File Size after Rendering

[Mylenium]

Looks like you are using an uncompressed AVI and in that case filesize is normal. AE does not handle DV in a lossless fashion, so stay away from any experiments and keep your current workflow if you do not want to loose even more quality.

Hey, don’t worry. I’m going to help you.
If you need it to be an AVI file (only if),slect the Microsoft DV Codec.
Now if you really want good quality video and low file size do this…
Select Quick time format and for the compression select Sorenson video 3, at best quality. 30 frames per second and hit OK. Now render it and tell me what you think.

[Mylenium]

Na, that’s no good. Assuming he is adding even a simple transition in Premiere, what you suggest would add yet another compression with all the visual artifacts. It’s simply a matter of quality and quite frankly – if disk space is a concern, go out and get another one. You can get 200 GB SATA disks (which are sufficient for DV) for what? 90 Euros? Ridiculous, considering how easily it solves any issues.

i agree with mylenium. big mistake. use the lossless codec out of afx.

Mylenium, so you always use uncompressed video?
And when all the work is done, how do you keep it?

[Derek Hader]

Disk Space is not a concern… frankly I was just confused as to why/how DV footage from Premiere (whether straight from Digitizing, or an export from a timeline) is a convenient file size, while a seemingly identical file format export from AE is like 10 times larger.

I still don’t understand that.

I work in an environment where sometimes I need to create pieces in AE, then transfer them across our network, or to clients, etc. Also sometimes what I’m making in AE is for a webvideo (https://www.bconvideo.com/vancouver_katereen_events.html) and I don’t need a high quality 3GB file (and the long render time that comes with it).

Other times I’m working on videos for TV or even Broadcast and I want the highest quality.

Just tryin to understand my options and why things are the way they are.

Thank u all for your input!

How are you getting the file out of AE? Export? Render?
What are the settings for export, or in your output module? They can’t be “DV” since DV has a fixed data rate, so your rendered file should be the same file size as the original DV file (for the same running time).

You need to have a better understanding of CODECs and compression and how these affect your workflow.

There are lots of CODECs out there. Each optimized for at least one purpose. There CODECs created for CD-ROM delivery, Web delivery, DVD delivery, editing systems, archival etc.

There are CODECs that compress in a variable manner, ie. more complex images receive more bytes with which to store the data – most CODECs perform variable compression. The DV CODEC compresses at a constant datarate.

A 1-minute DV encoded footage will always be the same size regardless of which application that outputs the DV file.

In your workflow, you should look for ways with which to minimize the number of times that you compress your footage. Each time you compress your footage, you will be losing quality, wating time, and lose more hair!

As for your workflow, I suggest importing (you can also copy and paste your premiere pro timeline into AE) the premiere pro project into AE. This precludes having to compress the video before it gets into AE.

Once in AE, you should render out to the CODEC that your editing system is working in. In your case, it’s DV. So, render out from AE to the DV CODEC.

Skeeter, if you want to compress you work for the web, you should consider taking a look at Sorenson Squeeze https://www.sorensonmedia.com/ it’s very good for this kind of job, I have compressed files from 500Mb to 5Mb, of course there is some loss of quality, but excellent quality for the web.

I hope it helps.

I film with a DVCam and edit in DV, but when ever I have to render I go to a higher codec. I only export to DV rushes that they have not been touched. For example to print back to tape some pics. But try never back to DV. Even to make a DVD y do it from a 8 or 10b Unc depending of what I’ve put and I’ve done in the time-line.
