> I want to produce and archive all my own personal footage to Hard Disk using the best reasonable format.
Ummm. Leave it alone in the format you acquired/shot it at.
Howard, thanks but the key word above was "reasonalbe"!
Besides, I want to use Premeire to edit and cut it the way I like!
Preserving the original source footage from camera is reasonable.
Premiere is simply not designed to edit compressed files... and does not do well when forced
Copy your DV AVI Type 2 files to an external USB hard drive when your edit is complete
I understand that its not designed, or indeed any video package, to EDIT compressed footage, however, maybe I'm splitting hairs here, but I wish to edit and THEN compress to Divx/MPeg. Not edit already compressed footage.
> but I wish to edit and THEN compress to Divx/MPeg
Your final product or all your source material?
Premiere has the notion of Importers & Compilers. We have default ones that allow interaction with AVIs and QT movies; it's also possible to write custom ones (for example, Matrox, AJA, BlackMagic, BlueFish are 3rd party companies that provide their own for the formats they support).
DivX doesn't provide a custom plugin for Premiere, so it falls on Premiere's default AVI compiler plugin to do the work. This plugin will work with any codec that is exposed by your OS via the Video for Windows API, so if you install DivX, presumably it's adding their codecs to that list. That's why it's available. It'll also be limited by the usual Video for Windows limitations, ie you won't be able to handle / create media beyond a filesize of a gig.
Now, whether it works? You probably need to talk to other users (the point of this thread), or to DivX directly. Mind you, you haven't specifically spelled out what's not working for you. Care to elaborate?
If one needs to go beyond Wil's stated limitations of Video for Windows, it would seem that the Export of an uncompressed AVI, which would then be taken into DivX-Pro, could be encoded with their compression presets. IIRC, one needs to upgrade to the "Pro" version of DivX to be able to do this, but it appears to just be a drag-n-drop onto their (DivX) Converter. Other than the ~US$40 investment and then the time to output to AVI, then convert to DivX, it seems like a simple solution. Until DivX provides Adobe with the plug-in, I do not see another way, unless I missed something big.
Thanks for clearing that up regarding Divx - its certainly what I've found to date, however I just find it odd that a (free) Divx/Mpeg Plugin doesnt exist?
Having cleared that up, what I am trying to achieve is the following...
Use APP to capture HD footage from my Sony HDV camcorder (HDR-HC3)
Chop and change the video, using APP editing features, title, effects etc.
Then when happy with the final article, export the finished work to a video format that allows me to maintain the original HD quality on the hard disk. The idea being that with this footage, I can discard/overwrite the HD recorded tape and have the option to further convert the HD video to Divx/WMV/DV PAL/YouTube etc.
Also, when Bluray/HDVideo becomes more widestream have the option to burn out to this format while maintaing as best quality as possible.
Hope that makes sense?
On another note, at the moment I am getting some odd numbers back, perhaps you maybe able to shed some light...
A 10min capture from the HD camcorder is being stored at 1440x1080 on the Hard disk with only 2GB in a native/raw format.
But when I export using APP, Microsofr AVI, no compression the file size shoots up to 25+GB??
Thanks in advance for any further help!
> I can discard/overwrite the HD recorded tape
Do not ever do that.
> But when I export using APP, Microsofr AVI, no compression the file size shoots up to 25+GB??
Uncompressed AVI are big that is normal.
You must understand your camera compresses the image to a ratio of (I think) 15:1... It is highly compressed!
What I dont understand then is if the camera compresses the footage down to 15:1 then what is happening that causes the file to increase to 25-30GB when its saved as an MS AVI uncompressed?
Of course I know saving as an uncompressed file will do exactly that - save it uncompressed, but at what point is it uncompressed to reach that final size? Is APP uncompressing the "original" 15:1 compressed version into the APP editor first?
I'm bugged with same trouble for months, so I'll share what I've come out with.
Always grab from hd cam with HDVSplit (perfect little program, that even splits files according to scenes) - that is also your perfect backup
Edit in APP3 and encode to Wmv if you want to be finished quickly
Edit in APP3 and export to tape (have to have HDcam connected and than disconnect it and rename file *.hdv2 from (capture folder) then you have your final movie in original hdv format (m2t) which you can nicely encode to xvid with avidemux or mencoder and quality is great and size is small.
So far I couldn't find a way to do full divx encode. Dr. DivX doesn't do m2t neither Convert Divx, DivX author can only do DVDquality DivX export. Virtualdub can not read mpeg2 (m2t) files, neither Virtualdubmpeg, neither Nandub.
>then what is happening that causes the file to increase to 25-30GB when its saved as an MS AVI
Your going from compressed to uncompressed and you cant' understand why the file gets bigger?
You can make soup from a chicken, but you cant make a chicken from soup.
cant tell if youre trying to be sarcastic or not, but I'll explain my comment...
As I'm sure you know once a program compresses anything, (bitmap/video frame etc) identical information is discarded which in turn results in the compression and subsequently a smaller file.
What I was questioning is where all this extra data is coming from when the file once its ported to the PC from the camcorder and then to APP?
Da_mENIZ - thanks for the info - I'm trying this out right now!
Thanks everyone for info!

To give you a vastly over simplified example of why uncompressed is larger observe the following:
A simple "run length encoding" scheme will store data in the following format: "4a6b5c", while uncompressed it would be "aaaabbbbbbccccc". Effectively, the same information is displayed when viewed (decoded), but the compression scheme uses less disk space to store the data.
Note carefully that this simple description doesn't even touch on lossy compression schemes.

In a lossy format, the "aaaabbbbbbccccc" would be something like "a1a2a3a4b1b2b3b4b5b6c1c2c3c4c5" (presented as something like "4a6b5c +placement code") in the first frame of a series of frames, the next frame would for example be a1a2b3b4c5 (presented as something like "2a2b1c + nothing else (=0)") because the other a's, b's and c's have not changed (thinks the encoder) since the prior frame.
Quite clear right?
>The idea being that with this footage, I can discard/overwrite the HD recorded tape
Bad idea. Never record over or get rid of original footage. So, with that shift of viewpoint in mind, do you still need help?
Its easy to store away the HD tapes from my camera, however, as I'll be upgrading to the new Sony HDV camera with the 100GB hard drive over the next few months, its inevitable that I will need to overwrite the "original" footage that was on the HD. Am just trying to find that ideal method now of storing the footage long term on my HD.
Ive found from using the HDV split program to capture and store the footage as m2t files is ideal.
>Am just trying to find that ideal method now of storing the footage long term on my HD.
Whatever any guru says, but I doubt any(ANY)one stores uncompressed AVI as backup, as it unreasonably huge.
m2t are perfect from my point of view, as you don't loose anything from the camera anyway.
Postedit backup, can basically stays in same format (with m2t sources, titles,..) or you do hdv export and you endup with hdv m2t again which I think is again very close to original quality.
I know this isn't a proper forum, but I finally tried Vegas yesterday, and it just worked flawlessly (interface isn't as funky as APP3) export dvd,mp2,h.264,xvid,divx.. and divX really showed beautiful quality with 2 pass encoding with 50MB/min from original ~200MB (m2t). + (big one) you can render on network (up to 3 computers with 1 license). Now that's usefull, doing your NLE on laptop and have office computers do render.
Wish adobe would copy that aproach :)
> Now that's usefull, doing your NLE on laptop and have office computers do render.
I have been advocating this render farm capability for ages it seems and filed official feature requests. It gets time Adobe implements it IMO.
