Colours for HD Production?

[tingsern]

I am doing a documentary for a Malaysian National Park. It is being edited in HD (1280 x 720). It will be shown on their Park's HQ TV (LCD) after mastered into SD DVD.

I have lots of JPEGs from the Park - pictures of flowers, plants, trees, fishes, etc, etc - that will be incorporated into the HD Video (using EDIUS 4.6.1 Broadcast).

The video was filmed on my HVX202.

Question - Are there any guidelines to fit the JPEGs into the gamut of the HD Video? I am currently cropping the JPEGs to fit the aspect ratio of HD (1280 x 720). Using Photoshop CS3.

Question - Anybody aware of Photoshop plugins to convert the colours in JPEG file to fit the HD Video gamut?

Thank you,
TS

You can use Imaginate 2.0 or Stage Tools to utilize the full quality of the photo, at least in most cases, and manipulate it to achieve the 'ken burns' effect.
Before doing this the photos should be prepared so to reduce 'flicker.'
I use photoshop to prepare said photos.
Photoshop will also set it for NTSC colors.

Are there any "PAL" colours instead of NTSC colours? Or really - does it matter at all today?

[Fred Dwyer]

You may be happier in your editing if you convert those jpg files to tif format. Using JPG compressed images puts quite a load on your CPU. Of course with today's super powerful processors it may be less of a problem than it was in the recent past.

Thanks for the suggestion. But, with a total of 8 cores at 3.2Ghz each - I reckon JPEG decompression will be last thing I will have to worry about :-).

[Fred Dwyer]

Wow! Does EDIUS really use all 8 cores??

Wow! Does EDIUS really use all 8 cores??

I wish that were so!

[tingsern]

I wished that as well. But realistically, it only uses 2 - 3 cores at the most. But - the most important aspect - as long as I get real time response from EDIUS - I don't really bother how many cores it is chewing up ... right?

Anyway, using Imaginate - I can import the IVP files into EDIUS instead of rendering (using Imaginate) to "lowly" SD ... And EDIUS will output in HD instead.

One question for the experts -

If I set 3 keyframes in Imaginate ... 0 seconds, 5 seconds, 7 seconds, I can see the effect clearly when I simulate within Imaginate. Total scene = 7 seconds. Unfortunately, importing the IVP file into EDIUS - EDIUS don't honor the time stated in the IVP file. Any fix available?

[Fred Dwyer]

It's a long time since I've used Imaginate, but I seem to remember that the IVP files can be stretched or compressed on the timeline, just like a titlemotion roll. Lengthen it and everything runs more slowley. Shorten it and you accelerate the action. Do I remember incorrectly?

[GrassValley_BH]

Depends on whether there's audio in the IVP. With audio, you can't lengthen/shorten.

Hi Fred,

Yes, it does. But, what happens if I have 3 keyframes in there? Between 0 and 5 seconds, the "window" pans from left to right, then from 5 seconds to 7.5 seconds, it zooms out?

If I import that IVP file into EDIUS, and I stretch that to 10 seconds, let's say, does EDIUS handles that keyframes timing proportionally? Meaning, 0 - 5 in original becomes 0 - 6.5 (about there) and 5 to 7.5 in original becomes 6.5 to 10?

Thanks.

Hi Brandon,

Ah ... thank you for that information then. So - if I want to lengthen / shorten IVP within EDIUS, I should do that without audio first. It makes perfect sense here.

[Fred Dwyer]

As I noted it's been a long time since I used Imaginate, but I do believe the stretching of time is proportional throughout the clip.
