HELP! How do you get great compression results?

I used scene file 6 (24p advanced) and am exporting a 39mb file for the web. I assume from my readings I do not need to deinterlace my footage. What settings using the media encoder are best for exporting for computer and web use? The footage looks great on my computer when I watch it on microsoft media player, but looks muggy (not crisp, but slightly blurred) when watched on myspace using their flash settings.

What would be best for export to dvd to be watched on tv? Would I have to burn 2 copies with different settings? One for progressive tvs and one for regular crt/tube tvs?

Thank you for your help it is most appreciated!

What is the TRT of the project? If you are limited in the size of the resultant file, then you might want to experiment with the output size vs. the data rate to maximize the quality. There are no single settings that will guarantee the best results as the nature of the source material will effect the compressibility of the project.

No you don't need two copies of the DVD. If you build your MPEG stream with a 12 frame GOP the DVD player will add in the repeated frames (the flagged ones) to generate a NTSC compliant stream. This has the advantage of allowing you to push the data rate up by and still stay under the limits of the DVD specification by not wasting bandwidth encoding redundant frames. If you have access to a DVD authoring program, then export your project from the Media Encoder as a non-multiplexed one and do the Dolby Digital conversion outside of Premiere. The data rate for the video can be CBR or VBR (VBR 2 pass being the best choice for longer TRTs) and can safely be set as high as 8 Mb/s.

To be honest I don't know much about compression, so it may be hard for me to articulate my answers. First off I don't know what TRT means, but the following info may help.

The file needs to be no larger than 200mb for the site it is created for, but I've been trying to keep it at/under 100mb so I can put it on various locations on the net (myspace, utube, etc). For DVD it doesn't matter as long as it doesn't excede 4.7gb.

The project is 5 min long w/ music. At the current settings (suggested by another poster here: 1024 ntsc 320x240) it is 39.5mb.

My settings are as follows...
windows media
1024 ntsc
audio: 96kbps 44khz stereo vbr
compressed: 2 pass, audiences:1, avg 1000...
video codec: windows media video 9
FPS 24 (shot on scene file 6 on a dvx100a)
437.53 ks/sec

I hope this info helps.

Thank you for this info. Per my readings in my adobe book would MPEG2 be best for the web and MPEG2-DVD best for dvds?

Also, my footage isn't coming up in the output window of the media encoder. Is there a way to fix this? I don't know how to activate it, so I've been burning dvds and uploading to the web to watch and see the results. It's a pain staking process without the output window working. There isn't a scroll/scrub bar or footage....


Thanks again!

I compressed a copy of my 5 min short using the MPEG2-DVD setting. It yielded 4 files (one of the video, one of the audio, and 2 others). I tried to get my burner (Roxio) to burn the footage, but it wouldn't recognize the .M2V formate of the video portion of the file. Any suggestions?
 
It's because you didn't enable Multiplexing in the DVD option. Doing so will give you a regular MPEG 2 file with audio.

Thx I had no clue multiplexing existed. Info on it wasn't listed in my book. Now I have a new problem.....


Well I used the MPEG2-DVD setting with Multiplix and the visuals turned out normal, but the audio was messed up. I'm not sure what whet wrong. After 10 hours of attempts with good audio and bad video, I got good video with bad audio. Its hard to explain the audio, but it sounds like there is signal interferrance. Like a cell phone near a computer when it is playing audio. Does that make sense?

Settings:
MPEG2-DVD
720 x 480
689.87 kb/sec
29.97 non-drop frame

Any suggestions?
 
Do a screen cap of your audio settings in the Media Encoder and post it up. Shouldn't be too hard to see where you went wrong.

Do you have access to a real DVD authoring program like Encore?

Correction; the audio sounds like static, which is subtle during quiet moments, but intensifies with the characters are talking and when the music kicks in.

Thank you for any help you can provide!!!

Per suggestion from another fellow filmmaker on another message board I tried making an ISO file and then burning it using my burner program. It worked like a charm!!!!!

thx for all the help and suggestions guys!
