I'm trying to export a 2 hour video clip I recorded with EyeTV (but as stated, this really applies to any file format), and I'm trying to export it into iMovie, for simple editing, then into iDVD for burning.

The file format that's being used to export is DV.

But the file size is HUGE. I believe around 25gb (3.4MB/second).


Since the end result will just be on a DVD (4.4GB) .... what would be the best way to accomplish this? As in, how should I export from EyeTV? (so I'm able to do simple editing in iMovie then burn with iDVD) ... without taking up that much initial exporting space!!!!

with iMovie you will have to edit in DV footage. There is no way around it. You can import it as something else but you will have it converted when you import. For the project you are looking at you will need a minimum of 35 gigs of free harddrive space. You will also wind up using 4+ gig for your finished DVD

[badtz]

normally, when you have a DV camcorder.... would you need this much space [30+gigs] when you're importing 2 hrs. of footage?

[brianb]

yes dv footage is about 13 gigs per hour. 3.4megs per second x 60 seconds x 60 minutes roughly every gig is 5minutes be thankfull your not using uncompressed which is 50 seconds per gig

[brianb]

what format is uncompressed? [curious]

[brianb]

uncompressed is uncompressed true 601 video. Raw data no comprsion what so ever. DV is compressed most HD is compressed mpeg is compressed. Uncompressed is uncompressed I don't really know what else to say

[badtz]

when movies film in digital format, do they film it uncompressed?

[brianb]

generally no. Star wars episode 2 was shot in a compressed HD. Compressed isn't bad a little compression goes along way. for instance your DV (DV25mbit) is a great format for consumers and profesionals alike. then you have DV50/ Digibeta (roughly equivelant) Which is a great standard that alot of broadcast stations are migrating too. You get twice the Color data but lose half the tape time you can use. Then there are the billion flavors of HD out there

Generally speaking wether you are using Standard Def. (what you have) or High Def you wind up shooting in a compressed format because the amount of Data that you can shoot on any given tape is so small at the Uncompressed level. Uncompressed is more used in the compsiting of movies where you don't want to ruin colors or black levels or avoiding artifacts by compressing to much

I have heard of a huge Hard Drive raid solution that can be brought in the field to record Uncompressed but you are talking terabytes to record a few minutes

great explanation! Exactly what I was looking for

...... do companies compress it back down after compositing in uncompressed usually?

In what professional situations would one use DV25? is miniDV 25mbit/sec.?

[brianb]

MiniDV is DV25 the diffrence between your camera and a pro camera besides the size is the number of chips in the image processing you have one CCD where pro cameras have 3 CCD

And generally no they don't recompress the movie back down because it will be transfered to Film for viewing at your local Movie Theater

EyeTV records in mpg / mpeg2 format which can be burned directly to DVD. The whole point of using EyeTV to capture video is to avoid using DV and encoding to mpeg2 (because mpeg2 encoding can take FOREVER). I believe EyeTV comes with a basic editor to take out commercials and trim the beginning and end, *maybe* joining, but no transitions or special effects.
If you plan to do lots of editing with your captures, I suggest getting something that captures in DV format.
If you're dead set on converting your mpg to DV and back again, keep in mind that there's no way to avoid some loss in quality. With that said, there are a few ways to do it. Mpeg Streamclip (check versiontracker) will export mpg to DV. BBdemux will seperate the audio / video streams, from there you can convert the video in Quicktime and the audio in iTunes. Mpeg2works will do what you need as well. If you can afford cleaner, it's terribly horribly slooooow, but will do an excellent job converting.

I'm actually trying to get the mpeg-1 clip from EyeTV onto a DVD.

If I export in DV, the space it takes up is HUGE for a 2 hr. clip [20+ gb]..... which bites since my end medium is DVD [4.4gb]

[cnelson87]

ah, perfect!
If you have Toast you can just drop it into the video tab. If the mpg is too big for a 700mb VCD (or xVCD, a VCD with out of spec bitrate) then it will need to be a DVD. If DVD then the audio will need to be upsampled from 44.1 to 48. I think Toast will do that automagically. Also, it isn't widely known, but the crappy wavy blue menu background in Toast is EASILY changeable if you have Photoshop. I found the instructions in the FAQ on Roxios site.
OK, don't have Toast, try Sizzle, freeware DVD authoring app can be found on versiontracker. You may need to upsample the audio manually.

Does iDVD use 48khz sampling rate for audio? or is it variable?

Is there anyway to import the mpeg-1 from eyeTV into iDVD [for menu composing] w/out having to export it out of eyeTV as a DV file [which takes up 20+ gigs] ..... ?

when you import video footage from a miniDV camera, does it really take up THAT much space when you import it into iMovie for editing?

[cnelson87]

48. 48 is standard for DVD.

no. iDVD only accepts DV. which is really really stupid that you can't import a perfect dvd compatible mpeg. stupid Apple says you have to pay $500 for DVDSP if ya wanna use already encoded mpeg files. DVD authoring on a Mac is still pretty limited, imo. iDVD is crippled, DVDSP is $500, Toast hardly qualifies as an authoring app, sizzle is pretty limited, and Captydv is only available oem. I think that covers it.

yup. DV is big, but at least it aint as big as uncompressed.

I would have to say that DVD authoring for $500 is an amazing bargain. You realize the base code for what is now DVD Studio Pro was not more than 3-4 years ago Software that sold for more than $10,000. Apple has made a huge leap in the pricing of DVD and Video editing Software. Look at the package of the Pro Video Tools FCP,DVDSP, and Motion $1300. For what it is it is exteremly cheap.

And as far as iApps. They are made for a consumer level experience where the people using them wouldn't know what a 2 pass VBR at 6.5mbits does compared to a 4mbit Single pass CBR. Consumers are buying DV. Capture Edit and in one pass make a DVD. It is supposed to be simple so that the moms and dads of this world can make a Video of Jr's soccer game to send the family

badtz: what menu composing do you really need to do?

cnelson: iDVD also accepts any mov file for encoding (at least any I've tried, certainly not just DV codec'd)

Holy F'in sh** I need to play with iDVD a bit more with this latest version. I am able to playback and work with mpg1 and sorenson3 video in iDVD


Batz if you are making MPG1 clips try moving them to your Users folder/Movies and then open iDVD do they show up if you open the customize panel and then click the Media tab?? they just did for me when I tested out the previous persons post


This is all new to me since I haven't used iDVD since version 2

[brianb]

little more testing on my part it looks like muxed mpg1 video will not be usable in iDVD my first test was with a Video only track and that worked fine but it didn't allow a muxed MPG1 also it was a no go with MPG4 video as well

48Khz is standard for DVD? I thought DVD's can range up to 192Khz?

[cnelson87]

to clarify: 48 is min standard. 48, 96, and 192 are all standards as well.

also, what brianb said about iDVD and mpg1 was very interesting. if your mpg is mpg1, then you can demux it with bbdemux into seperate audio and video streams. upsample the audio to 48khz aif with iTunes. both audio and video streams should import into iDVD. i think...
