premiere CS5 vs CS3 – why adobe did that to us ?

[Vince Becquiot]

Hi Piotr,

[Piotr Niewinski] “1. Try to work with sequence of files, f.e. with TGA sequence. When you put it on timeline you should render preview – especially in HD, and in CS3 it goes (on my system) about 10-15 frames per second – it is fast. In CS5 it goes about 1 frame per second – it is horrible slow. I tried different formats, different sequence and preview settings – everything – always slow in CS3 always fast. Why? CS5 is horrible fast with stream video like AVI or MOV, but what about sequences?”

You haven’t mentioned your system specs, I do have to render as well for a completely smooth playback (I get about 20 fps on our i7 machine,no CUDA card), but my guess is the Mercury engine would solve that. TGA sequences are quite a bit different from AVIs.

[Piotr Niewinski] “2. Where adobe took from such strange pixel aspect of PAL – 1.094 ???
What a shit! I’ve never seen such thing, PAL aspect is 1.066 or 1/1.066 as you wish. It is not possible to correctly work with PAL in CS5. You cannot change/set pixel aspect to be proper. Hopefully most of projects are HD nowadays. But when you try to downscale HD to PAL in CS5 you take a shit!”

It is not incorrect. I believe up to CS3, they used to use NLE PAR, it now uses ITU.

You don’t have any third party plugins in CS3 that you don’t have in CS5 do you? I know Pinnacle’s bigger system was sureally fast with Premiere and TGAs once upon a time…

For the most part, if the system you are running on is spec’d to run CS5 (which means it would be a monster for CS3), I don’t know why you’d experience this…

I know that the use of TGS frame sequences has dropped of significantly over the last ten years, but I have no knowledge of PPro somehow dropping (or altering) support for them.

I know that TGAs are not so popular nowadays, but it happens to any sequence format (TIFF, JPG, BMP etc.) Premiere is going to support sequence files for sure – they added f.e DPX support in CS5.

I do not have any plugins etc. I talk about very simple usage: open new project, create a sequence, import a sequence of files and try to render preview or export them as any other format from timeline.

[Piotr Niewinski]

I have some systems and tested on any – from dual Quad HPXW8400 to i7 980x with 6 cores and Win7 on MAC PRO dual Nahelem – all with Quadro, FC SAN and lots of RAM, all Win7 x64.

Thanks for link with pixel aspects – i’ll study it later, but consider:
I had 4:3 with 1.0666, now I have not 4:3 with 1.094. Do I have to change my televisor now cause it is 4:3 as I guess?

[Shawn Miller]

Odd, I get full framerate playback using .tif sequences in PP CS4 and CS5… but these are 8 bit images with no transparency. Do your .tga sequences have an alpha channel by any chance… also, are they 16, 24 or 32 bit?

Thanks,

Shawn

Regarding the change in pixel aspect ratios (PARs):

They were wrong for many years. In fact, they were wrong for so long that many people came to think of them as “right”. But many broadcasters and software and hardware companies surely didn’t. Many of our customers and partner companies urged us to correct this longstanding mistake. So we did.

Note that Apple and the Foundry followed suit soon after, with Final Cut Studio 7 and Nuke both switching to the corrected numbers in bug fixes soon after we made the change.

I give links to lots more detail here, in a post that I wrote for CS4.

Ok, I understand the pixel aspect – I’m one of the “right-thinking” ;).

But what about support of sequences. CS5 is really slow with sequences.
It looks that trying to speed up whole Premiere somebody made a bug with reading sequences. Can anybody chceck it at Adobe?

If you still have a problem after installing the Premiere Pro CS5 (5.0.3) update, then please submit a detailed bug report so that someone can look into it.

Thanks Todd for quick reply.

I’ve updated to 5.0.3 every system few days ago and problem still exists.

Many days ago I send “detailed bug report” to Adobe about that, but there is no answer and I do not even wonder there will be… ;(

I wolud be very gratefull if you or anybody colud help me “directly”.
Please chceck this issue on your own and tell me that I’m wrong.

To be clear I’ll summarize:
I’m talking about such scenario: put sequence of files on timeline and try to render preview (to AVI f.e.) or try to export media from that to AVI or QT f.e.
Both will do very fast with CS3 (and as I remember CS4)(in HD about 20fps on average system) but in CS5 it goes 5-10x slower.
I test it every update and with different settings like HD720, PAL, other sequence formats etc. and spend a lot of time with it.

Every time I’ve project with sequences I use CS3, when working with stream (AVI QT or R3D…) i succesfully use CS5.

Bug reports don’t always get answers, but they do help us to find problems and fix them.

In case your response was meant to imply that you didn’t believe that the bug reports are even read, I will reassure you that they are. I work closely with the person who does the first pass on reading them and assigning them. (I’m the person who reads all of the After Effects bug reports, by the way.)
