I don't want to leave you with nothing, so here it goes. These kinds of things may be possible to improve if you clean the tape and the vhs heads with something similar to isotope alcohol. A professional can do this and may be able to fix the lines with a fresh transfer (if it was S-VHS, instead of VHS) but this won't work if you got a bad VHS copy from a missing S-VHS master. I noticed they flicker on and off, so you essentially have good data in there, hiding in the odd field. you may be able to paste it into the even field. you can lay out the video (if it is 29.97 fps interlaced) into a 59.94 frame composition and then every field will become a frame, so you may be able to use a simple clone stamp tool. painstaking? yes, but may be possible. you may be able to repair and merge automatically with frame interpolation (which uses vector data) I used to enhance vhs detail by frame merging fields this way with timewarp set to 50% inside a comp speed 50% which produced the same speed but interpolated missing data. I believe Topaz does something similar. If you wanted something quick and dirty, you may be able to simply key out the brighter streak, and overlay a duplicate video with a 1 frame offset or solid black matte. at least it wouldn't be as flickery. now, if the lines are unrecoverable, you may be able to do some jiggery pokery in post. how much is questionable at best, but if you have time and nothing to lose, try these: 1. after effects with Effects > Blur & Sharpen > Camera-Shake Deblur (will only use good frames) 2. clone stamp every other frame for every line. maybe a high end scratch removal tool used for film restoration may work? 3. any content aware AI algorithm, see photoshop batch processing images content aware 4. topaz enhance 5. any high end film restoration software like resolve, pfclean, diamant-film, phoenix, drs nova etc. 6. There's very few free automatic solutions out there such as: spotremoverfilter dot com or infognition dot com/dirtcleaner side note: it will be important to capture the video again with full interlaced fields, then deinterlace with topaz or some other motion estimation tool qtgmc etc. if you capture a single field, you are in effect, capturing half the resolution.
