MP4/H.264 Audio Skipping

I just upgraded to the new 7.2.2 and I now have an MP4 file that is not playing properly. I drop it in the project and bring it up on the source monitor as well as drop it in a timeline. Playing the footage, it looks fine but the audio is cutting out and skipping. There are no places where its no audio, but rather sounds like frames ar ebbing dropped. It plays audio properly for a few seconds then seems to jump several frames ahead. Like I said, the video does not do this.
The footage came from a Sony Handicam that has AVCHD format ay 60 fps, and I used Prelude to bring it in as MP4/H.264 to 23.975 fps. It worked FINE with the previous version of Premiere and have already produced several things from it without this problem.
I have tried having the footage being re-interpreted at different frame rates and it changes the pitch of the audio, but does not take out the issues with the skipping/jumping ahead to audio frames.
I need a solution to this, Adobe. Really irritated these problems pop up with new versions. They are supposed to fix old problems, not break things that are already working. My project is now on hold, but due tomorrow.
[Please choose only a short description for the thread title.]

Ok, bit of an update. I had assumed the icon I had in my dock would be loading up the NEW version (8.0) or Premiere. It wasn't. So the skipping problem I had was running on the 7.2.2 version. However, I found version 8, loaded it up and it has the very same problem. The audio is jumping frames or something. It is hard to explain. But it is happening with BOTH 7.2.2 and 8 versions. Sounds like the codec was re-written that both versions use and it's totally fouled up.
All my Canon 7D and 5D Mark II footage works fine.
I may try and open Final Cut Pro X and see if that clip gives me the same problem on that platform.

Export multichannel mp4/h.264 with Adobe Premiere Pro CC

Dear community,
we currently test the Adobe Premiere Pro CC trial (German) on a Windows 7 Professional PC.
However, we are not succentful in exporting a multichannel mp4/H.264 clip.
We haven't found an answer on our issue so far, so I hope that this question was not answered several times before in this forum.
If we chosse the H.264 exporter, we cannot select a multichannel audio export (only mono, stereo, 5.1).
In contrary, if we select the Quicktime exporter, we are able to export our sequence with a 4 channel audio master with 4 mono tracks, but we can only export it with a DVCPro Codec in a mov container.
If we try to select a HD H.264 preset we get an error alert stating that the preset contains a not compatible video codec.
What are we doing wrong?
Thanks for every suggestion.
Thanks in advance
André

Thanks for your thoughts, Richard.
Your are right, we currentky use the Adobe Premiere Creative Cloud version.
We managed it to solve at least the error message. It was caused because Quicktime was not installed together with the Adobe Premiere Pro / AME setup on our computer.
After we installed Quicktime 7 manually, we can select a Quicktime/H.264 preset without any problems within the exporter settings.
However, the Quicktime/H.264 export dialog seems to only allow a mono or stereo audio export. No multichannel-audio export.
This possibility is only displayed in Richards case, if we select the Quicktime exporter and an Uncompressed Video or DV preset.
Our question to the Adobe developer guys is the reason behind this limition? Other video authoring prograns can export a mp4 with H.264 Codec with multichannel AAC without any problems.
How can we do this with Adobe Premiere Pro (not necessarily via Quicktime)?

VideoDisplay component to play mp4/h.264 content

Hi,
I want to build a simple video player that plays HD movie
content.
Can the VideoDisplay component in flex builder 3 be used play
mp4/h.264 content?
If so how is it done as I have tried setting VideoDisplay's
source to a local MP4 file and it will not play? I know for sure
that the file is loaded and that it is h.264.
Can anyone please help me?
Regards
Adam
Flexchief

