i dont know crap about anything AV related because gently caress giving a poo poo about that, but when i play something on an imac running vlc through hdmi to a projector, the screen is often really dark its not dark when watching something off a dvd or bluray or whatever so what settings should i mess around with to make it less dark

does vlc still have a ui that looks like bad windows 95 software?

i made a screen recording for a class, captured it with a lossless codec. i then encoded it in h.246 dragging the quality slider all the way to "0 (high quality)", and the about two-and-a-half minute 720p video was barely over 2 megabytes and the image quality is prtty much flawless. (it was mostly a static image, but still) i guess what i'm trying to say is that my video codec was not a piece of poo poo.

Is it possible to force the encoder to only have 1 I frame?
|

Probablly not as hardware players need to have an i-frame every so often. also the standard says that a GOP can only be so long. i'm sure you could hack x264 to encode something like that but every scene change would look bad.

Weird anyway that's hosed up I mean it should just decode what is encoded Are there any apps/toys that can be used for messing around with the encoding? Like giving wrong I frames or other fuckery?

so i guess its scrub as but im using handbrake what cool advanced features can i use to make my encode cooler... i dont care about encoding time but i want cool small files or something i want to experiment but nothing makes any sense like a 7 year old playing doctor with the teenagers next door - i am willing but naive

also can we have a fight about constant quality vs 2 pass encoding

2 pass is alive

yes, it looked like the right-side picture, which is "pretty much flawless" lol if you think that a web video about clicking some buttons has to have 4:4:4 video

echinopsis posted:so i guess its scrub as but im using handbrake There is x264 placebo mode for all night encoding. If you were to pre-process the video and paletize it down (anime) you could get really small file sizes that way too. It's like how gif reduces colors. Dithering wouldn't help much but solid blocks of colors compress easier. Scrubbing the U and V channels of noise gets you a better picture with less bits. Some denoisers let you select individual channels in the components (not RGB since all h264 is YUV 4:x:x) You could probablly take the first pass of a completely different file that is the same length, and feed it in the second pass of the encode of a different file and watch the bitrate fluctuate in places it shouldn't crf is great when you're making a file for local playback to save space. 2-pass is good for fitting into a specific size, or staying your peak under a certain bitrate while maintining that specific file size. when they say "18 or lower is stupid don't go there" they are WRONG. Try feeding it a clean source you shot with a heavy film grain on top. 12 is probably visually lossless in that situation

what video player does this thread recommend for the Windows Operating System, since VLC is obviously not up to par

Media player classic home cinema. Built in decoders for stuff windows doesn't have (mpeg2) keyboard controls, hardware accelerated playback, minimal UI, color management if you profile your display. Also takes less than 3 seconds to open.

just download the matroska filter if you want to play pirated mkvs, or download media player classic-hc if you care about the thing looking right on your calibrated display.

Silver Alicorn posted:how do I calibrate my display You buy a hardware coloremeter that is appropriate for your display, attach it to the monitor, and run the software. You can get more complicated than that but being within ^E of 2% is good enough. Any more than that is really throwing money down the drain. Unfortunately software has to be "color managed" or else it displays the poo poo straight. This is okay if you have a display that is native sRGB, as everything assumes sRGB
