    Hey guys...
    I am really sick of it... I tried 3-4 video converters, like xilisoft iPhone video converter 3, MediaCell Converter, apex iphone converter, but they convert small videos good. but if the video is lengthy approx 90 min. then i am not getting the desired results, the video (after conversion) looks great at the begining but it lags audio when approches to the end...

    I use these settings for the conversion

    Video:

    format: mp4
    Bit rate = 1200 kbps
    Dimensions = 480 X 320
    Frame rate = Auto (most of the times)

    Audio:

    format = mp4,aac (sometime)
    Bitrate = 128 kbps
    Channels = 2
    Stereo

    Any help from you guys ??? Can you suggest me the best settings to convert the video...

    Thanks much guys

    Maybe you should try some of the other converters? Videroa, CloneDVD Mobile or Handbrake come to mind. I have used Videora and CloneDVD Mobile with good success. I've never had the "out of synch" problem. (knock on wood)

    I'll try Videora today. CloneDVD isn't free (Since I've just purchased a video converter for $29 ---> it was a waste of money

    Handbrake is cross platform.

    Yes... I found the solution !!!

    Hey Guys,

    I was facing many problems regarding video, audio synching... Well I tried these settings in 2-3 video convertors like xilisoft iPhone video convertor, Free Video To iPhne convertor (DVD Video Soft aka), and one more... And WOW each one gave video without synching problem...

    Movie Converted: X-Men (Duration: 01:44:00) Original Size: 780 MB format: AVI

    Settings: Using xilisoft iPhone video convertor

    Video:

    Bit Rate: 1530 kbps (1.5 mbps)
    Resolution: 480 X 320
    Frame Rate : 24 fps
    format: mp4

    Audio:

    Bitrate: 128 kbps
    format: AAC
    Channel: 2

    Output: A nice quality video with size: 0.99 GB
    Time taken to convert: 28 minuntes

    Settings: Using Free Video To iPhne convertor

    Video:

    Bit Rate: 1500 kbps (1.5 mbps)
    Resolution: 320 X 240
    Frame Rate : 24 fps
    format: mp4

    Audio:

    Bitrate: 128 kbps
    format: AAC
    Channel: 2

    Output: A nice quality video with size: 860 mb
    Time taken to convert: 12 minuntes

    Another Solution Using Videora

    I noticed that the Xvid encoded sources are trickier to re-encode without losing sync.

    After a lot of experimenting with different encoders, the following solution for Videora worked very well:

    1. Add the following text "-async 1" (without quotes) to the "Additional CLI Parameters" text box when adding/editing your profile.
    2. Change the "Framerate" combo box [Purple Box] to "29.97" when adding/editing your profile.

    ... One more question.. what size of the video you get after a conversion and time taken too... for example a 90 min movie...???

    The output file size largely depends on the bit rate you use to encode.

    I am encoding at 768 kb/s at 480X320 (the native resolution of the touch). The results look ok when I view them on 57" widescreen tv.

    The file size ranges between 600-700 mb for that bit rate and resolution and 2 pass encoding. It gets much bigger when you are using rates above 1000 kb/s.

    Hope this helps.

    Cheers
