Only problem would be adding having to add "-vb n" when things look bad. This would mostly hide the T2 from the user. Or, maybe have a GUI option to enable T2 acceleration and have it appended some additional T2 options to formats that are enabled for T2 acceleration and when T2 acceleration is enabled. So I can see this being included in cTiVo either via some more HB defaults (starts to get unwieldy I could imagine.) Something like 800-900kb gives a reasonably good picture. At this resolution the T2 encoders pick 256kb as the video bitrate. Some of the times I encode to 432p30 (i.e 768x432) for small devices. I don't if this is a HB bug or if the T2 encoders even have access to this. mpg TiVo file is always determined to be a 200kb source. The T2 encoders seem to read some tea leaves to determine the value the they will use. If your resulting file doesn't look so good: add an explicit -vb n to force a video bitrate. It seems safe to always include this if using the hardware encoders. I've only noticed this on 4K HEVC formats. It just does 2 one passes! So this saves half the encoding time. If the format uses the -2 or -two-pass: add -no-two-pass because the hardware doesn't support 2 pass. In "Video Options for Encoder" after the -Z"prefix": add -encoder vt_h264 or -encoder vt_h265 (this selects the hardware accelerated versions of h264 or h265, it also overrides anything selected in the JSON description.) The way I've been using the T2 is to modify the HB format to include the following: About the only thing that can be set that effects the encoding speed and/or quality is the video bit rate "-vb n" (where n is implicitly kb.) When one uses the hardware encoders in the T2 chips there are not many tuning options available. After reviewing my old notes and playing around a little with the latest HB 1.3.2 I have at the least some recommendations: I finally got around to looking at this again. I’ll be on vacation for 3 weeks, so no experiments from my end for a bit.

In general it seems like you need a higher bitrate using T2 hardware than software to get closer to similar quality.
Ctivo install files trial#
In general it’s very sparsely documented, and seems more trial and error with the VideoToolBox API. Found a few hints about knobs not available on FFmpeg that could help. My 2 x264 channels seem to be better when using FFmpeg, but I haven’t tried going down the route of selecting a different encoder by channel. FFmpeg glitches the audio and typically the audio sync multiple times per hour on my Cox channels. Waiting for Handbrake guys to pull support for T2 machines.

My plan is to just use T2 hardware for my typical 2-4 shows per night. CPU load for the hardware is low, maybe 20% or less, so a lot of time is left for software. Maybe on machines with more cores the software would close the gap. On my MacMini, the T2 hardware seems to be 3-4x faster than software. On T2 Mac’s, it seems like allow_sw defaults to on. Its a year old so might not mean anything anymore. Only other interesting thing I found was a way to resolve some ugly artifacts by increasing bufsize & maxrate to 9M. On another note, using no audio codec or just using “-acodec aac” gives QuickTime error -50 on playback.Įither adding "-ac 2" or "-ac 6” after "-acodec aac" seems to make it playable. Its much slower but will allow you to move forward. If you add “-allow_sw true” after the hevc_videotoolbox you can play around using the software only implementation. It appears that ffmpeg_edl_ac3.sh does some magic with the parameters that can’t seem to be corrected by putting the video options in a different field (or editing formats has some magic about using an old setting.) The "-vcodec hvec_videotoolbox -vtag hvc1” options have to come after the "-i ” otherwise you get a "Unknown decoder ‘hevc_videotoolbox’”. I think you might need some bash-foo on ffmpeg_edl_ac3.sh. I was already starting to play with ffmpeg directly on some TiVo downloads using some Googled tips.
