Compressor pixelating my films!
on Jul 31, 2012 at 7:12:39 am

I've got two or three 4 minute films that I am trying to compress yet every time I use compressor they turn out pixelated??

I have tried so many different settings yet nothing seems to work?

They were all converted to Pro Re 422(LT) before I took them into FInal Cut Pro - I let FInal Cut change the sequence settings to suit.

On Compressor I restrict to 5000, set frame rate to 25 (have also tried the automatic settings), have turned frame controls on and off - what is going on?

Can anyone help me on this?

Thanks

Hi Gavin,
Using CompressorĀ“s "Frame Control" makes sense if you need to re-size, de-interlace or change the time-base.
I guess you are making an H264, but I donĀ“t know if 5Mbps is enough data-rate because you do not mention the picture size.
Leave "Keyframes = AUTO" and use Multipass.

thanks Ryan

I will up the data rate

Am guessing I can leave Frame Controls off as it was shot 1920 x 1080 on a 7D?

What format are you transcoding to? What's the deliverable? What's the frame size (source/deliverable)? Is there a lot of hand held camera work, fast pans, fast motion, etc?

Why are you restricting the data rate to 5000kb/s? If uploading to YouTube or Vimeo (assuming h.264) and your length is only 3-4 minutes you can easily double that data rate (I'd probably at least triple it).

Hey Ryan

Thanks for coming back on this

Am compressing to h.264 at 1920 x 1080

Am unsure what deliverable means?

Will up the data rate for sure - was unaware I could go so much higher

Do I use Frame Controls? the footage is from a 7D which shoots progressive?

I think 5000 is a pretty safe data rate usually. It's what Vimeo recommends on their Compression page ( https://vimeo.com/help/compression ). In my experience, sometimes you just have to throw a higher data rate at the video to get the results you want. The trade off being you'll have a larger file (what I would call a deliverable - you're delivering in its final form somewhere).

I just posted a video on YouTube last week with a data rate of 30,000kb/s. Yes, it was overkill. But at the same time the only penalty I incurred was a slightly longer upload time. If you're willing to wait for the upload, YouTube can choke down up to 10GB files (maybe 20GB...haven't checked in awhile). Vimeo is a bit of a different story as space there is much more limited. But @ 1080p I think you should be around 7500kb/s if not at 10000kb/s.

Just my $.02.
