    Hi have some footage which I do need to author. Their size is such, that I might reach the maximum capacity of my DL DVD+R (TDK). Therefore, I need to know exactly how many bytes this 8.5 GB DL DVD+R can hold.

    Is there a standard number for all DL DVD+R or does it vary with the manufacturer?

    If the number depends on the media, is there a tool which helps me to find out?

    Thanks,

    There is a standard number. DVDs are not (for th emost part) like CDs where you can have 700, 800 and even 900 MB discs. DVDs also do not over burn very well.

    You have two limits you need to observe. One is certainly the maximum capacity of the disc. The other is the maximum allowablew bitrate for DVD, which is 10800 kbps combined audio and video bitrates, with a maximum video bitrate of 9800 kbps. You will also find that quite a few DVD players cannot maintain these bitrates from non-pressed discs.

    I'm talking of the capacity restriction.

    - How many Bytes (no bitrate, not KB, MB or GB) does a DL DVD+R accept?
    - Is it brand related?

    Thanks,

    No, it is not brand related. If you bothered to read the Wikipedia link, it tells you exactly what the capacity is for the four different formats.

    DVD+R DL holds 8,547,991,552 bytes
    It's not brand related.

    You would do well to stay below that. The closer you get to 100% capacity, the more likely you are to have problems.

    Verbatim makes the ONLY reliable DVD+R DL media. All other brands are inferior.

  7. The exact number of bytes is meaningless because you can't fill that up to capacity with your movie anyway. Since you want to put video on it, and I assume you want it to play in a DVD player, you'll end up with much less than that. The authoring structure uses some of it, even if you don't have menus, and the layer break placement will also play a role in how much actual data can fit. You'll want the layer break to be at a convenient point in the movie, which will vary depending on content, and is never at the ideal location for maximum capacity, so it's hard to say how much of your movie a DL disc can hold with any amount of accuracy.

    I could have sworn I've seen apps like ConvertX make a disc that shows it has 4500 (or more) on it, which I thought was not possible. This was a rare event, but always prompted a WTF? reaction on my part. But the discs played. So, I dunno what's going on there.

    Plus the fact that the more stuff you pack onto a DL disc, the smaller the area for the layer break gets.

    The OP may not care where the LB is, but it's worth mentioning.

    There was somewhat contradictory information on that page. Therefore I asked again for the byte Number.

    DVD-9
    SS DL
    8.54 GB
    7.95 GiB

    DVD+R DL
    8,547,991,552 Bytes
    8.55 GB
    7.961 GiB

    I use TDK, but they don't produce DVD any more. Any (Windows) tool which spits out the manufacturer?

    The question came up, since I have a set of 10 DL DVDs, which I have to author. One might scratch the limit. Therefore my usual 8.5 GB was threshpassed. Therefore, I required the accurate capacity.

    I was talking of ready authored files (.vob, .ifo and .bup files). Hence, no worries any more about DVD structural overhead. It was about teh actual data available!

    There is nothing contradictory about about the numbers I supplied. It is all explained as to why there are different units of measurement, what each means, and what the true sizes are. I apologise if reading a couple of paragraphs was simply too much for you.

    That occurred to me as well. And to repeat something already said above: If one is determined to squeeze the utmost onto discs, better use Verbatims, otherwise expect stuttering near the end.

    I just go by what our 'WHAT IS' DVD page shows and it hasn't failed me yet :

    DVD+R DL
    DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 7.95 computer GB* (called DVD-9) and dual layered double sides 15.9* computer GB (called dvd-18).

    Perhaps you noticed, but just in case you didn't... ImgBurn lists the disc I.D. on the screenshot you posted as:

    RICOHJPN-D00-01

    You can compare disc I.D.s to the listings here:

    http://www.digitalfaq.com/reviews/dvd-media.htm

    But again, for DL discs, Verbatim is most reliable.
