Render Time is KILLING ME… Premiere Pro CS3

[Phocas Kroon]

Video is 72 pixels/inch also at TV news broadcast. If you use 300 pixels/inch in the timeline for stills it will be rendered to 72 pixels/inch.
Render time of 72 pixels/inch stills in project framesize will save a lot of render time. And don’t worry about clarity of the text. It will be OK.
If you have separate pixtures for the document details, exporting frame from the timeline is not necessary.

By the way, if you want to make a frame from the timeline from one particulary track and you have f.e. two tracks at that location you have to switch off the other track temporary.

Ahah! That is what I was wondering. I was curious if my images were being scaled down anyway and therefore I was not gaining anything by using such large file sizes.

I downsized some of the images in my timeline to 720×480 and to my surprise they seem to look alright in the preview window. I’m going to finish up a small portion and export out the work area to see how the finished product looks.

Thanks,
Jim

Ah, people, people.
DPI is not relevant to video. To be more precise, it is MEANINGLESS in video. Video deals with raster sizes, and a 720×480 pixel image is the same whether you save it as “300 DPI” or “72 DPI”.
Here’s why: put the image on a 9″ monitor. How big is it? How many “dpi” does it have? Put it on a 72″ monitor. Same questions…

DPI is for print. Ignore it for video. Keep track of your image size in pixels.

The reason a “300 dpi” image looks better is that it typically has more pixels. If you are still not convinced, change it to “72 dpi” WITHOUT changing the pixel dimensions (don’t resample). Compare the two: they are the same image, until you _print_ them.

(rant off: it’s just a pet peeve).

Use the smallest stills (in pixel dimensions) you can for the project, that will help. Ideally, resize them in PShop, and don’t do any scaling in Premiere.

Jeff,

I am a bit more of a beginner at using Premiere Pro 2.0. I have done several picture videos for friends and church and they have all turned out great.

My question is related to the post about rendering time. First, I did not realize that 72dpi are to be used in video. All this time I have been using 300dpi and my rendering time and processing time lasts about 3 hours for an average 10 minute video. If I want to make a DVD to be played on a DVD player with a widescreen, using mostly stills that have motion and music, which preset should I be using for my project? I do not understand the difference between all of the choices.

I usually edit my photos in Adobe Photoshop. What image size and resolution should my photos be saved as?

Thank you for your help. I have taught myself how to use the program, so everything I know is from trial and error as well as getting around the technical jargon in the manual. I appreciate your advice and time!

Sincerely,
Lynda Caswell

Well, just like Jeff mentioned, ignore DPI altogether… It’s not the measurement you need to concern yourself with. If you’re editing images in photoshop for a standard DVD, make them 720×480 pixels (Photoshop has a preset for this in the new file dialog under the ‘film and video’ category). If you’re moving the pictures around in Premiere (zooms and pans), make the image a little bigger (1024×768 perhaps) to give yourself some extra room to work with. And, again, ignore DPI. If you’re scanning pictures, scan them at whatever resolution you want and then crop/resize down to 720×480 or so.

Jim,

I think your initial thoughts on dumping the JPEGS (perennially a problem for PPro in larger numbers and sizes) and going with pre-sized and cropped PSDs are the ticket. JPEGS just take a LOT of torque to decode and when they’r humungous, PPro will end up rendering the entire image buffer, which is much larger than the actual video frame, for each image.

I’d try the pre-sized PSD route.
