mp4 file problems

Hello.

I recently changed the settings to make MP4 Files. It worked find on some 1/2 and 1 hour shows but when longer shows are converted and commercials removed, the mp4 files are smaller then they should be and I also end up with strange file names in the processed library. For example, Last nights Desperate Housewives program was 2 hours. I was expecting about an 1200 meg MP4 or thereabouts. I received a much smaller file but I get strange larger files in the processed library with names as sav4 and s9no with no extension but large enough to be the real video data. Im not sure what is going on. VRD handled the housewives file just fine when run manually but it was not recoded to mp4.

Any idea what to look for? I uninstalled VAP and reinstalled your latest version.

THanks!

Bill

What is your process flow? (QSF followed by AdScan? Autocut after adscan?)

What VRD profile are you using? Is it modified or original?

Please post the info on one of the problem input files (load file in VRD, hit Ctrl-L, put info in clipboard, and post here.)

The strange file names you are finding sound like temporary files that VRD creates when generating H.264 files, suggesting the process never finished.

When you say:
VRD handled the housewives file just fine when run manually but it was not recoded to mp4.
I'm not sure what you mean by "handled". Did you do "Save As" or "QSF" or what? Also, did you select a mp4 profile for the process? (If not that might explain why it was not encoded.)

In general VAP just sets up input and output file names and Output Profile, selects a VRD process (e.g., QSF or AdScan) and launches VRD. The Output Profiles names selected in VAP are obtained from VRD.

I have QSF, ADSCAN, Auto Cut after ad Scans and Delete Processed inputs checked.

For output profile, I selected H.264 (mp4) and .mp4 extension. I I didn't modify it, just used your default.

By the expression "Handled" I mean that videoredo alone will remove the commercials and make the MP4 file. Only when the VAP does it do I end up with segments... When I manually processed the file I just saved it, so now I'm trying it with "save as" to see what it does. I'll let you know if you think it's important.


Here is the info from VideoRedo.

Thanks for your help!!!!

When you say you end up with "segments", I'm not sure what you mean since you haven't used that term before. Is this just the various strange file names with no extensioins, or is it something else?

In your last post you said manually processing with VRD produced an MPEG4 file but this seems inconsistent with your prior statement:
VRD handled the housewives file just fine when run manually but it was not recoded to mp4.
Can you clarify that please?

I don't see any clues to problems in the input file info. Can you post the fragment of the VAP log file where it processes a "bad" file?

Also, what version of VRD are you running?

Is it correct that you experience the same problems with the latest VAP version as with the one you were previously running?

My only theory so far is that VRD is aborting the output process to the .mp4 file. This is consistent with a small (or no) .mp4 file and the file fragments ("segments" ?) you see.

To accurately mimic your VAP work flow manually in VRD, here is what you would need to do:
Load the input file and do a QSF using MPEG2-PS output profile, outputting to your VAP Temp(QSF) folder.
Load the .mpg file thus produced and run AdDetective and save with H.264 Output Profile to the VAP Output Folder.
