if you could guide us through the steps you taking to upscale that would help a lot.
If you export your videos as MP4 (H264 or H265), would that work?
By this statement I assume you select your Upscale option of Interlace and Dione:TV (or DV)?
This is required for Interlaced source videos. to get detailed info on your video you can use the free tool “MediaInfo”, it will also tool you the frames/fps.
if the above settings doesn’t workout for you {Dione:TV (or DV)}, try those two methods below.
You also might want to give @TomaszW presets a shot (in combination of one of the two methods below - It can’t be used on interlaced source, you must de-interlace those to progressive scan 1st - the methods below show you how as well ). it might workout for you better.
