pro.
My question is if the road I am following here is the correct one.
Thank you!

by reducing the speed in the timeline, i think it does the same thing as forcing interpret footage. the difference is by changing it in the bin before starting, you can change all clips at once. just make sure to set the sequence fps to the final output fps, not matching the changed fps of clips. you can also right click the footage on the timeline and choose frame blend, but i think it ends up doing the same thing as the export option you are using. the difference on the timeline is you can see the frame blend while editing. AE is extremely slow and might not look any better, so where u are on deadline, forget about it. so in premiere i think frame blend on vs off is your only real option to change the behavior of the slow-mo.
the slow mo trick is nice for music videos, but yeah, for best results the camera needs to be sped up with the song on set. then in post both are slowed back down, replacing the song/audio with the original song at normal speed. 23.976 or 29.97 are both acceptable in NTSC usa land. 23.976 has gotten alot of attention as the "film look" since it has more motion blur, while 29.97 has a cleaner video look. below are some numbers i found somewhere and kept. so if the final render fps is known, can choose the correct shooting fps for on set with matching sped up or slowed down music. the italic values would be used to end up with sped up footage, while the Bold values would be used for slo-motion effect. i haven't used these but the numbers look right. he could have shot at 29.97(30) fps and slowed it down to 23.976 in post to get the 80% slow-mo.
For an NTSC/US, using a 24p timebase, for the following frame rates, adjust the song speed to:
12 fps: make song last 1.956x longer by stretching it to 51.1% speed
18 fps: make song last 1.333x longer by stretching it to 75.0% speed
20 fps: make song last 1.226x longer by stretching it to 81.6% speed
22 fps: make song last 1.067x longer by stretching it to 93.7% speed
26 fps: make song last 0.907x as long as normal; play it at 110.25% speed
30 fps: make song last 0.800x as long as normal; play it at 125% speed
32 fps: make song last 0.747x as long as normal; play it at 133.87% speed
36 fps: make song last 0.672x as long as normal; play it at 148.81% speed
48 fps: make song last 0.498x as long as normal; play it at 200.80% speed
60 fps: make song last 0.400x as long as normal; play it at 250.00% speed
For an NTSC/US, using a 30p timebase, for the following frame rates, adjust the song speed to:
12 fps: make song last 2.445x longer by stretching it to 40.91% speed
18 fps: make song last 1.667x longer by stretching it to 60.00% speed
20 fps: make song last 1.533x longer by stretching it to 65.23% speed
22 fps: make song last 1.333x longer by stretching it to 75.01% speed
24 fps: make song last 1.250x as long as normal; play it at 80.00% speed
26 fps: make song last 1.134x as long as normal; play it at 88.22% speed
32 fps: make song last 0.933x as long as normal; play it at 107.14% speed
36 fps: make song last 0.840x as long as normal; play it at 119.05% speed
48 fps: make song last 0.622x as long as normal; play it at 160.73% speed
60 fps: make song last 0.500x as long as normal; play it at 200.00% speed

Audio sync issues with variable frame rates as well as .ts files

I'm using Premiere Pro CS6 and CC, in Windows 8.
I bought an AverMedia Live Gamer HD card to capture 1080p footage with, and the the videos it produces work perfectly during playback. No sync issues whatsoever. I'm saving them as MP4 at 30fps.
The problem is when I import them into Premiere Pro, the audio loses sync at certain points. After a bit of digging, I've discovered that the videos have a variable frame rate, which Premiere Pro does not support. I don't know why, considering competing products that are significantly cheaper can handle them with a problem, but oh well. The capture card can also save videos in .TS format, which produces a constant frame rate, however when I import them into Premire Pro the sync is immediately off by a second or more. I assume this is for an entirely different reason. Again, they play back normally without a problem. Upon emailing AverMedia, I was told this was Adobe's problem and there was nothing they could do about it.
What I'm wondering is if there is any sort of realistic solution to this as of now. Is there any way that Premiere can work properly with files that have a variable frame rate? If not, is this being worked on?
Or maybe there's a way to get the .TS files back in sync, that way the variable frame rate issue doesn't matter anyway.
Converting the files is not a long term solution. I'm working with hours and hours of HD video, and it would take way too much time to do this.
Manually resyncing the audio is also not a solution. Again, this would just be way too much wasted time with each project.
The only solution I see as of now is to switch to Sony Vegas until this problem is resolved in Premiere, if it ever is. I'm really hoping there is some other way, so if anyone has an idea as to how to fix this, I'd really appreciate it.
Thank you.
tl/dr:
Is there any way to get around Premiere Pro not working with variable framerates? My .TS files are also out of sync, is there any way to fix that? Without converting or manually resyncing.

