This will automatically compress the file - it will work out from the size of the file at what bit rate to write it so that it exactly fits. Are the files you have that you want to burn, are they VOB files? If so, go into Toast Video, and choose DVD video from TS video files AND THEN CHECK "FIT TO DVD COMPRESSION' which is the option a bit further down in that window. ![]() ![]() and with reducing the amount of information, so we lose some video quality.īack to your problem. The key word is bit-rate: we are writing/using up only 5,000 bits/sec instead of 10,000 (that is, only taking up half the room on a disc for every second), because we have reduced the amount of information we are using from the original file. If the file we are going to burn has been recorded so that it takes 10,000 bits, but we compress that file (drop some of the information, such as half the lines), it only takes 5,000, so we can fit twice as much on the disc. But say.just say.if each frame is made up of 720 horizontal lines that together form the video picture, but we only use every second line, we only need half the amount of information to form the picture. Now, all the information that goes into making each frame of a video has been encoded, and obviously, the more information used to encode each frame, the better the picture. So, each hour can only take up 5,000 of those bits. The problem really is, how to I cram 2 hours of video, which would need 2x 10,000 bits, that is, 20,000, into a space that only holds 10,000. When you say, how do I make it write faster so more fits on - it doesn't matter how slow or fast your recorder speed when burning the disc, that disc only holds 10,000 bits. A DVD player (which plays every disc at the same speed), takes 1 hour to read 10,000 bits. a disc can hold 10,000 bits of information, tops. If any one file, or combination of files is too big (more than 4.3), it makes a tremendously good job of the compression process so that it fits exactly on your DVD, writing to a file that you just drag into TOAST and let it burn. DVD2One will allow you to combine those into one file so you can burn on the same disc. For example, say you have a program you've recorded in one file on your desktop, and similar in another file. ![]() To get all your show on the disc : the solution above is trying to use TOAST itself in automatic mode to compress.Īnother ?better way? - is to buy DVD2OneX 2.0.5 if you are ripping and burning DVD's. Mpeg2 IS the format in which all data is compressed before burning to a DVD. It's when you start going beyond 2 hours that the loss of quality becomes more and more apparent. To record for 2 hours, it writes at 5,000 - half the bit-rate, but in practice, you can't notice any visible loss in video quality. My machine writes at 10,0000 bytes per second if recording for an hour. Your disc may say it holds two hours - in fact, I have a recorder/player with in-built variable rate of writing to a disc that I could.I could.get 8 hours on it. Firstly, if you mean by nearly 5 gb that they are 4.7, then remember that a gb as a number is a billion but that computer-wise, there are 1 073 741 824 bytes to a gigabyte, so that each DVD is actually 4.3 computer gigabytes, and without compression of the source data, holds an hour.
