VHS for Lofi Effect - Need Help!! Music Video

Hey - Noobie here. I've been editing our band's music video in fcp7 and everything was shot on a canon t3i dslr. the edit is all finished and im doing some basic coloring right now, but heres the main issue/question:

im trying to go for a lofi vhs glitchy type of feel for the video. some of the plugins like badtv and adding noise look more cheesy than anything else for the most part. i've heard of some people actually converting the fcp digital file into vhs and my buddy has a canpus advc110 converter.

my question is if i convert the file to vhs and then back to digital (possibly multiple times for more distortion), how will it effect the audio quality of the song? if the audio quality is too degraded, would i be able to just use the video and then re-sync it with my audio track digitally, or would capturing the video from vhs back into my computer inherently throw off the frames a lil bit (the key issue is that i wouldn't want our singers mouth moving out of sync to the music)?

If both options are bad (aka digital > vhs > digital either distorts the audio too much or video cannot sync with audio file), what are some options i have to effect the video digitally?

thanks so much in advance.

Yes, I think your best bet is to get it to VHS, and then copy that VHS over several generations. I have never seen a filter or plugin out there that will give you a truly authentic look. You might even want to give your hi rez video a small amount of blur to begin with, even before you put it to tape, perhaps use a chromatic aberration filter also. Today's cameras are just way sharper than the old days, and even after transferring an HD picture to video tape, it may look like too good still. I would experiment to see what you like best.

Once you have sufficiently degraded you video, you should recapture it. Create a new timeline with the degraded video, and then put the original video on top of it and reduce its opacity so you can use it as a reference to see where it may be drifting sync. You may have to go through it on a shot-by-shot basis, and just cut out or repeat frames to get yourself back in sync. Technically, VHS does have timecode on it, but unless you are using proper decks synced to a black-burst generator, you may get some slight drift. My guess is that you're simply going to play it out and hit record on a cheap VCR, so unfortunately you'll probably have to check sync manually. It's a song's length, so it shouldn't take you that long.

Depending on what kind of distortion you are looking for you should try to play with tape back on a VCR with manual tracking. It will be a little wheel or slider and if you mess with that you'll get varying degrees of noise and whatnot.