>If not, is this being worked on?
Discussed many times before... never a "yes" answer to your question... tell Adobe what YOU want at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
If enough people make a request, Adobe MAY add the feature (I don't work for Adobe, so no guarantee of anything)

Canon cameras have audio sync issue with FCP?

My mini dv deck died on me so,
I am using a small palm size Canon mini dv firewire camera to transfer about 50 tapes.
I am having a weird audio sync issue.
Sometimes the capture footage plays down in sync - I pause>scroll>play - and it's suddenly out of sync. This keeps happening. Sometimes it plays in sync. Other times it does not.
Because it's hit and miss- I'm not sure I can even re-sync.
I imagine it could be the media drive (internal)- but I have other video files on this drive that play fine.
I don't often use firewire capture.
Is audio sync a common firewire issue?
Will the quality suffer if I capture through composite/analog audio outputs?
I can patch it through my
decklink card.

Audio sync is an issue with Firewire, just not all the time. Usually it is fine, but a lot of Avid people don't like Firewire for this reason.
Most often it is a 5 frame sync issue. Slip your audio 5 frames forward and see if that solves the problem.
As well, take a look in your Browser after you capture a clip and see if the Aud Rate is either 48,000.5 Hz or 47,999 Hz. I have seen the clips come in as both of these. Once you slip the footage, export the audio only, then reimport and attach the audio to the clip in the timeline. Should take care of it.
Post back if these don't work.

Sync audio with multi camera audio mistaken

Hello everyone, i really need big help. It's not an adobe issue. propably it's my fault.
So, here's the deal. I edit a music concert. I've been given the original audio footage and i used 3 cameras.
Even though with synchronize option i synchronized each one with the original audio while i'm editing it seems like after a while it's unsynchronized. Any idea please? i've spent lot of hours doing it separately but it always losing synchronization.
Thank you all, in advance.
I've noticed that while the audio is in 44100hz camera settings are in 48000hz. i tried to convert the audio but finally it didn't worked.

It seems fairly normal for separately recorded audio to drift out of sync on longer shots. I'm not entirely clear why camera makers can get all their cameras to sync perfectly with each other, even across manufacturers, yet audio recorders have such a hard time with this. But...they do.
The solution is to find out by trial and error what percentage your device is off, and then apply that change to the audio clip. I had a recorder that needed to be speed adjusted to 100.04% in PP for the audio to remain in sync, so I applied that to every audio clip from that recorder.

