Premiere pro CS4 – resizing rendered video without compression?
Hi and thanks in advance for any help on this subject:
Is it possible to resize video when rendering using CS4 without losing quality (eg: without compressing the video)? I’m using 1080i avchd source video and final resolution needs to be 720-405 (still 16:9). I’ve included a description of my situation below but if you don’t have time to read it any general tips would be great thanks. I basically need to render video in 2 stages – 1st stage to resize without losing quality, 2nd to compress with reduced bitrate for web streaming. I’m fine with settings for web streaming inc. bitrates (I’m using flash flv for streaming), but my question is: what is the best format / settings for resizing video with minimum compression / picture degredation?
I’m bascially having a problem with some psd files which are integrated into the video sequence. The videos are for music tuition and the psd files are the music score (lots of thin horizontal / vertical lines). When I include the psd scores with the original video (1080i) it displays fine in premiere but due to resizing by less than half, the score lines effectively disappear (reduced to about 1 pixel width!)
Previously I’ve had to redraw the score lines in photoshop which is too time consuming. So I’m looking at the possibility of editing the video together and exporting to the correct webpage resolution (720-405) without losing quality (if this is possible), and then integrate with the psd score files in another sequence. So when I export the final flv video for web streaming the psd score hasn’t been resized and should be still legible.
Phew! Hope that makes sense and thanks for any export format / settings recommendations.

Hi Sion
I think your idea if resizing the video first and then integrating the PSDs sounds a sensible approach.
What you could try is creating a sequence that is 720-405 and dropping the full sized video into that and simply use the motion controls to scale it to the right size rather than exporting it. When scaling down you won’t lose any quality so it shouldn’t cause you any problems. Then, once you have rescaled the video you can add the photoshop documents and export that sequence. Thus only actually exporting once!
The issue is always going to be the FLV export which could well cause you some problems with the narrow lines! It may make some sense to add an effect to the PSD to make the lines stand out more. And, you could try one more trick.
On a new sequence, add two copies of the psd one on top of the other. On the top PSD add something like find edges or some other stylise effect to make the lines stand out and then try a blending mode on the two PSDs to get a really stand out effect (blending modes are under the opacity tab). If the effect is rather too much, use the opticity controls to ‘dial back’ the effect on the top layer until you have something that looks strong enough.
Then, instead of adding the PSDs, add the new sequence with the blended PSDs and then try exporting a short version to see if it works.
Also, you could try exporting to F4V instead of FLV as this is a flash version based on H.264 which may do a better job for you.
Anyway, have a play – sorry if none of this works, but it’s worth a try.
All the best
Andrew… because it’s all about stories …

Hi
Thanks a lot – some great advice. Thanks for taking the time to read the post details as well since your overlay idea for the psd files could definitely work. At the least the resizing of the source video to be able to export at the same resolution as the sequence should make life a lot easier.
My website database is set up to accept flv files (not f4v unfortunately) so I’ll try and find a solution for these initially. My working knowledge of Premiere is pretty ‘specialised’ so it’s great to hear of some new approaches!

By the way the videos in question are for guitar tuition – let me know if you fancy a few freebies 🙂
