Choppy playback in preview window

I've seen many threads about choppy playback in CS3 and CS4, but no answers -- just people saying "I have choppy playback, help!" and others answering "I don't have choppy playback, you're nuts."

Well, I'm nuts then.

I just built a new PC to upgrade to CS4. It's a dedicated shrine to Adobe -- nothing else on this machine except CS4 and windows XP SP3.

Memory: 4GB of DDR2 memory.

HD: four SATA hard drives.

Video card is ATI Radeon HD 4800 series. Nothing fancy.

I optimized my machine specifically according to the Adobe recommendations. New fresh WinXP install on new clean HD.

The same clips that looked and played back fine in CS2 on my slower WinXP SP2 machine are now stuttering and stammering in the preview window.

I'm voicing the same frustrated cry as many before me. "Don't tell me I have to revert back to CS2!"

There doesn't seem to be any point in going to CS3 since many have complained that projects that looked fine in CS2 were choppy in CS3.

I'm going to try settings on the video card. But seriously, there are too many people having this problem for it to not be solvable or at least identifiable.

I'm exporting my first video file and I am holding my breath. If it exports as choppy video then I may throw my hands in the air, revert to CS2, and curse the name of Adobe.

I had the same problem and no one had a good answer. I figured it out. I am using Windows 10 that had directx 12 installed and I downloaded directx 9C and it solved the problem for me.

Yeah I had the same issue. I was finagling with the audio and found out that that if I set it to Mono on the clip it would fix the playback issue. To do this you would right click on the clip, go to modify, hit audio channels and then you will see the option to change it. Hope this works

Here is what to do, well at least what i do. When you have all the selected footage in the time line , there will be an opt under Sequence "Render Entire Work Area" , Once you do that your footage will have smooth playback. Let me know if that helps.

I used to get stuck with this problem. I finally solved it by changing the "video playback settings" from "the sequence settings" in the "sequence" menu. The default resolution is 1920 x 1080. I changed it to 640 x 360, and after that playback was always 100% smooth, even while using a mixture of .mts and .mvi full HD files, with contrast and brightness effects on them, without even having to render at all, even while the bar is red.

I have run into choppy/stuttering video in the preview pane of and on with various causes. Here's something to take a look at: your "flavor" of video files. I have no problem with video from my latest dv camera....BUT when I do a screen recording with Camtasia (running Studio 6 now...) and use that app's .AVI format, i have choppy problems.

Solution: reconvert Camtasia's .avi videos. I use (AVS4You) AVS Video Converter 6.

I have not looked closely (or can't tell/care) if quality is lost in the re-conversion, but once I reconvert and reimport, render, the video looks fine.

I was having the same problem with a radeon 4800 card, fixed it by rolling back to older v8 drivers. But was having other issues with those. After mucking around I figured out what was causing the problem.

The ATI help file says this

"

Enabling Smooth Video Playback

Under certain conditions, video playback may appear disjointed due to dropped frames. To ensure smooth video playback with no frame drops, enable Enforce Smooth Video Playback.

Based on the navigation system contained in the ATI Catalyst™ Control Center window, do one of the following:
- Navigation menu—On the Graphics menu, click Video.
- Navigation tree—From the tree in the Graphics Settings tab, click Video.
Click All Settings.
Scroll to Video Playback.
Select Enforce Smooth Video Playback.

Which is checked by default but once I unchecked it my playback went to normal.

Somehow I doubt it is a hardware issue, I'm starting to believe it's premier itself.

I am running 12 GB of RAM, quadcore, 4TB hard drive space with 2 x 512 DDR 3 graphics cards. It's a mac specifically built for editing, and yet, premier still lags terribly when previewing.

I am using 30 FPS footage interpreted to 25, then sped up to 120% to be syncronised with the audio recorded on a diffferent cam (dont ask why it is sped up to 120%, it's the only way I can get the footage to be consistant regarding speed. Yet, when I put the finished file eventually in media encoder, it renders out and the audio and video are unsyncronised.

Premier is starting to look like a waste of time for me.

i'm having the same problem :S

it's absolutely impossible to edit something like this!!!!! it's like running at 2 fps and randomly freezing...

did anyone fix it?

i've got an i7 920 processor and 3gigs of ram. running default with all the latest drivers.

i tried re-installing all the codecs and even defragmented the hdd.

it actually kind of freezes the whole program too... like the space bar is slow in responce and the whole interface looks funny slow....

i've got a dvi cable if that matters...

If it aint broken, don't fix it. The fact that yours is broken means one of three things, either your setup is wrong, your material is unsuited or it is OE. The alternative is that a combination of these factors apply. Hard to tell without relevant details.
