    Help! I have an mp4 file that's 400 mb but I have to get it to 30 mb or less. I have iskyosft video converting tool.

    What is the best way or format to convert it to to get it 30 mb or less and keep the quality as good as possible? Thanks!

    Have you tried MPEG Streamclip? It offers many options and it's free.

    I would recommend using Handbrake as its UI is a lot simpler for the novice user. You will need to reduce the bitrate to 500kbps for a smaller file. However any reduction in nitrate WILL affect overall quality.

    Agreed. Handbrake is great, and much easier to use.

    Handbrake also has a 'target size' option, so OP can just type in 30MB and leave it to the app to work out how much compression is required.

    For iskysoft, it lets me convert but there's a bunch of format options and I have no idea what's what. Like I tried converting it to .avi since that sounded familiar and it did it and got it down a lot (but not down to 30) but when I tried to watch it, it had created a thick black frame around the video so it was like inches smaller on each edge, so after that I figured it was just better to ask for help.

    So with mpeg streamclip or handbrake, would I still have to pick an output format? The handbrake "target size' thing sounds like it might be what I need so I'm going to look into that, thanks!

    Why do you need to reduce the file size... do you want to post it to YouTube, for example? A little more information would help.

    Not for youtube, for a project that has to be under 30. But, thank you all, I installed handbrake and it was so easy. I just put 30 for the target size and it did everything. I still wasn't sure on output format so I kept same one and it seemed to work fine. Quality was less, but not as much less as I thought it would be.

    Easiest way and best quality hands down is using this native cloud app at godromo:

    Click on use now, and the app should load. You need java installed. All settings are autoconfigured. To change the final file size open your mp4 file and then go to preferences and use the video bitrate slider. As you move it you´ll see that it tells you the final size of the file on the top. Select desired file size. Use the iPhone 3G profile if you want good quality and smaller file sizes.

    iSquint will let you adjust the size and quality so it uses less memory :)
