Thanks a lot for the speedy response.

My main confusion really comes from the relationship between DPI and the physical size of the document.

Say my photograph was 8×12 inches at 240DPI, if I wanted it to be 8x12inches at 300DPI I would have to resample. Is resampling going to reduce the quality of the print?

Say someone wanted to print my image – would they ask for it with specific dimensions or do they just work with what they’re given?

Thanks again.

Awesome, massive thanks to both of you!

I swapped all the camera lens blurs for fast blurs and it seemed to be rendering much quicker when I left it. This time it should be done when I get back to it tomorrow morning!

Thanks Vince.

I’ve decided to try rendering out using CBR, which is really about the only change I’ve made after doing a bit of Googling. Maximum render quality was already unchecked :/

Media Encoder still reckons the first 30 second file will take about an hour. Each file only has a maximum of 11 photographs, and the only effect I can think that might be causing some issues is Camera Lens Blur (I’ve used it a number of times on several different adjustment layers). Other than that it’s just scale, rotate, position and opacity.

I’ve just started to render the final files out now, so I can only hope it’s done by tomorrow morning!!

Thanks again.

Okay, I’ve just discovered that when the original footage is put into Premiere and rendered in the main timeline, it plays fine. No ugly distortion/pixels/warping – so that should hopefully save me from having to convert all the original files.

What confuses me now is… the original footage dimensions are 1440×1080, and when I put that into a 1920×1080 sequence it fits fine.

But when I export it as 1440×1080 it comes out as 4:3, and when I export it as 1920×1080 there is some letterboxing (top and bottom).

If I set the sequence up to be 1440×1080, it’s also 4:3. I don’t understand how the original footage can possibly be 1440×1080 yet it fits into a 1920×1080 sequence and appears to be 16:9 when playing with QuickTime?

Thanks a lot again!

If it helps, here is what Premiere says about each clip.

The original clip:

The re-exported clip:

Identical, yet Premiere seems to show one at 16:9, and one at 4:3?

[Jonnie Lewis]

Thanks again.

In Media Encoder, I set the pixel aspect ratio to square pixels (1.0) and I matched all the export settings to be identical to the original file (frame rate – 25fps, dimensions – 1440×1080, progressive) and tried again. This resulted in no letterboxing in QuickTime and it looks the same as the original file – great.

However when I put it into Premiere it seems to be 4:3. Comparing the original file to my freshly exported file in the Project panel, the original says 1440×1080 (1.333) and the new file says 1440×1080 (1.0).

If I use Media Encoder to export a 1440×1080 1.333 file, the result comes out with huge letterboxes down each side.

I’m really confused now. If I set Premiere’s sequence settings to be 1440×1080, everything looks 4:3, but when I play the original 1440×1080 file, it looks 16:9?

Many thanks again.

I’m currently trying things out with CS5, but I’ll be using CS6 at work.

I downloaded that codec pack, and re-encoded the video. When you said “pick MOV as your container”, I picked QuickTime from the Format drop down menu – is that what you meant?

Anyway I did that, and threw it back into Premiere when it was done. I didn’t see any of the horrible artifacts I was seeing before, though it’s 3 times the size of the original file and is a bit jerky/jumpy when being played in Premiere’s source window, although it plays fine when it has been rendered in a sequence.

There is also some letterboxing which I don’t quite understand, as I set the dimensions to be the same as the source file, and the re-encoded file is about 3 times the size as well..!

Does that help shed any more light?

Thanks again Angelo.

[Jonnie Lewis]

Hi Angelo,

Apologies, I thought I’d been quite clear.

Basically they have given me an edited video in the format of a H.264 .mov.

When I place that into Premiere, there are all kinds of artifacts – quite hard to describe, but like large blocks of pixels and warping.

It plays and looks fine outside of Premiere, so it must be something Premiere is doing to it.

Any ideas if there’s anything I can do?

Many thanks in advance.

[Jonnie Lewis]

Great, thank you!

[Jonnie Lewis]

Thanks for that! It was frustrating me not knowing why some videos were like that and some weren’t!
