how large should I render? 720x540?

[gaggle]

It's "Standard Operating Procedure" to use a non-destructive-compressing format to render to. JPEG destructivly compresses, so does AVI, so the artifacts the JPEG produces will themselves get AVI-produced artifacts. Might as well avoid double-artifacts yeah?

You can save to Targa, or BMP, or TIFF, doesn't really matter unless we go into the useage of Alpha channels. For that matter you can output directly to AVI if you want, if that's all you'd be doing in Premiere..
You can enable a non-destructive compression on Targas, which reduces filesize considerably. Not to JPEG standards, but still better than several-megabytes-per-frame TIFFs :)

As for the resolution to render to, well standard PAL would be 720*576, with a pixelaspect of 1.3333 (I'm european, hence me defaulting to suggesting PAL, your milage will vary if you're in an NTSC area). You should set the pixel-aspect to 1 if you plan to output to computermonitors, which means, as you suggest yourself, a resolution of 720*540.

720*540 would, at least as far as I'm concerned, be considered a high-resolution videofile on computers. You can go into 320x240 for low-res versions. Lower than that and I'd start questioning if an animated gif wouldn't basically be as useable :)

Gaggle;
thank you very much! I was confuse as when I compare JPEG with full quality to a 16 Bit Targa, I can't see any different.
Lets said I have render all the sequence to targa, and I call them into Premiere, what codec and format should I choose, to make the movie small in size with reasonable quality ?
By the way sorry if this is not proper place to discuss such issue.

Who is going to view your AVI? Are you putting it on the net, or on a CD to send to a client/prospective employer? If size vs quality is your only concern I'd say go with DivX every time, but if compatibility is an issue that won't be such a good idea.

I will output the video for a presenatation actually, as my assignment, and in CD format.
I had a bad experience on how after I add the audio to the video file, output from Premiere, and the playback become "jerky".
I guess that is not an issue for DIVX.

if this is something that you want to show off (to co-workers, clients, corporations, ect.) stay away from avi. it should be done in .mov. i know macs kinda, well, suck. but quicktime has the best picture quality and is the industry standard for film and tv. if your in america of japan, the res should be 720x480. if you plan on putting it on the web, then go with DivX. but for a vcd or vhs then do it in mov.

or, if you really wanna do it in vcd or even dvd, then render out with mpeg 2. mpeg 2 is used on all dvd's. but, if your gonna do vcd, you might as well beef it up to an svcd.

I am showing the video as my final year project, well, kind of importand for me.
Can anyone tell me the parameter I should watch out during the video rendering to any output mentioned above, such as compression ratio, sound sampling, etc.. ?

[sakuramboo]

if this is your final, id crank everything up. where are you located. does your tv run in a PAL or NTSC format? if you live in america or japan, then render out at 720x480 using quicktime compression. when you bring it into premiere, select DV-NTSC. audio should be 44mhz or greater. render everything with quicktime.

[Dave Black]

Just a minor correction, gaggle.

Not all formats of .avi are destructive. You can create an full-framed lossless uncompressed .avi file.

Not all AVI formats are compression based. There are uncompressed formats that exists within AVIs. The only disadvantage of rendering to avi is lack of dropped frame correction. As for quaility you can get perfectoutput from avi.

DV Output is 720x480 and so it depends on your output... Note that NTSC has different pixel sizes then onscreen so you should do some tests... BTW are we talking PAL or NTSC here?
