Ironically just last night at home I made a ProResHQ file using QTPro 7 and I checked the bottom size choice for 1920x1080 which yields 1920x1080 (1888 x 1062). I use this all the time at work. When the file was done and I ama linked back to check it in Avid there was a border all around which I assume is the 1888 x 1062 is somehow overriding the ama link. I've never seen that before. I went back and checked the top 1920x1080 size preset choice and all was fine. I do this all the time and don't see the border on my Avid SNDX Ver 5.5.4 at work I just checked and all the files I've delivered at work show 1920x1080 (1888 x 1062) and there have been no problems.
Ironically today I'm reading delivery specs regarding removing the CLAP atom from a ProResHQ 422 file and it seems it's dealing with the same issue. There is a JES Intensifier free software. This appears to be dealing the display aspect vs. the actual size of the file. I've never dealt with this before but I would think as long as I choose the upper 1920 x 1080 it should be okay. It seems to me they are concerned with the movie properties showing a slightly smaller display size vs. normal size. If both normal size and display size match at 1920x1080 I would think I'm sending a correct file. Can anyone shed some light on this new parameter.
I remember that this was sort of the QT equivalent of the CRT K factor IIRC where the edges of the picture are cropped a bit which would hide some blanking issues etc... Am I correct that the display size is in essence cropping the picture in QT to avoid edge of the frame anomalies etc...
I've been delivering ProResHQ 422 files with the 1920x1080 (1888 x 1062) setting and I haven't had any QC issues or rejections from this. Is this because of iTunes delivery specs that this network is repurposing the content on? Is an iTunes delivery effected by the 1920x1080 (1888 x 1062) more so than other digital deliveries?
