Some videos clips stuttering in preview

iamgregor Sep 28, 2013 10:25 PM

I tried reimporting the video and translating it to another format, I've rendered it fully, and deleted temp files and re-rendered it. I rebuilt the video from scratch in a new sequence created from the clip (all clips were screencaptured using Camstudio so they're the same exact format as each other.

But I still have constant problems with videos not playing properly in preview. The last time I had this problem, they rendered that way too. When I hit the spacebar to view the video, it shows a bit of the video, then rewinds and plays the same section over and over, moving a little further forward each time. Basically "rubberbanding".

It's Premiere Pro CS 5.5.2

Win 7 64

No third party codecs.

I have plenty of hard drive space and 8 gb of ram. I do have browsers open which use a lot of memory, but all the other clips are working so that doesn't seem like it should be an issue.

I'm not using any kinds of plugins or third-party things.

Some things that help: Shutting other memory hogging programs and restarting Premiere.

Things that seem to hurt: using the time slider to increase or decrease speed of the video.

Please open task manager & switch to resource monitor while playing the clips in Premiere Pro, if its a memory related issue then you will be able to view the details there.

Sadly that doesn't seem to help. I have at least 3 gb available and there's no strange activity. Even if I step through the clip one frame at a time, the video jumps from place to place. I can see it progress forward, then it jumps back a few frames, then forward again each step. It's maddening.

I've tried making a new sequence and editing the video there to see if I could insert the sequence instead.Still no good.

Hi Greg,
Please let us know the source of the footages that you have used in the project. Are you working in GPU acceleration or software only mode in Premiere Pro? Please check the performance of the program in safe mode.

Greetings. When it comes to screen-capture, the clips are usually really complicated for programs to playback since they are of an extremely high bitrate most of the time. If they are in .AVI format, it's even more complicated for the software. I recommend converting the footage to a more palatable codec like H264/MP4. There's an open source program called Virtual Dub that can help do that for you.

I tried a variety of formats without much luck, but it seems that standard WMV (windows media) seems to work without stutter so I'll stick with that for now.

By the way, Any Video Converter and Handbrake are both much better for re-encoding video in my opinion compared to Virtualdub.

Interesting to have stumbled on this thread. I'm only a recent user of Premiere Pro and have been assembling some software training videos. Using CamStudio, current version - and, yes, I know it's free and you get what you pay for - but I'm stymied as to why this stuttering problem seems to have spontaneously started. I had recorded several segments using the same recording settings and codec that played back fine on PP. Now it stutters and jumps video frames like crazy. Static screen, no problem, but moving the mouse or dropping menus as there are gaps between the frames as things jump back and forth. The audio is unaffected.

I am using the Microsoft Video 1 codec, tried DivX with same result. CamStudio's Lossless Codec wouldn't be read by PP. I have the compressor quality set to 100 in the CamStudio config, with keys every 30 frames, and framerate capture and playback at 50ms and 20fps respectively. Don't know if this is standard but CS demands that the multiple of those framerates equal 1000. I also tried combinations of framerates.

Is there a magic combo of key/capture/playback that I'm missing? I'm just at a loss as to why things all of a sudden stopped working.

Install Lagarith and use that for recording.

Jim, thanks so much for your input. Works like a charm. Still clueless as to why all of a sudden things crapped out. But this is great. Can you offer any input on preferred settings for software screen capture, relatively little movement (menus and mouse primarily)...

Default is probably best.
