Settings for 1080i mpeg2 to 1080p mkv/mp4

I am messing around with the trial. I would like to know the best settings to convert recorded broadcast tv. Which is mpeg2 in a TS container, to h264 in an mkv (I would like to leave the AC3 audio alone)

I have always struggled to properly deinterlace 1080i material. Is there some settings somewhere that should work?

I attached a H264.MP4 Profile that I use for encoding MP4 video.
I has to zip it as the "upload" would not accept the extension on the Profile file.

I find that .mp4 type has some of the best support on other devices.
This profile encoding is SLOW. Change as needed.
The encode is set to 1.3Mbps Max 5Mbps. So a dvd level MPG file will be around 25-30% of original size.

Thanks I will check that out when I get home. So this profile will deal with interlaced material?
I guess a person would need multiple profiles? At least one for 1080i stuff and one for 720p stuff.

Do you have it set to keep 5.1 audio? I am hesitant to use mp4 because it also has to transcode the audio to AAC, I definitely don't want to downmix but if the 5.1 AAC sounds the same then no biggie.

I find AC3 to just "pass through" VRD in a MP4 file. Not sure on other audio types.
It is set to "deinterlace smart"

You can set up Profiles for each type of video you are working with.
Now the compression levels you want will have to be worked out.

For me a 5 Gig dvd MPG movie or a 30 Gig HD movie will all be taken down to 1.3Mbps.
That works for me but seems like most here prefer much higher bitrates.

Oh, if you make a change WHILE saving a file that change will be a "one off" for that save only.
To make a permanent Profile change you have to go to "Edit Output Profiles" and make the changes there.

Thanks, I didn't realize that AC3 could go into an MP4 container. I'll do some playing around next week. Right now I only have two samples to play with, my new tuner shows up Tuesday.

Yeah, the file types can be really fussy with the things they will keep or lose when a video is placed in them.

Some people want to get rid of a type of subtitle "teletype"?? and if you place the video in a certain container they will be gone.
Then the Audio types. What the containers will accept is a real mixed bag.

Now I could clean up my files (h264.mp4s) by having the video&subtitle files all in a single MKV file.
But somewhere here they mention that pulling a video file out of a MKV container will cause the loss of
some information (timing?).
The MKV container transfers some type of info from the video file into the MKV container so if you change the file type
of the video the info is gone with the container.
