Detelecine / decomb issues

[edDV]

Ooh, I was able to get Handbrake to encode interlaced! On the Advanced tab add "tff" in the CLI options box at the bottom of the frame. It's case sensitive and you don't get any warning if the case is wrong. If there are options there already be sure to put a colon between the other options and tff. For example:

otheroptions=whatever:tff

So leave all the deinterlacing options off, add the tff flag, and encode. MediaInfo shows the scan type to be MBAFF and you can see the tff flag in the x264 command line options. Then hope your players play it properly.

Good news! Well done.

You rock! I've been fighting this issue with Batman The Animated Series! This solved the issue for me!

One question is how can I tell if my source is top or bottom field?

how can I tell if my source is top or bottom field?

In VirtualDub: open the file, add the bob double filter, step through the video frame by frame with the right arrow key. If you get two-steps-forward-one-step back motions you have the wrong order selected in the bob double filter.

In AviSynth you can use AssumeTFF().Bob(). Step the video frame by frame as with VirtualDub. If motions are ok your video is tff. Else bff. You can also use AssumeTFF().SeparateFields().

DVD is usually TFF. DV is BFF. Different capture devices will capture with different field orders. If you pick the wrong field order you will get very fast jerky motions on playback.

Thank you jagabo. A little over technical for me, but I'll do some more testing and learn

Wonderful post, and I've learned a lot.

Hey, jagabo, Sosigene, i admire your spirit of study.
