## Frequently Asked Questions

Q: I want to change some settings for my convertion. Where can I found them?
A: All the settings of the software can be found in the right panel of the main window. After you highlight the file you load and select the output format, the adjustable settings will be active, such as the "Frame Rate", "Sample Rate", "Video/Audio Bit rate" and so on.
Q: It is said that your software can detect and show the basic information of the file after it is loaded. Where can I find it?
A: Load your file and highlight it. The basic informations of the file, such as "Video Codec", "Frame Rate" and so on, will be shown in the preview screen.
Q: My output file is out of sync. How to solve it?
A: Please lower down the video bit rate to have a try. It can be found on the right panel of the main window. You also can solve it by adjusting the frame rate.
Q: I want to convert my 3gp files to MPEG1/2/4, but I got a "Fail" after I clicked "Encode".
A: You have to change settings to make the Encoder work. For example, change "sample rate" to "44100", "Frame Rate" to "29.97". If the output file has no sound, you need to change "Audio Channel" to "Stereo".
Q: Why do some of my AVI files can not be converted to MPEG1/2/4 and just get "Fail" information? And also, some MOV files from digital camera have the same problem.
A: AVI/MOV files might be created with lots of different video codec. AVI/MOV files with mjpeg codec have the problem above mentioned. You need to change settings to make the software work. You'd better set"frame rate" as 29.97, "Sample Rate" as "44100" to have a try. If your file is in MOV format, you need to select "2(Stereo)" for "Audio Channel" so that you can play the output file smoothly.
Q: I just want to make a clip of the conversion. How can I set it?
A: You need to set the "Start Time" and "Duration" of the conversion by entering the starting time like "00:00:00" and setting the duration, the duration sould be counted by second. For example, if you want to convert clip of 1 minute and 20 seconds, you should enter "80s" in the "Duration".
Q: I want to convert a file to 3GP, but the quality of the target file is too terrible. How can I get a better quality 3GP file?
A: You'd better set the "Video codec" to "mpeg4", which is better than others, and select a larger "Video Size" with the "True" for "Same_quality" choice. You will get a 3GP file with better quality; it is a matter of course that the size of the 3GP file would become larger.
Q: My mobile phone can only play the 3GP file with resolution 320x240, but I get "Fail" if I set it with your software.
A: You must choose "mpeg4"as the video codec so that you can succeed in conversion with the higher resolution.
Q: I have succeeded converting my video to 3GP format. It plays well on PC with QuickTime. But while I import it to my mobile phone, it is terribly out of sync.
A: Different mobile phones may have different request of "Frame Rate" for 3GP files. Most of them are lower than what PC needs. So you'd better set "Frame Rate" to a concrete number instead of the default one "Auto". Actually, you can import a file which can play well on your phone into the software to detect the "Frame Rate" by our software. The frame rate detected by the software would be the one which works for your phone.
Q: I always get "Fail" while I try to decode video files to some audio formats such as mp3 and m4a. How can I get a successful conversion?
A: You'd better adjust "Sample Rate" to "44100" to have a try. You can find it on the right panel of the main window, it is a drop-down list.
