View Full Version : 3 questions about making a Demo-reel: Best Resolution / Framespeed / Video-codec?
08-25-2005, 12:01 PM
I'm about to set up my 3D-scenes for rendering a demo-reel.
It's only meant to be in digital format, not on VHS or something.
Now I don't know much at all about this stuff (I normally mostly do stills).
1:What resolution should I render in?
3:What video-codec should I use?
Anything else I need to know?

well, im working for one to put onto DVD, from there im gonna compress it. but this is where i start.
I have been rocking
720 X 486
29.97 fps (or 30 if ya wanna be lazy!)
Sorenson 3, quicktime goodness.
thats what i like, im sure others have their different prefs.
other things to remember
watch your music... make sure its not insane and overpowering, just nice and complementing

Good tips, and questions not often asked!
Is there a stickied thread on what should and shouldn't be in reels? Cause I've heard employers hate robots cause of all the ones they've received over the years, but I wanna use one for my animation! :shrug: And I'd like an oppurtunity to talk about it.

I'd recommend using full d1 square pixels for resolution, ie 720x540 at 30 fps. I also like quicktime for a codec because everyone can view it, but getting the best compression out of it sometimes troublesome. Alternatively you can use DivX (AVI codec), its also very popular
Squash-n-Stretch, do a search here in the general discussion forum. There was two very long threads concerning this and would be very informative to catch up on.

Judging from a quick peek at your web pages, you're Swedish, right? PAL standard for you, then.
So, for a DVD or a VHS, I'd recommend 768X576. Squeeze it into 720X576 in the editing/compositing program you're using. And use 25 fr per second.
Unless you're jobhunting in countries that use NTSC standard, of course.
I'd recommend Quicktime too, because if they use Macs, anything else is painful, and if not, they can always get the player. But Quicktime is a format, not a codec. Sorenson 3 is oft touted as good.
But if you're for instance making a DVD, then that's a whole new can of worms there.

Okay, first a few things need to be clarified:
You say "digital", but do you mean for the web? On DVD? CD-ROM? Those are all digital formats. For that matter, so is HD, DV, etc.
As for my answers, I'm going to limit myself to US companies (for both you if you're applying somewhere there, as well as for anyone else applying in the US). Also, for now, I'm going to avoid all web-based discussion. For most companies I've worked with, I would avoid having your reel ONLY on a website.
So, having said that, 29.97 is probably the best frame rate that you want to render at. That's the frame rate for all standard definition (in other words, NOT HD) formats in the US. You could render at 23.98 and add 3:2 pulldown to make sure it works on both SD and HD formats, but that might be too much for now . . .
If it's going on a DVD (this part is also for RobW720--we sat across from each other at the CGTalk lunch at SIGGRAPH), it will be in the MPEG-2 codec. You could render individual frames as tiffs or targas and then let an editing program prepare it for DVD output, or you could render as another lossless format before converting. You probably don't want to use the Sorenson 3 codec if you're going to DVD because it is a lossy codec and you'll lose quality before you convert to a DVD. However, I *guess* if it's going to be on the web, Sorenson 3 would be okay . . .
To answer JasonA, since I'm a purist when it comes to the stuff, I disagree in rendering in square pixels at 720x540. If it's going to be in a .9 aspect ratio in the end, render it as such. Also, DivX isn't very common on a lot of HR computer's (the people reviewing your reels), so I would also advise against that as well.
If anybody needs further clarification (or if I didn't explain something very well), let me know, and I'll try to add some more info.

Do yourself a favor and back up the uncompressed AVI file of your demo before putting it on DVD.
Im having a difficult time converting my DVD reel back to an uncompressed file so I can add new footage to it. Partly cause I dont have a vid capture card.

Be aware that many studios will want your reel on VHS. This is for 2 reasons: firstly because you can guarantee the framerate that the movie will play back at which you can't for Quicktimes or AVIs on a CD and secondly because even now you can't be sure that a burned DVD will work on all players. I am transitioning to doing both VHS and DVD and I will still be getting tapes made for some time to come I think.
There is a sticky thead (http://forums.cgsociety.org/showthread.php?t=69427) at the top of this forum on showreel etiquette which has much good information.

Loads of thanks guys for aiding me in finishing my reel!
Intentionally I planned to store it only as a file to be either e-mailed or viewed on the web, but I guess I may as well set it up for DVD as well then.
Very good advice and guys, I really apriciate it.
