  • Feature Film Export 25 GB needs to be under 20GB – what settings

    Posted by Zoe Westley on December 10, 2015 at 5:15 pm

    Hi everyone

    I am trying to export a version of the film i am working on as a file under 20GB but retaining good enough quality for a public screening. The file needs to be sent over the internet. and will be used to create a BlueRay.

    I’ve done a video and audio mix down of my sequence – 36MXF then exported same as source – the file size comes to 26GB – which is pretty good going, but i need it to be just under 20GB. I’ve tried various different exports on Mpeg stream clip and from avid itself, and all the files are much larger, often double the size.

    does anyone have any suggestions? I’ve been trying all day and need to start uploading tonight

    thanks
    zoe

    DNx36 is an offline codec, not a screening one. Maybe fine for screening for the producers, but not as a final delivery screening format.

    Do you have ANY details from the person you are sending it to as to what they would like? Codec wise? What can they play back? Because you can export a full res (high res DNx…like 145, 185) and then use compression software to make a broadcast quality H.264 file. NOT MPEG STREAMCLIP…something like COmpressor or Squeeze or Media Encoder.

    Hi there, thanks for the reply.

    It’s just for a producers screening. the whole project has been edited at DNx36 so delivering for the screening at that quality is perfectly fine for this purpose. All they have told me is that they need me to upload a file under 20GB to burn to a BLueRay disk for the screening. The best quality i can create under 20GB. no more information.

    I have compressor 3.5.3 – what settings would you recommend i use in this software? thanks for the help so far

    Isn’t there a high quality BluRay setting in Compressor that you can use and make the file ready to go for BluRay playback?

    Hi Michael
    thanks

    I am just looking now, yes there is BluRay H264, which looks great, however it says uncompressed 8-bit NTSC video. It won’t let me change those settings. The project was all shot at 24fps. is this going to cause a problem
    thanks

    I suspect the “NTSC” is an indicator that in NTSC countries, the 23.976/24 source needs to have pulldown applied to meet television standards as you can see from the Adobe Media Encoder settings below (which I prefer using for these types of encodes). Also, the Adobe Media Encoder actually shows me what controls I have. I just launched Compressor, first time in a long time, and it has been reduced to presets only from what I can tell.

    Adobe Media Encoder Presets:

    User controllable parameters within the preset. In this case it is 1080p/23.976 High Quality. Notice the NTSC button to indicate the type of pulldown flag to include in the encode for DVD BlurRay playback.

    Zoe,

    The others are on the right track, thinking as I was that you can simply encode for Blu-ray and send them that file, and they can then author that to Blu-ray without transcoding again. The screen grab shown was for “MPEG-2 Blu-ray”, but “H.264 Blu-ray” would be recommended to squeeze out maximum quality, is more efficient than MPEG-2.

    Note that this encode will produce two separate files, for audio and video. That is normal for disc authoring software needs. The audio will normally be .wav, but you should be able to switch that to Dolby .ac3 under Audio tab in export settings and that will create a far smaller audio file for emailing, and Encore would later convert to .ac3 anyway, so nothing lost.

    Thanks
