Sony vegas pro 12 has unstable rendering with CUDA and OpenCL.

[Steve Rhoden]

I render fraps videos from an sata 2.0 samsung spinpoint f3 to an OCZ Agility 3 120gb with 520/500 read/write.
That there maybe your problem. Have you ever used Vegas before to
complete a render with those same specs?

Are you really trying to render video at 128bit per color channel or am I misreading that on your screen? 1920x1080x128

Is there an option to do something more reasonable for color depth like 12bit?

[anders salvesen] “2x grx 680 4gb”

Is that meant to be an NVIDIA GTX 680? If so, that’s your problem. Vegas doesn’t yet support the GTX 600 series (Kepler) GPU’s.

Yes, i used to have vegas pro 11, and used to get 6-10 fps with the same render settings as i allways use with only cpu usage cause it did not support the gtx 600 series to render with.

[Anders Salvesen]

It doesnt support 600 series? And still they are at 40 and 60& on both gpu’s when i render wither with cuda or openCL woth no error messages at all like vegas pro 11 would?

[Anders Salvesen]

I saw it now, i have allways rendered at åixel format: 32bit floating point (full range) cause of a youtube video i saw once to have the best quality possible at smallest space taken in my videos since i record gameplay and render fraps videos for youtube, but no matter with my old i5.760 1gen cpu or my new i7-3770k cpu i would allways only have 6-10 fps.. And i dont know why i allways had that poor fps even with 80% cpu.

[Anders Salvesen]

It went much faster with the dept of only 32 aka 8bit ^^

Don’t believe everything you see on YouTube because most of it is wrong. 32-bit is only for people working with 10-bit YUV video which you are not. You should be using 8bit. That’s why it’s the default!

The default setting is 8-bit just because it requires a weak hardware to work.
Believe me if you guys tried to improve the scenes by adding several Video FXs, such as color corrector, 32-bit works more perfectly than 8 bit because the former one contains more data after calculation.
If you guys still do not believe, then try to import an MPEG clip and render it as WMV. Then you will see how 32 full range works more perfectly than the 8 bit!

[Rick Qi] “That’s really shit if compared by Adobe’s.”

Hey Rick, if you think Adobe is so great, why are you even using Vegas? I moved from Adobe and Avid liquid because it was so unstable, to the point I could not deliver a project or more than 1 occasion. Vegas has never failed me once, and I have done 100’s of projects. Yes, it does occasionally crash, but show me software that doesn’t.

[Rick Qi] “The default setting is 8-bit just because it requires a weak hardware to work.”

As John said, 32-bit is only for people working with 10-bit YUV video which you are not. You should be using 8 bit. This is good advice from a professional who has been working in the business for many years.
