I don't make a lot of screener files but I have been using Adobe Media Encoder with QT Ref files out of Avid for various delivery files with good results.
I'm finding that if I make a QT in H_264 codec frame size 640_360 data rate 1500kbps (1.5Mbps) quality 100 the Adobe Export is much blocky compared to exporting from Avid doing a custom export.
Avid sequence is XDCam50 and DNX 175X. I render a safe color to DNX115 which is the delivery codec required. I export a QT Ref and use QT Pro 7 to do a save as. I use the resulting file in Adobe Media Encoder and get the blocks. Avid export to H_264 is soft but not blocky, which is more pleasing to the eye.
I don't do a lot of experimentation with compression etc... but I am surprised how visible the difference is given the data rate is the same.
I would think Adobe Media Encoder 2015 would have very similar results to Avid using custom export/QT Engine. Are there any under the hood tweaks I'm missing in AME?
