No. One license code is for one computer only. If you want to get additional licenses for more than one computer, then contact us. We'll offer you a multi-license discount.
If you forgot or lost your registration code, don't worry, just go to the license retrieval page to get back your license code.
If you want to transfer your registration code to another computer, we can reset the registration code for you and then you can register the program on another computer again. Please send your order number and billing email address to the support team.
This process will only work with computers using the same operating system (either two Windows PCs or two Macs). If you want to use the same program on a computer with a different operating system, you'll need to purchase a second registration key for the other OS.

There are many factors that can affect the speed of conversion:
• The length and the size of the source file.
• Settings for output files, such as resolution and video bitrate.
• Computer configuration.
Here are some tips that can help to speed up the conversion:
1. Open the program and go to "Preference" windows. Then, enable NVIDIA GPU Acceleration, enable Intel App Acceleration and Enable AMD APP Acceleration. Please note that the Mac version doesn't support GPU acceleration.
2. Don't run other programs on the computer while converting.
3. The higher parameter of resolution, frame rate the source video has, the longer it takes to convert it. If you want to speed up the conversion, you can choose or customize the Minimum parameters of Resolution and Video Bitrate, but the quality of your video may be affected.
The output file size depends on the source file length and the output settings. The higher the output video settings you set, the larger the output video you will get. If you want to get a small size of the output profile, you can choose or customize the Minimum parameters of Resolution and Video Bitrate, but the quality of your video may be affected.
