Question - Smart Rendering Analysis (Too Much Re-encoding) No.71153

I'm comparing TMPGEnc SR5 with VideoRedo. Specifically, if I import a .ts file (DVB-T2 Freeview HD UK programmes recorded via USB tuner), and then edit out the commercials and any unwanted parts, VideoRedo only re-encodes at the cut points (usually between 10-20 frames for each cut point), then saving the file is very quick. However, with TMPGEnc SR5, the smart render analysis highlights many other places that will be re-encoded, even though those parts have not been changed in any way. The amount of re-encoding undertaken by SR5 varies for each video file I have, but VideoRedo is consistent in that re-encoding is only performed at cut points. Sometimes, SR5 re-encodes up to 20% or more of the file, even though less than 1% of it has been edited.

I really like SR5 but the amount of re-encoding it does compared with VideoRedo is a deal breaker for me. I can't find a setting to alter the amount of re-encoding performed by SR5, but the smart encoding section does appear to be unreliable and inconsistent vs VideoRedo. Any ideas out there??

TIA

Do you have the latest version of TMSR5? They are version 5.0.18.24 as of this post.

Did you actually output with TMSR5 or just use the analyzer?

I have to concur with 'ukmark62'on his re-encoding observation. I too was very much surprised to see just how many frames were being re-encoded after a simple unfiltered cut; after all, in the advertising of TMPGEnc SR5, the implication is quite the opposite. In a recent edit of a 2 minute video, (where only 1 cut was being applied), I noticed that 300+ frames were due for re-encoding! The video is a 4K MP4 and runs at 25 fps; so what's that?.....12 seconds of re-encoding in a 2 minute vid...just say it need another cut and maybe another!
One work around I use is to do keyframe cuts only (which sort of defeats the apps purpose), another is to use 2 other freely available programs.
Another thing I've noticed is, if you fade the audio just at the video end - surprisingly, all the audio gets re-encoded.
Although it's not the one-stop quick-grab app I was hoping for; it still does a sturdy job of joining vids (Audio and Video are in synch every time!); it's never crashed and it's GUI is clear and intuitive. Ohh.....so close!
