Okay, got the DV tapes today

Okay for anyone who doesn't know, I was asking if there would be a big difference between SVHS and MiniDV when it came to music videos I was getting from Def Jam records.

Well first off, the picture quality is a lot better as most assumed. However I noticed reds are bloomy like CRAZY. I expected a little color difference, but their skin colors are almost completely different than when i watch the SVHS ones. Their skin looks way more orange.

Finally, I think for some stupid reason they MAY have recorded this in LP mode. I think this because the entire run of music videos is only 54 minutes, but when I take the tape out and look at it, it looks like there's a decent amount of time left. I was wondering if I am correct in my assuming this, and was wondering what effect it has on picture quality. If it's simply a bitrate difference, it doesn't matter since the videos look great in that aspect. However if color takes a hit, it may be my "blooming red" explination. Wondering if there's a way to check if it was in LP mode, and if it is I feel like calling and complaining since the video was only 54 minutes long.

The color thing isn't a huge issue because I can always correct it in vegas, but I was wondering everyone's take on what I just said.

Thanks!

Most decks and cameras will show on the display either SP or LP when you put a tape in and press Play.

When i play tapes in my MiniDV camcorder it will display either "SP" or "LP" on the LCD viewfinder. I would assume that a standalone deck would probably display this on the front panel somewhere too.

There is not difference in bitrate between the two speeds. You get *exactly* the same video information no matter which speed was used. The only problem you might encounter with LP is that there could be more dropouts. However, the video you do capture successfully will be identical from either speed.

DV is compressed with a 4:1:1 colorspace. The reds are sampled with only half the resolution of the other detail. This can cause red areas to look more pixellated or even bleed slightly. This may be what you are seeing.

If you've really got blooming on the reds then you will not be able to correct that out. If it's just that the reds are a bit high in level then yes you can grade that out, but if they've overloaded the A/D during the conversion then info has been lost.

What kind of lights was it filmed under?

What filter is it again where I can adjust JUST the reds? It wasn't color correction or something. I just wanna put the reds down a bit. Like kill the saturation in the reds but leave the other colors be.

I am very surprised that the reds bloom more in the miniDV tape than in the first tapes you were given. I suspect they went through a different process and are a generation or two older.

Just a guess--good luck.

I think the filter you are looking is Color Curves. BillyBoy has a good tutorial on his site.
