iMedia Converter for Mac
An all-in-one tool to convert all videos, decypt/copy/rip Blu-ray and DVD with high quality.
What are NTSC and PAL?
There are two television display systems in commercial use: PAL (common in Europe and parts of Asia) delivers a frame rate of 25 fps (frames per second) with 625 lines, while NTSC (used in the U.S. and Canada) delivers a frame rate of 30 fps using 525 lines.
Some DVD players only play NTSC or PAL discs, while others can play both standards. If your player gives a message “not NTSC” or “not PAL” if probably won’t work. Those who visit other countries and purchase DVD’s there may be surprised when the title cannot be watched when returning home. It seemed to me that it will be much simpler to convert the purchased DVD’s with PAL format to NTSC and watch the copies.
If your DVD player can not accept NTSC DVDs like me, you may need a converter tool which I recommend is Aunsoft iMedia Converter for Mac which can easily and fast convert DVD between PAL and NTSC formats with perfect output quality. Let me take an example of PAL DVD to NTSC DVD conversion based on my own experience.
After loading all your DVD PAL files into this program, you can simply choose specific output format for your specific need (like NTSC DVD) from Format drop-down list. Please check the screenshot below:
The conversion process from NTSC DVD to PAL DVD is quite similar. The only difference is that this time in the other hand you select PAL DVD as your output format.
You are also be able to edit your original files by clicking “Editor” button for basic editing functions like trimming, cropping, adding video/image/text water marks, replacing audio, etc.
At last, click 
button to start conversion. The conversion time depends on your selected original files need to be converted. After the process finishes, you are able to watch these PAL/NTSC DVD copies on your DVD player!
