Adobe Premiere previews lag when previewing on my laptop?

Postby AnimeSpiritZ » Tue Jul 21, 2009 7:05 pm

When I preview my amv project on my laptop, it seems to lag very badly. But when I preview it on my desktop, it barely lags. I am currently using the v210 codec to preview my project, since I am unable to find a way to enable ffdshow to preview my project on adobe premiere. My laptop has 4gb of ram, while my desktop only has 2gb, so i'm a bit confused at the moment. Are there any suggestions? Previewing with the other codecs arent helping either, unless there's a way to enable ffdshow for premiere pro cs4.

If you have a 64bit OS, then you're limited in your codec choices for preview. You should just try switching preview codec until you find one that's fast enough. I use ffdshow myself since its mjpeg preview is really fast, but with 64bit OS that's no choice unfortunately...

Then it's really weird. Is it also not available between the codecs for the export? Or is it only missing in the preview list?

yeah, it's only under Video Previews that the codecs arent there. For Exports, under Microsoft AVI, I have the following codecs available:

Cinepak Codec by Radius
DivX 6.8.5 Codec (2 Logical CPUs)
DV (24p Advanced)
DV NTSC
DV PAL
ffdshow Video Codec
Huffyuv v3.1.1 - CCESP Patch v0.2.5
Indeo(r) video 5.10
Intel Indeo(r) Video R3.2
Intel Indeo(r) Video 4.5
Intel IYUV codec
Lagarith lossless codec
Microsoft RLE
Microsoft Video 1
Uncompressed UYVY 422 8bit
V210 10-bit YUV
Xvid MPEG-4 Codec
None

And under Video Preview's Desktop > Microsoft AVI codecs, I only have:

DV (24p Advanced)
DV NTSC
DV PAL
Intel IYUC codec
Microsoft RLE
Microsoft Video 1
Uncompressed UYVY 422 8bit
V210 10-bit YUV

The codec packs i've installed before are Combined Community Codec Pack and AMVapp. The other codecs were installed individually.

That is indeed weird. As far as I knew, this issue was only on Vista 64bit... I suppose that you could try checking how the other codecs available work. The DV codecs might do well for preview purposes, just be sure to pick the right one depending on what your project settings are. If this ain't be enough, then I suppose you're better off exporting the timeline every time you need to preview...

the other codecs dont work well either. and what's weird is, when i try to preview with DV, the video gets all sliced up. like, the entire video is moved downwards and i cant view the bottom half of the video, as if it just gets cut off or something. Microsoft RLE is the least laggy, but the video output is very bad too. Not foggy bad, but more like i can see "moving blocks" of bad video conversion throughout the video.

Actually, I just downloaded the update for Adobe Premiere CS4, it seems to enable "I-Frame Only MPEG" under Preview File Format. This allows you to preview your project with MPEG files instead of avi. It previews quite smoothly for me than any of their Microsoft Avi codecs. If only I could get ffdshow to work in previews though. There's also a "Maximum Render Quality" check box under the same windows. Just saying this to let people know in case anyone is having preview issues like I did, and hope that it helps.

How is ffdshow set up? You might need to make sure that the formats are set to decode on both the DirectShow and VFW interfaces. By default, the VFW interface is mostly disabled.

Also, make sure you're using a recent build of ffdshow (I go with the most recent generic SVN builds by clsid):
http://sourceforge.net/projects/ffdshow-tryout/files/

Can't be sure but apparently yes. At least in this thread, it seems as if on 64bit OS both 32bit and 64bit codecs won't work for preview.

I just downloaded the newest ffdshow build (generic SVN build by clsid).
In the ffdshow video decoder configuration, I unchecked "Don't use ffdshow in" under DirectShow control. I also enabled every codec to decode with libavcodec under Codecs.
In the VFW interface, I also enabled every codec to work with libavcodec. I'm not sure what "Raw Video" is, but I turned on "all upported" for it.

I'm not sure if this is all I had to do, but the codecs are till not available to encode preview files for Premiere Pro CS4.

On the DirectShow control page, when you unchecked 'Don't use ffdshow in', was Premiere in the list next to that checkbox?

Likewise, are 'Use ffdshow only in' and 'Show dialog when unknown application tries to load ffdshow' checked or unchecked? Is Premiere in the list next to 'Use ffdshow only in'?

I'm not sure what "Raw Video" is, but I turned on "all upported" for it.

Raw Video is simply Uncompressed video, the different options under it refer to which specific colorspaces it should handle. For instance, if you told it 'All YUV', it would handle just Uncompressed YUV, and you wouldn't need the Helix YUV codecs to make AviSynth work right.

Yeah, premiere.exe was in the list next to "Don't use ffdshow in." But I practically erased everything on the list and unchecked it.

Likewise, are 'Use ffdshow only in' and 'Show dialog when unknown application tries to load ffdshow' checked or unchecked? Is Premiere in the list next to 'Use ffdshow only in'?



After reading this, I just followed these instructions. But I still dont see the codecs after re-opening premiere.
