Have you had any problem converting your AVI file to a MP4 format for your iPhone? Have you ever googled for some answers which could do you a favor to solve your problem? Admittedly, the key point is you have to turn your AVI videos into .MP4 format, which are accepted by iPhone. So a video converter program may be of great help. I want to recommend you Leawo iPhone Converter, which can convert AVI videos to MP4 for iPhone, and it can convert .VOB to .MP4, .WMV to MP4 as well. Let's see how it works.
Download and install this Leawo Free iPhone Converter
Step1. Open the program, and select ".MP4" in "Style", drag and drop the AVIs in the program, or click "Add" button to browse them in. Double click the file name to have a preview. Click "Convert" in the bottom right to launch the conversion, and DONE.
Tips: Under "Customize", there is "Effect" adjustment for a better visual effect, "Trim" to delete the bad spots and leave the good scenes, and "Crop" to remove the margins for a proper video dimension. This step can only support Leawo iPhone Converter Pro Version, if necessary, buy and use it; If it's not needed, ignore it.
a, Under "Effect", drag the slides of "Brightness" and "Contrast" for a better visual effect. Check "Flip" to turn the video upside down. Check the "Deinterlace" to remove the TV system video artifacts. Drag "Volume" slide to adjust the volume.
b, Under"Trim", set the "Start Time" and "End Time" points for a video length.
c, In the droplist of "Letter Box", select a "Crop" style, or adjust the offset values for a precise cropping.
What a fantastic conversion! Now you can put your AVI videos in iTunes and sync it with your iPhone. By the way, if you want to convert DVD to your iPhone, I suggest you use Leawo DVD to iPhone Converter.
