64mulford Posted August 6, 2014 Share Posted August 6, 2014 Hi everyone, Just in the process of editing my first TVC advertising spot. I have just got the specs sent to me and they make sense but i do have one question. I need to submit as "1920x1080 PAL 50i upper/top field dominant". Ad was filmed on GH4 in 96, 50 and 4K 25fps. Have edited in FCPX in a 4K, 25p timeline. I figure I'll just send to compressor and export out as a 1080 interlaced clip like is required but I started thinking, is this the best way for highest quality? Should I have just made a 1080i timeline from the beginning? Any tips would be appreciated. Quote Link to comment Share on other sites More sharing options...
Luke Mason Posted August 6, 2014 Share Posted August 6, 2014 Doesn't make any difference, both will get your 4K footage downscaled to 1080. Quote Link to comment Share on other sites More sharing options...
hmcindie Posted August 6, 2014 Share Posted August 6, 2014 Don't do an interlaced timeline. Programs will usually interpret that as actually being interlaced (duh) and they will try using different algorithms while scaling, thereby reducing the quality as the software first deinterlaces, scales and then re-interlaces. They may usually introduce interlacing lines into effects etc. Just do everything progressive first and in the end, flag the file as interlaced.
