Audio sync problem. I suspect this is a sample rate problem? (i am still learning)

Sorry about last message :oops:

Great!

With these settings you will get an H.264/MP4 file of 2 GB. We can push this further, but I would not go too high because otherwise the file won't play fluidly from a USB stick. USB is very, very slow

My suggestion: change the Data Rate to 15000 kbits/sec. Then press OK. The settings window will close.

Now all you have to do is enter a name and a destination for the exported file and press the Save button. The export will begin. Depending on the speed of your computer this will certainly take some time but it should give you a pretty decent quality delivery file that will be around 5 to 6 GB and that will play both on Mac and PC.

Exporting now Ronny.

Endless thanks for all your help! I couldn't have got this Assignment done without your help!

I will come back to my mac after I watch City hammer Arsenal (hopefully) lol

Got to here after 2 and a half hours of export. This came up:

How much space do you have left on your computer's drive?

-Ronny

41Gb out of 500Gb. Just moving some college stuff to external drive (5.5Gb)

46.48Gb now.

Can't think what to do to make more space?

The FCPX project and events folders are about 115Gb!!!

Make as much space as you can. To convert a 40 GB file to H.264 your system drive needs at least 50 GB of available space for caching the temp file. You get this error message when your drive is almost full, which happens at around 5% of your total drive capacity.

Here's from the Apple support pages:

"Symptoms: When sharing to a QuickTime movie, Apple Devices, HTTP live streaming, or AAC audio, the following alert may appear "Failed: Quicktime could not access a file. Offset too big."

Resolution: This alert message indicates that the drive you are exporting to is getting full. To address this, clear up some space on your hard drive or share to a different drive with available space."

So you will need 40 + 25 = 65 GB to be really safe if you store the exported file to your system drive. If you have an external drive you can temporarily move some large files onto this drive, then start exporting again. Or you can export your H.264 file to that external drive.

Whenever you delete files to make space, don't forget to empty the Trash Can. If not the space is not made available.

I've just had another failure Ronny,

Tried exporting to external (459Gb free of 1Tb). Tried copying master file to external THEN exporting QT7 H264 to my iMac main drive.

Made space on my iMac this morning so I had 140Gb of space and tried the same QT7 N263 export (data thing at 15000 again).




I don't understand why I am still getting this error message after making all this space???

"41Gb out of 500Gb."

500GB drive must have at least 75GB of free space minimum to function properly. That would not include space needed for writing new files. All drives must maintain 15% of their total capacity ass free space, otherwise you can run in to odd system wide issues like this.

Wow, my friend. Seems you are getting every misfortune that can happen

If you have enough drive space the -2125 message also can indicate bad time code in your original clip. This is always at the very start or the very end of your file. To fix this:

Open your file in QT player. Look at the start of the video and at the end.

If you have a long black image (> 1 sec) before the video and audio actually start: press I to set an In trim-point just after the black.

If you have a long black image after the video and audio actually end: press O to set an Out trim-point.

With your trim points set, choose Edit > Trim to Selection, the press CMD+S to save your trimmed movie and try exporting again.

Quicktime 7 has just come up with the same error message!!!

No point me posting a screenshot.

Don't give up yet, this has to work. There obviously is something wrong with the master but we may be able to fix this.

Do you have MPEG Streamclip? This app can fix tc breaks and you can also export with it. I think the best thing we can do is to first create a new decent ProRes 422 stereo master and use that master for exporting.

If you don't have MPEG Streamclip: download it here and install it (it's free):

When you have installed it, post back.


-Ronny

Done that.

Select File > Open Files and choose your master file in the Finder window. It will open in MPEG Streamclip. Does it open okay or do you get any warning messages? If it opens without any warnings, does the file play correctly in the Streamclip Viewer?

Ronny

File opens ok and plays ok in the viewer.

Okay. We could try exporting to MP4 straight from Streamclip, but that will take long again and if you get any more error messages you will have to start all over again.

So here's my suggestion: we are going to make a brand new ProRes422 file with stereo audio first because I think the false 5.1 audio information inside the current master could be causing the export errors. Making a new master file will be much faster than converting to MP4, and if you can successfully make a new master without getting any errors you will also be able to make an MP4.

Here's what you do:

Choose File > Export to QuickTime



In the Export Settings window that opens set the settings exactly as you see here:



Then press the Make Movie button. Give the new file a name, set a destination for it and press Save to start the encoding. I don't think this will take very long, it all depends on the speed of your computer.

When it's done, post back.


-Ronny

It's just finished!

Successfully created a 38.73Gb file.

Perfect! This should be your final step now:

In MPEG Streamclip choose File > Open Files and select the new master file to open it in Streamclip. Check if the file plays correctly.

Then choose File > Export to MPEG-4, the Export settings window will open.

In the Settings window set everything exactly as you see here:



Press Make MP4, give the exported fine a name, set a destination and press OK. If everything goes well this will finally give you a 6 GB MP4 file for your USB.

Good luck

Just a quickie Ronny.

Limit Data Range when I set to MB/sec it shows ~28 GB

i changed it to Mbps and it says ~3.4 GB

??

Does this mean I will end up with a 28Gb Documentary? Or am I just getting confused?

I tried different figures in the MB/sec box. 2 MB/sec is the closest it gets to 8Gb it shows ~5.7 GB.

set at 3MB/sec and it shows ~8.5 GB.
