![]() So, could experiment with this to find the right file size. ![]() So in this case 72 "megs" is about half the size of my original video, I can make it even smaller, make it about 40 "megs" by making it 1000 kilobits per second. Now all these other settings really don't affect it they're all about quality, this is saying exactly how much space per second of a video that it's going to use. You check that, and you get to set a kilobits per second, so lets set it at say, 2000 and you can see here on the right it gives me the approximate size of the video. So, the most important setting here is Limit Data Rate, this is where you can actually make your file smaller. Now some of the transitions, some of the special effects from iMovie won't look as good with these settings so probably in your final video you want to crank it all the way up. If you're in a little bit of a rush, or you want to try out some different compression rates you may want to have it a little bit lower. The next three settings here are all about quality, so you're trading speed at which you can process the video for quality, so if you have all the time in the world to make a video you might as well crank it up to 100%, turn on Multipass turn on B-Frames. So I want to use the H 264 compression, that's pretty standard now. So I'm going to start by dropping the video into MPEG streamclip and it'll apear in there, than I just simply go to file and one of the export options, now I want to export to MPEG-4 for the most compatibility and IO get this window here that has all the different options. If I select it, and get info on it you can see that the file size is 139 "megs" and I want to make it a little bit smaller without losing too much quality. So here I'm running MPEG streamclip and on my desktop I have a video i'ts actually an episode of MacMost Now, directly ecported from iMovie. Well you can use a free program called MPEG stream clip to compress the video even more than what it's compressed to when it comes out of iMovie. Maybe it's over the size limit for a service you're uploading the video to, maybe you need to send it to somebody or maybe or maybe you need to put it onto a disk and it's just too large. So we get asked this question a lot, you create a video in iMovie and you end up with a file that's just too big. Video Transcript: Hi, this is Gary with MacMost Now, on today's episode let's use MPEG stream clip to compress video. In my workflow it's the go to encoder if I need any kind of file I can't make in HandBrake.Check out MacMost Now 571: Compressing Video With MPEG Streamclip at YouTube for closed captioning and more options. ![]() Unlike HandBrake, MPEG Streamclip not only supports ProRes 422, but just about anything else you can throw at it. ![]() It can output to DV, AVI, QuickTime, MPEG-4 (including H.264), and any QuickTime-compatible format installed on your system. But if your making more than H.264 MP4 files, then it's just what you need. Okay, it hasn't been updated since 2008 and, unlike HandBrake, comes with no presets. MPEG Streamclip may have an unwieldy name, but the application is dead simple to use. To date HandBrake does not support ProRes 422, so it makes things a little tricky for FCP users exporting ProRes 422 timelines. And, it only produces H.264 files, so has limited use as a general-purpose encoder. In the user interface, the resolution controls are totally separate from the encoding controls, which feels a little disjointed. This is my encoder of choice when encoding MP4 deliverables for clients. In my opinion, HandBrake produces the best quality of all free transcoders out there. It uses the high-quality x264 codec, with lots of configuration options and a really good preview function. HandBrake bills itself as an open source, multiplatform video transcoder that comes loaded with a diverse range of iOS encoding presets and runs on Windows and Macs. If you are trying to decide which ones are right for you, I thought I would weigh in on two of my top choices: HandBrake and MPEG Streamclip. Exporting and uploading don’t need much explaining, but the Transcode step of that process requires a 3 rd party encoding application. Getting videos into your account is a simple, 3 step process: Export, Transcode, Upload. In addition to allowing ScreenLight to be used on handheld devices, this change also simplifies the process of preparing your videos for upload to ScreenLight. ScreenLight has recently introduced server-side encoding for all of our user’s videos.
