  • MPeg2 data DVD shows different file sizes on PC than on Mac

    Posted by Tom Matthies on April 15, 2013 at 6:35 pm

    I’ve exported a 28 minute standard definition program from ProRes to MPeg2 through compressor while adding a .scc file for captioning. The resulting file came out to 4.3Gb on the data DVD. It plays fine in Quicktime and using VCL Player. Closed captioning displays fine as well.
    When this same DVD is loaded onto a PC/Windows computer-we tried three different machines- the file plays but only half of it is there. If I look at the file on the DVD using Properties, it shows up as only 1.99Gb (the suspicious FAT-32 file size) While the file plays on the PC using VLC Player, only the first 14 minutes or exactly half of the program is there. It ends at 13:29. In Quicktime on my Mac, the frame rate is showing 29.97 for playback. On the PC using VLC Player, it’s showing a playback rate of 59.94. This is the same DVD used in both machines.

    Is this a Windows limitation? This program is going to be distributed to various TV stations for playback. I’d guess that they all use PC’s to ingest the file into their servers. This will be a problem.

    Anyone have an insight into this one?

    You might want to try re-burning the Data DVD using a utility like Toast that has options for making the files Mac and Windows compatible. You shouldn’t have to recompress the original…

    I did burn the DVD using Toast with the tick box set for Mac & PC compatible.

    Hi Dave.
    No Telestream. Just used compressor to encode a standard MPeg2 Program Stream for broadcast. This is the same encoding settings I use for delivering Standard Definition spots for broadcast. It’s VBR with a top data rate of about 23Mb/Sec. All I did different was to add the .scc file to it before encoding. The files playback without issue, including the closed captioning, on my Mac using either Quicktime Pro7 or VLC Player. If I look at the file on the data DVD, in the Mac, it shows the correct 4.3Gb size. When I put the DVD in my (or any) Windows machine, the file on the DVD is showing only 1.99Gb. It will play, with captioning but only the first half of the show will play. This is the same exact DVD in both cases. For some reason, the entire file isn’t showing up or being accessed by the Windows computers. I’ve tried it on a machine running XP Professional, Vista and Windows 7. They all show the same information-1.99Gb. Its gotta be some Windows “gottcha” at work here.
    There shouldn’t be a file-size limit to a data DVD similar to a disk formatted as FAT-32? The 1.99Gb size is a little suspect. The info is there on the file. The Windows machines just don’t recognize it.

    Got it working.
    Using Toast, rather than burning the Mac & PC format, I used the DVD-ROM UDF (Universal Disk Format) option in the formats menu. Disks will now mount and play correctly on a Windows based machine, including the Closed Caption info.

    Knew it was something simple…

    Weird story.

    The FAT-32 file limit is 4GBs.
