Problem editing a large file

Hi,

I recently upgraded my DVB-T capture software (Twinhan DTV 2.6x) and tonight I have created a very big file (4.7 GB) when recording a TV Show. Formerley, Twinhan software used to split recordings at around 3.5GB.

I very quicky realized I cannot edit such a big file : when I open it with VRD+ and also VRD 1.62 it take a very long time and only the first 10 seconds can be edited. The recording was almost 3 hours !

What can I do ?

Thanks !

MerleOne,

I routinely open, cut and trim files > 7GB with no problems what so ever.
Do as Anole suggests regarding your HDD. If your computer is under powered that may also be a major contributor to your problem as well.

Horsepower is important. If you don't have much CPU videoredo will bog down A LOT.

I have 37.9gb of gone with the wind (HD off TNT-HD) open right now, so it's not the software ... :)

Thanks.

Actually I was able to split the big file into 5x1GB chunks. The first 3 open fine within VRD. The last two have problems. I was however able to open the 4th one into VRD. After Quickfixing the file it is OK. The trouble is that the 5th chunk won't be opened : is there a way to have VRD quickfixed it without opening it first, for instance with a command file such as
"VideoRedo +Q <filename-in> <Filename-out>" ?

Does your software store files as transport streams?

If so, simply use hdtvtompeg2 to append all the parts into a single big file.

Assuming your video drive is NTFS, you don't have a 4gb barrier to worry about.

If the twinhan software can write to one contiguous file, that's the better way to go anyway, due to videoredo's linear nature : it edits one file at a time.

Actually TwinHan DTV output is "regular" MPEG2. VRDPlus finally accepted to load the initial big file and after a quickfix everything is OK.

Thanks all for your support.

That's the best way to go : just feed one big huge file into VRD.

Size pretty much doesn't matter - I have 5 hours of HDTV sized .ts loaded into it without problem ... almost 40gb worth!

Yes there is. You do not have to open a file first to QuickStream Fix it.

Start VideoReDo but do not open the file.

Click on the menu: Tools/QuickStream Fix
Click the "..." button to the right of the "Input Program Stream" box to select the file.

Using this method does not "load" it into VideoReDo and will QSF a file that would have trouble loading.
