I have some videos generated with Grok that when played back look like they're skipping, as if a few frames are just missing at that point. It's not that the audio cuts out or the video freezes completely — it's more like a sudden jump in the motion. It happens randomly, not always in the same spot, and the weird thing is it doesn't happen on every video I generate — some come out perfectly fine, others have these skips.

The videos are MP4, 416x752 (vertical format), 24fps. There are no duplicate or frozen frames — the motion just jumps from one point to another with no transition, as if those frames simply don't exist in the file.

I tried using RIFE in Hybrid to see if it could reconstruct the missing frames through interpolation, but I'm not sure if that's even the right approach for this kind of problem.

Has anyone dealt with something like this with AI-generated video? Is there a tool or workflow you'd recommend for detecting and reconstructing truly missing frames? Any help is appreciated, thanks!

I try this commandline to generate a "equivalent" mp4 at the same resolution

Code:

I'm wondering if there's a way to increase the encoding quality while maintaining the same or smaller file size, even at the cost of slower processing



and question n°2

this is my another source at 120fps

I need to generate an output at 25 or 50 fps "time corrected" as if it hadn't been shot at 120fps, is it possible?

x264 command:
Code:
ffmpeg -hwaccel auto -i "script.avs" -pix_fmt yuv420p -aspect 652:480 -vf setfield=bff -c:v libx264 -x264opts bff=1 -x264-params opencl=true -preset slow -crf 16 -c:a libfdk_aac -cutoff 18000 -vbr 5 "output.mkv"
i also tried to encode another avisynth script. the source is a 1080i mpeg2 file deinterlaced with qtgmc and upscaled to 4k for youtube. i'm not expecting realtime encoding with this of course, but in 2023 i could get about 2-4fps with hevc_nvenc. now it takes 20 minutes just for the encode to even start and i only get 0.05fps and maybe an slow increase to 1-3 overtime. same encoding settings and same script.

i'm trying to find some benchmarks of my cpu made when it came out (2017) and they aren't helpful. for x264 encoding benchmarks, a lot of them don't share the encoding preset or the resolution of the source, just framerates. so i can't tell if the speeds are accurate.

does anyone have any tips that could potentially help in slightly speeding things up? or are these speeds expected with my cpu? i could've swore it was faster a couple years ago.

hevc_nvenc command:
Code:
ffmpeg -hwaccel auto -i "script.avs" -pix_fmt yuv420p10le -c:v hevc_nvenc -rc vbr -cq 16 -qmin 16 -qmax 16 -b:v 0K -preset p7 -c:a copy "output.mkv"
maybe these have always been the speeds i got. i'm not sure. does anyone know what's up? ]]> Newbie / General discussions ENunn https://forum.videohelp.com/threads/420135-encoding-is-feeling-a-lot-slower-lately-am-i-going-crazy presentation of a website https://forum.videohelp.com/threads/420123-presentation-of-a-website?goto=newpost Thu, 26 Feb 2026 10:57:09 GMT hi guys, i launch a web site for a business and i need some help, i want to screen record the web site on iPhone and make a presentation video of it, o u have any idea of which type of app/site I can use ? ty hi guys, i launch a web site for a business and i need some help, i want to screen record the web site on iPhone and make a presentation video of it, o u have any idea of which type of app/site I can use ?

I'm new to the forum, had two strokes over five years ago, and considering I haven't been to to this in YEARS. It may forever until I understood glossary, but hopefully you'll help.

Years ago I was an editor on Sony TV used. Now, the only things I've touched are VLC media, https://www.videolan.org/vlc/index.html and--you may guess it--Microsoft's older "Movie Maker." (Are there any around?)

I have am Ultra Blu-ray Disc Player and Windows 11. Add to that, a bunch of little kids' video nearly 40 years old, and quite a few of child professional video tapes.

Can you refer me to software I can handle? Also, is there a way to do the captions. I appreciate it.

(And by the way, WHY is it that people invent brilliant things and no manual? If I get a new car, there's ALWAYS a manual. What's up with that?)

Hi, I am struggling to properly encode an mkv file to be made into a bluray .iso. What I have done so far:
1. Encode the file using handbrake. I have attached a screenshot of the settings I used.
2. Upload the file to tsmuxergui (which I had to build from source as the app was not working on my mac) to make the .iso
3. Test the .iso in Macgo bluray player (the only free one I could find). When I play the .iso, everything plays as long as I don't fast forward, then the video freezes and the audio continues to play. This also happens when I open the BDMV file in IINA.
4. I have also tried putting the mkv from handbrake into MKVToolNix then putting that mkv to tsmuxer but I have the same issue when playing the .iso

Any help regarding the proper bluray encoding settings, apps that will work on a mac, my process in general, etc. would greatly appreciated. I also have access to Leawo Bluray Creator but I am trying to avoid using it as I find that blurays created with it sometimes have quality issues.

it only leads to the print page option coming up (printer save as pdf)

and the entire discussion not even being shown. just the first page.

however, let's say i pick to save as text file.

the entire discussion get saved as a text file no problem.


is this just a problem on my end ? since the save to pdf is the default saving format.

so if this was happening to everyone if would have been fixed in a recent version.

anyway, using win 10 64 bit.

Hi, all. I dusted off my Sony HDR-CX360V camcorder, charged up the battery, shot some video. This unit uses memory card. Mine is a PNY 16 gb card.

Hi, all. I dusted off my Sony HDR-CX360V camcorder, charged up the battery, shot some video. This unit uses memory card. Mine is a PNY 16 gb card. I shot some video, played it back on the unit, and also played back some existing video that was on that card. All was good. I am an old koot, started shooting with a huge sony 8mm, then Hi-8, then my wife (bless her heart) surprised me with this unit. I used to shoot her public school music concerts (she taught in public school) using three recorders that I synced up using Vegas Video (hours of work, but I enjoyed it). Then we both retired, our children married, had children of their own, she and I both retired, and my digi-camcorder has been sitting unused ever since. Decided to dust it off, charged the battery, and shot some footage, downloaded Davinci Resolved, and resolved to re-kindle my aging interest. The battery for my CX350 charged right up, I reviewed some old existing footage residing on my memory card, all was good. I shot some footage, played it back on the cam, all good.

Then, I put the memory card into my USB card reader only to discover that my laptop running Windows 11, reported the card as empty. Obviously, that is not the case, since I can play footage (both new and old existing) via the camcorder. So, what might be causing the problem? I do a lot of digital still photography, and use this card reader all the time to transfer images from my DSLR to my laptop, so, I'm guessing the issue centers around some sort of incompatability between my laptop and either the card or the format of my camcorder footage. Windows explorer reports the card as empty, which it is not.

My camcorder has an HDMI port out, but I would have to find/purchase an HDMI-->USB to transfer the footage, and I'm guessing that would have to be done in real time after I locate/install some sort of capture utility for the PC. All my work was done in real time in the old days, but I have no clue if that option remains open to me now with the equipment I have (digital camcorder, Windows 11 PC).

I am stumped, but, fortunately, I'm not pressed for time . . . no "clients" waiting for their results, no family events screaming at me for video. Just an old guy (74 years young) looking to make things work in this new age.

Any suggestions would be appreciated.
