Compressor 3.5.3 cannot output an H.264 mp4, so you must be using an actual mpeg4 codec setting, which typically isn’t the norm. H.264 is the go to codec for uploading to web. File size is largely dependent on bitrate, so yes your MP4 is smaller, but you also say you’re getting pixelation and artifacts, meaning your bitrate is too low. You’re trying to encode a 90 minute 1080 video, it’s going to be a large file. Creating a file with a bitrate of 8,000kbps is still going to give you a 5.5GB file. You could scale the video down to 1280×720, encode at 4500kbps and still get a 3.13 GB file. Then Vimeo is going to re-encode your video. You typically want to give them a high bitrate file since they re-encode.

Encoding speed all depends on your hardware specs, but I really don’t think it should take your system 48 hours.

Dave, Larry Jordan just put out a series of articles regarding’s Compressor 4’s quality and speed, in short, it flies! No reason not to upgrade

[Bobby Hall] “I’ve read several sources online that say if you’re uploading videos to the web, the bit rate should be about 10-20 mbps”

That’s because 10-20 mbps has sort of become the standard bitrate for maintaing a good quality to file size ratio. Of course it all depends on the content of your footage, but most 1080 files will still look good at 10 mbps. For 720 the “standard” is arguably around 6-10, and for SD 1-4.

Hey Manu, choose H.264 as the Format, then choose something like Match Source High Bitrate for the preset. I only have AME CC so I’m not sure which presets 5.5 has. I would go for a CBR of 15mbps or VBR 2-pass 10 – 15mbps. You could also use one of the YouTube or Vimeo presets and pick whichever has a higher bitrate.

YouTube is always going to re-encode your file, so you want to give it as high a quality a file as possible. If your internet was fast enough I would say upload the ProRes file, but that would take a while.

Don’t use QT Conversion, export a self contained ProRes LT, bring that into compressor and do your compression there.
This tutorial is decent, put your keyframes at automatic or 30 and set your data rate to 12000-15000. YouTube will then recompress it to around 2000-3000.

If you’re okay with the gamma shift and you are pleased with your 870 MB file from MPEG Streamclip then use that. It all comes down to the eye test.

@ericstrand11

Yes, Apple’s version of H.264 is renowned for that gamma shift and overall being one of the poorest versions of the codec. Try using Handbrake, which uses the open source x.264, or Adobe Media Encoder.

Both the Samsung and GoPro shoot progressive footage, not interlaced. You can use Quicktime Player 7 > Window > Movie Inspector to find the frame rate of the footage. FCP7 will also tell you the frame rate in one of the Browser columns. Leave your audio at 48 kHz, no reason to go to 44.1. You were on the right track but sounds like you need to google and learn about progressive vs interlaced, codecs, wrappers.

As Michael said, you need to provide more information. Here is a video tutorial on using MPEG Streamclip to make an H.264.
