Privacy benefit of processing files client-side with no install
From 3 comments
Awesome work! The easy-of-use and privacy capabilities of this totally out-weight the somewhat slower performance. The safety one has with being able to do this in the browser,…
sktrdie on HNI tested with a 64MB, 124s long, 1152x720 .MOV video converted to .MP4 and here's what I saw: ``` modfy.video - 258 seconds native ffmpeg - 23 seconds ``` This was using a 2020…
whyleyc on HNNo need to manually install anything and sandboxing. Honestly if I had a suspicious video file I might prefer the browser option so that an ffmpeg exploit would not have access…

whyleyc on HNThis is a real cool tool and I would love to see more simple tools client-side only. However I have serious concerns about the performance. When developing a solver…
kevincox on HNI had a similar experience comparing DSP algorithms; native was faster across the board. It’s hard to get excited about WebASM if it’s slower.

No hardware acceleration and no threading or SIMD in this build
From 3 comments
It is definitely slower than using ffmpeg normally, but the idea is for more non technical users it adds convenience and they don't have to use a command line. Yeah this version…
cryogenicplanet on HNYes, SIMD as well, although they're not available on all browsers/devices.
markdog12 on HNCan you compare them when running native single threaded? WASM threading support isn't standard yet

Large files run out of memory because whole file is loaded into RAM
From 2 comments
I tried running something like this on my own, but I got OOM errors pretty quickly. 4 gigs isn't a lot when it comes to video processing. Hopefully wasm64 and WebGPU will make it…
hardwaregeek on HNI think this is as a result of the video have to be uploaded into RAM to be processed, this is definitely something I want to try to fix where I access the videos on the native…

Stream large files to disk instead of holding them in memory
From 2 comments
Is there a restriction on the size of the file or can it save the contents on the fly to disk like streamsaver?
ggonweb on HNGood job on your release, Curious, How is your version different from kagami or videoconverter versions, which were file conversions and they did not have streaming options, even…

Show the raw ffmpeg command line

I agree. It will keep getting better and I would much rather have these things available than not. It would be cool if the site provided the raw ffmpeg command line so that you…

Clearer file picker labels

Or change the text on the button. 'Add Files', 'Import Files', etc would be equally useful while not confusing.

Questions
How does performance compare to native ffmpeg
From 1 comment
How does the performance compare to running ffmpeg ad usual? I’m guessing that WASM means you don’t have access to things like hardware acceleration?

Does it work with CORS for transcoding YouTube videos
