Premiere CS5 Choppy/Skippy Render Issue
Hi, I am hopping that someone can help me with the issue I am having rendering a music video in Premiere CS5.
I shot the original footage with a Sony Ex1 camare 1080, 60i 29.97 fps, and I am rendering to the same format.
The project plays smooth in Premiere. However when I export the video skips in two or three spots. It usually happens when there is motion on the video (Someone walking etc..) NOt sure why. I have been rendering for a week now and I feel that if I continue, I can declare myself insane. This is why I need someone’s help please.
Now once I import the rendered footage back into premiere it does not skip. It plays back perfectly.
I am exporting to MPEG2 and I tried various bit rates, and same issue happens. It is important to note that it never skips in the sma place when you render on a different time.
The skipping happens when I view it on Windows Media Player.
Can anyone please help.THanks,

Are you exporting to a DVD or BluRay appropriate MPEG2 profile?
It may just be that the data rates are too high. What happens if you export to WMV?

HI thanks for the quick response. I tried exporting to MPEG2 with settings for blue ray 30mbps, then 18mbps target rate, all the way down to standard definition and the skipping/jumping does not go away. Tt just happens in different places. I just rendered one more time and applied frame blending this time, and the video was smother, however there was still three places where it stalled and skipped.
I will try rendering as wmv, I have not tried that… I will get back to you with the results. Thanks.

Windows media player will choke on data rates that high. If it it ok imported back into premiere then it is not really a problem.

Thanks for your quick reply. I tried under exporting to WMA at 8mpbs. You are right, it totally choked. Ohh my god. The picture was frozen on some frames and the sync completely colapsed.
Ok now the issue I am having with the MPEG2 to is that it is skippy on those two scenes. This video is to be broadcasted on a pretty large TV station out of europe and they require MPEG2. They play it off of Windows Media Player and then transfer the video I believe on Beta tapes to put it on the air. Don’t ask me why but they do. I just sent them the MPEG2 that I render that has those two flaws in it and right away they noticed. They stated that they will put it on the air this weekend but that I have to fix it. Please help me with this. I know it is fine in premiere but they don’t play out of premiere and it is a problem for them.
Thanks,

Ok folks I just rendered to PAL NTSC MPEG2 with lower field first, target bitrate 7mbps and high bitrate 8mpbs, and the result is that is skips in three other places.
OK so I took the file which was HD NTSC which skipped in a couple of places, then imported into premiere, it played perfect, exported to PAL (above) and the video is jerky, stalls a bit in three completely diferrent places.
Original footage was shot with Sony EX1 in mp4 format.
Yes and I did try to export in mp4 format before and it does the same thing. I have been rendreding for more then a week now:-))
Please help.

FYI, when I uploaded the file to youtube. Youtube seem to correct the problem. However, I really need the mpeg2 to work well for the broadcasting on the TV station.
Thanks so much for your help with this.

I’m not sure it’s very easy to give you much insight without some more information…
You shot on an EX1 so you shot XDcamHDEX, either at 25 Mbits/s or 35 Mbits/s…it’s MPEG2 in an MP4 wrapper.
What is happening at the two points where you had the problems with the MPEG2 HD export? Is there an effect on the footage that may not be rendering properly?
Have you tried to render the entire sequence (in the sequence pulldown) so the timeline shows green and THEN try to export? I’ve noticed there are certain effects that do not function properly in Media Encoder when using PPro headless to re-execute the file (any Magic Bullet Looks stuff for instance). So rendering the entire timeline in preview, then checking “use preview files” in Media Encoder can trade a little quality loss for some malfunctioning effects…
…but I’m guessing as there isn’t much to go on.

Tim, thanks for your reply neighbor. I am in Chicago, Illinois by the way. Anyhow, I am using Looks Builder and Neat Video plugins. I shot the footage in NTSC 1080/60i, and yes you are correct mp4 is the wrapper. You know your stuff:-))) At this point I will try rendering with preview files because i have not tried that.
The other thing that is odd is that once I import the rendered video that gets stuck on two scenes into premiere, it plays fine. When I render the rendered video(and this version does not have looksbuiler and Neat video, becuase it was the rendered version) it plays fine in premiere, but renders and gets jammed in two different spots:-(((
I also imported the footage to youtube and it is smooth there. So apparantly youtube fixes it.
I am new to video and don’t have a lot of experience with this but, I am beginning to think it is my machine.
What are your thoughts. I have a Dual Core, 2.53ghz per core, 4gb of ram, 256 mg nvidia video card laptop. I know this is not impressive to that fanciest i7’s out there. I will go and buy one if you think that this will fix it.
What are your thoughts? Thanks again for your patience and help.

Tim, FYI. I just rendered and selected export with preview file. The video stalled in two spots. Unbelievable.
Any thoughts?

Are the “spots” it stalls consistent?
There is something wrong with some media or something inside the project…
Have you attempted to import the project into a fresh project? That’s the typical first troubleshooting step…
