It is possible to sync TN1’s restauration with the GOUT near losslessly by only reencoding a few frames around the cutting points. This is not trivial on the technical side though (the way H264 compresses videos is the reason for it), and therefore only a few video editors are able to do this so called “Smart Encoding” without issues. SmartCutter is probably the best one.
Not sure if Smart Encoding is similar but there are few enough frames missing that I wonder if something like (in premiere) rate extending for a very short duration before or after the missing frames and enabling frame blending for that extended portion would work.
I’ve had decent luck with that technique for other purposes. It wouldn’t be ideal or frame accurate (for those very short portions) but anything should be less jarring than blank or repeated frames. May give it a shot once v1.5 is out. But it’s still great that there’s a fix for people who need or want an alternate dub right now.
