Short clips Ok, Long clips choppy.

[wallygoots]

Greetings,

I have a series of clips put together totaling about 20min. of video that I want to render. If I highlight the individual clips in the timeline and play them in preview all is well. (Rendering of specific clips also seems fine). If I try and play the whole video, it's choppy. It's not just lagging, it seem like it's stuck in a loop for a fraction of a second before progressing. Audio is fine though. I've tried rendering in a number of different formats, but it's all the same chop after output. Single clips are fine but multiple clips look like poorly done stop motion.

I'm using Windows 7 Ultimate 64bit, 6-Core processor, 16GB of RAM. The weak link is integrated graphics. Would that be enough to mess up a full render? The video footage is coming from a hacked GH1. AVCHD I think. I've heard that this is hard on a machine. I can't figure out how to convert to a different footage without redoing the whole project.

Thanks for the help.

Interestingly, I can play a really long single clip (of say 24min) and render it successfully. But two clips in the time line even if only a couple min. each is a no go. I can't figure out how to merge the clips in the time line together to give that a go. Very annoying.

Thanks for the help.

Hi wallygoots

Welcome to the forum

First, Avchd can be very demanding on the pc, Video Studio uses a process called Smart Proxy.
The process creates additional files used to smooth playback and therefore improve editing, maybe using Smart Proxy will help.

There are two types of playback, Clip Mode and Project Mode, note the word adjacent to the play button being highlighted. Clip plays individual clips whereas Project plays all timelines..

Can you give us some more information……………
1 / What version of Video Studio are you using?
2 / Right click one of your clips in the timeline and select properties, what are they?
You can create an image of that window and attach to your post, attachment options at bottom of your post.

3 / what are you intending to make? Burn a Disc, video for the internet, if a disc would that be standard definition or High Definition?

Greetings Trevor,
Thanks for responding. Smart proxy is enabled. I see the clip mode and project mode buttons. I'm intending to make a file and eventually a disc. This is the first act of a play. I was going to do the other acts separately. I'm using VSP X6 and when I right click on the file I get this info:

MPEG-2 (Transport Stream)
H.264
30666 frames (this is one of the longest clips)
24bits
47.9fps
Variable bit rate
192 bit rate (audio)

Best,
Seth

Hi Seth

Can you create an image of the properties window and attach to your post.
Using keyboard Alt + PrtSc will copy the window details to the clipboard, paste this to an image editor to create the image.

I ask as 47.9fps is very unusual, or is that a typo.
Generally there are two options:-
50/60P and 25/29.97 fps (Pal / Ntsc)

If you are using 50/60 then you can activate that option from the Settings menu.

If you create a video using 25/29fps you are stripping a lot of frames from the 47.9 resulting in poor quality.
But as I say 47.9 is not standard and very strange.

If it is indeed 47.9 where did you get the video from?

And just to confirm when you say you intend to make a disc, are you referring to a Standard DVD or Bluray HD disc?

Finally, where do you live, are you using Pal or NTSC?

Here is the properties box. I'm in the US, using a hacked GH1 micro 4/3rds camera. I was planning to make a standard DVD disc from the file if I can get it to work. Uploading to Youtube is also an option or I could just distribute a digital file. It's a class play.

Hi

As far as I can tell by googling the camera it will record to Motion Jpeg or Avchd
Both would use 29.97 or 30 frames per second.
As your frame size is showing as 1920 x 1080 I assume the recording used AVCHD

I don’t understand how you are showing a 47.92 frame rate. That frame rate is completely wrong.

Have the original video files been converted in any way.?

Do a short test recording in AVCHD mode, insert to Video Studio to view the properties, are they the same?
