RT Effects Playback, Multiple file format Playback and SD DVI AVI offline for Premiere Pro 1.5.1

[Paul Cameron]

Just to add

The DV AVI is a compressed file format, 1/10th to that of SD uncompressed

You can edit it in either Adobe Premiere Pro DV editing mode or in Bluefish444 editing mode.
The difference being that in the BF edit mode , when you export it will conform to V210,

I find it interesting that a company that charges that much for their stuff would be that imprecise with their propaganda…

If we’re looking at sheer bandwidth, DV is around 3.65 MB/s and uncompressed 8 bit SD is about 21 MB/s or 10 bit is around 24 MB/s. Even if you don’t take the audio portion of the DV file into account, you’re still talking about an 8:1 ratio max with 10 bit uncompressed SD…

I don’t see anything about V210…I know about Sun Servers that have a V210 designation, or wireless content…what do you mean in this context?

Hi Tim

here are some values for you for PAL 720 X 576 I @ 50 (25 fps) uncompressed no audio
RGB 10 bit is 41.57 MB per second
RGBA 8 bit is also 41.57 MB per second
RGB 8 bit is 31.10 MB per second
V210 ( 10 bit YUV is 27.65 MB Per second

NTSC is slightly higher in some modes
Add audio, in this case a stereo pair embedded in the file is gets a little higher.

If you disagree with this I am quite happy to give you the formula to calculate these values if you wish?

When you capture an uncompressed clip via premier pro with v210 10 bit yuv (via the Bluefish444 card) and capture a clip of exact duration in the DV AVI capture mode, the clip is 1/10th give or take or a ratio of 1:10

If 1:8 makes you happy then fine, that is still a very good compression rate for a solution to capture from an uncompressed SD card either via 10/12 bit analog or SDI source.

If you wish I am quite happy to loan you a card and you can find out for your self and publish what every results you find.

Just let me know and I can put you in contact with our representatives in your region.

All the best.

Axio is claiming 4 layers of 10bit SD plus 6 layers of graphics in real time for $7500. How does Bluefish compare price and performance wise?

Hi Paul,

…I still don’t understand exactly what “v210” is…is that your own codec?

An example of the math I’ve been most exposed to is here:

https://www.drastictech.com/wp_compression.html

…about half way down, the CCIR 601 uncompressed PAL figure comes out to be about 20 MB/s…which is what I’m used to seeing. Of course, it’s based on a 4:2:2 Y/R-Y/B-Y, 8 bit,”uncompressed” signal (undersampled…but uncompressed).

When I think of DV’s compression ratio…I think in terms of acquisition…and standard digital acquisition is 8 bit. Obviously using 10 bit colorspace as your starting point increases the “uncompressed” filesize..is that what we can attribute the datarate difference between my math assumptions and your figures?

If you find any bad assumptions in the math on the linked page…I’d like to expand on that so I understand it…I won’t need a card today, thanks.

🙂

V210 is a pixel format from Apple or from a 3rd party
It is a 10 bit YUV color space file format that is uncompressed.

Final Cut Pro for example understands this codec natively, we added it to Premiere Pro for the cross platform support.

Hi Shane

What we have done with Premiere is more or less the following;