Hey chief,
I think you'll find the answer to this issue lies in your
encoding, not in Flex.
The VideoDisplay component plays FLV files and H.264. Your
video file must adhere to the MPEG4 specs. If you've created an MP4
file using an Adobe product, this should work if you did not stray
too far from the Adobe Media Encoder settings, like trying to
squeeze the file size down too far. Flash player 9.0.115.0 or later
must be used to view H.264 video.
If in doubt, use AME to create a small MP4 clip at default
settings (use something like "web banner 320x240") and see if that
plays. If it plays, start going through all your encoding settings
and see if you set something out of spec--like maybe the audio
settings. Just use straight AAC for the audio, 48kHz, 192 kbps
bitrate. Video, use NTSC (fps shouldn't matter...) progressive,
square pixels, "main" profile, "level" of 3. Change the Bitrate
encoding to CBR (you are probably using VBR for high quality, but
just try it).
Any of these settings may trip Flex up. You just have to
experiment. If this doesn't work, send me some more info on how you
created the video file.

Sharing an iMovie as an MP4 with MP3 audio

I have an iMovie that is complete. I have uploaded a Quicktime movie to Google video. The video plays but no audio. They are telling me that they prefer MP4 with MP3 audio. If I go to share in iMovie, I choose "export" mode. This gives me the MP4 option, but no way to change the audio to mp3. Am I missing something?

iMovie doesn't use (or create) .mp3 (MPEG-1 Layer 3) audio.
From the Google video upload pages:
Technical Requirements:
We accept many popular formats, such as AVI, ASF, QuickTime, Windows Media and MPEG formats. For example, .avi, .asf, .mov, .wmv, .mpg, .mpeg, .mp4, .ra, .ram, and .mod are all acceptable file extensions. Please note that we currently do not accept Flash files. Specific video codecs we accept include H.264, H.263, MPEG 1/2/4 and motion JPEG.
The video must contain recognizable video content (video container files that do not contain video will not be accepted).
The frame rate should be above 12 frames per second.
The bitrate must be above 260 Kbps.
The video must be at least 10 seconds long.
If you have a video in another format, we will do our best to interpret it.
Quality Recommendations:
If possible, we suggest uploading the original source file. However, we recommend the specifications below for maximum quality and reasonable file size:
MPEG4 (mp3 or mp4 audio) at 2 mbps
MPEG2 (mp3 or mp4 audio) at 5 mbps
30 frames per second
640x480 resolution
4:3 frame
de-interlace
MPEG-4 Video and AAC audio codecs in a .mov container should work just fine.

MP4 H.264 video won't play in Flash Player

I am using a Mac Book, OS X 10.8.5; FireFox 32.0.1; Flash Player 16.0.0.305. I am trying to play video (MP4 H.264 format) that works on VLC, Quicktime Player & Real Player but won't play through Flash Player. Why?

I'll take a look at the GPL sources to see how the firmware encodes the video output, I think the mpeg encoder might be built into the firmware's Linux kernel (instead of a stand-alone encoder program), I see references to the IBM mpeg2 headers but I'm not sure. But honestly addressing this possible bug is not the first thing on my todo list, but I do fidn this report interesting enough to merit investigation.
May I ask what you are using for the Samba server (aka windows shares)? Do you use your desktop PC, or perhaps a NAS server?
As an interim thing to try, I advice you install VLC media player to view the files, or to use VLC to examine the media files properties to see what you can findout.
IF you must use Windows media player, then I suggest you look into the combine community codex package.

Video and audio skipping in PowerDVD 8

Hi,
I have an issue when I try to play DVD's in PowerDVD 8. Exactly every 5 seconds the video and audio skip, or jump/become choppy and I cannot watch a movie. I have been researching and trying to figure out what is happening but have no idea. Could it be the X-fi I have installed the latest beta drivers to no avail.
Anybody have this problem or have any ideas on how to fix it's I have updated all drivers/firmware for everything and still can't make it go, sigh.
I have the following specs:
Intel x38BT mobo
X-Fi Fatalitly champ.
4GB DDR3 RAM
9800 GTX
ASUS 8x dvd-rom
E8500 CPU
Win Vista 32-bit
Thanks

Try this utility:

and post results.
Gigabyte Boards at least with x48 chipset have an audio latency bug that is only fixed via a beta bios update. I have no idea if this also might affect your board...

