Womble editing - puzzling extra frame

[terrypin]

This is really bugging me, so I hope there is a Womble Wizard user around who can help please.

1. I drag a clip into the input window

2. Navigate through it with the slider and the arrow keys until the scene changes from A to B

3. Go back one frame with the left arrow key, i.e. to the very last frame of scene A.

4. Click the Mark Out button. The green bar appears, which should now exactly represent scene A.

5. Click Ctrl+e, Add to Clips

6. This new clip, scene A, appears in the project pane.

7. BUT - if I now drag this back to the input window to check, when I play it or drag the slider to the right, the fisrt frame of B is somehow still present!

This may be because of an open GOP. The last frame of the previous GOP may need the first frame of the next GOP for decoding.

Thanks, appreciate the fast reply. Can't say I'm savvy about GOPs etc, but it's reassuring if it's not a Womble bug.

This is default behavior of Womble, which is more accurately known as MPEGVCR as Womble is the name of the company, not the product itself. It has ALWAYS done this, but I don't know why.

By the way, your edit method is not ideal. To be fair, it is counterintuitive, but your method of removing video from a clip is causing MPEGVCR to do major re-encoding, which is NOT at all what you want. The only way to edit with this product is to mark the beginning and end point of what you want to keep and save it to a clipboard. Repeat if you have other segments. Then join the clipboard segments together into a single file. This results in less encoding by MPEGVCR, which will now re-encode the absolute minimum possible to render your edited clip. It's not your fault as like I said this is counterintuitive, but a guy I know several years ago did a test and figured out that this was the best way to use MPEGVCR to edit. It's not that tough to get used to. You can sometimes have audio sync weirdness if you use your method of removing clips from a video file, which is how the guy I know figured out that removing video was bad, but joining video was good in MPEGVCR.

Thanks, but by 'Womble Wizard' I don't mean MPEGVCR. (I have that too.) I mean Womble MPEG Editing Wizard (DVD version).
