1.5 vs 2.0 Export Performance
Hello,
I just came back from my editor’s place where we tried to export and old project again (we had to make a tiny edit). This normally takes a few minutes…today it took almost 3-4 times that. He upgraded to PP2.0 and reckoned ever since everything had gone down hill. We spent two hours and got to the bottom of why my project exported slow.
It’s basically 20min of DV footage with NO effects, just dragged straight on the timeline. Then there are several still image photos that are superimposed at different stages. Only fadein/outs where used. That’s it!!!
We opened this original project in 1.5 and said EXPORT – MS AVI – Uncompressed – 48khz Full Audio. It zoomed through the export. On the same machine, we opened the SAME project in 2.0. We changed nothing and said EXPORT – MS AVI etc all again…it took ages to export. I thought he may have screwed a preference setting. Nope, all set nicely…basically the same where applicable as in 1.5.
We ripped out the underlying DV incase we thought it suddenly developed issues with video exporting, and yeah, it exported full speed. Then we replaced the DV again and ripped out the whole track with the photos. Hmmm…also same speed as 1.5 (give or take a couple of seconds). Put them both together again and you have the ice age knocking on your door before the export finishes.
Here are some tests cases we have gone through:
1. It’s not due to opening old 1.5 projects in 2.0. Re-creating a basic project with one dv-clip and a still image on top does the same.
2. It’s not hardware, we tried it on two machines, both times we did exports from 1.5 AND 2.0 on the same machine back-to-back with massive differences in export time.
3. It’s not any codecs – we’re exporting plain simple uncompressed AVI, lower field first…this should technically be one of the faster export methods as no compression needs to be done.
4. It’s not the photos. We have imported plain TIFFs, PSDs, jpegs, BMPs…it’s apparent to some extend on all formats.Could someone please, PLEASE try this and tell me that what I have seen has a simple solution? Like I said…new DV project (we used PAL DV, 48khz), put DV clip on VideoTrack02, import a PSD, put PSD still above the whole video track. Now save and export as avi in 1.5. Open same project in 2.0 and do the same export again and check the export time.
The biggest delays appear to come from using PSDs. We discovered this right at the end and that was enough for my editor friend to snap and me to realise upgrading could be very foolish. To think adobe’s own PSD format cannot be placed over DV footage without massive hits to export times is quite disturbing…hence this post to see if someone can either replicate this or provide a solution as I’m looking at buying the new production suite and definately can’t have this happen.
Many thanks.
Lev.

Hi Lev,
I also have problems to export from ppro 2.0 and I’ve now read many posts here and on Adobe’s forum about that question. There is no doubt ppro 2.0 has a bug with it.
On my side, I made a test with only one high resolution still (4000 x 4000 pix), for a duration of five seconds, on wich I applied some scaling effects (different values between in and out point). I noticed that if the values were under 50 (in “49”, out “30”, for example), the rendering time was a few minutes, if the values were over 50 (in “60”, out “100”), the rendering time was a few seconds (see my post below).
We all know ppro 1.5 had a problem with high res stills (green screen when calculating), we are now all discovering they have solved the green screen by amazingly slow rendering.
The question is 1/ how is it possible that beta testers of a company like Adobe didn’t notice this problem (if you add they already had a still problem with ppro 1.5)? 2/ how to persuade Adobe to solve quickly this problem, considering they usually don’t like to admit their own mistakes ? We will first be told : “are you sure you have the problem”, then “It must be your computer or XP”, then “you should reinstall every thing”, etc. Many will loose hours and days for nothing. And the reply “this very long calculating process is the price for a (so called) better quality” is not acceptable for a software called “pro”.
Adobe, could you please hear your customers ?

billyj:
Do you get the same slow rendering/exporting, if you use a 1000×1000 PSD (or jpg, etc.) still, in your 5 second test, when you scale below 50%?
Keep Smiling
