Have you updated 13 to 13.1 yet using an opened project's Help Menu/Updates? If not, please do that.
What are the properties of your source video and what project preset have you (manually) or the project (automatically) set as the project preset to match the properties of the source video? Please tell us what is listed for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio (even if the fields look grayed out)
under Edit Menu/Project Settings/General.
You wrote "...everytime I publish it, the resulting video opened with quicktime cuts out some of the audio...." What are the details of your export choice...
then what selected under Presets
and are you using the default settings for the preset selected or are you customizing the export settings under Advanced Button/Video Tab, Audio Tab) of the selected preset?
What is your player - QuickTime (latest version)?
The matter of the invalid disc name has come up before in these threads (not v13 that I have seen) where the user has been put through multiple drills in search of a solution.
In one of these threads, you could find included
a. burner is not supported...have you been able to do a successful burn to folder?
ImgBurn is a popular free software to take the VIDEO_TS from the saved folder to disc, but that is a Windows only program. Does Mac come with Disc Utility that will allow you to take the VIDEO_TS Folder to DVD disc?
You could try an uninstall, ccleaner run through, reinstall.
Please review and consider and then we can consider what next based on the details in your reply.
Thanks for the reply and further information about your issue.
1. Publish+Share/Computer/MPEG2 with Presets = MPEG2 1920 x 1080i30.
That would be expected to give you a MPEG2.m2t 1920 x 1080 @ 29.97 interlaced frames per second export.
The expected file size and the duration of the export is 3091.75 MB (about 3.1 GB) and 8 minutes and 12 seconds.
a. What is the description of the files that you put on the project's Timeline and pointed it to the MPEG2.m2t export? Your project preset is NTSC AVCHD Full HD1080i30. That could reflect the properties of your source or a mistake by the project because it did not analyze you video properties correctly. Telling us the brand/model/settings for the camera that recorded the video would help to figure out the details of the project preset.
b.. Do you have the latest version of QuickTime installed on your Mac computer?
c. How much free hard drive space is there at the Save In location that you designated in the export settings? Is that a external hard drive?
Your problem seems to be that the QuickTime player does not play back this export with all its audio...what is missing
x seconds/minutes for the start
x seconds/minutes from the middle
x seconds/minutes from the end
Let us work on the above.
I am working with a canon 70D, I converted my audio to AAC which seemed to work, now when i go to export as AVCHD every time it stops with about 5 seconds left, I'm guessing this is because I need to update, my external has a lot of space but even when I move in use footage to it, premiere cannot locate it and displays an offline image
I am about to call it a day. Will revisit your thread in the morning morning.
But, I would check to determine what the format is for the external hard drive connected to your Mac Computer. A change in that format may help with the external hard drive issues. See if the following offers guidance for this
