View Full Version : Removing the CC distortion line at the top of TTG exports?

I just got a new Tivo HD XL and have been playing around with Tivo To Go. I notice that all the export files I am getting out of TTG have that little 1-2 lines of distortion at the top of the screen, the thing that a little overscan would fix.

Is there any setting or adjustment I can make to get rid of those lines in the .tivo file export?

I am cleaning up the files using Video ReDo, and then turning the MPEGs into DIVX files. I have a little portable video server (basically a hard drive with Video Out) that I use to carry video files up to a rural vacation house with no other TV. I use DIVX because it makes most effective use of the limited space on the drive while still giving an adequate (not great) picture.

Alternatively, can anyone recommend a good, free program to crop the mpeg or finished DIVX file by a few lines without screwing up the resolution?

The TV at the vacation house is just a regular SD TV, so it may overscan enough to get rid of the issue on its own - but I would like to not get up there and find that line is visible on every show I copied to my little server.

Thanks for whatever help you can offer!

So, you can't crop and NOT change the resolution, but most programs don't care about the resolution, so you should be able to get away with cropping.

Alternatively, you can choose to crop and resize back to the original size, although that would smooth out the movie some.

If you use kmttg, it uses ffmpeg to re-encode the video, so you will need to add something like

-croptop 6

to the commandline. Kmttg can do all the work of fetching the show, cropping it, and re-encoding it to a divx.

Alternatively, you could use something like 'handbrake' in your last step and actively set your crop border before you start the re-encode.

I use TMPGENC for various things and it will do as you wish. It allows for a true Crop, or a Mask which leaves the resolution the same as the original but places pure black in the desired location. Both functions allow you to crop/mask any of the 4 edges by any number of pixels. You are viewing the video as you select these options so you can see what you are going to get.

If you Google it and specifically look for an older version (maybe < 2.5 before Pegasys took over) it used to be totoally free and fully fiunctional. In fact I don't know if the first few Pegasys versions even added any functionality, just put their name on it and started charging. Maybe they spiffed up the GUI?

Also BTW, this will be re-encoding so it is generally pretty slow. Certainly not fast.

Very helpful. I will play with both these suggestions. Appreciate it!
