To make sure I was up to the task I just got a new computer(Intel core i7 3770 3.4GHz quad core ivy bridge, 1GB AMD HD Radeon 7570 video card, 8 gigs of ram soon to be 16) and a new video capture card, the Avermedia USB HD DVR with built in hardware H.264/MP4 encoder.It works great for dubbing stuff off of my DirecTV DVR.It's like no stress on my system.I can even do other stuff while it's capturing.Now all I have to do is digitize all of my old VHS tapes.The problem is that everytime i've tried so far at some point in the tape it starts to drop frames and video and audio get knocked out of sync.
Now, these tapes are relatively old(maybe about 10 years, or so), but they're in decent shape.I'm also using a regular 4 head Hi-Fi HQ Admiral VCR.This is really frustrating for me.Is there a way to fix this?Is there a way to fix it in editing?I thought maybe I can just adjust the audio and video time lines to sync them back up.Would that work?The card and software outputs the file in TS format and I don't know any good video editing software that works with that format.If anybody can help, i'm all ears.
there is no encoding on a VHS tape.
He's attempting to tell you it's due to macrovision encoding, but it's not. Macrovision just puts extra pulses in the vertical interval, it won't cause dropped frames like you're experienceing.
You mentioned that you recorded thes from a broadcast...therefore they won't/can't have any macrovision encoding in them.
A time base corrector will help you.
Greg lives in a different 'reality'.
Dropped frames and out of sync usually is due to some bottleneck or hardware not catching up quick enough. Why it only happens with VHS but not DVR isn't immediately clear, but I presume DVR is using component video in HD and VHS composite? More scaling to do? And playing VHS itself is OK with no sync problems?
You haven't told us what resolution, frame rate, bit-rate etc. but there's no clear reason to use HD resolution (AVCHD/Blu-ray) for VHS, esp. when you run into some problems. Try plain old mpeg2 (if available) and burn to a DVD and it's much simpler. I can do that on my 10-year old 1.4GHz PC with ATI card, and CPU is only running 60%. Or if you insist, use SD resolution for AVCHD. Have you actually checked what your CPU is doing?
Audiosceptics accept audio trials using 25 people. A recent Oxford study with over 353,000 patient records from 639 separate clinical trials shows for every 1,000 people taking diclofenac or ibuprofen there would be 3 additional heart attacks, 4 more cases of heart failure and 1 death every year.
My CPU isn't doing much of anything.As I mentioned, the card has built in hardware encoding, so it's doing most of the work.
For editing TS files you might wanna try SmartCutter or VideoReDo. Again, check the HDPVR thread, as the users there have to deal with .TS files as well.
For your dropout problem: I had the same when I started digitizing tapes in 2003 or 2004. Back then I used a PMS Sweetspot card for recording. There are s-video decks which have integrated TBCs and we can be had really cheap. I used a Sony SVO-1500P deck for playback without TBC, but ran the signal through a standalone DVD/HDD recorder before going into the PC card. The HDD/DVD recorder didn't record anything, just passing the signal and converting the signal from composite to component.
Go to the forums, you will find many threads about this and what you can/can't do to help the problem.
There are lots of experts on that site experienced with VHS transfer and they can give you the best advice.
I've done it myself. I don't mean to discourage you but oftentimes it is not easy or cheap. (Your best/easiest bet may be a DVD recorder.)
