Hello,
My company has a lot of older junkets on Beta SP and DVCAM that we are looking to digitize and hopefully sell to Getty.
Getty says it would prefer to keep the footage as close to native quality as possible, which means keeping it standard definition and not up-rezing it.
I am digitizing the tapes into a 30i NTSC (as that is the only SD option with Media Composer) project and capturing at 1:1 MXF, so the captured footage is 29.97i. Getty's specs ask for a Quicktime with a format of H.264, 720x486, Interlace or Progressive for SD material.
I then export the footage trying to use settings that will keep the resultant file as close to the original as possible. I have attached an image of my export settings as a reference. Clearly, the settings are for the exporting of an interlace file because there are options for the file field order. However, whenever I export the H.264 Quicktime the resulting file is always Progressive and not Interlace, no matter what settings I change. I have confirmed this by checking the Quicktimes in the MediaInfo application and by bringing them back into Media Composer.
I've double checked and the raw captured footage is definitely interlaced and I've done nothing with it to alter that fact. I thought perhaps that what I was seeing was wrong so I brought the Quicktimes into Adobe Premiere and Media Encoder and they also saw the files as Progressive.
I then exported a same as source Quicktime of the footage out of Media Composer and it was Interlace. I took this Quicktime to Adobe Media Encoder to transcode it to an interlace H.264 Quicktime and Media Encoder also then converted the interlace, same as source Quicktime into a progressive H.264.
Am I missing something? I've looked around online and there's no information regarding this matter. Is a limitation of the H.264 codec that it can't be SD and interlace at the same time?
I would try to make do with the progressive H.264 Quicktimes but there's some noticeable jitteriness to these Quicktimes so they don't look quite as good as the original interlace footage.
I would greatly appreciate any assistance anyone could provide on this matter.
Thank you.
