I tried multiple times to upload a 1920x1080 video and export it as 1080 x 1920 for tik tok...but I couldn't do this, the last one was blocked at 75%, and it was an 30 seconds of 5 mb video..... I really need this website if everything works well!

Will take a look asap. Can you also try this maybe https://vidstudio.app/resize

Glad you're holding the "nothing leaves your machine" line. A lot of tools in adjacent categories added cloud sync early, the local audience didn't come back. If you can keep v1 and v2 fully client side you'll find the people who care. ffmpeg-on-wasm will hit a memory ceiling on longer videos, but most people opening a browser video editor are doing short clips anyway.

Thanks for encouragement. You are right ffmpeg-wasm doesn't really cut it for long videos but I have pivoted to web/audio codecs now, and there I can work based on streams at least for video. So once I harden the tools a bit more memory limits should be large enough to do some good editing.

The hvc1 and 10-bit failures a few comments up aren't a FFmpeg-wasm fallback thing, they're a WebCodecs browser-gap. Firefox's HEVC path is partial and 10-bit paths are worse. Chrome mostly works and Firefox fails on the exact files iPhones and modern Androids record by default. A "your browser can't decode this codec, try Chrome" nudge would probably spare people the bounce, especially on test imports from their pho…

Good idea. Once I am through the licensing ordeal I have a giant stack of errors to tackle which should increase usability.

Looks good. Good work on shipping! I love seeing video applications utilizing Web Assembly. However, it usually falls short in when it comes to longer video in the browser's sandboxed environment. How is the performance? Curious if you've tried using the FFmpeg libraries directly (libav), rather than compiling all of FFMpeg to WASM? I always end up using running FFmpeg directly since it's faster and more reliable, bu…

Yeah you are right about the wasm issues with video apps. The editor itself relies fully on web codecs and the rest of the tools are halfway migrated from ffmpeg wasm anyways. I did not look into any other alternatives for ffmpeg thinking that wasm will give me the next best thing to the cli tool and ofc since the browser is the main delivery mechanism the I was limited in my options. I have seen your project and it is really cool!

Congrats on shipping this! I went down the same path for videotobe.com, fully client-side with ffmpeg.wasm, and it fell over on longer videos. The memory ceiling and encode times pushed me to a cloud processing pipeline. You've managed to solve both, the WebCodecs plus Pixi plus ffmpeg.wasm split looks like the right decomposition in hindsight.I processed 3+ hrs of media using VidStudio and it held up. Nicely done!

Wow this is really cool thanks a lot for sharing I was a bit demotivated from all the errors I have on sentry ahahha. I did give ffmpeg wasm my best shot, even trying worker fs to deal with the memory problems but yeah a lot of effort for marginal gains imo. Video codecs are really impressive but they are raw in the sense that I underestimated how much ffmpeg carries by giving you a decode, transform encode pipeline.

I am really attracted to the idea of local running in-browser tools, since the website is then used only as a distribution medium which is super easy to use. And I really need such a tool, I was eager to test it. However on both my first and second try it failed. I tried to import a video clip recorded on a Pixel phone. In Firefox it failed with a following message: "Your browser does not support the codec "hvc1.2.4.…

Hey this is on my todo list and will make it a point to get back to you here once it is fixed. The main issue is that codec support is patchy most muxer software that I found has gaps in codec support and I had no clue but the codec names for audio and video seem to be named differently based on platform and browser even for some cases. Will be looking again at this topic asap and will get back to you here!

I love no accounts and no cloud a lot! Wondering if it support subtitle and transcript? It would be helpful for non-native speaker use case. Also, can you talk more about the use case difference between VidStudio vs. Finalcut/Imovie/Premiere? I am quite interested. Thanks

It is on my to do list to add automatic subtitles. The 3 editors you mentioned are backed by cloud juggernauts that either asked already or will ask for a perpetual licence to any content you process with them because they can and they also offer cloud options. I do have to say that they are probably more mature and feature rich than VidStudio at this point in time ahhaha

What is the performance difference between native FFmpeg and WebAssembly-translated FFmpeg running in a web browser?

Wasm ffmpeg is much slower for sure and multithreading for wasm ffmpeg is buggy you need to control threads per pipeline step to get it working.
