RRS or Marvel for VCD creation

[IM_Riktar]

Trying to find the best method to convert Mjpegs to Mpeg1 (VCD) files and cleaning out the closet (I found my original Mystique 220/Rainbow Runner) has left me with a question,,,,

As was pointed out in an earlier post by Doc Mordrid the old RRS package had the ability to lower the compression rate of captured Mjpegs through some value changing in the registry. The only limit (As I recall) was based on your CPU/Harddrive speed. That was back in the days of AMD K6-233's being the norm. By todays standards The CPU/Speed issue should be non-existent. Unfortunately this wonderful little gem can't be applied to the Marvel Gx00 cards. At least not to the extent it could on the original RRS cards.

Since I have enough parts to throw together another computer I was wondering if I would see any benefits to capturing through the RRS card at a lower compression (maybe 2 or 3:1) compared to 6.6:1 on my G400 Marvel. Or should I pour my efforts into increasing the speed of my existing system such as to be able to capture at a rate of 25 megs/sec for uncompressed conversion to Mpeg1?

The old RRS was a pretty good card alright.

When it comes to the tweaking of the MJPeg quality this technique has been surpassed.

With a fast machine (600-800mhz) you can pipe the YUY output of the Marvel to the PICVideo codec, which can capture at 5 mB/sec. The RRS could only be tweaked to 4-4.5 mB/s tops.

YUY2 captures are also useful and require about 21 mB/s. Two Maxtor ATA66's on a Fasttrak66 would handle this, and RGB, with little difficulty.
