Drifting sync with converted MP4 files

Hi there. I'm converting some MP4 files to .mov using AIC using slipstream so that I can edit the footage in FCP. I find that the sync is drifting very gradually within a few minutes. The sound is an aiff file recorded digitally at the time. Any idea what might cause this? Thanks. Should I use another codec?

Do not use ProRes HQ. It's overkill unless you are working with FILM not VIDEO. Just use ProRes 422. You will see this documented all over this forum. It was even discussed earlier today.
To the OP- A lot of people also use MPEG Streamclip (free download) to convert files to editing formats. Not that there is anything wrong with Compressor. I just want to point out another option.
What sample rate was the audio recorded in? 44.1khz or 48khz? If it's the former it would explain why your audio is drifting. Try using QT to convert to 48khz AIFF 16 Bit

Convert mp4 files to mov

I have recently succeeded in using compressor to convert mp4 files into mov files using the h264 settings. however, this is no longer working due to the bugieness of compressor. I have also tried it with Media Encoder but that creates files three times the size of the original.
Any one know of anyother way to do this?

Sure. No argument there. But you have to work with the files given to you from the clients. In this case MP4's encoded in such a way that the audio remains compressed on the timeline. Converting the files to mov is the quickest conversion process.
Also the final product is for web streaming anyways. I have considered converting just the audio but it's easier file management and it also avoids sync issues.
So yeah anyways now I'm using Media Encoder the conversion is faster and more dependable than compressor. I also now limit the bit rate to 2000 kpbs/sec to keep the file size of the converted file from slowing down the editing process. the resulting file sizes are not much smaller than the original mp4 files.
Seems to be the best solution so far. Batch convert at night and edit during the day.

Can I convert mp4 file to use in iMovie without buying software

mp4 is a container, no 'format'.
could contain HDef too (Streamclip should convert to QT/AppleInterediateCodec)
could be imported to iM without conversion
could be handled instantly with usage of perian.org plug-in
could not be handled on MacOs anyhow ...
.. depends on, what's inside the mp4 ............

Converting mp4 files to mp3 files

could someone tell me how to convert mp4 files into mp3 files? thanks

Now this is clear.
You didn't have an .mp4 file or even a .m4a file. Yours is .m4p.
The "p" stands for protected.
The rules say you can burn your .m4p files to CD. The CD file will be in .aiff format.
Drag the .aiff file into iTunes and then "convert" (using the options in your preferences for bit rate and extension).

I need help with Compressor 4 settings to convert .mp4 files to .m4v for iBooks Author

I'm a curriculum design guy with no video background. I have Compressor 4, but don't really know much about how to best use it. I'd appreciate some help with getting the right setting for my project. Screen shots of settings would be much appreciated, since I don't know much video terminology.
I'm making an free iBook for students on WWII propaganda using old videos from the Internet archive.
I'd plan to use Compressor to:
1. Convert the .mp4 files to a .m4v that iBooks Author will accept. (I know I can use QT for that, but it increases file size)
2. Use Compressor to reduce file size so my iBook doesn't get too big
3. Get videos that look & sound the best, given the poor quality of the original source videos.
Here's some sample videos that I'll use:

http://archive.org/download/AvengeDe1942/AvengeDe1942_edit.mp4
PS - I will also be editing some of the original videos in iMovie - if I use different settings to prep those videos for iBook Author, let me know.
Much thanks in advance for any help

Converting MP4 files with 5.1 sound

I tried using Videora, Xillisoft and Cucusoft's converters, but all of them fail converting my MP4 files with 5.1 sound.
I don't mind losing the other 4 channels, but can anyone tell me what program can convert them?
BTW the files were created with NERO.

Saw this somewhere:
Ok, I managed to get Dolby Digital from a Video file. The steps are very easy:
Create an mp4 from your DVD or other source with Handbrake or Visual Hub - Audio Settings are not important
If you are ripping a DVD then open Mac the Ripper, choose Chapter extraction, open streams and select the Audio File you want to be extracted
You will now need Quicktime Pro
Open both files (the mp4 and the ac3) in Quicktime. Copy the ac3 stream and paste it to the mp4 file
Save the file as a MOV movie
Import it in iTunes
That was it!!!
I am now trying to figure out how to extract ac3 audio from mkv files...

Problems with importing mp4 files into iTunes.