FLV supporting but .mp4 (H.264 encoded) video not supporting in mobile browser?

Hi
I want to know one things, is there any other settings required to publish the swf file for playing mp4 file in mobile browser also. I am able to play ".FLV" in mobile browser but not able to play ".MP4" (H.264 encoded) in my mobile browser.

Please look at the following url which is not opening in Mobile browser but can open in computer broswer.
http://karzzzz.bigflix.com/m/
I want the above url to be play in both computer and mobile browser also as it calling .mp4 file from Flash Media Server.
Thanks
Sunil Kumar Sah

Are you using Flash Lite Plug-in or Flash Player Plug-in on your mobile browser. I have a feeling that you are using Flash Lite Plug-in and flash lite plug-in (latest is 4.0 i suppose) does not support H264 encoded files.
MP4 file which you are playing from youtube might not be H264 encoded , it might be On2 VP6 which is supported in MP4 container.

Programs for converting avi to mp4/h.264

As the title says. I'm looking for a really good program for this, i want really good video quality, and it doesn't matter if the program is for free or if u need to buy it. I'm a windows user.

As I understand it, AVI is a somewhat lower quality to begin with. That said, you can use Quicktime Pro to convert to your specified format. Quicktime Player for Windows is free; the QT Pro upgrade will be required to output to mp4/h.264.
You can get Quicktime via http://www.apple.com/quicktime/

Nokia N92 mp4 h.264 player

Do you have any idea how to play mp4 h.264 files in Nokia N92. If I download for example "Tagesschau file " from Nokia Podcasting there is no possible to open mp4 h.264 files in N 92. Is it possible to provide some upgrade ? J.L.

It's not a matter of downloading a codec.
You would need to transcode the videos. I.E. Use Super encoder or other tool in the PC to change the encoding to a format that the phone will recognize.
There are also some third party apps you could try installing in the N92/93 to play other types of videos like DivX.
Go to Handago.com or other on-line store and search for S60 3.0 video players.
640K Should be enough for everybody

Audio skips after rendering

Does anyone know how to correct audio that skips after rendering? The video is fine and the audio matches up to the video but the audio skips as though it is going in and out. The movie is about 2 hours long and the first few clips were fine but now it is becoming a problem. I rendered both the video and audio at the same time then I went back and rendered only.....mixdown to see if I could get it to work......no luck. Any help would be greatly appreciated.

Tammy,
If we've dropped a bit of time for this part of the edit, you now have time for more fun aspects of it.
While I will casually monitor my Meters, I spend much more time with a good set of noise-canceling headphones, listening critically. The Meters are basically to point up potential issues. With Audio, if you have not invested in a really good set of headphones, do yourself a big favor, and sneak 'em into the budget.
Glad that you got things toned down.
Now, let's go on to Lesson 02 - The Audio Mixer. Unlike adding Keyframes to a Clip, when your cutting is done, you can apply Track Keyframes to attenuate (also Pan, etc.) you Audio Tracks to suit. One would just change the Send in that Track to Write, or Touch, and "ride the gain" with the slider, as is required. I probably do most of my Audio editing there, than addressing the individual Clips. First thing that I have done is cut back a bit on the frequency of the Track Keyframes in Edit>Preferences, as I find the default to add too many (and you can go in and adjust these by hand, if you need to "smooth" things out a bit.). One caution: do this when you are satisfied with the cuts, Clip placement, etc., as these Keyframes are applied to the Track. If you were to remove a Clip, and replace it, those Keyframes would apply to that new Clip, whether you want them to, or not. This trips some folk up, if they do the Audio Mixer thing too soon in the editing. Wait until you are "in love" with your Timeline otherwise. It's like scoring a Project. One does that as about the very last step, or much work will be repeated, and that is not fun.
Good luck,
Hunt

