Unusaually long rendering time in 64 bit vegas pro10e
I have been a user of pro for quite sometime now. I have been using pro 10 (first version, I think “a”) on windows XP and was able to render my AVCHD footages quite successfully using Sony AVCHD template. Typically a hour Video used to take about 6 hours for rendering. Recently, I changed my computer to a Dell desk top machine operating on windows 7, 64 bit OS. I downloaded and installed pro 10e, 64 bit version. Initially I tried rerendering an already saved Vegas project ( from my old version), an hour long video,on this new computer. I found that it did not complete rendering even after 14 hours. Then I thought the problem may be using an old version of the project file. Hence I started a new project, assembled my AVCHD clips to an hour long video and tried rendering this. Initially vegas pro indicated that the expected time was close to 5 hours. I left the machine to render overnight. Before I went to sleep, 50% rendering was completed in 2hrs 30mts and expected time for completion was shown as 3 hours. However in the morning, I noticed that the rendering was still going on even after 14 hours and not even 80% complete and I had to cancel the rendering. Since my new machine is faster (Intel I5 processor) and 64 bit, and has an AMD graphic processor, I was expecting much faster rendering time. Can somebody explain what is happening and what mistake am I making. Has any of the settings be changed? Should I go back to my 32 bit version of 10a? If so from where can I download this version. Unfortunately I have not saved the executable file for 10a. Will the 32 bit version work on 64 bit OS machine?

Give us some more specs about your new machine.
In the meantime check your Dynamic RAM setting under options|video. Set this to a low number during rendering (32 or 64). Check the maximum threads setting too.

Hi Jeff,
Thanks for your quick response. Here are the machine details:
CPU: i5-2320 processor (3.0MHz, 6MB cache)
Memory: 8GB DDR3 SDRAM 1333MHz
Graphic processor: 1GB GDDR5 AMD Radeon HD 6770.
HDD: ITB, 200RPM.
OS: Windows 7 Professional 32/64 bit.I checked the Video preferences. They are as follows:
Dynamic RAM Preview max: 350MB.
Max # of rendering threads: 16Thanks again,

Try reducing your Dynamic RAM Preview max from 350MB to 32MB and render a short project.

Hi Jeff,
I reduced the Dynamic RAM preview max to 0 and the maximum number of threads to 4 and reran the project. Initial estimated time for rendering was 5 hours. After 40 mts, 16% rendering was complete and it showed estimated remaining time as 3hrs and 28mts. CPU usage was 86%. Everything fine till now. However in the morning when I saw, it was still rendering, completed only 28% and taken 8hrs and 28mts. CPU usage was still 86%.
I have tried earlier in this new machine short footages (15mts) and it looks OK. My problem is with long (one hour)video rendering.What is this Dynamic RAM preview? Even when I set it zero, I can still see video on my preview window during rendering.
I am really stuck.
Thanks,

A lot of research about performance has been posed here. Search this forum for “Dynamic RAM” and read te larger posts.
Are you using filters or have an opacity change? Cropping, anything that would require intensive processing for every frame?

I am not using any filters. The same video rendered fine on my old XP machine with 32bit vegas pro 10 (first version). The only change is 64 bit and version 10e running on a better machine.
