La capacité d'un DVD de 4,7 Go permet de stocker environ 2 à 4 heures de vidéo, selon la compression et la qualité de l'image.

Hello,

I burn a lot on 120min DVDs, that is to say 2 hours, they are 120 min 4.7GB but I can only fit 1h15 max, why is that and how can I fit more?

Thanks in advance

Configuration: Windows 7 / Internet Explorer 8.0

    Hello,

    What are you burning?

    The duration of 120 minutes only applies to DVD-Audio, just like the 80 min. indication for Audio CDs, and I seriously doubt that's what you're burning.

    Best regards

      Pour avoir 1h30 à 2h de vidéo, vous pouvez suivre ces étapes : 1. **Planification du contenu** : Déterminez le sujet de votre vidéo et créez un plan détaillé des sections que vous souhaitez aborder. 2. **Recherche et scénarisation** : Rassemblez des informations pertinentes et rédigez un script pour vous assurer que vous couvrez tous les points importants. 3. **Filmer en plusieurs sessions** : Au lieu de tout filmer en une seule fois, envisagez de diviser le tournage en plusieurs sessions. Cela peut aider à maintenir la qualité et à éviter la fatigue. 4. **Édition** : Utilisez un logiciel d'édition pour assembler vos clips, ajouter des transitions, de la musique et des effets, ce qui peut également prolonger la durée finale. 5. **Ajouts interactifs** : Considérez l'ajout d'éléments interactifs, comme des Q&A ou des segments de discussion, pour enrichir le contenu. Assurez-vous que chaque partie de votre vidéo contribue à l'expérience globale et reste engageante pour les spectateurs.

      Why can't I listen to the 4x CDs but there's no problem with the 8-12x ones.

      Thank you for helping me as I spend a lot of money trying to understand.

        Hello, there are no official standards for certifying speeds; it is often a question of firmware:

        1-24X ‘, ‘ 24X guaranteed ‘, ‘ 4X certified ‘, ‘ 8X compatible ‘... the speed indications on blank discs vary significantly from one brand to another. And for good reason: no standard governs the attribution of these labels. It is the composition of the materials used and the quality of manufacturing (flatness of the plastic discs, regularity of the groove...) that distinguishes the ‘ slow ‘ media from the ‘ fast ‘. To define the burning speed, CD and DVD manufacturers send samples of their new products to burner manufacturers, who test them. As soon as they give their approval for a given speed, the media manufacturer immediately declares it ‘ certified ‘ or ‘ compatible ‘. For their part, burner manufacturers can modify the firmware of their devices to integrate the characteristics of this new medium. When the burning software queries the burner’s firmware to find out the maximum speed of the medium it contains, it can provide the necessary information for optimal burning. Otherwise, the burning software will seek the information elsewhere. On rewritable CDs, as well as on the various types of recordable DVDs (DVD+R, -R, +RW, and -RW), the maximum speed is specified in the medium's header. For CD-Rs, it must be inferred by the software from the manufacturer code inscribed on the CD... and the length of the groove! Indeed, many disc manufacturers have gotten into the habit of playing with this parameter to differentiate their product families: 24X, 32X, 48X, etc.

    For videos, there are essentially two types of burning possible:
    - data disk burning: these are movies in AVI format, and you can fit 6 movies of about 700 MB each on a DVD regardless of their durations. What matters here is the file size.
    - DVD-Video burning: this is the format used for commercial DVDs, and in this case, you generally put one movie per disk (sometimes two, but not more), in order to preserve quality.
    For example, Windows DVD Creation that you have on your computer limits the video duration to 120 minutes, so if you want to create a DVD-Video for a movie that is, say, 2 hours and 30 minutes long, you'll need to use another software.

    Can you provide more details about your method for burning? Thanks

      No, I do not know the software available on Mac, so I don't know if I can help you further :(
      But according to the presentation on the Apple website, HERE, it is an authoring software, that is to say it creates DVD-Video.
      Perhaps watching the short videos might help you, or you could check the help section in the software.
      From what I understand, you have access to your "library" on the right, let's say the place where videos are located on your hard drive, and you just need to drag the file for it to be accounted for.

      It may limit the total maximum duration of video files like Windows DVD Maker; otherwise, in theory, for this type of software, you just need to add the files that will become the chapters of your DVD-Video.

      If the software has options, check to see if you can modify something in the advanced settings, but this is purely hypothetical.

      Good luck ;)
