Here is a screenshot of my export settings window. I am trying to export a version of a music video I shot that would be good enough to be used with a projector.
I'm exporting to H.264 and as you can see my estimated file size is 868MB but my final output is actually 13MB. Could this be because I out a checkmark on "Use Previews"??
Thanks for the help
Also I meant to say Media Encoder and NOT Encore....my bad
Those file size estimates are wholly unreliable. Don't use them for anything.
Is there a problem with the export itself?
Yes my export has a very low quality. i'm always getting a file thats 13MB in size and that has a Data Rate of 289kbps and a Total bitrate of 607kbps.
How are you viewing the export, and how are you measuring the data rate?
I'm viewing the export with both VLC player and Windows Media Player. I am looking at the details tab of the file's properties menu, inside Windows Explorer, to view the file's data rate.
A week ago I exported this same music video for VImeo. At the time I used a Target Bitrate of 10Mbps and a Maximum Bitrate of 20Mbpas which resulted in a file size of 222MB with a data rate of 10058kbps and a total bitrate of 10376kbps.
The only difference I made today in the export settings compared to last week is increase both my target bitrate and Maximum bitrate, so I find it strange that I'm getting smaller files at a very low quality.
I am currently exporting the project again without having the "Use Previews" option selected to see if this changes anything.
Don't use Windows Explorer for bitrate. Instead use the Tools>Codec Information when playing in VLC and go to the Statistics tab. This will give you realtime feedback on the video and audio data rates.
The only idea I have is to use 1 pass. Supposedly there is a bug with 2 pass that might cause reduced quality.
Thanks for the information Jim its very much appreciated.
Has this 2 pass issue been going on for a while? This is the first time I've been experience it.
It's new in CC. I've haven't seen the effects in my own testing.
There is a very definite bug in the Adobe Media Encoder engine which is used in both Premiere Pro and After Effects. H.264 exports seem to randomly choose their own export quality, using 2-pass VBR. I have found with some DV-size exports on 'match quality' in Premiere Pro, that setting the export above 10Mbps pushes the quality down to well under 1Mbps, e.g. 167kbps. I've found that using the default min 6, max 8 seems to work the best. I've worked with this on two different machines and fiddled with it extensively and this is definitely NOT an intended 'feature'. In fact, I have found that exporting from the same sequence, if I select the first 20 seconds, I get very low bitrate, but if I select 30 seconds or more, I get the higher bitrate that I want! And I tend to get different results when I enable and disable 'use previews'.
I am also having some trouble with missing frames when exporting progressive animation files to h.264 mp4 files that never occured before. Not sure yet if this is related to the same issue, but interestingly, I don't get the 'blinking' missing frames issue when the bitrate drops itself down to a very low 150-200kbps. When I do get the export rate up higher, then the missing frames on just this animation clip return.
So, after my tests, here is a screen capture of sample export settings (yes, 15Mbps is a very high bitrate for DV, but the same happens at 6Mbps or 7 or whatever I try in some cases):
This gave me a 1.5MB file with a reported 167kbps bitrate and a quality level as shown below:
A currently working 'workaround' is to use 1-pass VBR which gives me a crisp, clean 5.5MB file. Would a few others please try to reproduce this so we can get it escalated to bug status? I'll report it if you can confirm it there, this is happening on two computers here.
According to Mark, Adobe has this logged as a bug.
Great. Awesome. Thanks.
