4k to HD resolution issue

Hi all

got a somewhat weird issue going on here.

I work on a high rez photoshop project, which I imported to separate tracks. The originals are roughly 4000x7000 pixels large, so I set the project to 4k.

I zoom in to full screen, as it's a poster and I need to have fullscreen vertical pan. All still looks crisp and well on my monitor, but as soon as I render to HD ( H264 14mb/s template) , the result is muddy and looks like blown up. I never had the issue that it actually looks good on the timeline but worse in the render. Shouldn't it actually be the opposite, really?

1: timeline snapshot 2: render snapshot

Any idea what I'm missing?

Thanks!

Is your render quality set to "Best"? This setting mainly affects scaling quality.

Also I would double the data rate for rendering or even use Voukoder as renderer (with CR rate set not higher then about 20).

Hi Marco

wow! Voukouder is so much crisper, it's impressive! Thanks a lot for the tip!

I first tried the Vegas H264 CBR at 20mb/s, not really any improvement. Same thing with Voukouder - great!

I actually never saw that much of a difference - must be because it's a high rez drawing project this time.

Another suggestion. Resize your image in Photoshop "before" importing to Vegas. You should take into account any "zoom in" factor that you might want to apply on the timeline in deciding upon the resized dimensions.
