Transcoding VideoReDo'd MPEGs with Dr DivX 1.05

[acanthis]

Slightly OT but has anyone else tried this yet? v1.05 is the latest version of Dr DivX - a program that, for me personally, has just never worked properly, but at least the last version was (sometimes) able to re-encode VideoReDo-edited MPEG2 files.

Doing some tests today I have found that the new version seems to get its initial analysis screwed up on the first edit point in the source file, then going on to assume that that position is the end of the file for encoding purposes. So, for example, the 1h40m file I wanted to test, which had had commercial breaks edited out of it, was identified by Dr DivX as only being 29 minutes long.

This isn't an issue for VideoReDo - every other program I have works with VideoReDo'd files just fine (Media Player, DVD Lab, Beyond TV, Hauppauge MVP, TMPEG DVD Author, VirtualDubMod etc) Just wondered if anyone else had tried and found same or different?

fyi I use DivX to archive the videos I've capped with my Hauppauge WinTV PVR USB2 (and subsequently edited with VRD) after they've been watched.

Quick Update. I've done some more tests. No doubt about it, Dr DivX 1.05 does not like VideoRedo'd MPEG files and has problems getting past an edit point - usually treating the file as if it were truncated at the first edit.

I am rather surprised, because that makes it the only program I've come across that complains! However, given my experiences of Dr DivX I know which program I'd blame for the problem, and its name doesn't begin with the letter V ;)

Email me at support@videoredo.com. I have something for you to try.

For anyone interested in this, see this topic: http://www.drdsystems.com/forum/phpBB2/viewtopic.php?t=201 for what looks like the solution; basically, disabling the option to create MovieFactory streams.

After doing this, Dr DivX quite happily parsed a 122 minute MPEG with five cuts. (As I write this, the transcoding process has just begun, so I can't definitely sign off until I've seen it produce a useable file - but it's looking good)

If you have other files that have been previously edited by VRD and want to convert to Divx, let me know. I'm thinking of adding an option that will fix all the temporal references that were changed by the "MF Compatability" checkbox.

My two hour test file transcoded fine, so it looks as though this one is now resolved.

The ability to fix files previously edited would be a very useful capability, but I do have other ways that I can get them converted to DivX (using VirtualDubMod, for example, which does read such files without complaint) but if you can easily add that function it would save a lot of time.

The next beta will have that capability using the QuickStream fix. Beta should be out sometime between today and Tuesday.

I'll keep an eye out. As I have a fair sized collection of stuff edited with MF streams, I shall be in a good position to test it.

Build 249 has just been uploaded to the beta forum. If you use the Tools>QuickStream fix it should insure that all temporal references start from 0.

Let me know if it works.

Just tested 249 on a 50 minute show with 4 commercial break edits that had been produced with MF streams. Processed the file fine (with Tools -> Quick Stream Fix) Dr DivX accepted it and transcoded it without difficulty.

Great work! ... And all that while the boys at DivX Networks are still sitting around with their fingers stuck up their collective asses thinking about whether to try and find the problem or to play another round of golf instead ;)

Thanks Dan. That's what I call service.