Playback pauses and audio sync issues with live video stream

I'm seeing playback pauses about every three seconds and audio sync issues with our live demo stream when using the OSMF/Strobe player. It happens on both our 2Mbps 720p stream and our 480p 750Kbps stream so it does not seem to be related to higher resolution/bandwidth streams. It also happens if I point directly to a stream asset or if I point to a .f4v with both streams listed for dynamic so it does not seem to be related to dynamic streaming specifically.
The same live streams play back very well without pauses or audio sync issues in the Akamai's dynamic player and even slightly better with JW 5.2.
I have viewed the OSMF/Strobe playback on three different laptops of various age (3 months to 2 years) and two are Windows and one is Linux. I have also tried the various buffering options on the Flash Media Player Setup and Strobe setup and it has not made a noticeable difference.
To see the stream with the Akamai player, go to: http://live.kulabyte.com
To see the stream with the OSMF/Strobe player, go to: http://live.kulabyte.com/osmf
I do not have JW set up for public viewing yet, but the two above show the distinct difference.
We are really hoping to start pointing our customers towards the OSMF player because of the support provided by the community and Adobe, but we have to get the quality of the playback to be acceptable first.
If someone has ideas on debugging I can PM the actual video assets to you.
Thanks,
Tim

Hi Tim,
You need to add this setting:
dynamicStreamBufferTime=8
The actual value can be higher or lower. The best practice is to use a value that is twice the keyframe distance. Anyway, try different values and see which performs the best for your content.
I know that the setup page does not contain this option and it is not documented in the UserGuide. We simply missed it. Sorry.
Also note that the dynamic buffering algorithms are not being used for dynamic streaming content. I tried to explain this here:
https://sourceforge.net/adobe/smp/wiki/Dynamic%20Buffering/
Looking forward to your confirmation that this solved your issue.

Recently I have not been able to sync itunes radio with my wireless audio player. What happened?

I cannot get itunes radio to sync with my wireless audio system. It was working until recently and now only downloaded music will play. Is this a function of the system or did itunes do something?

Hi,
Here is a suggestion from Carolyn Samit that worked for this problem with iPads - see if following her instructions clears up the problem with your iPhone:
Launch iTunes with your iPhone connected to your Mac. Make sure the iPad is listed under Devices on the left side of the iTunes window.
From your iTunes menu bar click iTunes / Preferences then select the Devices tab.
If there is more then one backup available, delete all but one.
Restart your iPhone. Press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the Sleep/Wake until the Apple logo appears.
Restart your Mac.
Try to sync now.
Hope this works for you!
Cheers,

i cannot sync music with my ipod touch 4th gen.when i click on sync,nothing happens and the audio capacity bar on itunes disappears.i'm using microsoft windows 8 consumer preview

You can only sync with one computer. I would backup to one computer and then restore from backup.
iOS: Back up and restore your iOS device with iCloud or iTunes

RED footage with audio won´t import to timeline anymore?!

Hello,
I cannon import any RED footage to the timeline anymore. I can import it with media browser, view it in viewer and make a new comp with it but there is no way to get a clip from the viewer to the timeline. It works fine with RED footage that has no audio.
I am running 8.2 and this worked fine a week ago...
Any info?
Thanks

So it gets more confusing ...
I cleared all the .xmp files from a folder, and drag and dropped straight from explorer to the timeline, it all imported !
So i start do this for a few different folders, seems to be working...
I then say , well hey ill go back to media browser and try to reimport and organise my file structure the way i like.. all of the sudden it reverts back to audio only, even from win explorer, then i grab 4 clips at once ... it imports them ?
So, i go back to media my project window, grab 3 files, and it now drops them on the timeline.
I won't play like I'm understanding the logic here, one would think spanning clips or somthing but it seems much more random
Though, if in the future anyone has this problem, try draggin more than 1 clip at a time in and see if that gets you going.
ADOBE : Can you please shed some light on this, although i have figured a strange work around, this means i cannot use the source window like a usual workflow and i must actually import everything to the timeline then cut and scrap the rest.

Audio Sync Problems With Share YouTube -- OSX not iOS

I've replicated this several times. It's maddening and bizarre. *Share YouTube*
Exporting a FCPX video using the "SHARE" menu and choosing YouTube causes the resulting upload to be out of sync when viewed in Safari or other browsers on iOS
Viewing the same video on the iPad with the built in YouTube app, the video plays in sync
Viewing the same video on AppleTV 2 (with the 5.1 update), the video plays in sync.
If I export using Export Media menu item under the SHARE menu, and then from QuickTime Player choose Export For Web (under the File menu) and manually upload, the video is in sync.
Note, that using
Feel free to try on this short simple and silly video http://www.youtube.com/watch?v=cGTQNMJdPRQ&list=UUiDxioBFJCPC-8OUFifsx8A&index=2 &feature=plcp
Anyone else experience this. Is this a bug or a feature? Rather not go through three steps to upload a simple YouTube video.

