Large megapixel stills in video

Weldon wrote on 2/26/2013, 7:17 PM

Hello,
I have been editing with VP for a few year now and have never added a high megapixel image to the timeline until today and it was like I hit a brick wall...really slowed it down. The images are around 14 megapixels. I tried to create a proxy, using VP12, but it did not allow that option. I am sure there is a better way. I have 8 gig of RAM and have no problems editing 1080i with plenty of fx. I see so many videos/timelapse done with DSLR's and RAW or high megapixels. I can't imagine how you would use vegas and work with 10,000 stills. What am I missing?

I think images are uncompressed and held in memory. The compressed size of images is therefore irrelevant. It is the number of pixels that matters.

Weldon,

I have to revise my remarks. As stated I am using Movie Studio 12 (MS12). Everything works smooth there. Greased lightning.

I downloaded the trail of Vegas Pro (VP12) and loaded my MS12 project into that. VP12 is a steaming pile of you know what compared to MS12. Interesting since they should be the same code base.

VP12 is horribly slow compared to MS12 on this project.
12MP stills. Project is 1440x1080.

Video preview quality is HORRIBLE compared to MS12. You need best in VP12 to come close to MS12 preview level quality. I cant describe how bad VP12 looks in comparison to MS12.

VP12 cannot preview smoothly. Not even close. MS12 is smooth as silk. My preview is normally auto which normally gives quarter res.

MS12 works with CPU only setting very smoothly, with some stutter on fast zooms. With GPU everything smooth as silk even at set at half quality except on fast zooms at half quality.

VP12 crashes with GPU while edit/preview, unlike MS12.
Note: MS12 will crash on a render with GPU on this project only. Editing 100% stable.
GPU does not help VP12 become smooth in preview.

...depressed. thought VP12 would be an "upgrade", not a downgrade.

For the sake of image / video quality what if I first render the pics as mxf / 4:2:2 / 50 mbps and then re-render from this video whatever I need?

There is another new thread in this forum that might suggest that chroma subsampling may be causing Vegas issues.

So processing big jpegs to change the chroma subsample may be the workaround to use.
