cut content in output file

[Anonymous]

I have been cutting commercials out of several tv programs that I have captured from Dish Network using PVR-250 capture card. I have noticed that after I remove all the commercials and check the output file that I have several seconds of a commercial left in at the end of the file. I also noticed that when I recorded two shows and I cut the first one completely out and the commercials in the second, there were left over commercials at the beginning of the output file. I do have frame accurate cutting enabled. I am worried since I have not previewed the whole output file where all the cuts were done, that other cuts later in the clip may be affected as well. It appears that about the hour point in a file, the accuracy of the frame cut is off. I am capturing and editing in CVD vbr format if that makes any difference.

Do me a favor, please. Run Tools>QuickStream fix on the file first and then do the cuts. See if that fixes the situation.

This isn't a known issue, so I don't have a fix until we can determine the cause of the problem.

Yes, that did fix the problem. I looked at the cuts and it appears that only the last cut was not accurate without the quickstream fix. I understand a little what the quickstream fix does, but why does it shorten the mpg file so much? It took about 100mb off an hour show that was about 900mb to start with.

Yes, that did fix the problem. :) :)

What going on is that the time codes in the file are not necessarily sequential. VideoReDo attempts to recognize this when the file is loaded by sampling at various places in the file, and can compensate automatically. However, there are situations were the sampling just doesn't work because the break in the timecodes occurs at the wrong place with a sample. By nature, sampling isn't exact. QuickStream fix realigns all the timestamps which why the final edits worked.

Did I miss something, or is there a way to view frame numbers on the screen?

Thanks

In our latest public betas you can switch the display from showing the timecode to showing the frame number. Is this what you are referring to?
