... than take a look:

ffmpeg -i video.mp4 -ss 240 -filter_complex
"select='between(t,240,600)*not(mod(n,240))',subtitles=video.en.srt,scale=640:-1,tile=layout=2x2:padding=4"
-vframes 1 -q:v 2 test1.jpg




Most tools install FFMPEG (like Subtitle-Edit, etc.)

So this should work everywhere.

Params explained:

-ss 120 -to 1800 → limit the clip to 120–1800 seconds, but we only need "-ss" in this example

select='between(t,119.5,120.5)+...' → four exact time windows (with ±0.5s tolerance so FFmpeg actually finds a frame at those timestamps)

subtitles=... → render subtitles in sync with the original video timeline

scale=640:-1 → fix the width to 640 pixels, scale height proportionally

tile=2x2:padding=4 → build a collage of 4 images, arranged in a 2×2 grid, with 4-pixel spacing

-vframes 1 → output only a single image (the collage)

-q:v 2 → good JPEG quality


If you don't have FFMPEG:

ffmpeg is an incredible software. Some parts of it are still written in assembly to make it the most efficient.
I often use it, and I'm thinking about adding movie trailers here, like the ones I upload on YouTube:



About screenshots, if you use Linux (or if you have good development skills) you can see the software VongooB9 (a member here) has done:

I think this would boost this site a lot.

Youtube has the problem with modern scenes. Copyright and DMCA issues will be a problem. Especiallly for
- RKprime and
- Brazzers
scenes.

You should think about a size limit. Example: BangBros 4K-trailer have a size between 50MB and 200MB.

LQ trailers with 270p or 480p have a range from 0,5MB to 2MB.

Examples 320p (1,2MB):

Examples 720p (2,7MB):

August 1, 2023: Sneaky Threesome with Eden Ivy - Katy Rose, Eden Ivy, Yanick Shaft
Description: Eden Ivy has such a hot body that I can't stop staring at her. The way her ass curves, the way her tatoos look when she's showing off her tits, and don't even get me started on how beautiful she looks when she deep throats. Her and Katy Rose and a tag team when it comes to having sex and they definitely show it off here. They start talking about big dicks before they get horny and start going down on each other. What they don't know is that our boy Yanick is sneakily trying to get in to take a closer look. No one notices him jacking off outside so he makes his way in to hear these 2 gorgeous women moaning. He got too excited and jizzed all over which startled Eden. Both girls take him down before realizing his cock is bigger then their toys! With some quick thinking, both Eden and Katy were able to forget about the trespassing as long as they get to have some fun with a huge cock. Watch Eden's fat ass ride up and down a fat dick and don't forget about Katy's ass too! You're not going to want to miss this threesome.


Since I create a lot of trailers myself, I would love to create trailers for this site.

Yes, I almost lost my Youtube channel with a "full-clothed" scene... But youtube is still an important way to advertise about AVSubtitles I think.

You got it about the trailers: I struggle with the file size. I bought more storage for the site recently, but I could make it full very quickly if I store trailers :/
320p, x265, 300k bps (+ aac/64k audio) => I hardly go under 4MB for a one minute trailer.

This is a work in progress: https://www.avsubtitles.com/trailers.php

Ok, first of all default should be 270p (480x270). In ShotCut you can use 256k (average bitrate) or you test RF25 to RF32 with 48K AAC. Most (90% or more) of all
- BangBrosClips
- BangBus
- BangBros18
scenes are encoded with 48K AAC. It's enough for speach without sound.

Then we should get 1MB to 4MB with an 1-minute-trailer.

But yes, it might kill your dream of having all movie posters stored on your servers.

On the other hand, movie posters will be re-posted somewhere in the internert until the end of time. :-) ... I think.
