However, it is not possible to record data of 4.7 GB or more on both sides at once, so in that case, it is necessary to divide it into capacities of 4.7 GB or less, record on one side, then turn the disk over and record on the other side. there is.
Some DVD-Rs and DVD + Rs have a capacity of 8.5GB on one side, which enables single-sided dual-layer recording.

Also, when recording a video on a data CD-R / RW, it depends on the bit rate, but as a guide, if it is in MPEG1 format, it can be recorded with almost the same length as a music CD. DVD-quality video recorded in MPEG2 format can be recorded at 700MB for about 11 minutes and at 650MB for about 10 minutes. The MPEG1 format can be played with the Windows Media Player that comes standard with Windows, but the MPEG2 format currently requires dedicated playback software.
A single-sided 4.7GB DVD takes about 2 hours in standard (SP) mode.
The 8.5GB single-sided dual-layer recording type takes about 3.6 hours in standard (SP) mode.
The time that can be recorded varies depending on the content of the video. If the video has a lot of movement, it will take a lot of space, so the recording time will be shorter.
