JPEG sizes within VP8

CorTed wrote on 1/4/2008, 2:16 PM

Many of my videos use a lot of JPEG pictures.
I know that VP8 has its share of problems (crashing etc.) if the JPEG is too big. As many cameras tout larger pictures it seems each year the actual filesize of the pictures seems to get bigger. I know there are many (freebie) programs out there that re-size pics, but I like to minimize the various programs running to get the job done, and I was wondering if Sony could incorporate some sort of picture re-sizer within the Vegas environment that would easily scale down pictures on the time line to the appropriate size to keep the problems to a minimum.

I stay out of trouble by using only 2200 x 2200 jpgs (5 meg) with HDV or DV projects and most of the time about 480 x 720 (550) The 2200 x 2200 allows for a comfortable zoom, maybe about 5 or 6 to 1 without a lot of pixelation. Large jpgs will choke Vegas until it stops and screams help. Best way is to render them to avi, put the avi on the timeline in place of the stills then delete the stills from the project. Vegas will then do about 300 mph in the quarter.

Thanks for the reply JJK. I think that is actually a pretty cool idea to render the JPEGs to AVI then place them back on the timeline.
I will surely try that as an alternative.
My original post was more towards the folks at Sony, and is based on many people having crash issues with larger JPEGs and I think it would be nice to be able to manipulate them once trown on the timeline, without any addiitional steps ie. render out, or use an external foto re-sizing program. Just a thought.....

I have never had Vegas crash due to using a lot of very large images. I have, however, had Vegas slow to a crawl when it has run out of physical RAM and had to start using the pagefile. Regardless of the compression ratio of the JPG images, Vegas has to fully decompress the images and keep them in RAM in order to work with them. This is probably an area where the 64-bit version of Vegas (along with a LOT of RAM) will come in handy.

By the way, you really don't want to crop your images to 720x480 for NTSC. 720x528 will keep the proper aspect ratio.

The best / fastest batch converter for putting a bunch of stills into Vegas (or the web, for that matter) is a freeware program called Irfanview. It does a bunch of other cool stuff too like batch scanning and file conversions.
