T2i Transcoding troubles with premiere CS5 and Vegas 9

Vegas has had issues for years with working internally in RGB color space. I don't believe this has changed in version 9 and leads to image degradation. I believe you are essentially handicapped from the beginning by working in Vegas. The 32-bit floating engine in Vegas does not equal Premiere.

Now before anyone accuses me, I am no particular fan of Adobe or Adobe products, I have gripes with Adobe and they have shortcomings just like everyone else.

YES...I am suggesting that the OP at least try using Premiere on native video without any transcoding since he already has CS5. I don't understand why that wouldn't be the first path taken.

BTW, I just discovered that the Premiere CS5 trial does not have the h.264 codec or the DSLR editing presets, so there is no way to try before you buy. That is unfortunate because no one seems to believe the performance is better than expected.

Vegas has had a 32bit float engine for several years, and I've colored at least 4 films using it over that period of time. Vegas 9, released last summer has handled native 5D/7D footage since it's release and I have colored one film shot on a 5D in that time.

Perhaps CS5's 32bit float engine is magically better than Sony's. And perhaps you guys are right.. there is no need to transcode. The original poster asked about CS5 *AND* Vegas. So I will defer to you guys on the CS5 side.. but I absolutely stand by what I've said if he is planning to take his work through Vegas.

Further, if the OP said he is having struggles with this HD footage in it's current DCT based i-frame codec, are you thinking he'll get BETTER performance using highly compressed H.264 on the timeline? Especially since it seems he doesn't have the hardware spec to meet the Mercury Playback engine needs?

Well I GUESS it narrows down to: Editing original file in Premiere CS5 (preferred editor) or slightly laggy editing transcoded DNxHD 145 8 bit footage in Vegas.

It's not that I don't believe you, it's just that all indications are that CS5 is relying HEAVILY on the GPU to get this performance, and nothing the OP has indicated leads me to believe he has a CUDA card installed. Clearly, I could be wrong.
 
Yeah, I have onboard intel gma graphics...
Havent figured out which graphics card to get... I heard that any nvidia with over 768 MB could run CUDA, which would be more than amazing. Im looking for something ~$100

I'm afraid you are going to be quite disappointed. I think the very bottom end of the recommended cards for the Mercury Playback engine will cost you more than 4 times that amount.

Best of luck.

I know that, but there is a hack for using any nvidia card over 768mb, and it works on how many cuda cores your graphics card has..