ATV2 Video pixelated and audio skipping

I don't think this is the same as the flickering issue or the frame dropping issue discussed by others. Thus, the new thread.
When streaming videos (movies or TV shows) from itunes to the ATV2 the picture will get pixelated with the missing portions turning green. The video will continue but the audio skips (exactly like a needle on a record player skipping back). If I exit the video to the menu then resume, the video plays fine for awhile until the problem arises again. To give you an example of the frequency, it happened about a dozen times during one 40 minute episode.
All software is updated to the latest versions and all hardware has been restarted. Content is encoded using handbrake using the ATV2 preset and then passed through MetaX for tags. The setup is as follows: stored on DROBO->firewire->iMac->802.11n(5Ghz)->Airport Extreme->ethernet->ATV2.
Anyone else having this problem?
Thanks!

Haven't been able to see a pattern yet. I can watch a recently encoded movie (1-2hrs) without it happening once, but like I mentioned, it happened 12 times during a single 40 minute tv show. Both were encoded using same version of handbrake and ATV2 preset.
How do these two files compare in terms of total average data rate?

LG G2 mp4/h.264 not working on LG G2

Mp4/h.264 videos(All websites) do not play properly on the LG G2 with KitKat 4.4.1 or 4.4.1. I have tried both the regular Firefox (32.0.3) and Beta(33.0), both seem to be having the issue. Playback works fine using mobile Chrome. Please also note, I am not using Flash player, these are standard html5 videos.
Here is an example: http://www.quirksmode.org/html5/tests/video.html

hi battleskull
is this [https://bugzilla.mozilla.org/show_bug.cgi?id=1052888 bug 1052888]?
this sounds like an LG specific issue. those videos work fine in Firefox for Android 32 on my Samsung Galaxy S5 and Nexus 5.
I will try and get developer attention onthis.

Only half of some iTunes Matched songs on my iPhone will play, then audio skips to next song in playlist!

Several (maybe 5%) of iTunes Matched songs on my iPhone do this... at EXACTLY 1/2 way through the song.
EXAMPLE: At 2:25 of a 4:50 long song (Shania Twain - From This Moment) the next song in playlist (Taylor Swift - Tim McGraw) starts as the audio skips to beginning of next song in playlist. Oddly, Shania's attractive album artwork and title stays up while Taylor's tune plays (?)
When the timeline for the first Shania song hits the end, the artwork slides to Taylor Swift's CD Cover art and the timer slider adjusts to near the end of that song.
When I play same songs on the same playlist on iTunes (also downloaded from iTunes Match) this does not occur.
Does anyone else see this happen or are there any suggestions?
THANKS
geo

Hey Guys, from my late model iPhone 4, I am also seeing my iTunes Match songs terminate playing very abruptly ...some won't play at all ...others skip to the next track after 10 seconds.
I checked the source files on my iMAC, and they are 100 percent perfect.
Tried deleting them, recreating them, signing out and then back into iTunes with Match On & Off, etc ...still no resolution to these problems.
Maybe the MATCH product is crashing under it's own weight now? It used to be good, but now I am not so sure anymore.
Please post if you have any solution or suggestions.
Thanks!

CC2014 mp4/h.264 file error

Just updated to CC2014 and now premiere can not play any mp4/h.264 file only showing a green image. Even if you export a working clip thats a different format from premiere as h.264 and import it back in, it will only show up green. Media Encoder 2014 is also having the same issue. I've tried clearing the cache, creating a new project, restarted the pc, reinstalled the software, updated drivers... can't seem to fix it.
Here's a screenshot:
I was going to downgrade back to the previous version but the option to select which version you want to download has now either been removed or is not working on the site.

I'm not seeing that here. Such files work fine.
You might try looking at the graphics card/driver.
If you care to upload a problem clip, I can test it here.
