kmttg vs pytivo, mp4

It does take a while to convert to MPEG4 due to compression, but if you would be uploading back to the Tivo, then the time spent is worthless because it must transcode (download and convert) back to mpeg2.

 

I just made that setting to Auto, and testing on a video. The info says the size is 6GB when I know its much smaller than that.

 

Yes, its wrong size. The video file was an encode by KMTTG (PS3 encode profile) from the PS download (or DVD, I forget).

Update: the show now states size as 4.6GB after the transfer finished. Actual file size: MPEG2: 1.8GB, MPEG4: .9GB.

 

I think this is the encode file from KMTTG.

 

I am going to try to encode on another video (Using KMTTG, ffh264, med rate).

 

Update: The re-encoded video using h264/med rate, initial size was 6.4GB and after it finished, 2.3GB, on PyD off (apparently, I didn't hit save when I turned it to auto.)

Update2: The video size during transfer was 2.3GB and finished at .8GB. (on Auto.) Original MPG4 file at about 750MB, encoded from 1.8GB MPEG2 (h264/med rate.) The funny thing is the show transferred shows up as 2 shows. Delete 1 and it also deletes the other.

 

I haven't used pyTivo in a while.. Can you have it download files into "Directory A" then after transcoding is complete the finished file is put in "Directory B" which is being monitored, and uploaded back to the TiVo automatically?
If yes, maybe you could have an app like Tdarr (has scripts to use Handbrake or ffmpeg) handling conversions for you as it will scan "Directory A" and be configured to place finished files in "Directory B".

I've been using Tdarr to convert my entire library to h265

 

No, the transcoding is automatically done within the Tivo during the transfer, if its doing transcoding.

 

I'd say it worked and no transcoding on the final file. .84GB (TS uploads Auto) Vs. 4.6GB (TS uploads off)

 

Using KMTTG's encoding profile of 'ff_h264_Med_rate', I got about as much as 85% compression rate.

I tried it on some old black & white videos I still have, Adventures of Superman, the original size (after commercial cutted) was about 470mb, after encoded, about 350mb.
I then tried it with an episode of This Old house, 2.4GB, reduced to about 350mb.

 

Here is some MediaInfo on a video file before and after KMTTG encoding on ff_h264_Medrate profile.
