Am I doing it right ? Route 66 video ?

Ron, let me jump in here for just a second. I am thinking that I have this rendering where I understand it with all the help that I received from you people a few days ago. But here I have to ask one more question. If you are in the edit mode and say that you add a transition. Now you go and play the project and now you wait until it smartrenders. Now you have thought that you want to add another transition. You add that transition and now you go and play the project again to see if you have the right effect that you maybe want. OK, now it smartrenders again. Is this normal or am I maybe doing it different from what you guys do? I hope that I have explained myself to where you can understand what I am asking.

Thank you.

Nice and clear, and I do it all the time, playing around. Most of the time for the videos I will use for my final product (DVDs) I mainly use the cross-fade, and Fade-to-black. However for viewing how my PIPs, texts, etc., are going to look, and I'm using the High-Quality Playback, it smartrenders the project or preview range that I have selected.

Now keep in mind I work only with DV. I do have several MPEGs that I toy with, and really haven't noticed any degradation, and they have been through the SmartRender mill...

Thank you Ron. You have been a great help to me and to everyone else. I really appreciate it.

Just to clear up the bit about smart rendering.

If a piece of video is completely untouched - no cuts, no transitions, no filters, no titles, no new sound and so on, then it can be smart rendered.
This means that the program simply copies what is already there from the old file to the new. Obviously because there is no work involved it is very quick.

If you alter the video in any way - that's all the things I mentioned above plus any other form of change, frame rate, dimensions, bit rate - anything at all, doesn't matter what. Then that part of the video has to be rendered - or if you wish created. It can no longer be 'Smart Rendered'.

Only the changed bits are affected not the whole video.

Lets say we have 2 clips both are 3 minutes long and we join them together using a 1 second transition. This is the only change made, we haven't altered anything else. The two clips will smart render with the exception of the bit where the transition has been inserted.

Hope this clarifies things.

Steve, thanks to you also. You and Ron have really made this clear to me. I appreciate all of the help that I have received on this subject.

Thanks again.

Hi John / Ron / Steve

I have read these posts and think there may be some confusion as to rendering.

John

Please go File-Preferences-Playback Method

This option changes the way the project plays in the preview screen.
If you are having trouble with playback then choose High Quality Playback
This creates temporary files in the Preview Folder then plays the project from these files. See the location of this folder from File ¡V Preferences- Preview tab.

From File-Preferences-Playback Method you have two choices--- what have you selected

If you haven¡¦t already please select Instant Playback

Now try your editing.

Trevor

Hi yes thanks, so the main video file that i captured stays as it started, all the other files are not edited versions of the original files but files telling Ulead where the cuts/transisions /titles are thats why they are small files and when it finally renders you get the video and all the cuts etc, but the original capture file is still as it was ?
When does your p.c work the hardest, capture/ editing/rendering etc

Hi Trevor, yes in the past I have had the playback method set for high quality playback. Everyone has told me to set it for "Instant Playback". That is what I am setting it for. I am anxious to see the difference that it makes. I do believe that I have a better understanding of all this now. I thank you very much for your help on this.

Are you sure about this one Steve? I regularly replace my entire original audio, and it seems like it is still being smart rendered. The first 10% or so of the 'create video file' phase takes longer than normal, but the remaining 90% flies through at the same rate as if I hadn't changed anything. Also, the preview screen remains black rather than showing the video being rendered.

I get the same sort of effect if I simply change the audio settings only (to convert mp2 to ac3 for example). I'd always put this down to the first 10% being taken up by the new audio while the rest was indeed being smart rendered.

peace.

Some things render quicker than others. audio is quick, video is slow.
To demonstrate that take a piece of video and now create two files
(Via the share tab)

Create video will take significantly longer than Create Audio.
The preview screen only appears to display when the video is being rendered, not the audio.

You can also test this for yourself by taking a few clips all with the same properties and simply join them with. Now render it and you will see the start/stop/start/stop effect of the video preview screen as it reaches each of the parts that have to be rendered. You will also see the progress meter slow down and speed up at these points.

O.K, yes, I realize audio takes a fraction of the time video does. I had read your comments as saying that if extra audio was added to a project then the video couldn't be smart rendered, which didn't gel with what I was seeing. Apologies for any confusion.

peace.
