View Full Version : Video compression

10-16-2013, 12:38 PM
I have a large 3D animation that I need to get down to a size that can be emailed... maybe 10mb. I have exported .mov files at 960 X 640 p (target iPhone4) and used a conversion software to format .mp4 but the file size is still 48mb. Can anyone tell me how to get the compression higher so the file size will come down to a 10mb range. I have tried MPEG Stream Clip, Amersoft Video Converter and Wondershare video Converter Ultimate.

Dual Pass H.264 has the best quality/size ratio right now. Adobe Media Encoder and Hand Brake do a good job of compressing videos to H.264 using dual pass. I use media encoder and to fine tune the size/quality I just set the minimum and maximum target bitrates.

Thanks, I will give it a go...

You're basically going to need to work out the bitrate you need for the running time you've got (you didn't mention it) to get to a 10Mb size.

What is a good rule of thumb with the settings? I always try to get an artifact free mp4 that can play smoothly (file size not important). I never use key frames checked as it usually give me artifacts and have the bitrate close to the max for the cleanest video. Is there a better method of operation? I feel I'm just arbitrarily making settings with no real reason as to why....

I use ffmpeg. Its free and very customisable (although its command line)

For a 720p .mp4 i find 5-7mbps works pretty good. Vimeo and youtube have some good recommendations on their sites specific to what software you use to export.

Can't you use wetransfer.com or an equivalent to send a larger file? Or is that not an option?
