Video of stills – render quality issue
I have 170 stills shot with a 10MP Sony camera that I want to form a sequence with.
So far, I have converted the pictures to .tiff format. Then I have scaled them using Photoshop CS to different sizes:
– 720×480 (1.0 pixel ratio)
– 720×480 (0.9 pixel ratio)
– 720×534 (1.0 pixel ratio)My project is NTSC DV (0.9 pixel ratio) thus 720×480.
With all the dimensions that I listed, I’m unable to get the proper quality out of the rendered sequence.
>> In Premiere Pro 1.5, the preview with high quality is blurry and you can see alot of jaggies on the edges of various objects in the picture.
>> After having rendered the video, in Windows Media Player, it’s blurry and again jaggies make an appearence.
>> In Encore 1.5, previewing the asset on the timeline, shows blurry and jaggies as well.I have also unchecked the box “optimize stills”.
However, the stills viewed in Photoshop look crips and clean. What am I doing wrong or is this something that I should expect since I’m going from pictures to NTSC video?

Sounds like you are seeing the effects of viewing interlaced video on a progressive scan device – the computer monitor. What does the DVD look like on a TV set?

Hrm… never thought of putting it to DVD and looking at the quality. I do wonder how regular DVDs look so sharp and clear on the computer and the still sequence wouldn’t look the same.
I’ve worked with miniDV footage before and that looked sharp and clear on the computer. Just puzzled at the fact that stills wouldn’t be of the same quality.

I decided to build a DVD to see how it looked on the TV. I looked as crappy as it did on the computer.
I redid my images, resized them to 720×480 and imported them into Premiere. Premiere indicates to me that the pixel ratio is 0.9, but I’m sure it’s 1.0 since it’s coming from a straight resize in Photoshop CS (I left them as is, I didn’t “Intepret footage”). I unchecked the box “optimize stills” and now it looks relatively good on the computer and on the rendered movie.
The only negative is the pixelation during the cross disolve that was added between stills when I did “automate to sequence”. Once the effect is done, the picture is sharp without any jaggies. But once the cross disolve starts, the still is pixelated again.

I figured it out. I used the DV settings as a starting point. The settings that I changed:
Editing Mode: Video for Windows – I believe that this is what solved it
Fields: No fields (Progressive Scan)Now the stills are crisp and sharp. It looked really nice on TV too. It makes for a massive export though. Optimizing the stills makes the files a little smaller however.
Recap:
– I converted the .jpg to .tif (Photoshop CS)
– I resized the pictures to 720×480 (Photoshop)
– I imported into Premiere Pro (did not interpret the footage)
– Automate to sequence
– Export with no compression
– Make DVD with Encore
– Burn and you’re done 🙂Thanks to all

Hi,
You can also try using a Targa (TGA) file
