Delogo and deinterlacing problem

[MokrySedeS]

Hello.

I have this 1080/50i H.264 HDTV capture and I'd like to encode it with x264, but I'm not sure how to handle it with avisynth.

About the "Delogo" part: I've heard about 2 ways - blur or "clean" removing if the logo is transparent.
I'm not sure if it is transparent enough, so here's a sample http://www.mediafire.com/?en0ay67bgu4tobr , please check it out and let me know which filter will be best for this and how to use it. (I'd like to get rid of that triangle too)

Regarding deinterlacing: I have no idea how to do it, I've only worked with progressive content so far, but I've heard that some filters are better than others. I want to achieve as good quality as possible, speed isn't much of a concern.

Your video is progressive and doesn't need deinterlacing. As for the logos, I don't believe either is translucent enough to be able to pull the video out from underneath them. There are a number of logo filters, for both VDub and for AviSynth. Here are some logo filters and guides to their use:

Your video is progressive and doesn't need deinterlacing.

That seems to be true, thanks. Weird that ffmpegsource and dgavcdec can't handle this properly. Also eac3to reported it as 50i. Is this normal?
Are there any alternatives except directshowsource?

After a second thought I think I'm going to leave the logo as it is if it can't be cleanly removed.

Like most PAL stuff, DVD and broadcast, it was encoded as interlaced even though the source is progressive. You have to examine the frames yourself and not rely on an outside app to tell you what you have.
