View Full Version : Maximum Quicktime File size

I'll be using PRO V4.0 and 2 DL1s.

We have someone creating some Quicktime movies for the show.
Max length of any given one will be about 4 minutes.

What are my limitations for the file size of the Movie?

My initial guess would be the drive free space, but I don't want to run into a Catalyst limitation.

there is no " size " limitation .

What kind of Computer do you have and what kind of Hard Disk ?

if someone else doing the files for you, you should keep in mind this :

having a bigger resolution of the video projector it's useless unless you want to zoom in the movie.

Dl1 should be 1024x768 . So if you want to use the entire resolution make the movies 1024x768 .

NOTE you can't play 16 1024x768 Movies on 16 layers it all depends on your catalyst system .

in Term of space it depend on the codec you are using. The developer suggest the use of the follow ( BUT IT ALL DEPEND ON YOUR SYSTEM )

Photojpeg 100% down to 50% ( 100% good quality but you can play less movies at the same time , 50% worst quality but little bit of more layers )

Or you can use the Apple Intermediate CODEC but again it all depend on what you want to do.


It could be easier if you come back with the system profile of your Catalyst computer

This is a rental, so I only know the basics.

It is a G5 and the content is dedicated to a SCSI drive, while the software resides on another drive.

Also, I only plan on playing one movie at a time.

The max length of any movie we make will be less than say 5 or 6 minutes.

I have access to the unit ahead of time, so I plan on having our video creator make me a sample movie at 1024x768 to test with.

4 to 6 movies at the same time should be allright .

there are 1000 options about the codecs

Ask the video creator to make you 1024x768 25 frame per second using photo jpeg 85% .

I promise the quality will be allright. and performances too .

don't worry at all about file size in term of space . you have gigas

Actually Emiliano,

If he's going to be using a G5 instead of a Mac Pro then he should probably use Apple Intermediate Codec (AIC) instead of photoJPG. with Rental gear, this can be an issue.

Use 1024x768 if you need the resolution but we've all done just fine using PAL or NTSC and using the DV codec to render quicktime is the thinnest of all.

Not knowing which SCSI disk you will have in your Catalyst, this is the best solution.

If quality is important then use photoJPG but I would never run more than 4 layers at the same time this way. Also like Emiliano says, keep it below 75%. Even 50% would be fine.

Thanks guys. From what you have provided I believe we are comfortably within the capabilities of the system.

I look forward to playing with Catalyst again.

g5 rental with scsi drive - really need to check out what they can do-

there is a lot of performance variation in this-

You will probably also have to install the AIC codec from somewhere.
Use AIC codec -

6 movies on g5 with scsi is not going to happen.

photojpeg 85% not good either for playback - fine for content creation on PC. convert to AIC on mac.

hang on, AIC it's not pre installed that's why I didn't suggest it.

am I correct ?

You are correct....in order to be able to use AIC you need to have something like iMove HD (included in iLife 08) to have that codec.

Luckily we will only be running one movie at a time.

As for format, I'll be receiving a sample range of what the designer can produce. I will have this several weeks in advance.

The AIC codec is not 'limited' to installing additional software. It is freely available on the web. All you have to do is copy 2 files in to the correct locations... (info also freely available on the web...)

AIC at PAL resolution on a G5 would be sufficient. You dont need to necessarily render at the DL1 native resolution (1024x768) - G5 and SCSI is OLD technology - although can still work with gentle persuasion.

I dont know what your budget is - but its worth getting a quote for an Intel Mac as a backup if plan 'A' doesnt work out for you... Do drop me a line.

Simon you are correct in general , but Chris said he need one movies only and the graphic designer already make a 1024x768 . If he need one layer only a resolution of 1024x768 will be ok . why not using the full resolution of the Dl1 if possible?
( IF ONE LAYER ONLY )

this isnt obvious - neither is the location-

there are also old ppc version

and several download locations- but nothing actually comes up-

True - G5 will probably do this ok - and if you connect to the DL1 via RGBHV, theres no reason why you shouldn't use its native resolution. However, if you distribute from the catalyst to DL1 via SDI or composite, theres little point rendering above PAL (or NTSC)

I am using the same system I have used previously. Output 1 splits to the monitor and to the CIB converter to RGBHV and from there to two DL1's. Outputs 2 goes through a converter to S-Video and feeds into the house projector.

The stock content is 640x480, and looked fine last year. I asked my designer to get me some samples in this size and the generic Quicktime (most universal) format.

I expect this would do for my application. These are background images for a christmas show.
