That video dropout across the middle can't be repaired. There is no intermittent or otherwise "clean" data that can be used to interpolate new data for new frames.
Don't capture analog VHS as uncompressed. It eats up too much CPU. it's more efficient to capture as YUY2 with lossless
huffyuv compression than to capture as uncompressed. Also, why are you upscaling SD source to HD? It identitfies the video as having been made by a newcomer who doesn't understand how artificial it looks to upscale SD source to HD frame sizes. High
definition is based on high source
resolution, not on big frame sizes. Your sample is blurred with indistinct detail because of the poor upscaling. Your TV or media player can do a much cleaner job of it. The deinterlace interpolations look very soft, and by discarding frames you threw away 50% of your original temporal resolution. You should also be aware that 1920x1080 at 29.97fps progressive cannot be used for BluRay.
But they're your videos, do what you want.
