Problems Exporting
I’m working on the biggest project I’ve had to do to date which is a promotional video for a camp and I just finished the 22min 11sec video and I went to export it out of Premiere CS3 into Encore CS3 and the transition worked flawlessly but the quality of all of the moving images in the video are shot. Here’s an example.
I’ve read about losing an entire field which is kind of what this looks like to me but not only am I not sure whether or not that is correct but I also have no idea how to remedy the situation and I need to ASAP.
Here’s what I’m working with:
Sony Vaio VGN-A150
2G RAM
250G Hard Drive (internal)
but the project is located on a 1T external drive.Export Settings:
NTSC, 720×480
29.97 drop frame [fps]
Lower
Quality 5.0
48 kHz
16 bit
PCM
VBR, 1 Pass, Min 1.50, Target 4.00, Max 7.00 [Mbps]Granted I’m not quite sure what half of this means but I’m wondering if I should use CBR. I’ve read that constant should be used for short videos and I wasn’t sure if 20+ min was considered short.
If anyone can help with settings or can simply recommend a preset that works well, that will be greatly appreciated.

You are working with interlaced footage, it’s as simple as that.
That’s the way it will look on a computer, but it will look fine on a TV set.
No way around it unless you either:
Shoot progressive to start with, or de-interlace (and lose half your resolution in the process).
Regarding your settings:
If your DVD contains less than 1 hour of footage, choose custom and pick 8 Mbps CBR.
For anything over 1 hour, Google “bit rate calculator”, and use the recommended settings. Stick with 2 pass VBR.

Another opinion 😉
I generally stick with CBR encoding, especially for shorter programs. I have seen players stutter on playback with the up and down encoding rates (spikes) on DVD-R, keeping it steady seems better.
Also, some players can have playback issues with high data rates on burned media. I’d use 7.0 CBR as a maximum, the viewer will not see a difference between 7 or 8 quality.
The purpose of VBR, or Variable Bit Rate, is to maximize the efficiency of the encoding for long programs, finding the best compromise between quality and available space on the disc by allocating a higher bitrate for complex scenes and a lower bitrate for simpler scenes. For a short program where ALL the video can easily be encoded at a high setting uniformly, I don’t see the advantage of VBR.
I prefer consistent quality when the space is available. For longer programs, the formula of 560/minutes will tell you the encoding rate, for instance 560/90=6.2, round down to 6.0 and you have overhead for menus and such. Formula assumed Dolby audio encoding.

My son is using premiere pro in school and at home. He has a 1/2 hour school documentary that he cannot get out of the computer. he has used this progrma for a few months with no problem exporting to avi then making a dvd. When he tries to select export to tape it won’t grant that selection. It wont let you select it. I tried to connect a firewre and t oplay it out to a deck as if previewing it but no luck. Any advice?