We've got the same problem and yep, it's infuriating that are so few posts about it.
It doesn't happen with every video, but the vast majority of files that we've tried to either export directly to YouTube from QTX or export locally and then manually upload to YouTube end up with shockingly bad audio sync (and also some colour issues, but that's another story).
As a small video production company we were chuffed to bits with the improved export speed in QTX and quick to make use of it. But when we realised there was a problem, we had to revert back to using QT7's painfully slow export.
We've run experiments on a brand new iMac and MacBook Pro running the most up-to-date version of OS X and still no joy. Always the same audio sync problems with the same video files.
In the meantime however, we've found that the settings advised on this YouTube help page have given us the best (albeit slow) results at both 25fps and 30fps when exporting from QT7:

Replacing footage with an alpha channel

greetings gurus... I'm working in FCP 5.1 with DVCPRO HD footage 720p @23.98fps. I have an edited sequence of green screen footage that I am happy with. I then keyed out the green from the original source footage and exported that footage with an alpha channel (the background keyed out in AE7). My goal is to open my FCP project and replace the original source footage with the new keyed out footage so that my edit remains in tact but now with a keyed out background. I'm using the reconnect media function in FCP and of course the footage is replaced, but without the alpha channel.
When I import the keyed out footage directly the alpha channel is present; it just isn't present via the reconnect media method.
Any suggestions on how to pull this off?

it may be that for whatever reason FCP is not interpreting the alpha channel correctly when you use the reconnect option. for example, the reconnect option may assume that clip properties are unchanged. this may be esspecially true within the timeline, where instance properties are preserved.
you may be able to manually overcome this by adjusting the alpha channel information in the clip properties window
select one of the reconnected clips (one with the alpha channel from AE) and press cmd-9. see what setting is reported for the alpha channel. if it says None, try changing it to Straight.

How to reconnect footage on timeline with deleated track: audio or visual?

if i remove an audio track, and then open the source I have difficulty finding a way to reattach audio into the footage with out resetting the in and out points in bin source file, I have multiple cuts from camera rolling and when opening the source file- can not seem to use the in out points for the selected edit the thing I am trying to bring back with audio and with out having to reset the points again and redoing the edit (long sentence right?)? tried searching for an answer, landed here...J

I'm not quite sure what you mean but to re-insert either video or audio for a clip in the timeline is easy.
1. Park playhead over desired clip in the timeline
2. make sure the track selection box is highlighted.
3. Press "X" to select clip.
4. Press "F" for match frame.
At this point your clip should appear in the source monitor with in and out already defined.

Severe audio sync issues with DVR and RAI(Italian) channel.

Having severe audio sync issues with the Motorola QIP6416-2 while
watching RAI(Italian) channel. The audio is about 2 seconds behind
the video. This is the only channel it seems to happen with.
I just switched from Cablevision about a week ago and never had a
sync issue with their DVR with the same RAI channel or any channel.
I've tried changing hdmi cables with no success and I also went to
component video cables but the problem remains. Resetting the
box helps but within 15 minutes the sync issues return. Also,
a channel change and back helps briefly,
The only new piece of equipment in the mix is the Motorola DVR,
nothing else has changed. The DVR is connected directly to my
tv.
Any help is greatly appreciated.
Mike

Being a foreign channel, there may be something screwy with the framerate (PAL conversion?). I don't personally subscribe to any foreign languages channels and I doubt too many on this forum do either, so you may have trouble finding someone to replicate the problem on their end here.
