Convert large HD file to under 2 GB
I have an 18 minute short that I want to submit online to a festival that requires the video to be under 2 GB. Right now, it’s 18 GB, 1920×1080 prores 422. I’ve tried different ways to get it under 2 GB, but I can’t seem to do it. I’d like it to be 1280×720 and look really good. How can I do this is mpeg streamclip?

Set the video codec to H.264, change the data rate to 2500 and you can keep it at 1280×720.

Spencers suggestion is a good one. In MPEG streamclip there are some presets for Apple TV which are H264 MP4. Never had an issue with quality or PC/Mac compatibility.
There is a 720 preset and I have always found these to be good quality conversions at a reasonable bit rate. Basically its pretty much the same quality as you would get from a movie downloaded from iTunes.
Hope thats helpful.best wishes

If you are using compressor or something like that, be sure to pay attention to the key frame setting in the H264 conversion.
If you have a lot of fades or composites or effects or the like. Or rapid camera movements. Or a few other things….then you will want to do a keyframe every few frames. Otherwise you can get weird compression artifacts.
It’s basically a keyframe every X number of frames. Lower that number is higher quality, bigger file size. So just play with it until you like the output and file size.

Thanks guys.
I played around with the bit rate settings in MPEG streamclip and got the video under 2GB with the bit rate set at 6,000 kbps.
