PNG sequence issues
Good morning
As I have mentioned in a previous post am creating animations which were created using the Quicktime animation codec. Because Of issues I am having with the animation software I wanted to try sequenced PNG.
My project settings are based on my video camera (1080i 29.97 Sony HDR FX-1)
When I import the Animation codec version I get 29.97 smooth playback in the preview window in Vegas. When I play the PNG version in the same Session, preview stutters and I get like 15 – 20 frames in preview. I am playing both off the same drive (Internal SATA) CPU use is low for both 8% for animation codec, 14 % for png. i7 2600,3.3 GHZ, 8 gig ram,
Any Ideas?
P.S., My camera is interlaced, my Animation is progressive, does it matter what my Project settings are? Animation is 1920X1080, Camera is 1440×1080?
Thank You

The sequenced PNG version on the timeline is not actually a codec implementation. Vegas just strings together the images by itself. In theory this should not be a bottleneck but the way the program works the editor prefers to get its data from the API through a codec (and preferably a codec that it is optimized for like certain Quicktime ones.) When it has to do resizing of PNG images instead of video to fit on a timeline things start to slow down a bit. There is not a real solution to this except possibly a proxy… but I am not exactly sure if the media bin “replace” function can actually replace a clip with an image sequence. If it can you can edit the Quicktime animation and later replace it in the media bin with the sequence and all of your changes will remain in the timeline.

I just did a test to see if an image sequence is a valid replacement option and it is. You can edit your Quicktime version of your animation and have the smooth playback you want then right before you render replace it with the better looking image sequence version.
