This is my first post here as I have spent the last couple years trying to consume the wealth of knowledge on this site.
I, as many have, originally tried digitizing some tapes using one of those terrible, cheap USB adapters. Obviously, the result was terrible. So fast forward to today and I have spent days reading though the posts here and acquiring the correct equipment. I read countless warnings from LordSmurf on several threads to not buy "for parts or not working" TBC-1000's on eBay
. So I went ahead and bought an untested "for parts or not working" TBC-1000 on eBay
. What's life without a bit of risk? It showed up with a 5V power adapter
. I plugged in a correct 12V adapter and it works perfect. My guess is the seller tested it with the 5V adapter and it didn't work so they listed it as for parts or not working. I found a few bad caps on the board so I recapped the entire thing. I also mounted the board on standoffs so that I could connect directly to the TBC-100 card and bypass the distribution amp (see picture). Since I have the (older?) version with linear voltage regulators, noisy power should not be an issue.
I then purchased a JVC SR-VS30 on eBay that apparently would not accept a tape. It showed up and loads tapes just fine
. Cleaned the heads and the picture looks very good.
So my current setup is JVC SR-VS30 -> TBC-1000 -> PCIe ATI TV Wonder 650 -> Virtual dub lossless AVI. All connections are S-video with high quality, double coax cables.
I also have a Samsung SyncMaster 910MP connected to the other video output on the JVC to monitor the output.
I am having a couple problems. The first issue being that the colors in the capture are very muted. I can see a strong difference between the captured file, and the signal on the Samsung monitor. I have also swapped the Samsung for a CRT TV and the result is the same. The signal on the display is much more vibrant than the captured footage. I have also connected the TBC-1000 inline with the monitor to ensure that it was not causing the color issues. It did not seem to have any poor effects. This leaves (I believe) the only suspect to be the capture card. Is this a common problem and is there an easy fix?
The other issue is that I am getting "smearing" in the output file. I have attached two images of the same scene in a movie I am using for testing. I found a reference copy online to compare my capture quality to. One image is a screenshot from the reference copy online, and the other image is a screenshot from my captured file. Obviously the aspect ratio in my captured video is wrong, but I believe this is easily fixed in post processing, right? You can see the smearing quite clearly to the right of everyone's red "ears". The red color also provides a good example of the color muting I am experiencing.
I have also attached a small uncompressed clip of my captured file, since I have seen that as a common request in other threads.
If the problem is in fact the capture card, I have two other options on hand:
- ATI All-in-Wonder Radeon 7200 32M AGP. I do not have a computer with an AGP slot with enough processing power to prevent dropped frames. If this is a good card, I can try and find a better computer with an AGP slot to try it.
- Hauppauge WinTV PVR-500 PCI. This card does not seem to have any way to output uncompressed video other than some strange YUV format which I could not view or import into any other software after capture.
Another note, even when viewing the captured video in VLC player with de-interlacing enabled, the interlacing is still extremely visible. This can be seen very easily in blinking eyes in the video clip. I am not sure how to go about solving this.
If anyone has any insight into any or all of these problems, it would be greatly appreciated.
