Ok, so then the recompression situation is actually happening here.
the AE rendered file is not actually uncompressed data, it is an uncompressed version of the original mpeg2 compression.
In order for you to have clean export with progressive material you need to be in a progressive sequence in PPro.
If the DV preset used is interlaced then you export the sequence as progressive it will deinterlace it = loss of half the resolution. Then there is the render with preview files. If this is ticked then you will be using the DV compressed renders to then compress to whatever your export settings are going to.
If you are rendering out to Quicktime with the codec set to Animation 100% you will end up with a large file but not real gain in video quality. MPEG2 export from this will incur a quality hit, that is just mathematics of compression, and recompression. MPEG compressed to MPEG (generation) will always incur in loss of quality.
Can you upload a couple of still frame screen grabs for out comparison. If it is as simple as making a new seq in desktop mode, which i feel it will need to be, then copying and pasting the edit into it you should be home free.
Let us see the results it will help us to pin point the actual problem. 🙂

Hi Eric, can you verify the term RAW. It’s not used in video. Uncompressed is commonly used but I’m not sure that what you mean. RAW is a format used in photography terms for uncompressed photos.
A raw 23.976 progressive fps render from AE which was itself originally a 29.97fps mpeg2 video from DVD which I painstakingly reconstructed in AE with reverse pulldown.
Did you rebuild an AE project based on an mpeg video as your reference? Or did you convert the mpeg video itself from 29.97 to 23.976?
What resolutions are your AE comps, clips and ppro sequences?
Cheers,
Jon Barrie 🙂Jon Barrie

Hi Marc,
one of the most commonly Mis-understood aspects of compression has to do with recompresion.
if a video starts from DVD mepg2 and is then edited, it must be recompressed upon export as the group of pictures properties (GOP) has been altered in the process of editing. The chance that the GOP will line up with the export GOP settings is near impossible.
This kind of compressing something compressed, (generation) will result in poorer quality exports.
Converting the mpeg2 to uncompressed before exporting to mpeg2 again won’t make it any better at the export stage.
I hope this clarifies your results.
Respectfuly,
Jon Barrie 😉Jon Barrie

Hi Jason,
You can have both CS4 and CS5 installed on the same system. no need to uninstall CS4. CS5 and my Canon 550D (T2i) is such a magical experience. Enjoy.

Are you exporting via the render queue in AE? There is a drop down listing for uncompressed with alpha. Start with that.
Also, the millions+ colourspace won’t show If the compressor/codec is not compatible with it. Must have the right codec first, png, animation, as last post. Then the millions colors + will be available.

You will need a certified mercury engine card. Check the adobe site for the current listing.

DV is very poor at maintaining color edges in reds, I wouldn’t trust the way it looks on Quicktime either. QT will always show DV files in a soft low quality. If you have QTPro you can manually change the setting (Ctl/Cmd+J) for video to highest, but then you need to save it like that to keep it just for that video.
If your video is for web – export to H.264 at square pixel ratio.
If your video is for DVD – export it to MPEG-2 DVD at Highest Preset Settings.

I just tested the “theory” out and found a set of single frames with the lock set to the speed and duration with a duration set to 15 made the speed 6.6% (PAL 25fps video file) with the Ripple Edit ticked made all my single frames sit for 15 frames no movement to the next frame. At 6.6% there is still room to move for longer frame length with just the single frame.
Let me know 🙂

From what I undertand the 285 can’t maintain the bandwidth over an extended period as the 3800 can. Which equals more RT layers with the 3800.
Technically specs only look good on paper. Functionality justifies the price.Jon Barrie

Go along and cut the clip only where you wantto jeep that frame. So you have lots of little clips where the in point is the frame u want to keep. Do this all the way along.
Select all and hit ctl(cmd)+r for speed duration. Uncheck the link and set length to 1 frame. Check the ripple option and press ok.
Kablam! Try to do this on fcp. It can’t.
If u need the frames to hold longer than 1 frame in length select all and set the length with the lock checked to your desired length. Make sure ripple I checked. Hit ok.
Kablam!