Hi all,
Since a few days I am the proud owner of an iPad 2. When I was looking for a solution to sync my video files (no problems with my pictures nor with my music files), I saw that I had to convert them from .avi to .mp4.
Through this community I learned that there were several free and paid options. Such as handbrake, convertavitomp4.com, etc etc
In the end I have tried around 4, but when trying to get the files into my library of iTunes it fails. In the beginning I did not receive any error message. It just did not work. I tried through CTRL-O, drag and drop. Nothing seems to be working.
Does it have something to do with the fact that I have the newest iTunes (10.5) and the latest OS for the iPad?
Does anyone have The same experience or knows a solution?
Thank you in advance,

Hi Swen,
I am checking out flex player after your recommendation. However, I have since resolved my problem. I am running windows 7, 64 bit, and discovered that the problem was windows 7 security settings. All my itunes data was on a hard drive that I plugged into my new pc running windows 7. Despite allowing me to access the hard drive in the usual way, I discovered (after some help from someone more knowledgeable) that the problem was that all my itunes data was protected and I did not have "full control" rights in the security settings. Very odd, given that I have only one user account on the pc. And why it could not tell me what the problem was I don't know. But what I did was right click the drive and make sure my user account had "full control" rights and now I can drag and drop movies into itunes. This may not fix your issue but hope you resolve it soon.

HELP: I have an impossibly long rendering time after converting .MP4 files from Go Pro Camera to .MOV on Final Cut Pro 7. PLEASE ADVISE.

I am working on a project and shot guerilla style footage with a Go Pro camera, which produced .MP4 files incompatible with FCP7. When I converted the files to .MOV, I realized the rendering time in the sequence editor is impossibly long. I am working with a deadline and the rendering time exceeds the deadline, let alone editing time. Suggestions???

Telling us you converted to .mov doesn't tell us much. MOV is a container that supports a very wide range of codecs. It is the specific CODEC that matters.
You most likely did not convert the material to a FCP7 native format. ProRes is recommended and, given the compression of the GoPro, ProRes LT would be the best choice.
Use Compressor to convert everything to ProResLT and life will be much simpler.

Problem with transferring mp4 file to iPod Video

I used MediaFork to rip a DVD (that I own) to mp4. It looks great on my iMac and MacBook when running in QuickTime. I can import the file into iTunes.
I can play the file from within iTunes. However when I sync content to my iPod it does not show up!
When in QuickTime the following information is displayed in Movie Info.
Format: h.264 Decoder 640 x 480, Millions AAC, Stereo (L R), 44.100 khz
Data rate 1610.00 kbits/second
Every once in a while the Playing FPS changes to > 24 (like 24.10)
Is the data rate the problem??? Or what else could be the problem?
Help!
This is from the Video IPOD video specifications.
H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per sec., Baseline Low-Complexity Profile with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats;
H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per sec., Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats;
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per sec., Simple Profile with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats

The data rate you mention (1610) is over the published spec (1500), so I would guess that is indeed a problem.
Also, in MediaFork, did you set the encoder to the option marked for iPod?
If not, that could be a problem. Output from the encoder labeled MAIN won't work on an iPod.
Settings I use succesfully –
File format: MP4 file
Codecs: AVC/H.264 Video / AAC Audio
Framerate: Same as source
Encoder: x264 (h.264 iPod)
2-pass encoding: yes
Quality: Average Bitrate 1250

Problem with reading mp4 files with QT 7.4.1 or mpeg Streamclip

Hi,
I used to convert some .flv files into .mp4 files with iSquint and then into .dv files with mpeg Streamclip in order to re-work and compile these files on a DVD using iMovie and iDVD.
However I cannot do it anymore since I upgraded to QT 7.4.1. iSquint uses the mpeg-4 video codec to convert the file. Therefore I cannot open them with QT 7.4.1 anymore and I cannot convert them into .dv files with mpeg Streamclip anymore since Streamclip is uses a QT plug-in.
I have tried to solve the problem using Perian but this plug-in does not work with my version of Mac (Panther 10.3.9). I also tried to downgrade to an older QT using Pacifist but it nearly crashed my whole computer (fortunately I could fix that by reinstalling QT 7.4.1).
Has someone a solution to my problem?
Thank you in advance.
Steve

Not all the following will apply to Panther (10.3.x) so look carefully on the sites mentioned for the correct versions:
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 or 7.4 and OS 10.4.11. (If you are running Leopard, ensure that all plug-ins have been updated for OS 10.5)
Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11 or Leopard, that you have downloaded and installed the correct version for your Mac of Security Update 2007-009.1.1, which also deals with the Quicktime/Flash issues you may have experienced, such as the '?'. What happened was that both Quicktime as well as Adobe FlashPlayer tried to play the Flash video at the same time. This no longer happens. (N.B. Security Update 2007-009 1.1 requires both a restart and a permission repair.)
If you get problems with viewing video on a website try moving this file to your Desktop:
Hard drive/Library/Internet Plug-Ins/QuickTime Plugin.webplugin
and then restarting Safari. If all now works, you can trash that file.
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

I can't convert mp4 files to prores...

