Question for VideoReDo users, have you ever seen this?

Hey all,

I'm using VideoReDo (VRD) TVSuite to cut commercials out of OTA recordings. In most cases, the recordings can be processed just fine with VRD, but once in a while I have a "glitched" recording. I am wondering if other VRD users have seen the same when editing their OTA recordings.

Whenever a glitched segment is encountered in the raw recording, VRD will report that some frame removal was done to maintain A/V sync. The VRD notification looks like this:



When the VRD output is reviewed, the glitched segment is pretty easy to spot. The glitches typically affect about 10 to 30 frames. Here are two screengrabs to illustrate:


SCREENGRAB 1 OF 2: A single frame just before glitch begins.



SCREENGRAB 2 OF 2: A frame within a 16-frame glitch.



Glitches like this occur infrequently, something like in the order of 1 recording in 10 exhibit the issue. I am wondering if other VRD users have ever seen this at all? If not, then maybe something is amiss in my home-built HTPC/DVR. Thanks in advance for any responses

Thanks. Would you kindly elaborate a little regarding the filter feature you wrote of? Thanks again

Looks like the glitched OTA recording phenomenon is a not uncommon one, though the cause of the issue seems to vary. None of my recordings, for instance, seem to have issues when the broadcast goes into/comes out of commercial segments. They seem to happen at random within the program itself, and they occur only once in a while, like only once in 10 hours of recordings.

I was wondering if I could mitigate the issue to the point of near elimination by doing anything differently on the HTPC/DVR, like maybe performing a weekly defragging on the HDDs where the recordings go.

Some have replied here that they have not seen any glitches in the final VRD output. My experience has been, however, that if VRD says that video and/or audio frames were removed to maintain A/V sync, then a glitch is present in the final VRD output. They may not be perceptible during playback, as they may affect less than 10 frames (i.e. "blink, and you'll miss it")... but if you are analyzing the output frame-by-frame, they can be spotted simply by noting - for film based programs - where the output exhibits a change in its 3:2 cadence (assuming the source is 24fps/24.976p filmed material that was telecined to 30fps/29.97i for television broadcast).

Thanks again to all who replied. This discussion has been very helpful, to me at least
