Selur's Little Message Board

Last 2 releases of Hybrid have same problem, when processing 1080i original camcorder video with QTGMC, a black bar will cover bottom of the video. But when using same clip repackaged in mkv, the problem goes away. Here are 2 samples of videos:

Taking the original camcorder extract (1440x1080@29.97fps, tff, PAR 4:3) applying QTGMC (with Bob), Hybrid uses:

and I see no black bars like you mentioned.

converting the content to 1:1 PAR and 1920x1080

I also see no black bars:

I also uploaded an encode of this to mediafire.
=> I can't reproduce your problem, but my guess is you messed up the settings somewhere. This does not look like a bug in Hybrid.

Ps.: loading the 'Repackaged to mkv without re-encoding.mkv', I basically get the same script (https://pastebin.com/179HcuKR) and outputs.

Ahh, it's the source filter. Using DGDecode seems to be the problem:

Depending on your setup enable either 'Use DGDecNV when available', 'Prefer BestSource' seems to help.

Cu Selur

Ps.: created a bug report in the dgmpegdec forum https://www.rationalqm.us/board/viewtopi...f=7&t=1444. => DG is on it.
There were some older versions of Hybrid that by default had 'Prefer BestSource' enabled. Also, since DGDecode doesn't support mkv, another source filter is used when the content is inside a mkv. Smile

I forgot to mention that I completely uninstalled & reinstalled using default settings. Thank you for finding the solution.

Uploaded a new dev version which comes with fixed version of DGDecode (thanks to DG) which helps with the sample on my system. Smile

Thank Cu Selur you for fixing the problem.
