HD Uncompressed 10 bits

[Luis]

I have two questions
1 Can I import HD Uncompressed 10 bits files in Combustion? What other options do I have if I have to preserve the original quality?

2 How can Combustion is so unstable since version 1 up to now?, I mean I not really worry about fancy new things for newer versions, it’s just fix something is there since the very first days of this software, stability!.

It really depends on the format and codec just like anything else that has to do with video files.

Each release does get more stable, but your system and hardware drivers also effect the stability of software like Combustion.

So simple like … importing iff files? it crashes sooo much that is practically unusable if You use iff files from maya. I’m using combustion from version 1 (and paint and effect before that) and since version 3 it became so unstable that i almost stop using it.
It’s not question of configurations or drivers, because I used it on sooo many configurations, and it equally unstable on all of them.

Also, talking about 10 bit (HD footage).
How come that combustion can’t read 10 bit footage over wire, from smoke system. It’s sooo lame!!! It can read 8 bits, and that’s it. It ruins, othervise nice smoke&combustion workflow!
I think that they are beating a dead horse here. With this last ‘upgrade’ autodesk is just trying to squeeze litlle more money out of market, before they kill combustion for good.

I got a Quicktime movie Uncompressed 10-bit 4:2:2 HD 1920 X 1080 (1888×1062) Millions. The file was created from a HDCAM tape.

I tried to import the clip in Combustion but all I see is a noisy signal with no image. If I import it in Shake is ok.

And regarding the stability, I agree vizije, I tried Combustion in thousand of different computers and configurations and it’s always the same even you buy the most expensive mac or pc.

… it depends on your codec…. the 10bit blackmagic codec works great here on my pc, as well as 10 bit dpx file sequence….working of a file sequence is better anyway…regarding stability…haven’t had any more problems over the years than with any other software doing music videos and commercials….

Quicktime movie
codec is “Uncompressed 10-bit 4:2:2”
frame size 1920×1080
data rate 132 MB/s
fps 25
Pixel Aspect square

I can’t open it in Combustion, If I reconvert the file using FCP as “Uncompressed 8-bit 4:2:2” then is ok. In Shake, or even Nuke, I can open the 10 bit.
What is even more weird is that if I export the “Uncompressed 10-bit 4:2:2” Quicktime movie as “none” compression (I keep the rest parameters untouch) then I can open it but it has a shift in color, it’s a bite bluish!.

I don’t get it!!.

mhh,ok, the blue-ish tint could have something to do with colorspace conversion. not sure about that. there were quit a long discussion about qt and color shifts somewhere on the internet -don’t remember where, though-
if you absolutely have to use this “Uncompressed 10-bit 4:2:2” codec, why don’t you just use shake or nuke then?! in any other case, use a codec c* can open. or better, use a 10bit dpx sequence, or a 16 bit tiff sequence, if fcp cannot export dxp files. processing will be faster in c* in any way, compared to these yuv codecs.

best,

suggest using a format that works better like DPX or CIN

it may help…

1- Go to Application/Combustion
2- Go to Data directory
3- Backup the Quicktimecodecs.txt file
4- Open the Quicktimecodecs.txt file and remove the [v210] line
5- Save your file
6- Start Combustion and playback your Apple uncompressed 10-bit clip
