[SOLVED] HAP video aspect 1:1

Oleksandr Kovtun

Hi!

I'm currently working on a project with many high-res LED screens. I'm trying to re-encode all the videos into the HAP codec, but I'm facing a problem.

I usually use Shutter Encoder, but for some reason, it gives an error with 1:1 aspect video. Adobe ME converts such videos into HAP without any issues, but Isadora refuses to play them.

Has anyone faced this problem?

Thanks.

I've not run into that but if you need a quick and dirty solution, you can just render them out as 16x9 with black letterboxing on the left and right, then use a Chopper actor to cut off the letterboxing in Isadora.

Here's a file for that: using-the-chopper-actor-to-change-the-aspect-ratio-of-media-2024-06-20-3.2.6.izz

Thank you for the reply.

I've solved the problem by increasing the resolution a bit. The native was 1178x1178. When I resized it to 2000x2000 the problem went away.

But still strange ))

Shutter encoder uses FFMPEG under the hood - FFMPEG uses a slightly out of date implementation of HAP and requires resolutions in multiples of 4.

Source: https://github.com/FFmpeg/FFmp...

if (avctx->width % 4 || avctx->height % 4) {
        av_log(avctx, AV_LOG_ERROR, "Video size %dx%d is not multiple of 4.\n",
               avctx->width, avctx->height);
        return AVERROR_INVALIDDATA;
    }

The current version of HAP does not have that limitation (see odd dimension testing pack)

@fred, thank you.

Very useful information. I will keep it in mind for the future.
