The higher the speed, the faster the copying process will be. However, higher speeds can also result in lower quality video and audio.
Here are the most common dubbing speeds and their corresponding quality:
• 1x: This is the slowest dubbing speed, but it produces the highest quality video and audio.
• 2x: This speed is twice as fast as 1x, and it produces good quality video and audio.
• 4x: This speed is four times as fast as 1x, and it produces acceptable quality video and audio.
• 8x: This speed is eight times as fast as 1x, and it produces poor quality video and audio.
The best dubbing speed to use depends on the quality of the VHS tape and the desired quality of the DVD.
If the VHS tape is in good condition and you want the best possible quality DVD, then use a lower dubbing speed.
If the VHS tape is in poor condition or you are not concerned about the quality of the DVD, then you can use a higher dubbing speed.
In most cases, a dubbing speed of 1x or 2x will produce excellent results.
