Re: How to change FPS with change of videolenght and audio pitch

avisynth, or maybe ffmpeg, wrapped in a short script is your best option.

Re: HandBrake taking 76 hours to encode REMUX to x265

I ended up having to take screenshots down to the second/frame and made comparisons that way. I don't have a proper set-up like what photographers have for side-by-side comparisons, so it was all done with my untrained eye. I zoomed the images just once, and moved really close up to the screen. Thi...

Re: HandBrake taking 76 hours to encode REMUX to x265

However, I'm slightly concerned that the file size produced is 4.8 GB from 19 GB. I mean, I'm happy it's much smaller, but I didn't expect it to shrink so much, so concerned about quality loss during the process. I use the default H.264 HQ 1080p30 preset. Audio is AC-3 5.1 passthrough. The video bi...

Re: Any Other Alternative to Handbrake ?

If you only need to change the container and not the streams (other than dropping some), HB is the wrong tool for you.

Use any muxer for that, like mp4box, subler, ffmpeg, etc. Much faster and no loss in quality.

It still depends on your source and settings. They may potentially all be used, or may have some relatively idle.

Re: HandBrake taking 76 hours to encode REMUX to x265

Don't bother with x265 for high quality HD encodes; x264 is way faster.

x265 shines at large frame sizes (4K+) or very low bitrates (low to medium quality); otherwise you don't get much for the speed hit.

HB isn't really the tool for HLS. ffmpeg can be scripted to do it pretty easily.

Re: 60fps H265 video stuttering on Roku Streaming Stick+

Figure out if it's a transfer problem or a decode problem.

Try lowering the bitrate peaks using vbv.

Try using the fastdecode preset.

The Production Proxy 1080p preset is intra-only. You can increase the resolution and save your own preset if you need higher resolution.

Re: Mad Men Season One Post-Processing - Is it Worth the CPU Cycles?

Absent an authoring error, which I don't think is the case here, the grain and/or softness is the intent of the creator. I'd drop the filtering, tune grain, and just eat the larger file size output to preserve what it's supposed to look like. OTOH if you want the grain gone, try hq3dn instead of nlm...

Re: Use Handbreak to copy DVD from specific time

HB's ability to start an encode at a specific time depends on HB's ability to get to that point in the video.

You'll need to use something intended for DVD ripping to get a clean copy, or a copy with the error portion removed.

Re: Best settings for compressing AVI files from 720x480 Camcorder

If you're going to edit later, keep the originals or make an editing-friendly (which will probably not be much smaller) encode with the Production presets. For lossless merging you can use ffmpeg or mkvmerge or probably one of the mp4 muxers for your platform. You can do this with the M2TS files or ...
