How-to & Troubleshooting & FAQ
Q: How to rename the destination file before converting?
A:Click the Destination file to rename the output file.

Q: How to speed up conversion?
A: There are quite a few factors that influence the duration of conversion:
- The length and size of the original file
- Settings for output files
- Computer configuration
And here are some tips that may be useful for speeding up conversion:
- Click Options> Preferences… to open the Preferences dialog. Find the option for CPU core. Choose the CPU core to use.
For example, if you choose 4 cores, you will own four times speed than ever when converting common audio files.

- Do not make other operations on the computer when converting.
When converting, there is a large amount of data processed, consuming intensive resource like CPU and system memory. So it would be much better not run other programs so that the resource won’t be distributed.
- Make the source file and output file on local hard disk.
If the video you want to convert is on your camera or other device, and you want to put the output video onto your portable media player, please copy the source file to your computer first, and set the output directory on your computer, too, not directly on your media device. After conversion, you can copy the output video to the device.
- The higher parameter (resolution, frame rate, etc) the source video has, the longer it takes to convert it.
Q: How to improve quality of the output files?
A: The output file quality is closely related to the quality of source files and output settings. If the source file is with sharp quality, please select larger value for resolution and bit rate for better quality (but not larger than the original’s). Or you can try the HD formats or formats for Apple TV/PSP, whose default setting values are larger.
And please note that the size for output file would enlarge along with higher settings. The output file quality isn’t better than the original’s. Better is for output contrast.
Q: How can I get 5.1 channels?
A: To export 5.1 channels with high quality, please make sure there is 5.1 channels in the source file at first.
After loading the file into the program, please choose an output format from Profile list and click the Setting button
to open Settings dialogue box.
After selecting AAC, AC3 or MP3 in the Audio Codec drop-down list, and if there is 5.1 channels available, you can get the 5.1 channels option in the Channel drop-down list. Otherwise, the 5.1 channels is not available as the output channel.

Q: How to transfer files to my iPhone/iPod/iPad with iTunes?
A: You have to save the converted files on your computer at first, then transfer the files to your iPhone/iPod/iPad via iTunes. Below are some tips on how to use iTunes:
- Connect your iPhone/iPod/iPad to the computer and launch iTunes. (If you don’t have one, please download it from the apple official website http://www.apple.com/downloads/)Click My iPhone/iPod/iPad under the devices, and select the Manually Manage Music and Videos option in the summary window.
- Click File menu and select Add File to Library option to locate your MP3 or MP4 files, then the added files will be automatically classified in the music or films category under LIBRARY.
- Click music or film under LIBRARY, drag the music and film to My iPhone/iPod/iPad. And then click music or film under My iPhone/iPod/iPad, you will see the file in the right list.
Q: How can I know my order whether successfully or not?
A: Generally speaking, once the order is processed, you will receive a confirmation e-mail sent from Avangate. This e-mail which contains the registration information indicates that the order has been processed successfully.
Please look up the order status from the following link: http://www.avangate.com
Q: Why my subtitle is unreadable?
A: Please make sure you selected the correct Font and the correct code page for the subtitles. For more information on what Code page is, please see http://en.wikipedia.org/wiki/Code_page. If you are not sure what Code Page to use, please consult this page which identifies different code pages: http://msdn.microsoft.com/en-us/library/dd317756.aspx

Q: How to disable the audio or add additional audio in output file?
A: You just need to click the Audio Track button and select No audio to disable it or select Add audio… to add additional audio stream.

Q: How to get higher video quality?
A: The output video quality is decided by many factors, such as source file quality, output format, resolution, bit rate, frame rate, and so on.
If you don’t mind, please change another format for a try or make the values of resolution, bit rate and frame rate larger.

Note:
It takes longer time to convert the video if the parameters are larger. So to get a higher quality will slow down the conversion speed more or less.