Hey guys...
I can't seem to convert h246 file to prores...with mp4 file...
I don't know what to do...but i had no choice but to work with it for time being..

It won't let me convert to prores...i went to youtube and all that..and I had no problems with mov. file...
but this is bugging me out..i'm using gopro to record...any help will do. thx.

Depending on how new you are to FCP and like youtube, this is very short and sweet.

You import the new files to your FCP project from the location you told compressor to save them.

Audio always off sync after converting .asf files?

Hi, my problem is that it seems that every time I convert .asf files the audio always ends up off sync. Many programs don't even convert them at all, like ffmpegX, but my favorite video converter VisualHub does convert, but like I said before the audio is always off sync. Does anyone know of any software that can reliably convert .asf to another video format without the audio messing up?
On a side note, I do have plug ins such as Perian and Flip4Mac that allows Quicktime to read the files just fine, it's converting them that causes problems. For reference, the particular files I'm having trouble with use the WMV3 video codec and wmav2 audio codec. I think that's the problem.

My problem is a bit different, though just as irritating. I can't believe Adobe hasn't fixed this given how long since the original post has been up here. I capture satellite programming from a professional c-band satellite every week. I use good old fashion Quicktime to capture 30 minute programs for later broadcast. Our job is to capture the video from the satellite, clip the commercials at the beginning and end of the program and then export a clean version as an MPEG2 file. Quicktime provides two capture settings: high (which provides a very large ProRes file in 16bit stereo) or medium (which provides a manageable H264 file in AAC stereo). Both are Quicktime files.
While I don't have sync issues with the ProRes file, the file that is captured using H264 and the AAC stereo gets pushed out of sync by just enough frames to make it necessary to fix. This is adding about 2 to 3 hours of studio time each week to our production given we have to process about a dozen of these files. Viewing the original quicklime files using the newest version of quicklime or the old Quicktime program and most other video players yields a perfectly in-sync experience; it's just when it's imported into Premier Pro CC 2014 that the sync. problem appears. One solution that has worked is taking the master file and exporting it again as a .dv file, but this actually takes longer than fixing the sync issue within Premiere. My guess is it may be the AAC audio process that may be the problem.
We only started using Premiere a few months ago and are already re-evaluating whether we should return to FCP. We were really like most of the Adobe apps within Creative Cloud, but we use Premiere to much to put up with such a major flaw. I do wish Adobe would monitor some of these forums; they have no idea how customer service plays a key role for future software purchases.

Pocket Playlist- how to convert mp4 file to use on pocket playlist

I have an mp4 video that i would like to use on my pocket playlist, but not sure how to convert the file?

Hello Andy,
I do not have an HP Pocket drive but according to the manual...
The pocket acts as any other drive to store files on. Its the media player that you use that has to support the type of file you are playing.
This is cut from the manual.
"File types supported by HP Pocket PlaylistYour playback device may not support all of the following formats. If your playback device does not support a format, use the ArcSoft MediaConverter 7 computer application to convert (transcode) the files into a format that will play back on your mobile device.
HP Pocket Playlist supports the following file formats:
Video: .avi, .3gp, .flv, .m4v, .m4p, .mov, mp4, .mpeg, .mpeg2, .mpg, .ogg, .qt, .ts, .tts, .wmv
Music: .aac, .ac3, .adts, asf, .lpcm, .m4a, .mp3, wav, wma
Photo: .bmp, .gif, .jpeg, .png, .tiff, .tif
You need to import files with the "Arcsoft Media Converter" which will convert the format for you.
Here are the links to all the info for HP Pocket Drives.

ITunes Library: Keep 2 external HDDs in sync with same music files

I am trying to run iTunes with 2 external HDDs, keeping in sync with each other. One large one for my desktop and a second portable one to take away from home when I need to travel. What is the best way to do this?
What I have done so far is changing the location of my media library via iTunes advanced preferences to the other ext HDD and then consolidating my library, but I noticed that it tries to re-copy the entire library or at least part of it so I end up with music files like:
Back in Black.mp3
Back in Black 1.mp3
I'm sure this has been thought of before and an obvious solution should be available, but I've never been able to find one, so I'd be really glad if someone could tell me how to do this!
