Bouncing, scan lines, video at bottom during VHS playback?
3 Attachment(s)
I would just like to preface this by saying how thankful I am to the VHS / restoration forums and community (many from DigitalFAQ!), for the level of diligence and extensive details which have greatly eased me into the shallow end of what could otherwise have been a misstep into deep water.
For better or worse, I've roped myself into the process of archiving the family tapes, and whilst I have managed to get several results that I'm happy with so far, there are a few issues across some recordings that I would be grateful to check to see if anything can be done to rectify, or at least somewhat improve, on the digitising process going forward. Please see below for the attached video samples and a brief description of the issues in each clip. They have been compressed in order to be uploaded, so excuse any blocky image quality as the problems should still be identifiable.
Below is the equipment currently in use:
I did dabbled a bit with the 'AviSynth' software trying to remedy these issues, but I currently lack the knowledge of what filters to use as have only managed to make each example clip look worse. Unfortunately, my budget and access to purchase more optimal hardware / software will likely be somewhat limited (I probably could, at most for now, spend a hundred or so extra for this task if it would lead to an improved outcome). I would probably just be satisfied to know if any of these elements are in my control or not, as most of these tapes are 20+- years of age and weren't in the best physical condition when they were passed onto me. Pointers to any equipment in different price ranges would be much appreciated, if extra equipment is needed. So whilst I am prepared to be advised that a new VHS player or full field TBC will solve most of these issues, and would appreciate this as 'peace-of-mind' confirmation, for me personally doing this as a personal family project, I am unlikely to actually spend high-hundreds or thousands for a fabled high-end TBC or VHS, and would accept some problematic clips over a financial decision that could take a few years off my life expectancy! Apologies if this is a bit of an essay, and thank you in advance for any suggestions. |
Example 1 and 3 looks like they were either recorded on a misaligned vcr or the HS1000 is misaligned (but in that case the tapes should play fine in another vcr and even commercial recordings could have issues.) 2 might be too but maybe a bit less. If there is something important on the tapes, and it's the recording that is misaligned rather than the NV-HS1000 the "optimal" solution is to intentionally misalign a vcr to match them and use something like a panasonic dvd-recorder for stabilization (unless you want to screw with alignment and risk breaking a very expensive vcr.)

A good external TBC will improve the green/purple line issue in Example 1.
The wobbling in Example 3 is fixed by turning the VCR's TBC off and using a Panasonic ES-10 or ES-15 as an external TBC. |
Cannot look at sample now, but the title describes format mismatch as well (ie, PAL input, trying to record NTSC, etc)

Thank you all for your responses so far, please see for added information below:

If I make any further progress, either by finding another player for me to play around with or purchasing an ES-10, I shall try to remember to post back here with some more example clips and any differences or (hopefully) improvements that the extra equipment has made. Thanks again! |
Samples 1 & 3 are most likely miss aligned recordings, you can get a cheap VCR and miss align it, Sample 2 is timing issue, a DVD recorder like the ES10/15 should be able to stablize it.
